Abstract
In a liquid crystal displaying device where the aperture ratio is made higher by using a photocuring adhesive sealant for adhering two substrates, and the contraction of tact time is achieved, a liquid crystal displaying device which is free from inferior curing of the adhesive sealant and is high in reliability can be obtained. In two substrates for forming a liquid crystal displaying device, where the substrates have at least one layer of light shielding film, the inferior curing of the photocuring adhesive sealant can be removed by limiting the width of the light shielding film existing above or under the adhesive sealant which glues the two substrates. As this result, a liquid crystal displaying device which is high in aperture ratio and high in reliability can be obtained.
