  • Publication number: 20230273696
    Abstract: A display device with a touch panel includes a display panel, and a touch panel formed above the display panel. The touch panel includes X electrodes which extend in a first direction, and Y electrodes which extend in a second direction different from the first direction. The X electrodes and the Y electrodes respectively include intersection portions each formed where the X electrodes and the Y electrodes overlap each other, and electrode portions each formed between the intersection portions, wherein the electrode portions of one of the X electrodes is smaller in area than the electrode portions of one of the Y electrodes, and wherein floating electrodes are formed close to the electrode portion of the one of the X electrodes or Y electrodes, and over a reduced portion of the X electrode.
