Patent ID: 8670096

Claim:
A liquid crystal display device, comprising: a pair of substrates arranged opposed to each other via liquid crystal; an insulating film formed on at least one substrate of the pair of substrates up to a vicinity of an end surface of the at least one substrate; and a sealing member for enabling injection of the liquid crystal between the pair of substrates and adhering the pair of substrates to each other, the sealing member including a liquid crystal injecting port through which the liquid crystal is injected, wherein: the insulating film comprises an extension portion, which extends from an end surface of the insulating film at a position which overlaps a portion of the sealing member forming the liquid crystal injecting port, up to the vicinity of the end surface of the at least one substrate on which the insulating film is formed; and the extension portion is formed so that a cross section of the extension portion, which is orthogonal to a thickness direction thereof, is symmetric with respect to a line passing a center of the sealing member in a width direction thereof, and further, a width of the extension portion in the width direction of the sealing member is formed smaller than a width of the sealing member obtained after adhering the pair of substrates to each other.
