Abstract

The present multi-domain liquid crystal display device includes first and second substrates facing each other, a liquid crystal layer between the first and second substrates, a plurality of gate bus lines arranged in a first direction on the first substrate and a plurality of data bus lines arranged in a second direction on the first substrate to define a pixel region, a thin film transistor positioned at a crossing area of the data bus line and the gate bus line and comprising a gate electrode, a semiconductor layer, and source/drain electrodes, a pixel electrode in the pixel region, a light shielding layer on the second substrate, a color filter layer having electric field-distorting recesses on its surface on the light shielding layer, a common electrode having recesses corresponding to the electric field-distorting recesses of the color filter layer, and an alignment layer on at least one substrate between the first and second substrates.
