Abstract:
1. A liquid crystal display (LCD) device, comprising: first and second substrates facing each other; a plurality of gate and data lines on the first substrate, the gate and data lines crossing each other at crossing regions to define a plurality of pixel regions; a plurality of thin film transistors each formed at the crossing region of the gate and data lines; a plurality of pixel and a plurality of common electrodes on the same substrate each within one of the pixel regions; a first column spacer on the second substrate corresponding to one of the thin film transistors of the first substrate; a second column spacer on the second substrate corresponding to the gate lines of the first substrate; and a liquid crystal layer between the first and second substrates, wherein a height of the first column spacer decreases within a range of about 2000 Angstroms to about 6000 Angstroms and wherein the second column spacer is spaced apart from the first substrate by a first interval when the first substrate and the second substrate are bonding each other and no external compressive pressure is applied to the first substrate or the second substrate.
