Abstract:
1. A liquid crystal display (LCD) device comprising: a first substrate having a TFT array; a second substrate having a color filter array opposing to the first substrate; a first column spacer on the second substrate, the first column spacer comprising a first pattern having a first cross-section and a first height and a second pattern having a second cross-section and a second height smaller than that of the first pattern, the first and second patterns being directly connected to each other; a second column spacer on the second substrate to have a height corresponding to the first height of the first pattern of the first column spacer; and a liquid crystal layer between the first and second substrates, wherein the second pattern is arranged in a center portion of the first pattern and in contact with the first substrate, wherein the first pattern and the second pattern are formed of a same material in a single layer structure and, wherein the first pattern has a first cross-section of about 10 μm˜35 μm×10 μm˜35 μm, and the second pattern has a second cross-section of about 0.1 μm˜10 μm×0.1 μm˜10 μm.
