Abstract: Provided is a display panel including a plurality of sub-pixels and includes a substrate and a pixel defining layer, a light emitting device and a color film layer disposed on the substrate. The pixel defining includes M layers and M being a positive integer equal to or greater than 2, an m-th layer of pixel defining layer is covered on a surface of an (m−1)-th layer of pixel defining layer, and a refractive index nm-1 of the (m−1)-th layer of pixel defining layer is greater than a refractive index nm of the m-th layer of pixel defining layer, and wherein 2≤m≤M.
