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.
