Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0034] As mentioned in the background art, existing display devices have the problems of attenuation of display brightness and flickering of display screens caused by electric leakage of pixel circuits, which affect the display effect of the display device. The inventors found that the reasons for the above problems are as follows: the pixel circuit in the display device includes a plurality of thin film transistors, and the thin film transistors include driving transistors and switching transistors. Due to various...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes: a substrate; and an array circuit layer which comprises an active layer and a plurality of metal layers, wherein the first metal layer comprises a grid electrode of a driving transistor and a first polar plate of a storage capacitor, the second metal layer comprises a second polar plate of the storage capacitor, the third metal layer comprises a first metal wire, the second polar plate being connected with power supply voltage through the first metal wire; the first polar plate is further connected with an active layer; the multiple metal layers further comprise a second metal wire, the second metal wire is connected with the first metal wire, the vertical projection of the second metal wire on the substrate is overlapped with the vertical projection of the active layer connected to the first polar plate on the substrate, and the vertical projection of the second metal wire on the substrate is seperated from the vertical projections of the first polar plate and the second polar plate on the substrate. According to the technical scheme, the total storage capacitance of the pixel circuit can be increased, the flicker phenomenon of a display image is improved, and the display effect is optimized.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, people have higher and higher requirements for the performance of display devices. Currently, pixel circuits in display panels commonly suffer from electric leakage problems, which will cause changes in display brightness. Especially in the case of low-frequency driving, the problem of display brightness variation caused by electric leakage will also make it easier for human eyes to recognize the flickering phenomenon of the display screen, which affects the display effect of the display device. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device, so as to increase the total storage capacitance in the pixel circuit, improve the flicker phenomenon of the display screen, and op...
