Abstract
A donor substrate for use in a Laser Induced Thermal Imaging method includes a transfer film that includes a light-emitting layer made up of a host substance that includes a matrix material and a low molecular weight transporter, and a phosphorescent dopant. The transfer film is transferred in the formation of an organic EL device which includes a first electrode, a hole transport layer, a light-emitting layer, and the second electrode, wherein the light-emitting layer includes the light-emitting film. Accordingly, the light-emitting layer can be patterned, and a color purity and light emitting characteristics of a full color organic polymer EL device, produced through a laser induced thermal imaging operating, can be improved.
