Patent Images
1. A transflective liquid-crystal-display (LCD) device comprising:
- a liquid crystal (LC) layer defining a plurality of pixels each having a transmissive area and a reflective area, at least said transmissive area operating in a lateral-electric-field mode;
first and second polarizing films sandwiching therebetween said LC layer, said first polarizing film being effective common to said transmissive area and said reflective area, said second polarizing film being effective to said transmissive area; and
a retardation film sandwiched between said first polarizing film and said LC layer.

Abstract
A LCD device has a LC layer sandwiched between a TFT substrate and a counter substrate, first and second polarizing films, a first λ/2 film between the first polarizing film and the counter substrate, and a second λ/2 film between the second polarizing film and the TFT substrate. Angle θ1 between the direction of the optical axis of the LC layer and the polarized direction of the light entering the LC layer satisfies the relationship: 0 degree<θ1<45 degrees. The resultant LCD device has lower leakage light and coloring.
