Abstract:
1. A display device comprising: buffers each of which is provided in association with each wiring constituting a group of wirings serving as signal lines of a display panel in order to drive the corresponding wiring; a preliminary buffer provided to drive a preliminary wiring, an input terminal of the preliminary buffer being configured to be short-circuited to an output of the buffers which drives a defective wiring in a state in which the preliminary buffer is used; and a charge distributor for performing charge distribution between the wirings and the preliminary wiring, wherein: the charge distributor short-circuits outputs of the respective buffers to each other and also short-circuits the outputs of the buffers and an output of the preliminary buffer to each other in the charge distributing operation in the state in which the preliminary buffer is used, and the charge distributor further short-circuits only the output of the buffers to each other in the charge distributing operation in a state in which the preliminary buffer is not used.
