Description of the Invention: ~ - Technical Field of the Invention The present invention relates to a liquid crystal display, and more particularly to shielding a power line from a gate line' or It is a dark state light leakage caused by the shadow gate line and the slit in the pixel electrode to improve the contrast of the liquid crystal display. [Prior Art] LCD (Liquid Crystal Display) has two glass substrates (or generally referred to as substrates) and two glass substrates are placed facing each other and have a liquid crystal layer ) is disposed between two glass substrates. Liquid crystal displays in a vertically aligned mode utilize a negative liquid crystal material and a vertically aligned film. When no voltage is applied to the liquid crystal display, 'the liquid crystal molecules in the liquid crystal layer are aligned in the vertical direction (this vertical direction is relative to the main surface of the glass substrate), so that the incident light source cannot penetrate the vertical liquid crystal display, resulting in the so-called. Dark display. Conversely, when a voltage is supplied to the liquid crystal display, the liquid crystal molecules in the liquid crystal layer are arranged in the horizontal direction, and the incident light source can penetrate through the vertical liquid crystal display' to cause a white display. However, when at an angle other than the display area, the user can perceive a reduction in display contrast in the vertical alignment type liquid crystal display. This causes interaction of liquid crystal molecules in the liquid crystal display. When the light source passes through the liquid crystal display state %' in one direction, the incident angle of the light source is not a right angle, and therefore, the liquid crystal molecules of the light source and the liquid crystal layer exert a different effect from the liquid crystal display whose light source is at an incident angle at a right angle. Therefore, when the light source is not at an angle of incidence, there is a significant difference between the light penetration (Ught 7 September 23, transmissive state) and the non-penetrating (dark state) contrast state. . This makes the vertical alignment LCD display unsatisfactory in many display screen applications, such as flat-panel TV displays and large computer displays. Large viewing angles can be applied to multi_d〇main vertical alignment. Vertical alignment type liquid crystal display in multiple display fields

liquid crystal molecules in the pixels of each side in a plurality of different directions. In some traditional MVALCDs, multiple display domains are used to improve the performance of displays at different viewing angles. In general, the 'multiple display domain vertical alignment system is composed of a plurality of slit electrodes in a pixel electrode in a thin film transistor sub-channel and a common electrode on a color filter substrate. Most of the protrusions on the element are formed as 'these protrusions and slits are arranged in a staggered manner. The alignment of the liquid crystal molecules is related to the edge regions created by the projections and the pattern of the slits. Fig. 1A is a view showing the structure of the port of the slit and the port adjacent to the slit of the gate line. Fig. m is a schematic sectional view showing the structure of the port of the slit.

Fig. 1A shows a cross-sectional area 15 〇 between the gate line 112 and the slit 142 of the pixel electrode 140 in a general liquid crystal display, due to the application of a voltage, by the gate The electric field (or power line) generated by the line 112 causes a light leakage phenomenon from the staggered area 15 〇 or the notch of the narrow sipe 142 of the pixel electrode 140, so that the contrast of the liquid crystal display is lowered. According to the above, how to improve the design of the pixel electrode adjacent to the gate line and the slit junction in the pixel electrode to avoid dark light leakage caused by the intersection of the pixel electrode and the slit of the power line (or electric field) Into one Effectively improving the contrast of the liquid crystal display has become a very important issue in the process of the liquid crystal display.

The gate line and the data line are alternately arranged to define a pixel. The region 'and the thin film electricity Ba|f4 are disposed in the pixel region and electrically connected to the interpolar line and the data line. The pixel electrode is disposed in the pixel region and electrically connected to the thin film transistor, and has at least one at the pixel electrode The slit ❻ is also a port of the slit close to the gate line.

The replacement page on September 23, 100 makes the comparison of the liquid crystal display relatively as described above. The invention discloses a light leakage caused by the end σ of the slit by the region of the father of the gate line covering the gate line and the slit. Therefore, 1 is higher than the liquid crystal display H disclosed in the prior art. Increasing the contrast and improving the reliability and display quality of the liquid crystal display. The present invention is described in detail below with reference to the preferred embodiment of the present invention. (For the purpose, structure, features, and the like of the present invention The function is further described below, and is described in detail below with reference to the embodiments.) [Embodiment] The present invention discloses a liquid crystal display for improving contrast, which aims to conceal the end of the slit of the gate line and the pixel electrode. The junction of the junction to further reduce the light leakage between the gate line and the port at the slit of the money, further enhances the contrast of the liquid crystal display. Fig. 2 is a schematic view showing a pixel region of a vertical alignment liquid crystal display H according to the contrast enhanced liquid crystal display disclosed in the present invention. Wherein, the shielding layer is disposed at the periphery of each of the pixel regions.

