Abstract
A donor substrate for transfer is disclosed. In some embodiments, the donor substrate for transfer includes a base layer, a light-heat conversion layer on the base layer, an intermediate layer on the light-heat conversion layer, and a transfer layer on the intermediate layer, in which the intermediate layer includes a transfer part and a non-transfer part, and in the transfer part and the non-transfer part, surface roughness of the intermediate layer is in a range of 30 nanometers or more and 1 micrometer or less. Methods of manufacturing an organic light emitting diode display are also disclosed.
