2. Related Art Statement

With the recent progress in information society, a variety of display devices are getting an increasing importance as one of machine interfaces. Of such displays, planar displays and particularly liquid crystal displays (LCD) have rapidly been distributed because of their small thickness, lightness in weight, low driving voltage, and small consumption of electric power.

Among the liquid crystal elements represented by liquid crystal display, the matrix type liquid crystal elements large in the amount of information are classified into active matrix type and simple matrix type from the viewpoint of method of driving.

In the active matrix type, thin-film transistors or diodes made of polysilicon, amorphous silicon or the like are set as non-linear elements by every image element. However, the active matrix type is complicated in the process of production and low in product yield, so that it is inferior from the viewpoint of enlargement of area, reduction of cost and enhancement of density. Thus, at the present time, the simple matrix type is advantageous over the active matrix type so far as price and productivity are taken into account.

As the liquid crystal element of simple matrix type which is in practical use currently, those using TN type and STN type liquid crystals are predominant. The optical response of these elements utilizes orientation of the average liquid crystal molecular axis in a particular direction in an electric field, which is based on the dielectric anisotropy of liquid crystal molecules. Accordingly, the limit of optical response speed of these elements is of milli-second order, which is insufficient in the light of the increasing amount of information of the current time. Although a variety of driving methods have so far been proposed with the aim of overcoming this difficulty, none of those proposals can give an essential solution to the problem, so that enlargement of capacity and enhancement of density are difficult to realize by those proposals. Further, these liquid crystals are so restricted in the angle of visual field and in the quality of display as to present another important difficulty.

In 1980, N. A. Clark and S. T. Lagerwall �Applied Phys. Lett., 36, 899 (1980)! proposed a liquid crystal element utilizing a bistable liquid crystal with the aim of solving the above-mentioned essential problem of liquid crystal element. As such bistable liquid crystal, ferroelectric liquid crystals exhibiting a chiral-smectic C phase are predominantly used.

The ferroelectric liquid crystal element is essentially characterized in that (1) it shows two optically stable states, and the optically stable states are maintained as they are even after removal of electric field (bistability) and (2) the optically stable states can be switched in micro-second order (high-speed response property). Further, the ferroelectric liquid crystal element is characterized also in that (3) the liquid crystal molecules respond in a plane parallel to substrate and the cell has a small thickness, so that the visual field angle-dependence of display is small (wide angle of visual field). Accordingly, the ferroelectric liquid crystal element requires no use of expensive non-linear element unlike active matrix type, and is expected as a high-quality large-sized display which can achieve a high display capacity and a high display quality by a simple matrix method.

Recently, M. F. Bone (U.S. Pat. No. 5,047,757; JP-A-3-20715) has reported an address method of matrix array type liquid crystal cell (inverse mode or .tau.-Vmin mode) using a liquid crystal material so controlled that response time of the liquid crystal takes a minimum value at a particular voltage. In such address method, a liquid crystal element is driven by using the positive gradient region of the voltage-dependence of response time, on the basis of the fact that response time of liquid crystal takes a minimum value at a particular voltage. The use of such a driving method expectedly gives a non-flickering good image.

A liquid crystal material which can be used in such inverse mode must have a negative dielectric anisotropy at least over the high frequency number range of 1-40 kHz, in addition to the characteristic properties conventionally required of ferroelectric liquid crystal materials, namely a phase series necessary for obtaining a good state of orientation or, in other words, a phase series changing, when slowly cooled, from isotropic phase via cholesteric phase and smectic A phase into chiral smectic C phase, and a low viscosity and a high-speed response property.

Although a number of liquid crystal materials have so far been reported either on paper or verbally, all these techniques have had some unsolved problem. One of the problems is to develop a liquid crystal material exhibiting chiral smectic C phase in a sufficiently wide temperature range and showing a minimum response time at a particular electric field.

Many properties are required of a ferroelectric liquid crystal material used in an actual ferroelectric liquid crystal element, whatever driving method is adopted. At the present stage, any single compound cannot fulfil all of such requirements, but a ferroelectric liquid crystal composition prepared by mixing together a plurality of liquid crystal compounds or non-liquid crystal compounds must be used. Up to today, however, there has been discovered no liquid crystal material simultaneously satisfying these practical requirements.

Although some aspects of the present invention may be involved in the conceptions of U.S. Pat. No. 4,834,904 (Japanese patent Kohyo 62-502620) and U.S. Pat. No. 5,209,866 (Japanese Patent Kohyo 2-503434) if the factors in the general formulas presented therein are favorably combined, the compounds of the present invention are by no means mentioned concretely in these prior patents.

