A display device includes: a source driver; a plurality of gate drivers which share a plurality of scan signal lines to which they are connected; a gate output judging section for judging whether or not each of the plurality of gate drivers has a failure, on the basis of timing at which a gate signal Gout is outputted from a corresponding one of the plurality of gate drivers; and a control section for, in a case where the gate output judging section judges that the gate driver has a failure, switching over to the gate driver. This makes it possible to extend a lifetime of the display device with not a complicated arrangement but a simple arrangement.
