Display panel and display device

A display device, comprising a power module and a display panel, wherein the power module is configured to provide driving power to the display panel to drive the display panel to perform image display, and the display panel comprises a substrate, a pixel definition layer, a partition structure, and a plurality of sub-pixels, and the pixel definition layer, the partition structure, and the plurality of sub-pixels are located on the substrate;

• the pixel definition layer defines a plurality of pixel openings;
• the plurality of sub-pixels are disposed in the plurality of pixel openings in one-to-one correspondence;
• the partition structure is disposed on the pixel definition layer and surrounds each of the plurality of pixel openings;
• the substrate comprises a first conductive layer, the first conductive layer comprises a plurality of reference voltage lines, and the plurality of reference voltage lines are configured to provide first reference-signals;
• and the first reference-signals are at least indicative of controlling the plurality of sub-pixels for image display;
• and
• the partition structure comprises a second conductive layer, the second conductive layer comprises a plurality of first signal-lines;
• at least a part of the pixel definition layer is provided with a conductive portion, and the conductive portion penetrates through the pixel definition layer;
• and the plurality of first signal-lines are electrically connected to the plurality of reference voltage lines through the conductive portion.
