    IPC: G02F1/1337

    Abstract: Provided is a display device. The display device includes a liquid crystal display panel and an optical film disposed above the liquid crystal display panel, the optical film comprising a first pattern layer having a first refractive index and a second pattern layer having a second refractive index different from the first refractive index and disposed on the first pattern layer. The first pattern layer includes a first base part and a plurality of first protrusions. Each of the first protrusions includes a bottom surface adjacent to the first base part, an upper surface facing the bottom surface, and side surfaces between the bottom surface and the upper surface. Each of the side surfaces is perpendicular to the bottom surface and the upper surface.

    Abstract: An optical film includes a first pattern layer including a first base portion and first protruding portions disposed on the first base portion to be spaced apart from each other and having a first refractive index and a second pattern layer disposed on the first pattern layer and having a second refractive index. Each of the first protruding portions includes a first sub-protruding portion having a first width in a cross-section perpendicular to the first base portion, a second sub-protruding portion disposed between the first base portion and the first sub-protruding portion and having a width that increases from the first sub-protruding portion to the first base portion, and a third sub-protruding portion disposed on the first sub-protruding portion and having a width that decreases as a distance from the first sub-protruding portion increases.
