Abstract
The present invention is to prevent a capture error of display data caused by a delay due to a built-in driving circuit in a display device with a built-in driving circuit. The display device comprises: a display area having a plurality of sub pixels; and a driving circuit formed at the periphery of the display area; wherein the driving circuit includes: a first scanning circuit that performs scanning in a first direction; and a latch circuit which latches display data inputted from external based on a scanning output outputted from the first scanning circuit; wherein the driving circuit includes a timing correction circuit which corrects the timing of level change of the scanning output outputted from the first scanning circuit based on a display data synchronization clock inputted from external; wherein the latch circuit latches display data by means of a corrected scanning output outputted from the timing correction circuit; and wherein a transmission line up to the latch circuit of the display data and a transmission line up to the timing correction circuit of the display data synchronization clock are adjacently arranged.
