    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 first display area including a plurality of first pixel areas and a second display area including a plurality of second pixel areas and a plurality of light transmitting areas. Each of the plurality of first pixel areas includes at least one first pixel to display an image. Each of the plurality of second pixel areas includes at least one second pixel to display the image. The light transmitting area does not include a pixel capable of displaying the image and has higher light transmittance than the second pixel area. In the second display area, at least one of the plurality of light transmitting areas is between two second pixel areas adjacent in a first direction, and at least one of the plurality of light transmitting areas is between two second pixel areas adjacent in a second direction different from the first direction.

    Abstract: A display device includes signal lines and pixels connected thereto. A first pixel includes a first transistor including a first gate electrode, a first channel region overlapping the first gate electrode, a first source region, and a second drain region facing the first source region, with the first channel region interposed between the first source region and the second drain region. A third transistor includes a third gate electrode, a third channel region overlapping the third gate electrode, a third drain region connected to the first gate electrode, and a third source region facing the third drain region with the third channel region interposed between the third source region and the third drain region. A shielding part overlaps a boundary between the third source region and the third channel region and does not overlap a boundary between the third drain region and the third channel region.
