Cai in order to guarantee the first alignment mark 311 and the second alignment mark 321 within the scope of ultraviolet light wave to infrared waves
It is profiling, therefore, choose generally transparent as the magneto-optic memory technique of the first alignment mark 311 and the second alignment mark 321.
So, when display panel 3 is applied to display device, it often will appear asking for the frame light leakage of display device
Topic.
In the prior art, it by taking liquid crystal display as an example, usually utilizes for being bonded display panel 3 and upper polaroid 302
Adhesive layer 7 blocks transparent the first alignment mark 311 and the second alignment mark 321.However, as shown in fig. 6, due to technique original
Cause, during practical volume production, the upper polaroid 302 being attached on display panel 3 has certain attaching tolerance, and/or, it uses
There is certain attaching tolerance, above-mentioned patch between bonding display panel 3 and the adhesive layer 7 and upper polaroid 302 of upper polaroid 302
Attached tolerance is usually 0~0.3mm.So, when liquid crystal display is shown, a part of light of the sending of backlight module 4
It can pass through the first alignment mark 311 and the second alignment mark 321, so as to cause the frame light leakage of liquid crystal display.

The embodiment of the present invention provides a kind of beneficial effect phase to cassette method, with aforementioned a kind of pair of box device of display panel
Together, details are not described herein.
On the basis of the above, after the completion of by display panel 3 to box, display panel 3 to cassette method further include: such as Fig. 4 institute
Show, forms light-shielding structure 34 away from 32 side of the second substrate in first substrate 31.Light-shielding structure 34 is located at the periphery of display panel 3
The area 62 and orthographic projection of the first alignment mark 311 on the display face is completely covered in its orthographic projection on the display face.
Herein, due to first carrying out first substrate 31 and the second substrate 32 to box, then shading knot is formed on display panel 3
Structure 34, therefore, light-shielding structure 34 will not influence the propagation that the polarised light of first substrate 31 is emitted to from optical transmitting set 8, will not
Influence the propagation for the polarised light being irradiated on optical receiver 9 from the second substrate 32.
In some embodiments, the orthographic projection of light-shielding structure 34 on the display face is completely covered the first alignment mark 311 and exists
Orthographic projection on display surface.Wherein, the orthographic projection of light-shielding structure 34 on the display face is being shown with the first alignment mark 311 just
Orthographic projection on face is completely overlapped；Alternatively, the first alignment mark 311 is completely covered in the orthographic projection of light-shielding structure 34 on the display face

Cai in order to guarantee the first alignment mark 311 and the second alignment mark 321 within the scope of ultraviolet light wave to infrared waves
It is profiling, therefore, choose generally transparent as the magneto-optic memory technique of the first alignment mark 311 and the second alignment mark 321.
So, when display panel 3 is applied to display device, it often will appear asking for the frame light leakage of display device
Topic.
In the prior art, it by taking liquid crystal display as an example, usually utilizes for being bonded display panel 3 and upper polaroid 302
Adhesive layer 7 blocks transparent the first alignment mark 311 and the second alignment mark 321.However, as shown in fig. 6, due to technique original
Cause, during practical volume production, the upper polaroid 302 being attached on display panel 3 has certain attaching tolerance, and/or, it uses
There is certain attaching tolerance, above-mentioned patch between bonding display panel 3 and the adhesive layer 7 and upper polaroid 302 of upper polaroid 302
Attached tolerance is usually 0~0.3mm.So, when liquid crystal display is shown, a part of light of the sending of backlight module 4
It can pass through the first alignment mark 311 and the second alignment mark 321, so as to cause the frame light leakage of liquid crystal display.
Based on this, in the embodiment of the present invention, light-shielding structure 34 can be set away from 32 side of the second substrate in first substrate 31,
And the orthographic projection of the first alignment mark 311 on the display face is completely covered in the orthographic projection of light-shielding structure 34 on the display face, in this way
One, it can prevent light from projecting display device by the first alignment mark 311 and the second alignment mark 321, cause light leakage phenomena.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
