Abstract
Provided are a touch display device and a display panel. A bridge pattern connecting touch electrodes is provided in an open area in which a single color filter is provided, so as not to overlap an area in which a plurality of color filters are provided. Short circuit defects between the touch electrodes and touch lines are prevented, and improved touch sensing or accurate touch sensing is enabled.
Claims10
A touch display device, comprising:
- a display panel including:
- an open area of a subpixel configured to emit light;
- a single color filter disposed on the open area;
- a black strip area adjacent to the open area;
- and
- a plurality of color filters overlapped with each other in the black strip area, the black strip area blocking light emission at least partially due to the overlapping of the plurality of color filters;
- a plurality of touch electrodes disposed inside the display panel and separated from each other;
- a plurality of touch lines connected to the plurality of touch electrodes, respectively, to apply a touch driving signal to the plurality of touch electrodes;
- and
- at least one bridge pattern connected to touch electrodes disposed in adjacent subpixels in the open area, among the plurality of touch electrodes.
