Patent ID: 8072571

Claim:
A display device, comprising: a first substrate and a second substrate opposed to each other; and a rectangular frame-shaped sealing material configured to bond the first substrate and the second substrate together, wherein the first substrate has an interconnect layer formed to overlap a corner of the sealing material, a layered insulating film including an inorganic insulating film and an organic insulating film stacked one upon the other to overlap the interconnect layer, and a transparent conductive layer formed on the layered insulating film to be connected to the interconnect layer via a contact hole formed through the layered insulating film, the second substrate has an electrode layer connected to the transparent conductive layer via a conductive particle contained in the sealing material, the inorganic insulating film has an exposed portion exposed from the organic insulating film at the corner of the sealing material, the exposed portion is entirely exposed from the transparent conductive layer, and in the exposed portion, a through hole is formed through the interconnect layer, and the inorganic insulating film is formed to cover the through hole.
