Abstract

The present invention relates to a touch-sensing panel including an electrode-integrated window, and a manufacturing method thereof. The disclosed touch-sensing panel includes a transparent window and a wiring unit. A sensing electrode is formed in a certain pattern on one surface of the transparent window, and the transparent window allows touching on the opposite surface to the plane where the sensing electrode is formed. The wiring unit is connected to the sensing electrode, and the sensing electrode is integrated with the transparent window. According to the invention, it is used the transparent window in which the sensing electrode is integrated with the one surface so that the manufacturing processes may be simplified and the yield may be increased.
