ABSTRACT:
When attaching a substrate with an EL element formed thereon and a transparent sealing substrate, the periphery of a pixel portion is surrounded with a first sealing agent that maintains a gap between the two pieces of substrates, an entire surface of the pixel portion is covered with a second transparent sealing agent so that the two pieces of substrate is fixed with the first sealing agent and the second sealing agent. Consequently, the EL element can be encapsulated by curing the first sealing agent and the second sealing agent without enclosing a drying agent and doing damage to the EL element due to UV irradiation even when a sealing device only having a function of UV irradiation is used.
