To) on positioned, fixed pedestal 20 is also positioned on the direction (horizontal direction) vertical with gravity direction G.By being somebody's turn to do
The positioning of horizontal direction, display component 10 and fixed pedestal 20 determine opposite position in the both sides of short transverse and horizontal direction
It sets.
As shown in figs. 4 and 5, in the state that display component 10 and fixed pedestal 20 are located in fixture 40, display group
The surface of the protrusion 30 at the fixation back side 12 and fixed pedestal 20 of part 10 is adhesively fixed between face 31 separates on gravity direction
1 ground gap δ faces.Gap delta 1 in face of being spaced in the range for being set in 0.3~2.0mm in design value, be preferably set to 0.5~
The range of 1.5mm.
In Fig. 4 as shown by the arrows, bonding agent supply hole of the bonding agent 35a of liquid before curing to protrusion 30
Supply in 32.Bonding agent 35a is under gravity from bonding agent supply hole 32 towards the fixed back side 12 and the face 31 that is adhesively fixed
Gap delta 1 flow, and pass through the wettability on the surface at the fixed back side 12 and the surface in the face 31 that is adhesively fixed and bonding agent 35a
And capillarity spreads to the inside at the fixed back side 12 and the gap delta 1 in the face 31 that is adhesively fixed and fills to the face of being adhesively fixed
The whole region on 31 surface.As shown in figure 5, edge part of the bonding agent 35a spread in gap delta 1 in the face of being adhesively fixed 31
At 31a, liquid surface 35b is stopped under the action of surface tension, and bonding agent 35a will not be from the edge part in the face of being adhesively fixed 31
31a is flowed out outward and is spread.
There is assembling tolerance in display component 10, has manufacturing tolerance in keeping bracket 11, and in fixed pedestal 20
There is also manufacturing tolerances.Therefore, in each protrusion 30 for being set to multiple positions, it not can avoid at the fixed back side 12 and glue
Connect generating deviation in interval and capable of filling to the bonding agent 35a of the inside of gap delta 1 for the gap delta 1 of stationary plane 31
Liquid measure in also generate deviation.But the deviation can be carried out by the surplus of the bonding agent 35a of the inside of bonding agent supply hole 32
It adjusts.That is, bonding agent 35a is not pressurizeed but is arrived under the influence of gravity the inside of bonding agent supply hole 32, from
And even if there are deviations in interval in gap delta 1, it so that bonding agent 35a is spread the whole region of gap delta 1, and
Due to not pressurizeing, the liquid surface 35b of bonding agent 35a can be made to rest on the edge part 31a in the face of being adhesively fixed 31
Place prevents bonding agent 35a from flowing out from the face of being adhesively fixed 31 to outside.
After being filled into bonding agent 35a in whole gap deltas 1 set on multiple positions, make to be bonded by heating process
Agent 35a solidification, forms adhesive layer 35.The adhesive layer 35 that display component 10 passes through the inside of the gap delta 1 set on multiple positions
Bonding force be fixed on fixed pedestal 20.
As shown in figure 4, in the manufacturing method of display device 1, with (15a before cover plate 15) before display component 10
On the basis of fixed pedestal 20 is positioned.At this point, keeping the assembling of the dimensional tolerance when manufacture of bracket 11, display component 10 public
Difference and the manufacturing tolerance of fixed pedestal 20 are filled in be adhesively fixed face 31 and the fixed back side 12 that multiple positions are arranged in
The difference of the thickness of the adhesive layer 35 of gap delta 1 absorbs.It therefore, can be by cover plate 15 in display component 10 after assembling
Before the flatness of 15a maintain always higher, by improving the flatness of cover plate 15, can reduce to display unit 16
Deformation, and can make to show uneven reduction.
In addition, the range of 0.3~2.0mm is divided between the facing of the gap delta 1 in be adhesively fixed face 31 and the fixed back side 12, it is excellent
The range of 0.5~1.5mm is selected, design value is, for example, 1mm, and in face of being spaced the pole compared with the width dimensions in the face of being adhesively fixed 31
It is thin.Therefore, adhesive layer 35 thickness direction shrinkage stress very little, even if the thickness of the adhesive layer 35 in each gap delta 1
It spends size and generates deviation, the deviation of the shrinkage stress of the thickness direction of the adhesive layer 35 of each gap delta 1 at multiple positions is also very
It is small.
