Problems solved by technology

The touch lead 04 extends from the display area to the non-display area, and needs to cross over the first barrier part 021 and the second barrier part 022, and there is a thickness difference on both sides of the second barrier part 022, and the etching process is relatively difficult. It is easy to cause residues of conductive glue, metal and other conductive materials, which will lead to short circuit of the touch leads and affect the performance of the display panel

Abstract

The present invention discloses a display panel and a display device, and belongs to the technical field of display. The display panel comprises a touch lead, a connecting wire, a packaging layer , afirst blocking part and a second blocking part located between the connecting wire and the packaging layer; wherein the packaging layer covers the first blocking part and extends at least between thefirst blocking part and the second blocking part; the packaging layer comprises a first via hole, and the first via hole is located between the first blocking part and the second blocking part; at least part of the touch lead is electrically connected with the connecting line through the first via hole. According to the display panel and the display device, through the arrangement of the via hole,the touch leads are electrically connected through the first via hole between the first blocking part and the second blocking part, and the situation that a short circuit occurs between the touch leads is avoided or reduced, therefore, the touch performance of the display panel is improved, the quality of the display panel is improved, and the use experience of the user is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] See figure 1 , figure 1 It is a schematic cross-sectional view of a display panel provided in the prior art, including a substrate 01 , a barrier portion 02 located on the substrate, an encapsulation layer 03 , multiple touch leads 04 and a planarization layer 05 . Wherein, the barrier part 02 includes a first barrier part 021 and a second barrier part 022 , and the encapsulation layer 03 includes a first encapsulation layer 031 , a second encapsulation layer 032 and a third encapsulation layer 033 . The touch lead 04 extends from the display area to the non-display area, and needs to cross over the first barrier part 021 and the second barrier part 022, and there is a thickness difference on both sides of the second barrier part 022, and the etching process is relatively difficult. It is eas...
