Abstract

A touch panel including a substrate, first electrodes, second electrodes, and an insulating layer is provided. Each first electrode includes first pad portions and first connection portions, and each first connection portion connects two adjacent first pad portions. Each second electrode includes second pad portions and second connection portions, and each second connection portion connects two adjacent second pad portions. The first electrodes and the second electrodes are located on the same side of the substrate, and the first connection portions and the second connection portions cross each other. The insulating layer is located between the first connection portions and the second connection portions. The first electrodes and the second electrodes include a metal mesh layer and a transparent conductive layer. At least one of the first connection portions and the second connection portions includes the metal mesh layer.

Dependent claims

A touch panel, comprising:

a substrate;
a plurality of first electrodes, disposed on the substrate, wherein each of the first electrodes comprises a plurality of first pad portions and a plurality of first connection portions, and each of the first connection portions directly contacts and connects two adjacent first pad portions;
a plurality of second electrodes, disposed on the substrate, wherein each of the second electrodes comprises a plurality of second pad portions and a plurality of second connection portions, and each of the second connection portions directly contacts and connects two adjacent second pad portions;
and
an insulating layer, wherein the first electrodes and the second electrodes are located on the same side of the substrate, the first connection portions and the second connection portions cross each other, and the insulating layer is located between the first connection portions and the second connection portions, such that the first electrodes and the second electrodes are electrically insulated from each other,
wherein the first electrodes and the second electrodes comprise a metal mesh layer and a transparent conductive layer, and at least one of the first connection portions and the second connection portions comprises the metal mesh layer.
