A light-emitting device includes: a substrate having a principal surface which includes a resist film; a first light-emitting element line mounted above the principal surface; a second light-emitting element line mounted above the principal surface; a first sealing member which is provided on the resist film and seals the first light-emitting element line; and a second sealing member which is provided on the resist film and seals the second light-emitting element line. In the light-emitting device, a color of light which the first sealing member emits as a result of light emission of the first light-emitting element line is different from a color of light which the second sealing member emits as a result of light emission of the second light-emitting element line, and the principal surface includes a region between the first sealing member and the second sealing member in which the resist film is not formed.