When R.sup.1 and R.sup.2 are protecting groups of hydroxyl group, the above-mentioned groups exemplifying R.sup.1 and R.sup.2 can be used as the protecting groups. In addition, those groups which are conventionally used for protection of hydroxyl group are also usable for the purpose. As examples of such protecting group, the following can be referred to:

When the protecting group is R.sup.1 or R.sup.2, the de-protection can be effected in the following manner. The method of de-protection may be selected from a few ones depending on the kind of protecting group.

When R.sup.1 is an ester-forming group such as aliphatic acyl group or benzoyl group, the de-protection can be effected by hydrolyzing the ester linkage with an inorganic or organic acid such as hydrochloric acid, nitric acid, sulfuric acid or toluenesulfonic acid or with an alkali such as caustic soda or caustic potash. The amount of the acid or alkali is as follows. Thus, when an alkali is used, it is used in an amount not smaller than 1-10 moles, and when an acid is used, it is used in an amount of 0.01-30 moles, per mole of the ester. As the solvent, alcohols such as methanol, ethanol and propanol, and polar solvents such as tetrahydrofuran, dioxane, water and dimethyl sulfoxide are used.

When R.sup.1 O or R.sup.2 O forms an ether linkage, acids such as acetic acid, trifluoroacetic acid, trichloroacetic acid, hydroiodic acid, hydrobromic acid and boron trifluoride can be used in addition to the acids mentioned above, although bases such as lithium hydroxide and the like are also usable. When R.sup.1 and R.sup.2 are benzyl groups, the de-protection can be effected by a reductive treatment in the case of some compounds.

When the protecting group is a silyl group, the same acids as mentioned above can be used, in addition to which fluoride anion-containing de-silylating agents such as tetrabutylammonium fluoride, cesium fluoride, potassium fluoride and the like can be used for deprotecting the hydroxyl group.

In preparing a liquid crystal composition from a trans-olefin compound represented by the general formula (1), the compound to be mixed may be any of optically inactive compound and optically active compound. Either one of them or both of them may be mixed into the composition. Although the mixing ratio is not critical unless the liquid crystal phase is greatly deteriorated, a compound having no liquid crystal phase should preferably be mixed in an amount of 20% by mole or less, if such a compound is used.

Among the ingredients constituting the ferroelectric liquid crystal composition of the present invention, the optically inactive compounds to be mixed into the composition are, for example, as follows: ##STR14## wherein R.sup.c and R.sup.d represent alkyl, alkoxy or alkoxyalkyl group having 1-20 carbon atoms, and the compounds represented by the general formula (A) wherein f=0.

As the optically active compounds, the compounds represented by the general formula (A) wherein f=1 can be referred to, in addition to which the compounds represented by the following formula can also be used: ##STR15## wherein R.sup.e represents alkyl group having 1-20 carbon atoms or alkoxyalkyl group having 2-20 carbon atoms, R.sup.f represents a saturated or unsaturated alkyl group having 1-20 carbon atoms which may optionally be substituted by halogen atom, a saturated or unsaturated alkoxyalkyl group having 2-20 carbon atoms which may optionally be substituted by halogen atom or a hydrogen atom, and B.sup.1, B.sup.2 and B.sup.3 each represents the groups of the following formulas: ##STR16## wherein i' is an integer of 0-4; j' and k' are each an integer of 0-3; and p' and q' are 0 or 1, provided that, when B.sup.1 is a fused ring, p'+q'=0 or 1 and B.sup.2, B.sup.3 are single rings, and when B.sup.1 is a single ring, p'+q'=1 or 2, provided that when p'+q'=2, B.sup.2 and B.sup.3 are both single rings; Z' represents hydrogen atom or fluorine atom; n' is an integer of 0-10; and m', r', s' and t' each represents 0 or 1.

The liquid crystal element of the present invention can be utilized as various types of liquid crystal elements and display devices. Structure of the liquid crystal element of the invention is not particularly critical. FIG. 1 outlines one example of the ferroelectric liquid crystal element. In FIG. 1, 1 is polarizing plate, 2 is glass substrate, 3 is transparent electrode, 4 is electrically insulating, orientation-controlling film, 5 is ferroelectric liquid crystal, and 6 is spacer.

