Abstract
Disclosed are a touch panel and a method for manufacturing the same. A touch panel can include a substrate, a transparent electrode base on the substrate, a first transparent electrode on the transparent electrode base and extending in a first direction, and a second transparent electrode on the transparent electrode base and extending in a second direction. A method of manufacturing a touch panel can include preparing a substrate and a transparent electrode base, forming a transparent electrode over the transparent electrode base, and forming an electrode material over the transparent electrode base.
Claims21
A touch panel comprising:
- a transparent electrode base;
- an electrode disposed on the transparent electrode base;
- an insulating layer disposed on the transparent electrode base;
- a wire electrode connected to the electrode, and provided on the transparent electrode base;
- a substrate disposed on the transparent electrode base and comprising a lower surface and an upper surface opposite to the lower surface;
- an outer dummy layer disposed on the wire electrode;
- and
- an optically clear adhesive (OCA) interposed between the lower surface of the substrate and the transparent electrode base,
- wherein the substrate comprises at least one curved surface,
- wherein the wire electrode has a line width in a range of from 10 μm to 100 μm,
- wherein the substrate includes an effective area, in which a position of an input device is detected, and a dummy area provided at an outer portion of the effective area,
- wherein the outer dummy layer and the wire electrode are disposed on the dummy area,
- wherein the dummy area comprises four areas including a top side dummy area, a bottom side dummy area, a left side dummy area, and a right side dummy area of the transparent electrode base,
- wherein a width of each of at least two of the top side dummy area, the bottom side dummy area, the left side dummy area, and the right side dummy area is less than 2 mm,
- wherein the OCA is disposed between the electrode and the lower surface of the substrate, and the electrode is disposed between the transparent electrode base and the OCA, and
- wherein the upper surface of the substrate is exposed to an outside.
