It is preferred that, such as shown in Fig. 2 (a), color membrane substrates are divided into multiple pixel cells 20, and each pixel cell 20 includes the
One sub-pixel 201, the second sub-pixel 202 and the 3rd sub-pixel 203；First alignment mark pattern 101 is located at the first sub-pixel 201
Interior, the second alignment mark pattern 102 is located in the second sub-pixel 202, the 3rd alignment mark pattern 103 is located at the 3rd sub-pixel
In 203.
Wherein, the first alignment mark pattern 101, the second alignment mark pattern 102 and the 3rd alignment mark pattern 103 can
In same pixel cell, can also be located in different pixel cells.In addition, for alignment mark pattern in sub-pixel
In position without limit, can be located at sub-pixel in optional position.
Herein, in order to not influence the light transmittance of sub-pixel, thus preferred, the size of alignment mark pattern should in sub-pixel
Account for less than the 1/3 of sub-pixel size.
The utility model embodiment, by the first alignment mark pattern 101, the second alignment mark pattern 102 and the 3rd contraposition
Indicia patterns 103 are separately positioned in the first sub-pixel 201, in the second sub-pixel 202 and in the 3rd sub-pixel 203, relative to
Alignment mark pattern is arranged on Dummy areas in the prior art, because the alignment mark pattern of the utility model embodiment will not
The Dummy areas of color membrane substrates are taken, thus add the utilization rate of color membrane substrates.Furthermore, it is possible to solve large scale splicing exposure
In the case that product and color membrane substrates utilization rate are higher, it is impossible to the problem of alignment mark pattern is set.
It is preferred that, as shown in figure 3, there is color membrane substrates the pixel for being used to limit sub-pixel to limit area；Color membrane substrates are also wrapped
The light-shielding pattern 30 limited positioned at pixel in area is included, alignment mark pattern is with light-shielding pattern 30 with the same material of layer.
Wherein, for light-shielding pattern 30 material without limit, for example can be black resin.
Herein, light-shielding pattern 30 and the same layer of alignment mark pattern, that is, refer to light-shielding pattern 30 and alignment mark pattern is in together
On one loading end.
In addition, pixel limits area, that is, refer to the alternatively non-transparent region of color membrane substrates.
The utility model embodiment, because light-shielding pattern 30 and alignment mark pattern are with the same material of layer, thus can be in system
Make to make alignment mark pattern while light-shielding pattern 30, so as to simplify the manufacture craft of color membrane substrates.
It is preferred that, as shown in Fig. 3, Fig. 4 and Fig. 5, the sub-pixel is separated into by the alignment mark pattern in sub-pixel
(the utility model Figure of description 3, Fig. 4 and Fig. 5 are shown at least two transmission regions exemplified by being separated into two lightproof areas
Meaning).
It should be noted that the contraposition process of color membrane substrates is specifically：The detection system of exposure machine is aligned on Mask first
An alignment mark, then by the center alignment of alignment mark on the center of alignment mark on the Mask and color membrane substrates, to enter
Row contraposition.During contraposition, CCD is contrasted the image captured and the standard pattern prestored in CCD, if capture
Image and the matching degree of standard pattern or contrast that prestore less than default matching degree or contrast lower limit when, then CCD is grabbed
Take the alignment mark on color membrane substrates to fail, then need to find the alignment mark on Mask again, for example the Z axis of adjustment detection system
Position.
The utility model embodiment, if alignment mark pattern is set against light-shielding pattern 30, i.e., sub-pixel includes one
Transmission region, then when being aligned, transfer the quasi- pattern prestored in CCD, the contraposition in standard pattern and sub-pixel now
Indicia patterns are identical.Because the alignment mark pattern in sub-pixel is smaller, thus it may result in alignment mark center on Mask
It can not be alignd with alignment mark pattern center on color membrane substrates, thus can not be aligned or aligned and be inaccurate.
Based on this, if sub-pixel is separated into at least two transmission regions using alignment mark pattern, aligned
When, it is possible to use alignment mark pattern and closed hoop mark (i.e. the shape of the transmission region) progress pair of the formation of light-shielding pattern 30
Position, and the standard pattern prestored in CCD is identical with the size shape of transmission region, and when being aligned, CCD can prestore
The transmission region of image that captures of standard pattern and CCD aligned.
Example, when being aligned, the standard pattern prestored, shape such as Fig. 3 of standard pattern can be transferred from CCD
Shape shown in middle dash area, and the standard pattern progress that the transmission region of the CCD images captured and current CCD are transferred
Contrast.
Herein, it is necessary to which explanation, marks the threshold variations for being to rely on gray scale to realize because exposure machine is recognized, therefore not
Pipe is hollow mark or filled marks, as long as there is obvious grey scale change, you can accurately to recognize the margin location of mark
Put, therefore exposure machine can recognize that (i.e. alignment mark pattern is formed with light-shielding pattern 30 for the transmission region of the image that CCD is captured
Closed hoop mark), and then the standard that the exposure machine transmission region of image that can capture CCD is transferred with current CCD
Pattern is contrasted.The utility model embodiment, exposure machine is same as the prior art to the exposure process after contraposition, herein no longer
Repeat.
