A sealed structure with high sealing capability, in which a pair of substrates is attached to each other with a glass layer is provided. The sealed structure has a first and second substrates, a first surface of the first substrate facing a first surface of the second substrate, and the glass layer which is in contact with the first and second substrates, defines a space between the first and second substrates, and is provided along the periphery of the first surface of the first substrate. The first substrate has a corner portion. The area of the first surface of the first substrate is smaller than or equal to that of the first surface of the second substrate. In at least one of respective welded regions between the glass layer and the first or second substrate, the width of the corner portion is larger than that of the side portion.
