ABSTRACT:
A liquid crystal display device having a multilayer structure includes at least one substrate, first electrodes arranged on the substrate into a predetermined pattern for constituting a plurality of pixels and second electrodes arranged across from the first electrode by a predetermined interval therebetween, liquid crystal layers filling the gap between the electrodes, at least one insulation layer arranged between the liquid crystal layers for separating the liquid crystal layers into a multiple lamination structure, columns having protrusions extending radially and outwardly between the upper and lower insulation layers at each vertical level of outer walls for securing the insulation layer within the liquid crystal layer, and protective insulation layers for protecting the first and second electrodes. Therefore, contact strength between columns and insulation layers can be significantly enforced so that the columns and insulation layers can avoid becoming separated from each other, and insulation layers can be stably maintained.
