Abstract
A transflective LCD unit includes an array of pixels each including a reflective area and a transmissive area. The LC layer has an effective retardation of λ/4 in the reflective area, and an effective retardation of λ/2 in the transmissive area. A retardation film disposed in the reflective area provides a retardation of λ/2 to the light passed thereby. An angle of θ between the optical axis of the retardation film and the polarized direction of the light is in a range of 0 degree<θ<22.5 degrees.
