In the example shown in Figure 6,, on polarizer 180, attach adhesive sheet 700 by adhesive linkage 300 1 sides of mounting adhesive sheet 700 on the face that is provided with light shielding part 190 of polarizer 180.In addition, adhesive sheet 700 also can be cut then from the predetermined length of state extension that is rolled into volume and be used, and in addition, also can use the sheet that is pre-formed to single sheet.At this, be under the situation of 3～10 μ m at the thickness of light shielding part 190, the thickness of the adhesive linkage 300 of preferred adhesive sheet 700 is 15～75 μ m.On the recess between the light shielding part 190, also spread all over resin thus, thereby can make surface smoothing.
Fig. 7 is that then Fig. 6 illustrates the sectional view that attaches operation.As shown in Figure 7, attach operation also have by on diffusion barrier 710 1 sides of the adhesive sheet on the face of the light incident side that is attached at polarizer 180 700, press additional heat pressure roller 800, thereby adhesive sheet 700 is laminated to operation on the polarizer 180.In the operation shown in Figure 7, in the container of atmospheric pressure (0.1MPa), the pressure roller 800 that is heated to 80 ℃～85 ℃ is on the adhesive linkage 300 of adhesive sheet 700, the direction of arrow in the figure moves while rotating with the speed of 0.3m/min, thereby with adhesive sheet 700 laminations, interim hot sticky to polarizer 180.By carrying out lamination with warmed-up pressure roller 800, can be along the concaveconvex shape landfill adhesive linkage 300 that forms by having or not of light shielding part 190, on the whole surface of the light incident side of polarizer 180, adhesive linkage 300 is set.
In addition, preferred polarizer 180 and the applying of adhesive sheet 700 and the lamination shown in Fig. 7 that carries out simultaneously among Fig. 6.Thus can less process number.
Fig. 8 is that then Fig. 7 illustrates the sectional view that attaches operation.As shown in Figure 8, attach the operation that operation also has the diffusion barrier 710 of the adhesive sheet of having peeled off by lamination from adhesive linkage 300 700.The state that 300 one-tenth of adhesive linkages are exposed remains on polarizer 180 1 sides.
In addition,, in the embodiment shown in Fig. 8, adhesive sheet 700 is bonded in carries out lamination on the polarizer 180 then earlier at Fig. 6.Replace this mode, also can earlier adhesive sheet 700 be bonded in and carry out lamination on the image displaying part 130 then.
Fig. 9 is the sectional view of the stacked operation of explanation.In lamination procedure, the face of exiting side polarized light piece 170 1 sides of the face of adhesive linkage 300 1 sides of overlapping phases difference plate 180 and image displaying part 130 Face to face, thus adjust the location of polarizer 180 and image displaying part 130.
In addition, as shown in Figure 9, the right eye of polarizer 180 is supported on the glass substrate 183 with polarized light zone 182 with polarized light zone 181 and left eye.Because the glass substrate 183 of polarizer 180 is thicker than the exiting side glass substrate 144 of image displaying part 130, and on whole, carry out bonding to polarizer 180 and image displaying part 130, so can keep intensity, can make 144 attenuation of exiting side glass substrate simultaneously.Can pass through to shorten the image production part 160 and the right eye of polarizer 180 polarized light zone 181 and the left eye distance in polarized light zone 182 of image displaying part 130 thus, and enlarge the visual angle.For example, be under the situation of 0.7mm at the thickness of glass substrate 183, the thickness of exiting side glass substrate 144 is reached below the 0.5mm.
Figure 10 (A), (B) are the sectional views of the edge painting process in the explanation spot gluing operation.In the edge painting process, at face as the exiting side of the pair of right and left side 189 of the edge part of polarizer 180 and image displaying part 130, i.e. coating resin (bonding agent) all on the left and right sides of exiting side glass substrate 144.At this, a plurality of places on each side 189 are every the interval width coating resin according to the rules of regulation.
Thus in the edge painting process, form a plurality of bonding regions 400 that leave mutually along the pair of right and left side 189 of polarizer 180.In this case, resin for example is a uv-hardening resin, as an example, can enumerate the resin of epoxiess such as the Surii Bondo3114 of Surii Bondo company or 3114B.In addition, for example under the picture size of stereoscopic display device is 46 inches situation, in 4 places in the outside of each side 189 of each side 189 and image displaying part 130 every the interval of 80mm the coating width coating resin according to 2mm.
