Problems solved by technology

[0008] Therefore, there is a problem that the performance of touch sensing decreases because the performance for detecting a touch sensing signal decreases as the load of the touch wiring increases.
In addition, there is a problem that the uniformity of touch sensing decreases due to a difference in load depending on the length of the touch wiring or a difference in a point at which the touch wiring is connected to the touch electrode.

Abstract

The invention relates to a touch display device. A part of the touch wiring is disposed on a region surrounded by the touch electrode line on the active region and is electrically connected to the touch electrode line, so that the touch wiring can be disposed on the active region while minimizing the influence of noise. Thus, the touch wiring can be additionally arranged and the connection point of the touch wiring can be freely adjusted without increasing the area for arranging the touch wiring, so that the load of the touch wiring and the sensitivity difference caused according to the position of the touch electrode line are reduced, thereby improving the performance of the touch sensing. The touch display device includes: a plurality of touch electrode lines including two or more touch electrodes disposed on an active area, at least some of the touch electrodes being electrically connected to each other in a first direction or a second direction crossing the first direction; and a plurality of touch wires electrically connected to one touch electrode line, at least a portion of the first touch wire being located on a region surrounded by the touch electrode line electrically connected to the first touch wire.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2020-0082844 filed on July 6, 2020, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Embodiments of the present invention relate to a touch display device. Background technique [0004] The development of the information society has prompted demand for display devices that display images and increased use of various types of display devices, such as liquid crystal display devices, organic light emitting display devices, and the like. [0005] A display device for providing users with more various functions provides a function of recognizing a touch of a user's finger or a pen in contact with a display panel and performing input processing based on the recognized touch. [0006] The display device may include a plurality of touch electrodes disposed on or built in the display panel. T...
