【０００１】
【発明の属する技術分野】
本発明は、３Ｄ映像を現出させる為の３Ｄ映像表示体の製造方法に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
従来から、例えばＵＳＰ５,３２７,２８５号に示すような３Ｄ映像装置が提案されている。この３Ｄ映像装置は図１に図示したように液晶部材51の表面に右目用映像表示部ａと左目用映像表示部ｂとが交互に並設されたフィルム52を貼り合わせたもので、該液晶部材51の発光をコントロールして所定の映像を現出させる際、右目用映像表示部ａからは右目用映像を、また、左目用映像表示部ｂからは左目用映像を現出させるものである。そして、右目用映像表示部ａからの右目用映像を構成する偏光の振動方向は左目用表示部ｂからの左目用映像を構成する偏光の振動方向に対し９０°の角度を有する偏光となるように構成されている為（二成分ｘ，ｙから成る右目用映像の例えばｘ成分は、同様に二成分ｘ，ｙから成る左目映像のｘ成分に対して１８０°（π）の位相差を有するように構成されている為)、右目用映像のみを透過する偏光板付右目用レンズと左目用映像のみを透過する偏光板付左目用レンズとから成る偏光メガネで該映像を見ると、観察者は立体映像を観念し得ることになる。
【０００３】
ところで、前記右目用映像表示部ａ及び左目用映像表示部ｂが交互に並設されたフィルム52の製造方法はこれまで前記ＵＳＰ５,３２７,２８５号のFig２に開示されているように、ＴＡＣフィルムとヨウ素処理した延伸ＰＶＡフィルムとを積層した偏光フィルムにフォトレジストをコートし、所定部分を露光後、水酸化カリウム溶液で処理して延伸ＰＶＡフィルムが有する特定の波長域の光の振動方向を直線偏光状態のまま回転し得る性質（位相差機能）を消失させるという方法で製造されている。しかし、この方法はフォトレジストのコート後、露光させ、更に、水酸化カリウム溶液で処理しなければならず、非常に煩雑な製造方法である。ＵＳＰ５,３２７,２８５号には上記のような化学的処理によりフィルム52を製造する数種の方法、及び物理的処理によりフィルム52を製造する方法等が開示されているが、いずれも同様に煩雑な製造方法である。
【０００４】
本発明は非常に簡易にして量産性に秀れた右目用映像表示部ａ及び左目用映像表示部ｂが混在するフィルムを及びその製造方法を提供するものである。
【０００５】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００６】
右目用映像表示部ａと左目用映像表示部ｂとが混在した３Ｄ映像を現出させる為の３Ｄ映像表示体の製造方法であって、透明な支持材１上に接着剤２を介して位相差機能を有する延伸ＰＶＡフィルム７を設け、続いて、この延伸ＰＶＡフィルム７の所定位置にレジスト部材４を設けた後、８０℃〜１００℃の熱水に５秒〜１０分以内浸漬させることで、該レジスト部材４の存在しない部分に水を浸透させて該部分の位相差機能を消失せしめて該延伸ＰＶＡフィルム７にしてレジスト部材４が存在する部分及びレジスト部材４が存在しない部分のいずれか一方を右目用映像表示部ａ、他方を左目用映像表示部ｂとし、続いて、乾燥後前記レジスト部材４側に液晶表示部材５を該液晶表示部材５の液晶セルのピッチと前記右目用映像表示部ａ及び左目用映像表示部ｂとが合致するように重ね合わせ若しくは貼り合わせることを特徴とする３Ｄ映像表示体の製造方法に係るものである。
【０００７】
また、右目用映像表示部ａと左目用映像表示部ｂとが混在した３Ｄ映像を現出させる為の３Ｄ映像表示体の製造方法であって、透明な支持材１上に接着剤２を介してＴＡＣフィルム６若しくはＣＡＢフィルムと位相差機能を有する延伸ＰＶＡフィルム７とを積層した積層位相差フィルム３を該ＴＡＣフィルム６若しくはＣＡＢフィルムが該接着剤２側となるように設け、続いて、この延伸ＰＶＡフィルム７の所定位置にレジスト部材４を設けた後、８０℃〜１００℃の熱水に５秒〜１０分以内浸漬させることで、該レジスト部材４の存在しない部分に水を浸透させて該部分の位相差機能を消失せしめて該延伸ＰＶＡフィルム７にしてレジスト部材４が存在する部分及びレジスト部材４が存在しない部分のいずれか一方を右目用映像表示部ａ、他方を左目用映像表示部ｂとし、続いて、乾燥後前記レジスト部材４側に液晶表示部材５を該液晶表示部材５の液晶セルのピッチと前記右目用映像表示部ａ及び左目用映像表示部ｂとが合致するように重ね合わせ若しくは貼り合わせることを特徴とする３Ｄ映像表示体の製造方法に係るものである。
【０００８】
また、請求項２記載の３Ｄ映像表示体の製造方法において、レジスト部材４は延伸ＰＶＡフィルム７の一側から他側に向かう所定間隔をおいて設けられた線状体であることを特徴とする３Ｄ映像表示体の製造方法に係るものである。
【０００９】
また、請求項２，３いずれか１項に記載の３Ｄ映像表示体の製造方法において、レジスト部材４は延伸ＰＶＡフィルム７上にスクリーン印刷により設けられるレジストインクであることを特徴とする３Ｄ映像表示体の製造方法に係るものである。
【００１０】
【発明の作用及び効果】
延伸ＰＶＡフィルム７の所定位置にレジスト部材４を設けた後、湯に浸漬させると、延伸ＰＶＡフィルム７のレジスト部材４の存在しない部分に水が浸透し、該部分が変質し、該部分のみ特定の波長域の光の振動方向を直線偏光状態のまま回転し得る性質（位相差機能）が消失し、レジスト部材４が存在する部分とレジスト部分４が存在しない部分とで透過光の位相が１８０°ずれるフィルムが得られることになる。
【００１１】
よって、単に熱水に浸漬させるという操作のみで右目用映像表示部ａ及び左目用映像表示部ｂが混在したフィルムを量産し得ることになる。
【００１２】
【発明の実施の形態】
図２は本発明の実施例を図示したもので、以下に詳述する。
【００１３】
