    Abstract: According to an aspect, a display device includes an image display panel; a planar light source including a light guide plate, a first sidelight light source, and a second sidelight light source; and a control unit. The control unit sets first luminance determination blocks in a first display surface of the image display panel and identifies a first luminance determination block to be a target of luminance correction by referring to luminance information on the light sources. The control unit sets second luminance determination blocks in a second display surface of the image display panel and identifies a second luminance determination block to be a target of luminance correction by referring to the luminance information on the light sources. The control unit controls light source lighting amounts of the respective light sources to satisfy luminance of the identified first luminance determination block and the identified second luminance determination block.

    Abstract: According to an aspect, a display device includes a display panel comprising a plurality of pixels, a light guide plate, a light source configured to emit light from a lateral side of the light guide plate, a dimming panel, and a controller. The dimming panel comprises a plurality of dimming areas arranged in an emission direction of the light from the light source. The dimming areas are capable of individually changing transmittance of the light according to intensities of light required to display an image using the display panel. When adjacent two of the dimming areas differ in light transmittance from each other, the controller increases output gradation values of target pixels, the target pixels being located in a predetermined area extending from a boundary between the two dimming areas in one of the two dimming areas that has lower light transmittance.
