Abstract: A display device includes: a power supply configured to supply a voltage of first driving power to a first power line, and supply a voltage of second driving power to a second power line; a display panel including pixels connected to scan lines and data lines, and each including a first transistor configured to control current supplied from the first power line to the second power line via a light emitting element; and a timing controller configured to supply a luminance control signal to the pixels. Each of the pixels includes: a control transistor connected in parallel to some sub-transistors of the corresponding first transistor, and configured to be turned on in response to receipt of a luminance control signal having an enabled state. The power supply changes the voltage of the second driving power when the luminance control signal having the enabled state is supplied to the pixels.
