Manufacturing method of self-luminous element, self-luminous display panel and self-luminous element

摘要

PROBLEM TO BE SOLVED: To provide a self-luminous element capable of extending a long life while improving luminous efficiency. SOLUTION: In an organic EL element 2, a pixel electrode 13, an organic light emitting layer 17 arranged above the pixel electrode 13, and an organic light emitting layer 17 arranged above the organic light emitting layer 17 are doped with Yb. A layer 19 and a counter electrode 20 arranged above the functional layer 19 are provided, and the functional layer 19 is composed of a first layer portion 191 on the organic light emitting layer 17 side and a second layer portion 192 on the counter electrode 20 side. The dope concentration of Yb in the first layer portion 191 is lower than the dope concentration of Yb in the second layer portion 192. [Selection diagram] Fig. 4
