Description

  The present invention relates to a pattern retardation member, a 3D liquid crystal panel, and a 3D liquid crystal display device.

  In recent years, techniques for expressing and viewing images and videos in three dimensions have been studied. Three-dimensional (3D) image display methods include a method using glasses and a naked-eye method. In either method, a left-eye image and a right-eye image are separately input to the left and right eyes of the observer, and a parallax is artificially created, so that it can be regarded as a stereoscopic image.

  One of stereoscopic video display systems using glasses is a polarized glasses system (passive system) (for example, Patent Document 1). FIG. 1 shows an outline of a stereoscopic image display apparatus using a polarized glasses method.

In the example of FIG. 1, the right-eye video (light) is emitted from the even lines of the liquid crystal panel 250, and the left-eye video (light) is emitted from the odd-numbered lines. The pattern phase difference member 290 has a pattern phase difference layer formed on a line corresponding thereto. That is, the right-eye retardation layer is formed on the line corresponding to the even-numbered line of the liquid crystal panel 250, and the left-eye retardation layer is formed on the line corresponding to the odd-numbered line.
The retardation layer for the right eye is, for example, a retardation layer formed by tilting the slow axis 280 of the λ / 4 plate by 45 ° with respect to the polarization axis 270 of the first polarizing plate 260, and the retardation layer for the left eye For example, a retardation layer formed by tilting the slow axis 280 of the λ / 4 plate with respect to the polarization axis 270 of the first polarizing plate 260 by −45 ° can be used.

  In the case of the stereoscopic display device having such a structure, among the linearly polarized light transmitted through the first polarizing plate 260, the right-eye light is transmitted through the right-eye retardation layer to be converted into right-circularly polarized light. The light passes through the left-eye retardation layer and is converted into left circularly polarized light.

The polarizing glasses 330 include a second λ / 4 plate 320 and a second polarizing plate 261 for both the right eye and the left eye. The second λ / 4 plate 320 converts the right circularly polarized light and the left circularly polarized light into linearly polarized light orthogonal to each other. Therefore, the second polarizing plate 261 allows only an arbitrary image among the right eye image and the left eye image. Can be transmitted.
As a result, the right-eye video and the left-eye video, which are simultaneously emitted, are separately delivered to the observer, thereby enabling stereoscopic viewing.

  In the stereoscopic display device having such a configuration, in order to separate and input the right-eye video and the left-eye video to the left and right eyes of the observer, the pattern of the pattern phase difference member is for the right eye emitted from the liquid crystal panel. Alternatively, it is required to accurately correspond to the video line for the left eye.

The patterned phase difference layer of the pattern phase difference member forms a desired alignment pattern by rubbing or photo-aligning the alignment film material formed on the substrate, and applying a liquid crystal on the alignment film. It can be produced by orientation.
As an alignment treatment method for such an alignment film, a method of controlling the direction in which a cross-linking bond is formed in a polyvinyl cinnamate alignment film by irradiating with polarized ultraviolet light (for example, Non-Patent Document 1), decomposition of a polyimide alignment film by ultraviolet irradiation. A method using a photodimerization reaction, a photolysis reaction, a photoisomerization reaction, or the like such as a method for imparting anisotropy to the reaction (for example, Non-Patent Document 2) has been reported.

  Conventionally, a glass substrate has been used as a support for the pattern retardation member. In the case of a glass substrate, since the alignment film composition is not affected by the solvent of the alignment film composition when applied to the substrate, the glass substrate can be kept flat and a uniform alignment film can be formed. .

JP 2008-299337 A JP 2000-221506 A

(M. Schadt et al .: Jpn. J. Appl. Phys. 31, 2155-2164 (1992)) (M. Nishikawa et al .: Liquid Crystals 26, 575-580 (1990))

  When a glass substrate is used as a support for the patterned phase difference member as in the prior art, the pattern phase difference member has a problem that it has a thickness and is heavy. Moreover, since pattern printing on a glass substrate cannot be performed continuously, productivity is poor.

  The present invention has been made to solve the above-described problems, and since a transparent resin base material is used, a pattern retardation member that is thinner and lighter than the conventional one is provided. Moreover, since a continuous printing is possible by using a transparent resin base material, a pattern phase difference member with good productivity compared with a glass substrate is provided.

