The present invention relates to a method for producing a 3D image display body for displaying a 3D image and a film for forming a 3D image display body.

Conventionally, for example, a 3D imaging apparatus as shown in US Pat. No. 5,327,285 has been proposed. As shown in Fig. 1, the 3D imaging apparatus is formed by pasting a film 52 in which a right eye image display unit a and a left eye image display unit b are alternately arranged on the surface of the liquid crystal member 51. When the light emission of the liquid crystal member 51 is controlled to display a predetermined image, the right eye image display unit a shows the right eye image, and the left eye image display unit b shows the left eye image. In addition, 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 vibration direction of the polarized light constituting the left eye image from the left eye display unit (b). In other words, for example, the x component of the right eye image composed of two components (x, y) is similarly 180 ° (π) with respect to the x component of the left eye image composed of two components (x, y). Because it is configured to have a phase difference of, a viewer can observe a stereoscopic image with polarized glasses composed of 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. It becomes possible.

By the way, the manufacturing method of the film 52 in which the right eye image display unit (a) and the left eye image display unit (b) are alternately arranged is, as disclosed in FIG. 2 of US Pat. The photoresist is coated on the polarizing film laminated | stacked the processed stretched PVA film, a predetermined part is exposed, and it processes with potassium hydroxide solution, and rotates the vibration direction of the light of the specific wavelength range which the stretched PVA film has in a linearly polarized state. It is manufactured by the method of losing the property (phase difference function) which can be eliminated. However, this method is exposed after coating of the photoresist, and further has to be treated with potassium hydroxide solution, which is a very complicated production method. USP 5,327, 285 discloses a kind of method for producing the film 52 by the above chemical treatment, a method of producing the film 52 by the physical treatment, and the like, but all are similarly complicated manufacturing methods.

The present invention provides a film in which the right eye image display portion (a) and the left eye image display portion (b) are mixed in a very simple manner and excellent in mass productivity, and a manufacturing method thereof.

The gist of the present invention will be described with reference to the accompanying drawings.

In one embodiment of the present invention, there is provided a method of manufacturing a 3D image display body for displaying a 3D image in which a right eye image display unit (a) and a left eye image display unit (b) are mixed, on a transparent support material (1). After forming the retardation film through the adhesive agent 2, and then providing the resist member 4 at the predetermined position of the retardation film so that the right eye image display part and the left eye image display part are formed in the retardation film, and then hot water It is related with the manufacturing method of the 3D video display body characterized by superimposing or pasting the display member 5 on the resist member 4 side after being immersed in.

In addition, as a method of manufacturing a 3D image display body for displaying a 3D image in which the right eye image display unit (a) and the left eye image display unit (b) are mixed, a TAC is applied to the transparent support material (1) through an adhesive (2). The laminated retardation film 3 in which the birefringent film such as the film 6 or the CAB film and the stretched PVA film 7 having the phase difference function are laminated is formed so that the TAC film 6 is on the adhesive 2 side. Subsequently, after the resist member 4 is provided at a predetermined position of the stretched PVA film 7 so that the right-eye image display portion and the left-eye image display portion are formed on the retardation film, the resist member 4 is immersed in hot water, and then dried. The manufacturing method of the 3D video display body characterized by superimposing or pasting the display member 5 on the member 4 side.

Further, in the method for producing a 3D video 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. A method of manufacturing a video display body.

Further, in the method for manufacturing a 3D video display according to claim 2 or 3, the resist member 4 is a resist ink formed by screen printing on the stretched PVA film 7, wherein the 3D video display is It relates to a manufacturing method of.

The method for producing a 3D video display according to any one of claims 2 to 4, wherein the method for producing a 3D video display is immersed in hot water at 80 to 100 ° C for 5 seconds to 10 minutes. It is about.

In addition, a 3D image display body forming film for displaying a 3D image in which the right eye image display unit (a) and the left eye image display unit (b) are mixed, the TAC on the transparent support material (1) through the adhesive (2) A laminated retardation film 3 in which a film having no birefringence and a stretched PVA film 7 having a retardation function, such as the film 6 is laminated is provided so that the film having no birefringence is at the adhesive 2 side. In addition, the film for forming a 3D image display body, characterized in that the right eye image display unit (a) and the left eye image display unit (b) is provided at a predetermined position of the stretched PVA film (7).

