Abstract
A transflective liquid crystal display (70) comprises a liquid crystal cell (38) disposed between a front substrate (40) and a rear substrate (36), a front polarizer (46) located in front of the front substrate (40) and a rear polarizer (32) located behind the rear substrate (36), a front retarder (42, 44) located between the front substrate (40) and the front polarizer (46), a rear retarder (62, 64) located between the rear substrate (36) and the rear polarizer (32), and a light source (30) located behind the rear polarizer (32). A transflective display having a number of differently colored sequentially flashing backlights is also provided.
