Abstract
A liquid crystal display apparatus has a plurality of TFTs and pixel electrodes disposed in a matrix form in regions surrounded with scanning lines and signal lines disposed on a glass substrate. The display apparatus also has an auxiliary capacitor electrode formed almost all over a display screen in such a way that the auxiliary capacitor electrode is opposed to the pixel electrodes with interposition of an insulation film therebetween. A slit is formed in the auxiliary capacitor electrode in a region corresponding to a gap between the adjacent pixel electrodes. Each pixel electrode may overlap the scanning lines and/or the signal lines. The width of the slit of the auxiliary capacitor electrode may be larger than the width of the gap between the adjacent pixel electrodes.
