Abstract: A display panel and a display device are provided. The display panel includes an array substrate, an optical function layer, and an anti-reflection layer. The optical function layer and the anti-reflection layer are located on the array substrate, material of the anti-reflection layer includes a sulfur-containing material, and a refractive index of the anti-reflection layer is between refractive indexes of two film layers adjacent to the anti-reflection layer. Since the refractive index of the anti-reflection layer is between the refractive indexes of the two film layers adjacent to the anti-reflection layer, reflection of external light on the display panel is reduced, thereby improving a display effect of the display panel.
