摘要： 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.

摘要： A printing machine includes: a frame; a flat anilox plate that is fixed to and located on the frame and has a plurality of cells on an upper surface of the anilox plate; an ink supplying tool that supplies the ink onto the upper surface of the anilox plate; a surface plate that is fixed to and located on the frame and on which the substrate is placed; and a printing cylinder that is arranged above the frame and is capable of moving above the frame. The printing cylinder has a flexographic plate. The flexographic plate contacts the upper surface of the anilox plate, receives the ink, and transfers the ink onto the substrate. The flexographic plate is made of an elastic material. The viscosity of the ink is in a range of 51 cP to 200 cP (ink temperature: 23° C.) at the shear rate of the ink is 100/second.
