ABSTRACT:
An active-matrix addressing LCD device using lateral electric field realizes a higher transmittance and a higher fabrication yield and improves the aperture ratio without raising the fabrication cost. A first one of the common electrode lines, a first one of the pixel potential layers, and an intervening dielectric layer constitute a first storage capacitor for each of the pixels and at the same time, a second one of the common electrode lines, a second one of the pixel potential layers, and the intervening dielectric layer constitute a second storage capacitor for the same pixel. The first and second pixel potential layers are electrically connected to each other by way of a corresponding transparent pixel electrode. Therefore, the rotation of the liquid crystal molecules caused by applied electric field makes full contribution to the panel transmittance, preventing the obtainable total panel transmittance from lowering. This means that a higher transmittance is obtainable. An interconnection electrode may be additionally provided for the same purpose.
