Display module and display device

A display module, comprising:

• a display panel comprising a display area and a non-display area surrounding the display area;
• an optical adhesive layer, wherein the optical adhesive layer is on a light-emitting side of the display panel and covers the display area;
• a cover plate, wherein the cover plate is on a side of the optical adhesive layer facing away from the display panel and covers the display panel and the optical adhesive layer;
• wherein a side of the cover plate facing the optical adhesive layer is provided with a limiting groove for preventing an edge of the optical adhesive layer from overflowing, and at least the edge of the optical adhesive layer is in the limiting groove;
• a polarizer, wherein the polarizer is between the display panel and the optical adhesive layer, and an edge of the polarizer is flush with an edge of the display panel;
• a ground layer, and
• a conductive medium in at least one position;
• wherein the ground layer is on a side of the display panel facing away from the polarizer;
• the conductive medium is coated on a side face of the display panel, and extends to contact with:
• a side of the cover plate facing the display panel, the edge of the polarizer and a side face of the ground layer;
• and
• the optical adhesive layer comprises:
• a main body part covering the display area of the display panel;
• and
• at least one extension part connected with an edge of the main body part;
• wherein the at least one extension part is arranged in one-to-one correspondence with the conductive medium in at least one position;
• and
• the extension part is filled between corresponding conductive medium and the main body part.
