There is provided an imaging lens including: a transparent substrate; an upper lens disposed on a top of the transparent substrate; and a lower lens disposed on a bottom of the transparent substrate to correspond to the upper lens, wherein one of the upper and lower lenses includes a lens element and a partition wall formed higher than the lens element to surround the lens element. Also, there is provided a method of manufacturing the same. In the imaging lens, the partition wall is replicated together with the lens element on one or both surfaces of the transparent substrate. The partition wall is formed higher than the lens element and has a flat top surface. Therefore, when another lens element is replicated on an opposite surface of the transparent substrate, the previously replicated lens element is prevented from deformation.

A method for manufacturing a wafer scale lens assembly, and a wafer scale lens assembly manufactured by the same are disclosed. The method includes forming a plurality of transmissive regions and a plurality of non-transmissive regions on an object-side surface or an image-side surface of each of first and second lens substrates, forming a plurality of lens elements having refractive power on at least one of the object-side surface and the image-side surface of each of the first and second lens substrates, and stacking the first and second lens substrates, with a spacer interposed between the first lens substrate and the second lens substrate. Accordingly, image quality is improved by preventing undesired light from forming an image on an image plane of an image sensor. The process time is reduced to reduce a manufacturing cost.
