Abstract

An exemplary optical plate includes a base and an array of micro-structures. The base includes a first surface and a second surface opposite to the first surface. The micro-structures are provided at the first surface. Each micro-structure includes a base surface substantially coplanar with the first surface of the base and two side surfaces. The base surface has an approximately olive-shaped profile enclosed by two arc-outlines. The two side surfaces extend obliquely from the two arc-outlines and intersect at a ridge of the micro-structure.
