A light-emitting device of the present disclosure includes: a first light-guiding plate having a first light incidence surface and a first light emission enhancement surface provided with a first pattern; and a second light-guiding plate having a second light incidence surface and a second light emission enhancement surface provided with a second pattern. The first pattern is a pattern constituted by a plurality of first punctiform sections of which an arrangement pitch changes to cause density of the first punctiform sections to increase as a distance from the first light incidence surface increases, and the second pattern is a pattern constituted by a plurality of second punctiform sections of which an arrangement pitch changes to cause density of the second punctiform sections to increase as a distance from the second light incidence surface increases, and when viewed from the light emission direction, regions provided with the first pattern and the second pattern partially overlap, and directions in which densities of the first pattern and the second pattern increase are opposite to each other. |
