Abstract: An array substrate for an in-cell type touch sensor liquid crystal display device includes: a substrate; a gate line and a data line on the substrate; a thin film transistor connected to the gate line and the data line; a first passivation layer on the thin film transistor; a common electrode on the first passivation layer; an etching preventing pattern covering the drain contact hole; an x sensing line and a y sensing line on the common electrode; a second passivation layer on the x sensing line and the y sensing line; and a pixel electrode on the second passivation layer.
