IPC: G09F9/30
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which is improved in mass- productivity and has a wide viewing angle, high picture quality, and high reliability. SOLUTION: In an IPS system liquid crystal display device having a wide viewing angle, dark spot-like unevenness (core stain) occurs when its is continuously energized for display. Moreover, since the IPS system uses a liquid crystal with low specific resistance, impurities in the liquid crystal flow during display and cause dark indefinite forms of unevenness, or collect at an end part of a display pattern to cause an afterimage (burning).  In order to prevent these, the liquid crystal display device, wherein a liquid crystal layer is held between a pair of substrates and plural pieces of pixels are formed in a matrix form on one of the substrates, is characterized in that a 1st electrode group and wiring group for displaying a video are formed on the substrate on which the plural pixels are formed; a protective film is formed between the liquid crystal layer and the 1st electrode group and wiring group; and between the protective film and the other one of the substrates, a 2nd electrode or wiring consisting of either of a cathode and an anode or both or them is at least singly formed in the plural pixels. Thus the core stain and the dark spot-like unevenness are dissolved and the afterimage (burning) is reduced.
