Abstract
Disclosed is an organic EL display panel which includes: a substrate; a plurality of linear luminescent regions formed on the substrate, the luminescent regions running in parallel to one another; and two or more sub-pixels arranged in a row in each of the luminescent regions; wherein the luminescent regions include a luminescent region having the sub-pixels emitting red light, a luminescent region having the sub-pixels emitting green light, and a luminescent region having the sub-pixels emitting blue light, each of the sub-pixels includes a pixel electrode disposed on the substrate, an organic functional layer disposed on the pixel electrode by coating, a counter electrode disposed on the organic functional layer, and a forward tapered bank which constitutes wall surfaces of a region in which the organic functional layer is formed, and when an inclination angle of the wall surface of the region on the substrate edge side is defined as inclination angle α, and an inclination angle of the wall surface of the region on the substrate center side is defined as inclination angle β, inclination angle α is smaller than inclination angle β in sub-pixel X in luminescent region X provided at…
