A display apparatus is capable of displaying an image at a proper luminance based on an input video signal without being influenced by temperature changes or time-dependent changes. The display apparatus is provided with a monitoring circuit constituted by a monitoring luminescent device, a reference current source of a reference drive current for causing the monitoring luminescent device to emit light at a luminance of K %, a transistor for supplying the reference drive current to the monitoring luminescent device, and a switch for connecting an output end of the reference drive current and a control end of the transistor. An input video signal is corrected to have a level according to the voltage value on the control end of the transistor driving the monitoring luminescent device when the luminance indicated by the video signal is K % of a maximum luminance level.
