Method for forming a pattern of an organic thin film of an organic electroluminescence display device

摘要

A donor film (34) for laser induced thermal imaging method having a base film (31), a light-to-heat conversion layer (32) formed on the base film, a reflection layer or a metal layer (35) formed on the light-to-heat conversion layer, and a transfer layer (33) formed on the reflection layer and formed of an organic material. The donor film is capable of reducing an edge open defect and increasing the amount of energy absorbed into the light-to-heat conversion layer by forming either the reflection layer or the metal layer between the light-to-heat conversion layer and the transfer layer, preventing damage of the substrate by not transmitting a laser beam to the substrate and prevents deterioration of the transfer layer by preventing gas generated from the light-to-heat conversion layer by heat from penetrating into the transfer layer and dissipating heat transferred to the transfer layer well into the transfer layer.
