    摘要： A liquid crystal display and a method of operating such liquid crystal display in which display operation is performed by changing a director of said liquid crystal molecules mainly in a plane parallel to first and second substrate forming a liquid crystal display panel. Liquid crystal molecules in the liquid crystal display panel have a negative anisotropy of permittivity. The liquid crystal display comprises: a first common electrode disposed on the side of said first substrate; an insulating layer formed on the first common electrode; at least one pixel electrodes each of which is formed on the insulating layer and has a plurality of opening portions; a second common electrode disposed on the side of the second substrate. The first common electrode comprises at least a particular portion formed in a particular area which extends from a non-opening portion to an opening portion of the pixel electrode and in which the first common electrode overlaps the non-opening portion in a cross section perpendicular to the substrates.

    摘要： In an orientation division type liquid crystal display device for widen a viewing angle of a display pixel of an active matrix type liquid crystal color display device having a COT structure, pixel color layers (6B, 6R, 6G) as color filters and pixel electrodes 3 are formed on a substrate on the side of the pixel electrodes and slopes 13 are provided along four side peripheries of each pixel electrode. Liquid crystal molecules 8 between each pixel electrode of the pixel electrode substrate and a common electrode of an opposing substrate are controlled in orientation direction along the slopes to divide it to a plurality of directions to thereby widen a viewing angle of a pixel display. The slope is formed on a step portion 12 formed by a BM layer formed on at least one of a gate electrode, a drain electrode and a source electrode formed in a periphery of the pixel electrode or at least one of a gate wiring and a drain wiring formed in the periphery or a step portion formed by partially overlapping peripheral portions of the adjacent pixel color layers.

    摘要： A liquid crystal display panel comprises a TFT substrate unit having a thin film transistor (TFT), a control electrode connected to the TFT, a flattening film covering the control electrode, and a pixel electrode having a cross slit and formed on the flattening film and insulated from the control electrode. An opposite substrate unit has an opposite electrode facing the pixel electrode at a predetermined position. A liquid crystal layer disposed between the TFT substrate unit and the opposite substrate includes liquid crystal molecules having negative dielectric aeolotropy. When voltage is supplied between the control electrode and the opposite electrode, an electric field is generated between them. The electric field divides the liquid crystal layer into four domains in each pixel according to the cross slit formed in the pixel electrode.
