摘要：
An optical lens includes an array of lens units. Each lens unit includes a main body, a light diverging portion and a light converging portion. The main body includes a light incident surface and a light emitting surface opposite to the light incident surface. The light diverging portion is configured for expanding a light field along a first direction, and the light converging portion is configured for compressing a light field along a second direction. The light diverging portion and the light converging portion are both formed on one of the light incident surface and the light emitting surface.
