PROBLEM TO BE SOLVED: To suppress the dimensions of a light-emitting device in a surface direction of a surface light source, and the thickness of the light-emitting device.SOLUTION: A light source fixing device 200 is equipped with a base member 201, a coupling member 310 for coupling the base member 201 and a surface light source 100 with each other, a first journal portion 311, and a second journal portion 312. The first journal portion 311 journals one end portion of the coupling member 310 to the base member 201 so as to rotate the coupling member 310 about a first rotation shaft parallel with the surface light source 100. The second journal portion 312 journals the other end portion of the coupling member 310 to the surface light source 100 so as to rotate the coupling member 310 about a second rotation shaft parallel with the first rotation shaft. The coupling member 310 is rotated about the first rotation shaft and the second rotation shaft, and the surface light source 100 and the base member 201 are brought close to each other, thereby attaching the surface light source 100 to the base member 201. |
