Abstract: A display device includes a plurality of pixels arranged in a display area of a display panel, and a display driving circuit supplying data voltages and pixel driving control signals to the plurality of pixels to control an image display operation for each of the plurality of pixels. The display driving circuit further supplies an active control voltage that varies proportional to or inversely proportional to a change in temperature of the display panel to at least one thin film transistor included in the plurality of pixels.
