PROBLEM TO BE SOLVED: To provide an optical laminated body that the number of parts can be reduced to simplify the assembling work of parts in the production of a surface light-emitting device, the number of optical interfaces in the optical system can be reduced as much as possible, to effectively prevent optical loss due to the interfacial reflection, and the luminance of a surface light-emitting device can be improved. SOLUTION: The optical laminated body 2 includes a polarizing layer 21, first light-transmitting film adhered to the surface of the polarizing layer 21, and a second light-transmitting film adhered to the back face of the polarizing layer 21. The polarizing layer 21 includes a reflection type polarizing film, and both of the first and second light-transmitting films are diffusion films. |
