The explanatory diagram of the manufacture method of Fig. 4～Figure 11 A and optical display means that Figure 11 B is present embodiment.In this enforcement
In the manufacture method of the optical display means of mode, according to reference position and the reference position of optical component 1 of liquid crystal panel P
Relative position fit liquid crystal panel P and optical component 1.
(detection of the pixel column at the center of viewing area P4)
As the reference position of liquid crystal panel P, use the pixel column at the center of viewing area P4.
Such as, as shown in Figure 4, the periphery in the multiple camera head (not shown) corner to being set in liquid crystal panel P is used
Camera watch region PA shoot.The image imaged comprises alignment mark Am.The view data quilt of the image that shooting is arrived
Input to arithmetic unit, take the circumstances into consideration to implement the image procossing of prominent alignment mark Am.Detect fiducial mark according to this view data

Thereafter, utilize line segment connected to each other for the coordinate of the alignment mark Am detected, calculate 4 alignment mark Am's
Center PC1 or on the width of liquid crystal panel P relative to center PC2, PC3 of a pair alignment mark Am.
The position of the pixel column at the center of viewing area P4 is detected according to these positions.
Furthermore, according to the difference of the setting position of the viewing area P4 outer shape relative to liquid crystal panel P, according to alignment
The coordinate of labelling Am and the center PC1 that obtains or center PC2, PC3 are sometimes and in non-display area P4
Heart position etc..In this case, according to the design load of liquid crystal panel P, by real center and the center calculated
The departure of PC1 or center PC2, PC3 is redefined for compensation dosage, takes the circumstances into consideration the above-mentioned value that calculates is compensated and added
To use.
(detection of the center of optical component 1)
As the reference position of optical component 1, use the 1st district of the central authorities being positioned at width of patterning phase separation layer 3
Territory.
By the research of present inventor et al., for optical component 1, if using with several as liquid crystal panel P
The position what mode calculates, as center, the most probably can reduce display quality.Its reason is as follows.
First, in the 3D liquid crystal indicator of FPR mode, it is necessary to pattern the 1st region and the 2nd of phase separation layer 3
The pixel column state one to one laminating optical component of region and liquid crystal panel and liquid crystal panel.Its reason is, if to 1
Individual pixel column overlaps the 1st region and the 2nd region, then can cause crosstalk.
On the other hand, in optical component 1, the limit of the length direction of optical component 1 and the 1st region, the extension in the 2nd region
Direction is sometimes and not parallel.
Such as, optical component 1 is to manufacture in a large number in reel-to-reel mode sometimes.Specifically, at the table of film coiled material of banding
Face forms light orientation material layer, and this film coiled material is carried out roll-type conveyance, while light orientation material layer is exposed on
2 kinds of polarized light alternately arranged on the direction that conveyance direction is intersected, are consequently formed 2 kinds of polarisation figures corresponding to 2 kinds of polarized light
Case (the 1st region, the 2nd region), thus make the coiled material of optical component.Then, by suitably cutting this coiled material system
Make optical component.
But, in this reel-to-reel mode, there is the situation that film coiled material wriggles in roll-type transports.Therefore, to wriggling
The 1st region or the 2nd region that the film coiled material of Yan exposes and formed there is also situation about being formed deviously.In this case, light
Learn limit and the 1st region of the length direction of component 1 or the bearing of trend in the 2nd region not parallel.
Additionally, there are the precision of the machining implemented because of the shape according to liquid crystal panel P and cause the length of optical component 1
The limit in degree direction and the 1st region or the uneven situation of bearing of trend in the 2nd region.
For those reasons, the position calculated in geometry mode in the shape according to optical component 1, pattern phase contrast
1st region and the 2nd region of layer 3 not necessarily can be overlapping with pixel column correspondingly.
For the above reasons, need following technology: in the case of optical component 1 is conformed to liquid crystal panel P, detect light
Learn the polarisation pattern of the patterning phase separation layer 3 of the center position of component 1, so that this polarisation pattern is with liquid crystal panel P's
The corresponding mode of pixel column is fitted.
About patterning the 1st region of phase separation layer 3 of center position and the 2nd region of optical component 1, it is to utilize the
The difference of the optical characteristics in 1 region and the 2nd region, makes polarized light penetrate and shoots, and uses the figure photographed
As carrying out optical detection.
But, owing to optical component 1 has polarization element layer, therefore light transmittance is relatively low, and the image photographed is the darkest, and
And, the birefringence of the protecting film Pf being attached to the surface of optical component 1 is different in face, so the solution of shooting image
Analysis more difficulty.
Therefore, in the present embodiment, the end side of width and another side at optical component 1 detect the 1st respectively
The border (detection operation) in region and the 2nd region, the position on the border detected according at one end side and another side is come really
Surely the 1st region (determining operation) of the central authorities being positioned at width of patterning phase separation layer 3.
Below, sequentially illustrate.
(detection operation)
As it is shown in figure 5, use multiple camera head (not shown), the length direction of optical component 1 both ends (with
Symbol 13,14 represents) and central part, one end 11, the other end 12 to the width being set in optical component 1 respectively
And camera watch region PA1～PA9 of central authorities shoots.About each camera watch region, it is set in the length direction of optical component 1

