1. A display device, wherein a display region and a non-display region are defined on the display device and comprises:
a substrate;
a non-organic insulation layer disposed on a side of the substrate; wherein a first groove is defined in the non-organic insulation layer corresponding to the non-display region, an opening of the first groove is away from the substrate, and a metal retaining wall is disposed in the first groove;
a light-emitting layer disposed on a side of the non-organic insulation layer away from the substrate; and
an encapsulation layer disposed on a side of the light-emitting layer away from the substrate and extending from the display region to the non-display region,
wherein the encapsulation layer is overlapped with the first groove in the non-display region, and a first gap is between an edge of the encapsulation layer and an edge of the non-organic insulation layer;
wherein the non-display region comprises a first wiring region provided with a low level line, the first groove is located within the first wiring region, and the metal retaining wall is electrically connected to the low level line;
wherein the display device further comprises a dam disposed on the non-organic insulation layer and located at the edge of the non-organic insulation layer, and the dam is separated from the encapsulation Layer;
wherein the first groove is defined in an annular shape around the display region, and an orthographic projection of the metal retaining wall in a plane perpendicular to a direction extending from the display region to the non-display region entirely overlaps an orthographic projection of each of two side surfaces of the first groove in the direction extending from the display region to the non-display region in the plane; and
wherein the display device comprises a first metal layer disposed on the side of the non-organic insulation layer away from the substrate, the first metal layer comprises a plurality of peripheral wirings disposed in the non-display region, and the metal retaining wall disposed in the first groove is electrically connected to at least one of the peripheral wirings.
