Abstract
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. Between a pixel area and the seal material, a first groove is formed along a sidefrom the cornertoward a corner. 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 cornerside, 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 sidetoward the side of a sideoccurs in the pixel area, and thus the liquid crystal can be smoothly circulated.
