A video display apparatus includes a brightness modulating circuit that reduces the image brightness of the peripheral area of a display panel as compared to that of the central area of the display panel, and a control circuit that controls the operation of the brightness modulating circuit on the basis of the power consumption of the display panel in which the control circuit controls the brightness modulating circuit to be active when the power consumption of the display panel exceeds a predetermined threshold, and stops the operation of the brightness modulating circuit when it is smaller than the predetermined threshold.
