A display device which can ensure sufficient adhesive strength between each pair of substrates of a liquid crystal display panel and a sealing material includes: a first substrate having a predetermined integrated circuit; a second substrate on one surface of the first substrate in an overlapping manner; and an adhesive material between the first substrate and the second substrate that has an annular planar shape. The adhesive material adheres the first substrate and the second substrate, wherein an outer periphery of the adhesive material includes a zone which includes a plurality of first portions passing substantially the same position as an outer periphery of the surface of the first substrate and a plurality of second portions each connected with the two neighboring first portions and having a center portion thereof in a peripheral direction retracted toward an inner peripheral side of the adhesive material.
