Abstract:
1. A transflective liquid crystal display (LCD) device comprising first and second polarizing films having polarizing axes perpendicular to one another, a liquid crystal (LC) layer interposed between said first polarizing film and said second polarizing film, said LC layer defining an array of pixels each including a reflective region and a transmissive region juxtaposed, wherein: LC molecules of said LC layer have a longer axis extending parallel to or normal to the polarization direction of the light incident onto said LC layer in said reflective region; and each of said pixels includes a pixel electrode receiving a pixel signal which is common between said reflective region and said transmissive region, a first common electrode, formed in said reflective region, receiving a first common signal which is common among said reflective regions of a plurality of said pixels, and a second common electrode, formed in said transmissive region, receiving a second common signal which is common among said transmissive regions of said plurality of said pixels, wherein said pixel electrode includes a first pixel electrode formed in said reflective region and a second pixel electrode formed in said transmissive region, and each of said pixels is associated with a first switching device for coupling a data line to said first pixel electrode, and a second switching device for coupling said data line to said second pixel electrode, and wherein said reflective region includes therein a reflection film having a potential substantially equal to a median between a potential of said first pixel electrode and a potential of said first common electrode.
