ABSTRACT:
A matrix-type image display device of the present invention is arranged such that image data are selectively applied to pixels arranged in a matrix form through scanning signal lines and data signal lines, and the image data are stored therein, wherein a high potential of a sampling pulse 0V/5V to be output from a logic circuit is shifted to 10 V, and a low potential thereof is shifted to -8 V respectively by first and second level shifters. As a result, a difference between an input signal level from an external circuit such as a control circuit, an image signal processing circuit, etc., and an actual driving signal level of each pixel can be absorbed. Therefore, an additional structure such as an interface circuit, etc., is not needed between the external circuit and the scanning signal line driving circuit, thereby enabling a low cost and a low power consumption.
