Patent ID: 11402654

Abstract:
A method for manufacturing a stereoscopic image forming device includes a process of molding, from a first transparent resin, molding base materials 22 each including inclined surfaces 17 and vertical surfaces 18 on one side of a transparent plate member 16, a process of manufacturing a pair of intermediate base materials 28 by forming mirror surfaces on the vertical surfaces 18 of the respective molding base materials 22, and a process of manufacturing first and second optical control panels 13 and 14 integrated together by making the pair of intermediate base materials 28 face each other so that their vertical surfaces 18 are orthogonal to each other in a plan view, and joining together the intermediate base materials by filling the grooves 19 with a second transparent resin with a lower melting point than and a refractive index equal or approximate to the first transparent resin.
