Display device, and method for correcting display state of display device

Abstract

A display device includes: a display device main body including a display panel and a screen calibration function unit that calibrates a display state of the display panel; and a cover that covers the display panel, the cover including an optical sensor in a surface facing the display panel. The optical sensor measures a screen state of the display panel in a state where the display panel is covered with the cover, and sends a measured value of the optical sensor to the display device main body. The screen calibration function unit calibrates the display state of the display panel by using the measured value.
