The object of the present invention is to provide an organic EL device capable of preventing current leakage and maintaining a long lifetime, a high luminance, a high efficiency and a high display quality. Moreover, an allowable dimensional difference between the first pattern and the second pattern is set to a value corresponding to a distance from the first reference position. A second lining layer is then formed on the doped first lining layer. A trigger circuit discharges the flash discharge tube upon a switching operation.