At this, make the shake transverse width of mating plate 170 of outgoing lateral deviation narrower, thereby make left and right sides bonding region 400 spaced apart with the left and right side of exiting side polarized light piece 170 than the transverse width of polarizer 180.In addition, in the left and right edges portion of the exiting side glass substrate 144 of the side of the glass substrate 183 of polarizer 180 and image displaying part 130, be coated with bonding region 400.Thus because be not subjected to the influence of the expansion contraction of exiting side polarized light piece 170, so can observe the stable and stereoscopic image.
Figure 11 is the sectional view of edge bonding process in the explanation spot gluing operation.In the edge bonding process,, thereby make the hardening of resin of bonding region 400 to 400 one-tenth point-like of bonding region ground irradiation ultraviolet radiation.In this case, for example ultraviolet ray of irradiation accumulation light quantity 3000mJ/cm2.The left and right edges portion of the left and right side of the glass substrate 183 of bonding thus polarizer 1 80 and the exiting side glass substrate 144 of image displaying part 130.
Figure 12 is the sectional view of explanation vacuum lamination operation.In the vacuum lamination operation, in the vacuum drying oven under reduced pressure, make polarizer 180 be positioned at the top image displaying part 130 after the above-mentioned spot gluing operation and polarizer 180 are positioned on the mounting table 610.And, in the vacuum drying oven under reduced pressure,, pressure roller 600 rotates while pushing the glass substrate 183 of polarizer 180.In this case, for example carry out 1 minute vacuumize, under the laminating temperatures of the lamination pressure of 950MPa, 80 degree, carry out the lamination of 6 fens clock times.
Lamination image displaying part 130 and polarizer 180 thus, the resin to adhesive linkage 300 and bonding region 400 outgases simultaneously.Thereby, can make the thickness of adhesive linkage 300 even, improve the flatness and the depth of parallelism of image displaying part 130 and polarizer 180.In addition, can improve the transparency and the cementability of resin.In addition, outside the pressure roller laminating method of Cai Yonging, for example can also adopt the method for carrying out lamination by dividing plate in the present embodiment.
Preferably after above-mentioned lamination, the thickness of adhesive linkage 300 is the thickness identical with light shielding part 190.In lamination, thereby pressure roller can generate zone 164 arranged side by side directions rotations with image generation zone 162 and left eye with image along right eye as shown in figure 12 carries out lamination, also can be along the direction vertical with Figure 12, thus promptly right eye generates zone 162 with image and left eye carries out lamination with vertical rotation that image generates zone 164.
After above-mentioned vacuum lamination operation, carry out hot pressing process.In this hot pressing process, in the high atmosphere of pressure ratio atmospheric pressure, image displaying part 130 and polarizer 180 are heated.Lamination pressure height in the above-mentioned vacuum lamination operation of pressure ratio of the atmosphere in preferred this heating process.As an example of the condition of this hot pressing process, be that 80 ℃ and pressure are in the container of 0.6MPa in the temperature of atmosphere, image displaying part 130 and polarizer 180 are provided with 1 hour.
Discharge because the distortion that above-mentioned vacuum lamination operation produces in image displaying part 130 and polarizer 180 by this hot pressing process.And, can will do not crushed or extrude in the vacuum pressed lamination by the bubble of the adhesive linkage 300 of Ex-all by this hot pressing process.
Figure 13 is the sectional view of whole UV bonding process of explanation.In whole UV bonding process,, make the hardening of resin of adhesive linkage 300 from adhesive linkage 300 irradiation ultraviolet radiations of polarizer 180 1 sides after to above-mentioned hot pressing process.In this case, for example shining illumination is that 180mW/cm2, accumulation light quantity are that 3000mJ/cm2, wavelength are the ultraviolet ray of 365nm.Irradiation ultraviolet radiation hardens it on the resin zone of the adhesive linkage 300 between the light shielding part 190 of polarizer 180 thus.
Also adopt well heater etc. to give adhesive linkage 300 heating from the outside, make adhesive linkage 300 through-hardenings.The resin in the zone of being shone by ultraviolet ray is also hardened, image displaying part 130 and polarizer 180 more positively can be bonded together.In addition, the heating of ultraviolet ray irradiation and employing well heater also can and be used.