It is further preferred that as shown in figure 4, the alignment mark pattern in a sub-pixel includes：First sub-pattern of bar shaped
104 and protrude from the second sub-pattern 105 of the side of the first sub-pattern 104 1；The two ends of first sub-pattern 104 respectively with position
Light-shielding pattern 30 at the long side position of the sub-pixel two is connected, and sub-pixel is separated into two transmission regions；Same contraposition
The shape of each first sub-pattern 104 in indicia patterns group 10 is identical, and the shape of each second sub-pattern 105 is differed.
Wherein, in same alignment mark pattern groups 10, the second sub-pattern 105 can be located at the same of the first sub-pattern 104
Side, can also be located at the not homonymy of the first sub-pattern 104.
It should be noted that relative to the first sub-pattern 104 two ends respectively with the short side position of sub-pixel two
Light-shielding pattern 30 be connected, the utility model embodiment, the two ends of the first sub-pattern 104 respectively with positioned at the long side of sub-pixel two
Light-shielding pattern 30 at position is connected, and can so make the area of the first sub-pattern 104 occupancy sub-pixel smaller, i.e. the first subgraph
The influence of the sub- pixel transmittance rate of 104 pairs of case is smaller.Based on this, due in same alignment mark pattern groups 10, the second sub-pattern 105
Shape differ, thus when being aligned, first can judge to be specifically color membrane substrates according to the shape of the second sub-pattern 105
Which film layer corresponding alignment mark pattern.Afterwards, then from CCD the standard drawing prestored corresponding with the film layer is transferred out
Case, and the transmission region (can be any one in two transmission regions) of the standard pattern and the CCD images captured is entered
Row contrast.
Example, if the second sub-pattern 105 in the alignment mark pattern of detection system detection judges alignment mark
When pattern is the first alignment mark pattern 101, then CCD can be transferred out and the sub-pixel where the first alignment mark pattern 101
Transmission region (can be any one in two transmission regions) corresponding standard pattern is contrasted；If according to the inspection of detection system
When the second sub-pattern 105 in the alignment mark pattern gone out judges alignment mark pattern for the second alignment mark pattern 102, then
CCD can transfer out the standard pattern progress pair corresponding with the transmission region of the sub-pixel where the second alignment mark pattern 102
Than；If the second sub-pattern 105 in the alignment mark pattern of detection system detection judges that alignment mark pattern is the 3rd pair
During the indicia patterns 103 of position, then CCD can transfer out relative with the transmission region of the sub-pixel where the 3rd alignment mark pattern 103
The standard pattern answered is contrasted.
Based on above-mentioned, the sub-pixel where the first sub-pattern 104 is divided into two transmission regions by the first sub-pattern 104,
During contraposition, CCD is contrasted the transmission region for capturing image with the standard pattern that CCD prestores.If same contraposition
In indicia patterns group 10, two transmission regions, the second alignment mark pattern of the sub-pixel where the first alignment mark pattern 101
Two transmission regions of the sub-pixel where two transmission regions of the sub-pixel where 102, the 3rd alignment mark pattern 103
Size shape is differed, then judges that alignment mark pattern is specific in the second sub-pattern 105 in alignment mark pattern
Be which film layer alignment mark pattern after, CCD is required for transferring standard pattern corresponding with the film layer every time, so results in
Multiple standard patterns that prestore are needed in CCD, and when judging that the second sub-pattern 105 changes every time, CCD then needs to adjust again
Standard pattern is taken, so as to cause contraposition activity time longer.
Based on above-mentioned, the utility model embodiment is it is further preferred that as shown in Figure 4 and Figure 5, same alignment mark pattern
In sub-pixel where the alignment mark pattern of group 10, the printing opacity of the side of the second sub-pattern 105 is deviated from positioned at the first sub-pattern 104
The size shape in region is identical；Wherein, the second sub-pattern 105 in same alignment mark pattern groups 10 is located at the first sub-pattern
104 the same side.
Wherein, for the first sub-pattern 104 away from the side of the second sub-pattern 105 transmission region size shape without
Limit, be defined by the normal contrast for not influenceing CCD to capture the standard pattern that the transmission region of image and CCD prestore.
Because the first sub-pattern 104 deviates from when being shaped as rectangle of transmission region of the side of the second sub-pattern 105, now
The standard pattern that CCD prestores also is matrix, is easy to CCD to capture the standard pattern progress that the transmission region of image and CCD prestore
Contrast, thus the utility model embodiment, it is preferred that as shown in figure 5, the first sub-pattern 104 deviates from the side of the second sub-pattern 105
Transmission region be shaped as rectangle.
The utility model embodiment, due to the sub-pixel where the alignment mark pattern of same alignment mark pattern groups 10
In, it is identical away from the size shape of the transmission region of the side of the second sub-pattern 105 positioned at the first sub-pattern 104, and same contraposition
The second sub-pattern 105 in indicia patterns group 10 is located at the same side of the first sub-pattern 104, thus only needs to transfer on CCD
One standard pattern, just can be to the first alignment mark pattern 101, the second alignment mark pattern 102, the 3rd alignment mark pattern
Film layer corresponding to 103 is aligned, so as to save the time of contraposition process.
Further, in the sub-pixel on color membrane substrates where the alignment mark pattern of each alignment mark pattern groups 10,
It is identical away from the size shape of the transmission region of the side of the second sub-pattern 105 positioned at the first sub-pattern 104；Wherein, same contraposition
