Abstract: An optical film includes a first pattern layer including a base part and a plurality of protruding parts disposed on the base part, and having a first refractive index, and a second pattern layer disposed on the first pattern layer and having a second refractive index greater than the first refractive index. Each of the protruding parts includes a bottom surface adjacent to the base part, an upper surface opposite to the bottom surface and parallel to the bottom surface, and a side surface disposed between the bottom surface and the upper surface. The side surface includes three or more sub-inclined surfaces, inclination angles of which are different from each other, or includes a curved surface which is convex in a direction of the second pattern layer.

Abstract: A light guide plate receives light and guides the light to a display panel. The light guide plate includes a body and protruding portions. The body includes a first side surface disposed adjacent to the light source, a second side surface facing the first side surface, and an upper surface. Protruding portions are protruded from the upper surface. Each of the protruding portions includes first and second protruding portions sequentially arranged from the first side surface to the second side surface. A width of the first protruding portion in a direction substantially parallel to the first side surface becomes smaller as a distance from the first side surface becomes larger, and a width of the second protruding portion in the direction substantially parallel to the first side surface becomes larger as the distance from the first side surface becomes larger.
