ABSTRACT:
An LCD device (2) includes two substrates (21, 22), a liquid crystal layer (27) therebetween, and gate lines (24) and data lines (23) formed on one substrate thereby defining pixel regions. A set of pixel electrodes (26) and a set of common electrodes (25) are provided in each pixel region. A first subset of the pixel electrodes and a first subset of the common electrodes are disposed parallel to each other in alternating fashion and extend along a first horizontal axis, a second subset of the pixel electrodes and a second subset of the common electrodes are disposed parallel to each other in alternating fashion and extend along a second horizontal axis, and the first and second axes are inclined at respective angles relative to the data lines. Thus when voltage is applied, liquid crystal molecules are twisted in two different directions (281, 282) so as to reduce color shift.
