Abstract

An image display device includes thin film transistors and pixel electrodes arranged in matrix form on a substrate. A semiconductor layer forming a channel region of the thin film transistor also serves as the pixel electrode, thereby making the structure of the device simple and facilitating fabrication thereof.
