PROBLEM TO BE SOLVED: To provide a light-emitting device that can enhance inner-face accuracy of a housing space formed in light guide plates for housing a light source, and thereby, with a distribution of emitting light from the light guide plate uniformalized.SOLUTION: The light-emitting device 1 includes: a light source 3A having an element-mounting substrate 33; LED elements 32 mounted on the element-mounting substrate 33, and a glass sealing part 34 for sealing the LED elements 32 on the element-mounting substrate 33; and light guide plates 2A, 2B made of a platy translucent member and having concave parts 20a, 20b housing at least a part of the light source 3A. The concave parts 20a, 20b are formed in notching to extend in a thickness direction of the light guide plates 2A, 2B from rear faces 23 toward surfaces 22 of the same 2A, 2B at positions corresponding to the light sources 3A in an extension direction of end faces 21a, 21b of the light guide plates 2A, 2B. The light source 3A has side faces 34b emitting light in a direction orthogonal to an optical axis parallel with the thickness direction of the light guide plates 2A, 2B. |
