Abstract: Provided is an LCD device including a first substrate, a second substrate, a liquid crystal layer, a main spacer, and a supplementary spacer. The liquid crystal layer is interposed between the first and second substrates. The main spacer makes contact with the first and second substrates. The supplementary spacer makes contact with one of the first and second substrates and is spaced apart from the other. A first area ratio defined by dividing the area of a first top surface by that of a first bottom surface of the main spacer may be smaller than a second area ratio defined by dividing the area of a second top surface by that of a second bottom surface of the supplementary spacer.
