When a voltage is applied to the transparent electrode 108 of the upper plate ιοί and the halogen electrode 1〇5 of the lower plate 1〇2, so that the pixel voltage is between the upper plate 101 and the lower plate 1〇2, the liquid crystal layer 1 0 9 The arrangement of the liquid crystal molecules will change with the size of the pixel voltage, and the light transmittance (ligM transmissivity) of the liquid crystal molecules in the halogen will change with the arrangement of the liquid crystal molecules. Therefore, the liquid crystal panel can be made to have different brightness by controlling the voltage of the pixel applied to the upper plate 1 〇 1 and the lower plate 1 〇 2 .

According to the arrangement of the liquid crystal molecules in the liquid crystal panel, the liquid crystal panel can be roughly divided into a twisted nematic mode (TN) and a vertical alignment mode (VA). Please refer to section 2A~2B

—^ Case No. 90131164 V. INSTRUCTIONS (4) The twisted nematic liquid crystal panel is fully illuminated in the passive state, and is completely dark in the main ^. When the liquid crystal panel displays the surface, most of the inspection states do not need to display high brightness. Especially when the computer enters the sleep mode ("Μ-素都mode", or 疋 screen protection mode, most of the books on the panel are dark. If a twisted nematic liquid crystal panel is used, it will take more = force. In addition, when the twisted nematic liquid crystal panel is in an active state, 'liquid crystal eight' will have a birefringence effect, so that a few 刀^ cut lines can still penetrate the liquid crystal panel. Therefore, the brightness of the twisted nematic liquid crystal panel is reversed. The contrast ratio is poor, which also affects the quality of the image. As described above, by controlling the magnitude of the pixel voltage applied to each pixel, the arrangement of the liquid crystal molecules in the pixels is changed, thereby making each element Different brightness is displayed. However, when the liquid crystal panel looks at the surface, the voltage of each pixel of the two elements is not the same. When the adjacent two elements have different = small pixel voltage, then the two pixels There is a transverse electric field adjacent to the edge, and the electric field strength is proportional to the difference between the two adjacent halogen elements. The liquid crystal molecules near the edge of the two halogen edges are affected by the transverse electric field. The irregular arrangement is produced. In this way, the brightness at the edge of the pixel is different from the expected, and even black stripes are generated, thus affecting the development quality of the liquid crystal panel, which is called the fringe effect. Eliminating the edge effect is a major problem that the liquid crystal display technology is currently to be solved. [Invention and Summary] In view of the above, an object of the present invention is to provide a liquid crystal display panel having the following advantages: 1 · Inter-process process 'Special It is to reduce the use of friction processes.

2 · Improve the brightness contrast of the LCD panel. 3 · Save power consumption of the LCD panel. 3) avoiding the edge of the halogen element to be transversely according to the purpose of the present invention, the lower plate of the LCoS and the upper plate and the liquid crystal layer, wherein the surface direction of the upper plate is included. The lower plate alignment film is formed, wherein each of the halogen and the two halogen electrodes is a groove-phase inclined surface and a second inclined surface, and the groove direction is parallel. Each of the protrusions is provided with an alignment film system disposed on the halogen electrode group. In order to clarify the above objects of the present invention, a preferred embodiment will be described as follows: Effect on the electric field. A reverse-based nematic liquid crystal panel (Uquid) comprising: an upper plate, and an upper surface The λ composed of the liquid crystal molecules between the plate and the I plate is provided with an upper plate alignment film, and has an indicator electrode group, and the plurality of protrusions and the electrode group are composed of two halogen electrodes. Wherein, the groove has an opposite relationship between the first major axis system and the upper plate alignment film between the two pixel elements, the lower plate and the large object. , features, and advantages can be more obvious and in conjunction with the drawings, for details. [Detailed Description of the Invention] The technical feature of the present invention is that two halogen electrodes are used as a single element electrode group. The two halogen electrodes of the electrode group are separated by a spacing. A protrusion (pr〇i: rusion) is formed between the pixel group and the adjacent element group. Further, the alignment film on the upper plate forms an indication direction parallel to the long axis of the groove. Thus, the liquid crystal panel is an inverse twisted nematic liquid crystal panel.

