    • A display device ( 100 ) includes a plurality of display panels having a display region ( 31a, 31b ) and a frame region ( 30a, 30b ) . The plurality of display panels include first and second display panels adjoining each other ( 10a, 10b ); the frame region ( 30a ) of the first display panel is overlapped by a side face ( 18b ) of the second display panel so that an angle ¸ defined by viewer-side surfaces ( 17a, 17b ) is more than 0° but less than 180°; first and second light guide elements ( 20a, 20b ) are disposed on the viewer's side of peripheral display regions ( 32a, 32b ); the light guide elements have an incident face, an outgoing face, and a plurality of light guiding portions; the distance between the incident face and the outgoing face increases away from the peripheral display region and toward the frame region; the volume of the first light guide element is larger than the volume of the second light guide element; and the outgoing faces of the first and second light guide elements are covered by a functional film. According to the present invention, there is provided a direct-viewing type display device which is easier to produce or incurs lower cost than conventionally, and in which the frame regions of the display panels, or a joint in the case of tiling, are obscured.