Since diffusion area of the adhesive layer 35 on the face of being adhesively fixed 31 is larger, the face direction of adhesive layer 35
Shrinkage stress becomes larger compared with the shrinkage stress of thickness direction.But pass through the whole region on the surface in the face of being adhesively fixed 31
It is middle to form adhesive layer 35 to the edge part in the face of being adhesively fixed 31, and formed in a manner of not overflowed outward from edge part,
It is bonding with the adhesive layer 35 of fixed pedestal 20 that bonding display component 10 can be managed according to the area in the face of being adhesively fixed 31
Area.Therefore, it by combining the rigidity for keeping bracket 11 etc. most preferably to set the quantity and area in the face 31 that is adhesively fixed, can keep away
Exempt to act on excessive shrinkage stress from adhesive layer 35 to display component 10, can also make the face of each gap delta 1 at multiple positions
The deviation of the shrinkage stress in direction is reduced.
In the display device 1, due to can extremely reduce from the adhesive layer 35 at multiple positions to keeping bracket 11 to apply
The stress added, therefore display unevenness, the i.e. black unevenness of the display picture based on display unit 16 can be made to reduce.Here black
Color is not the value of " minimum value of brightness " in the display picture by color liquid crystal display unit divided by " maximum value of brightness "
(" minimum value of brightness "/" maximum value of brightness " × 100 (%)), if black unevenness is reduced, described value becomes larger.
In order to inhibit the deviation of the stress as caused by the adhesive layer 35 at multiple positions, the preferably all of face 31 that is adhesively fixed
Area equation.Alternatively, it is preferred that the area equation in multiple any number of faces 31 that are adhesively fixed being adhesively fixed in face 31, such as half
The area equation in above face 31 that is adhesively fixed of number.By that will keep the size at the fixation back side 12 of bracket 11, keep bracket 11
Rigidity etc. design the area in each face 31 that is adhesively fixed with taking into account, can accurately manage based on adhesive layer 35
Bond area.For example, less than half of the area at the preferably fixed back side 12 of the total of the area in whole faces 31 that is adhesively fixed.
Also, the area in each face 31 that is adhesively fixed is preferably 1/10 or less the area at the fixed back side 12.In addition, the face 31 that is adhesively fixed
Mutual interval preferably separate 3 times or more of width dimensions of the face of being adhesively fixed 31.
As shown in figure 3, the flat shape in each face 31 that is adhesively fixed is circular, it is solid that bonding agent supply hole 32 is located at bonding
Determine the center (center of fiqure) in face 31.If the face 31 that is adhesively fixed is circular, the diffusion shape of adhesive layer 35 is also circular,
The shrinkage stress of the adhesive layer 35 generated on the direction of face becomes isotropism on the basis of the center in the face of being adhesively fixed 31.Cause
This, the stress that can limit the direction being biased to from each adhesive layer 35 to the fixed back side 12 plays a role.In addition, by that will glue
Connect the center (center of fiqure) that the face of being adhesively fixed 31 is arranged in agent supply hole 32, enable to bonding agent supply hole 32 supply bonding agent
Enough edge part 31a that the face 31 that is adhesively fixed is reached with the identical time can be carried on the back to the face of being adhesively fixed 31 with fixed to exhaustive
Bonding agent 35a is supplied in the gap delta 1 in face 12.
The variation of the flat shape in the face of being adhesively fixed is shown in FIG. 6.Be adhesively fixed face 131a shown in Fig. 6 (A)
For oblong or ellipse.The face 131b that is adhesively fixed shown in Fig. 6 (B) is rectangular-shaped, but the edge part in corner is convex curve.Figure
The face 131c that is adhesively fixed shown in 6 (C) is the cut-off shape of round a part.Due to being at least one of edge part
