Abstract: PURPOSE: An organic electroluminescent device is provided to improve a color rendering index using a fluorescent substance for changing the light generated from a light emitting unit into different wavelength light. CONSTITUTION: A first light emitting unit(230) for emitting first wavelength light is formed on a substrate(210). A first light emitting unit comprises a first transparent electrode(231), a first organic light emitting layer(233), and a second transparent electrode(235). A second light emitting unit(330) for emitting second wave length light is formed on the first light emitting unit. The second light emitting unit includes a third transparent electrode(331), a second organic light emitting layer(333), and a fourth reflective electrode(335). A fluorescent substance(270) receives the light of the first and the second light emitting unit, and changes the light into different wavelength light.
