Touch panel
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.
1. A touch panel comprising:
a substrate;
a plurality of first individual electrodes arranged in a matrix on a layer of the substrate;
a plurality of first connecting electrodes which connect to each of the first individual electrodes in a first direction;
a plurality of second individual electrodes arranged in a matrix;
a plurality of second connecting electrodes which connect to each of the second individual electrodes in a second direction different from the first direction on the layer of the substrate; and
an insulating layer on the layer of the substrate formed between each of the first connecting electrodes and the second connecting electrodes,
wherein an area of each of the first individual electrodes is smaller than an area of each of the second individual electrodes, and
the number of the first individual electrodes arranged in the second direction is smaller than the number of the second individual electrodes arranged in the first direction.
