Provided is a matrix switching type touch panel including a plurality of touch pads disposed in a visible area on a substrate in a dot matrix format, the touch pads spaced from one another, and a plurality of signal lines disposed in a space between the touch pads, each connecting a touch pad and a touch driving circuit of an invisible area. The panel comprises: unit electrodes made of a transparent electroconductive material and disposed within the visible area; touch pad areas each determined in an area corresponding to each touch pad; signal line areas each determined in an area corresponding to each signal line; and bridges electrically connecting the plurality of unit electrodes disposed in each touch pad area and each signal line area. The unit electrodes are arranged in a zigzag format with respect to a first axis parallel to the signal lines.
