Abstract:
An in-plane switching scheme liquid crystal display (IPS-LCD) unit comprisingfirst and second transparent substrates, a liquid crystal (LC) layer sandwiched therebetween to define a plurality of pixel areas, said LC layer including LC molecules having a substantially uniform initial orientation in a first direction, a pixel electrode and a common electrode disposed for each of said pixel areas for rotating said LC molecules, each of said pixel electrode and said common electrode having a lattice structure including a plurality of first stripes extending substantially parallel to said first direction and a plurality of second stripes extending substantially perpendicular to said first direction, to define a plurality of zones in each of said pixel areas by one of said first stripes of said pixel electrode, one of said second stripes of said pixel electrode and one of said second stripes of said common electrode, wherein a ratio of a gap between said second stripe of said pixel electrode and said second stripe of said common electrode to a gap between said first stripe of said pixel electrode and said first stripe of said common electrode resides between 1.5:1 and 4:1.
