Abstract: A method including: forming a thin-film transistor array device that constitutes a pixel circuit; forming light-emitting layers; and after forming a light-emitter by forming the light-emitting layers, sealing the light-emitter entirely. The forming of the light-emitting layers includes: preparing transfer substrates, each transfer substrate having a supporting substrate on which a transfer layer including at least one of red, green, and blue light-emitting materials is formed; and transferring the corresponding transfer layer onto a transfer-target substrate of an EL display device by using the corresponding transfer substrate, and the forming of the light-emitting layers, the sealing, and the forming of the transfer layer of each transfer substrate are performed within an isolation atmosphere for preventing exposure to the air.
