Abstract: A display panel includes a display area composed of a light-emitting area and a light-transmissive area in which a dark spot defect in the light-transmissive area does not occur. Further, in the display panel, a decrease in transmittance due to light leakage can be prevented, and color mixing between adjacent pixels can be prevented. To this end, a metal layer is disposed at a boundary between the light-emitting area and the light-transmissive area, a metal layer is disposed at a boundary between sub-pixels rendering different colors and adjacent to each other, and a metal layer is disposed at a boundary between two adjacent light-transmissive areas.
