Abstract: In each pixel region of a liquid crystal panel of an in plane switching mode, a pixel electrode is made to have a two-layer structure composed of a lower pixel electrode located in the same layer as a signal line and of an upper pixel electrode located in the same layer as a common electrode. Moreover, an electrode portion of the lower pixel electrode is made closer to the signal line than the upper pixel electrode. Furthermore, the signal line, a gate line and the common electrode are arranged in an overlapped manner.

Abstract: A liquid crystal display, and its manufacturing process, are provided in which antistatic measures are taken in the manufacturing process to prevent the occurrence of static failure before the formation during that process of the short ring. On a glass substrate 2, gate lines 46 are formed. The gate lines 46 are disconnected to form a discharge gap 50 with projections 52 and 54 on both sides of the gap 50. The discharge projections 52 and 54 are positioned substantially at the center of the edges of the disconnected portion of the gate lines 46. A gate insulation film 56 is formed on the gate lines 46 and in the discharge gap 50. Two through holes 58 are made in the gate insulation film 56 in the vicinity of the discharge projections 52 and 54 of each gate line 46. A metal wiring layer 48 is formed on the gate insulation film 56 so as to fill in the through holes 58 where the discharge gap is no longer necessary.

Abstract: To prevent the damage of a display device by static electricity and to drive the display device with low voltage, on a transparent substrate of a liquid crystal display, two short circuit wires are provided, connected via a resistance. Each of the data lines is connected to the one short circuit wire via a first switching circuit, whereas each of the gate lines is connected to the other short circuit wire via a second switching circuit. A switching circuit is turned on when the potential difference between a data line and the one short circuit wire or the potential difference between a gate line and the second short circuit wire exceeds a predetermined value. When images are displayed on a liquid crystal display, the average voltage applied to each of data lines is applied to the first short circuit wire and the average voltage of voltages applied to each gate line is applied to the second short circuit wire to turn on the switching circuits.

Abstract: The present invention relates to the improvement in the frame area of the liquid display panel of a liquid crystal display device, and its object is to provide a liquid crystal display device which is enhanced in its blocking ability and the ability of the blocking area to prevent electrostatic failure. A blocking layer 12 is formed in a frame area 1 on TFT array substrate 3. The edge portions of the blocking layer 12 have overlapping areas 14 overlapping the edge portions of each of data lines 10, which are metal layers, with predetermined overlaping margin d as viewed from a direction perpendicular to the surface of the TFT array substrate 3. An insulation layer 16 is formed on the blocking layer 12 and the TFT array substrate 3. On the insulation a semiconductor layer 18 is formed. A plurality of data lines 10 is disposed on the semiconductor layer 18.

Abstract: A liquid crystal display apparatus in normally-white mode in which gray scale display is obtained by providing different applied voltages corresponding to different gray scale levels, respectively, characterized in that in a curve showing the relationship between the applied voltage and light transmittance, the lowest applied voltage is set so as to be shifted in the direction of a monotonically decreasing region of the curve. The display simultaneously provides both good contrast ratios and good gradation at large viewing angles, and gray scale is not inverted.
