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.
