Display device and method of manufacturing the same

摘要

A display device and a method of manufacturing the same are disclosed, in which a sensing electrode for sensing a touch of a user is built in a display panel, whereby a separate touch screen is not required on an upper surface of the display panel unlike the related art and thus thickness and manufacturing cost are reduced.

主权项

1. A display device comprising:
a thin film transistor in a pixel region having a gate line and a data line crossing the gate line, the thin film transistor having a gate electrode, a semiconductor layer, a source electrode, and a drain electrode; a data pad connected with one end of the data line; a first passivation film on the thin film transistor and the data pad; a second passivation film on the first passivation film over the thin film transistor and over the data pad, the first and second passivation films structured such that a first hole and a second hole exist through the first and second passivation films; a pixel electrode on the second passivation film and at least partially filling the first hole through the first and second passivation films, the pixel electrode connected with the drain electrode via the first hole through the first and second passivation films; a first connection electrode on the second passivation film and connected with the data pad via the second hole; a second connection electrode on the first connection electrode and connected with the first connection electrode; a sensing line over the second passivation film; a common electrode connected with the sensing line; and a data pad electrode having a same material as the common electrode and connected with the data pad through the first connection electrode and the second connection electrode.