Territory 3Rb be from the other end 12 of optical component 1 which the 1st region, the 2nd region 3Lb from optical component 1
Which the 2nd this situation of region of the other end 12 is known.
About boundary B a, such as, can come by the image binaryzation that will photograph and by the most black boundary member smoothing in addition
Detection.This is also the same for the Bb of border.
So, by detection boundary B a, Bb, and the position detection after carrying out according to boundary B a detected, Bb,
No matter the outer shape of optical component 1, all can the position of the polarisation pattern of check pattern phase separation layer 3 exactly.
(determining operation: the determination in the 1st region of central authorities)
Then, boundary B a that detects according at one end 11 sides and the other end 12 side, the position of Bb, calculate patterning phase
The position of the central authorities on the width of potential difference layer 3.In figure 6, the position of the central authorities calculated is represented with symbol Bx.In
In the camera watch region PA3 of the central authorities that the position Bx of centre is included in the width being set in optical component 1.
Herein, so-called " central authorities on the width of patterning phase separation layer 3 ", refer in patterning phase separation layer 3
The central authorities of the width in part the most overlapping with the viewing area P4 of liquid crystal panel P.In the following description,
Part the most overlapping with the viewing area P4 of liquid crystal panel P in patterning phase separation layer 3 is referred to as " effective district
Territory ".
Such as, in optical component 1, institute in the remaining area of the end of the side, one end 11 from boundary B a to effective coverage
The remaining area of the end of the 1st region of configuration and the quantity in the 2nd region and the other end 12 side from boundary B b to effective coverage
The 1st region configured in territory and the quantity in the 2nd region different in the case of, it is considered to configured in these remaining areas
1st region and the quantity in the 2nd region and calculate the position Bx of central authorities.
Then, according to the image photographed at camera watch region PA3, detection overlaps in the 1st district of central position Bx
Territory 3Rc, determines the 1st region 3Rc of the central authorities of effective coverage.
In the image photographed, different with the color in the 2nd region or brightness owing to observing the 1st region, therefore can district
Divide the 1st region and the 2nd region.But, because of the birefringence of protecting film, following phenomenon can be produced, i.e. in a certain region
Inside observe that the 2nd region is brighter than the 1st region comparatively speaking, and in other regions, observe that the 1st region is comparatively speaking than
2 regions are bright, thus precision probably can be occurred to reduce when detecting based on shooting image.
But, as it has been described above, by the center predicting effective coverage according to boundary B a, Bb, and will be arranged in pre-
The 1st region that location is put is defined as the 1st region of the central authorities of effective coverage, it may be determined that the 1st region of the central authorities of effective coverage
Without being affected by the observed result of shooting image.
(determine operation: the detection of Central Line)
Then, according to the image photographed at camera watch region PA3, multiple coordinate is utilized to seek the 1st region 3Rc with approximate way

Distance W between boundary B c of the width of 3Rc, Bd.
Furthermore, in fig. 7, for convenience, it is to represent boundary B c, Bd with straight line, but in shooting image, border
Bc, Bd non-rectilinear.Therefore, the value of distance W gone out at multiple Site Determinations is different.Additionally, also have some figure
Boundary B c, the situation at the indefinite position of Bd is there is, at this position, it is impossible to measure distance W in Xiang.
Therefore, set threshold value (the 1st threshold value) for the quantity of the measuring point that can be effectively measured, to can effectively enter
The quantity of the measuring point that row measures and threshold value compare (step S2).
In the case of the measuring point that can be effectively measured is more than the 1st threshold value, count in the mensuration that can be effectively measured
Go out the coordinate (step S3) of the center D of width, approximate the 1st region 3Rc according to the coordinate of multiple center D
The centrage C1 (step S4) of width.As approximation, generally known statistical method can be used, such as,
The approximation method seeking regression straight line (near linear) using method of least square can be enumerated.Furthermore, about being set as the 1st threshold
Value, the lower limit of measuring point quantity that can effectively be measured, can set as one sees fit according to the specification of patterning phase separation layer 3.

Under, can carry out judging (step S5) according to threshold value set in advance (the 2nd threshold value), delete separated by a distance more than the 2nd
The determination data (step S7) of the measuring point (some D1 and some D2) of threshold value, uses remaining after removing a D1 and some D2
Remaining point carrys out approximated centerlines again.Thereafter, the quantity of remaining measuring point after the measuring point away from centrage C1 being removed
Compare (step S2) with above-mentioned 1st threshold value, carry out the judgement of process thereafter.Herein, about being set as the 2nd threshold
The upper limit separated by a distance that be worth, between center, as the situation of above-mentioned 1st threshold value, can be according to patterning phase contrast
The specification of layer 3 sets as one sees fit.
On the other hand, in the case of not measuring point away from centrage C1, according to for center D relative in
Heart line C1 separated by a distance and threshold value set in advance (the 3rd threshold value) carrys out the deviation (step S6) of assessment centers position D.
3rd threshold ratio the 2nd threshold value is little.In figure 7b, the 3rd threshold value is represented with symbol M.Deviation at center D is in
In the case of in the range of prescribed threshold, the centrage C1 obtained is defined as the centrage of the 1st region 3Rc.Additionally,
About being set as the 3rd threshold value, the upper limit separated by a distance between center, with above-mentioned 1st, the situation one of the 2nd threshold value
Sample, can set as one sees fit according to the specification of patterning phase separation layer 3.
In the case of learning that the measuring point that can be effectively measured does not reaches threshold value by the judgement of step S2, and by step
The judgement of rapid S6 is learnt and is existed and in the case of the center D being more than the 3rd threshold value separated by a distance of centrage C1, respectively