1289697 ^ V. INSTRUCTION DESCRIPTION (6) Fig. 4A of a buckwheat photograph showing a plan view of the arrangement of the plate halogen electrodes under the solar cell panel according to the first embodiment of the present invention. The pixel electrodes on the liquid crystal panel (for example, the pixel electrodes 401, 402, 403, and 404) are grouped into groups to form a halogen electrode group. (For example, the pixel electrodes 4 〇 1 and 4 〇 2 are the denier electrodes). The two halogen electrodes of the parent-halogen electrode group have a groove (for example, grooves 405, 406), and the halogen electrode There are protrusions (for example, protrusions 4〇7, 408 and 4〇9) between the group and the halogen electrode group. It should be noted that, for the convenience of explanation, the reflective layer and the alignment film disposed on the pixel electrode are not shown in the figure. Please refer to FIG. 4B, which is a cross-sectional view taken along line AA of FIG. 4A. In Fig. 4B, only the halogen electrode group composed of the halogen electrodes 40, 402 is taken as an example to illustrate the influence of the protrusions 4?7, 408 and the trenches 405 on the liquid crystal molecules. On the ruthenium substrate 41 G, there are separated pixel electrodes 4 〇 1, 40 2 to form a pixel electrode group. The halogen electrode group and the other halogen electrode groups are separated by protrusions 407 and 408, and the halogen electrode 401 and the halogen electrode 4〇2 are separated by a groove 405. The height of the protrusions 407, 408 is higher than the height of the halogen electrodes 401 and 402, and the depth of the trench 405 is sufficient to block the pixel electrodes 401 and 402 without being coupled to each other. The pixel electrodes 4〇1, 402 and 403 are over a reflective layer (not shown in the figure), and the alignment film (not shown) covers the halogen electrodes 401, 402, 403, the reflective layer, Overhangs 407, 408 and trenches 405. It should be noted that in the present invention, the alignment film of the lower plate does not need to form an indicating direction. In this way, the steps of the process can be simplified. At the same time, it can also avoid the uneven film in the process of the rubbing process of the lower plate, and it will not generate electrostatic discharge due to the rubbing process, or because II 1 is a national circle ϋΙ·· III Ηιΐϋϋ__ TW0597(060706)CRF.ptc Page 10 1289697 Case No. 90131164 Correction of the fifth day of the invention. (7) The surface of the lower plate is left with impurities, causing scratches on the alignment film. Referring again to Figure 4B, the shape of the section of the projections 4, 7, 408 is approximately triangular. The protrusion 408 is taken as an example, and the protrusion 408 has a left side surface 411 and a right side surface 412. Due to the alignment film, the liquid crystal molecules adjacent to the protrusions 408 on both sides of the protrusion 408 will be inclined toward the sides of the protrusions 4〇8, respectively, and arranged in a manner perpendicular to the surface of the protrusions 408. Thus, the alignment directions of the liquid crystal molecules are not perpendicular to the lower plate 422, but have a pretilt angle. Further, the liquid crystal molecules in the vicinity of the left side surface 411 and the right side surface 41 2 of the protrusions 4〇8 are arranged in the vertical left side surface 411 and the right side surface 412, respectively, and have pretilt angles in different directions, as shown in the first figure. It should be noted that, in the case of the protrusions 4〇8, the protrusions 4〇8 are formed between the halogen electrodes 402 and 403, except that the liquid crystal molecules near the protrusions 4〇8 have a pretilt angle, and more importantly, It can reduce the influence of the horizontal electric field formed by the difference of the pixel voltage between the pixel electrodes 402 and W3, and reduce the irregular arrangement of the liquid crystal molecules of the edge electrodes 4〇2 and 403. Solve the edge effect of the pixels caused by the traditional method to improve the imaging quality of the liquid crystal panel. Theoretically, the higher the height of the protrusion, the stronger the thrust applied to the nearby liquid crystal molecules, and the arrangement of the entire halogen liquid crystal molecules. The greater the influence, but the higher the height of the protrusion, the lower the yield when the process is performed. The height of the protrusion of the present invention is at least one-fifth of the distance between the upper plate and the lower plate, One-third of the distance between the upper and lower plates is optimal. In addition to the size of the protrusions, the material of the protrusions also affects the protrusions.

