Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to a first embodiment of the present application. The first embodiment provides a liquid crystal display device 100, which includes a display panel 10, a first shading ring 20, a first polarizer 31, a second polarizer 32, a backlight module 40, a shading glue 50, an optical glue 60 and a cover plate 70.
And a blind hole M is formed in the display panel 10. The liquid crystal 11 is filled in the blind hole M, and the display panel 10 includes a light-emitting side 10a and a backlight side 10b opposite to the light-emitting side 10 a.
Specifically, the first light shielding ring 20 is formed on the backlight side 10b, and the first light shielding ring 20 correspondingly surrounds the outer periphery of the blind hole M.
The first polarizer 31 is disposed on the backlight side 10b of the display panel 10. The first polarizer 31 is provided with a first through hole 31d, and the first through hole 31d is arranged corresponding to the blind hole M. The portion of the first polarizer 31 near the first through hole 31d is attached to the first shading ring 20.
The light emitting side of the backlight module 40 is disposed on the first polarizer 31. The backlight module 40 is provided with a second through hole 40d, and the second through hole 40d is arranged corresponding to the blind hole M and communicated with the first through hole 31 d.
The light blocking paste 50 is disposed in the first through hole 31d and the second through hole 40 d. The light shielding glue 50 is adhered to the peripheral wall of the second through hole 40d and extends to be adhered to the first light shielding ring 20.
The second polarizer 32 is disposed on the light emitting side 10a of the display panel 10. A third through hole 32d is formed in the second polarizer 32, and the third through hole 32d is arranged corresponding to the blind hole M.
The optical adhesive 60 is disposed on the second polarizer 32. The cover plate 70 is disposed on the optical cement 60.
The liquid crystal display device 100 of the first embodiment is provided with the first light shielding ring 20 on the backlight side 10b of the display panel 10, and the first light shielding ring 20 covers a portion of the first polarizer 31 and extends to cover a portion of the light shielding glue 50. When a gap N occurs between the light shielding adhesive 50 and the first polarizer 31, a part of light of the backlight module 40 passes through the gap N and is radiated onto the first shading ring 20, and is shielded by the first shading ring 20, so that the light of the backlight module 40 is prevented from entering the blind hole M from the gap N, and the phenomenon of poor light leakage caused by forming a hole white edge is avoided.
It should be noted that fig. 1 only shows a schematic structural diagram of the gap N generated between the light shielding glue 50 and the first polarizer 31, and it cannot be understood that the gap N is necessarily generated in the liquid crystal display device 100 according to the first embodiment, for example, the light shielding glue 50 and the first polarizer 31 may be connected, i.e., the gap N does not exist.
Specifically, for example, when the liquid crystal display device 100 is shipped, the light-shielding adhesive 50 and the first polarizer 31 are connected without a gap N therebetween; however, since the liquid crystal display device 100 shipped in the later stage is in different environmental temperatures, the first polarizer 31 expands and contracts, and the first polarizer 31 and the light shielding adhesive 50 are separated from each other, thereby generating the gap N. That is, the gap N may be generated due to insufficient precision when the light-shielding glue 50 is applied before the factory shipment, or may be generated due to the expansion and contraction of the first polarizer 31 at a later stage, which may cause the first polarizer 31 and the light-shielding glue 50 to be separated from each other. Of course, the liquid crystal display device 100 may not have the gap N. However, whether the gap N is generated or not, the first light-shielding ring 20 is disposed to prevent light of the backlight assembly 40 from entering the blind hole M.
