PRINTING APPARATUS FOR COATING ORGANIC EMITTING LAYER OF POLYMER ORGANIC ELECTROLUMINESCENCE DEVICE

摘要

PURPOSE: A printing apparatus is provided to allow the polymer organic layer to have a sharp edge, while increasing the thickness of the polymer organic layer. CONSTITUTION: A printing apparatus comprises a doctor roll(111), an anilox roll(113) and a printing roll(115) having a resin plate(117) attached thereto. When a polymer organic material is injected to the anilox roll, the doctor roll contacts the anilox roll so as to apply the injected polymer organic material to the surface of the anilox roll. The anilox roll contacts the printing roll so as to transfer the polymer organic material to the resin plate attached to the printing roll. The resin plate has a surface on which a plurality of embossed patterns are formed. The embossed pattern includes a convex portion and three or more concave portions.
