BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display panel, and more particularly to a liquid crystal display (LCD) panel.

2. Description of Related Art

Display viewing angles of LCDs are required to be increasing largely in the market. Currently, the common wide viewing angle technology is multi-domain vertical alignment LCD panel, which adopts an alignment structure to make liquid crystal molecules in different regions to tilt along different directions, thereby achieving the effect of wide viewing angle. However, the disclination of liquid crystal molecules on the periphery of the alignment structure often occurs, resulting in the light leakage. Therefore, an alignment manner of polymer-stabilized alignment (PSA) together with a pixel electrode having a plurality of micro slits to form multi-domain alignment is proposed to solve the problem of the poor display effect of the multi-domain vertical alignment LCD panel.

FIG. 1 shows a pixel structure of the polymer-stabilized alignment LCD panel (PSA-LCD) in the prior art. Referring to FIG. 1, a pixel structure 100 is electrically connected with the scan lines 102 and data lines 104, and the pixel structure 100 includes a first active device 106, a second active device 108, a first pixel electrode 110, and a second pixel electrode 120. The first active device 106 and the second active device 108 are electrically connected to the first pixel electrode 110 and the second pixel electrode 120 respectively. The first pixel electrode 110 and the second pixel electrode 120 are spaced by a main slit 130, such that the first pixel electrode 110 and the second pixel electrode 120 may have different display voltages. Furthermore, the first pixel electrode 110 has a plurality of fine slits 112, and the second pixel electrode 120 has a plurality of fine slits 122.

The disposition of fine slits 112 and 122 makes the liquid crystal molecules tilt along different directions, so as to exhibit a display effect of wide viewing angle. In the orientation of reference coordinate C, the pixel structures 100 is preferably designed to make the liquid crystal molecules located above the first pixel electrode 110 and the second pixel electrode 120 tilt along the directions of 45°, 135°, 225°, and 315°, so as to achieve an optimal display effect. However, the liquid crystal molecules located above the main slit 130 tilt along the directions of 90° and 270°, thus adversely affecting the display effect of the pixel structures 100. The simulation results show that when viewing at a large viewing angle in the horizontal direction, the tilting of liquid crystal molecules along the directions of 90° and 270° may improve the medium and low gray-scale display brightness and decrease the high gray-scale display brightness. Therefore, the tilting of the liquid crystal molecules along the directions of 90° and 270° may aggravate the color washout and the color shift of display images.

Based on the above, the pixel structures 100 may further include a shading layer (not shown) located above the main slit 130, so as to eliminate the color washout and the color shift of display images. However, the design of shading layer limits the display aperture ratio of the pixel structures 100. Therefore, the above problems needs to be overcome while maintaining the display aperture ratio and the wide viewing angle display effect in the wide viewing angle LCD panel.

DESCRIPTION OF EMBODIMENTS

FIG. 2A is a schematic top view of a polymer-stabilized alignment liquid crystal display panel (PSA-LCD) according to a first embodiment of the present invention, and FIG. 2B shows a pixel structure of the LCD panel in FIG. 2A. Referring to FIG. 2A, an LCD panel 200 includes a first substrate 210, a plurality of scan lines 212, a plurality of data lines 214, a plurality of pixel structures 216, a second substrate 220, and a liquid crystal layer 230. The scan lines 212, the data lines 214, and the pixel structures 216 are disposed on the first substrate 210. The pixel structures 216 are electrically connected to the corresponding scan lines 212 and data lines 214. The liquid crystal layer 230 is disposed between the first substrate 210 and the second substrate 220.

Each of the pixel structures 216 includes a first active device 218a, a first pixel electrode 240, and a second pixel electrode 260. The first pixel electrode 240 is electrically connected to the first active device 218a. A V-shaped main slit 250 is formed between the first pixel electrode 240 and the second pixel electrode 260 and has a tip 252 and two branches 254 connected to the tip 252. The tip 252 directs towards the second pixel electrode 260. The edges of the first pixel electrode 240 and the second pixel electrode 260 adjoining each branch 254 are substantially parallel. Furthermore, the second substrate 220 has an opposite electrode 222.

In detail, referring to FIG. 2B, in order to improve the quality of the display image, the second pixel electrode 260 may be electrically connected to a second active device 218b disposed on the first substrate 210, such that the first pixel electrode 240 and the second pixel electrode 260 has different display voltages. When the LCD panel 200 is displaying, the potential difference between the first pixel electrode 240 and the opposite electrode 222 is, for example, greater than or equal to the potential difference between the second pixel electrode 260 and the opposite electrode 222, thus exhibiting different display brightness. In practice, in the LCD panel 200, the first substrate 210 may further have a plurality of first capacitor electrodes 272 and a plurality of second capacitor electrodes 274 (only one is shown as an example herein). The first capacitor electrodes 272 and the second capacitor electrodes 274 are respectively located below the first pixel electrode 240 and the second pixel electrode 260, such that the display voltages of the first pixel electrode 240 and the second pixel electrode 260 are different.