  As a result of intensive studies to achieve the above object, the present inventors have obtained a pattern retardation member in which a desired patterned retardation layer is formed even when a transparent resin substrate is used. It was obtained and found to be suitable for the purpose.

  That is, the pattern phase difference member according to the present invention includes a pattern phase difference layer on one surface side of the transparent resin substrate.

  When the patterned retardation layer has an alignment film and a liquid crystal layer, the transparent resin base material and the alignment film are laminated via a cured resin layer, so that the transparent resin base material comes into contact with the solvent. This is preferable from the viewpoint of the uniformity of the alignment of the liquid crystal layer.

  Furthermore, since the curable resin has self-healing properties, scratches on the alignment film application surface can be prevented and the generated scratches can be repaired, which is preferable in that the liquid crystal layer does not cause alignment failure.

  In the pattern phase difference member according to the present invention, a second transparent resin substrate is laminated via an adhesive layer on the surface of the transparent resin substrate opposite to the surface provided with the pattern phase difference layer. A functional layer can be provided on the surface of the second transparent resin substrate opposite to the bonding surface with the adhesive. This is preferable because various functions can be imparted to the 3D liquid crystal panel.

  In addition, it is preferable that a functional layer is provided on the surface of the transparent resin substrate opposite to the surface provided with the pattern retardation layer in terms of providing various functions to the 3D liquid crystal panel and further reducing the weight and thickness.

  The 3D liquid crystal panel of the present invention includes the pattern retardation member.

  The 3D liquid crystal display device of the present invention includes the 3D liquid crystal panel.

  According to the present invention, there is provided a pattern phase difference member that is lighter and thinner than conventional ones, and further has a uniform alignment of liquid crystals and a patterned phase difference layer as designed.

FIG. 1 is a schematic diagram illustrating an example of a pattern phase difference member. FIG. 2 is a schematic diagram showing the principle of an example of stereoscopic vision in the polarized glasses method.

Next, embodiments of the present invention will be described in detail, but the present invention is not limited to the following embodiments.
In the present invention, circularly polarized light means not only perfect circularly circularly polarized light but also elliptically polarized light.

1. Pattern Retardation Member The pattern retardation member of the present invention is characterized by including a patterned retardation layer 20 on one surface side of a transparent resin substrate 10 as illustrated in FIG. The pattern phase difference member of the present invention is lighter and thinner than the conventional one, and the alignment of the liquid crystal is uniform, and the pattern phase difference layer as designed is formed. It can be accurately separated and delivered to an observer, and is suitably used for manufacturing a 3D liquid crystal panel.

1-1. Transparent resin substrate The transparent resin substrate used in the pattern retardation member of the present invention is a member that transmits at least visible light and serves as a support for a pattern retardation layer described later.
In the present invention, “transparent” means that the visible light transmittance is 80% or more.

The resin used for the transparent resin base material is not particularly limited, and a transparent resin base material used for a conventionally known optical film can be used, whether it has flexibility or rigidity. Good. Examples thereof include cellulose acetates such as triacetyl cellulose (TAC) and diacetyl cellulose, cellulose polymers such as cellulose esters, norbornene polymers, cycloolefin polymers, and acrylic polymers such as polymethyl methacrylate.
Among these, it is preferable to use TAC with little retardation.

  Although the thickness of a transparent resin base material is not specifically limited, For example, it is preferable that it is 20-500 micrometers, and it is more preferable that it is 40-250 micrometers.

  In the case of providing an alignment film, which will be described later, on the transparent resin base material, in order to improve adhesion, the transparent resin base material may be, for example, saponification treatment, glow discharge treatment, corona discharge treatment, ultraviolet (UV) treatment or A surface treatment such as flame treatment may be performed, and a primer layer (adhesive layer) may be provided.

  As a commercial item of a transparent resin base material, for example, as a norbornene-based polymer, a trade name Arton manufactured by JSR Corporation, a trade name ZEONOR Film manufactured by Nippon Zeon Co., Ltd., and the like can be given. In addition, in a cycloolefin type polymer, the brand name essina etc. by Sekisui Chemical Co., Ltd. is mentioned, for example.

