Abstract
A light emitting device and the production method thereof are provided, which are characterized by low manufacturing costs, low power consumption, and high luminous efficiency. The production method comprises processes of forming a transparent electrode layer above a transparent substrate in order to supply current to a luminous material layer, forming the luminous material layer emitting light by supplying the current thereto on the transparent electrode layer, and forming a reflecting electrode layer on the luminous material layer in order to supply current to the luminous material layer. A plurality of opening is formed in the transparent electrode layer with a predetermined pattern. By the openings, slope sections are formed in the luminous material layer and the reflecting electrode layer. Thereby, it is possible to increase the luminous efficiency of the light emitting device.
