Claim:
1. A liquid crystal panel, comprising: a first substrate and a second substrate that faces the first substrate; a first insulating film that is formed on a second substrate side of the first substrate; a second insulating film that is formed on the second substrate side of the first insulating film and is formed to include a plurality of films; a liquid crystal layer that is disposed between the second insulating film and the second substrate; a sealing material that surrounds an outer edge portion of the liquid crystal layer; and a plurality of thin film transistors that are insulated by the first and second insulating films, wherein the second insulating film has a groove that is formed at a part or whole of a peripheral edge portion located more inside than a position at which the second insulating film overlaps the sealing material, and has a higher barrier property for gas and/or liquid than the first insulating film at the first insulating film side, and wherein the groove has a bottom formed with the same semiconductor material as a part of a material for forming the thin film transistor.
