Abstract:
A microlens array is provided, including a base layer with a plurality of first microlenses formed over a first region thereof, wherein the first microlenses are formed with a first height. A plurality of second microlenses are formed over a second region of the base layer, wherein the second region surrounds the first region and the second microlenses are formed with a second height lower than the first height. A plurality of third microlenses are formed over a third region of the base layer, wherein the third region surrounds the second and three regions, and the microlenses are formed with a third height lower than the first and second heights.
