Abstract
A light-redirecting optical film includes a continuous plurality of micro structures. The micro structures have a common bottom surface and each micro structure includes a first curved surface and a second curved surface. The first curved surface is convex towards the second curved surface. The second curved surface rises from the bottom surface. The first curved surface and the second curved surface meet along a top edge. The curvature of the top edges in the optical film is the same. The first curved surface is a total reflecting surface. A narrow frame display device is also presented.
