Patent ID: 10788943

Abstract:
Provided is a technique of preventing a decrease in touch detection sensitivity even in the case where an air layer is present between electrodes for touch detection in a mutual capacitance touch panel-equipped display device. A touch panel-equipped display device 1 includes: a substrate 11; a plurality of first electrodes Rx spaced from each other on the substrate 11; a second electrode Tx located around or inside the plurality of first electrodes Rx on the substrate 11, to form a capacitance with each of the first electrodes; and a translucent cover portion C facing the substrate 11. Each of the first electrodes Tx or the second electrode Rx is in contact with the cover portion C, and an air layer AG is interposed between the substrate 11 and the cover portion C in a region in which an electrode not in contact with the cover portion C is located.
