  • Publication number: 20140141283
    Abstract: A method of manufacturing a phosphor resin film and a phosphor resin film manufactured thereby are provided. The method of manufacturing a phosphor resin film includes preparing a polymer slurry by mixing a polymer resin and a latent curing agent in a solvent, spreading the polymer slurry such that it has a film shape, drying the spread polymer slurry to form a semi-hardened resin film, and providing phosphor powder to the semi-hardened resin film. A phosphor resin film includes semi-hardened resin film including a polymer resin and a latent curing agent and phosphors uniformly formed on one surface of the semi-hardened resin film.
