Abstract: Organic light-emitting device including light-emitting portions disposed in two intersecting directions along a substrate main surface. Each light-emitting portion, in a first direction intersecting the substrate main surface, includes first and second electrodes, a charge transport layer, and an organic light-emitting layer, and is partitioned from adjacent light-emitting portions by first banks extending in a third direction being one of the two directions and second banks extending in a second direction being the other of the two directions. Each area between adjacent first banks is covered by the charge transport and organic light-emitting layers extending continuously across the area over the second banks. The first and second banks contain insulating material, a thickness of the second banks is no greater than 20% a height of the first banks, and the second banks have a surface portion contact angle smaller than that of the first banks.

Abstract: An object is to provide an organic light-emitting panel and an organic light-emitting device capable of reducing ink repellence at portions of banks intersecting an insulating layer. Light-emitting units of the organic light-emitting panel are separated by the insulating layer and the banks. The insulating layer is disposed between first electrode units that are adjacent in a first direction, and the banks are disposed between first electrode units that are adjacent in a second direction. Portions of the banks that intersect with the insulating layer extend over the insulating layer in the first direction. Each of the portions of the banks over the insulating layer, in lateral cross-section, have a surface where an inclination angle θ1 and an inclination angle θ2 between the surface and a surface of the insulating layer satisfy θ1>20° and θ2>20°.
