Abstract

A touch pad includes a first conductive pattern layer, a second conductive pattern layer, a first trace, a second trace, a first bonding pad, and a second bonding pad. The first conductive pattern layer includes a first touch electrode extending in a first direction. The second conductive pattern layer includes a second touch electrode extending in a second direction. A first end of the first trace is coupled to the first touch electrode, and a second end of the first trace is coupled to the first bonding pad. A first end of the second trace is coupled to the second touch electrode, and a second end of the second trace is coupled to the second bonding pad. The first direction intersects the second direction.