透明な支持材１（例えば厚さ２ｍｍ程度のガラス板やセルロースアセテートブチレート（ＣＡＢ）板等）上に接着剤２（例えば紫外線硬化性樹脂）を介してＴＡＣフィルム６（厚さ１２６μｍ）と位相差機能を有する位相差フィルム（１／２波長板）としての一軸延伸ＰＶＡフィルム７（厚さ３８μｍ）とを積層した積層位相差フィルム３を設け、紫外線により紫外線硬化性樹脂を硬化させる。尚、支持材１は複屈折性を有しないガラス板が最も望ましい。また、積層位相差フィルム３は延伸ＰＶＡフィルム７にＴＡＣフィルム６を積層したものの他、延伸ＰＶＡフィルム７にＣＡＢフィルムを積層したもの等でもよく、要は延伸ＰＶＡフィルム７に複屈折性を有しないフィルムを積層したものであれば積層位相差フィルム３として採用し得る。
【００１４】
続いて、この一軸延伸ＰＶＡフィルム７の所定位置にレジスト部材４としての耐水性の高いレジストインクをスクリーン印刷により施す。この場合のレジストインクは、延伸ＰＶＡフィルム７の表面に一側から他側に向かって施される１６０μｍ幅の線状体であり、この線状体は１６０μｍのピッチをおいて並設されている。
【００１５】
尚、レジストインクは上記のように等幅且つ等ピッチである必要はなく、また、線状体でなくても、例えば平面視正方形状体を千鳥状に配するようにしても良い。
【００１６】
続いて、これを８０℃の熱水に約３０秒程度浸漬し（勿論周面には適宜な防水処理を施す。)、レジストインクが存在しない部分に水を浸透させることで延伸ＰＶＡフィルム７の分子の方向性を破壊し、延伸前の状態、即ち、延伸ＰＶＡフィルム７が元来有する前記位相差機能を消失させ、レジストインクが存在する部分を例えば右目用映像表示部ａとし、レジストインクが存在しない部分を左目用映像表示部ｂとする。尚、種々実験した結果、８０℃〜１００℃の熱水に５秒〜１０分以内浸漬すれば同様に上記延伸ＰＶＡフィルム７の性質が消失することを確認している。
【００１７】
続いて、レジストインクが透明の場合にはそのまま、また、レジストインクが透明でない場合には該レジストインク除去後、内部に液晶が設けられた表示部材５とマグネット等で重ね合わせ若しくは適宜な接着剤により貼り合わせ、３Ｄ映像表示体とする。
【００１８】
レジストインクを施す位置、即ち、右目用映像表示部ａ及び左目用映像表示部ｂの位置は貼り合わせる表示部材５の液晶セルのピッチに合致するように設定する。
【００１９】
以上の製造方法により右目用映像表示部ａと左目用映像表示部ｂとが並設されたフィルムを簡易に得ることができ、よって、３Ｄ映像表示体も簡易に得ることが可能となる。
【００２０】
尚、上記製造においては各部材をロール状とすれば連続製造が可能となり、一層、３Ｄ映像表示体の量産性が向上することとなる。
【００２１】
このようにして製造した３Ｄ映像表示体からの映像を右目用映像表示部ａからの右目用映像のみを透過する偏光板付右目用レンズと左目用映像表示部ｂからの左目用映像（右目用映像を構成する光の振動方向に対し９０°直交する方向に振動する光により構成された映像）のみを透過する偏光板付左目用レンズとから成る偏光メガネで見ると、観察者は該映像を立体映像として観念し得ることになる。
【００２２】
尚、本実施例はＵＳＰ５,３２７,２８５号に開示された偏光板に右目用映像表示部及び左目用映像表示部を形成している技術とは異なり、位相差フィルムに右目用映像表示部ａ及び左目用映像表示部ｂを形成しているため、偏光光を発する表示部材５と組み合わせることが必要となる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a 3D video display for displaying 3D video.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, for example, a 3D video apparatus as shown in USP 5,327,285 has been proposed. As shown in FIG. 1, this 3D video apparatus is obtained by laminating a film 52 in which right-eye video display parts a and left-eye video display parts b are alternately arranged on the surface of a liquid crystal member 51. When the predetermined image is displayed by controlling the light emission of the member 51, the right-eye image is displayed from the right-eye image display unit a, and the left-eye image is displayed from the left-eye image display unit b. . Then, the vibration direction of the polarized light constituting the right-eye image from the right-eye image display unit a is a polarized light having an angle of 90 ° with respect to the polarization vibration direction constituting the left-eye image from the left-eye display unit b. (For example, the x component of the right-eye video composed of the two components x and y has a phase difference of 180 ° (π) with respect to the x component of the left-eye video composed of the two components x and y in the same manner. When viewing the image with polarizing glasses comprising a right-eye lens with a polarizing plate that transmits only the right-eye image and a left-eye lens with a polarizing plate that transmits only the left-eye image, You can think of the video.
