Abstract: A display device includes a plurality of pixels, a plurality of scanning signal lines, a plurality of data signal lines, a source driver configured to supply a data signal to the plurality of pixels via a corresponding data signal line of the plurality of data signal lines, and a spare wiring line configured to connect to a disconnected data signal line. For each data signal output to a data signal line with disconnection corrected by the spare wiring line, the source driver sets an output delay amount according to a disconnection position and a line position of a pixel to be supplied with the data signal.

Abstract: A display device according to aspect of the disclosure includes: a source driver; and a timing controller. The source driver and the timing controller perform data communication through serial transmission. The display device further includes a storage unit configured to store information about each of a plurality of standards that are different from each other, the standard defining a protocol for specific serial transmission. The timing controller selects one standard from among the plurality of standards, performs first determination that is determination on the selected standard to determine whether to receive a lock signal from the source driver within a predetermined period after training pattern data compatible with the selected standard is output to the source driver, and outputs an image signal of the protocol of the selected standard to the source driver when a result of the first determination is positive.