If the resist member 4 is provided at a predetermined position of the retardation film, and then immersed in warm water, water penetrates into the portion where the resist member 4 of the phase film does not exist, and the portion is deteriorated. The characteristics (phase difference function) which can rotate the vibration direction of the light of a specific wavelength range in a linearly polarized state are lost, and the part which the resist member 4 exists and the part which does not exist the resist light 4 It is possible to obtain a film whose phase is shifted by 180 °.

Therefore, it is possible to mass-produce a film in which the right eye image display unit a and the left eye image display unit b are mixed only by immersion in hot water.

EXAMPLE

2 illustrates an embodiment of the present invention, which will be described in detail below.

TAC film 6 (thickness 126) through an adhesive 2 (e.g. UV curable resin) on a transparent support material 1 (e.g. a glass plate or a cellulose acetate butylate (CAB) plate having a thickness of about 2 mm). 1 m) and a laminated retardation film 3 in which a uniaxially stretched PVA film 7 (thickness 38 m) as a retardation film (1/2 wave plate) having a retardation function is laminated is formed, and the ultraviolet curable resin is formed by ultraviolet rays. Harden. On the other hand, the support material 1 is most preferably a glass plate having no birefringence. The laminated retardation film 3 may be a laminate of a TAC film 6 on the stretched PVA film 7, a laminate of a CAB film on the stretched PVA film 7, and a stretched PVA film (if necessary). If the film which does not have birefringence is laminated | stacked on 7), it can be employ | adopted as the laminated retardation film 3.

Subsequently, resist printing having high water resistance as the resist member 4 is performed at a predetermined position of the uniaxially stretched PVA film 7 by screen printing. The resist ink in this case is a 160 micrometers wide linear body implemented on the surface of the stretched PVA film 7 from one side to the other, and this linear body is provided in parallel with the pitch of 160 micrometers.

On the other hand, the resist ink does not need to have the same width and the same pitch as described above, and is not a linear body. For example, the square may be arranged in a zigzag shape when viewed in a plan view.

Subsequently, this was immersed in hot water at 80 ° C. for about 30 seconds (appropriate waterproofing was performed on the surrounding surface, of course), and water was penetrated into a portion where resist ink was not present, thereby reducing the molecular weight of the stretched PVA film 7. The fragrance is broken and the state before the stretching, that is, the phase difference function originally possessed by the stretched PVA film 7 is lost, and the portion where the resist ink is present is used as the image display unit for the right eye, for example, and the resist ink does not exist. The part which does not make it is set as the left eye image display part (b). On the other hand, as a result of various experiments, it is confirmed that the property of the stretched PVA film 7 is similarly lost when immersed in hot water at 80 ° C to l00 ° C for 5 seconds to 10 minutes.

Subsequently, if the resist ink is transparent, and if the resist ink is not transparent, after removing the resist ink, the display member 5 provided with a liquid crystal is superimposed with a magnet, or with an appropriate adhesive. Put it together to make a 3D image display.

The position at which the resist ink is applied, that is, the positions of the right eye image display portion a and the left eye image display portion b are set to match the pitch of the liquid crystal cell of the display member 5 to be fitted.

By the above manufacturing method, the film in which the right eye image display part (a) and the left eye image display part (b) were provided together can be obtained easily, and a 3D video display body can also be obtained easily by this.

On the other hand, in the said manufacturing, when each member is made into roll shape, continuous manufacture becomes possible and the mass productivity of a 3D video display body further improves.

The left eye image from the left eye image display unit (b) and the right eye lens with the polarizing plate which transmits only the right eye image from the right eye image display unit (a) When viewed with polarized glasses consisting of a lens for a left eye with a polarizing plate that transmits only an image composed of light vibrating in a direction orthogonal to the vibration direction of light constituting light, the observer can think of the image as a stereoscopic image. .

On the other hand, in the present embodiment, unlike the technique in which the right eye image display unit and the left eye image display unit are formed on the polarizing plate disclosed in USP 5,327,285, the right eye image display unit (a) and the left eye image display unit (b) are provided on the retardation film. Since it is formed, it is necessary to combine it with the display member 5 which emits polarized light.
