Patent ID: 8535108

Claim:
A formation method of an organic layer, comprising: a transfer process of forming an organic layer by superposing a donor substrate having a light heat converting layer and a transfer layer formed sequentially to cover at least regions corresponding to organic layer formation regions on a support plate, a transfer mask having openings corresponding to the organic layer formation regions, and a transfer target substrate on a surface of which an organic layer is to be formed, on one another so that one surface of the transfer mask comes into contact with a transfer layer-side surface of the donor substrate and the other surface of the transfer mask comes into contact with the organic layer formation-side surface of the transfer target substrate, and, in this state, transferring the transfer layer onto the transfer target substrate via the openings of the transfer mask, wherein a surface of the transfer mask facing the transfer layer of the donor substrate is higher in optical reflectance than a transfer mask-side surface of the light heat converting layer.