As an example of the liquid crystal element having a structure of FIG. 1, the surface-stabilization type ferroelectric liquid crystal displaying device can be referred to. This type of display is so constructed that two glass substrates 2 are placed in parallel with a very small gap to form a cell and a ferroelectric liquid crystal is filled into the gap so that the normal line of the smectic phase layer becomes parallel to the substrates.

Thickness of the ferroelectric liquid crystal layer 5 is dependent only on the gap between the two glass substrates 2 and the thicknesses of the transparent electrode 3 and insulating oriented film 4, both provided on the glass substrates in the direction of ferroelectric liquid crystal layer 5, and is usually in the range of from 0.5 to 20 .mu.m, and preferably from 1 to 5 .mu.m.

The transparent electrode 3 is placed so as to cover the glass substrate 2 of the liquid crystal layer side, and usually made of Indium-Tin Oxide, In.sub.2 O.sub.3, SnO.sub.2 or the like. On the liquid crystal layer side 5 of the transparent electrode 3, the insulating oriented film 4 is provided. Although the oriented film may be used in itself alone when the oriented film itself has a sufficient insulating property, an insulating film may be provided under the oriented films in order that both the films function as a whole as an insulating oriented film, if necessary.

As the oriented film, known film materials such as organic materials, inorganic materials, low molecular weight materials, high-polymeric materials and the like can be used. As the high-polymeric material, polyimide, polyamide, polyamide-imide, polyvinyl alcohol, polystyrene, polyester, polyester-imide, and a variety of photoresist materials may be used in accordance with need. When such a high-polymeric material is used as an oriented material, the orientation of liquid crystal molecules can additionally be promoted by a rubbing treatment, namely by rubbing the surface of the oriented film in one direction with cotton gauze, acetate-flocked cloth or the like, if desired.

As the insulating film, titanium oxide, aluminum oxide, zirconium oxide, silicon oxide, silicon nitride and the like can be used. The methods for forming these oriented film and insulating film may be selected in an optimum manner in accordance with the materials used.

For example, when a high-polymeric material is used, the polymeric material or a precursor thereof is dissolved in a solvent capable of dissolving these materials and then coated by the method of screen printing, spinner coating, dip coating, or the like. When an inorganic material is used, dipping method, vapor deposition method, slant vapor deposition method or the like may be adopted.

Although the thickness of said insulating oriented film is not particularly limited, it is usually in the range of 1 nm to 20000 nm, and preferably from 2 nm to 100 nm. The two glass substrates 3 carrying the insulating oriented film 4 and the transparent electrode 3 thereon are held at a prescribed distance through intermediation of spacer 6. As the spacer, a bead-form, fiber-form or film-form insulating material having a prescribed diameter or thickness and made of silica, alumina or a high-polymeric material can be used. After putting spacer 6 between two glass substrates 2 and sealing the circumference thereof with, for example, an epoxy type binder or the like, a ferroelectric liquid crystal can be sealed therein.

Outside the two glass substrates, one or two polarizing plates 1 are usually provided. FIG. 1 illustrates a case using two polarizing plates, in which the two polarizing plates are placed so that their polarization axes cross at a right angle, namely in the state of cross Nicol. The transparent electrode 3 is connected to the external driving circuit via an appropriate lead wire.

The compounds of the present invention represented by the general formula (1) have quite excellent properties as a liquid crystal material. Further, these compounds are useful as intermediate not only of liquid crystal materials but also of pesticides, medical drugs, etc. According to the process of the present invention, the objective trans-olefin compounds can be obtained in a high selectivity. The liquid crystal composition of the present invention are quite excellent in properties, for example in that they have a broad liquid crystal temperature range, and a liquid crystal element using said liquid crystal composition is successfully usable as a display element, optical shutter, and the like.

Example 168

Liquid crystal parent composition (1-a) was prepared by mixing together the following compounds at the compounding ratio mentioned below.

TABLE 5______________________________________Constituents and compounding ratio of parent composition (1-a) RatioCompound used (mol %)______________________________________ ##STR723## 25 ##STR724## 25 ##STR725## 50______________________________________ (All the double bonds are transform.)

The composition was put between two glass substrates carrying their respective transparent electrodes and oriented polyimide films. The gap between the two glass substrates was adjusted to 2 .mu.m with a spacer. Two polarizing plates having 90.degree.-rotated planes of polarization were provided outside the two glass substrates to prepare a liquid crystal element. The axis of polarization in the incident side was made to coincide with the direction of rubbing of the oriented polyimide film.

