Claim:
1. A display device in which a peak luminance control (PLC) curve defines a maximum luminance of pixels according to an average pixel level (APL) of an input image the display device comprising: a luminance controller that establishes multiple PLC points by equally dividing a PLC curve and, when the PLC curve is adjusted by a luminance adjustment variable, limits the luminance of the pixels in a first APL section extending from a lowest PLC point to a predetermined PLC point at an adjusted peak luminance for the lowest PLC point of the PLC curve adjusted by the luminance adjustment variable, and limits the luminance of the pixels in a second APL section after the predetermined PLC point at an initial luminance of the PLC curve which is not adjusted by the luminance adjustment variable, wherein, when a luminance of the display device decreases, the luminance controller adjusts the PLC curve such that the first APL section increases and the second APL section decreases.
