Abstract:
1. An organic light emitting device, comprising: a first electrode and a second electrode each of which comprises metal and is formed on a substrate; an electron transport layer on the first electrode; a first partition wall insulating the first electrode from the second electrode and extending onto the electron transport layer along the first electrode; a second partition wall formed on the first electrode around the electron transport layer; a third partition wall separated from the first partition wall and formed on the second electrode; an organic light emitting layer formed on the electron transport layer; a hole transport layer formed on the organic light emitting layer, the hole transport layer covering the first partition wall and contacting an exposed portion of the second electrode between the first partition wall and the third partition wall; a protecting layer covering the hole transport layer, and extending onto the first electrode and the second electrode around the second partition wall and the third partition wall; and a sealing material filling spaces between the protecting layer and the first electrode and the second electrode.
