PROBLEM TO BE SOLVED: To provide a three-dimensional light-emitting structure formed of an extremely thin, light and simple mechanism, applying a sheet member of organic and inorganic electroluminescence which emits surface light, and showing effect of wider light diffusion and more excellent visibility than a two-dimensional light-emitting structure using the sheet member.SOLUTION: A three-dimensional light-emitting structure having several strips of arc-shaped divided cuts not being in contact or intersecting with each other, for a sheet member of organic and inorganic electroluminescence which emits surface light. The three-dimensional light-emitting structure is formed to be expandable and contractible, with a surface having the cuts vertically twisting and expanding by vertically separating a center part and an outer periphery part of the sheet member. |
