Abstract
Provided is a quantum dot composite film. The quantum dot composite film includes a first barrier film, a quantum dot phosphor film disposed on the first barrier film, and a second barrier film disposed on the quantum dot phosphor film, wherein the first barrier film or the second barrier film is a dichroic mirror barrier film. Therefore, since the quantum dot composite film bonded to various optical functional films is provided, the number of optical films requires for a typical thin-film-type lighting apparatus may be effectively reduced.
