For example, the second retardation film may be laterally extended or longitudinally extended to 'the slow axis direction' may be parallel to the long side of the optical member or orthogonal. Further, for example, the second retardation film is obliquely extended so that the retardation axis direction ' is 45 with respect to the longitudinal direction of the optical member. The direction of the angle of the left and right (for example, 45 ° ± 5 °, with 45 ° soil 1. is preferred). Here, the in-plane phase difference "uniform" is different from the first retardation film, and does not have the meaning of a pattern composed of a plurality of types of regions. Specifically, the second retardation film is used. The dispersion of the phase difference in the plane is preferably within _2 0 nm, and more preferably within 1 〇 nm.

The direction opposite to the optical member is easy to hunt.制造 制造 乍 乍 乍 乍 乍 立体 立体 立体 立体 立体 立体 立体 立体 立体 立体 立体 立体 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The retardation film side can be adapted to the liquid crystal panel phase S. When the optical member is fed by the optical 201248244 member-substrate composite film, the surface of the composite film on the optical member side faces the liquid crystal panel. In this case, the pattern boundary The relationship between the relative positions of the black matrices and the relative positional relationship when viewed from the direction perpendicular to the display surface of the liquid crystal panel (hereinafter, such a positional relationship is referred to as a "position on the plane"). The situation.). The positioning, in particular, is located on the black matrix when viewed from the direction perpendicular to the display surface of the liquid crystal panel. More physically, the pattern boundary line in the display surface area (the area of the pixel of the liquid helium panel when viewed from the direction perpendicular to the display surface) is located in the black matrix to divide the complex array pixels in the panel into groups. Partially positioned. Fig. 2 is a schematic view showing a pattern boundary line and an example of the above. In the example of Fig. 2, the liquid crystal panel 4 phase = liquid crystal panel for the relational image display device has a two-motion type of vertical observation material group; 5 (one) has 2,! The pixel group' is the image of the right pixel group and the image viewed by the left eye.

And the pixel constitutes two pixel pixels R1, pixel Q G2, and the entangled first pixel group 'pixel Μ, image φ, and 第 into the second pixel group. In the stupid country of each pixel group, the stupid pixels arranged in the direction are arranged in the column 41 and the axis γ direction of the pixel group of the pixel 42β pixel of the pixel group of the second pixel group, and f1, '1 And 42, in the coordinate-side scanning observation, H can be arranged 'from one end of the direction to .... . Therefore, it is observed that the column matrix in which the direction of ... is extended in the X direction of the coordinate axis: the:: pixel group, separated by a black member, 俜第士士77. In this example, the first phase difference of the light system 臈1〇(four) the pattern boundary of the ridges 11 and 12 is 20124824415, and the pixel is located on the portion 45 of the black matrix. Thus, the pixels of each pixel group are along the rectangle. In the aspect in which the display is arranged in the parallel direction, the manufacturing method of the present invention is carried out using an optical member having a pattern boundary in the longitudinal direction, whereby the accuracy of the position can be improved. In addition, the 彳 is cut along the longitudinal direction of the optical member with the long strip: the optical member is cut and the vertical line is cut, and the utilization efficiency of the optical member can be improved. The pattern boundary and the black matrix on the retardation film of step (8) 1 i are added. The relative position of the device [can be observed using a device containing a camera and a light source. More specifically, a camera and a light source are attached, and are observed by means of a device having a circular or polarizing plate included in either or both of them. An example of observing the position of the pattern on the first retardation film and the relative position of the black matrix will be described with reference to Fig. 3 .胄3 is a perspective view showing an example of an observation state of a liquid crystal panel and other layers. In this example, the second retardation film 10 and the second retardation film 2 are disposed. , polarizing plate 3. And the state of the liquid crystal panel 4', the pattern on the liquid crystal panel 40 and the first retardation film 1 is observed by the observation device 90. Arrow A11413 indicates the optical path at the time of observation. In Fig. 3, the optical path is shown obliquely for illustration, but in practice, the optical path toward the camera 92 can be substantially perpendicular to the liquid crystal panel 40. 3, the first retardation film 10, the second retardation film 2, the polarizing plate 30, and the liquid crystal panel 40 are shown in isolation, but some or all of them are in actual form. It is supplied to the step (B) in a contact state. Specifically, the first retardation film 10 and the second retardation film 2 are provided as members included in the optical member, and are supplied to the step (B) either directly or as necessary via the bonding of the layers. Further, the polarizing plate 3 is supplied to the step (B) either directly or in a state of being adhered to the second retardation film 2 or the liquid crystal panel 经由 via the adhesive layer. In this case, the polarizing plate 3 has a transmission axis in the coordinate axis γ direction. The second retardation film is formed at 45 with the transmission axis of the polarizing plate 3A.

The light reaching the liquid crystal panel 4A by the light source 91 (arrow A11) is emitted through the polarizing plate 30, the second retardation film 20, and the first retardation film 10. Here, the polarizing plate 30 has a transmission axis in the coordinate axis γ direction, and the second retardation film is formed at 45 with the transmission axis of the polarizing plate 30. Since the angular direction has a 1/4 wavelength plate of the slow phase axis, the light emitted from the second retardation film 20 becomes circularly polarized. The light incident on the isotropic region 12 when the circularly polarized light penetrates the second retardation film 1 出 is emitted by circularly polarized light having the same rotational direction as the incident light. On the other hand, the light incident on the region u which is the half-wavelength plate is emitted by the circularly polarized light in the rotation direction opposite to the incident light. Further, by passing through the circular polarizing plate 93 for observation, one of the two types of circularly polarized light (arrow A12) will penetrate, and the other (arrow A13) will be absorbed or reflected. Therefore, only one of the two types of circularly polarized light can be observed. Therefore, the state of the circular polarizing plate 93 is passed, and the camera 92 is focused on the surface of the table 15 201248244 of the i-th retardation film, and the other side is observed, and the pattern on the first retardation film is observed.

As a result, when the two positions are carved by the desired position, the relative position can be adjusted to the desired position. The optical member, when viewing the liquid crystal panel, continues to view the panel in a state where the optical member is fixed, and at the same time, by moving the liquid crystal panel to position the matrix of the recorded pattern boundary I to a desired state, the positioning can be performed efficiently. The position observed at the time of positioning is not particularly limited, and two or more points on the optical member and the liquid crystal panel may be used as observation points.

