Display device including seal material with improved adhesion strength for bonding two substrates together
A display device includes: a first substrate and a second substrate which are located so that inner main surfaces thereof face each other; a liquid crystal layer located between the first substrate and the second substrate; a seal material located between the first substrate and the second substrate so as to surround the liquid crystal layer, the seal material bonding the first substrate and the second substrate to each other; an organic insulation film located in a seal formation area on the inner main surface of the second substrate, the organic insulation film having an opening section in the seal formation area; and an inorganic insulation film located to continue from an inside of the opening section to a surface of the organic insulation film through an inner wall surface of the opening section, the inorganic insulation film being directly covered with the seal material.
