Abstract

A method for manufacturing a light distribution member has steps of providing a plurality of first light blocking film members, each of which including a first light blocking film covering a surface of a light-transmissive board, bonding a plurality of first light blocking film members, such that each first light blocking film is sandwiched between light-transmissive boards of adjacent first light blocking film members, to form a first bonded body, and cutting the first bonded body in a direction perpendicular to a lamination surface of the first light blocking film members so as to form a plurality of slices.
