ABSTRACT:
A display device which can ensure a sufficient adhesive strength on an adhering surface between each of a pair of substrates of a liquid crystal display panel and a sealing material is provided. A display device includes: a first substrate on which a predetermined integrated circuit is formed; a second substrate which is arranged on one surface of the first substrate in an overlapping manner; and an adhesive material which is arranged between the first substrate and the second substrate and has an annular planar shape as viewed from the surface of the first substrate, the adhesive material being provided for adhering the first substrate and the second substrate, wherein an outer periphery of the adhesive material as viewed from the surface of the first substrate includes a zone which is constituted of 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 of which is connected with the two neighboring first portions and has a center portion thereof in a peripheral direction retracted toward an inner peripheral side of the adhesive material as viewed from the surface of the first substrate.