[0003]
By the way, the manufacturing method of the film 52 in which the right-eye video display part a and the left-eye video display part b are alternately arranged is a TAC film as disclosed in FIG. 2 of the above-mentioned USP 5,327,285. A polarizing film obtained by laminating an iodine-treated stretched PVA film and a photoresist is coated. After exposing a predetermined portion, the stretched PVA film is treated with a potassium hydroxide solution to straighten the vibration direction of light in a specific wavelength range. It is manufactured by a method of eliminating the property (phase difference function) that can rotate in the polarization state. However, this method is a very complicated manufacturing method because it must be exposed to light after being coated with a photoresist and further treated with a potassium hydroxide solution. US Pat. No. 5,327,285 discloses several methods for producing the film 52 by chemical treatment as described above, and methods for producing the film 52 by physical treatment, etc., both of which are similarly complicated. It is a simple manufacturing method.
[0004]

[0005]
[Means for Solving the Problems]
The gist of the present invention will be described with reference to the accompanying drawings.
[0006]

And the other a left eye image display unit b, followed by the pitch and the right eye image display unit a and video for the left eye of the liquid crystal display member 5 after Drying The Les resist member 4 side liquid crystal cell of the liquid crystal display element 5 those relating to the manufacturing method of the 3D image display body, wherein a display portion b fit heavy root alignment or bonding to match.
[0008]
Further, in the method for manufacturing a 3D image display body according to claim 2, the resist member 4 is a linear body provided at a predetermined interval from one side of the stretched PVA film 7 to the other side. The present invention relates to a method for manufacturing a 3D video display.
[0009]
The 3D video display manufacturing method according to any one of claims 2 and 3, wherein the resist member 4 is a resist ink provided on the stretched PVA film 7 by screen printing. This relates to a method for manufacturing a body.
