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 first layer of the substrate;
a plurality of first connecting electrodes which connect to each of the first individual electrodes in a first direction;
an inorganic insulating layer formed on the first individual electrodes and first connecting electrodes;
a plurality of second individual electrodes arranged in a matrix on the inorganic insulating layer;
a plurality of second connecting electrodes on the inorganic insulating layer which connect to each of the second individual electrodes in a second direction different from the first direction; and
a plurality of dummy electrodes in an electrical floating surrounding each of the second individual electrodes on the first layer,
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.
2. The touch panel according to claim 1 , wherein
the first individual electrodes and the second individual electrodes have a diamond shape.
3. The touch panel according to claim 1 , wherein a space between one of the dummy electrodes and one of the second individual electrodes is from 20 pm to 30 pm.
4. The touch panel according to claim 3 , further comprising:
the first individual electrodes, the second individual electrodes, and the dummy electrodes are made of transparent conductive film.
