Abstract
An optical film to visually reduce frame size of individual display units within a single large display includes four film portions connected to each other to form a rectangular frame of each individual display unit. Each film portion has strip-shaped micro-structures of triangular cross-section, and includes a bottom surface, a first side surface, and a second side surface. The bottom surfaces of the micro-structures are connected to each other. The first side surfaces and the second side surfaces are obliquely connected, the second side surface of one micro-structure being at the outermost side of each film portion. Angle θbetween the first side and bottom surface of each micro-structure is less than angle θbetween the first side surface and the second side surface and the sum of first and second angles θand θis less than 90°.
