Abstract

The invention provides a display panel and a display device. The display panel comprises a pixel driving circuit, a driving transistor and a first connecting portion. The pixel driving circuit comprises scanning lines, data lines and a power line, the scanning lines are used for transmitting scanning signals, the data lines are used for transmitting data signals, and the power line is used for transmitting constant voltage signals; the scanning lines are positioned on a first metal layer, the power line is positioned on a second metal layer, the data lines are positioned on a third metal layer, and the second metal layer is positioned between the first metal layer and the third metal layer; a gate electrode of the driving transistor is positioned on the first metal layer and is connected with the first connecting portion; the power line is positioned between the data lines and the first connecting portion. The display panel and the display device have the advantages that coupling parasitic capacitance of the data lines and first coupling portion can be diminished, offset of driving currents of the driving transistor can be diminished, and interference on the luminescence intensityof organic luminescence components can be diminished.

Description

【Technical field】 [0001] The present invention relates to the technical field of organic light-emitting display, in particular to a display panel and a display device. 【Background technique】 [0002] At present, the development trend of organic light-emitting display technology is to increase resolution and reduce pixel size; however, the parasitic capacitance therein has greater interference on the display screen. 【Content of invention】 [0003] In order to solve the above technical problems, the present invention provides a display panel and a display device. [0004] In one aspect, a display panel includes a pixel driving circuit, and the pixel driving circuit includes scanning lines for transmitting scanning signals, data lines for transmitting data signals, and power lines for transmitting constant voltage signals; [0005] The scan lines are located on the first metal layer, the power lines are located on the second metal layer, the data lines are located on the thi...
