Abstract
Provided is an organic light emitting device comprising: a substrate; and a plurality of sub-pixels, each sub-pixel comprising a thin film transistor formed on the substrate; a planarization layer formed on the thin film transistor, and having a contact hole exposing a portion of a source electrode or a drain electrode of the thin film transistor; a contact electrode formed on the planarization layer, and electrically connected with the source electrode or the drain electrode of the thin film transistor through the contact hole; a first electrode spaced apart from the contact electrode, the first electrode formed on the planarization layer; an insulating layer formed on the first electrode and the contact electrode, the insulating layer comprising a first opening exposing a portion of the first electrode and a second opening exposing a portion of the contact electrode; a light emitting layer formed in the first opening; a second electrode formed on the light emitting layer and electrically connected with a portion of the contact electrode through the second opening.
