摘要： A liquid crystal display device includes a pair of substrates, a liquid crystal between substrates and alignment layers disposed on the inner surface sides of the substrates. The alignment layer is made from a material including polyamic acid containing a diamine component and polyimide containing a diamine component different from the diamine component of the polyamic acid. The alignment layer is subjected to alignment treatment by irradiation of light. UV light can be irradiated in the oblique direction onto the alignment layer through a mask having openings. A reflecting plate can be arranged between a UV light source and the mask. Also, bank structures having a thickness from 0.1 to 0.15 μm can be provided on the alignment layer of the TFT substrate.

摘要： A liquid crystal display including two substrates, gate bus lines, liquid crystal molecules, and a polymer that determines directions in which the liquid crystal molecules tilt. A plurality of divisional areas are arranged on one of the substrates. The pixels are aligned in a column between drain bus lines. A pixel electrode is formed at each of the divisional areas. A first thin film transistor drives a first divisional area, and a second thin film transistor drives a second divisional area of the same column. The first and second thin film transistors are electrically connected to the same gate bus line. Either the pixel electrodes formed at each of the divisional areas are electrically insulated from each other, or they are connected to each other through a high resistance. A first threshold voltage within the first divisional area is different from a second threshold voltage of the second divisional area.

摘要： Opening portions (opening patterns) having different arrangement pitches and sizes are formed in first metal film patterns, a first semiconductor film, second metal film patterns, a third insulating film, and the like under a reflective electrode, respectively. These opening portions overlap each other complexly to form fine bumps and dips in the surface of the reflective electrode. Further, the opening portions can be formed in the first metal film patterns, the first semiconductor film, and the second metal film patterns simultaneously with the formation of TFTs. Accordingly, an increase in the number of steps can be avoided.
