Abstract

See full text

A liquid crystal display device of an OCB mode includes a liquid crystal layer held between an array substrate and a counter-substrate, and a display section composed of display pixels arrayed in a matrix. The array substrate includes pixel electrodes which are disposed in association with the display pixels. The counter-substrate includes a counter-electrode opposed to the pixel electrodes. The substrates include a pair of alignment films which are disposed on the pixel electrodes and the counter-electrode, respectively, and are subjected to rubbing treatment to control an alignment state of liquid crystal molecules included in the layer. A transition-nucleus formation section, which generates an electric field for transitioning the alignment state of the liquid crystal molecules included in the layer from a non-display state to a display state, is provided on a terminal-end side of a rubbing direction of each of the alignment films in each of the display pixels.
