Title:
燐鉱材料の混合物を発光材料として使用した高分子有機電界発光素子
Document Type and Number:
Japanese Patent JP4053929
Kind Code:
B2
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.
