Display panel and display device

A display device, comprising a display panel, wherein:

• the display panel includes a substrate;
• a display function layer, a first insulating layer, a second insulating layer, and a polarizer arranged on a same side of the substrate;
• and
• a first protective layer and a second protective layer,
• wherein:
• along a first direction, the first insulating layer is located on a side of the display function layer away from the substrate, the second insulating layer is located on a side of the first insulating layer away from the substrate, and the polarizer is located on a side of the second insulating layer away from the substrate, wherein the first direction is perpendicular to a plane where the substrate is located;
• the display panel has a display area and a first non-display area located on one side of the display area along a second direction;
• the first non-display area includes a binding area;
• the polarizer is located in the display area and at least a portion of the first non-display area;
• the second insulating layer and the first insulating layer are located in the display area and at least part of the first non-display area;
• along the first direction, the polarizer, the second insulating layer, and the first insulating layer do not overlap with the binding area;
• the first protective layer is located in the first non-display area;
• along the first direction, the first protective layer is at least located on the side of the second insulating layer away from the substrate, and overlaps with the second insulating layer, the first insulating layer and the binding area;
• the second protective layer is located on the side of the polarizer away from the substrate and covers the polarizer;
• and
• along the first direction, the second protective layer overlaps with at least part of the first protective layer.
