Abstract:
A direct-viewing type display device according to the present invention includes: at least one display panel having a display region and a frame region formed outside of the display region; and at least one Fresnel lens plate disposed on a viewer side of the at least one display panel with a predetermined interval therefrom. The Fresnel lens plate includes a Fresnel lens region at a position overlapping a region that contains a portion of the frame region of the display panel and a portion of a peripheral display region within the display region that adjoins the portion of the frame region along a first axis. A portion of display light exiting the portion of the peripheral display region is emitted from a region of the Fresnel lens region that overlaps a portion of the frame region, or a region outside the region, toward the viewer side. According to the present invention, there is provided a direct-viewing type display device in which a frame region of a display panel, or a joint in the case of tiling, is made unlikely to be seen, with a structure which is more simple and light-weighted than conventionally.
