Light emitting device and image display device |
| abstract |
A light emitting device capable of realizing both a wide color gamut and high light emission efficiency is provided. A light emitting device (10) includes a light emitting element (11) that emits blue light, a Mn 2+ activated γ-AlON phosphor (12a) and Eu 2+ activated β sialon that are excited by the blue light and emit green light. A phosphor (12b); and a red phosphor (13) that emits red light when excited by the blue light. The weight ratio of Mn 2+ activated γ-AlON phosphor (12a) to Eu 2+ activated β sialon phosphor (12b) is (Mn 2+ activated γ-AlON phosphor (12a)) / (Eu 2+ activated β sialon phosphor) The weight ratio of (12b) is in the range of 20 to 75.
