    Abstract: An organic electroluminescence display includes a transparent glass substrate, an ITO anode layer, a positive hole transition layer, an RGB luminescence layer, an electron transition layer and a metallic cathode layer. Highly pressurized N2 gas is sealed in the interior of the display. To absorb and retain the moisture in the sealed gas, a hygroscopic member is disposed between a sealing member and the cathode layer. The hygroscopic member includes a nonwoven fabric including a fiber layer made of fibers bonding to each other and a hygroscopic agent adhering to one surface of the fiber layer and an air-permeable sheet covering the nonwoven fabric as a whole.
