A liquid crystal device has inorganic alignment layers (36, 42) disposed on a surface of a liquid crystal layer side of a pair of the substrates, when the range of the average pre-tilt angle θ of liquid crystal molecules 50a of the liquid crystal layer is 5 degrees ≦θ≦20 degrees, twist angle φ of the liquid crystal molecules (50a) of the liquid crystal layer, cell gap d, and helical pitch P of the liquid crystal molecules of the liquid crystal layer satisfy the relationship of (0.6/360)φ<d/P<(1.4/360)φ, and when the range of the average pre-tilt angle θ of liquid crystal molecules 50a of the liquid crystal layer is θ>20 degrees, twist angle φ of the liquid crystal molecules (50a) of the liquid crystal layer, cell gap d, and helical pitch P of the liquid crystal molecules of the liquid crystal layer satisfy the relationship of (0.8/360)φ<d/P<(1.6/360)φ.
A method for manufacturing a substrate used for a liquid crystal device by slant vacuum deposition of an inorganic material on an underlayer having a gap section on a surface formed on the substrate so as to form an inorganic alignment layer, comprising:
