Description of the Invention (2) [Problems to be Solved by the Invention] In such a liquid crystal display device of the transverse electric field method, when the display surface is weighted, display defects occur due to abnormal alignment of the liquid crystal around the weighted portion, and After the weight is removed, the problem of the so-called weighted trace that has poor display and can be recognized for a long time occurs. The principle of the occurrence of weighted traces will be described using Figs. Fig. 11 shows a state where no voltage is applied to the liquid crystal, and Fig. 12 shows a state where voltage is applied to the liquid crystal; Fig. 13 shows a state where voltage is applied to the liquid crystal and is weighted; Fig. 14 shows a state where voltage is applied The liquid crystal molecules are aligned to the liquid crystal and in a state after deweighting. As shown in FIG. 11, in a state where no voltage is applied to the liquid crystal, the liquid crystal systems are aligned side by side by an orientation direction determined by a liquid crystal alignment method such as rubbing. In the direction of the electric field. At this time, as shown in FIG. 12, at the end of the pixel electrode 10 or at the opposite electrode ^ end, due to the change in the direction of the electric field, the area where the liquid crystal reverses will occur, and the orientation will occur in the boundary with the area I forward. Anomaly area 22. In the voltage applied state and the constant voltage state, the misalignment region can hardly be recognized because it only occurs near the electrode end. However, when the display surface is weighted under the applied voltage state, as shown in FIG. 13, the phenomenon that the abnormal alignment region 22 at the end of the pixel electrode 10 and the abnormal alignment region 22 at the end of the opposite electrode 11 expands. 'And the misorientation area 22 will be recognized. Most of this directional abnormal area 22 will return to its initial state after the weight is removed, but a part of it will be identified due to long-term persistence, as shown in Figure 14, which will significantly reduce the display quality. In addition, in Figures 11 to 14, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied to the paper size of the liquid crystal in the orientation direction. 311629 — — — III! —! — ·-I Snow II t · Ι!

Description of the invention (3) Display the situation where the source wiring 12 rotates counterclockwise, and the orientation of the liquid crystal The case where the direction is clockwise relative to the source wiring 12 is shown in Figs. 15 to 17. Fig. 15 shows a state in which a voltage is applied to the liquid crystal; Fig. 16 shows a state in which a voltage is applied to the liquid crystal and has a weighted 2 state; and Fig. 17 shows a state in which the voltage is applied to the liquid crystal and the state after the weight is $ Molecular arrangement. In this way, the location of the liquid crystal on the source wiring 丨 2 | | The direction where the clockwise clockwise rotation occurs in the abnormal position region 22 of the device and the location where the abnormality occurs is opposite to the source wiring 12 Line symmetry. Of the methods for reducing the aforementioned weighted traces, a method of increasing the angle of friction is generally known. However, in the transverse electric field method, because the viewing angle direction with a relatively high contrast is the friction angle direction, that is, the orientation direction of the liquid crystal and the direction at right angles to it, when the friction angle is increased, the display device moves up, down, left, and right The problem of reduced viewing angle characteristics. In addition, since the driving voltage increases as the friction angle increases, a problem that it is difficult to perform low-voltage driving also occurs. The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to obtain a wide range of display defects caused by weighting the display surface, which can reduce the so-called weighted trace defects that can be recognized for a long time after the weight is removed, and has a wide width.

Description of the invention (14) As stated above, according to the present invention Since it is at the front end portion of at least one of the pixel electrode and the opposite electrode, the orientation of the pixel electrode or the opposite direction of the liquid crystal to the direction of the image signal is bent, so the pixel electrode or the front end portion of the opposite electrode can be bent. The direction of the electric field is controlled to the direction that the liquid crystal is to rotate, and since the liquid crystal rotated in the reverse direction can be quickly returned to the forward rotation direction by using weighting, the display failure caused by weighting the display surface can be quickly reduced. The poor quality of the so-called weighted traces of time recognition improves display quality. Furthermore, since a protective plate for preventing weighting of the display surface is not required, there is an effect that the manufacturing cost of the liquid crystal display device can be reduced.
