Abstract
A touch-sensing device is provided, which includes a substrate with a central region and a peripheral region, and a first light-shielding layer disposed on the peripheral region, wherein the first light-shielding layer has a first edge adjacent to the central region. The device further includes a touch-sensing layer disposed on the central region, and a part of the touch-sensing layer extends onto the peripheral region to cover a part of the first light-shielding layer. The device also includes a conductive line layer disposed on the first light-shielding layer, and a second light-shielding layer covering at least a part of the first light-shielding layer and at least a part of the conductive line layer. The second light-shielding layer has a second edge adjacent to the central region, and the second edge has a profile roughness that is greater than that of the first edge.
