Abstract: A display device includes overlapping two display panels. The display panel on the upper side includes a first display region and a region that transmits visible light. The display panel on the lower side includes a second display region and a region that blocks visible light. The second display region overlaps with the region that transmits visible light. The region that blocks visible light overlaps with the first display region. The display panel on the lower side includes a third display region between the second display region and the region that blocks visible light. The gate signal and the source signal supplied to a first pixel in the third display region are the same as the gate signal and the source signal supplied to a second pixel in the second display region. The second pixel is closer to the first pixel than any other pixels included in the second display region.

Abstract: A high-resolution display device is provided. The display device includes a plurality of light-emitting units emitting light of different colors. The light-emitting unit has a microcavity structure and intensifies light with a specific wavelength. In the light-emitting units emitting light of different colors, reflective layers with different thicknesses are formed, an insulating layer is formed to cover the reflective layers, and then a top surface of the insulating layer is subjected to planarization treatment, whereby an insulating layer with different thicknesses is formed. After that, light-emitting elements emitting white light are formed over the planarized top surface of the insulating layer to overlap with the respective reflective layers, whereby the light-emitting units that intensify different colors due to different optical path lengths are separately formed.
