It should be noted that the manufacturing method of the complex (laminated body) of the present invention may be embodied on foregoing glass piece 12
Form the process (or the process for further carrying out aforementioned surfaces processing) of the resin layer 14.
In the manufacturing method of the complex of the present invention, if (B) of Fig. 1 is illustrated conceptually by, in such original complex 10a
Sheet glass 12 on, according to the size for the complex 10 to be manufactured, shape, form the score line 18 for being cut off.As before
It is described, since original complex 10a is rectangle, score line 18 is extended in the vertical direction in paper.
Here, the score line 18 formed on sheet glass 12 is formed from 14 side of resin layer.That is, making 20 contact pressure resin of cutter
Layer 14 runs through (cut-out) resin layer 14, and score line 18 is formed on sheet glass 12.In other words, cut is formed on sheet glass 12
While line 18, the cut-out of resin layer 14 is carried out.
By being carried out at the same time the formation of the cut-out and score line 18 of resin layer 14, the side as shown in patent document 2
Cut-out and the formation of score line 18 the two processes for carrying out resin layer 14 shown in method like that, in addition, need not also carry out resin
The position pairing of the off-position of layer 14 and the forming position of score line 18.
In turn, in complex 10 obtained, the section of the section and sheet glass 12 of resin layer 14 can be made well
Unanimously (two sections can be made to be in same plane).
The formation of score line 18 can form score line according to sheet glass 12 and resin layer 14, utilization through resin layer 14
18 well known means carry out.As wherein an example, can illustrate the various cutters using resin, glass it is various
The method of cutter.
It should be noted that in the manufacturing method of the complex (laminated body) of the present invention, have on the surface of sheet glass 12
Defined resin layer 14, this will be described later.Therefore, even if score line 18 (forming position of the score line 18 of sheet glass 12)
There is the defects of more notch (chipping), can also inhibit the crackle that sheet glass 12 generates when cutting off in sheet glass 12
Interarea on propagate.Therefore, in the manufacturing method of the present invention, need not special consideration should be given to will produce notch etc. in score line 18, because
This, the formation of score line 18 can also be carried out using cheap cutter 20 etc..
For the width (size in the direction vertical with extending direction of line) of score line 18, the depth of score line 18, with
The cut-out of common sheet glass (glass plate) is same, can to suitably set according to the thickness of sheet glass 12, forming material etc.
The width and depth for cutting off sheet glass 12 by ground.
As shown in (B) of Fig. 1, formed after score line 18 on the sheet glass 12 of original complex 10a, such as (C) of Fig. 1
It is illustrated conceptually by, bends original complex 10a in a manner of applying tensile stress to the face of 14 side of resin layer of sheet glass 12.
Being as a result, starting point with score line 18 makes sheet glass 12 be broken, and cuts off original complex 10a, if (D) of Fig. 1 is illustrated conceptually by, shape
At the complex 10 with target size, shape.That is, by bending original complex in a manner of so that 14 side of resin layer is become convex
10a makes sheet glass 12 be broken, cuts off sheet glass 12, formed and answered with target size, shape to be starting point with score line 18
Zoarium 10.
Here, the manufacturing method of complex (laminated body) according to the present invention, even if in the relatively thin situation of sheet glass 12, drawing
In the case that trace line 18 is there are multiple notches, sheet glass 12 that when cut-out that can also prevent original complex 10a generates is split
Line (cracking) propagates (diffusion/development) on the interarea of sheet glass 12.
As previously mentioned, by using the complex for being formed with resin layer on sheet glass 12, can manufacture may be implemented it is thin
Membranization, lightweight, and set by the excellent electronics that can also prevent the crackle of sheet glass 12 when deformations, flexible such as be bent
It is standby.
Here, complex be typically will be bigger than target complex the cut-out of original complex and be made desirable size,
The complex of shape.As cutting-off method, there are as below methods：Resin layer is cut off, and then according to the cutting line and in sheet glass
Score line is formed on 12, and sheet glass 12 is cut off.But this method needs cutoff process twice, and in the position of off-position
It sets pairing etc. and expends energy.In addition, previous method usually also has following situations：When cutting off sheet glass 12, because drawing
Notch of trace line etc. and the crackle of sheet glass 12 that generates is propagated on the interarea of sheet glass 12, complex has splitting for sheet glass 12
Defect as line.The crackle is particularly susceptible generation when sheet glass 12 is relatively thin.
In addition, the manufacturing method as the complex with desirable shape that need not expend the energy such as position pairing
(cutting-off method) is carried out at the same time score line 18 just like shown in patent document 3, by forming score line 18 across resin layer
Form the method with the cut-out of resin layer.
