Abstract:
An electrooptical device having a plurality of light-emitting regions includes a substrate, a bank disposed in a region other than the light-emitting regions on the substrate so as to surround the light-emitting regions, and a functional layer disposed in openings surrounded by the bank. The bank includes an upper bank segment and a plurality of lower bank segments having a higher wettability than the upper bank segment. The number of the lower bank segments exposed is smaller in second regions of the openings than in first regions of the openings.
