ORGANIC ELECTROLUMINESCENT DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To ensure insulation between second electrodes formed on an organic EL layer or that between second and first electrodes and to ensure sealing of an organic EL film contributing to emission even if it is sealed with a thin film. SOLUTION: This organic EL display panel 1 has a plurality of first electrodes 3 formed in the shape of parallel stripes on the surface of a color filter 2. Insulating barrier ribs 4 are formed on the color filter 2 in the shape of parallel stripes perpendicular to the first electrodes 3 while leaving intact an area for forming a plurality of organic EL elements 5 in predetermined positions on the first electrodes 3. The organic EL layer 6 is formed on the first electrodes 3 and the barrier ribs 4, and the second electrodes 7 are formed on the organic EL layer 6. The barrier ribs 4 are made from photoresist and each comprise two reverse-tapered projecting strips 4a and 4b extending parallel to the second electrodes 7, and a forward-tapered insulating layer 8 formed on the outside of the projecting strips.
