Abstract:
1. 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 Δnd (product of optical anisotropy An 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 or 600±50 m; Δnd of the second retardation plate is 550±50 nm; an angle θ an angle θ
