Display module structure and display device

A display device, comprising a liquid crystal display panel and a display module structure, the display module structure configured to support an optical assembly, the optical assembly comprising a light-emitting device for providing a light source for the liquid crystal display panel, wherein the display module structure comprises:

• a support plate comprising a support surface, a bottom surface, an interference surface connected between the support surface and the bottom surface, a groove, and at least one first interference member, wherein the support surface is configured for disposition of the optical assembly, the first interference member is disposed on the interference surface, and the support surface is located at a vertical level higher than a vertical level of the first interference member;
• the groove is recessed from the interference surface, and the first interference member is located in the groove and protrudes out of the interference surface;
• and
• a frame comprising a retaining wall and at least a first interference portion arranged on the retaining wall, the retaining wall disposed around the support plate, the first interference portion of the frame is located at a bottom edge of the retaining wall and extends in a direction toward the first interference member and comprises a fastening slot and a limiting wall surrounding the fastening slot, the fastening slot engages with the first interference member, an outer surface of the limiting wall is located in the groove, a width between opposite ends of the limiting wall is equal to a width of the groove, the limiting wall comprises a guiding edge disposed at a corner of the limiting wall close to the interference surface, wherein the guiding edge is an inclined surface or a curved surface, an abutting surface of the first interference member abuts against the limiting wall below the fastening slot, and the first interference member is surrounded by the limiting wall, so as to complete fastening between the first interference portion and the first interference member to fix the frame to the support plate.
