Document Type and Number:
WIPO Patent Application WO/2016/060003
Kind Code:
A1
Abstract:
An optical element which comprises: an optical element base; a first light-blocking film that covers a non-optical-path part of the optical element base; a function film that covers an optical path part of the optical element base and the first light-blocking film; and a second light-blocking film that covers a non-optical-path part of the function film. A region of the function film, which is not covered by the second light-blocking film, is transparent and has a recessed and projected structure, and the other regions of the function film have light reflectivity. Consequently, the present invention provides an optical element such as a lens, which has good flare characteristics, while being free from the occurrence of ghost images.
