Abstract
A light module 1 includes a planar light emitting device 2, a wiring board 3, and an optical sheet 4. The wiring board 3 has a hole 8 for accommodating the planar light emitting device 2. The optical sheet 4 holds the planar light emitting device 2 and the wiring board 3 such that the planar light emitting device 2 accommodated in the hole 8 of the wiring board 3 and the wiring board 3 are flush with each other on the light emitting surface side of the light module 1. The optical sheet 4 holds the planar light emitting device 2 and the wiring board 3, and prevents dust and moisture from entering the inside the light module 1. This eliminates the necessity for the light module 1 to include a casing, packing, and the like. Therefore, the thickness of the module can be reduced.
