TOUCH SCREEN DISPLAY APPARATUS

摘要

A touch screen display device is provided to form a sensor spacer having a stepped portion to increase an effective contact area between the sensor spacer and a sensor pad so as to improve an electrical characteristic and maintain a cell gap of an LCD(Liquid Crystal Display) panel all the time. A touch screen display device includes a first insulating substrate(10), sensor pads(84,85), a second insulating substrate(110), a sensor spacer(140), a common electrode(150), and a supporting spacer(145). The sensor pad is formed on the first insulating substrate. The second insulating substrate is opposite to the first insulating substrate. The sensor spacer is formed on a portion of the second insulating substrate, which corresponds to the sensor pads, at a distance from the sensor pads and has a stepped portion. The common electrode is formed on the sensor spacer. The supporting spacer is interposed between the first and second insulating substrates and maintains a cell gap.
