US 2018/0004056 A1 · In-Cell Touch Liquid Crystal Display Apparatus, Method of Manufacturing the Same, Method of Manufacturing Thin Film Transistor Array Substrate, and Method of Manufacturing Color Filter Array Substrate

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.
