Abstract
A method for fabricating a color-filter on transistor (COT) type LCD device, to improve the yield by simplifying the fabrication process with diffraction exposure, which includes the steps of forming a gate line, a gate electrode, a gate pad and a data pad on a substrate; depositing a gate insulating layer and an active layer; forming a data line intersecting the gate line to define a unit pixel region, source and drain electrode on the active layer, and first and second connection conductive layers forming an insulating interlayer on the remaining portions except the first and second connection conductive layers and the drain electrode; forming a color filter layer and a black matrix layer on the insulating interlayer; forming an overcoat layer on the remaining portions of the color filter layer except the first and second connection conductive layers and the drain electrode.
