Title:
発光層の形成方法およびそれを用いた有機発光デバイスの製造方法
Document Type and Number:
Japanese Patent JP4984433
Kind Code:
B2
Abstract:
A method for the formation of a luminescent layer having a uniform thickness in a desired pattern and an organic electroluminescent device that can realize high-quality display and is highly reliable. The luminescent layer is formed by providing a blanket having a resin film having a surface tension of not less than 35 dynes/cm as a surface layer and an ink for a luminescent layer, having a viscosity (ink temperature 23° C.) in the range of 5 to 200 cP as measured at a shear rate of 100/sec, and containing a solvent having a surface tension of not more than 40 dynes/cm and a boiling temperature in the range of 150 to 250° C., filling the ink into cells in a gravure form, allowing the blanket to receive the ink from the cells, and transferring the ink on the blanket onto a luminescent layer forming face.
