Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic electroluminescence (EL) panel, comprising: anodes that are disposed in one-to-one correspondence with red (R), green (G), and blue (B) colors and reflect light; a cathode that is disposed to face the anodes and transmits light therethrough; organic light-emitting layers that are disposed between the anodes and the cathode, correspond one-to-one with the R, G, and B colors, and each emit light due to voltage application between the anode…
