Abstract
According to one embodiment, a liquid crystal display device includes a first substrate including a first alignment film covering a pixel electrode, a second substrate including a second alignment film covering a second common electrode, a sealant attaching the first substrate and the second substrate, and a liquid crystal layer held between the first alignment film and the second alignment film, wherein the first alignment film and the second alignment film are formed of a material in which a principal chain is composed of silica (SiO2), and extend at a position overlapping the sealant between an inner face and an outer face of the sealant.

A liquid crystal display device comprising:
- a first substrate including a first insulative substrate, a switching element located above the first insulative substrate, a first interlayer insulation film covering the switching element, a first common electrode formed on the first interlayer insulation film, a second interlayer insulation film covering the first common electrode, a pixel electrode formed on the second interlayer insulation film and electrically connected to the switching element, and a first alignment film covering the pixel electrode;
- a second substrate including a second insulative substrate, a second common electrode extending on that side of the second insulative substrate, which is opposed to the first substrate, and having the same potential as the first common electrode, and a second alignment film covering the second common electrode;
- a sealant attaching the first substrate and the second substrate in a state in which a cell gap is created between the first substrate and the second substrate;
- and
- a liquid crystal layer including liquid crystal molecules held between the first alignment film and the second alignment film,
- wherein the first alignment film and the second alignment film are formed of a material in which a principal chain is composed of silica (SiO2), and extend at a position overlapping the sealant between an inner face and an outer face of the sealant.
A liquid crystal display device comprising:
