Abstract

An organic light-emitting device including a substrate, first electrodes, first banks extending in a first direction, second banks extending in a second direction, organic functional layers each including an organic light-emitting layer, and a second electrode. The second banks include an organic fluorine compound, and have portions intersecting with and disposed above the first banks. Each of the first banks includes an organic bank layer including an organic material and an inorganic bank layer disposed on the organic bank layer. For each of the first banks, an uppermost surface thereof is a surface of the inorganic bank layer included therein.
