Abstract: A display device includes: a pixel unit including a target pixel and peripheral pixels in a unit area set based on the target pixel; a converter configured to adjust a voltage level of a data voltage of the target pixel, based on light emission statuses of the peripheral pixels, and to determine a voltage level of a black voltage of at least one peripheral pixel which does not emit light among the peripheral pixels, based on the light emission statuses of the peripheral pixels; and a data driver configured to apply the data voltage to the target pixel, and to apply the black voltage to the at least one peripheral pixel which does not emit light.

Abstract: A display device includes a display panel and a signal transmission film including a first extension portion, a second extension portion, and a first dummy pattern. The signal transmission film is connected to one side of the display panel. The first extension portion extends in a first direction, and a first contact hole is formed at a first side of the first extension portion. The second extension portion extends from the first side of the first extension portion in a second direction which is different from the first direction. The first dummy pattern is disposed adjacent to the first contact hole at the first side.
