Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and improves the touch precision and mechanical strength of the display panel on the premise of reducing parasitic capacitance of a touch layer and a first electrode. The display panel comprises a pixel definition layer, a light-emitting unit, a first supporting column and a touch layer. The light-emitting unit comprises a first electrode, a light-emitting layer and a second electrode. The first supporting column is located between the pixel defining layer and the first electrode, and the first supporting column is located in the non-opening area of the pixel defining layer; the first electrode covers the light-emitting layer and the first supporting column; the touch layer is located on the side, away from the pixel defining layer, of the first electrode. The touch layer comprises a hollow part, and a first part and a second part which are connected with each other; the orthographic projection of the first part and the orthographic projection of the hollow part are overlapped with the orthographic projection of the first supporting column, the orthographic projection of the second part is not overlapped with the orthographic projection of the first supporting column, and the area of the orthographic projection of the overlapped part of the first part and the first supporting column is smaller than that of the orthographic projection of the first supporting column.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] With the rapid development of display technology and human-computer interaction technology, display panels with touch functions have been more and more widely used. Wherein, the capacitive touch display panel judges the occurrence of the touch by detecting the variation of the capacitance of the touch electrodes before and after the touch. However, in the in-cell touch display panel, since the parasitic capacitance may be generated between the touch layer and the existing metal traces in the display panel, the touch accuracy of the display panel is easily affected. 【Content of invention】 [0003] In view of this, an embodiment of the present invention provides a display panel to improve the touch performance of the display panel. [0004] In view of this, an embodiment of the present invention pr...
