Abstract:
1. A multi-domain liquid crystal display (LCD) device, comprising: a plurality of gate and data lines perpendicular to each other on a first substrate defining a plurality of pixel regions, each of the pixel regions divided into at least first and second domains, wherein the first and second domains are symmetric with respect to a virtual line which divides the pixel region into the first and second domains; a plurality of thin film transistors each at a crossing portion of the gate and data lines; an insulating layer within each of the pixel regions and having a plurality of first protrusions arranged along different directions in each of the first and second domains of the pixel regions, wherein each of the protrusions is formed as an elliptical shape having major-axes and minor-axes, and the major-axes of the protrusions within the first domain are disposed along a direction vertical to a direction of the major-axes of the protrusions within the second domain; a plurality of pixel electrodes on the insulating layer, each pixel electrode having a plurality of second protrusions corresponding to the first protrusions of the insulating layer; a second substrate having a black matrix layer and a color filter layer; and a liquid crystal layer between the first and second substrates.
