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. 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.
