摘要： A display apparatus includes: a display unit that includes a display area including display elements arranged in a two-dimensional matrix and is configured to display an image in the display area based on a video signal; and a correction signal generation unit configured to generate a correction signal that accelerates a change with time for a display element having a small change with time and performs a slowdown or a stop of the change with time for a display element having a large change with time, based on a value of the video signal and time-varying characteristics of a luminance of each display element. When the display apparatus is not used after a normal image is displayed based on the video signal, a corrected image based on the correction signal is displayed to equalize a degree of the change with time of each display element.
