This invention relates to a liquid crystal display device that reduces a parasitic capacitance, and a fabricating method thereof.A liquid crystal display device, including: a gate line with a multi-layer structure having a transparent first conductive layer and an opaque second conductive layer; a data line crossing the gate line with a gate insulating film in between to define a pixel area; a thin film transistor connected to the gate line and the data line; a pixel electrode formed of the first conductive layer in the pixel area, wherein the second conductive layer remains along an edge of the first conductive layer at an edge of the pixel area; a transmission hole that penetrates from an organic insulating film on the thin film transistor to the gate insulating film to expose the first conductive layer of the pixel electrode; a reflection electrode on the organic insulating film extending along a part of a side surface of the transmission hole to connect the pixel electrode and a drain electrode of the thin film transistor; and a floating electrode on the organic insulating film that overlaps both sides of the data line.
