Abstract:
1. A method for manufacturing a liquid crystal display device having a first and second substrates comprising: forming a plurality of gate lines and gate electrodes on the first substrate; forming a gate insulation film over the first substrate, including the gate lines and gate electrodes; forming semiconductor layers on the gate insulation film over the gate electrodes, and simultaneously forming first protrusion patterns on the gate insulation film; forming a plurality of data lines on the gate insulation film perpendicular to the gate lines such that the data lines and gate lines define pixel regions, and simultaneously forming source and drain electrodes, and second protrusion patterns on the first protrusion pattern; forming a passivation film over the surface of the gate insulation film, including the data lines, source and drain electrodes, and first and second protrusion patterns; forming contact holes for exposing the drain electrodes to the outside, and recesses around the respective first protrusion patterns on the gate lines via selective removal of the passivation film; forming pixel electrodes contacting drain electrodes via the contact holes; forming a color filter array on the second substrate; forming a plurality of first column spacers on the second substrate at positions corresponding to the respective protrusions, and a plurality of second column spacers on the second substrate at positions of the second substrate corresponding to regions of the gate lines other than where protrusions are formed; and forming a liquid crystal layer between the first and second substrates.
