摘要： A display device includes a display panel including sub-pixels arranged in a first direction and a second direction perpendicular to the first direction, and including light emitting surfaces in a third direction perpendicular to the first direction and the second direction, and lenses that overlap the sub-pixels in the third direction and to have a long side having an angle greater than 0 degree with respect to the second direction. A first lens includes a first curved surface and a first side surface connected to one edge of the first curved surface. A second lens includes a second curved surface and a second side surface connected to one edge of the second curved surface. The first lens and the second lens share a common lower surface. A flat surface connects the first side surface and the second side surface and extends parallel to the common lower surface.

摘要： A display device includes a display unit including a plurality of pixels to display a display image, a luminance detector to detect luminance of an image on the display unit, and a display driver. The display divider is to divide the display unit into image areas symmetrical to each other and to adjust a luminance of an image area having a relatively lower luminance value among the image areas symmetrical to each other based on a luminance detection result.
