<P>PROBLEM TO BE SOLVED: To provide a surface light-emitting body which has excellent storage stability under a high temperature environment wherein unevenness of in-plane brightness is reduced by improving front brightness. <P>SOLUTION: In a surface light-emitting body having at least a surface light-emitting element having a transparent substrate and a dimming block, the dimming block has a plurality of protruding parts on at least one side, the tip parts of the protruding parts are in contact with an emitting face of the surface light-emitting element in a manufacturing method of the surface light-emitting body. The manufacturing method of the surface light-emitting body has: a process of floating a substrate of the surface light-emitting element in the resin vessel so that the emitting face of the light-emitting element may be in contact with the liquid resin vessel; and a process of photo-curing the resin to form the protruding parts by scanning a light beam along formation of the protruding parts to be formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