The distance of the sporadic contact is far enough, and the distance as close as possible is better. The tension applied during positioning can be determined according to the size of the display surface area 'the performance of the composite film' is preferably 〇·1 Omm. It is preferable that the optical member and the liquid crystal panel are positioned to be in contact with each other via a layer such as a bonding layer, and the optical member and the liquid crystal panel can be folded. The layer can be positioned by the appropriate one, and the optical structure panel can be positioned in contact with the layer via the adhesive layer or the like.

In the step (A), the optical member is fed out as an optical member-substrate composite film, and when this is directly supplied to the step (c), the tension can be applied to the optical member-substrate composite film. In the manufacturing method of the present invention, the specific optical member is sent out in the step (A), and in the step (c), the tension is applied in a state in which the longitudinal direction is applied, and the pattern boundary can be accurately and accurately The black matrix clamp can be used to manufacture a lightweight liquid display device having a patterned retardation film at an efficient and low cost. That is, it is possible to replace the film using a specific optical member using a pattern phase difference plate having a glass plate as a substrate in the prior art, and it is possible to achieve improvement in manufacturing efficiency and weight reduction of the device, and it is possible to use the film 19 201248244. The pattern boundary of the problem and the black matrix 2Ε ^ ± ^ the precision of the hunger is increased by applying tension. Specifically, for example, when the optical member in which the pattern boundary line is extended in parallel with the longitudinal direction of the learning member is shown in FIG. 1 , the first member is twisted, and the straightness of the pattern boundary is impaired. Precisely positioning the pattern boundary and the black matrix 'Precision by applying tension to step (6)' - can improve the straightness of the (four) boundary (ie, closer to the straight line), and can perform more precise positioning. The bonding in the step (6) is performed by bringing the optical member and the liquid crystal panel into contact via a layer such as an adhesive layer, and performing appropriate squeezing and holding using a flattening roller or the like. The clamping force at the time of clamping can be 3 or less. By the low sweet pressure clamping, the uneven thickness of the adhesive layer due to the movement of the flattened parent wheel can be reduced. Further, it is possible to prevent the heavy stress between the imaginary layer of the optical member or the like due to the movement of the flattening roller, and to inadvertently shift the proper bonding position. The lower limit of the clamping pressure is not particularly limited. . Grab the above. The flattening roller can be used satisfactorily on the surface of the shaft made of sus, rubber roller or Teflon (registered trademark) Teflon (registered trademark). As the material of the rubber, nitrile butadiene rubber, ruthenium rubber, styrene butadiene rubber, or the like can be suitably used. The roller L is usually l〇mm or more and 3〇〇mm or less, preferably 5 〇 or more and 00 mm or less, and if it is 10 mm or less, the winding force in the width direction is easily made by the house force at the time of sticking to 300 or more. , the weight is too large, it is difficult to control the pressure when pasting. The rubber hardness is usually 100 degrees or less, preferably 30 degrees or more and 90 degrees or less. Below 10 degrees, the pressure at the time of sticking is not sufficient. 20 201248244 Ground load 'South over 1 fj Choice θ, , Α χ The rubber surface cannot follow the surface of the bonded substrate, and it is not easy to bite. [Arbitrary Steps] The manufacturing method of the present invention can be carried out in addition to the steps as described above. For example, after the above steps (8) and (6), the step (D) of biting the upper member of the optical member, applying a tensile load, and adjusting the relative position of the pattern boundary and the black matrix may be performed. The step (D)' is performed by fixing the optical member or the liquid crystal panel to the other side and applying a load to the other. The tensile load can be 5 N/l 〇〇〇 mm or more. The direction in which the load is pulled, in the in-plane direction parallel to the display surface of the liquid crystal panel, reduces the direction of the offset of the position. The relative position of the pattern boundary to the black matrix can be finely adjusted by performing this step (D)'. For example, although the step (B) has been precisely positioned, the positional fine adjustment can be performed when the positional shift is performed in the step (c). The partial spears of the relative positions of the pattern boundary and the black matrix after the above step (C) can be observed in the same manner as in the above step (8). By performing such observations in turn, and by adjusting the position of step (D), it is possible to surely eliminate the slight offset of the position. As another arbitrary step, after the steps (β) and (c), the step (E) of irradiating the energy layer to the adhesive layer to harden the adhesive layer may be performed. The energy ray ' can use an ultraviolet ray, a visible ray, an electron beam or the like for hardening the resin, and is particularly excellent in ultraviolet ray. More specifically, t is an ultraviolet light having an emission wavelength of 3 〇〇 nm to 40 〇 nin. A preferred light source is a two-time mercury lamp and a halogen lamp. 21 201248244 When step (8) is carried out, as the material of the receiving layer, the selection is suitable for step 66 ^ M , ^ The layer of the connector is not applied in step (C) and is defoamed by the energy "BS edge overflow" Good good ' yi fc,, " Bei is now strongly strong material is better. - ° ° force is usually 0. 5N / 25mm or more, to 2N / 25mm, the upper limit of the force 'not particularly limited', for example The liquid crystal display device manufactured by the manufacturing method of the present invention is provided with a polarizing plate on the display surface side of the liquid crystal panel (in the example of the polarizing plate 3 of the example of FIG. 3), and the liquid crystal panel can be formed on the opposite side. The light source side has a polarizing plate. Therefore, the present hair

