Abstract
To increase light-extraction efficiency and simplify manufacturing process. An organic EL panel includes: first electrode reflecting incident light; second electrode transmitting incident light therethrough; organic light-emitting layer emitting light of corresponding color among R, G, and B colors; first functional layer including charge injection/transport layer and at least one other layer, and disposed between the first electrode and the light-emitting layer; and second functional layer disposed between the second electrode and the light-emitting layer. The charge injection/transport layers of R, G, and B colors differ in film thickness, the at least one other layers of R, G, and B colors are equal in film thickness to one another, the second functional layers of R, G, and B colors are equal in film thickness to one another, and the light-emitting layers of R and G colors are equal in film thickness, and differ in film thickness from the light-emitting layer of B color.
