发明名称 Vertical alignment liquid crystal display device in which a pixel electrode has slits which divide the pixel electrode into electrode portions
摘要 A liquid crystal display device has an opposing substrate on which an opposing electrode is formed, a TFT substrate on which pixel electrodes arranged in matrix, thin film transistors connected to the pixel electrodes respectively, and gate lines and data lines for the thin film transistors are formed, vertical alignment films formed on the opposing inner surfaces of these substrates, and a liquid crystal layer disposed between the vertical alignment films and having negative dielectric anisotropy. Each pixel electrode has a slit formed for separating each pixel into a plurality of sub-pixels by partially eliminating the pixel electrode with a connecting portion left at which adjoining electrode portions of each pixel electrode is connected with each other. The width W1 of the pixel electrode that runs in a direction in which the slit is formed and width W2 of the connecting portion have a ratio W2/W1 of 0.13 or lower.
