摘要： An active matrix type of twisted nematic liquid crystal display is provided with a lower alignment layer rubbed in rubbing directions RD3, RD4 opposite to each other, an upper alignment layer rubbed in rubbing directions RD5, RD6 opposite to each other, a liquid crystal layer arranged between the lower and upper alignment layers and filled with liquid crystal molecules set in a nematic liquid crystal phase, a pixel electrode and an common electrode for inducing a vertical electric field in the liquid crystal layer, and a source line for applying an electric potential to the pixel electrode. In this case, major axes of a group of liquid crystal molecules arranged above the pixel electrode are twisted in a clockwise direction, and major axes of other group of liquid crystal molecules are twisted in a counterclockwise direction. Therefore, even though a lateral electric field is induced between the pixel electrode and the source line, the liquid crystal molecules are not adversely influenced by the lateral electric field.

摘要： Before starting the regular display in a liquid crystal display device of the bend alignment type, it is necessary to transition all the pixel regions in the entire display portion uniformly from splay alignment into bend alignment. However, conventionally, when applying a simple ac voltage, the transition sometimes does not take place, and when it does take place, the transition time is very long, and display defects due to alignment defects tend to occur.
In the method for driving a liquid crystal display device with OCB cells according to the present invention, a step of applying between an electrode (202b) and a pixel electrode (202a) comprising protrusions (222a) and recesses (221a), an ac voltage superimposed with a bias voltage, and a step of applying zero voltage or a low voltage to the substrates are repeated in alternation preceding the begin of the regular display operation and the regular display operation is carried out after all pixels have transitioned into bend alignment.

摘要： In a liquid crystal display device configured so that ambient light is collected and the collected ambient light is guided to the back of a liquid crystal panel so as to illuminate the liquid crystal panel, a light-collecting unit 17 and a light-guiding unit 18 are provided. The light-collecting unit 17 collects and captures ambient light, and converts the ambient light into a transmitting light which transmits in the light-collecting unit 17. The light-guiding unit 18 connected to the light-collecting unit 17 redirects a light path of the transmitting light from the light-collecting unit 17 so that the transmitting light proceeds to the back of a liquid crystal panel 15. Thus, unlike conventional light-collecting units, a light-collecting unit of the invention is composed of two separated units, one being a light-collecting unit for converting ambient light into a transmitting light and the other being a light-guiding unit for guiding the transmitting light to the liquid crystal panel. This configuration attains an increase in an occupied area of the light-collecting unit and thereby achieves an increased brightness of the liquid crystal display device.
