Abstract
A liquid crystal displaying apparatus which is high in displaying quantity is provided, wherein the displaying quantity reduction such as flickering, image sticking, ununiformly displaying and so on which is caused due to changes for each exposing region of the &Dgr;Vgd. In the liquid crystal displaying apparatus of the present invention, a plurality of scanning wirings and a plurality of signal wirings, TFTs and pixel electrodes are formed. Storage capacitance for retaining the electric charge is connected with the pixel electrode, another electrode opposite to an electrode for forming the storage capacitance and the drain electrode of the TFT are formed at the same time, an array substrate where another electrode is superposed on the scanning wiring and the signal wiring through the transparent insulating film, and a liquid crystal displaying provided with an counter substrate having a common electrode to be arranged opposite to the pixel electrode. The change in the &Dgr;Vgd due to changes in the Cgd to be caused for each exposing area is compensated by changing the Cs value for each exposing region.
