LIGHT EMITTING ELEMENT AND METHOD FOR PRODUCING THE SAME, AND LIGHT EMITTING DEVICE

摘要

In each organic EL element (100a to 100c), a positive electrode (102), a functional layer containing a charge injection and transport layer (103) and an organic light emitting layer (105), and a negative electrode (107) are laminated on a substrate (101) in this order, and the shape of the organic light emitting layer (105) is defined by banks (104). The hole injection and transport layer (103) is a metal oxide layer obtained by oxidizing the surface of the positive electrode (102) composed of a metal layer. Further, the hole injection and transport layer (103) has a recessed portion (recessed structure (103a)) in which an area defined by the banks 104 is embedded, and recessed edges (103c) of the recessed structure (103a) are covered by parts of the bank (104) (covered portions (104d)).
