Document Type and Number:
Japanese Patent JP4849175
Kind Code:
B2
Abstract:
It is an object to provide a light-emitting device (21) including an organic electroluminescent (EL) element (22), which is capable of preventing generation of a leakage current. This light-emitting device is a light-emitting device including a supporting substrate (11), a partition wall (17) for dividing a plurality of organic EL elements on the supporting substrate, and the organic EL elements provided in a concave portion (18) that is a space between the partition walls, wherein: each organic EL element is constituted by disposing a first electrode (12), a first resistance layer (13) formed by an applying method, a second resistance layer (14) having an electric resistance higher than that of the first resistance layer, a light-emitting layer (15), and a second electrode (16) in this order so that the first electrode is located near the supporting substrate; the first resistance layer includes a creeping-up portion (13a) creeping up to a direction that is away from the supporting substrate and along the surface of the corresponding partition wall; and the second resistance layer is provided by ranging continuously over one organic EL element to another organic EL element that are adjacent to each other with the partition wall interposed therebetween.
