Abstract:
1. A touch screen display apparatus comprising: a first transparent substrate; a gate line and a sensor conductor formed on the first transparent substrate; a data line insulated from and intersecting the gate line and sensor conductor; a second transparent substrate facing the first transparent substrate; a sensor electrode formed on the second transparent substrate so as to correspond to an intersection of the sensor conductor and the data line, the sensor electrode electrically connecting the sensor conductor with the data line when acted upon by an external pressure, a passivation layer formed on the sensor conductor and the data line and having first and second contact holes partially exposing the sensor conductor and the data line, respectively; first and second electrode pads formed on the passivation layer to be connected with the sensor conductor and the data line through the first and second contact holes, respectively; and a planarization pattern formed between the first electrode pad and the first transparent substrate for the purpose of flattening the surface of the first electrode pad and the surface of the second electrode pad, wherein the passivation layer is made of an insulating material; and wherein the planarization pattern is made of the same material on the same plane as the data line.
