In the present invention, an organic EL device, which includes first and second display electrodes and at least one organic functional layer sandwiched between the respective display electrodes and composed of an organic compound, a high-molecular compound film covering the organic EL device and a surface of a substrate in the periphery of the organic EL device, an inorganic barrier film covering the high-molecular compound film, the edge of the high-molecular compound film, and a surface of the substrate in the periphery of the high-molecular compound film are formed on the substrate. In this case, a aliphatic polyurea film is used as the high-molecular compound film.
