Abstract:
1. A liquid crystal display device, comprising: a first substrate, a second substrate, and a third substrate arranged parallel to one another, the first substrate being interposed between the second and third substrates; a first liquid crystal layer interposed between the first substrate and the second substrate, the first liquid crystal layer comprising liquid crystal molecules; a second liquid crystal layer interposed between the first substrate and the third substrate, the second liquid crystal layer comprising liquid crystal molecules; a plurality of thin film transistors and a plurality of first pixel electrodes alternatively arranged at a surface of the first substrate, each of the thin film transistors being electrically connected to a corresponding first pixel electrode; and a plurality of second pixel electrodes arranged at another surface of the first substrate, each of the second pixel electrodes being opposite to one of the first pixel electrodes; wherein between each of the first pixel electrodes and a corresponding second pixel electrode, a contact hole is formed through the first substrate, the first pixel electrode is electrically connected to the corresponding second pixel electrode via the corresponding contact hole, and optical rotations of the liquid crystal molecules of the first liquid crystal layer and the liquid crystal molecules of the second liquid crystal layer are reversed relative to each other, with the liquid crystal molecules of the first and second liquid crystal layers being arranged enantiomorphously at the respective opposite sides of the first substrate.