The manufacturing method of Ming, can be sentenced to the sentence of the water source side of the light source side of the sentence 句a δ. This step is performed on the surface on the light source side of the liquid crystal panel, and is adhered to the polarizing plate via the connector layer as necessary. The adhesion of the polarizing plate on the light source side can be carried out at any stage of the manufacturing method of the present invention, preferably after steps (B) and (c). Further, when the manufacturing method includes the step (D), the step (E), or both of the above, it is preferred to carry out after the steps. The reason is as follows. In other words, when the light source and the camera are positioned in the step (B), the polarizing plate on the light source side is provided, and the incident light is absorbed by the polarizing plate on the display surface side during reflection, and it is difficult to observe the black matrix. On the other hand, before step (β) and other positioning steps are performed before the polarizing plate on the light source side is disposed, the black matrix is easily observed at the time of positioning. This advantage is particularly remarkable when a black matrix type panel is used as the liquid crystal panel. Further, the liquid crystal display device can be manufactured by any step other than the above-mentioned 22 201248244 as appropriate. For example, in the laminate including the liquid crystal panel and the optical member, the step of arranging the additional optical member to enhance the brightness is appropriately arranged. Examples of such additional optical members include an antireflection film, an antiglare film, an antiglare film, a hard coat film, and a tantalum film. These additional learning members can be disposed, for example, on the viewing side of the optical member provided in the above step. The base material of the additional optical member is preferably ruthenium which is excellent in hand-resistant grease, and examples thereof include 'triethyl cellulose resin, denatured acryl resin, and polycarbonate resin. In the case of the thickness of the member, the thickness of the member is preferably (10), and (10) is preferable. For example, a frame for constituting the liquid crystal display device, an energizing device, and the like can be appropriately disposed. [Embodiment] Next, an embodiment of a more specific embodiment of the manufacturing method of the present invention will be described. Fig. 4 is a perspective view schematically showing an example of a series of apparatuses for carrying out the manufacturing method of the present invention and an operation thereof. 4. The liquid crystal panel 4A has a pixel array of two pixel groups as described with reference to Fig. 2. The laminate of the liquid crystal panel 40 and the polarizing plate 30 is placed horizontally on the display surface side of the liquid crystal panel. In the conveyance device, the conveyance device is conveyed by the conveyor. First, the adhesive is applied by the coating device 61 to form the adhesive layer 62. Thereafter, the laminate of the liquid crystal panel 4 is placed and conveyed in the direction of the arrow A1. And placed on the stage 51. The liquid crystal surface 4 is further fixed to the stage 51, whereby the position of the liquid crystal panel 40 can be adjusted by moving the stage 51. 23 201248244 Round 8 arrow arrow A2 The composite film 82 of the substrate composite film is fed in the direction (step (A)). Here, the composite film 82 has (substrate) - (first retardation film) _ (adjacent layer) _ (second The film of the layer of the retardation film) and the retardation film of the composite film 82 have the pattern described with reference to Fig. 1. In this case, the substrate is formed using a pattern of an optical member which does not interfere with the positioning step. Observation (for example, the in-plane phase difference is 1 or less), the use of the layer can be cured by exposure to ultraviolet rays, and the final adhesive can be used. The composite film 82 is sent with a cutter 52. The slit is cut into a layer other than the substrate, whereby the 'optical member (composed of the ith retardation film, the adhesive layer, and the second retardation film) is cut in the width direction to be a size suitable for the display surface region of the liquid crystal panel. Thereafter, the composite film 82 is further conveyed and sent to the upper side of the stage 51 (step (A)). Here, the composite film 82 is fed on the side of the substrate side. In this example, the composite film 82, Rollers 83 and 84 and other suitable means (flattening roller, suction roller) The floating roller or the like does not have a picture. 'Appropriate tension is applied to the longitudinal direction (in this example, the coordinate axis direction), and is directly supplied to the subsequent steps. Next, the pattern boundary in the composite film 82 and the liquid crystal panel 4 are applied. Positioning of the relative positional relationship of the black matrix in the crucible (step (Β)). Positioning, the composite film 82 and the liquid crystal are observed by an observation device including a light source 91, a camera 92, and a circular polarizing plate for observation (not shown). The panel 40 is moved by moving the stage 51. The movement of the stage 51 is performed in the direction of the coordinate axis X, and the movement in the direction of the coordinate axis is performed in one or more of the rotation in the pupil plane. In the positioning, the optical member (composed of the first retardation film, the adhesive layer, and the second retardation film among the layers 24 201248244 constituting the composite film 82) is separated from the liquid crystal panel 40. ~ In this example, the observation position for positioning on the XY + surface may be the edge of the display surface area. In this example, it can be observed at any point where the liquid crystal panel and the optical member overlap, so it is necessary to The point near the center of the display area is observed. In addition, the number of positions to be observed, for the purpose of correct positioning, the shirt is 2 or more points. The viewpoint of coordinating the positioning of the shouting with the simplification step is usually performed at a corner of the rectangular display surface area of the four corners. Fig. 5 is a plan view schematically showing a preferred example of the positioning of the manufacturing method of the present invention on the χγ plane. In Fig. 5, the four corners of the display surface area 46 on the inside of the liquid crystal panel 40 on the stage are defined, and the observation points 94A to 94D are defined. Among these observation points, by observing two or more points, preferably four or more points, positioning can be performed accurately and efficiently. It is preferable to observe at two points in parallel or perpendicular to the column of pixels in the direction parallel to or perpendicular to the column of pixels. In this case, it is two points along one side of the rectangular display surface area (for example, points 94Α and 94Β). Or point 94Α and 94C, etc.) for observation. In this case, the pattern boundary and the black matrix are directly observed. Therefore, it is necessary for the observation point to be in the display area. However, if the positioning mark ' is provided in advance outside the display surface area of the optical member and the liquid crystal panel, the observation point can be positioned outside the display surface area by the mark. The shape of the sensory measurement bit may be the same as a rectangle or the like. For the multi-angle positioning mark, a specific example suitable for photographing such a shape may be appropriately selected, and may be a triangular shape, a shape of a shape, or a circular or elliptical shape, and 25 201248244 lengths of three line-aligned edges are separated by a parallel arrangement shape. The cross shape of the intersection of the two lines is marked by a plurality of elements. After the positioning is completed, the light source 91 and the camera 92 are raised, and the flattening roller 85 is disposed on the composite film 82. Further, the stage 51 is vertically raised by maintaining the state of the tension applied to the composite film 82, and the optical member and the liquid crystal panel 40 are brought into contact via the polarizing plate 30 and the adhesive layer 62. Observing the pattern boundary and the black matrix, if the offset is caused by the contact operation, the positioning can be performed again. Thereafter, the flattening disc 85 is used to apply pressure to the liquid crystal panel 40 side of the liquid crystal panel 40, whereby adhesion