The utility model discloses a splicing type reflecting cover and a backlight device thereof, the splicing type reflecting cover comprises a splicing area, the splicing area comprises a first splicing layer and a second splicing layer which are laminated, the first splicing layer is provided with a first opening hole for accommodating a light-emitting element, the second splicing layer is provided with a second opening hole for accommodating the light-emitting element, and the first splicing layer and the second splicing layer are laminated. The second splicing layer is stacked on the reflecting surface of the first splicing layer, and the size of the second opening is larger than that of the first opening. According to the arrangement, the second opening of the second splicing layer of the splicing area is larger than the first opening of the first splicing layer, and the thickness of the thick opening of the splicing area is reduced equivalently, so that the problem of light blocking of the splicing layers o
