Abstract:
A liquid crystal display has (i) first and second substrates having electrodes and a pretilt angle of 88.5° to 89.5°, (ii) a liquid crystal layer, having a thickness d and made of liquid crystal molecule material which has a twist structure at a twist angle of 160° to 240° in a voltage application state, the liquid crystal layer containing chiral material having a pitch of p, where d/p is 0.2 to 0.74, (iii) a first polarizer disposed facing the first substrate, the first polarizer having as a transmission axis direction a first direction, (iv) a second polarizer disposed facing the second substrate, the second polarizer having as a transmission axis direction a second direction having an angle of 85° to 95° relative to the first direction, and (v) an optical anisotropic plate disposed at least one of between the first substrate and first polarizer and between the second substrate and second polarizer.
