EXAMPLE III
Referring to fig. 4, the present embodiment is the same as or similar to the first embodiment and the second embodiment, except that:

In this embodiment, the first curved sub-surface 118 may be disposed corresponding to the sub-pixels of the second pixel in the second sub-pixel region 115.
By arranging the first sub-curved surface 118 and the sub-pixels of the second pixels correspondingly, the light emitted by the second light source 111 passes through each sub-pixel of the second pixels and then passes through the first curved surface corresponding to the sub-pixels one to one, and then is emitted from the area of the display device 100 corresponding to the non-display area 106 of the display panel 102, which is beneficial to improving the definition of the area of the display device 100 corresponding to the non-display area 106 of the display panel 102 during display and improving the display coordination of the display device 100.

Through the arrangement of the first arc surface 117, when an incident angle formed when light emitted by the backlight module 101 passes through a part of light at the rear of the diffusion unit 104 and enters the brightness enhancement film 112 is too large, the part of light is vertically emitted in a region of the display device 100 corresponding to the non-display region 106 of the display panel 102, and the display effect of the display device 100 is improved.
In the above embodiments, by the arrangement of the diffusion unit 104, part of the light energy from the backlight module 101 is emitted from the area of the display device 100 corresponding to the non-display area 106 of the display panel 102, so that not only can the full-screen display of the display device 100 be realized, but also the black splicing seam, which is obvious when a large-size splicing device formed by splicing the display device 100 displays, can be eliminated, and the display effect is improved.