Comparative Example 1

Liquid crystal composition (1-b) was prepared by the use of phenylpyrimidine compounds represented by the following general formula: ##STR726## wherein R and R'0 each represents an alkyl group, which are generally used as ingredient of parent composition.

Next, phase series of these liquid crystal elements were measured.

Phase series were determined by heating a liquid crystal element to a liquid state, thereafter cooling the liquid crystal element at a rate of 2.5.degree. C. per minute, and observing the texture by means of polarizing microscope. Table 7 lists the results obtained in Example 168 and Comparative Example 1, wherein the unit is .degree.C.

It is apparent from Table 7 that a parent composition constituted from a trans-olefin compound has a phase series necessary for acquiring a good orientation, namely liquid phase.fwdarw.nematic phase.fwdarw.smectic A phase.fwdarw.smectic C phase, and the temperature range of smectic C phase is broader than that of composition (1-b) constituted from a compound having no trans bond and the upper limit of the temperature range is higher than that of composition (1-b). Accordingly, parent compositions constituted of trans-olefin compounds are superior to those constituted of compounds having no trans bond.

Example 169

Next, a ferroelectric liquid crystal composition (2-a) was prepared by mixing the parent composition (1-a) of Example 168 with the following optically active compound at the compounding ratio mentioned below.

Comparative Example 2

Ferroelectric liquid crystal composition (2-b) was prepared by mixing the same optically active compound as used in the preparation of (2-a) into the parent composition (1-b) of Comparative Example 1.

Next, phase series, spontaneous polarizations, tilt angles and response times of these liquid crystal elements were measured.

Spontaneous polarization was calculated according to the triangular wave method mentioned in Japanese Journal of Applied Physics, Vol. 22, Part 2, Pages L661-663 (1993).

Tilt angle was determined by placing a liquid crystal element on a sample table, applying a rectangular wave voltage of 10 V/.mu.m thereto, measuring the angles .theta.1 and .theta.2 of the extinction positions with regard to electric field and polarization while rotating the sample table, and taking one halves of the angles as tilt angles.

Response time was determined by projecting light to a liquid crystal element, inputting a rectangular wave of .+-.10 V/.mu.m, and measuring the period of time required for changing the light transmittance of liquid crystal element from 10% to 90% at the time of inversion of polarity.

Results of Examples 169 and Comparative Example 2 are summarized in the following table, wherein the unit is .degree.C.

It is apparent from Table 10 that the composition (2-a) containing a trans-olefin compound has a phase series necessary for acquiring a good orientation, namely liquid phase.fwdarw.cholesteric phase.fwdarw.smectic A phase .fwdarw.chiral smectic C phase, and upper limit temperature of the chiral smectic C phase was higher than that of the composition (2-b) containing a compound having no trans bond. Further, liquid crystal composition (2-a) was greater than composition (2-b) in induced spontaneous polarization and tilt angle. Accordingly, the amount of optically active compound could be made smaller in the case of trans-olefin compound than in the case of a compound having no trans bond.

Table 10 also demonstrates that composition (2-a) is smaller than composition (2-b) in response time at 20.degree. C. That is, a composition using trans-olefin compound is superior to a composition using a compound having no trans bond in high-speed response property.

It can be concluded from the above that a composition using a trans-olefin compound is superior to a composition using a compound having no trans bond.

Comparative Example 3

For comparison with Example 170, liquid crystal composition (3-b) was prepared from a bicyclic phenylpyrimidine compound having no trans-olefin structure on its side chain, from which a liquid crystal element was prepared in the same manner as in Example 170.

Next, phase series of these liquid crystal elements were measured. Phase series was determined by heating a liquid crystal element to a liquid state, cooling the liquid crystal element at a rate of 2.5.degree. C. per minute, and identifying the phase series while observing the texture by means of polarizing microscope. Table 13 summarizes the results of Example 170 and Comparative Example 3. The data shown in Table 13 are those obtained by cooling the sample from liquid state until crystallization and thereafter elevating the temperature at the same rate. The unit is .degree.C.

It is apparent from Table 13 that a liquid crystal parent composition constituted of a trans-olefin compound has a phase series necessary for acquiring a good orientation, namely a phase series of changing from isotropic phase, passing nematic phase and smectic A phase and reaching smectic C phase when cooled slowly, while composition (3-b) constituted of a compound having no trans-olefin structure exhibits only smectic C phase as a liquid crystal phase.

