Ink for forming a hole injection layer of organic EL display devices and manufacturing method thereof, organic EL display devices, and manufacturing method of the same |
摘要 |
There is disclosed an organic electro luminescence display device comprising a two-dimensional array of pixels comprising organic electro luminescence elements capable of emitting a of color or different plural colors, each of the organic electro luminescence elements being provided with an anode, a cathode, a polymeric luminescence layer located between the anode and the cathode, and a hole injection layer. The hole injection layer is constituted by solid matters containing a donor molecule comprising polythiophene and/or a derivative thereof, and an acceptor molecule comprising polystyrenesulfonic acid and/or a derivative thereof, a concentration of sulfate ion in the hole injection layer is 125 ppm or less, and components having a molecular weight of 110,000 or less is 35% or less based on an entire solid matters, the molecular weight being converted as sodium polystyrenesulfonate in an aqueous gel permeation chromatography measured by using UV of 254 nm in wavelength.