By being installed on the framework 110 shown in Figure 3, top bonding image displaying part 130 and polarizer 180 make stereoscopic display device 100.At this, adopt glass transformation temperature (Tg) than the resin of the high resin of the glass transformation temperature of the resin of adhesive linkage 300 as bonding region 400.For example, with respect to adopt glass transformation temperature be resin more than 80 ℃ as the resin of bonding region 400, adopting glass transformation temperature is below 0 ℃, the resin that more particularly is-20 ℃ is as the resin of adhesive linkage 300.
Promptly, the whole operation of the temperature of the resin of bonding region 400 from the edge painting process to whole UV bonding process all below glass transformation temperature, relative therewith, the temperature of the resin of adhesive linkage 300 in attaching the whole operation of operation all than glass transformation temperature height.Therefore, during carrying out spot gluing operation, vacuum lamination operation, hot pressing process and whole UV bonding process, the resin of adhesive linkage 300 becomes gluey attitude from vitreousness, and is relative therewith, and the resin of the viscosity of the resin of bonding region 400, rigidity and adhesive linkage 300 relatively maintains vitreousness.
Thereby, in the present embodiment, shrink under the situation that forms bending even produced because of expanding on one owing to the heating in each operation after the attaching operation in image displaying part 130 and polarizer 180, another and adhesive linkage 300 also can be followed this bending.In addition, because can suppress the position deviation of image displaying part 130 and polarizer 180, so can be suppressed at the image displaying part 130 under the state that uses stereoscopic display device 100 (watching stereo-picture) and the generation of the interference of light between the polarizer 180 (for example, the pattern of Newton ring).Especially under the situation of big picture, because the bending of image displaying part 130 and polarizer 180 becomes bigger, so can obtain bigger effect for the image quality raising of stereo-picture.
And, even having on the surface of image displaying part 130 and polarizer 180 under the irregular situation of distortion and thickness, because the adhesive linkage 300 that viscosity is low is followed by distortion and the irregular form of thickness of filling up this surface, so the interval of image displaying part 130 and polarizer 180 is certain, can seamlessly fill adhesive linkage 300.Thereby, can suppress the internal reflection between image displaying part 130 and the polarizer 180, suppress the generation of crosstalk.In addition, because can suppress the deviation at the interval of image displaying part 130 and polarizer 180, can suppress the generation of color spot.Thereby the image quality that can suppress stereo-picture reduces.
And, by the glass transformation temperature that makes bonding region 400 is more than the temperature conditions of each operation after the spot gluing operation, in each operation after the spot gluing operation, even can not keep at adhesive linkage 300 under the situation of sufficient adhesion strength of the weight that is used for bearing polarizer 180, bonding region 400 is kept the sufficient adhesion strength of the weight that is used for bearing polarizer 180.Therefore polarizer 180 landing can be suppressed, thereby polarizer 180 can be suppressed with respect to the position deviation on the above-below direction of image displaying part 130 owing to deadweight.
And the glass transformation temperature that makes bonding region 400 is than the temperature height of making the imaginary environment for use in back.Thus, even under the situation of the creep that produces adhesive linkage 300 owing to the heat around under the hot environment, the heating of image displaying part 130 etc., bonding region 400 also can be kept the sufficient adhesion strength of the weight that is used for bearing polarizer 180.Therefore under imaginary environment for use, can suppress polarizer 180 landing, thereby can suppress polarizer 180 with respect to the position deviation on the above-below direction of image displaying part 130 owing to deadweight.
And in the present embodiment, according to the rules compartment is every a plurality of bonding regions 400 are set on the left and right sides of polarizer 180 and image displaying part 130.The influence of the differential contraction stress that produces in the time of can making the hardening of resin of the bonding region 400 that is sent to polarizer 180 and image displaying part 130 thus diminishes.In addition, by absorbing the distortion of the polarizer 180 that mitigation produces by this differential contraction stress by adhesive linkage 300, the influence to the contrast of image displaying part 130 can be suppressed in the Min. and (can suppress the generation of color spot).
In addition, in the present embodiment, by the left and right side 189 of bonding region 400 bonding polarizers 180 and the left and right sides portion of image displaying part 130.Thus, because bonding region 400 is set, can use the entire image zone on the outside of image-region.In addition, because after stacked operation, can be by on the bight that forms on the outgoing side of the side 189 of polarizer 180 and image displaying part 130, saving bonding agent, and the outgoing side of the side 189 of bonding polarizer 180 and image displaying part 130, so can simplify bonding operation.
