Wafer level lens, lens sheet and manufacturing method thereof

摘要

A method of manufacturing a lens sheet including following steps is provided. A first structure is provided. The first structure includes a first transparent substrate and a first lens film attached to the first transparent substrate. A second structure is provided. The second structure includes a second transparent substrate and a second lens film. The second transparent substrate has a first surface and a second surface opposite to the first surface. The second lens film is attached to the first surface. The first lens film is attached to the second lens film. A third lens film is formed on the second surface of the second substrate after the first lens film is attached to the second lens film. Moreover, a lens sheet and a wafer level lens are also provided.