of the optical member to the liquid crystal panel can be achieved (step (C)). Fig. 6 is a view showing a specific aspect of the pasting using the flattening roller 85. As shown in Fig. 6, the flattening roller 85 is attached to the stage 51 side, and is rolled in the direction of the arrow A3 to flatten the roller 85 and the stage 51 to form the composite film 82 (including the substrate 9). In addition to the optical member 8, the optical member 8 further includes a second retardation film 10, an adhesive layer 63, and a second retardation film 20), and is laminated to the liquid crystal panel 40, the polarizing plate 30, and a laminate composed of 62 layers. On, and can achieve adhesion. Next, with respect to the composite film 82 or the liquid crystal panel 4, the relative position of the pattern boundary line and the black matrix is adjusted as necessary (step (D)). The adjusted tensile load can be applied, for example, in any direction within the X gamma plane. The weight of the adjustment may be applied to the side of the composite film 82, but the tension applied to the composite film 82 side in the step (8) may be maintained, and the load applied to the stage 5u may be adjusted. Then, the state in which the composite film 82 is applied is maintained, and the adhesive layer 82 is irradiated to the adhesive layer 26 201248244 62 (step (E)). This fixing can be carried out in a part of the surface of the optical member, or can be carried out in full. When a part of the surface is formed, as shown in Fig. 7, the side of the composite film 82 is irradiated with ultraviolet rays by a lamp 〇. More specifically, as shown in FIG. 8, the four points of the points l〇4A to 104D of the liquid crystal panel 40 in the plane of the four sides of the display surface area 46 are irradiated with ultraviolet rays, and are fixed at four corners. ° By this position, the fixing is achieved quickly and without detracting from the quality of the display surface. On the other hand, for the full fixing, as shown in Fig. 9, 'fixing can be achieved by using a lamp 1〇2 which is fully irradiated with ultraviolet rays. After the fixing is completed, the device supporting the composite film 82 is raised, or the stage 51 is lowered, or by the two sides 'as shown in FIG. 1A, the substrate is made of the optical member 8 (including the first phase difference 胄1 ( ), the layer 63 and the retardation film 2 are peeled off. Thereafter, the liquid crystal panel 4 will be laminated. Further, the laminate of the optical member and the other layers is further conveyed to the square & shown in the figure A4 of the figure, and the entire layer of the contact layer 6 2 is further hardened by the lamp 103 as necessary. On the other hand, the peeled substrate 9 can be taken up by the winding roller 86, whereby a plurality of liquid crystal display devices are continuously manufactured, and the hair can be smoothly supplied to the next one. The laminated composite film 82 is transferred to the stage 51. (1) Solid-adhesive [Specific example of the production method and the second embodiment] Next, another example of the specific implementation of the method for producing the sputum and the method of the present invention will be described. J. FORM FIG. U is a schematic elevational view showing another embodiment of the apparatus and its operation for carrying out the invention. In the series: 14〇, as described with reference to Fig. 2, the liquid crystal panel has a column of pixels of 2 pixel groups. 27 201248244 The liquid crystal panel 140 is located outside the display surface area and has an alignment mark (not shown) corresponding to the position of the black matrix. The layered product ' of the liquid crystal panel 140 and the polarizing plate 30 is placed horizontally on the display surface side of the liquid crystal panel, and is transported by the conveyor. In the transfer process, the adhesive agent is first applied by the coating device 61 to form the subsequent layer 62. Thereafter, the laminate of the liquid crystal panel 14 is placed and further conveyed in the direction of the arrow A1. On the other hand, the composite film 182 of the optical member-substrate composite film is fed by the roller 181 in the direction of the arrow A2. Here, the composite film 182 has a film having a layer of (substrate)-(first retardation film)-(adjacent layer)_(second retardation film), and the phase difference of the composite film 182 The film has a pattern as described with reference to Fig. 1. In this example, since the substrate is peeled off in advance, it is not necessary to use an isotropic material (that is, a material having an in-plane retardation of more than 5 Å). Further, the adhesive layer can be cured by irradiation with ultraviolet rays, and the final layer can be used. After the fed composite film passes between the rolls 183 and 184, the substrate 9 is peeled off from the optical member 11b, and only the substrate 9 is guided in the direction of the take-up roll 185. On the other hand, the optical member 11 turns to the direction of the arrow A5. When passing the roller 186, the optical member 11 is merged with the laminated liquid crystal panel 140, and is guided to the direction of the arrow A6, as shown in Fig. 2, with two sets of rollers 187U and 187L, and 188 [ The T state controlled by J and 18乩 passes between these. The rollers 18 and 188L are movable up and down and the blades are attached to the upper side, whereby the laminate can be held. Thereby, the optical member 110 is placed on the polarizing plate 3A via the contact layer 62, and is placed in the state of 28 201248244. However, since the adhesive layer 62 has not been irradiated with ultraviolet rays and a high pressure to the extent of adhesion is not applied, the optical member 11 is not fixed to the polarizing plate 30 as long as the XY plane is subjected to the parallel direction force. It can be folded and can be peeled off as necessary. The laminate including the liquid crystal panel 140 and the optical member 11A is further conveyed in the direction of the arrow A7 as shown in FIG. 13, and the optical member is cut into a desired size by the cutting edge 154, and is further conveyed. And guided between the stage 151 and the adsorption plate 152. As shown in Fig. 14, a laminate including the liquid crystal panel 140 and the optical member 11A is placed between the stage 151 and the adsorption plate 152, and sandwiched therebetween. The liquid crystal panel 14A is further fixed to the stage 151, whereby the state of the position of the liquid crystal panel 140 can be adjusted by moving the stage 151. The adsorption plate 52 has a suitable adsorption device on the lower surface. (not shown) 'This absorbs the upper surface of the optical member i 1 。. In a state where the optical member 11 is sucked, the adsorption plate i 52 is folded in the direction parallel to the XY plane and the rotation direction, and the positioning can be performed (step (8)). Here, the adsorption plate 152 is preferably a region in which the entire surface of the display surface region of the optical member is adsorbed, and the quality of the display surface of the obtained liquid crystal display device is improved. However, when such adsorption is performed, the pattern boundary line and the black matrix in the display surface area are hidden by the adsorption plate 152 during the positioning observation, and cannot be directly observed. Therefore, in this example, the positional mark provided at a position outside the display surface area of the liquid crystal panel 14 is observed, and the positional relationship between the optical member 1 and the pattern boundary outside the