In a liquid crystal apparatus, a liquid crystal is provided in a cavity surrounded by a seal material between a first substrate and a second substrate, and the liquid crystal is aligned in a diagonal direction formed by corners 10a1, 10a3. Between a pixel area and the seal material, a first groove is formed along a side 20a6 from the corner 10a1 toward a corner 10a2. When a first pump is driven, the liquid crystal of the pixel area is drawn from a first end of the first groove on the corner 10a1 side, and the liquid crystal is ejected from a second end into the pixel area. As a result, a liquid crystal flow from the side of a side 20a7 toward the side of a side 20a9 occurs in the pixel area, and thus the liquid crystal can be smoothly circulated.

A liquid crystal device includes: an element substrate; a counter substrate disposed opposite to the element substrate; a sealing material disposed between the element substrate and the counter substrate; and a liquid crystal layer disposed on an inner side of the sealing material and containing liquid crystal. The element substrate includes an alignment film configured to align the liquid crystal and an ion-adsorbing first adsorption film disposed in contact with the sealing material. The alignment film includes a first vapor-deposited film and a second vapor-deposited film disposed between the first vapor-deposited film and the liquid crystal layer. The second vapor-deposited film and the first adsorption film include a column of which a long axis direction intersects a thickness direction of the liquid crystal layer. A thickness of the first adsorption film is thicker than a thickness of the second vapor-deposited film.

Included are a first orientation region in which a liquid crystal molecule is oriented along a first direction and a plurality of pixels are included; a second orientation region in which a liquid crystal molecule is oriented along a second direction intersecting the first direction and a plurality of pixels are included; a third orientation region in which a liquid crystal molecule is oriented along a third direction intersecting the second direction and opposite to the first direction and a plurality of pixels are included; and a fourth orientation region in which a liquid crystal molecule is oriented along a fourth direction intersecting the third direction and opposite to the second direction and a plurality of pixels are included.

In a liquid crystal device, an intermediate refractive index film including a silicon nitride film, a silicon oxynitride film, or an aluminum oxide film is provided between an oriented film formed of a diagonally vapor-deposited film of silicon oxide and an electrode containing ITO. Thus, because there are no interfaces having a large refractive index difference between the oriented film and the electrode, reflection between the oriented film and the electrode can be suppressed. A high density silicon oxide film is formed between the intermediate refractive index film and the oriented film. The high density silicon oxide film is formed by an atomic deposition method, thus is appropriately formed inside a contact hole.

A liquid crystal display apparatus according to the present disclosure includes a first substrate, a second substrate, and a liquid crystal layer. A pixel electrode and a first orientation film are formed on the first substrate. A common electrode and a second orientation film are formed on the second substrate. The liquid crystal layer is disposed between the first orientation film and the second orientation film. The liquid crystal layer within a display area contains a protrusion that does not contribute to formation of a cell gap. The protrusion is formed by a same inorganic material as for an underlying film. An electronic equipment according to the present disclosure includes the liquid crystal display apparatus having the above-described configuration.

A display panel and a display apparatus are provided. The display panel includes a first substrate and a second substrate which are arranged oppositely. A liquid crystal layer is filled between the first substrate and the second substrate, the liquid crystal layer has dielectric anisotropy of parameter in a range from −1 F/m to 1 F/m, a sum of a bending flexural coefficient and a splaying flexoelectric coefficient of the liquid crystal layer is greater than 1 pc/m, and liquid crystal molecules in the liquid crystal layer are deflected by a flexoelectric effect, so that deflecting speed of the liquid crystal molecules in the liquid crystal layer is improved and the response time of the liquid crystal layer is shortened.

Included are a first orientation region in which a liquid crystal molecule is oriented along a first direction and a plurality of pixels are included; a second orientation region in which a liquid crystal molecule is oriented along a second direction intersecting the first direction and a plurality of pixels are included; a third orientation region in which a liquid crystal molecule is oriented along a third direction intersecting the second direction and opposite to the first direction and a plurality of pixels are included; and a fourth orientation region in which a liquid crystal molecule is oriented along a fourth direction intersecting the third direction and opposite to the second direction and a plurality of pixels are included.

In a liquid crystal apparatus, a liquid crystal is provided in a cavity surrounded by a seal material between a first substrate and a second substrate. Between a display area on an inner side of the seal material and the seal material, a circulation flow path coupled to the display area is constituted by the seal material and a partition. The partition is formed simultaneously with the seal material. The circulation flow path is provided with a forced circulation apparatus configured to forcibly cause the liquid crystal of the circulation flow path to flow. The circulation flow path has a higher adsorptivity for ions than the display area, and ionic impurities contained in the liquid crystal passing through the circulation flow path are removed from the liquid crystal in the circulation flow path.
