1. A display panel without a polarizer, comprising:
a transparent substrate having a light-emitting region and a non-light-emitting region; and
a light-emitting function layer formed on the transparent substrate and located at a side of the transparent substrate, comprising:
a transistor formed on the non-light-emitting region; and
an organic light-emitting device, a part of the organic light-emitting device being formed on the light-emitting region, and another part of the organic light-emitting device being formed on the non-light-emitting region and connected to the transistor; and
a color resist layer formed on the transparent substrate and located on a side of the transparent substrate away from the light-emitting function layer, wherein the color resist layer comprises:
a black matrix formed on the non-light-emitting region; and
a color filter formed on the light-emitting region,
wherein light emitted by the organic light-emitting device is emitted through the light-emitting region of the transparent substrate and the color filter in sequence;
wherein the display panel further comprises a reflective structure formed on the non-light-emitting region, and at least one reflective side of the reflective structure is aligned with a junction of the black matrix and the color filter.
