It further optionally, can also be in first substrate 201 close to the side of the second substrate 204, and in the second substrate
204, close to the side of first substrate 201, are respectively provided with support column 203.In general, support column 203 and lens jacket 205 are all set
First substrate 201 is placed in close to the side of the second substrate 204, it is contemplated that the concaveconvex structure of lens group 205, according to existing technique
Level, the difficulty for forming support column 203 are larger.Therefore, it is alternatively possible to which support column 203 and lens jacket 205 are respectively arranged at
On different substrates.
Optionally, the first both alignment layers are photo-alignment layer.
Specifically, when the first both alignment layers are provided with support column far from the side of first substrate, support column and the first orientation
There are differences in height between layer, if being easy to cause orientation power uneven using friction matching, influence the orientation effect of the first both alignment layers
Fruit.And light orientation is the light irradiation both alignment layers using specific wavelength to realize orientation, belongs to contactless orientation, it can be to avoid rubbing
Wipe the non-uniform problem of orientation power caused by orientation.
Optionally, the second both alignment layers are photo-alignment layer.Specifically, when the second both alignment layers are arranged far from the side of the second substrate
When having support column, there are differences in height between support column and the second both alignment layers, if being easy to cause orientation power not using friction matching
Uniformly, the orientation effect of the second both alignment layers is influenced.And light orientation is the light irradiation both alignment layers using specific wavelength to realize orientation,
Belong to contactless orientation, it can be to avoid the non-uniform problem of orientation power caused by friction matching.
It should be noted that, for the second both alignment layers 206 of the side of not lens jacket, can also be adopted still by taking Fig. 9 as an example

Referring to FIG. 10, the side pair when along the direction X perpendicular to first substrate 201, from first substrate 201 far from the second substrate 204
When first substrate 201 applies pressure, first substrate 201 can be bent to the direction close to the second substrate 204.Appointed by being rationally arranged
It anticipates the density of adjacent support column, when first substrate 201 is bent, due to the supporting role of support column 203, in general face pressure
It tests under pressure, it can be to avoid the contact of the first both alignment layers 202 and the second substrate 204 on first substrate 201；It is maximum applying
Face pressure when testing pressure, the second both alignment layers 206 in the first both alignment layers 202 and the second substrate 204 on first substrate 201 can
Not contact, pressure when being also possible to only contact but contact is zero.
Herein, mould group can be switched for the 2D/3D of production, must satisfy the condition of face pressure test before factory.In face
When pressure test, one or two into first substrate or the second substrate apply test pressure, if there is panel generation is disconnected
It splitting, then it represents that it is unqualified that mould group can be switched in 2D/3D, on the contrary, if panel is not broken, and without transfer phenomenon, then it represents that it closes
Lattice.In this process, the face pressure test pressure of application needs to reach preset value, this preset value can be one and be allowed to
Maximum pressure value, when applying the maximum pressure value, panel cannot be broken, and cannot occur to transfer phenomenon.And this most
Under big face pressure test value, in a kind of the first both alignment layers 202 and the second substrate 204 preferably on first substrate 201
Second both alignment layers 206 can not contact, and pressure when being also possible to only contact but contact is zero, to guarantee that panel will not break
It splits, will not occur to transfer phenomenon.
Further, since the second both alignment layers 206 are formed in side of the lens jacket 205 far from the second substrate 204, and the first orientation
Layer 202 is formed on first substrate 201, and therefore, the adhesion strength between the second both alignment layers 206 and lens jacket 202 is matched less than first

When press contacts, the second both alignment layers 206 are transferred to the first both alignment layers 202.Therefore, by matching in the first both alignment layers 202 and second
To support column 203 is arranged between layer 206, even if can still be kept away when first substrate 201 or the second substrate 204 are squeezed
Exempt to generate contact pressure between the first both alignment layers 203 and the second both alignment layers 206, and then the second both alignment layers 206 is avoided to be transferred to
In first both alignment layers 202, it is ensured that the quality of the first both alignment layers 202 and the second both alignment layers 206 guarantees the first both alignment layers 202
With the second both alignment layers 206 to the fixed effect of the initial position of liquid crystal molecule.
