## Abstract

The present invention relates to a touch panel for detecting capacitive touch input from a human finger or a touch input tool having similar conductive characteristics thereto, and more particularly, to a touch panel having a sensing electrode with improved visibility. The touch panel having a sensing electrode with improved visibility includes: a plurality of sensing electrodes formed of a transparent conductive material to generate a touch capacitance (Ct) upon approach or touch by a touch means; and a plurality of sensor signal lines transmitting a touch signal generated by the sensing electrodes to a touch IC, wherein both the sensing electrodes and the sensor signal lines are formed in a repeated zigzag shape.
