Abstract
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 Wof the pixel electrode that runs in a direction in which the slit is formed and width Wof the connecting portion have a ratio W/Wof 0.13 or lower.
