Abstract
A display device includes: a display unit including pixels; a shift register connected to scan signal lines and outputting a pulse signal sequentially, the shift register being divided into shift register segments; a driver generating a clock signal to be supplied to each segment, and a video signal to be input to each pixel; and a controller controlling the driver for generating the clock signal and the video signal, the controller monitoring output of each segment and detecting a malfunction of any of the segments. A shift register unit of a first stage of each segment outputs the pulse signal at a prescribed timing after receiving a start signal. The unit of a stage differing from the first stage outputs the pulse signal at a prescribed timing after receiving a carry signal based on the pulse signal from the unit of a preceding stage.
