Abstract: Embodiments of the present disclosure relate to a display device including a substrate, an optical device located under the substrate in a display area, and a subpixel layer located over the substrate in the display area, wherein the subpixel layer includes at least one of first transistor with a first characteristic are located at a first area overlapping with the optical device, and at least one of second transistor with a second characteristic are located at a second area not overlapping with the optical device.

Abstract: The present disclosure relates to display panels and display devices that are capable of simplifying a manufacturing process and more specifically to: a display area including a first optical area including a central area and a bezel area located outside of the central area and a normal area located outside of the first optical area. A plurality of light emitting elements disposed in the central area and a plurality of light emitting elements and a plurality of transistors including a plurality of source-drain electrode patterns are disposed in the bezel area. There is a connection pattern contacting a first source-drain electrode pattern in the bezel area and extending to a portion of the central area. In one embodiment, one of the plurality of source-drain electrode patterns and the at least one connection pattern are disposed on a same layer and include different materials.

Abstract: A display device is disclosed that includes a display panel comprising a display area and a non-display area, wherein the display area comprises a first area and a second area surrounded by the first area, and the second area comprises one or more of light emitting areas in which one or more of pixels are disposed and one or more of transmissive areas; a pixel defining layer positioned between the plurality of pixels; and a metal layer positioned in the plurality of light emitting areas, wherein an end of the metal layer is aligned with a boundary between the light emitting area and the transmissive area, and an end of the pixel defining layer overlaps the light emitting area without extending to the boundary.

Abstract: A display panel may include a first area in which a plurality of pixels are disposed, and a second area having at least two pixel groups. Each of the at least two pixel groups may include at least one pixel, a light transmittance portion disposed between the at least two pixel groups to transmit light, and a hole formed to correspond to a boundary of the light transmittance portion. A cathode related to the at least one pixel may be disposed in at least a part of the hole.
