Abstract
In an organic EL display device, a taper angle of a separation layer surrounding edges of an organic EL layer disposed in each pixel and being disposed between adjacent pixels is different from a taper angle of a frame-shaped bank surrounding edges of an organic layer. As a result, qualities required for layers surrounded by the separation layer and the frame-shaped bank respectively are satisfied.
