Abstract

A touch-sensing substrate including a substrate, a patterned conductive layer and a patterned insulating layer is provided. The substrate has a plurality of first striped regions and a plurality of second striped regions. The first striped regions are intersected with the second striped regions to define a plurality of sensing-pad disposition regions. The patterned conductive layer includes a plurality of sensing pads disposed in the sensing-pad disposition regions. The patterned insulating layer is disposed on the first striped regions and the second striped regions. The patterned insulating layer and the patterned conductive layer are spliced to form a patterned light-shielding layer. The patterned light-shielding layer has a plurality of enclosed notches arranged in array, wherein parts of the enclosed notches are surrounded by the patterned conductive layer, and other parts of the enclosed notches are surrounded by the patterned conductive layer and the patterned insulating layer.
