Touch screen device for compensating distortion of input sensing signal

The present invention relates to a touch screen device which comprises: an electromagnetic resonance (EMR) sensing panel for sensing an input from an electronic pen; a display panel that is installed on a top layer portion of the EMR sensing panel, configured to receive a control signal or a graphic signal from the outside, and displays an image corresponding to the received signal; a bracket that is formed in the form of a plate on corresponding portions of the EMR sensing panel and the display panel to support and protect the EMR sensing panel and the display panel, and has an extension portion that extends from the corresponding portions of the EMR sensing panel and the display panel; and a frequency compensating plate that is formed of a soft magnet installed on the extension portion.
