Structure and driving are simple.
As shown in Fig. 2 such as liquid crystal slit grating 2 is applied in mobile phone small size display device, the first isolated area A,
The long side of first isolated area B and the first isolated area C along first substrate 29, which is set gradually, can more conform to viewing custom, when
So, can also set the first isolated area A, the first isolated area B and the first isolated area C along the first substrate 29 it is short according to
It is secondary to set；Such as liquid crystal slit grating 2 is applied in PAD large scale display devices, the first isolated area A, the first isolated area B
Short side with the first isolated area C along first substrate 29, which is set gradually, can more conform to viewing custom, it is of course also possible to set the
The long side of one isolated area A, the first isolated area B with the first isolated area C along the first substrate 29 is set gradually, herein
Do not limit.When the long side of the first isolated area A, the first isolated area B and the first isolated area C along first substrate 29 is set
When, the first spacer portion 24a by first substrate 29 one it is long while extend to first substrate 29 it is another long while；When the first isolated area
When the short side of A, the first isolated area B and the first isolated area C along first substrate 29 is set, spacer portion 24a is by first substrate 29
A short side extend to another short side of second substrate 29, i.e. the first isolated area A, the first isolated area B and isolated area C without
By being to set or set along the short side of first substrate 29 along the long side of first substrate 29, spacer portion 24a is only by adjacent first
Vertical region A and the first isolated area B, or the first adjacent isolated area B and corresponding first electrode 22 in the first isolated area C
Disconnect, it is insulated from each other, it is ensured that the independent partitions of liquid crystal slit grating 2, drive signal output end individually controls each isolated area
Interior first electrode 22 applies driving voltage, not by the interference of adjacent first electrode 22.
When long side of at least two first isolated areas along first substrate 29 is set, spacer portion 24a bearing of trend hangs down
Directly in the long side of first substrate 29；When short side of at least two isolated areas along first substrate 29 is set, spacer portion 24a's prolongs
Short side of the direction perpendicular to first substrate 29, i.e. isolated area are stretched for rectangular area, and first substrate 29 is divided into by spacer portion 24a
The isolated area of regular rectangular shape, is easy to operating personnel according to use demand, rationally sets the occupied area of each isolated area,
Improve the area utilization rate of first substrate 29.
To ensure the using effect of liquid crystal slit grating 2, the first spacer portion 24a width is not more than 25um, if set
First spacer portion 24a width is excessive, then lens state will not be presented in the liquid crystal layer corresponding with the first spacer portion 24a, influence
