A display panel includes a substrate and an encapsulation layer disposed on the substrate. Through disposing a refraction piece in a thin film encapsulation layer at a peripheral area of the display panel, having the refraction piece being disposed in a first encapsulation organic layer of the encapsulation layer, and refracting light through an opening of the refraction piece to a display area when light at the peripheral area passes through the substrate, display brightness at a place of the display area close to the peripheral area is increased.
