摘要： After supply of power, a liquid crystal display device performing transition from a first state to a second state different from the first state before a display operation is provided with a transition nucleus forming portion around a pixel electrode or inside. The transition nucleus forming portion performs transition to the second state prior to other portion during a transition drive period. The transition nucleus forming portion of the pixel electrode has an edge portion formed into a reverse taper shape decreasing in its thickness toward the tip end. Therefore, transition from a splay alignment to a bend alignment is performed with simple element and drive circuit configuration in all pixels.

摘要： 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.

摘要： A liquid crystal display includes an insulating substrate, an alignment layer covering a main surface of the insulating substrate, and electrodes interposed therebetween. The alignment layer defines an alignment direction parallel to the main surface, an upstream side as one end's side of the alignment direction, and a downstream side as another end's side of the alignment direction, and tilts liquid crystal molecules toward the downstream side. Each electrode includes an upstream section that includes a first edge facing the upstream side and a downstream section that includes a second edge facing the downstream side and is provided with a recess recessed relative to the second edge. The first recess forms on the downstream section a third edge extending in the alignment direction and a fourth edge connecting the third edge to the second edge and facing the upstream side.
