Abstract
An in-cell touch liquid crystal display device and a method for manufacturing the same are disclosed in which color mixing among pixels can be prevented. The in-cell touch liquid crystal display device includes a thin film transistor (TFT) arranged in a plurality of pixel areas; a source contact layer connected to a source electrode of the TFT and a drain contact layer connected to a drain electrode of the TFT; first and second passivation layers on the source contact layer and the drain contact layer; a common electrode on the second passivation layer; a third passivation layer on the common electrode; a conductive line to overlap the common electrode by passing through the third passivation layer; a fourth passivation layer on the third passivation layer and the conductive line; and a pixel electrode on the fourth passivation layer connected to the drain contact layer in a first contact hole.
