Patent ID: 7379133

Claim:
A reflective liquid crystal device comprising: a first substrate; a transparent second substrate opposed to the first substrate; a liquid crystal held between the first and second substrates; a reflecting electrode layer arranged on the first substrate opposite to the second substrate; a polarizer provided on a side of the second substrate, which is opposite to a first substrate side thereof; a first retardation plate arranged between the polarizer and the second substrate; and a second retardation plate arranged between the polarizer and the first retardation plate; wherein a twist angle of the liquid crystal is 230 to 260 degrees; a minimum and maximum Δnd (product of optical anisotropy Δn and thickness d) of the liquid crystal are 0.85 μm or less and 0.70 μm or more, respectively; Δnd of the first retardation plate is 150±50 nm; Δnd of the second retardation plate is 610±60 nm; an angle θ 1 formed by a transmission axis or absorption axis of the polarizer and an optical axis of the second retardation plate is 10 to 35 degrees; and an angle θ 2 formed by an optical axis of the first retardation plate and the optical axis of the second retardation plate is 30 to 60 degrees.
