Abstract:
A method of manufacturing an organic EL device comprising 1) a laminate consisting of an opposed pair of electrodes and an organic light-emitting layer sandwiched between the electrodes, 2) a gas-tight housing accommodating said laminate and shielding off the external atmosphere and 3) a desiccating means disposed in isolation from said laminate within said gas-tight housing, the method comprising:forming a sheet-like preformed moisture-absorbing body comprising a desiccant and a resin component outside said gas-tight housing to prevent generation of impurities inside said gas-tight housing, which is generated during the formation of said preformed moisture-absorbing body; and fixing said preformed moisture-absorbing body as desiccating means to at least one inner part of said gas-tight housing.