visible area is performed. Observation of the relationship. Such observation can be performed by the light source 91 provided in the region 29 201248244 around the adsorption plate 152, the camera 92, and a circular polarizing plate for observation (not shown). After the positioning is completed, the light source 91 and the camera 9 2 are raised, and the flattening roller 189 is placed on the optical member 11A. As shown in Fig. 15, by temporarily lifting the suction plate 152, the roller 189 is pressed in the direction of the arrow A8 to apply tension to the optical member 11, and the optical member is brought into contact with the pressure applied to the adhesive layer 62. . Thereby, the optical member 11A and the liquid crystal panel 140 can be pasted via the adhesive layer 62 (step (C)). After the end of the pasting, as shown in FIG. 6, the laminate including the liquid crystal panel i 4 and the optical member 110 is conveyed in the direction of the arrow A8, and the lamp 10 is further irradiated with ultraviolet rays. Layer 62 is then cured. [Specification of the third embodiment of the production method] Next, another example of the embodiment of the production method of the present invention will be described. Fig. 17 is a schematic elevational view showing still another example of a series of apparatus and its operation for carrying out the manufacturing method of the present invention. In this embodiment, the laminate layer 6 is not provided on the laminate of the liquid crystal panel and the polarizing plate 30, and the layer 462 is provided on the surface of the polarizing plate 30 connected to the composite film 482, and the first embodiment is used. different. In Fig. 17, the liquid crystal panel 40 and the polarizing plate 3 are the same as those of the user of the first embodiment, but are transported and placed on the stage 51 without being applied by the adhesive layer. On the other hand, the roller 481 is used to feed the composite film 482 ' of the optical member _ base material composite film and the composite film ‘ of the protective 胄 layer for protecting the 胄 layer in the direction of the arrow A2 (step (Α)) β is a film composed of a layer of a substrate (first retardation film) - (adjacent layer) - (second retardation film) - (adjacent layer) - (protective film). The protective film has a function of protecting the adhesive layer when the composite film 490 is in a roll state. The first retardation film which is common to the composite film has a pattern described with reference to Fig. i. In this example, the substrate The observation of the pattern of the optical member that does not hinder the positioning step (for example, the in-plane phase difference is 50 nm or less) is used. Further, the adhesive layer can be cured by irradiation with ultraviolet rays, and the final adhesive can be used. The fed composite film 490 is separated into a composite: 82 and a protective film 489 when it is contacted with the roller 491. The composite film 482 has a (substrate) _ (the first) because of the residual of the protective film 489 which is peeled off by the composite film 490. i retardation film) - (adjacent layer) - (second retardation film) _ (adjacent layer In the composite film 482, a slit is cut into a layer other than the substrate by the cutter 52. Thereby, the optical member (composed of the first retardation film, the adhesive layer, and the second retardation film) and the adhesive layer are wide. The direction is cut to a size suitable for the display surface area of the liquid crystal panel. Thereafter, the composite film 482 is further conveyed and sent to the upper side of the stage 51 (step (A)). Here, the composite film 482 is made of the substrate side. In this example, the composite film 482 is formed by the rollers 83 and 84 and other appropriate means (flattening roller, suction roller, floating roller, etc., without drawing). The lateral direction (in this example, the coordinate axis χ direction) is applied to the appropriate step ' directly to the subsequent steps. Next, 'the positional relationship between the pattern boundary in the composite film 482 and the black matrix in the liquid crystal panel 4 is positioned ( Step (Β)). After the positioning is completed in the same manner as in the embodiment of the 31st 201248244 1 , the light source 91 and the camera 92 are raised, and the flattening roller 85 is disposed on the composite film 82. Maintaining the sheet applied to the composite film 482 In a state where the stage 51 is vertically raised, the optical member and the liquid crystal panel 40 are brought into contact via the polarizing plate 30 and the bonding layer 462. At this time, the pattern boundary and the black matrix can be observed again if necessary, and the partial operation is caused by the contact operation. After the shifting, the positioning can be performed again. Then, using the flattening roller 85, the composite film 482 is pressed against the liquid crystal panel 40 side to apply pressure, and the adhesion between the optical member and the liquid crystal panel can be achieved (step (C)). The specific aspect of the sticking using the flattening roller 85 is shown. As shown in Fig. 18, the flattening roller 85 is attached to the stage 51 side, and is rolled in the direction of the arrow A3 to flatten the roller 85. And the stage 51, the composite film 482 (including the substrate 9, the optical member 8 and the adhesive layer 462, the optical member 8 progressive package 3, the first retardation film 10, the adhesive layer 63, and the second retardation film 2) are pressed. It is connected to the laminate of the liquid crystal panel 40 and the polarizing plate 30 to achieve adhesion. Next, for the composite film 482 or the liquid crystal panel 4, the relative position of the pattern boundary line and the black matrix is adjusted as necessary (after step (step), the composite film 482 is fixed (step (E)). Position adjustment and fixation The same operation as in the first embodiment can be performed. After the fixing is completed, the device supporting the composite film 482 is raised, or the stage 51 is lowered, or the substrate 9' is formed by the two sides as shown in FIG. The optical member 8 (including the first retardation film 1A, the adhesive layer 63, and the second retardation film 20) is peeled off. Thereafter, the liquid crystal panel 4, the optical member 32 201248244 8 , the subsequent layer 462, and other layers are laminated. The direction indicated by the layer head A4 is carried out 'step by arrow of Fig. 17 and then with the lamp 1 〇 3 who - the whole hardening of the cow 46 46. The other step is to take up the picker layer 86, thereby The base material 9 can be wound up by a light wheel, and the liquid crystal display for the next-pointing is placed on the 'slipy D film 482, which is transported to the ay μ [liquid crystal display device] 戟σ 51.

Board 30. The light that has passed through the light source side polarizing plate 31, the liquid crystal panel 4A, and the viewing side polarizing plate 30 is linearly polarized and emitted. The transmission axis of the viewing side polarizing plate is in the vertical direction as indicated by the arrow "the direction of polarization of the light emitted from the viewing side polarizing plate 30 is indicated by the arrow A". The second retardation film 20 is a film which acts as an i/4 wavelength plate for the transmitted light, and has a uniform phase difference in the plane. The retardation axis of the second retardation film 2A is a direction of an angle of 45 with respect to the polarization transmission axis of the viewing-side polarizing plate 3A as indicated by an arrow A".