[0010]
[Action and effect of the invention]
When the resist member 4 is provided at a predetermined position of the stretched PVA film 7 and then immersed in hot water, the water penetrates into the portion of the stretched PVA film 7 where the resist member 4 does not exist, the portion is altered, and only this portion is specified. The property (phase difference function) that allows the vibration direction of light in the wavelength region to rotate in a linearly polarized state disappears, and the phase of transmitted light is 180 in a portion where the resist member 4 is present and a portion where the resist portion 4 is not present. A film that deviates can be obtained.
[0011]
Therefore, a film in which the right-eye image display part a and the left-eye image display part b are mixed can be mass-produced only by an operation of immersing in hot water.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 illustrates an embodiment of the present invention, which will be described in detail below.
[0013]
TAC film 6 (thickness: 126 μm) is placed on transparent support material 1 (for example, a glass plate having a thickness of about 2 mm, a cellulose acetate butyrate (CAB) plate, etc.) via adhesive 2 (for example, an ultraviolet curable resin). A laminated retardation film 3 obtained by laminating a uniaxially stretched PVA film 7 (thickness 38 μm) as a retardation film (half-wave plate) having a retardation function is provided, and an ultraviolet curable resin is cured by ultraviolet rays. The support material 1 is most preferably a glass plate having no birefringence. Further, the laminated retardation film 3 may be one obtained by laminating the TAC film 6 on the stretched PVA film 7, or may be one obtained by laminating the CAB film on the stretched PVA film 7, and the stretched PVA film 7 does not have birefringence. Any laminated film may be employed as the laminated retardation film 3.
[0014]
Subsequently, a resist ink having high water resistance as the resist member 4 is applied to a predetermined position of the uniaxially stretched PVA film 7 by screen printing. The resist ink in this case is a 160 μm-wide linear body applied from one side to the other side on the surface of the stretched PVA film 7, and the linear bodies are arranged in parallel at a pitch of 160 μm. .
[0015]
Note that the resist inks do not have to have the same width and the same pitch as described above, and may be arranged in a staggered pattern in a square shape in plan view, for example, instead of a linear body.
[0016]
Subsequently, the stretched PVA film 7 is immersed in hot water at 80 ° C. for about 30 seconds (of course, the peripheral surface is subjected to appropriate waterproofing treatment), and water is infiltrated into a portion where the resist ink does not exist. The directionality of the molecule is destroyed, the state before stretching, that is, the retardation function inherent to the stretched PVA film 7 is lost, and the portion where the resist ink exists is, for example, a right-eye image display portion a. The part which does not exist is set as the left-eye video display part b. As a result of various experiments, it was confirmed that the properties of the stretched PVA film 7 disappeared in the same manner when immersed in hot water at 80 ° C. to 100 ° C. for 5 seconds to 10 minutes.
[0017]
Subsequently, when the resist ink is transparent, the resist ink is left as it is. When the resist ink is not transparent, after the resist ink is removed, the display member 5 provided with a liquid crystal is overlapped with a magnet or an appropriate adhesive. To form a 3D video display.
[0018]
The positions where the resist ink is applied, that is, the positions of the right-eye video display part a and the left-eye video display part b are set so as to match the pitch of the liquid crystal cells of the display member 5 to be bonded.
[0019]
With the above manufacturing method, a film in which the right-eye video display part a and the left-eye video display part b are arranged side by side can be easily obtained, and thus a 3D video display body can be easily obtained.
[0020]
In the above production, if each member is formed in a roll shape, continuous production becomes possible, and mass productivity of the 3D image display body is further improved.
[0021]
The right-eye lens with a polarizing plate that transmits only the right-eye image from the right-eye image display unit a and the left-eye image from the left-eye image display unit b (right-eye image) When viewing with polarized glasses consisting of a left-eye lens with a polarizing plate that transmits only the light that oscillates in a direction orthogonal to the direction of 90 ° with respect to the vibration direction of the light constituting the image, the observer views the image as a three-dimensional image. You can get the idea.
[0022]
Unlike the technique in which the right-eye video display unit and the left-eye video display unit are formed on the polarizing plate disclosed in US Pat. No. 5,327,285, the present example is different from the right-eye video display unit a on the retardation film. In addition, since the left-eye image display part b is formed, it is necessary to combine it with the display member 5 that emits polarized light.
