Abstract

A touch panel is provided and includes a substrate having first and second face sides, the first face side being an inputting face side and the second face side being opposite to the first face side; a conductive member that is arranged on the substrate, and that configures input position detecting electrodes in an inputting region; a mounting terminal in a peripheral region that is outside the inputting region in a plan view; peripheral wiring lines disposed in the peripheral region, each having a first end electrically connected to the mounting terminal and a second end connected to one of the input position detecting electrodes; a first light blocking layer arranged on the substrate so as to cover at least a part of the peripheral wiring lines when viewed from the first face side of the substrate; and a second light blocking layer arranged between the substrate and the peripheral wiring line, wherein the first light blocking layer overlaps at least a part of the second light blocking layer so as to partly sandwich the peripheral wiring lines between the first light blocking layer and the second light blocking layer.
