Typically, a cathode 130 is disposed on the display module 120. In this embodiment, the narrow-bezel display device further includes a substrate 110 and a sealing frit 150, and the narrow-bezel display device 1 is packaged by using the sealing frit 150. The display module 120 is located on the substrate 110, the sealing frit 150 is located between the substrate 110 and the upper cover plate 140, the sealing frit 150, the substrate 110 and the upper cover plate 140 form an accommodating section 11, and the display module 120 is disposed in the accommodating section 11.
The upper cover plate 140 is located above the display module 130, and the upper cover plate 140 includes an upper surface 141 and a lower surface 142 opposite to the upper surface 141. The upper plate 140 has a display area 140a and a frame area 140b, the display area 140a faces the display module 120, the display area 140a is located directly above the display module 120, the frame area 140b surrounds the display area 140a, the sealing frit 150 is located below the frame area 140b, and a generally black border appears in the frame area 140 b.
In the present embodiment, the light guide structure 160 is located on the lower surface 142 of the upper cover plate 140 and is located inside the sealing frit 150. As shown in fig. 1, the light guide structure 160 includes a display overlapping area 160a and a frame overlapping area 160b that are adjacent to each other, the display overlapping area 160a overlaps a portion of the display area 140a, and the frame overlapping area 160b overlaps at least a portion of the frame area 140b, that is, the display overlapping area 160a is an area where the light guide structure 160 overlaps the display module 120, and the frame overlapping area 160b is an area where the light guide structure 160 does not overlap the display module 120.

2. The narrow-bezel display device of claim 1, wherein the light guide structure is a micro-lens structure comprising sequentially arranged rhombuses, or wherein the light guide structure comprises at least one layer of diffusion film, and scattering particles are added in each layer of diffusion film.
3. The narrow bezel display apparatus of claim 2, wherein the light guiding structure comprises a plurality of diffusion films stacked in a bottom-up order, and refractive indices of the plurality of diffusion films increase in a bottom-up order.
4. The narrow bezel display device of any of claims 1-3, further comprising a sealing frit located between a bezel region of the substrate and an upper cover plate, wherein the light guide structure is located inside the sealing frit, and wherein the second region of the additional light guide structure is located at least partially above the sealing frit.
5. The narrow bezel display apparatus of claim 1, wherein the additional light guiding structure comprises a plurality of layers of the additional diffusion films stacked in a bottom-up order, and refractive indices of the plurality of layers of the additional diffusion films increase in a bottom-up order.
