Abstract: A patterning device performs patterning in manufacture of a display panel in which thin films including an organic film are laminated above a substrate. The patterning device includes a chamber, light transmissive plates, and a laser emitter. The chamber has a light transmissive window including a first light transmissive plate through which a laser beam is transmitted and accommodates a thin film laminated substrate. A second light transmissive plate through which the laser beam is transmitted is in the chamber between the first light transmissive plate and the thin film laminated substrate at a position spaced away from the thin film laminated substrate. The laser emitter is outside the chamber and emits the laser beam towards the thin film laminated substrate, through the first light transmissive plate and the second light transmissive plate, to irradiate and remove a portion of the thin film.

Abstract: An organic light-emitting device having light-emitting portions arranged in two directions along a substrate main surface. Each light-emitting portion, in a first direction intersecting the substrate main surface, includes, disposed via a first insulating layer, a first electrode, an organic laminate, and a second electrode. In a second direction being one of the two directions along the substrate main surface, a non-light-emitting portion is present between adjacent light-emitting portions. The first electrodes of the adjacent light-emitting portions extend into the non-light-emitting portion. A second insulating layer is present between portions of the first electrodes in the non-light-emitting portion, and covers the portions of the first electrodes in the non-light-emitting portion. A height of the second insulating layer from the substrate main surface is lower than a height, from the substrate main surface, of upper surfaces of portions of the first electrodes in the light-emitting portions.

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.
