Abstract

There is provided a liquid crystal device having high reliability, a method of manufacturing a liquid crystal device, and an electronic apparatus. A liquid crystal device includes a seal material for sticking an element substrate and a counter substrate together, an encapsulant for filling an opening region in which the seal material is opened, a liquid crystal layer interposed by the element substrate and the counter substrate, a first inorganic alignment film provided between the element substrate and the liquid crystal layer, and a second inorganic alignment film provided between the counter substrate and the liquid crystal layer, in which at least the first inorganic alignment film is expanded and arranged in a region overlapping with the encapsulant in plan view.

First claim

The invention claimed is:

1. A liquid crystal device comprising:
a first substrate;
a second substrate arranged facing the first substrate;
a seal material arranged between the first substrate and the second substrate;
a liquid crystal layer arranged between the first substrate and the second substrate;
an encapsulant filling the liquid crystal layer in an opening region of the seal material;
a first inorganic alignment film arranged between the first substrate and the liquid crystal layer;
an organic surface layer arranged on the first inorganic alignment film between the first inorganic alignment film and the encapsulant; and
a second inorganic alignment film arranged between the second substrate and the liquid crystal layer,
wherein the first inorganic alignment film and the organic surface layer are disposed so as to overlap entirely the encapsulant, when viewed from the second substrate side.

2. The liquid crystal device according to claim 1 , wherein the first inorganic alignment film is arranged so as to overlap with at least a part of a region in which the seal material is arranged when being viewed from the second substrate side.

3. The liquid crystal device according to claim 1 , wherein the first inorganic alignment film and the organic surface layer are arranged so as to overlap only a part of a region in which the seal material is arranged when viewed from the second substrate side.

4. The liquid crystal device according to claim 1 , wherein the first inorganic film and the organic surface layer overlap from approximately one-third (⅓) to approximately one-half (½) of a width of the seal material.

5. A liquid crystal device comprising:
a first substrate;
a first inorganic alignment film arranged between the first substrate and a liquid crystal layer; and
an organic surface layer arranged on the first inorganic alignment film between the first inorganic alignment film and the liquid crystal layer;
wherein the first inorganic alignment film and the organic surface layer are disposed so as to overlap entirely an encapsulant, which fills the liquid crystal layer in an opening region of a seal material, when viewed from the liquid crystal layer side.

6. The liquid crystal device according to claim 5 , wherein the first inorganic alignment film is arranged so as to overlap with at least a part of a region in which the seal material is arranged when being viewed from the liquid crystal layer side.

7. A method of manufacturing a liquid crystal device comprising:
an inorganic alignment film forming step of forming a first inorganic alignment film on a first substrate;
a surface layer forming step in which an organic surface layer is formed on the first inorganic alignment film;
a seal material forming step of forming a seal material on the first substrate;
a sticking step of sticking the first substrate and a second substrate on which a second inorganic alignment film is formed together through the seal material;
an injecting step of injecting a liquid crystal between the first substrate and the second substrate from an opening region of the seal material; and
an encapsulant forming step of forming an encapsulant filling the liquid crystal in the opening region,
wherein the first inorganic alignment film and the organic surface layer are disposed so as to overlap entirely the encapsulant, when viewed from the second substrate side.

8. An electronic apparatus comprising the liquid crystal device according to claim 1 .

9. An electronic apparatus comprising the liquid crystal device according to claim 5 .
