Patent ID: 8436795

Claim:
An electro-optical device comprising: a thin-film transistor array substrate; a pixel area on the thin-film transistor array substrate, the pixel area including a pixel portion; a scanning line and a data line which cross each other in the pixel area; a scanning-line driving circuit disposed in a peripheral region around the pixel area, the scanning-line driving circuit supplying a scanning signal to the pixel portion through the scanning line; a data-line driving circuit disposed in the peripheral region, the data-line driving circuit supplying a sampling signal; a sampling circuit that receives the sampling signal from the data-line driving circuit, samples an image signal in accordance with the sampling signal, and supplies the sampled image signal to the data line, the sampling circuit being disposed in a region between the data-line driving circuit and the pixel area; a sealing portion sealing a liquid crystal inlet disposed between the sampling circuit and the pixel area; and a plurality of light-shielding films formed on the thin-film transistor array substrate, the plurality of light-shielding films completely overlapping the scanning-line driving circuit and the data-line driving circuit in plan view, and avoiding overlapping other circuits of the peripheral circuit portion disposed in the peripheral region, the plurality of light-shielding films being disposed between the thin-film transistor array substrate and each of the scanning-line driving circuit and the data-line driving circuit, wherein the plurality of light-shielding films avoids overlapping the region between the data-line driving circuit and the pixel area such that the plurality of light-shielding films completely avoids overlapping the sampling circuit and the sealing portion.
