To provide a full color display organic EL display device with improved light emission efficiency, and manufacturing method of the same.
A lower electrode 41 is formed on a color filter 30, and a first organic light emitting unit 431 emitting monochromatic light, and a fourth organic light emitting unit 437 emitting composite color light by itself or by combination, are formed respectively on the lower electrode. The first organic light emitting unit is located upside of a first resist 351 of the color filter corresponding to monochromatic light, and the fourth organic light emitting units are located upside a second resist 353 and a third resist 355 of the color filter corresponding to three primary colors respectively, to transmit three primary colors and display in full color. Filter transmission efficiency of the first organic light emitting unit is high, since it is light emission of one color of three primary colors, therefore, the size of light emission area and filter area of the other two colors can be enlarged by reducing the area of the first organic light emitting unit in accordance with its brightness. Further, the process for forming the light emitting unit and the filter can be reduced.
