    Abstract: A display panel and display device are provided that may be capable of sensing an external light source, such as a laser. The display device may include a display panel including gate lines, data lines, and sub-pixels defined at intersections between the gate lines and the data lines; a light source-sensing circuit in an inactive area of the sub-pixels to sense an external light source; and a monochromatic color filter pattern disposed on a sensor transistor of the light source-sensing circuit. Thus, the incident amount of an external light source other than a laser can be reduced, and the incident amount of the laser can be increased. Accordingly, it may be possible to decrease an initial off-current caused by an external light source and improve the sensitivity in laser sensing. Thus, the size of the sensor transistor can be reduced and aperture ratio can be increased.

    Abstract: A display device comprises a substrate including a plurality of pixel areas that are spaced apart from each other and a plurality of transmissive areas between the plurality of pixel areas, wherein each of the plurality of pixel areas includes a plurality of sub pixels; and a plurality of signal lines that extend in a first direction on the substrate, wherein the plurality of sub pixels include a plurality of pixel circuits, wherein the plurality of signal lines overlap the plurality of pixel circuits without the plurality of signal lines overlapping the plurality of transmissive areas. Accordingly, the plurality of pixel areas and the plurality of signal lines are in the same area to reduce the size of the opaque area in the entire display device and enlarge a size of the transmissive area to implement a transparent display device.
