METHOD FOR PRODUCING EL DISPLAY DEVICE, TRANSFER SUBSTRATE USED IN PRODUCTION OF EL DISPLAY DEVICE, AND METHOD FOR PRODUCING TRANSFER SUBSTRATE USED IN PRODUCTION OF EL DISPLAY DEVICE

摘要

A method for manufacturing an EL display device, the EL display device including: a light-emitter emitting light of at least red, green, and blue colors; and a thin-film transistor array device controlling light-emission of the light-emitter, the light-emitter including at least red, green, and blue light-emitting layers arranged within regions partitioned by banks, and being sealed with a sealing layer, the method including: preparing at least three types of transfer substrates corresponding to red, green, and blue colors, each transfer substrate having a supporting substrate on which a transfer layer including at least red, green, or blue light-emitting material is formed by an inkjet method; and when forming the light-emitting layers, repeatedly performing a transfer process that includes transferring the transfer layer onto a transfer-target substrate of the EL display device by using the transfer substrate.

1. A method for manufacturing an EL display device, the EL display device comprising: a light-emitter that emits light of at least red, green, and blue colors; and a thin-film transistor array device that controls light-emission of the light-emitter, the light-emitter including at least red, green, and blue light-emitting layers arranged within regions partitioned by banks, and being sealed with a sealing layer, the method comprising:
preparing at least three types of transfer substrates corresponding to red, green, and blue colors, 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 by an inkjet method; and when forming the light-emitting layers, repeatedly performing a transfer process that comprises transferring the corresponding transfer layer onto a transfer-target substrate of the EL display device by using the corresponding transfer substrate.
