OPTIC FILM AND BACKLIGHT MODULE USING SAME
First Claim
1. An optic film comprising a body and a condensation layer, wherein the body is formed by stacking a plurality of substrates, of which at least a first one of the substrates has a surface forming a light incidence surface of the body and a second substrate has a surface forming a light emission surface of the body, the light incidence surface being roughened to form a frosted surface, the condensation layer being arranged on the light emission surface of the body and forming prism-like micro-structures.
