  • Patent number: 7973468
    Abstract: There are provided an organic EL device and a method of fabricating the same. An effective display area on which an anode electrode, an organic luminescence layer and a cathode electrode are formed is sealed by means of a metal can, a glass cap or an organic/inorganic material. A power source is applied to the anode and the cathode electrodes through a power transferring part extended from the effective display area to a non-effective display area. Accordingly, it is possible to reduce the oxidation of the cathode electrode of the organic EL device, thereby preventing the electrical contact characteristics of the cathode electrode from being deteriorated.

    Abstract: Disclosed are an active matrix type organic electroluminescent display device and a manufacturing method thereof. At least two capacitors having different functions from each other are disposed in a vertically stacked structure within a unit pixel region. When a compensation circuit needing two or more capacitors having different functions from each other per pixel is applied, the two or more capacitors are vertically stacked, thereby preventing the aperture ratio from being lowered due to the increase in the number of capacitors within the pixel.
