Patent ID: 8823255

Claim:
A method of manufacturing an organic EL display device, which stands for organic electro luminescence display device, comprising: providing a lower electrode every first organic EL element for a blue color and every second organic EL element for another color on a substrate; forming a hole injection/transport layer having at least one of properties of hole injection and hole transport every first organic EL element and second organic EL element on said lower electrode, by utilizing an application method; forming a second organic light emitting layer for another color on the hole injection/transport layer for said second organic EL element by utilizing an application method; forming a connection layer made of a low-molecular material over an entire surface of said second organic light emitting layer and over an entire surface of said hole injection/transport layer for said first organic EL element by utilizing an evaporation method; forming a first organic light emitting layer for a blue color over an entire surface of said connection layer by utilizing an evaporation method; and forming an electron injection/transport layer having at least one of properties of electron injection and electron transport, and an upper electrode in order over an entire surface of said blue light emitting layer in order.
