Abstract
In an electro-optical apparatus, such as a liquid-crystal apparatus, a TFT array substrate is provided with pixel electrodes and TFTs connected thereto. In addition, a peripheral area (including a frame area and a sealing area) is provided with peripheral circuits that drive the pixel electrodes, such as data-line driving circuits and a sampling circuit, and wires that send image signals. On an opposite substrate, an opposite electrode is formed so as to avoid areas opposite the wires. Therefore, with a relatively simple structure, parasitic capacitors generated between the wires on one substrate and the opposite electrode on the other substrate are reduced, and high-quality image display having a reduced ghost is achieved.
