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： An object is to provide an OCB-mode liquid crystal display device causing no flicker even with varying environment temperature, and flicker prevention is offered by dividing a transition voltage to that of a first pulse and that of a latter pulse, and varying a ratio of pulse width of a transition voltage, i.e., between the first pulse and the latter pulse, together with any detected environment temperature.

摘要： A liquid crystal layer is formed of a liquid crystal composition including at least one of a compound A which includes a compound of two 6-membered rings in a main skeleton, one of the 6-membered rings being a benzene ring and the other of the 6-membered rings being a cyclohexane ring, and which is expressed by a general formula (1), and a compound B in which both of the two 6-membered rings are cyclohexane rings, and which is expressed by a general formula (2), (each of R and R′ represents an alkyl group or an alkenyl group with a carbon atom number of 2 to 5, and a case in which R and R′ are identical is included).
