A method of fabricating an organic electroluminescence display device, comprising the steps of:
- forming a first electrode;
- forming an emissive layer on the first electrode using a solvent and a polymer, the solvent having a surface tension less than 30 dyne/cm and a boiling point greater than 200 degrees centigrade, wherein the polymer is dissolved in the solvent;
- and
- forming a second electrode on the emissive layer.
A method of fabricating an organic electroluminescence display device, comprising the steps of:
- forming a first electrode;
- forming an emissive layer on the first electrode using a solvent and a polymer, the solvent including a first material, a second material and a third material, the polymer having a solubility greater than about 1 percent weight per volume in the first material, the second material having an evaporation rate less than 0.1 fractional weight per minute, the third material having a surface tension less than 30 dyne/cm;
- and
- forming a second electrode on the emissive layer.
