Abstract
A light emitting module includes: a light emitting element unit including: a light-emitting element that has a main-light-emission surface, an electrode-formation surface and a side-surface, a light-transmissive member that covers the main-light-emission surface, and a first light-reflection member that covers the side-surface; a light-transmissive light guide plate including a first main-surface as a light emission surface, and a second main-surface opposed to the first main-surface and has a recess accommodating the light emitting element unit so that the first light-reflection member is partially arranged out of the recess in a cross-section; a light-transmissive interposition member that contacts an interior side-surface of the recess and an exterior side-surface of the light emitting element unit; and a second light-reflection member that partially covers the second main-surface and the interposition member. The interposition member is at least partially exposed from the second light-reflection member in a plan view. The hardness of the interposition member is lower than a hardness of the first light-reflection member and a hardness of the second light-reflection member.
