Abstract: A touch panel is realized that is able to decrease the amount of dead space at the periphery of the touch panel and that has highly accurate touch panel sensitivity. In a touch panel, Y direction conductive patterns are arranged so as to be separated from wiring patterns in Y direction conductive pattern regions between electrode units of X direction conductive patterns. As a result, in this conductive sheet, it is possible to appropriately prevent the occurrence of parasitic capacitance resulting from the Y direction conductive patterns and the wiring patterns. Therefore, in a touch panel device or the like that uses such a touch panel, it is possible to effectively prevent the generation of noise that overlaps sense signals as a result of the above-mentioned parasitic capacitance, thereby making it possible to realize highly accurate touch panel sensitivity.

Abstract: Provided is a touch-panel-equipped display device that is capable of detecting a touch on a side surface of a case (1) at a high accuracy by a simple controlling operation, without any hardware such as expensive sensors being provided additionally. In the touch-panel-equipped display device, a side surface electrode part can be electrically connected by capacitive coupling with a Y-direction electrode part. A change in capacitive coupling when the side surface electrode part is touched by a finger or the like, therefore, is reflected in a sense signal acquired by the Y-direction electrode part. In other words, in the touch-panel-equipped display device, a touch on the side surface electrode part can be detected using the sense signal. The touch-panel-equipped display device, therefore, is capable of detecting a touch on the side surface electrode part by using hardware and signal processing for touch detection in a conventional touch panel.
