A display device is provided, in which a member for sealing a liquid crystal is formed at sides of a pair of opposing substrates, so that a space other than an effective display region is made small and a substrate size is reduced. The pair of substrates is bonded to each other with a predetermined gap provided therebetween by an adhesive layer, and a liquid crystal injected in the gap is sealed in. The adhesive layer is formed closely to the sides of the substrates, so that a space where a sealing material is conventionally formed becomes unnecessary and the substrate size is made small. Moreover, a tape close to the adhesive layer is fixed to the sides of the substrates, so that an outer peripheral portion of the substrates is protected against impact, contamination, and electrostatic breakdown, and handling is simplified.
