Abstract
The present invention provides an optical film. The optical film includes a first light-guiding layer, a second light-guiding layer, and at least one light absorption member. The first light-guiding layer has a first light incident surface, a first light-emitting surface, and an accommodating recessed portion formed on the first light incident surface. The second light-guiding layer is disposed on the first light incident surface, and has a second light incident surface, a second light-emitting surface, and a light-guiding member formed on the second light-emitting surface. Each light-guiding member is disposed on each accommodating recessed portion respectively, and each light-guiding member has a top portion, a bottom portion, and a side surface connecting the top portion and the bottom portion. The side surface of the light-guiding member faces the inner wall surface of the accommodating recessed portion, and the bottom portion of the light-guiding member corresponds to the opening of the accommodating recessed portion. The light absorption member covers the side surface. The first light-guiding layer has a first refractive index, and the second light-guiding layer has a second refractive index less than the first refractive index.
