Abstract
An organic EL panel comprises anodes, a cathode, organic light-emitting layers, and first functional layers each including a hole injection layer and a hole transport layer. The hole injection layer of each of the R, G, and B colors is made of only a metal oxide including tungsten oxide, and has a thickness of 5 nm to 40 nm. At least one of the hole injection layers has a thickness different from the other hole injection layers. The hole transport layers of the R, G, and B colors are equivalent in thickness. The organic light-emitting layers of the R, G, and B colors are equivalent in thickness.
