1. A display device, comprising:
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 comprising pixels connected to scan lines and data lines, and each of the pixels including a first transistor configured to control an amount of 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,
wherein each of the pixels further comprises:
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 the luminance control signal having an enabled state,
wherein 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.
