Abstract
Bubbles mixed in liquid crystal injected into a liquid crystal cell are pushed out through an outlet. The outlet has a space secured to a maximum limit by an extended sealing portion reaching the outer peripheral end surfaces of substrates, and a step with a color filter is formed. The pushed-out bubbles are surely trapped by the space of the outlet. In a replenishing port for replenishing liquid crystal, an introduction spacer having a height equal to that of the color filter is provided, and by a capillary phenomenon, liquid crystal for replenishment can be smoothly introduced into the liquid crystal cell.
