A new, highly multiplexable liquid crystal display is described, which has a superior image quality than a twisted nematic display multiplexed at the same high level. The display cell consists of a chiral‐doped nematic layer with tilted boundaries and a twist angle of ∼270°. It operates in a birefringent optical mode between two ‘‘nonconventionally’’ oriented polarizers. Performance characteristics presented for a 120×240 dot matrix panel multiplexed at a 1/120 duty cycle include driving voltages compatible with complementary‐metal‐oxide‐semiconductor technology, 300‐ms response times, a contrast ratio of 10:1 at normal incidence, and ≥4:1 inside a viewing cone of 45° from the vertical.
