Abstract

The object of the present invention is to provide a vertical alignment type liquid crystal display device, which can eliminate charging phenomenon, reduce unique display unevenness, and is suitable for multi-channel driving. A liquid crystal display device uses a substrate with front electrodes on the surface and a substrate with back electrodes to sandwich the liquid crystal layer. The orientation of the liquid crystal layer is perpendicular to the electrode surface when no voltage is applied, and the orientation is oriented when voltage is applied by multi-channel driving. changes to become parallel to the substrate within the pixel. The resistivity of the liquid crystal layer is in the range of 1×1010 Ωcm to 2×1011 Ωcm, and a pixel is divided into multiple sub-pixels by using the pixel division unit arranged on the front surface electrode, that is, a slit, so that the adjacent sub-pixels sandwiching the slit The direction of the alignment change of the liquid crystal layer when the voltage is applied is different, and the formation pitch (P1) of the sub-pixels is in the range of 50 μm to 100 μm.

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] A liquid crystal display device has a structure in which a liquid crystal layer is interposed between a transparent substrate disposed on the observer's side and a transparent substrate opposed to the transparent substrate disposed on the opposite side of the observer. The liquid crystal layer is composed of, for example, a nematic liquid crystal (hereinafter also referred to as a nematic liquid crystal). A patterned transparent electrode made of, for example, ITO (Indium Tin Oxide: Indium Tin Oxide) or the like is provided on the inner surface of each substrate. An alignment film is provided between the electrodes on each substrate and the liquid crystal layer as a liquid crystal alignment layer for realizing uniform initial alignment of liquid crystals. Then, according to the electric field applied between the electrodes, the orientation of the liquid cr...
