Abstract

Provided is a light-emitting device that makes it possible to emit, with high efficiency, light having higher uniformity. The light-emitting device includes a light source, a wavelength conversion unit, and a wall member. The light source is disposed on a substrate. The wavelength conversion unit includes a wavelength conversion member and a transparent member that contains the wavelength conversion member therein. The wavelength conversion member is disposed to face the light source in a thickness direction and converts first wavelength light from the light source to second wavelength light. The wall member is provided on a substrate and surrounds the light source in a plane that is orthogonal to the thickness direction. A region occupied by the wavelength conversion member is wider than a region surrounded by the wall member, and entirely overlaps with the region surrounded by the wall member in the thickness direction.
