Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and aims to improve the potential stability of nodes in a pixel circuit. The display panel comprises a substrate and a plurality of pixel circuits located on the substrate, and each pixel circuit comprises a driving transistor which is connected with a connecting wire; the light-transmitting conductive part comprises a light-transmitting conductive material, and the light-transmitting conductive part and the connecting line segment are at least partially overlapped in the direction perpendicular to the plane where the substrate is located.

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] Organic Light-Emitting Diode (OLED), which has the advantages of low power consumption, low cost, self-illumination, wide viewing angle, and fast response, has become a research hotspot in the field of display. [0003] To realize image display, the display panel includes pixel circuits and light emitting elements, and the pixel circuits are electrically connected to the light emitting elements to drive the light emitting elements to emit light. In the existing pixel circuit, the coupling effect between different nodes is relatively large, and the stability of the potential of the nodes is low, which in turn adversely affects the luminous brightness of the light emitting element. 【Content of invention】 [0004] In view of this, an embodiment of the present invention provides a display panel and a ...