As the display voltages of the first pixel electrode 240 and the second pixel electrode 260 are different, the tilting directions of the liquid crystal molecules locating between the first pixel electrode 240 and the second pixel electrode 260 may influence the display quality of the LCD panel 200. Accordingly, the present invention propose a V-shaped main slit 250 formed between the first pixel electrode 240 and the second pixel electrode 260 to eliminate the situation that the display quality is degraded caused by the undesired tilt directions of the liquid crystal molecules. The first pixel electrode 240 and the second pixel electrode 260 are described in more detail hereinafter to illustrate the present invention.

Each of the first pixel electrodes 240 includes a first interlacing pattern 242, a plurality of first strip patterns 244, and a V-shaped connection pattern 246. The first interlacing pattern 242 has, for example, a first central portion 242a and defines at least four regions I, II, III and IV. The first strip patterns 244 are substantially located in regions I, II, III and IV. The first strip patterns 244 in each of the regions I, II, III or IV are substantially parallel. One end of each of the first strip pattern 244 is connected to the first interlacing pattern 242, and the other end is far away from the first interlacing pattern 242. The V-shaped connection pattern 246 connects a part of the first strip patterns 244 and the first interlacing pattern 242. The V-shaped main slit 250 is located between the V-shaped connection pattern 246 and the second pixel electrode 260. Furthermore, a plurality of first fine slits 248 is formed between the first interlacing pattern 242 and the first strip patterns 244 of each of the first pixel electrode 240.

Each of the second pixel electrodes 260 includes a second interlacing pattern 262 and a plurality of second strip patterns 264. The second interlacing pattern 262 has a second central portion 262a and defines at least four regions I, II, III and IV. Two neighboring regions I and II are adjoining to the V-shaped main slit 250. The second strip patterns 264 are located in regions I, II, III and IV, and the second strip patterns 264 in each of the regions I, II, III or IV are substantially parallel. One end of each of the second strip patterns 264 is connected to the second interlacing pattern 262, and the other end is far away from the second interlacing pattern 262. For example, a plurality of second fine slits 266 are formed between the second interlacing pattern 262 and the second strip patterns 264 of each of the second pixel electrodes 260.

In practice, in the pixel structures 216, one side of the first pixel electrode 240 adjacent to the second pixel electrode 260 is connected by a V-shaped connection pattern 246. Therefore, the edge of the first pixel electrode 240 adjacent to the second pixel electrode 260 is closed and defines one edge of the V-shaped main slit 250. Meanwhile, in the second pixel electrode 260, the second strip patterns 264 located in regions I and II respectively just have the same extension direction as the V-shaped connection pattern 246 of the first pixel electrode 240, so as to define the other edge of the V-shaped main slit 250. Furthermore, the width of each branch 254 in the V-shaped main slit 250 is about 1 μm to 12 μm.

When the LCD panel 200 is displaying, the liquid crystal molecules located in regions I, II, III and IV respectively tilt along the extension direction of the first fine slits 248 and the second fine slits 266, for example, in the directions of 45°, 135°, 225°, and 315°, thereby achieving wide viewing angle display effect. Moreover, the liquid crystal molecules located at the junction of the first pixel electrode 240 and the second pixel electrode 260 will not tilt along the direction of 90° or 270° due to the disposition of the V-shaped main slit 250 and will not cause influence on the display effect of the LCD panel 200.

In detail, FIG. 2C is a simulation diagram of tilt directions of the liquid crystal molecules above the V-shaped main slit. Referring to FIGS. 2B and 2C, the liquid crystal molecules 232a on the edge of the first pixel electrode 240 adjacent to the V-shaped main slit 250 may be influenced by the V-shaped connection pattern 246 to tilt towards the interior of the first pixel electrode 240, i.e., the liquid crystal molecules 232a substantially tilt along the extension direction of the first fine slits 248. Meanwhile, the potential difference between the first pixel electrode 240 and the opposite electrode 222 is, for example, greater than the potential difference between the second pixel electrode 260 and the opposite electrode 222. Therefore, the liquid crystal molecules 232b on the edge of the second pixel electrode 260 adjacent to the V-shaped main slit 250 may be influenced by the direction of the electric field between the second pixel electrode 260 and the first pixel electrode 240 to substantially tilt along the direction of the second strip patterns 264. In other words, the tilt direction of the liquid crystal molecules 232b substantially coincides with the extension direction of the second fine slits 266.

If the extension direction of the first fine slits 248 and the second fine slits 266 is, for example, 45°, 135°, 225°, and 315°, the tilt direction of the liquid crystal molecules 232 in each branch 254 of the V-shaped main slit 250 varies, for example, from 315° to 45° or from 225° to 135°. In this manner, the liquid crystal molecules 232 in the V-shaped main slit 250 is not liable to tilt along the direction of 90° or 270°. Therefore, when viewing the images displayed by the LCD panel 200 in the horizontal direction, the color washout and the color shift from different viewing angles will be alleviated.

