Abstract
A light-emitting device includes a light-emitting element mounted on a base substrate, a reflective member that is formed on the base substrate and surrounds the light-emitting element, a transparent member that has a flat upper surface and is placed to cover above the light-emitting element, and a DBR film placed on the upper surface of the transparent member. A relation between an incident angle of light emitted from the light-emitting element and input into the DBR film and a transmittance of the light to pass through the DBR film is obtained such that a peak of the transmittance is in a range of the incident angle greater than 0°.

A light-emitting device, comprising:
- a light-emitting element mounted on a base substrate;
- a reflective member that is formed on the base substrate and surrounds the light-emitting element;
- a transparent member that has a flat upper surface and is placed to cover above the light-emitting element;
- and
- a DBR film placed on the upper surface of the transparent member,
- wherein a relation between an incident angle of light emitted from the light-emitting element and input into the DBR film and a transmittance of the light to pass through the DBR film is obtained such that a peak of the transmittance is in a range of the incident angle greater than 0°.
