Abstract:
A light source assembly includes a base substrate, a resin layer disposed on the base substrate, and exposing a portion of the base substrate, and a first light source disposed on the portion of the base substrate which is exposed by the resin layer. The first light source has a hexahedron shape. The first light source has a face in parallel with the base substrate and having a height smaller than length or width of the face.
