  • Method of making LC polymer film
    Patent number: 7727686
    Abstract: To provide a method of making a film of organic material excellent in moisture barrier property and/or oxygen barrier property and also to provide an electronic device excellent in long term stability, in which the film obtained by such film making method is utilized to form a protective film for protecting an electronic device, and particularly an organic electronic device, to avoid deterioration of the performance, which would otherwise be brought about by moisture and oxygen in the atmosphere. The film is formed by depositing and solidifying, on a substrate, an evaporant formed by irradiating a liquid crystal polymer capable of exhibiting an optical anisotropy with pulsed laser.
    Type: Grant