The directional region u and the strip-shaped isotropic region 12. Here, the in-plane phase difference of the anisotropic region 11 is the i/2 wavelength of the transmitted light, and the slow phase axis of the anisotropic region 11 is like an arrow. Α ι ι 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 The light 'transforms into a circularly polarized light having an inversion rotation direction by an arrow _ Am Am Am. On the other hand, the in-plane phase difference of the isotropic region 12 is zero, and therefore, is emitted by the second phase difference 胄20. The light that penetrates the isotropic region 12 among the circular polarized light will be as many as the arrow A2 32, and the target girl & The circular polarized light having the same rotational direction as before the penetration is emitted. In this example, the observer passes through the polarizing glasses 3 to observe the display surface of the device 2 。. The polarized glasses 300 are sequentially provided with a 1/2 wavelength plate 3 〇, Μ Wavelength plate 32° and linear polarizing plate 330. The slow phase axis of the 1/2 wavelength plate 310 is as shown by the arrow A3" to the stereoscopic image display device side... and the anisotropy region u of the phase difference film 10 The phase axis is in the orthogonal direction (i.e., the vertical axis of the 1/4 wavelength & 320 is the arrow a". The retardation axis of the second retardation film 2〇 of the stereoscopic image display device is shown. In the orthogonal direction, the polarization transmission axis of the linear polarizing plate 330 is an arrow-.*, and the polarization transmission axis of the viewing-side polarizing plate 3G of the stereoscopic image display device 200 is parallel: the direction (ie, the vertical direction). The 1⁄2 wavelength plate 31 〇M is provided in a portion corresponding to the right eye of the polarizing glasses 300, but the portion corresponding to the left eye is not provided. With such a wave plate configuration, the light R reaching the right eye and the light reaching the left eye are provided. l The structure of the wavelength plate that is transmitted is 'between the stereoscopic image display and the polarized glasses 300 In this way, the wavelength dispersion generated in each wavelength plate is eliminated, and the wavelength of the light R reaching the right eye and the light 1 reaching the left eye are dispersed, and the same as the incident light (the polarization in the direction of the arrow Am), A color difference will occur in the image viewed by the right eye and the left eye. 35 201248244 The light R emitted from the anisotropic region 11 is incident on the portion of the right eye of the corresponding polarizing glasses 300, and penetrates the 1/2 wavelength plate 31 0. R is converted into a circularly polarized light having an inverted rotation direction as indicated by an arrow Asid, incident on the 1/4 wavelength plate 320. The light penetrating the quarter-wavelength plate 320 is converted into a straight line having a polarization axis in the vertical direction. The polarized light is therefore able to penetrate the linear polarizing plate 330. Therefore, the light r transmitted through the anisotropic region 11 can be visually recognized by the user's right eye. On the other hand, when the light R emitted from the anisotropic region 11 enters the portion of the left eye corresponding to the polarized glasses 300, the light r does not change the polarized light and enters the quarter-wave plate 320. The light that has penetrated the quarter-wavelength plate 320 is converted into linearly polarized light having a polarization axis in the horizontal direction, and therefore cannot penetrate the linear polarizing plate 330. Therefore, the light r transmitted through the anisotropic region n cannot be visually recognized by the user's left eye. Further, when the light L emitted from the isotropic region 丨2 is incident on the portion of the left eye of the corresponding polarizing glasses 300, the light 1 is incident on the quarter-wave plate 320 without changing the polarized light. The light that has penetrated the quarter-wavelength plate 32 turns into a linearly polarized light having a polarization axis in the vertical direction, and therefore can penetrate the linear polarizing plate 330, so that the light 1 transmitted through the isotropic region 12 can be used. The left eye is visually recognized. On the other hand, the light L emitted from the isotropic region 12 is incident on the portion of the right eye of the corresponding polarizing glasses 30 0 and penetrates the 1/2 wavelength plate 31 〇, and the light 1 is converted into a rotating direction having a reverse direction. The circularly polarized light (i.e., in the opposite direction to the arrow A3l) is incident on the quarter-wavelength plate 320. The light 'transmitting through the quarter-wavelength plate 320' is converted into a linearly polarized light having a polarization axis in the horizontal direction, and therefore, 36 201248244 cannot penetrate the linear polarizing plate 330. Therefore, the light L transmitted through the isotropic region 12 cannot be visually recognized by the user's right eye. In this manner, the user views the light that penetrates the anisotropic region 11 with the right eye, and the light that penetrates the isotropic region 12 is viewed with the left eye. Therefore, by displaying the image for the right eye in the liquid crystal cell corresponding to the anisotropic region 11, the liquid crystal cell corresponding to the isotropic region 1 2 displays the image for the left eye, and the user can visually recognize the stereo image at this time. Since the device 200 includes the first retardation film 10, the phase difference between the anisotropic region 11 and the isotropic region 12 can be accurately aligned with the position of the pixel. Therefore, the quality of the stereoscopic image display device 200 can be improved. Fig. 21 is an exploded perspective view showing a second example of a liquid crystal display device used as a stereoscopic image display device manufactured by the manufacturing method of the present invention and its use. In this example, the stereoscopic image display device 2 〇〇b, in place of the light source side polarizing plate 31, the liquid crystal panel 40, and the viewing side polarizing plate 3, has a light source side polarizing plate 31b, a liquid crystal panel 40b, and a viewing side polarizing plate 3〇b. The point which has the second retardation film 2〇b instead of the second retardation film 20 is different from that of the stereoscopic image display apparatus 200 of the first example, and the other points are common. The light source side polarizing plate 31b, the liquid crystal panel 40b, and the viewing side polarizing plate 3b have a configuration in which a linearly polarized light in the direction of the arrow Awb is emitted, and the second retardation film 2b is delayed in the vertical direction indicated by the arrow eight (10). The car is by. Further, the polarizing glasses 300b, in place of the 1/4 wavelength plate 32 〇, have a point of the 1/4 wavelength plate 32 0b, and have a linear polarizing plate 330 b instead of the linear polarizing plate 33 ,, and the polarizing glasses 3 of the first example. 〇〇Different, other points are common to 37 201248244. The quarter-wave plate 32 0b has a slow phase axis (that is, a horizontal direction) having a slow phase axis, and a linear polarizing plate 33, as indicated by an arrow A32eb, for the retardation axis of the second retardation film 20 of the stereoscopic image display device. 〇b, as indicated by the arrow A33〇b, has a polarization transmission axis parallel to the polarization transmission axis of the viewing-side polarizing plate 30b of the stereoscopic image display device 200b. The light that has passed through the light source side polarizing plate 31b, the liquid crystal panel 40b, and the viewing side polarizing plate 3Ob is linearly polarized and emitted. Since the transmission axis of the viewing side polarizing plate is inclined in the direction indicated by the arrow Am, the polarization direction of the light emitted from the viewing side polarizing plate 3 is changed to the direction indicated by the arrow. The retardation axis of the second retardation film 20b is indicated by an arrow A!!