Abstract:
A light-emitting device that suppresses color unevenness can be provided. A transparent member can be disposed on a fluorescence-containing resin layer. Part of excitation light can be emitted upward from an edge surface of the fluorescence-containing resin layer directly and without passing through the transparent member. Thus, fluorescent light emitted in large quantities from a place near an edge surface of the transparent member can be mixed with the excitation light emitted from the edge surface of the fluorescence-containing resin layer directly without passing through the transparent member, thereby suppressing color unevenness at a location near the edge surface of the transparent member.
