Patent ID: 8304986

Claim:
An organic EL display panel comprising: 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 a substrate edge side is defined as inclination angle α, and an inclination angle of the wall surface of the region on a 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 the edge of the substrate.
