<P>PROBLEM TO BE SOLVED: To provide a high-quality and inexpensive surface light source element that is less apt to cause the problem of luminance unevenness and deterioration of organic electroluminescence. <P>SOLUTION: This surface light source element is provided with a light source 1, by using electroluminescence as a light-emitting source, a transparent base material 11, and an outgoing light control plate 6 having a plurality of projecting parts 9 on a surface on the side facing the transparent base material 11. The light source 1 and the transparent base material 11 are tightly attached to each other by an adhesive 12, and the tips of the projecting parts 9 of the outgoing light control plate 6 are tightly attached to the transparent base material 11 by an ultraviolet-curing adhesive 10. <P>COPYRIGHT: (C)2008,JPO&INPIT |
