Provided is a light emitting device that suppresses reabsorption between phosphors and realizes excellent light emission efficiency. A light-emitting element mounted on a substrate, a red phosphor layer having a semicircular shape with a diameter r formed on the light-emitting element, and containing a red phosphor of the following formula (1): , (M 1-x1 Eu x1 ) a Si b AlO c N d (1) (wherein M is a group IA element, a group IIA element, a group IIIA element, a group IIIB element excluding Al, a rare earth element, and a group IVB X1, a, b, c and d are elements selected from the elements: 0 <x1 <1, 0.55 <a <0.95, 2.0 <b <3.9, 0 <c < 0.6, 4 <d <5.7), a transparent resin intermediate transparent layer 22 formed on the red phosphor layer and having a semicircular shape of diameter d, and formed on the intermediate transparent layer, a semicircle And a green phosphor layer 24 containing a green phosphor, and the relationship between the diameter r and the diameter d satisfies the following formula (2). r (μm) ≦ d ≦ (r + 1000) (μm) (2) [Selection] Figure 1 |
