Abstract
A display panel is provided. The display panel includes an array substrate, an emissive layer, a color filter layer, and a functional material layer stacked together. A refractive index difference between the color filter layer and the functional material layer is greater than or equal to −1 and less than or equal to 0.5. The color filter layer according to embodiments of the present invention not only has satisfactory optical parameters, can decrease reflectivity of the display, but can also be directly formed on the array substrate having the emissive layer, decreasing a thickness of the display panel and not damaging the emissive layer.
