Below, with reference to Fig. 6 A, Fig. 6 B, sheet shaped piece FXm is described relative to an example of the defining method of the bonding position (relative bonding position) of liquid crystal panel P.
First, as shown in Figure 6A, the Width of optical sheet FX sets multiple checkpoint CP, detect in the direction of CP place to the optical axis of optical sheet FX, each checkpoint.When to detect moment of optical axis can be the manufacture of coiled strip roller R1, also can be to unreeling out optical sheet FX from coiled strip roller R1 carrying out hemisect during.The data of the optical axis direction of optical sheet FX and the position (position of the length direction of optical sheet FX and the position of Width) of optical sheet FX are stored in explicitly and omit in illustrated storage part.
Control part 40 obtains the data (the inspection data of distribution in the face of optical axis) of the optical axis of each checkpoint CP from storage part, and detects the direction of the average optical axis of the optical sheet FX (region by incision line CL divides) cutting out the part of sheet shaped piece FXm.
Such as, as shown in Figure 6B, the direction of optical axis and the edge line EL angulation (drift angle) of optical sheet FX is detected for each checkpoint CP, maximum angle (sail angle) in drift angle is being denoted as θ max, when minimum angle (angle of minimum deviation) is denoted as θ min, detect that the mean value θ mid (=(θ max+ θ min)/2) of sail angle θ max and angle of minimum deviation θ min is using as average drift angle.Then, detect relative to the edge line EL of optical sheet FX to be that the direction of average bias angle theta mid is using the direction of the average optical axis as optical sheet FX.It should be noted that, such as, the edge line EL relative to optical sheet FX is just being set to the direction of anticlockwise, dextrorotary direction is set to bear calculates drift angle.
Then, be the mode of desired angle relative to the long limit of the viewing area P4 of liquid crystal panel P or minor face with the direction of the average optical axis of the optical sheet FX detected by above-mentioned method, determine the bonding position (relative bonding position) of sheet shaped piece FXm relative to liquid crystal panel P.Such as, when to become relative to the long limit of viewing area P4 or minor face according to design specification by the direction setting of the optical axis of optical component F1X be the direction of 90 °, be the mode of 90 ° relative to the long limit of viewing area P4 or minor face with the direction of the average optical axis of optical sheet FX, sheet shaped piece FXm is fitted on liquid crystal panel P.
The first above-mentioned shearing device 31 and the second shearing device 32 detect the outer peripheral edges of the viewing area P4 of liquid crystal panel P by testing agencies such as cameras, and along the outer peripheral edges of viewing area P4, the sheet shaped piece FXm be fitted on liquid crystal panel P are cut into endless.Taken by the end to liquid crystal panel P, the outer most edge etc. of black matrix (Black Matrix) that is arranged on the alignment mark on liquid crystal panel P or is arranged in the P4 of viewing area, detect the outer peripheral edges of viewing area P4 thus.Have the frame portion G (with reference to Fig. 3) of Rack in the arranged outside of viewing area P4, this frame portion G is for configuring the sealant etc. the first substrate P1 and second substrate P2 that form liquid crystal panel P engaged.The cut-out (line of cut: WCL) of the sheet shaped piece FXm based on the first shearing device 31 and the second shearing device 32 is carried out in the width of this frame portion G.In the present embodiment, in the width of this frame portion G, carry out the cut based on each shearing device 31, shearing device 32.
As shown in Figure 8, when carrying out cut to resinous optical sheet FZ separately, it cuts off and holds t to expand because of thermal deformation or to rise and fall sometimes.Therefore, when the optical sheet FZ after cut is fitted in optical display components, easily make the problem that the laminatings such as optical sheet FZ generation air is mixed into, deformation are bad.
On the other hand, as shown in Figure 7, carry out in the present embodiment of cut to sheet shaped piece FXm being fitted in after on liquid crystal panel P by the sheet shaped piece cut out from optical sheet FX FXm, the cut-out end t of sheet shaped piece FXm is supported by the glass surface of liquid crystal panel P.Therefore, the expansion of the cut-out end t of sheet shaped piece FXm or fluctuating etc. can not be produced, and that therefore laminating also can not occur is bad owing to carrying out cut after sheet shaped piece FXm is fitted in liquid crystal panel P.
The amplitude of fluctuation (tolerance) of the cutting line of laser machine is less than the amplitude of fluctuation (tolerance) of cutoff tool.Therefore in the present embodiment, cut off compared with the situation of optical sheet FX with use cutoff tool, the width of frame portion G can be reduced, thus can realize liquid crystal panel P miniaturization and (or) maximization of viewing area P4.Therefore, this is effective for the application to the high function mancarried device such as required expansion display frame in recent years as smart mobile phone, tablet terminal under the size-constrained prerequisite of housing.
