Donor substrate for laser induced thermal imaging and method of fabricating organic light emitting diode using the same
Provided are a donor substrate for laser induced thermal imaging (LITI) and a method of fabricating an organic light emitting diode (OLED) using the same, which can prevent a transferred emission layer from being damaged by heat and thus prevent wrinkles from forming on the surface thereof. The donor substrate includes a base layer, a light-to-heat conversion layer disposed on the base layer, a first transfer layer disposed on the light-to-heat conversion layer and including an organic layer, an inorganic layer, or a double layer thereof, and a second transfer layer disposed on the first transfer layer and including an emission layer. The first transfer layer has an absolute value of lowest unoccupied molecular orbital energy level of 2.6 to 3.0 eV and a band gap energy of 2.8 to 3.4 eV.
