In an organic EL display, wherein anodes, cathode connection terminals, an insulating film, partition walls, organic compound layers and cathodes are provided on a substrate, the insulating film has apertural areas formed in positions serving as display pixels, and first structure is provided so as to surround connection positions between the cathodes and the cathode connection terminals in a region outside an endmost anode, the first structure avoids the formation of a resistor by preventing an organic material solution from flowing in the first structure when the organic material solution is applied.

Organic EL display and method for producing the same

On a substrate, a color filter each comprising color layersA,B,C of three primary colors (red, green and blue) and a liquid-material-spreading preventive memberare formed, the liquid-material-spreading preventive member being disposed at the regionoutside the anode wire formed at the outermost side. Then, a protective layer, anodesand cathode supplementary wiresare formed on the substrate and an insulation filmis formed thereon. In the insulation film, openingsare formed at positions corresponding to display pixels. Partition wallsare formed on the insulation filmand 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. After thin organic compound layers are formed, cathode wiresare formed.