Further, as to the temperature range of smectic C phase, liquid crystal parent composition (3-a) is broader than liquid crystal parent composition (3-b) in both upper and lower limits. Accordingly, a liquid crystal parent composition constituted of a trans-olefin compound is superior to that constituted of a compound having no trans-olefin structure.

Example 171

Next, ferroelectric liquid crystal composition (4-a) was prepared by mixing the liquid crystal parent composition (3-a) with the following optically active composition at the following compounding ratio.

Next, liquid crystal elements similar to that of Example 168 were prepared from these ferroelectric liquid crystal compositions, and phase series were evaluated. The data shown in Table 16 are those obtained at the time of cooling the samples from liquid state at a rate of 2.5.degree. C. per minute.

It is apparent from Table 16 that the ferroelectric liquid crystal composition (4-a) constituted of a trans-olefin compound has a phase series necessary for acquiring a good orientation, namely a phase series which, at the time of slow cooling from isotropic phase, changing via cholesteric phase and smectic A phase to chiral smectic C phase, while the composition (4-b) constituted of a compound having no trans-olefin structure changed directly to chiral smectic C phase simultaneously with slow cooling from isotropic phase, without exhibiting neither cholesteric phase nor smectic A phase.

Further, the ferroelectric liquid crystal composition (4-a) was higher than (4-b) in the upper limit of the temperature range of chiral smectic C phase.

The ferroelectric liquid crystal composition (4-a) constituted of a trans-olefin compound had a phase series necessary for acquiring a good orientation. Thus, the electric field dependence of response time (.tau.-V character-istic) was measured to evaluate the performance as inverse mode type liquid crystal material. The "response time" herein referred to means a minimum pulse width giving a good switching state at the time of inputting monopolar pulse.

.tau.-V characteristics were evaluated in the following manner. A monopolar pulse having a duty ratio of 1:400, as shown in FIG. 2, was input to cause switching, and the change in the quantity of transmitting light was detected by means of photomultiplier. After current-voltage conversion, the change was input into oscilloscope and visually examined.

The minimum pulse width giving a good switching state, namely the minimum pulse width retaining a memorial property, at an electric field was taken as the minimum pulse width at that electric field. As used herein, the term "not retaining memorial property" means that the contrast ratio between two stable states decreases. By plotting the minimum value of pulse width, a .tau.-V characteristic curve was obtained. Minimum value of input electric field in the .tau.-V curve was expressed by Emin, and the pulse width at this point was expressed by .tau.min

FIG. 3 illustrates the .tau.-V characteristic curve of Example 171 at 25.degree. C. The ferroelectric liquid crystal composition (4-a) had Emin value of 14 V/.mu.m and .tau.min value of 148 .mu.s, demonstrating its excellence as a liquid crystal material for inverse mode.

Example 172

Ferroelectric liquid crystal composition 5 was prepared by mixing a compound represented by general formula (1) and other compounds at a compounding ratio shown in Table 17 (% by mol, hereinafter the same).

Using this liquid crystal composition, a liquid crystal element was prepared in the same manner as in Example 168.

Next, electric field dependence (.tau.-V characteristic curve) of the minimum pulse width of this liquid crystal composition was measured in the following manner. Thus, a monopolar pulse having a duty ratio of 1:400 was input to the liquid crystal element, and the change in the quantity of transmitting light was detected by means of photomultiplier. After current-voltage conversion, the change was input into oscilloscope and visually examined. The minimum pulse width retaining a memorial property at a voltage was taken as the minimum pulse width at that voltage. As used herein, the term "not retaining memorial property" means that the contrast ratio between two stable states decreases. FIG. 4 illustrates the .tau.-V characteristic at 25.degree. C. In FIG. 4, the minimum pulse width capable of retaining memorial property is defined as .tau.min, and the electric field at that time is defined as Emin. The composition of this example had .tau.min value of 94 .mu.s and Emin value of 20 V/.mu.m. The .tau.-V characteristic curve of FIG. 4 demonstrates that this liquid crystal composition 5 can be used as a composition for .tau.-Vmin mode.

Example 173

Ferroelectric liquid crystal composition 6 was prepared by mixing a compound represented by the general formula (1) and other compounds at the compounding ratio shown in Table 18.

FIG. 5 illustrates the .tau.-V characteristics measured in the same manner as in Example 172. In this liquid crystal composition 6, .tau.min was 167 .mu.s and Emin was 18 V/.mu.m. It is apparent from FIG. 5 that this liquid crystal composition 6 can be used as a composition for .tau.V-min mode.