1-2. Pattern Retardation Layer The pattern retardation layer constituting the pattern retardation member of the present invention refers to a layer in which retardation layers having different slow axis inclinations are arranged in a predetermined pattern. When the linearly polarized light is transmitted, the patterned retardation layer converts it into clockwise or counterclockwise circularly polarized light or elliptically polarized light according to the inclination of the slow axis.
The patterned retardation layer is not particularly limited as long as it gives different polarized light to the light for the right eye and the light for the left eye, but those having an alignment film and a liquid crystal layer described later easily form a desired pattern. It is preferable in that it can be performed.

  The thickness of the patterned retardation layer is not particularly limited, but is usually 50 to 2000 nm, preferably 100 to 1000 nm.

  The pattern shape of the patterned retardation layer is not particularly limited as long as it corresponds to the pattern of the right-eye image and the left-eye image emitted from the liquid crystal panel, but preferably the retardation layer has a different slow axis inclination. In this case, the width of each line is not particularly limited, but is usually about 100 to 1000 μm according to the line pattern of the liquid crystal panel.

1-2-1. Alignment film The patterned retardation layer may have an alignment film, and forms a patterned retardation layer together with a liquid crystal layer described later. An alignment film refers to a film for aligning liquid crystal molecules in a liquid crystal layer in a certain direction. The alignment film used in the present invention is not particularly limited, but a photo-alignment film described later is preferably used.

  The photo-alignment film has an alignment ability in which the alignment direction of the portion (exposed portion) irradiated by photoisomerization reaction or photodimerization reaction by irradiation of linearly polarized light is aligned in a specific direction, and includes liquid crystal molecules on the alignment film. When the retardation layer is formed, it functions to control the alignment of the liquid crystal molecules.

The alignment film is prepared by dissolving a photo-alignment material, which will be described later, in an organic solvent to form an alignment film-forming coating solution, and then, on one side of the first transparent resin substrate, a conventionally known material such as a roll coat or a slot die coat. What is necessary is just to apply | coat and form by the method.
The material for forming the photo-alignment film is not particularly limited as long as it has an alignment ability by polarized ultraviolet rays, and conventionally known photo-alignment film materials can be used.
As a material for forming the photo-alignment film, for example, a compound having an azobenzene skeleton in a molecule described in JP-A-2009-230069, a photoisomerizable material such as a polymerizable monomer having an azobenzene skeleton as a side chain, and a special material. Examples thereof include a reactive polymer containing cinnamic acid ester, coumarin or quinoline in the side chain described in JP-A-2009-230069 and a photoreactive material described in JP-A-2006-350322.

  The organic solvent is not particularly limited as long as the orientation compound can be uniformly dissolved, and examples thereof include clohexanone, methyl ethyl ketone, methyl isobutyl ketone, toluene, isopropyl alcohol, butanol and the like. Butanol is preferably used because it has little influence on the transparent resin substrate.

  The thickness of the photo-alignment film may be adjusted as appropriate according to desired performance such as alignment ability, and is preferably 1 to 1000 nm from the viewpoint of reducing costs and obtaining sufficient alignment ability. More preferably, it is 100 nm.

  A photo-alignment film in which at least one portion having a specific alignment direction is arranged in a pattern is produced by exposing twice linearly polarized light having different polarization directions, but at least one of the two exposures. Is performed through a photomask according to the pattern shape. The order of performing exposure through the mask is appropriately selected depending on the type of reaction of the photo-alignment film. Thus, a photo-alignment film in which portions having different orientation directions are arranged in a pattern is produced.

  By using the alignment film produced in this way, the portions having different alignment directions are arranged in a pattern, so that the alignment direction of the retardation layer is controlled in a plurality of directions with high accuracy and with a fine pattern. be able to. Therefore, the photo-alignment film can be used to produce a retardation film capable of patterning two or more types of optical compensation, such as converting linearly polarized light of one specific polarization direction into two or more types of elliptically polarized light having different rotation directions. Is suitable.

A pattern phase difference member is obtained by forming a phase contrast layer on an alignment film further after the manufacturing method of the above photo alignment film. Since the alignment direction of the retardation layer is controlled by the direction of the alignment ability of the alignment film, the retardation layer forms a patterned retardation layer having portions with different alignment directions corresponding to the alignment direction of the alignment film.
The pattern retardation member obtained by the above manufacturing method can control the alignment direction of the retardation layer in a plurality of directions with high precision and a fine pattern by controlling the alignment direction in the fine pattern of the alignment film. It can be suitably used for a λ / 4 plate for stereoscopic viewing.

