Answer the alignment direction in region identical, red sub-pixel is opposite with the alignment direction of green sub-pixels, blue subpixels corresponding region.
When carrying out orientation to the irradiating ultraviolet light of the first both alignment layers 3, blocked first by mask plate in each first area A
The region of corresponding Part I sub-pixel, first orientation is carried out to area illumination corresponding to remaining Part II sub-pixel；So
The region corresponding to mask plate blocks each first area A Part II sub-pixel afterwards, to corresponding Part I sub-pixel
Area illumination carries out orientation again, wherein, alignment direction is opposite with first alignment direction again for this.For example, first block the firstth area
Sub-pixel R regions in the A of domain, orientation is carried out to other sub-pixel G, B region irradiating ultraviolet lights in the A of first area, so
After block sub-pixel G, B regions in the A of first area, sub-pixel R regions irradiating ultraviolet light in the A of first area is carried out
The orientation of opposite direction.
S03, second substrate 2 is provided, and be formed on the second both alignment layers 4, wherein, second substrate 2 is divided into multiple
First area A second area B is corresponded to respectively.
S04, orientation is carried out to the irradiating ultraviolet light of the second both alignment layers 4 so that the second area of first area A and therewith face

Direction is as shown in Figure 2,3 towards right direction), then block the pixel cell (R1 of the lower row in second area Ba、G1a、B1a)、
(R2a、G2a、B2a)、(R3a、G3a、B3a)、(R4a、G4a、B4a) corresponding to region, to the pixel cell (R1 of upper rowb、G1b、
B1b)、(R2b、G2b、B2b)、(R3b、G3b、B3b)、(R4b、G4b、B4b) corresponding to area illumination ultraviolet light carry out opposite direction
Orientation (alignment direction is as shown in Figure 2,3 towards left direction).
S05, on second substrate 2 instill liquid crystal 5, and with first substrate 1 group stand, produce liquid crystal cell.
It should be noted that two pixel cells are provided with each first area A of the present embodiment, in the A of first area, often
Individual pixel cell by the different sub-pixel group of multiple colors into, and one of pixel cell each sub-pixel difference
With each sub-pixel face of one other pixel unit.The face of the sub-pixel of two pixel cells specifically in the A of first area
Color order of placement is identical, and the sub-pixel of the one of pixel cell picture with the respective color of one other pixel unit respectively
Plain face.So that along the length direction of display panel, between the sub-pixel of every two row same color between be separated with two sub-pixels, phase
In two adjacent viewing area C, the sub-pixel of same color has consistent orientation.
Because the sub-pixel of the same color on the first substrate of the pixel cell with array of the present invention corresponds to area
The alignment direction of the liquid crystal molecule in domain is identical so that the sub-pixel of same color can obtain identical penetrance, solve
The display difference of the brightness unevenness of the clathrate currently encountered, improves display image quality.
Described above is only the embodiment of the application, it is noted that for the ordinary skill people of the art
For member, on the premise of the application principle is not departed from, some improvements and modifications can also be made, these improvements and modifications also should
