Abstract: A foldable display device is disclosed that includes a flexible display panel, an optical module, and a deterioration compensator. The flexible display panel includes a folding line, a first display area disposed on a first side of the folding line, and a second display area disposed on a second side of the folding line to display a test image. The optical module is disposed in the first display area and is configured to sense a display luminance of the test image. The deterioration compensator is configured to perform a deterioration compensating operation of the display luminance by a luminance compensation value when the display luminance is less than a target luminance, without performing the deterioration compensating operation when the display luminance is greater than the target luminance.
