METHOD FOR MANUFACTURING DISPLAY DEVICE AND APPARATUS FOR MANUFACTURING DISPLAY DEVICE

WIPO Patent Application WO/2020/065967

A1

This method for manufacturing a display device comprises: a sweeping step; a contacting step; and an electrodeposition step. In the sweeping step, at least one of an electrodeposition head (6) and a substrate (C) relatively moves. In the contacting step, an electrodeposition liquid (L1) containing a functional material supplied from an electrodeposition supply port (20A) contacts the surface of the substrate in an area smaller than the area of the substrate. In the electrodeposition step, a first potential is applied to the electrodeposition head electrode. Among at least substrate electrodes (E1, E2, E3) that are in contact with the electrodeposition liquid, a second potential is applied to the substrate electrodes (E2, E3) that do not electrodeposit the functional material, and a third potential is applied to the substrate electrode (E1) that electrodeposits the functional material. An absolute value of a difference between the first potential and the third potential is larger than an absolute value of a difference between the first potential and the second potential.
