Donor film for laser induced thermal imaging method, light emitting device using the same, and method of manufacturing light emitting device
First Claim
1. A method of manufacturing a light emitting device, the method comprising the steps of:
- providing an acceptor substrate;
providing a donor film separated from said acceptor substrate by a predetermined distance and comprising a light to heat conversion layer including a transcription pattern with a predetermined step difference on a base substrate and a transfer layer provided on said light to heat conversion layer including the transcription pattern;
arranging said donor film so that said transfer layer faces the surface of said acceptor substrate; and
radiating a laser onto said donor film to transcribe the transfer layer onto said acceptor substrate.

Abstract
A donor film for a laser induced thermal imaging method capable of improving the optical efficiency of an emission layer, a light emitting device using the same, and a method of manufacturing the light emitting device are provided. The donor film for a laser induced thermal imaging method includes a base substrate, a light to heat conversion layer (LTHC) provided on the base substrate and having a pattern with a predetermined step difference, and a transfer layer provided on the LTHC. It is possible to improve the optical efficiency of the emission layer by patterning the transfer layer using the LTHC having the pattern with a predetermined step difference.
