LIGHT EMITTING DISPLAY DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To manufacture a light emitting display device having a high degree of precision in which polychromic colorization with high color reproduction performance is possible by deploying light emitting elements for three colors or more in a single pixel, and which has a high productivity. SOLUTION: In the light emitting display device in which multi-colored display is carried out by forming a plurality of single pixels p having self-light emitting elements 10 that emit three different colors or more, a self-light emitting element 10 of a first color in the single pixel p has light emitting layers 21C1a, 21C1bwhich are laminated through at least twice of film-forming processes and present the first light emitting color, the self-light emitting element 10 of a second color in the single pixel p has the light emitting layers 21C2a, 21C2bwhich are laminated through at least twice of the film-forming processes and present the second light emitting color, while the self-light emitting element 10 of a third color in the single pixel p has light emitting layers 21C1athat presents the first light emitting color, and light emitting layers 21C1bthat presents the second light emitting color.
