摘要： A liquid crystal display device includes substrates which are opposed to each other, a liquid crystal layer which includes an OCB mode liquid crystal and is held between the substrates, a display section which is composed of display pixels that are arrayed in a matrix, and a driving unit which cyclically charges a reverse transition prevention signal and a video signal in each of the display pixels. The driving unit includes circuits for varying a liquid crystal voltage which is retained in the display pixel after the charging of the reverse transition prevention signal, and a liquid crystal voltage which is retained in the display pixel after the charging of the video signal, thereby making a variation amount of the liquid crystal voltage after the charging of the reverse transition prevention signal greater than a variation amount of the liquid crystal voltage after the charging of the video signal.

摘要： A liquid crystal display device includes display pixels which are arrayed in a matrix, a driver circuit which drives the display pixels in units of a predetermined number of rows, and a controller which controls the driver circuit so as to alternately execute non-video signal write in which a non-video signal is written by driving the display pixels on a row-by-row basis, and video signal write in which a video signal is written by driving the display pixels on a row-by-row basis. Each of the display pixels includes a first capacitance which is formed by a voltage applied between electrode substrates, and a second capacitance which is coupled to the first capacitance. The controller includes a control circuit which controls the driver circuit so as to charge a predetermined capacitance on the second capacitance in a superimposing manner during a time period in which the non-video signal write is executed.

摘要： A liquid crystal display includes pixels, driver circuits, and a control circuit. The control circuit sets, in a one-frame period, a first period and a second period shorter than the one-fame period and partly overlapping the first period. The control circuit controls the driver circuits, causing them to write non-video signals for the pixels in the first period, to write video signals for the driver circuits in the second period, and to write the non-video signals and the video signals alternately in units of one or more horizontal periods in a part of the first period, which overlaps the second period, and to output the non-video signals and the video signals alternately in units of one or more horizontal periods in a part of the first period, which does not overlap the second period, and to write the non-video signals in a period for writing non-video signals.

摘要： In one embodiment, a liquid crystal display device includes a first substrate having a first pixel electrode and a first pillar-shaped spacer arranged in an active area, and a second pixel electrode and a second pillar-shaped spacer arranged in a shield area surrounding the active area. A shield layer is formed in the shape of a belt crossing above the first pillar-shaped spacer in the active area and extending to the shield area including a portion above the second pillar-shaped spacer. The height of a first seat layer formed above the first pillar-shaped spacer and including the shield layer, a first color filter layer and an overcoat layer is substantially the same as that of a second seat layer formed above the second pillar-shaped spacer and including the shield layer, a second color filter layer and the overcoat layer.
