A touch sensing type liquid crystal display device includes an array substrate includes an array substrate including a first substrate, a common electrode, a pixel electrode, and a touch sensing unit; a color filter substrate including a second substrate and facing the array substrate; an anti-static layer on an outer side of the second substrate and including an inorganic material and conductive particles; and a liquid crystal layer between the first substrate and an inner side of the second substrate.

Touch sensing type liquid crystal display device including anti-static outer layer and method of fabricating the same

A method of manufacturing an array substrate for a fringe field switching mode liquid crystal display includes: forming an auxiliary insulating layer on a second passivation layer and having a first thickness; forming first and second photoresist patterns on the auxiliary insulating layer and having second and third thicknesses, respectively, the second thickness greater than the third thickness; etching the auxiliary insulating layer, the second passivation layer and a first passivation layer to form a drain contact hole; performing an ashing to remove the second photoresist pattern and expose the auxiliary insulating layer therebelow; performing a dry etching to remove the auxiliary insulating layer not covered by the first photoresist pattern and expose the first passivation layer and to form an insulating pattern below the first photoresist pattern, the insulating pattern and the first photoresist pattern forming an undercut shape; forming a transparent conductive material layer having a fourth thickness less than the first thickness; and performing a lift-off process to remove the first photoresist pattern and the transparent conductive material layer thereon together and form a pixel electrode as a remaining portion of the transparent conductive material layer.
