Description

TECHNICAL FIELD

The present disclosure relates to an optical film and an optically anisotropic body which have excellent in-plane thickness uniformity and improved in-plane uniformity in optical properties, and to a polarizing plate, a display device and an antireflection film in which the optically anisotropic body is used.

The present disclosure also relates to a polymerizable compound, a polymerizable composition and a polymer, which may be used in the preparation of the aforementioned optical film and the optically anisotropic body, and to a compound which may be used in the preparation of the polymerizable compound.

The present disclosure also relates to a method for producing the aforementioned polymerizable compound, and, a method for using the aforementioned compound.

BACKGROUND

Examples of retardation plates used in various devices such as flat panel displays include quarter-wave plates that convert linearly polarized light to circularly polarized light and half-wave plates that perform 90° conversion of the plane of vibration of linearly polarized light. These retardation plates can accurately impart a retardation of ¼λ, or ½λ of the wavelength of light with respect to specific monochromatic light.

However, conventional retardation plates have a problem that polarized light that passes therethrough and is output therefrom is converted to colored polarized light. Since a constituent material of the retardation plate has a property of wavelength dispersion with respect to retardation, and a distribution arises in the polarization state of each wavelength for white light, which is a composite wave in which light in the visible region is mixed, it is impossible to achieve accurate adjustment to polarized light with a retardation of ¼λ, or ½λ, over the entire wavelength region of input light.

In order to solve this problem, various retardation plates which are wideband retardation plates that can achieve uniform retardation with respect to light over a wide wavelength region having so-called reverse wavelength dispersion have been considered.

On the one hand, it has been desired to reduce the thickness of the flat panel display device as much as possible along with an improvement in functionality and widespread use of information terminals such as mobile personal computers and mobile phones. Therefore, a reduction in the thickness of the retardation plates which are components has also been desired.

In terms of methods for achieving thickness-reduction, a method in which a retardation plate is produced by applying a polymerizable composition comprising a low-molecular weight polymerizable compound onto a film substrate to form an optical film has been regarded as the most effective method in recent years. For this reason, polymerizable compounds capable of forming optical films having excellent reverse wavelength dispersion or polymerizable compositions containing such compounds have been widely developed.

Specifically, polymerizable compounds have been provided for use in the production of an optical film such as a polarizing plate or a retardation plate capable of uniform conversion of polarized light over a wide wavelength band (for example, refer to PTL 1).

SUMMARY

Technical Problem

Here, in order to exert an excellent reverse wavelength dispersion over a wide wavelength band, optical films and the like are required to exhibit ideal retardation characteristics such that the retardation value increases in proportion to the wavelength on both the longer wavelength side and the short wavelength side. Further, accompanying the large area of a liquid crystal display (LCD) and an organic EL display (OLED), the demand for in-plane uniformity of an optical film or the like has been growing. However, as described in PTL 1, the conventional polymerizable compounds have room for improvement of the application properties, and improvement in the in-plane uniformity of the film thickness for the optical film to be obtained, and consequently, the in-plane uniformity in the optical properties such as the retardation.

The present disclosure was conceived in view of the above-described circumstances, and an object of the present disclosure is to provide a polymerizable compound, a polymerizable composition and a polymer, which are able to form an optical film and an optically anisotropic body which have excellent in-plane thickness uniformity and improved in-plane uniformity in optical properties.

Another object of the present disclosure is to provide a compound which can be used in the preparation of the aforementioned polymerizable compound.

Still another object of the present disclosure is to provide a method for producing the aforementioned polymerizable compound, and, a method for using the aforementioned compound.

Yet another object of the present disclosure is to provide an optical film and an optically anisotropic body which have excellent in-plane thickness uniformity and improved in-plane uniformity in optical properties, and a polarizing plate, a display device and an antireflection film in which the optically anisotropic body is used.

Here, the film thickness of the optically anisotropic body (liquid crystal polymer film) was measured by scratching the optically anisotropic body of the optically anisotropic body with a transparent glass substrate with a needle, and the step height was measured by DEKTAK 150 surface profilometer (manufactured by ULVAC, Inc). The results are shown in Table 2-1, Table 2-2, Table 2-3 and Table 2-4.

α is smaller than 1, and β is larger than 1 when an ideal wideband wavelength dispersion i.e., a reverse wavelength dispersion is achieved. It is understood from Table 2-1, Table 2-2, Table 2-3 and Table 2-4 that the optically anisotropic bodies produced from the polymerizable compounds of Examples 1 to 8, Examples 17 to 20 and Examples 25 to 33-2 have an ideal wideband wavelength dispersion i.e., a reverse wavelength dispersion.

Further, the polymerizable compounds of Examples 1 to 8, Examples 17 to 20 and Examples 25 to 33-2 have a smaller Δn, and in order to obtain the same retardation, it is necessary to make the application of the polymerizable compound of Comparative Example 1 thicker, and as a result, it is anticipated that control of retardation and uniformity of film thickness can be more easily performed.

The results are shown in Table 3-1, Table 3-2, Table 3-3 and Table 3-4.
