摘要： An organic light emitting diode display includes a lower substrate, a sub-pixel structure, an upper substrate, a sealant, and a first power supply wire. The lower substrate has a display area, a peripheral area, and a pad area. The sub-pixel structure is disposed in the display area on the lower substrate. The upper substrate is disposed on the sub-pixel structure. The sealant is disposed in the peripheral area between the lower substrate and the upper substrate. The first power supply wire is disposed between the lower substrate and the sealant, and overlaps the lower substrate and the sealant. The first power supply wire includes a first protrusion protruding in a first direction that is a direction from the pad area to the display area in the first peripheral area.

摘要： 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.