However, with the cut-out of resin layer and when forming score line 18 on sheet glass 12, the formation of score line 18 needs
A degree of power, the power being applied on cutter 20 are also applied on sheet glass 12.Therefore, score line 18 will produce more lack
The defects of mouth.In previous method, when the sheet glass 12 like this with multiple notches is cut off (making its fracture), it can be lacked because of this
Mouthful the defects of and generated in sheet glass 12 compared with multiple cracks, moreover, the crackle can propagate on the inside of the interarea of sheet glass 12.It is tied
Fruit, obtained complex become the complex of defect as the crackle with sheet glass 12.The generation of such crackle is in glass
When glass piece 12 is relatively thin especially frequent occurrence.
In this regard, in the manufacturing method of the present invention, the thickness of the resin layer 14 of original complex 10a (i.e. complex 10) is 1
~100 μm, the Young's modulus away from the region at a distance from the normal direction at the interface of sheet glass 12 being 0~0.5 μm is 100MPa
More than.In turn, resin layer 14 is adhered to sheet glass 12 with the bonding force that 180 ° of peel strengths are 1N/25mm or more.
As a result, in the cut-out of original complex 10a (when with fracture of the score line 18 for the sheet glass 12 of starting point), even if
Sheet glass 12 cracks and applies stress to sheet glass 12, and the elastomeric resin of sheet glass 12 is adhered to high bonding force
Layer 14 can also prevent crack propagation caused by stress.Therefore, it is possible to inhibit the crackle that sheet glass 12 generates in sheet glass
It is propagated on 12 interarea.
In addition, by having such resin layer 14, can prevent from not needing in the position application for not forming score line 18
Stress to sheet glass 12 rupture.Therefore, the manufacturing method of complex of the invention can also form answering for the abnormity such as circle
It is fit.
Therefore, it using the manufacturing method of the complex of the present invention, can steadily manufacture with desirable size, shape
And inhibit the complex 10 (not having the complex 10 of crackle in the effective coverage of sheet glass 12) of the crackle of sheet glass 12.
In the manufacturing method of the present invention, the thickness of resin layer 14 is 1~100 μm.
When the thickness of resin layer 14 is less than 1 μm, can not obtain has the effect of resin layer 14, will produce following bad feelings
Condition etc.：On original complex 10a formed score line 18 when sheet glass 12 rupture and crack propagation, cut-out when (when fracture)
Region other than score line 18 cracks.
In addition, when the thickness of resin layer 14 is more than 100 μm, following unfavorable condition etc. will produce：It can not obtain with good
Good flexible complex 10 is unable to fully meet filming, light-weighted requirement, and the formation of score line 18 becomes difficult.
In addition, from can more appropriately inhibit the crackle of sheet glass 12, the complex with good flexibility can be obtained
10, it can suitably realize that lightweight, filming of complex etc. consider that the thickness of resin layer 14 is preferably 10~50 μ
m。
Resin layer 14 away from a distance from the normal direction at the interface of sheet glass 12 (direction vertical with interface) be 0~

14 Young's modulus ") it is 100MPa or more.
When the Young's modulus of resin layer 14 is less than 100MPa, sheet glass 12 will produce in the cut-out of original complex 10a
Crack propagation a problem that.
Consider from crackle that can more appropriately inhibit sheet glass 12 etc., the Young's modulus of resin layer 14 is preferably
1000MPa or more.
The upper limit of the Young's modulus of resin layer 14 is not limited.Here, if in view of not making flexible reduce (not make bending
Rigidity improves) etc., the Young's modulus of resin layer 14 is preferably 50000MPa hereinafter, more preferably 10000MPa or less.
The Young's modulus of resin layer 14, which utilizes, is based on JIS K 7127：1999 method measures.
In addition, when resin layer 14 (0.5 μm of region below of thickness of its 12 side of sheet glass) is made of more (n) layers, tree
The Young's modulus E (Young's modulus E) of lipid layer 14 is calculated with following formula (1).

Ik；The cross sectional moment of inertia of kth layer
k；The integer of 1~n
I；The cross sectional moment of inertia in the region of 0~0.5 μm of the thickness of 12 side of sheet glass of resin layer 14
From formula (1) it is found that even if using bonding agent by resin layer 14 be bonded on sheet glass 12 and bonding agent than tree
In the case that lipid layer 14 is also soft, as long as the thickness of adhesive layer is sufficiently thin (being, for example, 100nm or less), then the poplar of resin layer 14
Family name's modulus also can be 100MPa or more.
In the manufacturing method of the present invention, resin layer 14 with 180 ° of peel strengths be 1N/25mm or more bonding force (below
