Abstract

The embodiment of the invention relates to a touch display device. The display pad and the touch pad may be arranged on the same side of the display panel by removing a portion of the second substrate after attaching the second substrate on which the touch pad is arranged to the first substrate on which the display pad is arranged to thereby expose the touch pad to the outside. Since the touch pad is located higher than the display pad in a region that does not overlap with the display pad, bonding between the pad and the printed circuit can be easily performed. Since the number of pads that can be arranged is increased, a large-area, high-resolution touch display device can be easily realized.

Description

technical field [0001] Embodiments of the present disclosure relate to touch display devices. Background technique [0002] The growth of a smart society has led to an increase in demand for image display devices and the use of various types of display devices such as liquid crystal displays, organic light emitting displays, and the like. [0003] The display device recognizes a touch on the display panel by a user's finger or a pen, and performs input processing based on the recognized touch to provide a user with more various functions. [0004] A display device capable of recognizing a user's touch may include a plurality of touch electrodes embedded in or disposed on a display panel. The display device may recognize a user's touch by providing a touch driving signal to a plurality of touch electrodes disposed on the display panel and detecting a touch sensing signal from the plurality of touch electrodes. [0005] In order to drive multiple touch electrodes disposed on...
