Abstract: A display device includes a substrate including a first display area and a second display area. The first display area includes first pixel areas, each including one or more first pixels. The second display area includes second pixel areas including one or more second pixels and a light transmittance area having a higher light transmittance than the second pixel area. The first and second display areas include a common electrode that transmits a constant common voltage. The common electrode in the second display area includes patterned regions that correspond to a first light transmittance area included in the light transmittance area. A thickness of the common electrode in the patterned regions is smaller than a thickness of the common electrode in a region other than the patterned regions or equals zero. The patterned regions and the second pixel areas extend alternately along a first direction in the second display area.

Abstract: A display device includes a display panel including a first region and a second region, and a sensing module on a rear side of the display panel. The first region includes a first pixel area to display an image. The second region includes a second pixel area to display the image and a transmission area to transmit light output by the sensing module. The second region overlaps the sensing module. The second pixel area overlaps a first layer that blocks light output by the sensing module. The transmission area does not overlap the first layer.
