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 substrate, a pixel area, and a plurality of data lines. The substrate includes display and non-display areas. The pixel area is in the display area and includes a first pixel column and a second pixel column. The pixels in the first and second columns emit light of different colors. The data lines are respectively coupled to the first pixel column and the second pixel column. In the non-display area, a data line is coupled to one of the first or second pixel columns corresponding to a color on which influence of a resistance is greater than on another color. The data lines has a line or contact structure with a resistance less than a resistance of a line or contact structure of a remaining data line coupled to a remaining pixel column.
