Abstract: A display device includes a display panel including a first region and a second region, and a sensing module on a rear side of the display panel. The first region includes a first pixel area to display an image. The second region includes a second pixel area to display the image and a transmission area to transmit light output by the sensing module. The second region overlaps the sensing module. The second pixel area overlaps a first layer that blocks light output by the sensing module. The transmission area does not overlap the first layer.
