Splicing display device

The invention discloses a tiled display device which is characterized in that a compensation display area adjacent to a tiled area is arranged, the pixel design of the compensation display area is changed, and a light path adjusting structure capable of transferring emergent light of a part of sub-pixel units in the compensation display area to the tiled area and then emitting the emergent light is arranged. In this way, pictures displayed by part of the sub-pixel units of the compensation display area are transferred to the splicing area, the effect of eliminating frames is achieved, and therefore seamless splicing of the display panel can be achieved. Moreover, the first lens structures are arranged on the light-emitting sides of the sub-pixel units, which do not transfer the emergent light rays, in the compensation display area, and the second lens structures are arranged in the splicing area, so that the first lens structures and the second lens structures are utilized to amplify a display picture; the sp
