Abstract: The present invention relates to a transparent electrode, a flexible organic light emitting diode with the same and a manufacturing method thereof. The transparent electrode according to the present invention includes a thin-film-type electrode made of a conductive material with a light transparence; a light extraction sealing layer that is formed on one of two surfaces of the electrode, made of a light transparence material with a refractive index of 1.7-2.3 and a water vapor permeability (WVTR) of 0.01g/m2·day or less, improves the extraction efficiency of the light passing through an inner part to be emitted to the air, and prevent the penetration of moisture and oxygen into the electrode at the same time. According to the present invention, the transparent electrode with a sealing property improves the extraction efficiency of the light passing through an inner part to be emitted to the air, prevents the penetration of moisture and oxygen into the electrode at the same time by controlling the refractive index according to the refractive index of the flexible substrate by forming the light extraction sealing layer made of the light transparence material such as silicon nitride with a refractive index of 1.7-2.3 and a water vapor permeability (WVTR) of 0.01g/m2·day or less formed on the one of two surfaces of the electrode, and replaces an existing DMD electrode. Because there is no need to form a separate sealing layer on the flexible substrate, the efficiency of a manufacturing process is improved, manufacturing costs is reduce, and the efficiency of a device is improved by reducing layers through which light passes and shortening optical paths.
