1. A liquid crystal display (LCD) device, comprising:

  • a first substrate having a plurality of pixels;

    a second substrate facing the first substrate;

    a liquid crystal layer interposed between the first and second substrates;

    a main spacer disposed between the first and second substrates and making contact with the first and second substrates, and the main spacer having a first top surface and a first bottom surface having an area larger than that of the first top surface; and

    a supplementary spacer disposed between the first and second substrates to make contact with one of the first and second substrates and be spaced apart from the other, and the supplementary spacer having a second top surface and a second bottom surface having an area larger than that of the second top surface,and the supplementary spacer being harder than the main spacer,wherein a first area ratio, which is defined by dividing the area of the first top surface by that of the first bottom surface, is smaller than a second area ratio, which is defined by dividing the area of the second top surface by that of the second bottom surface.
