Abstract: A display device includes: a display panel having a display area with a plurality of pixel areas and a non-display area adjacent the display area, the display panel may include a substrate including at least one thin film transistor in each of the pixel areas and a display element connected to the thin film transistor; lighting circuits in the non-display area on the substrate to check lighting states of the display element; signal wires in the non-display area on the substrate to supply a signal to the lighting circuits; dummy circuits including a plurality of dummy capacitors, each of which include a first dummy capacitor electrode and a second dummy capacitor electrode, wherein the dummy circuits collect external static electricity coming through the signal wires before the external static electricity flows into the lighting circuits.

Abstract: A liquid crystal display device includes a first substrate, a second substrate facing the first substrate, a liquid crystal layer disposed between the first and second substrates, a pixel electrode, a common electrode facing the pixel electrode, a plurality of first touch electrodes, and a plurality of second touch electrodes. Each first touch electrode includes a main body portion extending in a first direction and a plurality of branching portions extending from the main body portion in a second direction. The plurality of second touch electrodes cross the main body portion of each first touch electrode.

Abstract: A display device and manufacturing method thereof are disclosed. In one aspect, the display device includes a substrate including a display area and a peripheral area surrounding the display area, wherein the display area includes a plurality of pixels configured to display images and a plurality of inspection pads formed in the peripheral area and configured to transmit a plurality of inspection signals to the pixels. Each of the inspection pads includes a poly resistor formed over the substrate, at least one insulating layer formed over the poly resistor, first and second conductive wires formed over the insulating layer and respectively connected to opposing ends of the poly resistor, and a protective layer formed over the insulating layer and substantially overlapping the poly resistor.
