Powder desiccant is mixed into a seal which adheres a first substrate to a second substrate, thereby sealing a display region. Almost no moisture permeates through the outer surfaces of the substrates sandwiching the display region, while moisture permeating through the seal is adsorbed by the desiccant. An emissive layer is thereby prevented from deterioration due to moisture. By covering the display region with a resin sealing layer composed of resin having desiccant mixed therein, the display region can reliably be protected from moisture. By forming a groove in the substrate and placing a desiccant therein, moisture can be further reliably adsorbed.