And, in the present embodiment, when the exiting side glass substrate 144 of the glass substrate 183 of polarizer 180 and image displaying part 130 is bonding, bonding the right and left, as long as but can keep this bonding strength, also can be with respect to image displaying part 130 bonding both sides up and down or one side.In addition, also can make the film substrate of the glass substrate 183 of polarizer 180 for the low-thermal-expansion contraction.Thus, the weight of polarizer 180 can be suppressed, thereby landing can be prevented.In addition, the bonding of this film substrate and exiting side glass substrate 144 can be four limits, both sides or on one side bonding, but under the situation of the big film substrate of the shrinkage ratio glass baseplate of base material, and it is bonding preferably to carry out four limits.
And, in the present embodiment, bonding region 400 is set at interval with exiting side polarized light piece 170.Thus, can prevent that the influence that expansion that the heat owing to exiting side polarized light piece 170 produces is shunk from feeding through to image displaying part 130 and polarizer 180 by bonding region 400.In addition, direct bonding relative phase difference plate 180 is owing to the glass substrate 183 of less polarizer 180 and the exiting side glass substrate 144 of image displaying part 130 are shunk in the expansion that heat produces.Thereby can further suppress above-mentioned position deviation.
Figure 14 is the exploded perspective view according to other stereoscopic display device 101 of the manufacture method manufacturing of present embodiment.In the stereoscopic display device 101 shown in Figure 14, give identical Reference numeral, omit explanation the structure identical with above-mentioned stereoscopic display device 100.As shown in figure 14, stereoscopic display device 101 comprises that polarizer 185 replaces the polarizer 180 of above-mentioned stereoscopic display device 100.This polarizer 185 has right eye and uses polarized light zone 187 with polarized light zone 186 and left eye.
Here, right eye is 1/4 wavelength plate with polarized light zone 186 and left eye with polarized light zone 187, and, the mutual orthogonal of each optic axis.Right eye in this phase differential portion 185 is identical with the position and the size in polarized light zone 182 with polarized light zone 181 and left eye with right eye in the above-mentioned polarizer 180 with the position in polarized light zone 187 and size with polarized light zone 186 and left eye, generates zone 162 and left eye with the right eye of image production part 160 with image and generates the position in zone 164 and big or small corresponding with image.Thereby, under the user mode of stereoscopic display device 101, see through above-mentioned right eye at right eye with incident on the polarized light zone 186 and generate the right eye image light in zone 162 with image, simultaneously left eye with polarized light zone 187 on incident see through the left eye image light of above-mentioned left-eye image generation regional 164.
And, light shielding part 190 is set at the right eye on the relative face of polarizer 185 and image displaying part 130 on polarized light zone 186 and the border of left eye with polarized light zone 187.This light shielding part 1 90 absorbs and blocking-up should be incided with the right eye of polarizer 185 with the adjacent left eye in polarized light zone 186 with the left eye on the polarized light zone 187 with in the image light, surmounts above-mentioned border and incides this right eye with the image light on the polarized light zone 186.
And, similarly, above-mentioned light shielding part 190 absorbs and blocking-up should be incided with the left eye of polarizer 185 with the adjacent right eye in polarized light zone 187 with the right eye on the polarized light zone 186 with in the image light, surmounts above-mentioned border and incides this left eye with the image light on the polarized light zone 187.Like this, by on the above-mentioned border of polarizer 185, light shielding part 190 being set, be difficult to producing crosstalk with image light and left eye with image light from the right eye of stereoscopic display device 101 outgoing.
Polarizer 185 is reverse circularly polarized light outgoing mutually with the light of incident as the sense of rotation of polarizing axis.For example, right eye with polarized light zone 186 with the light of incident as the circularly polarized light outgoing that turns clockwise, simultaneously left eye with polarized light zone 187 with the light of incident as the circularly polarized light outgoing that is rotated counterclockwise.In addition, the arrow of the polarizer 185 of Figure 14 has represented to pass through the sense of rotation of the polarized light of this polarizer 185.It is 1/4 long wave plate of horizontal direction that right eye for example adopts optic axis with polarized light zone 186, and it is 1/4 wavelength plate of vertical direction that left eye for example adopts optic axis with polarized light zone 187.
