ABSTRACT:
The invention provides an electro-optical device that can include a pixel electrode, a thin-film transistor (TFT) including a semiconductor layer connected to the pixel electrode, and a data line and scanning line connected to the TFT. The scanning line can include a narrow part as a gate electrode facing a channel region in the semiconductor layer, and a wide part not facing the channel region.Such construction permits the electro-optical device to display high quality images by preventing light from impinging the TFT.
