Embodiments of the present disclosure are related to a touch display device, as implementing a portion of a touch link line by using a metal disposed on a layer different from a layer where a data link line is disposed and disposing a color filter layer between the touch link line and the data link line, a plurality of link lines can be disposed effectively and a parasitic capacitance between the touch link line and the data link line can be reduced. Furthermore, as blocking a light of specific wavelength band by the color filter layer, a light-leakage due to an abnormal driving of a display according to a driving of the touch link line on an area where the touch link line is disposed can be prevented or at least reduced.

Touch display device with color filter between data link lines and touch link lines

A touch display device drives only some of a plurality of common electrodes disposed in a display panel as a touch electrode, so that an increase of lines and a reduction of an aperture ratio according to implementing a function of a touch sensing can be minimized, and as adjusting a total resistance and a resistance distribution according to locations between the common electrode driven as the touch electrode and the common electrode not driven as the touch electrode same or similarly, an abnormality of a display driving due to partial driving the plurality of common electrodes as the touch electrode and provide the function of the touch sensing can be prevented.

Touch display device

An array substrate having a wiring of a pad region formed without an insulating film or without an insulating film and an organic film to reduce abnormal operations due to an increase in resistance caused by a contact margin at a high temperature, and a method for manufacturing the same are provided. The array substrate includes: an insulating substrate including a pad region and a thin film transistor (TFT) formation region; a first electrode layer formed in the pad region of the substrate; and a second electrode formed on the first electrode layer in an overlapping manner.
