Abstract: A light emitting unit is provided. The light emitting unit comprises a substrate, a light emitting element placed on a first surface of the substrate, a front panel covering the first surface, and a back panel placed on a second surface of the substrate, which is opposite to the first surface. An opening for extracting light emitted by the light emitting element is formed in the front panel, and the opening is formed to overlap a part of a light emitting surface of the light emitting element. The back panel has a thermal conductivity higher than that of the front panel, and includes a projecting portion that projects toward the first surface. The projecting portion is in contact with at least one of the first surface, the light emitting element, or the front panel.