Low 9Q1311R4 V. Inventive Note (8) The protrusion of dielectric constant has a strong thrust to the nearby liquid crystal molecules, because the material of the protrusion is preferably a material with a low dielectric constant. For example, cerium oxide (silic 〇n di〇xid (eight) or other dielectric constant with a dielectric opening of 3.9, a material similar to a material. Generally, a material having a dielectric constant of 10 or less can be used to form a canine. The good result of the invention. Referring again to Fig. 4B, the trench 4〇5 is taken as an example, and the trench 4〇5 has a left oblique=13 and a right slope 414. Due to the alignment film, no voltage is applied In the electrodes 401, 402 and 403, the liquid crystal molecules adjacent to the trenches 4〇5 on both sides of the trench 4〇5 will be inclined to the sides of the trenches 4〇5, respectively, and arranged in a manner perpendicular to the surface of the trenches 04. If &, the liquid crystal molecules are arranged in a direction that is not perpendicular to the lower plate 42 2 and has a pretilt angle, and the liquid crystal molecules in the vicinity of the left side surface 413 and the right side surface 414 of the groove are respectively The right side surface 414 is arranged in a different manner, and has different inclination angles, as shown in FIG. 4B. The J top needs to pay attention to S, taking the groove 405 as an example, the liquid crystal molecules in the groove 405 on both sides of the groove 4〇5 will be respectively Tilting to both sides of the trench 4〇5. The liquid crystal molecules on both sides of the trench 405 are very close to each other and have a difference In the oblique direction, the liquid crystal molecules on both sides of the trench 405 will affect each other, and push each other to be inclined in a direction parallel to the long axis of the trench. The oblique direction of the liquid crystal molecules is perpendicular to the paper surface, which may be the direction of the vertical paper ( It can also be the side of the vertical paper facing down)

Since the tilt direction of the liquid crystal molecules in the vicinity of the groove is inconsistent, the shadow liquid will be: The brightness of the edge of each pixel on the panel, and the generation of the singular point. Bu from the ^ molecule randomly and independently select the other two liquid crystal molecules in each of the four liquid crystals, and the other liquid crystal molecules in the halogen, and the ::;::, will also affect the input of the halogen voltage to drive each element.

The present invention provides protrusions 407, 408 on the surface of the lower plate 422, and the direction of the alignment film of the upper plate 420 is parallel to the long axis of the groove. The direction of the liquid crystal molecules between the upper plate 420 and the lower plate 422 is arranged in a reverse twisted nematic manner. Please refer to FIGS. 5A to 5b, which respectively show the reverse twisted nematic liquid crystal panel.

DESCRIPTION OF THE INVENTION (10) When the pixel voltage is not supplied, the liquid crystal molecules are arranged in a direction perpendicular to the upper and lower plates except for the liquid crystals near the protrusions and the grooves, such as As shown in Fig. 5A, at this time, the liquid crystal molecules have a low light transmittance, and the brightness of the halogen is completely dark. When a sufficiently large halogen voltage is supplied, the protrusions and the grooves close to the % plate are received. The liquid crystal molecules of the pretilt angle, and the alignment film of the alignment film close to the upper plate, according to the direction of the liquid crystal molecules arranged therein, the liquid crystal molecules 50 0 are twisted from the lower plate alignment film 502 to the upper plate alignment film 5〇4 (twisted) ) 90 degrees ' as shown in Figure 5B. At this time, the liquid crystal molecules 5 00 has high light transmittance, and the pixel brightness is full bright. The reverse twisted nematic liquid crystal panel is completely dark in the passive state and fully bright in the active state. Thus, the conventional twisted nematic liquid crystal panel can be solved. A lot of power, and the poor contrast of brightness contrast (c〇n1;rast rati〇)' to improve the development quality of the liquid crystal panel. The vertical eye refers to the 6A~6C figure, which shows the pixel group and the groove In the same pixel group, the two adjacent pixels in the lateral direction are separated by grooves. Each of the pixels adjacent in the longitudinal direction, for example, the halogen electrode groups 6〇2 and 604 are separated by a groove 60 5 . The protrusions 6〇6 in the pixel group 6〇2 and the protrusions 607 in the element group 604 are also separated by the grooves 6〇5. The edge of the protrusion 6〇ϋ6^7 may be aligned with the groove 6〇5, as shown in Fig. 6 , or the groove 605 may be protruded, as shown in Fig. 6, or the protrusions 606 and 6 The edge of the crucible 7 is recessed on the side of the groove 605 as shown in Fig. 6C. The arrangement of the halogen electrode groups on the Shi Xiji LCD panel is not limited to the fourth:: arrangement. Referring to Figure 7, there is shown a plan view of a lower plate of a ruthenium-based liquid crystal panel in accordance with a second embodiment of the present invention.

