Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display, and more particularly to a multi-domain vertical alignment (multi-domain vertical alignment) , MVA) liquid crystal display device. [Prior Art] For the rapid advancement of the multimedia society, most of them have benefited from the dramatic advancement of semiconductor components or display devices. In terms of display devices, Thin Film Transistor Liquid Crystal Display 'TFT-LCDs, which have superior properties such as high quality, good space utilization efficiency, low power consumption, and no radiation, have gradually become the market. Mainstream. At present, the performance requirements of liquid crystal display devices in the market are toward high contrast ratio, n〇gray scale inversion, iittle c〇l〇r shift, and high brightness. Luminance), high color richness, high color saturation, fast response and wide viewing angle. Techniques that currently achieve wide viewing angle requirements include twisted nematic (TN) liquid crystal plus wide viewing film, coplanar switching (in_plane_her_, ips) liquid crystal display devices, margins A fringe field switching liquid crystal display device, a multi-domain vertical alignment thin film transistor liquid crystal display device, and the like. For a conventional multi-domain vertical alignment type liquid crystal display device, liquid crystal molecules can be multi-directional due to alignment protrusions or slits disposed on a color filter substrate or a thin film transistor array substrate. Arranged to obtain a number of different alignment fields (d〇main), so more than 6) 8twf.doc/g 200807110 domain vertical alignment type liquid crystal display device can achieve a wide viewing angle requirement. Despite this, the transmittance of the multi-domain vertical alignment type liquid crystal display device has a different curvature with respect to the gray-scale transmission-level curve as the viewing angle changes. In other words, when the viewing angle is changed, the brightness displayed by the multi-extinguishing vertical alignment type liquid crystal display device changes, which leads to a phenomenon of color shift and insufficient color saturation. At present, the following structure has been proposed to solve the problem of insufficient color shift and color saturation. Figure 1 is a circuit diagram of a conventional halogen unit. Referring to Figure 1, the conventional pixel unit 1 is controlled by the corresponding scan wiring 丨1〇 and the data distribution line I20. Specifically, the active device 13G is electrically connected to the scan wiring no and the data wiring 120. The electrode of the liquid crystal capacitor Clc1 is electrically connected to the active read 130, and the electrode of the liquid crystal capacitor Clc2 is passed through the capacitor 160 and the active device 130. Electrical connection. With such a design, when the voltage is changed, the voltage difference between the upper and lower electrodes of the liquid is higher than the effective laser CLC10 of the liquid crystal molecules corresponding to the liquid crystal capacitance Clc2〇, when the dynamic voltage is input through the (four) wiring (3). CLC2G corresponds to the liquid s eight materials, when the liquid crystal capacitance angle changes, the brightness change can be due to two; the same, however, because the liquid crystal capacitor Clc2 〇 ten to make up the shell and small. The electrode that is electrically connected to the active device 13 is severely delayed when passing through the electrode of the capacitor 160. I, the liquid crystal capacitor Clc2 is inserted into the liquid crystal capacitor Clc20, and the liquid crystal capacitor Clc20 is smashed into a defect of kneading. The voltage obtained by ° will be much smaller than the voltage obtained by the liquid crystal of the capacitor of CLc10. Therefore, the waiter surface may be distorted.

The effect of the ink is different from that of the liquid crystal layer 230 on the second field group D20. Therefore, the brightness change can be changed when the angle of view changes with the viewing angle. It is reduced by the mutual compensation of the first domain group ^D10 and the second domain group D2〇. Moreover, since the first and second pixel electrodes pE1 〇 and pE2 〇 are not floating electrodes, hysteresis or distortion of the picture can be avoided. Hereinafter, a partial top view of a first pixel electrode in an embodiment of the present invention will be described with reference to FIG. In the present invention-embodiment, each of the first pixel electrodes JE10 has a plurality of alignment members sl1. Among them, the alignment member is, for example, a slit. Specifically, the alignment member can be, for example, a slit having a dentate edge as shown in Fig. 7. Of course, the alignment member _ can also be a mineral-free edge slit or an alignment protrusion, which is shown in Fig. 7. The function of these alignment members S10 is to change the electric field in the vicinity, so that the liquid crystal molecules can be in a multi-domain row, and the second electrode element f and/or the common electrode layer can also be used, and an alignment member is also included. For example, slits (such as non-serrated edge slits or serrated edge slits, etc.) or alignment protrusions, so that liquid crystal molecules can be arranged in multiple domains. In summary, in the liquid crystal display device of the present invention, each of the pixel regions is controlled by two active elements to control two halogen electrodes, and the third active element is transmitted through the capacitor and the aforementioned active element. Electrical connection. When the third active component is turned on by the next scan wiring, the voltage of the pixel electrode connected to the electrical m is written through the capacitor, so that the effective voltages on the two denier electrodes are different. Therefore, the tilt angles of the liquid crystal molecules corresponding to the two halogen electrodes in the halogen region will be different, so that the problem of insufficient color shift and color saturation can be solved after mutual compensation.