As a material for forming the retardation layer, a conventionally known retardation layer material can be used.
An example of such a material is a liquid crystal material that exhibits a nematic liquid crystal phase. As such a liquid crystal material, a conventionally known liquid crystal material may be used, and examples thereof include rod-like liquid crystal molecules, polymer liquid crystals, and polymerizable liquid crystal compounds.
When using a polymerizable liquid crystal compound, in order to obtain an optical element having high heat resistance, it is preferable to have a polymerizable group at both ends of the molecule of the polymerizable liquid crystal compound.
In addition, the retardation layer may be a retardation layer described in JP-A-2009-162874.

1-2-2. Liquid Crystal Layer The patterned retardation layer may have a liquid crystal layer and is used in combination with the alignment film. Since the liquid crystal molecule group in the liquid crystal layer is arranged in a certain direction by the alignment of the alignment film, it is arranged in the pattern on the alignment film in which the alignment direction is patterned.

  The liquid crystal layer can be obtained by applying a liquid crystal layer-forming coating solution obtained by diluting a liquid crystal compound with an organic solvent onto the alignment film, drying it, and fixing it as necessary. The coating method may be formed by coating by a conventionally known method such as a roll coating method or a slot die coating method.

  The liquid crystal compound in the liquid crystal layer is not particularly limited, and a known compound can be used, but it is preferable that a nematic phase is expressed. This is because the nematic phase is relatively easy to control the alignment among the liquid crystal phases.

  Moreover, it is preferable to contain a polymerizable liquid crystal compound as the liquid crystal compound. This is because the alignment state of the liquid crystal can be fixed. As the polymerizable liquid crystal compound, a polymerizable liquid crystal monomer is preferably used. The polymerizable liquid crystal monomer can be aligned at a lower temperature than other polymerizable liquid crystal compounds, that is, a polymerizable liquid crystal oligomer and a polymerizable liquid crystal polymer, and has high sensitivity in alignment, and can be easily aligned. Because you can.

  The polymerizable liquid crystal monomer is not particularly limited as long as it is a liquid crystal monomer having a polymerizable functional group, and examples thereof include a monoacrylate monomer and a diacrylate monomer. These polymerizable liquid crystal monomers may be used alone or in combination of two or more.

  Examples of the monoacrylate monomer and diacrylate monomer include those described in JP-A-2006-350322, JP-A-2006-323214, JP-A-2005-258429, JP-A-2005-258428, and the like.

  Further, when a polymerizable liquid crystal compound is used, a photopolymerization initiator, a polymerization inhibitor, or the like may be added to the liquid crystal layer forming coating solution as necessary. As the photopolymerization initiator, for example, a photopolymerization initiator described in JP-A-2005-258428 can be used. Moreover, you may add a sensitizer other than a photoinitiator in the range which does not impair the objective of this invention.

The solvent used in the liquid crystal composition is not particularly limited as long as it can dissolve the liquid crystal compound and the like and does not affect the alignment ability of the alignment film.
Examples of such solvents include hydrocarbons such as benzene, toluene, xylene, n-butylbenzene, diethylbenzene, and tetralin; ethers such as methoxybenzene, 1,2-dimethoxybenzene, and diethylene glycol dimethyl ether; acetone, methyl ethyl ketone, Ketones such as methyl isobutyl ketone, cyclohexanone and 2,4-pentanedione; esters such as ethyl acetate, propylene glycol monomethyl ether acetate, propylene glycol monoethyl ether acetate and γ-butyrolactone; 2-pyrrolidone, N-methyl-2 Amide solvents such as pyrrolidone, dimethylformamide, dimethylacetamide; t-butyl alcohol, diacetone alcohol, glycerin, monoacetin, ethylene glyco Le, triethylene glycol, or hexylene glycol; phenols, phenols such as para-chlorophenol; methyl cellosolve, can be used ethyl cellosolve, butyl cellosolve, and cellosolve such as ethylene glycol monomethyl ether acetate. A solvent may be used independently and may use 2 or more types together.

  The ratio of the liquid crystal compound is usually adjusted in the range of 3 to 20% by mass, preferably 5 to 10% by mass, based on the total mass in the liquid crystal layer forming coating solution. If the concentration of the reactive liquid crystal composition is lower than the above range, the liquid crystal compound may be difficult to align. Conversely, if the concentration of the liquid crystal compound is higher than the above range, the viscosity of the liquid crystal layer forming coating liquid increases. This is because it may be difficult to form a uniform coating film.

