| description | To provide an electroluminescent display device with a large area and high resolution.SOLUTION: An electroluminescent display device according to the present invention includes a substrate, a first electrode existing over the substrate, a connection pattern formed of the same material as the first electrode over the substrate, a bank covering an end part of the connection pattern and the first electrode, a light-emitting layer existing over the first electrode, a second electrode existing over the light-emitting layer, the bank, and the connection pattern, and an auxiliary pattern between the second electrode and the connection pattern. The auxiliary pattern includes metal oxide or a conductive nanoparticle. Therefore, when the light-emitting layer is formed by a solution process, the variation between nozzles is minimized and the second electrode is connected to the auxiliary electrode through the connection pattern, so that the resistance of the second electrode can be reduced. The auxiliary pattern can improve the electric contact characteristic between the second electrode and the connection pattern.SELECTED DRAWING: Figure 2
【課題】大面積および高解像度の電界発光表示装置を提供する。【解決手段】本発明の電界発光表示装置は、基板と、前記基板の上部に位置する第１電極と、前記基板の上部に、前記第１電極と同じ物質で形成される接続パターンと、前記第１電極および前記接続パターンの端部を覆うバンクと、前記第１電極の上部に位置する発光層と、前記発光層と前記バンクおよび前記接続パターンの上部に位置する第２電極と、前記第２電極と前記接続パターンの間の補助パターンを含み、前記補助パターンは、金属酸化物や導電性ナノ粒子からなる。したがって、溶液工程により発光層を形成するとき、ノズル間におけるばらつきを最小化し、接続パターンを介し、第２電極を補助電極に接続することにより、第２電極の抵抗を下げることができる。また、補助パターンにより、第２電極と接続パターンの間の電気的接触特性を向上させることができる。【選択図】図２ |
