ABSTRACT:
In a TFT active matrix electro-optical device, the pixel-aperture ratio is increased while a pixel electrode and a semiconductor layer are interconnected, and a high resolution image can be displayed, with a relatively simple structure. For that purpose, the electro-optical device includes a TFT array substrate provided with a TFT, a data line, a scanning line, a capacitor line, and a pixel electrode. The pixel electrode and the TFT are electrically connected to each other, and are interconnected by a first barrier layer through contact holes. A second barrier layer is formed broader than the data line, and a portion of the second barrier layer overlaps the pixel electrode, and thus the pixel-aperture region is delimited.
