Abstract: PROBLEM TO BE SOLVED: To provide an electro-optical device which has no unevenness in emission luminance and has a long lifetime, and an electronic equipment.
SOLUTION: A conductive layer 22 having a conductivity higher than that of a common electrode 21 is formed on the common electrode 21 so as to contact it. Further, the conductive layer 22 is constituted of iron (Fe) having reduction property. Thereby, since the conductive layer 22 traps moisture and oxygen existing in an element forming layer 10, a pixel electrode 16, a function layer 20, and the common electrode 21 in the surrounding, the moisture and oxygen do not reach the function layer 20.

The bonding is performed on an atom level so as to prevent the intrusion of moisture, oxygen and so on from the outside and to achieve a remarkable sealing effect. A longer life of the display part 1 made of, for example, an organic EL element, is thereby achieved.
