Abstract

A touch-sensitive panel including a substrate, a plurality of sensing electrodes and a decoration layer is disclosed. The substrate has a touch-sensitive region and a decoration region around the touch-sensitive region. A portion of the decoration region is a semi-transparent region. The sensing electrodes are disposed on the touch-sensitive region and interlaced to each other. The decoration layer is disposed on the decoration region. The decoration layer has a meshed pattern in the semi-transparent region. The meshed pattern has a plurality of non-transparent mesh dots. The area ratio of the non-transparent mesh dots in the semi-transparent region is used to regulate the light transmittance of the semi-transparent region. In another embodiment, the meshed pattern has a plurality of transparent mesh holes. The area ratio of the transparent holes in the semi-transparent region is used to regulate the light transmittance of the semi-transparent region.