In the stereoscopic display device 101 shown in Figure 14, identical with the situation of stereoscopic display device 100, also by adhesive linkage 300 and bonding region 400 bonding image production part 160 and polarizers 185.Thus, make adhesive linkage 300 absorb bending, the convex-concave of image displaying part 130 and polarizer 180, can suppress polarizer 180 with respect to image displaying part 130 and position deviation simultaneously.
When observation has the stereoscopic display device 101 of the polarizer 185 shown in Figure 14, observer 500 wears polarised light glasses and observes, and this polarised light glasses is in the position that is equivalent to right eye 512 1 sides and be equivalent to dispose 1/4 wavelength plate and polarized light lens respectively on the position of left eye 514 1 sides.In this polarised light glasses, the optic axis of 1/4 wavelength plate that disposes on the position of right eye 512 1 sides that are equivalent to observer 500 is a horizontal direction, and the optic axis of 1/4 wavelength plate that disposes on the position of left eye 514 1 sides that are equivalent to observer 500 is a vertical direction.And, the polarized light lens that dispose on the position of polarized light lens that dispose on the position of right eye 512 1 sides that are equivalent to observer 500 and left eye 514 1 sides that are being equivalent to observer 500 are, seeing through direction of principal axis is right bank 45 degree by observer 500, and the absorption axes direction is and the above-mentioned vertical direction of direction of principal axis that sees through.
When the incident polarization optical axis is seen as the circularly polarized light that turns clockwise by observer 500 on observer 500 right eye 512 1 sides, at this circularly polarized light is after 1/4 wavelength plate of horizontal direction is transformed into the rectilinearly polarized light of right bank 45 degree by above-mentioned optic axis, see through above-mentioned polarized light lens, observe by observer 500 right eye 512.And, when the incident polarization optical axis is seen as the circularly polarized light that is rotated counterclockwise by observer 500 on observer 500 left eye 514 1 sides, at this circularly polarized light is after 1/4 wavelength plate of vertical direction is transformed into the rectilinearly polarized light of right bank 45 degree by above-mentioned optic axis, see through above-mentioned polarized light lens, observe by observer 500 left eye 514.Like this,, observe stereoscopic display device 101, can only observe the right eye image light, can only observe the left eye image light by left eye 514 by right eye 512 by putting on above-mentioned polarised light glasses.Thereby observer 500 can be identified as stereo-picture with image light and left eye with image light with these right eyes.
Figure 15 and Figure 16 are the sectional views of vacuum laminated operation of other manufacture method of explanation present embodiment.This other manufacture method comprises vacuum laminated operation, replaces the stacked operation of Fig. 5 to the manufacture method shown in Figure 13.Give identical Reference numeral with Fig. 5 to the manufacture method shown in Figure 13 identical structure and effect for this other manufacture method, omit explanation.
As shown in figure 15, in vacuum laminated operation, exiting side polarized light piece 170 be positioned at the top with image displaying part 130 mountings to lower wall 900, adhesive linkage 300 down is installed in polarizer 180 and coils on 910.Under this state, determined the position of image displaying part 130 and polarizer 180.Lower wall 900 and last dish 910 relatively are arranged on up and down in the airtight space, on coil 910 and can contact with lower wall 900.
In this vacuum laminated operation, be separately positioned on image displaying part 130 and polarizer 180 on lower wall 900 and the last dish 910 after, making in the space that is provided with them becomes vacuum atmosphere.In this case, be 1～1000Pa in this space for example.
As shown in figure 16, make dish 910 to lower wall 900 1 side shiftings, it is bonding to carry out pressure by 300 pairs of polarizers 180 of adhesive linkage and image displaying part 130.The decrement of this operational administrative adhesive linkage 300 and compression time.In this case, for example make pressure bonding before thickness be adhesive linkage 300 compression 5～25 μ m of 35 μ m.Compression time is 10～90 seconds.
Because by the vacuum laminated operation of top present embodiment, can prevent between adhesive linkage 300 and image displaying part 130, to sneak into bubble in the stacked operation, so need be not remove the vacuum lamination operation that bubble is a purpose.Thereupon because in the vacuum lamination operation, do not need heating, so can not produce the polarizer 180 that produces owing to this heating position deviation with respect to image displaying part 130.
Figure 17 is the sectional view of whole painting process in other manufacture method of explanation present embodiment.This other manufacture method comprises whole painting process, replaces the attaching operation of Fig. 5 in the manufacture method shown in Figure 13.Give identical reference marks with Fig. 5 to the manufacture method shown in Figure 13 identical structure and effect for this other manufacture method, omit explanation.
