The present disclosure provides a terminal display assembly and a mobile terminal. The terminal display assembly includes a display screen, a first light-transmissive cover plate, a light-shielding member and a second light-transmissive cover plate. The display screen defines a first through hole. The first light-transmissive cover plate is provided on the display screen, and defines a second through hole. The second through hole has a size larger than that of the first through hole to form a supporting surface on the display screen. The light-shielding member has a bottom wall and a side wall. The side wall forms a receiving space and is adjacent to the first light-transmissive cover plate. The bottom wall is provided on the supporting surface, and defines a third through hole. The second light-transmissive cover plate is provided within the receiving space to cover the first through hole and the third through hole.
