1. A touch panel comprising:
- a base layer;
a first electrode formed on a surface of the base layer, the first electrode including a first sensor unit, wherein the first sensor unit includes a first conductor; and
a second electrode formed on another surface of the base layer, the second electrode including a second sensor unit, wherein the second sensor unit includes a second conductor,wherein a shape of the first conductor is different from a shape of the second conductor,wherein a resistance of the first sensor unit is greater than a resistance of the second sensor unit,wherein a first area ratio is greater than a second area ratio,wherein the first area ratio is a ratio of an area surrounded by an outer edge of the first sensor unit to an area on which the first sensor unit is formed, andwherein the second area ratio is a ratio of an area surrounded by an outer edge of the second sensor unit to an area on which the second sensor unit is formed,wherein a filling density of the first conductor in the first sensor unit is smaller than a filling density of the second conductor in the second sensor unit,wherein the first conductor includes a transparent conductive metal oxide, and the transparent conductive metal oxide includes a nano metal and has a plurality of spherical particles or a network structure.
