摘要： A reflection member applicable to a liquid crystal display device is disclosed. The liquid crystal display device includes a reflective pixel electrode 19 formed on a matrix array substrate 11, a counter electrode provided opposite to the reflective pixel electrode 19 on a counter substrate 22, and a liquid crystal layer 27 held between the reflective and counter electrodes 19 and 25. The reflective pixel electrodes 19 have convex and concave portions 20a and 20b as light scattering elements. Centers of the convex portions 20a are disposed in lattice points of hexagonal lattices. Lattice parallel vectors are rotated around the radius center by an angle of about 60°, defined between the lattice points at both end portions of the pixel electrode, but, more suitably, the one ranging from 51.4° to 68.6°, i.e., 60°±8.6°. Such disposition of the light scattering elements reduces two dimensional periodicity as to the convex portions. Thus coloring caused by optical interference between the convex portions 20 can be suppressed. Excellent display quality with uniform brightness is achieved by making distances between the light scattering elements consistent with those from which a optimal slant angle distribution can be obtained.

摘要： Each pixel electrode is connected to a signal line and a scanning line through a TFT while at least part thereof overlaps the signal lines. A plurality of shield electrodes having electrostatic shielding characteristic extend from an auxiliary capacitance line, which extends perpendicular to the signal lines, each along the signal line. Each shield electrode has a first electrode portion arranged to overlap only a side edge portion of one of two adjacent pixel electrodes and a side edge portion on a side of one pixel electrode of the signal line side edge portions, and a second electrode portion arranged to overlap only a side edge portion on the other pixel electrode. An overlapping width between the shield electrode and pixel electrode is larger than the overlapping width between the signal line and pixel electrode.

摘要： Not only a signal line (27a) but also an adjacent signal line (27b) partly oppose a reflection pixel electrode (50a) through an insulating film to be capacitively coupled to the electrode. The area of that portion (27a1) of the signal line (27a) which opposes the reflection pixel electrode (50a) is almost equal to that of that portion (27b2) of the signal line (27b) which oppose the pixel electrode (50a). Therefore, the influence of the signal potential of the signal line (27a) on the reflection pixel electrode (50a) through capacitive coupling is nearly equal to that of the signal potential of the signal line (27b) on the reflection pixel electrode (50a) through capacitive coupling. Luminance differences between adjacent pixels (50a and 50b; 50b and 50c, . . . ) are reduced, thereby preventing crosstalk.

摘要翻译： 不仅信号线（27a），而且邻近的信号线（27b）部分地通过绝缘膜与反射像素电极（50a）相对电容耦合到电极。 与反射像素电极（50a）相对的信号线（27a）的部分（27a1）的面积大致等于与像素电极（50a）相对的信号线（27b）的部分（27b2）的面积， 。 因此，通过电容耦合，信号线（27a）的信号电位对反射像素电极（50a）的影响与反射像素电极（50a）上的信号线（27b）的信号电位的影响几乎相等， 通过电容耦合。 相邻像素（50a和50b; 50b和50c之间的亮度差）减小，从而防止串扰。

摘要： In an electrode substrate used in a liquid crystal display device, a contact hole for connecting a signal line to a drain electrode of a pixel thin film transistor is provided in a position overlapping a pixel electrode in order to improve yields by reducing a short circuit between adjacent pixel electrodes. With this configuration, the contact hole does not exist at a boundary between the two adjacent pixel electrodes. Accordingly, the pixel electrodes do not suffer an influence of an electrode material remaining at a recess of the contact hole, and a short circuit between the adjacent pixel electrodes can be thereby prevented.
