Abstract: Embodiments of this application provide an organic light-emitting display panel and a display apparatus. A functional layer disposed on a first substrate in the organic light-emitting display panel includes an emissive layer and an optical filter layer. A pixel define layer is disposed between adjacent organic light-emitting units in the emissive layer. Black light-shielding blocks and color-blocking blocks in the optical filter layer are alternately arranged. The color-blocking blocks and the organic light-emitting units are disposed in a one-to-one correspondence manner. A region between adjacent black light-shielding blocks covers the organic light-emitting unit in a thickness direction of the organic light-emitting display panel. The pixel define layer is a black light-absorbing layer. The black light-shielding blocks and the color-blocking blocks in the organic light-emitting display panel and the display apparatus provided in embodiments of this application, may cooperate to reduce transmission of visible light from an external environment to an internal film layer of the organic light-emitting display panel, and allow light emitted by the organic light-emitting unit to pass through. Therefore, a reflectivity of the organic light-emitting display panel to external ambient light is reduced, and luminance of the organic light-emitting display panel is not reduced.
