Patent ID: 7864274

Claim:
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 only to said transmissive area; and a retardation film sandwiched between said first polarizing film and said LC layer, wherein each of said pixels includes a pixel electrode driven by a pixel data signal supplied in common to said transmissive area and said reflective area, a first common electrode driven by a first common signal supplied in common to said reflective areas of said plurality of pixels, and a second common electrode driven by a second common signal supplied in common to said transmissive areas of said plurality of pixels, wherein said first and second common signals are inverted in synchrony with a synchronizing signal, and said first common signal is substantially an inverted signal of said second common signal.
