Abstract: Provided are a display panel and a display apparatus including the display panel. The display panel includes, sequentially along a light-exiting direction, a substrate, a plurality of light-emitting units located in a main display region and an optical component-arranging region, and a filter layer including a plurality of color resistors. A density of light-emitting units located in the optical component-arranging region is smaller than a density of light-emitting units located in the main display region. The optical component-arranging region includes a plurality of light-emitting regions and a plurality of light-transmitting regions. The plurality of light-emitting units located in the optical component-arranging region is arranged in the plurality of light-emitting regions. In a direction perpendicular to the substrate, some color resistors of the plurality of color resistors overlap the plurality of light-transmitting regions. The invention reduces the reflectivity of the optical component-arranging region and weakens the phenomenon that metals are visible.
