ABSTRACT:
A multi-domain liquid crystal display device includes: first and second substrates; a plurality of gate lines on the first substrate in a first direction; a plurality of data lines formed in a second direction to cross the first direction; a plurality of thin film transistors formed in a portion where the gate lines cross the data lines; a plurality of pixel regions between neighboring gate and data lines; a common auxiliary electrode around each pixel region; a plurality of pixel electrodes formed in each pixel region to connect with the thin film transistor; dielectric structures on the second substrate, the dielectric structures being controlled electric field with the common auxiliary electrode and being divided the pixel region into at least four domains; at least one or more additional structures formed at an end portion of the dielectric structures within the pixel region; an alignment film on at least one of the first substrate and the second substrate; and a liquid crystal layer between the first substrate and the second substrate.
