Abstract: An optical prism sheet includes a transparent substrate having a light-entrance surface, and a plurality of elongated prisms that protrude from the transparent substrate. Each of the prisms has a scalene triangular cross-section and first and second surfaces that intersect each other to define an apex angle. The apex angle of each of the prisms is divided by a normal line of the transparent substrate into first and second sub-angles that are different from each other. At least one of the light-entrance surface and the first and second surfaces of each of the prisms is roughened to form a plurality of micro-protrusions, each of which has a height ranging from 0.1 μm to 5 μm.

Abstract: An optical thin film includes: a transparent substrate including a first surface and a second surface which is opposite to the first surface; a first light-condensing layer formed on the first surface of the transparent substrate, the first light-condensing layer having a haze value ranging from 5% to 30% and a surface roughness ranging from 0.1 RMS to 1 RMS; and a second light-condensing layer formed on the second surface of the transparent substrate. The second light-condensing layer has a haze value ranging from 70% to 100% and a surface roughness ranging from 1 RMS to 10 RMS.