The polar group is staggered with the next row of paraphernized electrode groups. For example, in Fig. 7A, the halogen electrode group 70 2 is arranged in a staggered arrangement with the pixel electrode groups 7〇4, 7〇6. Fig. 7B is a plan view showing a lower plate of a liquid crystal liquid crystal panel according to a third embodiment of the present invention. When the halogen electrodes 7〇8 are arranged in a diamond shape, it is also possible to use the structure of the groove and the protrusion while using the present invention. The 矽-based 矽-based liquid crystal panel with a diamond arrangement is applied to a projection TV to produce better picture quality.突起 The size and shape of the protrusions and grooves can be designed in a variety of ways. Please refer to Figures 8A-8C for a schematic view of protrusions and grooves of different shapes. In Fig. 8A, the two sides of the trench 802 are respectively composed of two slopes of different slopes. In Fig. 8B, a portion of the side of the protrusion 804 may be covered by the halogen electrodes 806 and 808. In Fig. 8C, the depth of the trench 81 may be greater than the height of the pixel electrode 812. A portion of the germanium substrate 81 4 can be etched using a yellow light process to obtain a trench 8 that is deeper. As such, the sides of the grooves 810 may be more inclined slopes. It is within the scope of the present invention to combine a groove and a protrusion which are capable of achieving a pretilt angle effect of liquid crystal molecules close to the groove. Please refer to FIG. 9, which is a cross-sectional view of a bismuth-based liquid crystal panel in a fourth embodiment of the present invention. If the trench 902 between the two halogen electrodes on the germanium-based liquid crystal panel is filled with the insulating material 904. Then, the protrusion 906 is disposed at the lower side and the indication direction of the upper plate alignment film is appropriately set. The effects of the present invention as described above can still be achieved. The present invention is not limited to being implemented only in a ruthenium-based liquid crystal panel. A liquid crystal display (LCD) can also be fine. The difference between the liquid crystal display panel and the Shi Xiji LCD panel is that the lower panel is a page 15 Case No. 90131164 Λ_Ά 曰

TW〇597(〇6〇7〇6)CRF.ptc No. 16' except that it is possible to form a transverse electric molecular arrangement that does not cause the pixel to be reverse twisted. So, more power, imaging quality. It is a better practice to use this technique for a variety of applications. Patent Application No. 1289697 V. Inventive Note (12) A glass substrate instead of a germanium substrate. And the lower plate groove is blocked. The effect of the present invention can be appropriately set by fitting each of the two phase groups 'each of the halogen electrode groups in a protruding manner. [Effect of the Invention] The alignment film of the lower panel of the panel disclosed in the above embodiment of the present invention does not require a step of forming a process. At the same time, it can avoid the occurrence of unevenness in the process of 'unevenness', or the scratch on the surface of the lower plate. In addition, in addition to providing a pretilt angle on the lower plate, it is more important to reduce the liquid crystal at the edge of the pixel electrode due to the difference in the voltage of the halogen. This will effectively solve the conventional method and liquid crystal of the present invention. The display panel is completely dark when it is bad, and it is a disadvantage that the full steering column type liquid crystal panel is inferior in the active state, so as to improve the liquid crystal panel, although the present invention is not intended to limit the present invention, the present invention Within the spirit and scope, when the protection range of the present invention can be modified, it is not necessary to form a halogen element between the adjacent pixel electrodes and the other elemental electrode groups. The direction of the film can also be displayed in the reverse twisted nematic liquid crystal display direction. In this way, the alignment film of the board can be simplified in the rubbing process, and no impurities are left in the rubbing process, which causes the liquid of the alignment film to be close to the protrusions to reduce the problem of the shadow rule caused by the surface of the halogen electrode. Such as edge effects. The column type, in the passive shape, can solve the traditional twist and the brightness is compared to the above. The example is that the artist does not deviate from the movement and retouch, so the definition of the enclosure is 1289697. Case No. 90131164 Λ_R Correction
