Planar light-emitting device

摘要

A planar light-emitting device includes a first reflecting surface, a rectangular support disposed adjacent to the first reflecting surface, light sources each including a light-emitting surface and disposed along, at least one side portion of the rectangular support, and a lens including a light-receiving surface disposed to face the light-emitting surfaces of the light sources, and configured to introduce light emitted from the light sources into a space that is demarcated by at least the first reflecting surface and the rectangular support.
