PROBLEM TO BE SOLVED: To reduce power consumption even when copper phthalocyanine(CuPc) organic film is made thick, to drive it with a lower voltage for low power consumption, to improve the transmission factor of the red section of visible light through the CuPc organic film and to obtain a desired luminescence color. SOLUTION: An anode 4 made of a transparent conductive film 3 in the prescribed pattern shape is formed on a glass substrate 2. A hole injection CuPc organic film 5a is formed on the anode 4 as a plasma polymerized film having an improved transmission factor of red luminescence at the thickness of 1μm or above by an ion plating method. The CuPc organic film 5a is exposed to the atmosphere of NO2 which is an electron-acceptive gas after it is formed, and it contains NO2 in it. The conductivity of the CuPc organic film 5a is increased, and hole injection efficiency is stabilized and improved. Anα-NPD organic film 5b and an Alq3 organic film 5c are formed in this order on the CuPc organic film 5a to obtain an organic layer 5, and a cathode 6 is formed on the Alq3 organic film 5c. A container section is fixed to the peripheral portion of the glass substrate 2 to protect the anode 4, organic layer 5 and cathode 6.
