Patent ID: 6970215

Claim:
A transflective liquid crystal device comprising: a first transparent substrate; a second transparent substrate opposed to the first substrate; a liquid crystal held between the first and second substrates; a light source provided on a side of the first substrate, which is opposite to the liquid crystal side thereof; a transflective 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 Î”nd (product of optical anisotropy An and thickness d) of the liquid crystal are 0.85 Î¼m or less and 0.70 Î¼m or more, respectively; Î”nd of the first retardation plate is 150Â±50 nm or 600Â±50 m; Î”nd of the second retardation plate is 550Â±50 nm; an angle Î¸ 1 formed by a transmission axis or absorption axis of the polarizer and an optical axis of the second retardation plate is 15 to 35 degrees; and an angle Î¸ 2 formed by an optical axis of the first retardation plate and the optical axis of the second retardation plate is 60 to 80 degrees.
