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 pixel includes a pixel circuit and an organic light emitting diode. The pixel circuit has first, second, third, and fourth transistors. The first transistor controls an amount of current flowing from a first driving power supply coupled to a first node to a second driving power supply through the organic light emitting diode. The turns on when a scan signal is supplied to a first scan line. The third transistor turns on when a scan signal is supplied to a second scan line. The fourth transistor turns on when a scan signal is supplied to a third scan line. The first transistor is a p-type Low Temperature Poly-Silicon thin film transistor and the third transistor and the fourth transistor are n-type oxide semiconductor thin film transistors.
