A method for manufacturing an LCD device having gate and data lines includes forming an active layer on an insulating substrate; forming a gate insulating layer over a surface of the insulating substrate including the active layer; forming a gate line and a gate electrode on the gate insulating layer, so that the gate electrode is positioned above the active layer; forming a photoresist pattern on the gate electrode and on the gate line where the gate and the data lines cross each other, wherein, the photoresist pattern surrounds the gate electrode and the gate line; forming source and drain regions in the active layer by injecting impurity ions into the active layer using the photoresist pattern as a mask; removing the photoresist pattern; forming an insulating interlayer over the entire surface of the insulating substrate, the insulating interlayer having first contact holes exposing predetermined portions of the source and drain regions; forming a data line electrically connected to the source region and crossing over the gate line on the insulating interlayer; forming a drain electrode; forming a passivation layer over the surface of the insulating substrate, the passivation layer having a second contact hole exposing a predetermined portion of the drain electrode; and forming a pixel electrode to electrically connect to the drain region through the second contact hole.
