Abstract:
A liquid crystal device includes an OCB mode liquid crystal panel including a pair of substrates and a liquid crystal layer disposed therebetween, an optical compensator provided on at least one side of the liquid crystal panel, and an optical-axis-adjusting unit that moves the optical compensator relative to the liquid crystal panel to adjust an angle formed by an optical axis of the optical compensator and an optical axis of the liquid crystal panel.
