Abstract

A light emitting device includes: a first light emitting element and a second light emitting element, each having a peak emission wavelength in a range of 430 nm to 480 nm; a first light transmissive member disposed on an upper face of the first light emitting element and containing a first phosphor; a second light transmissive member disposed on an upper face of the second light emitting element; and an encapsulant covering the first light transmissive member and the second light transmissive member and containing a second phosphor. The first light emitting element and the second light emitting element are configured to be independently driven. A chromaticity of light exiting from the first light transmissive member differs from a chromaticity of light exiting from the second light transmissive member.
