Abstract

PURPOSE: To provide a process for manufacture of good workability by repeatedly forming and arranging micro-convex parts on one side, making unevenness in the condensing portions and the regions other than the condensing portions of the other side and shading the regions other than the condensing portions.
CONSTITUTION: Micro-covex parts 1 are formed on one side 2a of a transparent plate to make convex lenses. On the other hand, unevenness is formed by the regions including the condensing portions and the regions other than these on the other side 2b of the transparent plate. Shading films 4 are deposited on these portions which are not the condensing regions. The deposition of the shading films 4 on the convex parts may be accomplished by offset printing or the like, and the deposition on the concave parts simply by coating a slurry over the entire surface and wiping away the portions stuck on the convex parts. The convex lenses 1 of the front side and back side having beforehand formed at an accurate pitch on the transparent plate and the shading films 4 are formed accurately on the convex or concave parts. The drawbacks with the conventional methods of forming shading films on plane that it was difficult to unify the pitches are completely eliminated.
