PROBLEM TO BE SOLVED: To provide an organic LED display with excellent electrical characteristics, by flattening the surface shape of a film made by an ink-jet printer mode, and eliminating a boundary face in an organic layer. SOLUTION: In the case of an organic LED display having an organic layer made up of a luminous layer, or of a luminous layer and a charge transfer layer, this coating liquid for organic layer formation is made up of an organic material necessary for forming the organic layer, or its precursor and a solvent, it has a vapor pressure of 10 mm Hg or less at 20 deg.C in the solvent, and it includes at least one kind of low-volatility liquid solvent having a boiling point not higher than the quality-changing temperature of the organic material or not higher than the transition temperature of the precursor. The method for manufacturing this organic LED display includes a process for forming by an ink-jet mode at least one layer of coating film out of the coating liquid for organic layer formation for an organic LED display, and a process for forming an organic layer by heating and drying the coating film at a temperature not lower than the boiling point of a liquid organic solvent included in the coating liquid and having low volatility at ordinary temperatures.
