Abstract: Disclosed is a touch sensitive display apparatus which decreases a load of each of a plurality of touch electrodes and reduces a load deviation between the plurality of touch electrodes, thereby enhancing image quality. The touch sensitive display apparatus comprises a touch sensitive panel. The touch panel comprises a plurality of touch electrodes comprising at least a first touch electrode. The first touch electrode comprises a plurality of first touch electrode lines that are parallel to each other. A first touch signal line is connected to the plurality of first touch electrode lines of the first touch electrode, and the first touch electrode is driven for image display and touch sensing via the first touch signal line. A first connecting line is in a different layer than the first touch electrode lines, and the first connecting line is connected to the plurality of first touch electrode lines.

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.
