Abstract: A display panel comprises an optical area included in a display area displaying an image and transmitting light, and a normal area included in the display area and located outside the optical area. A liquid crystal layer may be in the optical area and the normal area, and the display panel may include a first color filter on one side of a substrate in the optical area and the normal area, a compensation layer on one side of the substrate and in the optical area, and a second color filter on the compensation layer in the optical area. In this case, it is configured that a height of the first color filter is greater than a height of the second color filter, thereby enabling normal display operation in an optical area overlaping an optical electronic device.
