Abstract
Provided are (i) a touch panel substrate improved in uniformity of in-plane light transmittance and (ii) an electronic device employing the touch panel substrate. A plurality of first sensor electrodes (11) are formed by dividing first conductor lines (13). At least one of a pair of ends of the first conductor lines (13), which pair of ends face each other via a dividing line along which the first conductor lines (13) are divided, has a wide width part (40) which is wider than the other part of the first conductor lines (13), when viewed from above.
Claims12
A touch panel substrate comprising:
- a substrate;
- and
- an electrode layer provided on the substrate,
- the electrode layer being made up of conductor lines uniformly arranged in a net-like pattern on the substrate,
- the conductor lines being divided into pieces so that the pieces of the conductor lines constitute a respective plurality of electrodes,
- at least one of a pair of ends of the conductor lines, which pair of ends face each other via a dividing line along which each of the conductor lines is divided, having a wide width part which is wider than the other part of the conductor lines, when viewed from above.
A method of manufacturing a touch panel substrate including a substrate and an electrode layer provided on the substrate, the method comprising the steps of:
- uniformly forming conductor lines in a net-like pattern on a plane surface of the substrate so that the conductor lines have a wide width part at a position other than an intersection at which the conductor lines intersect each other, the wide width part being wider than the other part of the conductor lines;
- and
- forming a plurality of electrodes by dividing the conductor lines across the wide width part, the plurality of electrodes including the conductor lines arranged in the net-like pattern.
