A liquid crystal display device includes a substrate; a gate line and a data line positioned on the substrate; a thin film transistor connected to the gate line and the data line; a passivation layer positioned on the gate line, the data line, and the thin film transistor; a first electrode positioned on the passivation layer; an interlayer insulating layer positioned on the first electrode; and a second electrode positioned on the interlayer insulating layer, wherein the first electrode includes a first layer made of an indium-zinc oxide in which a weight ratio of an indium oxide is 20 wt % or less or made of a transparent metal oxide that does not contain an indium oxide.
