摘要： An optical path folding element includes a main body, a light absorption film layer and a matte structure. The main body has optical surface including an incident surface, a reflective surface and an emitting surface. A light enters into the optical folding element through the incident surface. The reflective surface reflects the light so as to change a traveling direction thereof. The light exits the optical folding element through the emitting surface. The light absorbing film layer is configured to reduce reflectance and provided adjacent to at least part of the optical surface, and the light absorbing film layer is in physical contact with the main body. The matte structure is disposed adjacent to at least part of the optical surface. The matte structure provides an undulating profile on a surface of the optical path folding element, and the matte structure is formed in one-piece with the main body.