In this embodiment, the liquid crystal display includes: a first substrate (not shown), a second substrate (not shown), and a liquid BB layer disposed between the first substrate and the second substrate (not in the Shown in the figure). In this embodiment, the first substrate may be a color filter substrate. The second substrate may be a TFT array substrate. The first substrate and the second substrate face each other. And in the subsequent combination of vertical alignment. A spacer (not shown) is further included between the first substrate and the second substrate to define a gap between the two substrates. In this example, a gate line (gate 1^) 320 and a data line (data lme) (not shown) are disposed on a substrate, and on the second substrate, by the gate line 320 and The data lines are interleaved to define a pixel area ^pixei regi〇n) (not shown in the figure). In addition, a thin film transistor (not shown) is disposed on the second substrate, which is disposed in the pixel region and electrically connected to the gate line 320 and the data line. The pixel electrode (9) is disposed in the pixel region and electrically connected to the thin film transistor. Here, the pixel electrode Mo is composed of indium tin oxide (IT0). The above structure is well known to those skilled in the art and will not be described again. In this embodiment, the pixel electrode 330 has at least one slit 34 〇, and the port of the slit 340 is adjacent to the gate line 32 〇. In addition, in this embodiment, a shielding layer 360 is further disposed on the first substrate, and the I1 material adjacent to the port 342 of the slit 340 is replaced by the page 9 on September 23rd. The P-brake gate lines 320 are mutually overlapped, that is, the overlapped products in the figure 1 ^ shield layer 360 is used to shield the gate line 320 and the slit 340 end of the parent boundary to block the power line dispersion generated here because of the gate line 32〇 Light leakage that leaks into the slit 34G of the pixel electrode 330. Therefore, the vertical alignment type liquid crystal display can be shielded when it is operated, when the voltage is applied, at the end σ 342 of the slit 34 of the pixel electrode 33, which is caused by the light leakage generated by the gate line 32 (). Layer 360 is shielded to maintain contrast of the liquid crystal display and maintain the display quality of the liquid crystal display. It should be noted that the shielding layer 360 disclosed in this embodiment may be a black matrix layer (the metal layer above the gate or the gate line), and is preferably disposed on the array substrate (ie, the second layer). Further, in the embodiment, a color filter layer (not shown) is further disposed on the first substrate above the pixel electrode 330 in the pixel region. And a protrusion (not shown in the figure) is further disposed on the first substrate, and is disposed in a staggered manner with the slit 34, and the surface is opposite to the pixel electrode 330. FIGS. 4 and 5 are the present invention. The other two preferred embodiments of the present invention are the same as the first preferred embodiment in the following embodiments. Therefore, the same parts are referred to for comparison, and are not described herein. Please refer to FIG. 4, the present invention.

In this embodiment, at the first - At least one color filter layer (not shown in Table 12 1356231, at least one eleetn) deK unmasked layer (not shown in the figure) is disposed on the board, and the mask layer includes a black matrix layer. The substrate further includes a protrusion (not shown) disposed on the first substrate in a parallel manner, and the second substrate includes at least: a gate line 42〇, a data line (not shown in the figure) a thin film transistor (not shown) and a pixel electrode 430. wherein 'the data line (not shown) and the gate, the lines 420 are arranged in a staggered manner to decipher at least one pixel area (not in the The thin film transistor (not shown) is disposed in the pixel region, and is electrically connected to the data line and the gate line. The pixel electrode 43 is disposed in the pixel region, and is electrically connected. Connected to the thin film transistor, having at least a slit 4 s in the pixel electrode 43 ,, and one end □ 442 of the slit is adjacent to the gate line 420 , wherein the gate line 42 〇 has a gate line notch 422 ′ Line notch 422 is adjacent to port 442 of slot 440. In this embodiment The length of the slit 440 of the pixel electrode 430 (the distance from the notch 422 of the gate line 420 to the slit 440 of the pixel electrode 430) can be increased by the gate line notch 422 generated at the gate line 420. And reducing the gate line width of the slit 440 adjacent to the pixel electrode 430, that is, as shown in FIG. 4, when the gate line 420 leaks light, the length of the slit 440 is increased and the pixel electrode 430 is reduced. The width of the gate line 420 near the slit 440 is such that the portion of the gate line 420 adjacent to the pixel electrode 430 is reduced, so that the distance between the gate line 42 and the electric field or power line that leaks to the pixel electrode 430 via the slit 440 is also opposite. Increasing the electric field or power line that the relative gate line 420 leaks to the pixel electrode 430 via the slit 440 is reduced. Therefore, it is also possible to reduce the light leakage caused by the electric field of the gate line 420 near the port 442. 1356231 Next, please refer to the fifth page, the private secrets of the 丄 丄 9 9 9 9 9 9 9 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 〜 根据 根据 根据 根据 根据 根据The red display includes at least an earth plate (not shown in the figure), a second substrate (not shown in the figure), and a liquid crystal layer diagram t, which is disposed between the first substrate and the second substrate. , the ', there are y color 遽 詹 詹 (not shown in the figure), the common electrode (not shown in the figure f) and the shielding layer (not shown in the figure).
