ABSTRACT:
A display device which operates appropriately independently of the manufacture variations of each element formed over a substrate is provided without increasing the number of components. The display device includes an external correction circuit and a panel, and the external correction circuit and the panel are connected to each other through a flexible printed wiring connecting portion. The panel includes a signal line driver circuit, a scan line driver circuit, a pixel portion, a monitoring element portion, a D/A converter and a constant current source. When mounting the D/A converter on a substrate, the number of external circuit components can be reduced without increasing flexible printed wiring terminals by supplying a digital signal inputted to the D/A converter from a video signal line, and controlling the sampling timing of the digital signal with a signal used in the panel.
