<p>PROBLEM TO BE SOLVED: To provide an organic EL light-emitting device capable of flexibly adjusting color temperature in a high yield by relaxing the coating liquid positional accuracy of a stripe structure and an island structure and suppressing the cost.SOLUTION: An organic EL light-emitting device is characterized in that, on a flat-shaped hole transport layer including a uniform transparent electrode, at least two kinds of luminescent materials having different light-emission peak wavelengths are separately coated and film-formed by a wet method, and between the luminescent materials and on the upper layers, at least one kind of a luminescent material having the light-emission peak wavelength different from those of the luminescent materials is film-formed by a dry film-forming method.</p> |
