ABSTRACT:
A liquid crystal display device comprises a liquid crystal layer containing a nematic liquid crystal material, first and second light-transmissive substrates which hold the nematic liquid crystal material therebetween such that liquid crystal molecules are aligned in a predetermined directions, and first and second circular electrodes which are formed on the first and second light-transmissive substrates and apply to the liquid crystal layer an electric field for controlling the orientation of the liquid crystal molecules. In particular, the first and second circular electrodes include radial light-shielding electrode lines and concentric light-shielding electrode lines, which are opposed to each other to divide the liquid crystal layer into a plurality of domains between which liquid crystal molecules are set in different tilt directions under the electric field.
