Abstract:
In a display device including a display panel, a plurality of scanning line drive circuits formed on the display panel, each driving scanning lines individually, and a display control circuit, the scanning line drive circuit outputs a state signal, and the display control circuit determines whether a state is normal based on the state signal, performs control, in a normal state, for making the plurality of scanning line drive circuits operate in turn, and performs control, in an abnormal state, for stopping an operation of an abnormal scanning line drive circuit and for making a normal scanning line drive circuit operate in turn. A last-stage output signal of the scanning line drive circuit is used as the state signal. With this, a display device capable of lengthening time until an abnormality occurs and keeping display quality even when the abnormality occurs is provided.
