Abstract
Disclosed are an in-cell touch liquid crystal display (LCD) device based on a twisted nematic (TN) mode, a method of manufacturing the same, a method of manufacturing a thin film transistor (TFT) array substrate, and a method of manufacturing a color filter array substrate. The TFT array substrate includes a TFT disposed in a pixel area defined by an intersecting gate line and data line, a conductive line disposed on the TFT, and a transparent conductive layer in electrical contact with the conductive line. The color filter array substrate includes a light shield layer, a color filter, an overcoat layer covering the light shield layer and the color filter, a column spacer disposed on the overcoat layer, and a common electrode disposed on the overcoat layer and the column spacer, where the conductive line supplies the common electrode with a common voltage or a touch driving signal.