As the first pixel electrode 240 and the second pixel electrode 260 may have different display voltages, if the area of the first pixel electrode 240 and the area of the second pixel electrode 260 are appropriately adjusted, different display effects will be obtained. For example, the ratio of the area of the first pixel electrode 240 to the area of the second pixel electrode 260 is from about 2:8 to about 6:4 or from about 25:75 to about 55:45. The practical test shows that when the ratio of the area of the first pixel electrode 240 to the area of the second pixel electrode 260 is about 35:65, a preferred display effect may be displayed. Certainly, the ratio of the area of the first pixel electrode 240 to the area of the second pixel electrode 260 may be different in other embodiment of the present invention to provide a preferred displaying effect.

Furthermore, in the LCD panel, protrusions disposed in the pixel structures may provide appropriate nodes to make the tilt directions of the liquid crystal molecules assume a multi-threshold phenomenon, thus enhancing the wide viewing angle display effect. Herein, the present invention proposes another LCD panel with protrusions disposed therein according to an embodiment. FIG. 3A is a partial schematic top view of a PSA-LCD panel according to another embodiment of the present invention, and FIGS. 3B and 3C are cross-sectional views taken along lines AA′ and BB′ in FIG. 3A respectively. First, referring to FIG. 3A, an LCD panel 300 is substantially similar to the LCD panel 200, and the difference is described as follows. The LCD panel 300 has a plurality of protrusion structures 310 disposed thereon. The protrusion structure 310 disposed on the first pixel electrode 240 is, for example, a spacer 312, and the protrusion structure 310 disposed on the second pixel electrode 260 is, for example, an protrusion 314. Furthermore, the second substrate 220 has, for example, a color filter layer 320 disposed thereon to display multi-color display effect.

Referring to FIGS. 3A and 3B together, the spacer 312 is disposed between the second substrate 220 and the first substrate 210 and located above a part of the first central portions 242a. The spacer 312 is in contact with the second substrate 220 and the first substrate 210 to maintain an appropriate cell gap. The profile of the spacer 312 orthographically projected on the first substrate 210 and the profile of the corresponding first central portions 242a are substantially conformal (as shown in FIG. 3A). The distance d between the edge of the profile of the spacer 312 orthographically projected on the first substrate 210 and the edge of the profile of the corresponding first central portion 242a is about 5 μm to about 50 μm. As the arrangement of the spacer 312 provides a slanted surface for the liquid crystal molecules of the liquid crystal layer 230 to tilt towards the first central portion 242a, the LCD panel 300 has a good display effect. In practice, in order to further improve the display effect of the LCD panel 300, the edge of the spacer 312 projected on the first substrate 210 may be made substantially perpendicular to the tilt directions of the first fine slits 248, so as to make the liquid crystal molecules tilt along the direction of 45°, 135°, 225°, or 315°. Moreover, in order to eliminate the light leakage possibly generated around the spacer 312, the spacer 312 may be disposed above the first capacitor electrode 272.

Furthermore, referring to FIGS. 3A and 3C together, the protrusion 314 is, for example, disposed between the second substrate 220 and the liquid crystal layer 230 and located above the second central portions 262a. The profile of the protrusion 314 orthographically projected on the first substrate 210 and the profile of the second central portion 262a are substantially conformal (as shown in FIG. 3A). Moreover, the distance between the edge of the profile of the protrusion 314 orthographically projected on the first substrate 210 and the edge of the profile of the corresponding second central portion 262a is about 5 μm to about 50 μm. In brief, the arrangement position of the protrusion 314 and the relationship between the protrusion 314 and the second pixel electrode 260 is substantially the same as the arrangement position of the spacer 312 and the relationship between the spacer 312 and the first pixel electrode 240. That is to say, the arrangement of the protrusion 314 contributes to the improvement of the display effect of the LCD panel 300. Furthermore, the protrusion 314 may also be disposed above the second capacitor electrodes 274 correspondingly. Definitely, in other embodiments, the protrusion structure 310 on the first pixel electrode 240 may also be in the form of protrusions, and the protrusion structure 310 on the second pixel electrode 260 may also be in the form of spacers. Or, both of them are in the form of protrusions, or both of them are in the form of spacers.

In view of above, the present invention changes the patterns of the first pixel electrode and the second pixel electrode. Thus, in each pixel structure in the LCD panel, V-shaped main slits are disposed between the electrodes of different display voltages, and the edges of the electrodes on two sides of the V-shaped main slits are parallel. In this manner, the liquid crystal molecules can tilt along the appropriate tilt direction, and thus unnecessary display bright band or color washout will not occur at the slits between the electrodes. Furthermore, the LCD panel of the present invention does not require a shading layer between the first pixel electrode and the second pixel electrode for the unnecessary display bright band. Therefore, the LCD panel of the present invention has a good display aperture ratio and good display effect.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
