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.
