Abstract: A touch detection module includes: first driving electrodes side by side; first detection electrodes intersecting the first driving electrodes; second driving electrodes on front surfaces of the first driving electrodes corresponding to the first driving electrodes with a touch insulating layer interposed therebetween; second detection electrodes on front surfaces of the first detection electrodes corresponding to the first detection electrodes with the touch insulating layer interposed therebetween; driving switching circuits electrically connecting the second driving electrodes to the respective first driving electrodes corresponding to each other or a low potential voltage source; detecting switching circuits electrically connecting the second detection electrodes to the respective first detection electrodes corresponding to each other or the low potential voltage source; and a touch driving circuit configured to supply touch driving signals to the first driving electrodes and to detect touch detection signals through the first detection electrodes to detect touch position coordinates.