()b, and the polarization transmission axis of the viewing-side polarizing plate 30b is 45. The linearly polarized light emitted from the viewing-side polarizing plate 30b is converted into circularly polarized light having a rotational direction indicated by an arrow Am by penetrating the second retardation film 20b. Among the circularly polarized lights emitted from the second retardation film 20b, 'the light that penetrates the anisotropic region u' is converted into a circularly polarized light having an inverted rotation direction as indicated by an arrow Am. On the other hand, the 'isotropic region 12' The in-plane phase difference is zero, and therefore, the light that penetrates the isotropic region 12 among the circularly polarized lights emitted from the second retardation film 20b is 'as indicated by the arrow An2' to have the same rotational direction as before the penetration. The circular polarized light is emitted. The light R emitted from the anisotropic region 11 enters the portion of the right eye of the corresponding polarizing glasses 300b and penetrates the 1/2 wavelength plate 310, and the light R is converted into an arrow A310, and has a reverse rotation direction. Circularly polarized, incident on the 1/4 wavelength plate 320b. The light penetrating the quarter-wavelength plate 320b is converted into a linearly polarized light having a polarization axis in the same direction as the arrow A^Db, and therefore, it can penetrate 38 201248244 linear polarizing plate 330b. Therefore, the light R penetrating the anisotropic region 11 can be visually recognized by the right eye of the user. On the other hand, when the light R' emitted from the anisotropic region 11 is incident on the portion of the left eye of the corresponding polarizing glasses 300b, the light R' does not change the polarized light incident on the 1/4 wavelength plate 320b. The light penetrating the quarter-wavelength plate 320b is converted into a linearly polarized light having a polarization axis in a direction perpendicular to the arrow A33〇b. Therefore, the linear polarizing plate 330b cannot be penetrated. Therefore, the light R penetrating the anisotropic region 11 cannot be visually recognized by the user's left eye. Further, when the light L' emitted from the isotropic region 12 is incident on the portion of the left eye of the corresponding polarizing glasses 300b, the light L does not change the polarization incident 丄/4 wavelength plate 320b. The light penetrating the quarter-wavelength plate 320b is converted into linearly polarized light having a polarization axis in the same direction as the arrow A33Db, and therefore, the linear polarizing plate 330b can be penetrated. Therefore, the light L penetrating the isotropic region 12 can be visually recognized by the user's left eye. On the other hand, when the light L emitted from the isotropic region 12 enters the portion of the right eye of the corresponding polarizing glasses 300b and penetrates the half-wavelength plate 310, the light L' is converted into a reverse rotation direction (ie, The circularly polarized light in the opposite direction to the arrow a31〇 is incident on the quarter-wavelength plate 320b. The light that has passed through the quarter-wavelength plate 320b is converted into a linearly polarized light having a polarization axis in the vertical direction of the arrow A33〇b, so that the linear polarizing plate 330b cannot be penetrated. Therefore, the light L' penetrating the isotropic region 12 cannot be visually recognized by the right eye of the user. Thus, the user sees the light penetrating the anisotropic region 11 in the right eye, and further, the light penetrating the isotropic region 12 is viewed by the left eye. Therefore, by displaying the image for the right eye in the liquid crystal cell corresponding to the anisotropic region 11, the left-view stereoscopic image is displayed in the liquid crystal cell corresponding to the isotropic region $12 at 39 201248244. At this time, due to the stereoscopic and the blouse, the user can display the 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 Therefore, it is possible to accurately align the positional region of the pixel 11 * the phase of the isotropic region 12 to be left. Therefore, the enamel of the volume image display device 20〇b can be improved. Fig. 22 is an exploded perspective view showing still another example of a liquid crystal display device used as a three-dimensional image display device manufactured by the manufacturing method of the present invention and a third example of its use. The configuration of the stereoscopic image display device 2〇〇c is the same as that of the stereoscopic image display device of the first example. However, the stereoscopic image display device 200c displays the left eye (four) image in the liquid crystal cell corresponding to the anisotropy region u, and displays the right eye in the liquid crystal cell corresponding to the isotropic region 12, in contrast to the first #J. The image used. Further, the polarized glasses 300c are replaced by the linear polarizing plate 330c instead of the linear polarizing plate 33c, and the first! For example, polarized glasses 3 are common to other points. The 1⁄4 wavelength plate 320 is as indicated by an arrow a32. As shown in the figure, the linear phase polarizer 330c has a slow axis opposite to the slow axis of the second retardation film 20 of the stereoscopic image display device, and has a pair of stereoscopic image display devices 200c as indicated by an arrow Aa. The polarized light of the viewing side polarizing plate 30 penetrates the axis in the direction orthogonal to the axis (ie, the 'horizontal direction'). The light 'passing through the light source side polarizing plate 31, the liquid crystal panel 40, and the viewing side polarizing plate 30 is linearly polarized. Since the transmission axis of the viewing side polarizing plate is in the vertical direction as indicated by the arrow Aw, the polarization direction of the light emitted from the viewing side polarizing plate 3〇 is perpendicular to the direction indicated by the arrow A" "2nd phase 40 201248244 Since the retardation axis of the retardation film 20 is in the direction of the angle of 45° with respect to the polarization transmission axis of the viewing-side polarizing plate 30 as indicated by the arrow A", the linearly polarized light emitted from the viewing-side polarizing plate 30 is borrowed. The circularly polarized light is converted into a rotation direction indicated by an arrow by the second retardation film 2A. Among the circularly polarized lights emitted from the second retardation film 20, the light that has passed through the anisotropic region u is converted into a circularly polarized light having an inverted rotation direction as indicated by an arrow Auk. On the other hand, since the in-plane phase difference of the isotropic region 12 is zero, the light that penetrates the isotropic region 12 among the circularly polarized lights emitted from the second retardation film 20 is indicated by an arrow Auu. A circularly polarized light having the same direction of rotation as before the penetration is emitted. The light L emitted from the anisotropic region 11 is incident on the portion of the left eye corresponding to the polarizing glasses 300c, and the light L is incident on the quarter-wavelength plate 320 without changing the polarization. The light that penetrates the quarter-wavelength plate 320 is converted into an arrow Α 33β. The same direction has linear polarization of the polarization axis, and therefore, the linear polarizing plate 330c can be penetrated. Therefore, the light that penetrates the anisotropic region [ can be visually recognized by the user's left eye. On the other hand, the light L emitted from the anisotropic region enters the right eye portion of the corresponding polarizing glasses 300c, and passes through the ι/2 wavelength plate 31〇, and the light L is converted into a reverse rotation direction (ie, The circularly polarized light of the direction opposite to the arrow A3i()c is incident on the quarter-wavelength plate 32A. The light that penetrates the quarter-wavelength plate 32 ’ is transformed into the arrow A33(). The linearly polarized light having the polarization axis in the vertical direction 'hence' cannot penetrate the linear polarizing plate 33〇c. Therefore, the light L that penetrates the anisotropic region 11 cannot be visually recognized by the right eye of the user. Further, the light R emitted from the isotropic region 12 enters the portion of the right eye of the