Abstract: A touch panel is characterized in that one side of a top panel protrudes beyond a side of a bottom panel, signals of sensing areas or conductive layer on the top panel for sensing capacitive variation or voltage variation are transmitted to a bottom surface of the protruded side, signals of sensing areas or conductive layer on the bottom panel for sensing capacitive variation or voltage variation are transmitted to a bottom surface of the top panel through conductive adhesives and to the bottom surface of the protruded side, and the top panel has a flexible PCB formed on the bottom surface of the protruded side to receive those signals. As the flexible PCB is not sandwiched between the top and bottom panels, all layers of the touch panel can be uniformly and tightly bonded and touch insensitivity caused by air penetration into the touch panel can be prevented.
