Abstract: An apparatus for manufacturing a display device, includes: a stage; a temperature controlling portion on the stage, and to receive a member seated on the temperature controlling portion; and a jig portion facing the temperature controlling portion, the jig portion to move linearly, and to receive an adhesive member. The jig portion includes: a first support plate; a second support plate facing the first support plate; and a pressurization plate on the first support plate and the second support plate, the pressurization plate to receive the adhesive member thereon. An end of the pressurization plate is spaced further from the member than an end of the first support plate and an end of the second support plate when the member is seated on the temperature controlling portion.

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.
