Abstract:
1. An active matrix liquid crystal display device comprising: a pixel transistor; a wiring layer that is connected to the pixel transistor; a first insulating layer that is provided on the pixel transistor and the wiring layer; a lower electrode layer that is provided on the first insulating layer and used as one of a common electrode layer and a pixel electrode layer; a second insulating layer that is provided on the lower electrode layer; and an upper electrode layer that is provided on the second insulating layer and used as the other of the common electrode layer and the pixel electrode layer, wherein where a display pixel has a substantially square shape and is composed of a plurality of sub pixels, a pitch at which the display pixels are arranged vertically and a pitch at which the display pixel are arranged horizontally are respectively P per 25.381 mm, a channel width of the pixel transistor is W, the on resistance per unit channel width of the pixel transistor is ρ liquid crystal molecules are driven by applying voltage between the upper electrode layer and the lower electrode layer.
