Patent ID: 6989844

Claim:
An image display, comprising: an image display unit constituted by a plurality of pixels; a plurality of signal lines arranged within said image display unit in order to input a display signal to said pixel; a gradation voltage line group to which gradation voltage that is an analog value is applied; switching means provided for each of said signal lines in order to selectively connect any of gradation voltage lines to which predetermined gradation voltage is applied from said gradation voltage line group to said signal line; a switch driving line for driving said switching means; decoding means for driving said switch driving line based on display signal data inputted in digital form; and switching means selecting means for selectively inputting a driving signal inputted to said switch driving line to a plurality of said switching means, wherein said pixel, said signal line, said switching means, said decoding means, and said switching means selecting means are formed on the same substrate, and wherein said pixel, said switching means, said decoding means and said switching means selecting means are constituted by only a single channel transistor of either n-channel or p-channel.
