Abstract
A touch panel including a substrate, first connecting pads, circuit units, and ground lines is provided. Each circuit unit includes a signal line, first electrodes, second electrodes, first connecting lines, and second connecting lines. The signal line extends along a first direction and includes a first portion and a second portion. The first portion is located between a first side of the substrate and the second portion. The first electrodes are disposed beside the first portion, and the second electrodes are disposed beside the second portion. The first connecting lines respectively connect the first electrodes to the corresponding first connecting pads. The second connecting lines respectively connect the second electrodes to the corresponding first connecting pads through a trace region located beside the first portion, wherein the trace region and the first electrodes are respectively located at two opposite sides of the first portion.
