摘要： A display device includes a first electrode, an outer electrode surrounding the first electrode, a bank overlapping the outer electrode in a plan view, the bank including an opening that exposes the first electrode, a light emitting element disposed on the first electrode and in the opening of the bank, and a second electrode disposed on the light emitting element. The outer electrode may be electrically disconnected from the first electrode upon a bad contact between a light emitting member and the outer electrode. As a result, defective pixels can be repaired.
