Abstract: The present disclosure provides a display panel and a display device that include a display area including a first optical area, a first optical bezel area located outside of the first optical area, and a normal area located outside of the first optical bezel area, and a non-display area, wherein each of the first optical area, the first optical bezel area, and the normal area may include two or more light emitting areas among a plurality of light emitting areas, and the first optical area may be a transmittable area. The plurality of light emitting areas may include a first light emitting area included in the first optical area, a second light emitting area emitting light of the same color as the first light emitting area and included in the first optical bezel area, and a third light emitting area emitting light of the same color as the first light emitting area and included in the normal area. The second light emitting area may have substantially the same area as each of the first and third light emitting areas.

Abstract: Embodiments of the disclosure relate to a display panel and a display device that may provide a line characteristic deviation reduction structure and a transmittance variation range reduction structure. The device includes signal lines and a common electrode on the substrate. The display area of the device includes a first optical area where light is transmitted, and a normal area positioned outside the first optical area. The normal area includes emission areas, and the first optical area includes emission areas and first transmissive areas. The common electrode includes common electrode holes respectively positioned in the first transmissive areas. The signal lines include normal signal lines not passing through the first optical area and disposed only in the normal area, and specific signal lines passing through the first optical area. Each specific signal lines overlap at least one common electrode holes.

Abstract: A display device can include a display panel including a non-display area and a display area. The display area can include a first area, a third area surrounded by the first area, and a second area disposed between the first area and the third area. Here, at least one of the first, second, and third area can include a plurality of light emitting areas and a plurality of transmission areas. The display device can further include an optical electronic device located under, or in a lower portion of, the display panel and overlapping at least a portion of the first area included in the display area. The display panel can include a light shield layer disposed under transistors in the plurality of light emitting areas and not disposed in the plurality of transmission areas.

Abstract: The present disclosure provides a display panel and a display device including a display area and a non-display area. The display area includes light emitting areas and signal lines, an optical area, and a normal area outside the optical area. The normal area includes a non-transmission area including light emitting areas, and the optical area includes a transmission area and a non-transmission area including light emitting areas. At least one first type signal line extending through the optical area among the signal lines includes a transparent line part in the transmission area of the optical area and a non-transparent line part in the non-transmission area of the optical area. The transparent and non-transparent line parts are in different layers. Through the foregoing configuration, the transmittance of the first optical area with which a first optical electronic device is overlapped can be improved.

Abstract: A display apparatus may include a display panel including a first area corresponding to a first resolution, a second area corresponding to a second resolution lower than the first resolution, and a third area corresponding to a third resolution lower than the second resolution, and a sensor disposed under the panel to overlap at least a portion of the third area. Pixels are disposed in the first area based on a first arrangement corresponding to a first pixel group including sub-pixels. Pixels are disposed in the second area based on a second arrangement corresponding to a second pixel group in which at least one of the sub-pixels of the first pixel group is omitted. Pixels are disposed in at least a part of the third area based on the first arrangement. A light transmittance portion is disposed in another part of the third area.
