Abstract
A display device includes pixels disposed on a substrate. Each of the pixels include a pixel circuit layer disposed on the substrate and includes at least one transistor, a first electrode disposed on the pixel circuit layer and electrically connected to the at least one transistor, a bank disposed on the first electrode, the bank including an opening exposing the first electrode, a conductive pattern disposed on a side surface of the bank surrounding the opening of the bank and the exposed first electrode, a light-emitting element disposed on the conductive pattern in the opening of the bank and electrically connected to the first electrode, and a second electrode disposed on the light-emitting element. The conductive pattern is a guide member that guides light emitted from the light-emitting element to an upper portion of the second electrode.
