Embodiment Construction

[0016] In the following description of the embodiments, it is to be understood that when a layer (or film), region, pattern or structure is referred to as being "on" or "under" a substrate, another layer (or film), region, liner or pattern When , the layer (or film), region, pattern or structure may be located "directly" or "indirectly" on another layer (or film), region, pattern or structure, or one or more intervening layers may also be present. The position of each such layer will be described with reference to the drawings.

[0017] The thickness and size of each layer (or film), region, pattern or structure shown in the drawings may be modified, so the size of elements shown in the drawings does not utterly reflect an actual size.

[0018] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0019] refer to Figure 1 to Figure 3 A touch panel according to an embodiment may include a substrate 100 , a sensing electrode 300 ,...

Abstract

A touch panel of the embodiment includes a substrate (100); a sensing electrode (300) on the substrate (100); wires to electrically connect the sensing electrode (300); a first ground electrode (510) between the sensing electrode (300) and the wire (400); and an overlap part (OL) where the first ground electrode (510) overlaps with the sensing electrode (300). A touch panel of another embodiment includes a substrate (100) on which an active area (AA) and an unactive area (UA) are defined; a sensing electrode (300) on the active area (AA); a wire (400) disposed on the unactive area (UA) to electrically connect the sensing electrode (300); and a first ground electrode (510) disposed on the active area (AA) between the sensing electrode (300) and the wire (400).

Description

technical field [0001] This embodiment relates to a touch panel and a touch device including the touch panel. Background technique [0002] The touch panel is mounted on the display surface of an image display device such as a cathode ray tube (CRT), a liquid crystal display (LCD), a field emission display (FED), a plasma display panel (PDP), and an electroluminescent device (ELD) , so that the user inputs predetermined information into the electronic appliance by pressing the touch panel while viewing the image display device. [0003] In such a touch panel, electrical signal interference may occur due to static electricity or ESD, degrading the accuracy of touch. Contents of the invention [0004] The embodiment provides a touch panel and a touch control device including the touch panel, and the touch panel can improve the accuracy of touch. [0005] According to this embodiment, there is provided a touch panel, which includes: a substrate; sensing electrodes located o...
