In order to improve the light extraction efficiency of a light-emitting element, the light-emitting element includes: a light-emitting layer provided between an electrode and a transparent substrate; a particle layer provided between the light-emitting layer and the transparent substrate; and an adhesive layer provided between the light-emitting layer and the particle layer, the particle layer includes particles having a refraction index that is higher than a refraction index of the transparent substrate, the adhesive layer has a refraction index that is higher than the refraction index of the transparent substrate, and the particle layer has an average thickness that is less than an average particle size of the particles. |
