Abstract

A formation method of an organic layer (13) includes a transfer process of forming the organic layer (13) by superposing a donor substrate (30) having a light heat converting layer (32) and a transfer layer (34) formed sequentially to cover at least regions corresponding to organic layer formation regions on a support plate (31) and a transfer mask (40) having openings corresponding to the organic layer formation regions, on each other so that the transfer layer-side surface of the donor substrate (30) comes into contact with the transfer mask (40), and, with the resultant structure placed above a transfer target substrate (20) so that the transfer mask (40) is on the lower side, transferring the transfer layer (34) onto the transfer target substrate (20) via the openings of the transfer mask (40).
