The present invention discloses a frame structure for a display device including a metallic back panel having a lateral edge extended from a side of the metallic back panel and a plastic outer frame having two clip parts. The lateral edge is having two side surfaces. The lateral edge is formed integrally with the metallic back panel. An included angle is formed between an inner side of the metallic back panel and an inner side of the lateral edge. A bended corner is formed between an outer side of the metallic back panel and an outer side of the lateral edge. The bended corner is in a shape of an arc. The two clip parts are in a clipping state to clip the two side surfaces of the lateral edge. The plastic outer frame completely encloses the two side surfaces, the included angle and the bended corner by injection molding.
