Abstract
A touch panel includes a substrate, a light-shielding layer, a patterned transparent layer, a reflecting layer, at least one first sensing series, and at least one second sensing series. The substrate has a touch sensing region and a peripheral region. The light-shielding layer is disposed in the periphery region. The light-shielding layer has a patterned opening and a sidewall adjacent to the patterned opening. The patterned opening is configured to provide a mark identifiable by human eyes. The patterned transparent layer is disposed in the peripheral region, and the patterned transparent layer covers a portion of the patterned opening. The patterned transparent layer has an inclined sidewall positioned in the patterned opening. The reflecting layer covers the inclined sidewall and the patterned opening. The first sensing series and the second sensing series are arranged in the touch sensing region to detect a position of a touch point.
