摘要： A liquid crystal display has an increased aperture ratio achieved by an increased area surrounded by the pixel electrode in a pixel area. However, this may result in poor image quality due to the excited interference voltage that is generated by parasitic capacitance created by the overlap of the pixel electrode and the data lines. At different portions of the data lines, the area of overlap between the pixel electrode and the data lines are different. Thus, to eliminate the excited interference voltage and enhance image quality, the thickness of the dielectric member between the pixel electrodes and the data lines is different so that the parasitic capacitance of the parasitic capacitors is about the same.

摘要： A Thin Film Transistor (TFT) array substrate has a dummy signal line as a short circuit wiring for preventing a short circuit due to electrostatic breakdown between a signal line as an upper layer wiring and a gate line as a lower wiring. The dummy signal line is formed on an outer peripheral area of the TFT array substrate. This dummy signal line has a three-layer structure of a silicon lower layer, an Indium Tin Oxide (ITO) intermediate layer and an aluminum (Al) upper layer, enumerated from the lower layer. Although the silicon layer is formed as one consecutive wiring during formation thereof, the silicon layer is etched simultaneously with the Al layer when the Al layer is subjected to pattern forming, and is electrically disconnected between the gate lines. Since the dummy wiring is disconnected after its formation, a short circuit does not occur between the gate lines even in the case where the dummy wiring and two or more of the gate lines are short-circuited with each other.

摘要： An active matrix type liquid display includes a main display and a sub-display having pixel areas. The pixel areas in the sub-display are different in size from the pixel areas in the main display. The active matrix type liquid display is configured so that the ratio of minimum space to maximum space is equal to or greater than one. The minimum space is the distance that separates the nearest ends of one pixel electrode and one gate electrode. The maximum space is the distance between opposite surfaces of paired electrodes.

摘要： In a TFT array substrate 10 of an electrooptical device, a scanning line 3a, a drain electrode 11, a first light shield layer 13, and a data line 3a are laminated over a channel region 1a′ of a TFT 30 and a second light shield layer 14 is laminated beneath the channel region 1a′. A side wall formation trench 16 is formed beside the channel region 1a′ of the TFT 30, and in the side wall formation trench a conductive layer having a light shield property is concurrently formed with the first light shield layer 13 thereby a light shield side wall 131 is formed. By three-dimensionally blocking light's entry towards the channel region 1a′, obliquely or laterally incident light is prevented from entering the channel region of a pixel switching TFT, and the TFT 30 is free from erratic operations and reliability degradation.
