摘要： In a liquid crystal display device, a liquid crystal with the negative dielectric anisotropy filled between a TFT substrate and a CF substrate, and the TFT substrate has a pixel electrode and an auxiliary electrode formed around the pixel electrode. The pixel electrode is a transparent electrode comprising an ITO layer, and has a slit formed from the center portion of each pixel toward the periphery portion thereof, for segmenting a pixel region into a plurality of sub-pixel regions. A recess portion for forming the center of the alignment of liquid crystal molecules is formed on the center of each segmented sub-pixel region. The liquid crystal of the sub-pixel region is aligned toward the center of the sub-pixel region by a horizontal electric filed applied between the pixel electrode and the auxiliary electrode, and, an oblique electric field generated at the edge of the slit.

摘要： A liquid crystal with a negative dielectric anisotropy is filled between a pair of substrates, on one of which an opposing electrode is provided while pixel electrodes and an auxiliary electrode formed around the pixel electrode are provided. The pixel electrode is a transparent electrode comprising an ITO layer, and is formed with a slit for segmenting a pixel region into a plurality of sub-pixel regions. The slit is formed from the center portion of each pixel toward and the peripheral portion thereof. The auxiliary electrode is also formed under the pixel electrode at a position which corresponds to the slit. Liquid crystal molecules of each sub-pixel region are so aligned as to tilt toward the center of the sub-pixel region when a voltage is applied between the pixel electrode and the opposing electrode.
