Abstract
An organic light emitting device including a substrate, a first electrode formed on the substrate and including a recess portion, a partition formed on the first electrode and including an opening exposing the recess portion of the first electrode, an organic light emitting member formed in the recess portion of the first electrode and the opening of the partition, and a second electrode formed on the partition and the organic light emitting member. A gap is formed between a lower portion of the partition and the recess portion of the first electrode and at least a portion of the organic light emitting member is disposed in the gap.
Claims19
An organic light emitting device comprising:
- a substrate;
- a first electrode formed on the substrate, the first electrode comprising a recess portion;
- a partition formed on the first electrode, the partition comprising an opening exposing the recess portion of the first electrode;
- an organic light emitting member formed in the recess portion of the first electrode and the opening of the partition;
- and
- a second electrode formed on the partition and the organic light emitting member,
- wherein a gap is formed between a lower portion of the partition and the recess portion of the first electrode and at least a portion of the organic light emitting member is disposed in the gap.
A manufacturing method for an organic light emitting device, comprising:
- forming a first electrode on a substrate;
- forming a partition having an opening, on the first electrode;
- etching the first electrode by using the partition as a mask to form a recess portion;
- forming a gap under the partition;
- forming an organic light emitting member in the recess portion by filling at least a portion of the gap;
- and
- forming a second electrode on the organic light emitting member.