  When the liquid crystal layer has a polymerizable liquid crystal compound, the alignment pattern can be stabilized by polymerizing and fixing the polymerizable liquid crystal compound by ultraviolet irradiation or heating.

  The thickness of the liquid crystal layer is appropriately adjusted according to the type of the liquid crystal compound and the target retardation, and can be set, for example, within a range of 1 nm to 2000 nm, preferably within a range of 500 nm to 1000 nm. It is. This is because the target phase difference cannot be achieved if the thickness of the liquid crystal layer is too thin or too thick.

1-3. Cured resin layer When an alignment film is used for the patterned retardation layer, a cured resin layer may be provided between the alignment film and the transparent resin substrate.
The curable resin for forming the cured resin layer is obtained by applying the transparent resin substrate from an organic solvent when the alignment film forming coating liquid is applied to the transparent resin substrate in the production of the pattern retardation member. It has a protective function. Since the transparent resin substrate is protected from the solvent and is not deformed or dissolved, the alignment film forming coating solution can be uniformly applied. Thereby, the alignment film becomes uniform, and the alignment of the liquid crystal layer formed thereon becomes uniform.
The curable resin is not particularly limited as long as it has solvent resistance after curing, and may be a thermosetting resin or a photocurable resin.
Examples of the thermosetting resin include homopolymers of (meth) acrylate esters such as poly (meth) methyl acrylate and poly (meth) butyl butyl; methyl (meth) acrylate-butyl (meth) acrylate (Meth) acrylic acid ester copolymers such as copolymers; Polyesters such as polyethylene terephthalate and pothibrylene terephthalate; Polycarbonate, polystyrene, polymethylpentene and the like.
Examples of the photocurable resin include (meth) acrylates such as polyfunctional urethane (meth) acrylates and polyester (meth) acrylates; (meth) acrylate oligomers such as unsaturated polyesters; methyl (meth) acrylates, ethyl ( Monofunctional monomers such as (meth) acrylate; (meth) acrylate polyfunctional monomers such as hexanediol di (meth) acrylate, trimethylolpropane tri (meth) acrylate, and dipentatrierythritol hexa (meth) acrylate.

  Furthermore, by using a resin having a self-healing property as the curable resin, it is difficult to cause scratches on the alignment film application surface, and the generated scratches are repaired. As a result, it is particularly preferable to use a resin having self-healing properties from the viewpoint that the alignment film can be applied uniformly. Self-healing is a property in which scratches and dents are generated due to friction and pressure, and temporarily exist as scratches compared to other planes, but they are repaired over time by the elastic restoring force of the resin and disappear. Say. Examples of the resin having self-healing property include a polydimethylsiloxane copolymer described in JP-A-2007-9218 in which a polysiloxane component grafted with polycaprolactone is introduced into the skeleton.

  Examples of the polycaprolactone include radically polymerizable polycaprolactone represented by the chemical formula (1).

  Examples of the polydimethylsiloxane polymer include those obtained by copolymerizing a methacrylic ester of polydimethylsiloxane represented by the chemical formula (2) and a vinyl monomer.

(In chemical formula (2), m represents an integer of 10 to 300.)

  Examples of the vinyl monomer include methyl acrylate, ethyl acrylate, n-butyl acrylate, and the like.

  The polydimethylsiloxane copolymer in which the polysiloxane component grafted with polycaprolactone is introduced into the skeleton is synthesized by adding the polycaprolactone and the polysiloxane component when polymerizing the polydimethylsiloxane copolymer. Can be obtained. For the synthesis of the polymer, for example, a known method such as a living polymerization method can be used.

  The coating composition is applied as a curable resin coating composition, and a known method can be used as the coating method. The coating method is not particularly limited, and examples thereof include a spin coating method and a roll coating method. The coating film of the curable resin is cured at an appropriate stage of the process of forming the patterned retardation layer to become a cured resin layer, but the viewpoint of reducing the influence of the solvent on forming the alignment film on the transparent resin substrate Therefore, it is preferable to be cured before the alignment film forming step.

  Although the film thickness of the said curable resin is not specifically limited, Usually, it is 1-10 micrometers, Preferably, it is 5-10 micrometers. If it is thinner than this range, the transparent resin substrate may be deformed by the influence of the solvent.
