Abstract
Light emitters are two-dimensionally disposed along a main surface of the substrate. The light emitters each include: a first electrode; an organic light-emitting layer; an intermediate layer; a charge transport layer; and a second electrode. Such layers are disposed in the stated order with the first electrode closest to the substrate. The intermediate layer contains a fluoride of an alkali metal or a fluoride of an alkaline earth metal. The charge transport layer contains an organic material doped with an alkali metal or an alkaline earth metal. The light emitters are partitioned from one another by first banks extending in one direction along the main surface of the substrate and second banks extending in a direction intersecting the one direction. Surface portions of the first banks facing the light emitters have greater liquid repellency than surface portions of the second banks facing the light emitters.
