Abstract:
A method for fabricating a liquid crystal display comprising the steps of:forming a shielding layer on a substrate;forming a buffer layer on said substrate and said shielding layer, the substrate having a pixel region and a driver circuit region;forming a plurality of polycrystalline semiconductor layers on the buffer layer on the pixel region and the driver circuit region;forming first impurity regions in one of the plurality of semiconductor layers in the pixel region and in a first one of the plurality of semiconductor layers on the driver circuit region;forming a gate insulating layer on the substrate;forming a gate electrode and a gate bus line;forming a second impurity region in said one of the plurality of semiconductor layers in the pixel region;forming a third impurity region in a second one of the plurality of semiconductor layers on the driver circuit region;forming an insulating layer over said pixel and driver circuit regions, said insulating layer having a contact hole over a portion of the pixel region; andforming a transparent electrode over the pixel region and into the contact hole so as to form a source/drain electrode and a data bus line.
