Abstract:
A method of manufacturing a liquid crystal display device including a TFT substrate with display and peripheral regions. The display region has pixels each having a pixel electrode and a TFT. A counter substrate opposes the TFT substrate and has a color filter formed at a position corresponding to a position at which the pixel electrode is formed above the TFT substrate. The method includes coating, outside of the display region of the TFT substrate, a second alignment film in the shape of a frame, and coating, in the display region, a first alignment film that dries more slowly than the second alignment film. The first and second alignment films are in contact, and the second alignment film is thicker than the first alignment film.
