Abstract: A liquid crystal display which can decrease parasitic capacitance developing at the crossing points of gate bus lines and data bus lines and can improve step coverage of a data bus line at the crossing point, comprising an insulating transparent substrate, a plurality of islandic conductive layers formed at the crossing points of the gate; lines and data lines on the insulating transparent substrate, a plurality of the gate lines formed on the substrate connecting opposing edges in one direction of each conductive layer, and a plurality of the data lines crossing above the conductive layers perpendicular to each gate line, isolated from conduction materials and gate lines.

Abstract: The method comprising the steps of: depositing a semiconductor layer serving as an active layer, a first gate insulation film and an second gate insulation film on an insulation-transparent substrate, in this order; patterning the second gate insulation film using a mask for the patterning of an active region so that it is remained merely at the active region; oxidizing the semiconductor layer except for the active region using the patterned second gate insulation film as an oxidization mask, to isolate the active region from the other portion; forming a gate electrode on the second gate insulation film corresponding to the upper side of the defined active region; implanting impurity-ions in the semiconductor layer using the gate electrode as an ion-implantation mask to form a source region and a drain region; forming a protection film on the whole exposed surface of the resultant structure; forming contact holes in the protection layer so that the source region and the drain region are exposed; and forming a
