Abstract: A display device includes: a substrate having a first display area and a second display area. A first pixel circuit portion is disposed on the substrate. A first emitting diode includes a first pixel electrode connected to the first pixel circuit portion. A second pixel circuit portion is disposed on a second display area of the substrate. An extension wire is connected to the second pixel circuit portion. A second emitting diode includes a second pixel electrode connected to the extension wire, and a driving circuit portion is connected to the first pixel circuit portion and the second pixel circuit portion, and overlaps the second emitting diode. The extension wire is disposed in a different layer from the second pixel electrode.

Abstract: A display device includes a substrate, a display panel including a first display region having first pixels, a second display region having second pixels, and a third display region located between the first and second display regions and having third pixels, and a component disposed between the substrate and the display panel and which overlaps the second display region in a plan view. The first and third pixels are disposed at a first density in the first display region and the third display region, respectively, and the second pixels are disposed at a second density smaller than the first density in the second display region, and less than all of the third pixels are controlled to emit light during a predetermined display period.

Abstract: A display device includes a display panel including a main area and a sensor area. Sensor devices overlap the sensor area of the display panel in a thickness direction of the display panel. The display panel includes first subpixels, which are disposed in the sensor area, and second subpixels, which are disposed in the main area. The number of transistors of each of the first subpixels is different from the number of transistors of each of the second subpixels.

Abstract: A display device including a display panel having a display area in which a plurality of pixels are arranged, and a light source unit overlapping the display panel and including at least one light source. The light source unit irradiates infrared light to a predetermined region within the display area when displaying an image on the display area to change the luminance of pixels disposed in the predetermined region.
