Abstract
The light emitting layers and the electron transporting layers of R pixels, G pixels, and B pixels are formed to have a stripe shape extending in the column direction. The red light emitting layer and the electron transporting layer in R pixels are formed to be continuous layers using the same mask in a first vapor deposition chamber, the green light emitting layer and the electron transporting layer of G pixels are formed to be continuous layers using the same mask in a second vapor deposition chamber, and the blue-white light emitting layer and the electron transporting layer of B pixels are formed to be continuous layers using the same mask in a third vapor deposition chamber.