As shown in figure 17, in whole painting process, coating resin on the face of the exiting side of the exiting side polarized light piece 170 of image displaying part 130 forms adhesive linkage 300.Here, at least the right eye of image displaying part 130 generate with image zone 162 and left eye generate zone 164 and polarizer 180 with image right eye with polarized light zone 181 and the left eye zone relative with polarized light regional 182 on coating resin.Replace this mode, also can be on whole of exiting side polarized light piece 170 coating resin.
The method of coating resin can adopt mold pressing coating, gravure coating etc.In this whole painting process, adhesive linkage 300 presclerotic thickness can be identical with the thickness of light shielding part 190, also can be thinner than it.In this whole painting process, adhesive linkage 300 presclerotic thickness can suitably be set according to the area of the peristome between the light shielding part 190 and the thickness of light shielding part 190 etc.
The resin that adopts in this whole painting process preferably when hardening by ultraviolet ray, also can harden by heat.As by ultraviolet ray and the two resin that hardens of heat, can use to have the functional group that unsaturated double-bond is arranged and the resin of epoxy radicals on side chain.And, also can mix resin that coating hardens by ultraviolet ray and the resin that hardens by heat.
In this case, as the resin that hardens by ultraviolet ray, can use ultraviolet hardening resins such as amino acrylates, unsaturated polyester (UP) acrylate.And, as the resin that hardens by heat, can use unsaturated polyester resin, dially phthalate resin, urethane resin etc.And the viscosity of preferred above-mentioned resin arrives 1000cps for 500cps down at normal temperature (25 ℃).Above-mentioned viscosity ratio 500cps hour, the resin of coating can flow out.On the other hand, viscosity is during greater than 1000cps, and resin is difficult to enter between the light shielding part 190, and resin can not spread all over corner.
Figure 18 is the sectional view of the stacked operation of explanation.In stacked operation, on the face of the formation adhesive linkage 300 of image displaying part 130, the face of the formation light shielding part 190 of overlapping in opposite directions mounting polarizer 180.By under the state of mounting polarizer 180 on the image displaying part 130, image displaying part 130 and polarizer 180 are arranged in the vacuum drying oven, this vacuum drying oven is reduced pressure, carry out the degassing process that resin is outgased.In degassing process, also can outgas to resin by applying ultrasonic vibration for image displaying part 130 and polarizer 1 80.
Figure 19 is the sectional view of explanation lamination.In lamination, make polarizer 180 upwards, image displaying part 130 after the above-mentioned mounting operation and polarizer 180 are positioned on the mounting table 610.And, while rotate, come lamination image displaying part 130 and polarizer 180 by the glass substrate 183 that makes pressure roller 600 push polarizer 180.Make the thickness of adhesive linkage 300 even thus, can improve the flatness and the depth of parallelism of image displaying part 130 and polarizer 180.
Preferably after above-mentioned lamination, the thickness of adhesive linkage 300 is the thickness identical with light shielding part 190.In lamination, thereby pressure roller can generate zone 164 arranged side by side directions rotations with image generation zone 162 and left eye with image along right eye as shown in figure 19 carries out lamination, also can be along the direction vertical with Figure 19, thus promptly right eye generates zone 162 with image and left eye carries out lamination with vertical rotation that image generates zone 164.
And, after above-mentioned lamination, also can position image displaying part 130 and polarizer 180.In this case, can easily position as spacer by mixed silica class filler in adhesive linkage 300.In addition, also can carry out whole painting process, mounting operation and lamination in the vacuum drying oven under reduced pressure.Can make the better effects if of the degassing thus, thereby boost productivity.
Adopt embodiment that the present invention has been described above, but technical scope of the present invention does not limit in the scope of record in the above-described embodiment.It will be apparent for a person skilled in the art that and to carry out various changes and improvement to above-mentioned embodiment.The accessory rights claimed range is put down in writing as can be known, and the embodiment that carries out this change or improvement is also contained in the technical scope of the present invention.For example, in the present embodiment, light shielding part 190 is set on polarized light zone 181 and the boundary portion of left eye, still also can prevents from also light shielding part 190 can be set under the situation of crosstalk in that light shielding part 190 is not set with polarized light zone 182 at right eye.In this case, by omitting light shielding part 190, can further enlarge the visual angle.
