Abstract
An active matrix liquid crystal display device includes a thin film transistor (TFT) array substrate and a counter electrode substrate with a liquid crystal layer held therebetween. On a surface of the counter electrode substrate adjacent to the liquid crystal layer, a plurality of counter electrodes are formed perpendicular to gate lines on the TFT array substrate. Each of the counter electrodes faces at least one column of pixel electrodes connected to drain electrodes of the TFTs.
