Abstract:
A method of manufacturing a liquid crystal display having high aperture ratio and high transmittance comprising the steps of:forming a gate bus line and a common signal line on a lower substrate;forming a gate insulating layer on the lower substrate in which the gate bus line and the common signal line are formed;forming a channel layer on a selected portion of the gate insulating layer comprising the gate bus line;forming a source and a drain electrodes so as to overlap with both sides of the channel layer, and a data bus line being arranged perpendicular to the gate bus line;etching the gate insulating layer so as to expose a selected portion of the common signal line;forming a counter electrode by depositing an ITO layer on the gate insulating layer, and by patterning a selected portion thereof so as to contact with the exposed common signal line;depositing a passivation layer over the gate insulating layer in which the counter electrode is formed;etching the passivation layer so as to expose a selected portion of the drain electrode; andforming a pixel electrode, by depositing the ITO layer on the passivation layer so as to contact to the exposed drain electrode, and by patterning a selected portion of the ITO layer so that a fringe field is formed by being overlapped with the counter electrode.
