For further setting forth the present invention, reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, its specific embodiment of cutting-off method, method, step, feature and effect thereof to the resin plate proposing according to the present invention, be described in detail as follows.
Fig. 1 (a) mean glass substrate 1 in the liquid crystal mother substrate A cutting out before unit panel, with the profile that is pasted on the Polarizer 2 above it, be wherein to take this liquid crystal mother substrate A by laser beam B from the situation cutting off preset lines S and divide the unit panel A1, the A1 that are broken into left and right as example describes.
As shown in Fig. 1 (a), to become, make to suppress to the focus P of the laser beam B of the heat damage of glass substrate 1 mode toward the defocus condition of top (or below) skew of liquid crystal mother substrate A, laser optical system (diagram is outer) is configured in to the top that cuts off preset lines S.In the situation of the present embodiment, Polarizer 2 is with formation such as PET resins, and the thickness of glass substrate 1 is 0.7mm left and right, and the thickness of Polarizer 2 is 0.2mm left and right.In addition, by the position of the focus P of the laser beam B defocusing, be also that the distance H above of focus P and Polarizer 2 is set into about 2mm.
As the laser beam B being used, be preferably and use for the good wavelength of Polarizer 2 absorption efficiencies, for example there is the CO of the wavelength of 9.4 μ m or 10.6 μ m
2laser.
And, as shown in Fig. 1 (b), make to cut off preset lines S near under the state that exposes of part, along cutting off preset lines S in its both sides or one-sided configuration is covered the shield (shading member) 3 of laser beam B.Shield 3 is to use the CO such as glass plate or pad winding (shim tape)
2the material that laser cannot see through.
For convenience of explanation, the machining state when not using shield 3 describes simply.Fig. 2 (a) and Fig. 2 (b) mean the laser beam B irradiating with defocus condition, the schematic diagram of machining state when direct irradiation is in Polarizer 2 in the situation that not using shield 3.
The position of irradiating laser beam B above Polarizer 2 and be focus P is downside comparatively, the state namely defocusing, and also beam diameter is wide compared with focus P.Therefore, light intensity distributions on Polarizer 2, as as shown in Fig. 2 (b), become that to take the optical axis center of laser beam B be peak value part, and be compared to focus P (with reference to Fig. 5 (a)), draw the form (Gaussian distribution on gentle slope) of the mountain shape of the tail-end value (tail) that periphery is gently decayed toward the outer side.Once this laser beam B is irradiated in Polarizer 2, the groove C1 forming at Polarizer 2, as shown in Fig. 2 (a) as, become the shape that makes light intensity distributions reversion.Therefore, along the section that cuts off preset lines S and divide the Polarizer 2 of having no progeny, forming the inclined plane on gentle slope, is not state preferably as the disjunction quality of Polarizer 2.Although also according to the article shape of minute having no progeny and opinion, generally speaking, this inclined plane more near vertical is more high-quality.
In the present invention, as as shown in Fig. 3 (a), by shield 3 (shading member) so that cut off state that near the part of preset lines S exposes and along cutting off preset lines S configuration, only to make the irradiation of the peak value part B1 optical axis center in light intensity distributions near in the mode of cutting off preset lines S, by other tail-end value part B2 by shield 3 blockings.The end face of shield 3 and the interval L that cuts off preset lines S, be preferably 10～200 μ m left and right, is more preferred from 20～100 μ m left and right.
By make laser beam move along cutting off preset lines S in mode described above, and at Polarizer 2 the groove C as forming as shown in Fig. 3 (b).Laser beam is only with peak value part B1 in light intensity distributions, to irradiate the cut-out preset lines S part between the shield 3,3 of left and right, and tail-end value part B2 is by shield 3 blockings.Irradiate in the laser beam that cuts off preset lines S, because being irradiates with defocus condition, therefore with as while making focus be positioned at irradiating of Polarizer 2 above as, through the higher laser beam of the peak value of the luminous intensity of optically focused, compare, luminous intensity is weakened and is some strength roughly, can suppress the heat damage to glass substrate 1.In cutting off preset lines S, irradiate the laser beam of this peak value part B1, can or degrade and form groove C by melting.
In addition, at shadow surface, the tail-end value part B2 of the light intensity distributions of laser beam is interdicted by shield 3, by luminous intensity, be that the irradiation of peak value part B1 of roughly some strength is in Polarizer 2, therefore illuminated portion complete utilization roughly uniformly light energy process uniformly (degrading or melting), and the groove C after processing forms left and right sidewall through cutting straight precipitous inclined plane as shown in Fig. 3 (c).Therefore,, while glass substrate being broken into unit panel A1, A1 in 1 minute along cut-out preset lines S in next step, the end face of Polarizer 2 forms precipitous inclined plane, can make the width L1 of tilting zone diminish.Also, according to the present invention, can suppress to form precipitous inclined plane to the heat damage of glass substrate and at Polarizer.In the past, this effect only can be reached with contrary each other condition (defocusing or optically focused), but according to the present invention, can utilize scanning once to reach the processing result that in the past cannot make the best of both worlds.
Herein, for using concrete processing example of the present invention to describe.The liquid crystal mother substrate that the thickness of slab that is 0.7mm and resinous Polarizer 2 at the thickness of slab of glass substrate 1 is 0.2mm, the shield 3 that installation thickness of slab is 0.5mm, the end face of shield 3 is set as to 50 μ m with the interval L that cuts off preset lines S, the distance H defocusing above of the focus P of laser and Polarizer 2 is set as to 2mm, and with CO
2laser cutting Polarizer 2.
Its result is to make the width L1 of tilting zone be improved to the 38 μ ms less compared with 50 μ m of target.
In addition, in order to compare, carried out the result of same Ear Mucosa Treated by He Ne Laser Irradiation shield 3 is not installed, the width L1 of tilting zone is more than 80 μ m.
Then, for the second embodiment, describe.Fig. 4 means the situation that the Polarizer 2 of the state stickup with from the end face of glass substrate 1 overhanging (overhang) is cut off.
This situation, as shown in Fig. 4 (a), the end material part 2a cutting off from Polarizer 2 will be dropped, and therefore, shield 3 is only disposed at along glass substrate 1 side of the cut-out preset lines S of the end face of glass substrate 1.Then, with above-described embodiment similarly, laser beam B is irradiated on Polarizer 2 along cutting off preset lines S with defocus condition.Accordingly, the sidewall of the groove C ' forming at Polarizer 2, as shown in Fig. 4 (b), the side that has shield 3 in mounting, peripheral part (tail-end value part) B2 in similarly calorific intensity being distributed with last embodiment is by shield 3 blockings, therefore form precipitous inclined plane, opposition side forms the inclined plane on gentle slope.Using the Polarizer of the side on the inclined plane on this gentle slope 2 as end material 2a, abandon.
Whereby, as shown in Fig. 4 (c), can make to be pasted on the cut-out end face of the Polarizer 2 of glass substrate 1, the state consistent with the end face with glass substrate 1 cuts off, and can make the width L1 of tilting zone of the cut-out end face of Polarizer 2 diminish.
Above, though be illustrated for representational embodiment of the present invention, the present invention might not be specific to the above embodiments.For example, as the resin plate that should cut off, though disclose, there is the Polarizer of the glass substrate that is pasted on display panels, even become the substrate beyond the substrate glass of bottom, for also can utilize the present invention by what bear heat damage when irradiating laser beam.In addition in the present invention, can, reaching its object, not departing from the scope of claim, suitably revise, change.
The present invention uses when the resin plate that is pasted on glass substrate to as the Polarizer of display panels cuts off.
