In order to display an image or display information on such a display device, there must be an associated driving circuit for driving the image, as well as a control circuit for controlling the driving circuit. This is because, in general, the image display is possible only when the image signal is applied or the pixel is controlled to the pixel which is the minimum unit of the image in the display device. In addition, a plurality of signal lines and at least one TFT (Thin Film Transistor) are disposed to apply an image signal to a pixel or to control the pixel for each pixel unit.
