ABSTRACT:
A liquid crystal display device includes a first substrate having a plurality of first electrodes, a second substrate facing the first substrate and having a plurality of second electrodes perpendicular to the first electrodes to define sub-pixels at intersection regions between the first and second electrodes, a liquid crystal layer between the first and second substrates, a plurality of color filters between the first and second substrates adapted to correspond to respective sub-pixels, the color filters including first color filters and second color filters having a different shape than the first color filters, a black matrix between the color filters, the black matrix including vertical portions, horizontal portions, and step portions, each of the step portions corresponding to a respective second color filter, and a plurality of patterned spacers between the first and second substrates, each of the patterned spacers overlaps with a respective step-portion of the black matrix.
