Abstract
According to one embodiment, a liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, a first alignment film, and a sealant, wherein the first alignment film is an optical alignment film, the sealant includes an epoxy resin not having an acrylate skeleton and a resin having an acrylate skeleton, a storage elastic modulus of the sealant is greater than or equal to 1.0×107 Pa and less than or equal to 1.5×109 Pa, and at least a part of the sealant is in contact with the first alignment film.
Claims17
A liquid crystal display device comprising:
- a first insulating substrate;
- a second insulating substrate disposed at a position opposed to the first insulating substrate;
- a liquid crystal layer which is arranged between the first insulating substrate and the second insulating substrate, and includes liquid crystal molecules;
- a first alignment film which is formed on the first insulating substrate, and aligns the liquid crystal molecules;
- an insulating film which is disposed between the first insulating substrate and the first alignment film, and is in contact with the first alignment film;
- a sealant which adheres the first insulating substrate and the second insulating substrate;
- an organic insulating film disposed on the second insulating substrate;
- and
- a plurality of spacers which are made of an acrylic resin, extend from the second insulating substrate to the first insulating substrate, and contact with and penetrate the sealant, wherein
- the first alignment film is an optical alignment film,
- the sealant includes an epoxy resin not having an acrylate skeleton and a resin having an acrylate skeleton,
- a storage elastic modulus of the sealant is greater than or equal to 1.0×107 Pa and less than or equal to 1.5×109 Pa,
- at least a part of the sealant is in contact with the first alignment film, and
- at least a part of the first alignment film is disposed between the sealant and the insulating film.
