Abstract: A display device has: a display panel; a source driver group including 2j source drivers that are arranged in the lengthwise direction of gate lines; and a display controller that is connected to the 2j source drivers via j data supply lines provided in common between adjacent pairs of source drivers. The display controller outputs j pixel data piece groups, into which m/2 pixel data pieces were divided, to the data supply lines. The (2k)th source driver receives m/(4j) pixel data pieces via a data supply line, and receives three pixel data pieces from the (2k+1)th source driver. The (2k)th source driver generates m/(2j) of gradation voltage signals on the basis of the pixel data pieces.
