Abstract

An organic EL panel is discloses that includes a substrate and a segment display section provided on the substrate. The segment display section includes an organic EL light emitting section and plural kinds of color modulating sections. The organic EL light emitting section has a single reflective electrode, an organic EL layer, a shadow mask having a plurality of openings, and a single transparent electrode. The plural kinds of color modulating sections are arranged adjacent to the substrate, and each of the plural kinds of color modulating sections is divided into a plurality of subsections. Each of the plural kinds of color modulating sections can be composed of either a color filter layer or a laminated structure of a color filter layer and a color conversion layer. Emitting color of the segment display section can be adjusted by the positions and number of the openings arranged in the shadow mask.
