  • Patent number: 10162213
    Abstract: A method of producing a polarizing light-emitting film using photoluminescent ferroelectric liquid crystal molecules, and a liquid crystal display including the polarizing light-emitting film, are described. The method includes forming a droplet by positioning photoluminescent ferroelectric liquid crystal molecules on a substrate modified to be molecular phobic, and applying an electric field in a horizontal direction to uniaxially orient the liquid crystal molecules. By such method, it is possible to produce the polarizing light-emitting film in which the photoluminescent ferroelectric liquid crystal molecules are uniaxially oriented to simultaneously act as the liquid crystal layer, the polarizing plate, and the color filter. The liquid crystal display including the polarizing light-emitting film is capable of improving polarization and contrast, and implementing colors even without a polarizing plate and color filter, thereby increasing light efficiency and power efficiency and reducing production cost.
