摘要:
A large screen liquid crystal display device using a transverse electric field system which is capable of dramatically improving an aperture ratio, a transmittance ratio, brightness, and contrast with low cost and high production yield. For example, the width of the common electrodes (72) that shield the electric fields of the video signal lines (51) can be decreased dramatically and the aperture ratio can be improved dramatically. Especially, the bumps (73) covering the video signal lines (51) can be used along with the spacers, and with the use of halftone exposure method, the bumps covering the video signal lines and the spacers can be constructed at the same time, which dramatically shortens the time required for the production process.
摘要:
A display suitable for displaying moving images that has excellent viewing angle properties, an excellent reliability, and a high speed of response, and has a high contrast is realized at low cost. Vertically aligned mode liquid crystal display comprises a scan wiring (17), a video signal wiring (11), a pixel electrode (8), an alignment directional control electrode (15), and a thin film transistor element (16) formed in a position where a scan wiring and a video signal wiring intersect with each other, and a common electrode formed in opposing substrate side, wherein an electric field distribution formed with three electrodes comprising said alignment directional control electrode, said pixel electrode, and a common electrode formed on an countering substrate side may control tilt directions of vertically aligned anisotropic liquid crystal molecules having a negative dielectric constant.
摘要:
A process of manufacturing a liquid crystal display device of transverse electric-field type, wherein a halftone photomask (60) which is used to form a photoresist pattern has a fully light-shielding area (62) preventing UV irradiation of a portion of an active matrix substrate in which a thin-film transistor element (58) is to be formed, so that the photoresist- pattern includes a positive resist portion (6) which has a first thickness and which covers the above-indicated portion of the substrate. The halftone mask (60) further has a fully light-transmitting area (65) which permits fully UV transmission therethrough to provide the photoresist pattern with a resist-free area (8) which covers to a portion of the substrate in which a contact hole (59) serving as a third connection portion connecting an external scanning-line driver circuit and a scanning-line terminal portion (19) through a junction electrode (21) is to be formed. The photoresist pattern also has a positive resist portion (7) which covers the other portion of the substrate and which has a second thickness smaller than the first thickness. Also disclosed in a scan-exposing device (100, 110, 120, 130) used in the process.
