1. A mobile terminal having a stylus pen, the mobile terminal comprising:
- a touch panel having a plurality of touch panel electrodes;
a display disposed to overlap the touch panel;
a controller operably coupled with the display; and
a stylus pen configured to transmit and receive an electrical signal to and from the touch panel using capacitive coupling,wherein the stylus pen comprises;
a main body;
a pen tip formed of a conductor and protruding to outside of the main body to apply a touch to the touch panel; and
an LC circuit provided within the main body, configured to include an inductor and a capacitor, and electrically connected to the pen tip to generate capacitive coupling between the touch panel and the stylus pen,wherein the controller is configured to cause the display to;
display an image corresponding to a touch trace of the stylus pen on the basis of a touch applied by the stylus pen; and
display the image in different manners according to a degree to which the pen tip is tilted, andwherein, in a state in which the image is displayed, when a drag touch is applied in a state in which the pen tip is tilted at a slope equal to or greater than a preset slope, the controller is further configured to delete the image overlapping a trace of the drag touch.
