Abstract
Disclosed herein is a touch screen panel detecting a capacitive touch input applied by a finger or a touch input means having conductivity like the finger. According to the present invention, the touch screen panel includes: a touch pad forming touch electrostatic capacity (Ct) between the touch pad and the touch input means; and a sensor signal line connecting the touch pad and a touch integrated circuit (IC) to transmit a Ct signal changed on the touch pad to the touch IC, wherein when a resistance value varying with a distance between the touch pad and the touch IC is lower than or equal to a set value, the sensor signal line forms a resistance compensation pattern compensating for the resistance value.
