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: Provided is a display apparatus. The display apparatus includes a flexible circuit board including flexible pads, a main circuit board including main pads, and a display panel including a plurality of pixels connected to the flexible circuit board and configured to receive a signal from the driving chip. In each of the flexible pads and the main pads, a portion of the pads is gradually tilted from pads disposed at a center to pads disposed at an outer side among the pads, and a tilted angle of a main pad disposed at the outermost side of the main circuit board is greater than that of a flexible pad disposed at the outermost side of the flexible circuit board.
