Abstract: A display device includes a lighting device, a display panel, a memory, and a correction circuit. The lighting device includes a light exit area defined into light exit sections corresponding to light sources. The display panel includes a display area disposed opposite the light exit area and including pixels. The memory stores data of pixel matrix linked to the display sections. The memory stores position data of the pixels that are not disposed opposite the corresponding light exit sections and deviation data when a position error is caused between the light exit area and the display area. The correction circuit is configured to determine whether the memory stores the position data of the pixels and link new pixel matrix units to the corresponding display sections based on the deviation data if a determination result is affirmative.
