Abstract:
1. A display device, comprising: a display panel comprising a central axis, a display area and a non-display area disposed outside the display area; an optical film disposed near one side of the display panel, the optical film comprising a microstructure configured to diverge the incident light into the display panel thereby a portion of the incident light near the border between the display area and the non-display area is redirected to travel over the non-display area; and a convex lens disposed near the other side of the display panel, the convex lens comprising a Fresnel structure and being configured to converge the output light from the display panel thereby the output light is redirected to travel approximately parallel to the central axis; wherein the microstructure comprising a plurality of first inclined surfaces is formed on a surface of the optical film facing away from the display panel and a planar surface is disposed on the other opposite surface of the optical film, and tilt angles θ where n
