Abstract
On a substrate 111, a color filter each comprising color layers 1A, 1B, 1C of three primary colors (red, green and blue) and a liquid-material-spreading preventive member 26 are formed, the liquid-material-spreading preventive member being disposed at the region 31 outside the anode wire formed at the outermost side. Then, a protective layer 4, anodes 101 and cathode supplementary wires 121 are formed on the substrate and an insulation film 122 is formed thereon. In the insulation film 122, openings 123 are formed at positions corresponding to display pixels. Partition walls 100 are formed on the insulation film 122 and a solution of organic material is applied onto the insulation film to form a thin organic compound layer. The spreading of the solution is prevented by the presence of the liquid-material-spreading preventive member 26. After thin organic compound layers are formed, cathode wires 105 are formed.
