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.
