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;
a plurality of dummy electrodes in an electrical floating formed on the first layer;
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 first layer of the substrate; and
an insulating layer on the first 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, and
each of the dummy electrodes is formed between each of the first individual electrodes and each of the second individual electrodes.
