Abstract:
PURPOSE: A gap filling method of a nanostructure and a manufacturing method of an organic light-emitting device(OLED) using thereof are provided to form an oxide thin film with a flat surface by pressing a gap of the nanostructure with a mold. CONSTITUTION: A gap filling method of a nanostructure comprises the following steps: supplying a substrate with the nanostructure including a gap on the upper side(S1); spreading a coating composition to fill the gap(S2); pressing the layer of the coating composition with a mold(S3); irradiation ultraviolet rays to the coating composition layer(S4); heating the layer to form a metal oxide thin film; and separating the mold from the metal oxide thin film(S5).

PURPOSE: A patterning method of a metal oxide thin film using nano-imprint and manufacturing method of a light emitting diode are provided to reduce a pattern process by removing a process of covering an ultraviolet resin additionally. CONSTITUTION: A photosensitivity metal-organic precursor solution is coated on a substrate(S1). A photosensitivity metal-organic precursor coating layer is pressurized into a patterned mold(S2). Ultraviolet ray is radiated on the pressured metal-organic precursor coating layer to form a hardened metal oxide film pattern(S3). The patterned mold is removed from the metal oxide thin film pattern(S4). A plastic process of processing the metal oxide thin film pattern with a thermal process is performed.
Abstract:
A method for manufacturing an organic light emitting device is provided to improve photonic efficiency by including a photonic crystal structure. A photonic crystal layer is formed on a substrate(10). An intermediate layer(60) having the high refractive index in comparison with the photonic crystal layer(50) is formed on the photonic crystal layer. A first electrode layer(20), a light-emitting layer(30), and a second electrode layer(40) are successively formed on the intermediate layer. The photonic crystal layer material is coated on the substrate. The photonic crystal is formed by imprinting the photonic crystal layer material with a mask having an reverse surface shape.
