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 electroluminescence (EL) display panel includes a substrate; first electrodes spaced away from each other and arrayed in rows and columns above the substrate; light-emitting layers including organic light-emitting material and disposed above the first electrodes; a second electrode disposed above the light-emitting layers; a first protection layer including resin and disposed above the second electrode but not within an auxiliary region which, in plan view, extends in a column direction between ones of the first electrodes that are adjacent in a row direction across the substrate; a second protection layer including inorganic material and disposed above the first protection layer and the second electrode; and an auxiliary electrode layer extending in the column direction within the auxiliary region and electrically connecting to the second electrode through a contact opening in the first protection layer within the auxiliary region.