corresponding polarized light 41 201248244 glasses 300c and penetrates the 1/2 wavelength plate 310, and the light r is converted into an arrow as indicated by the arrow Asuc. The circularly polarized light in the direction of rotation is incident on the quarter-wavelength plate 320. The light penetrating the quarter-wavelength plate 320 is converted into a linearly polarized light having a polarization axis in the same direction as the arrow A33^, and therefore, the linear polarizing plate 330c can be penetrated. Therefore, the light R penetrating the isotropic region 12 can be visually recognized by the user's right eye. On the other hand, when the light R emitted from the isotropic region 12 is incident on the portion of the left eye of the corresponding polarizing glasses 300c, the light R is incident on the j /4 wavelength plate 320 without changing the polarization. The light that has penetrated the quarter-wavelength plate 320 is converted into a linearly polarized light having a polarization axis in a direction perpendicular to the arrow, and therefore, the linear polarizing plate 330c cannot be penetrated. Therefore, the light R penetrating the isotropic region 12 cannot be visually recognized by the user's left eye. Thus, the user views the light that penetrates the anisotropic region 11 with the left eye, and further sees the light that penetrates the isotropic region 12 as viewed by the right eye. Therefore, by displaying the image for the left eye in the liquid crystal cell corresponding to the anisotropy region 11, the image for the right eye is displayed in the liquid crystal cell corresponding to the isotropic region 12, and the user can view the stereoscopic image. At this time, since the stereoscopic image display device 2〇〇c has the first retardation film 10, the phase difference between the anisotropic region 11 and the isotropic region 12 can be accurately aligned with the position of the pixel. Therefore, the image quality of the stereoscopic image display device 200c can be improved. Further, the above-described three-dimensional image display devices 2〇〇, 2〇〇b, and 2〇〇c may be further modified. For example, the order of the second retardation film 2A and the i-th phase difference film 10 may be alternated, and the second retardation film 2 may be disposed on the viewing side of the second-order phase difference film 10. 42 201248244 3 « In addition, for example, the stereoscopic image display device 2〇〇, 2〇〇b, and 200=° can also be placed with an anti-reflection film, an anti-glare film, an anti-glare film, a hard coat film, and a brightness enhancement film. Layer 'adhesive layer, hard coat layer, anti-reflective film, protective layer, etc. Furthermore, the right eye portion of the polarized glasses 300, 300b, and 300c may be configured as a "left eye knife", and the image of the liquid crystal cell corresponding to the anisotropic region u and the image of the liquid crystal cell of the isotropic region 12 may be alternately imaged.

Corona discharge treatment and electropolymerization treatment are preferred from the point of treatment efficiency, and krypton corona is particularly preferable. The treatment of the drug may, for example, be immersed in an aqueous solution of an oxidizing agent such as concentrated sulfuric acid in a dichromate removal solution. After that, it is fully washed with water. When it is immersed in the state of immersion, there is 纟', but if it is immersed for a long time, there is a case where the surface is dissolved or the transparency is lowered.

The glass transition temperature of the resin component of the composition for a mask is usually 80 C or more, preferably i 〇〇 c or more, and usually 4 〇〇 ° C or less, preferably 350 C or less. By setting the glass transition temperature to 8 Å or more, the heat of the mask layer can be improved, for example, deformation of the mask layer during heating of the liquid crystal resin layer can be prevented. Further, the glass transition temperature is set to a paste. c Hereinafter, the composition of the mask can be easily printed by improving the solubility of the resin. When the glass transition temperature of the resin component changes between the state before printing and the state after the formation of the mask layer, it is preferable that the glass transition temperature is in the above range in the state after the formation of the mask layer.

[Coating of Composition for Forming Liquid Crystal Layer] The method of applying the composition for forming a liquid crystal layer may, for example, be a reverse gravure coating method, a direct gravure coating method, a die coating method, a wire bar coating method, or the like. Methods. A liquid crystal resin layer in an uncured state is formed by applying a composition for forming a liquid crystal layer on the surface of the base film. The composition for forming a liquid crystal layer can be directly applied to the surface of the base film, or can be indirectly applied to the surface of the base film via, for example, an alignment film. By using the alignment film, the liquid crystal compound can be easily aligned in the liquid crystal resin layer. The alignment film may, for example, be cellulose, decane coupling agent, polyimine, polyamine, polyvinyl alcohol, epoxy acrylate, sterol oligomer, polyacrylonitrile, phenol resin, polyoxazole, cyclization Polyisoprene and the like. These may be used singly or in combination of two or more kinds in any ratio. The thickness of the alignment film may be as large as 0. 001 " m or more as long as it is a desired uniformity of alignment uniformity of the liquid crystal resin layer. 〇1 " m or more preferably 5 / z The following is better than ra, preferably less than 2 ym. Further, for example, a photo-alignment film and a polarized light can be used as shown in, for example, Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The liver method aligns the liquid crystal compound. Further, the liquid crystal compound may be aligned by means other than the above alignment film. For example, the surface of the base film may be subjected to an alignment treatment using a rubbing film without using an alignment film. Usually, the conveying direction of the base film is parallel to the rubbing direction. The formation of the alignment film described above is performed on the surface of the substrate film by a brushing step 55 201248244, which may be performed before, during and after the step of forming the mask layer, but in the liquid crystal coating step. The step forward behavior is good. [Alignment step] The above-described method for producing a film of the target film is preceded by the first step of hardening, and the step of aligning the liquid crystal compound of the liquid crystal tree can be carried out after the step of (4). The specific (four) of the alignment step may be, for example, an operation of heating the liquid crystal resin layer in an uncured state at a predetermined temperature in an oven. In the alignment step, the temperature of the coating layer is usually 4 〇〇c or more, preferably 50 C or more, and usually 200 ° C or less, preferably 140 t or less. In addition, the processing time of the heat treatment is usually! The second or more is preferably 5 seconds or more, and is usually 3 minutes or less in seconds or less. Thereby, the liquid crystal compound in the liquid crystal resin layer can be aligned. When the composition for forming a liquid crystal layer contains a solvent, the solvent is usually dried by the above heating, so that the solvent can be removed from the liquid crystal resin layer. When the alignment step is carried out by &, the drying step of usually drying the liquid crystal resin layer can be simultaneously advanced. Usually, the alignment axis of the liquid crystal resin layer is parallel to the direction of the brush, and the alignment axis becomes a slow phase axis.

[Orientation change step] The alignment change step after the first hardening step can be changed to what kind of alignment state is set according to the application. For example, the liquid crystal resin layer is heated to a transparent point of the liquid crystal layer formation composition by a heater. (N j point). Since the alignment of the molecules of the liquid crystal compound can be made disordered by this, the region of the uncured state of the liquid crystal resin layer becomes an isotropic phase. [Second Hardening Step] The second curing step of the method for producing the first retardation film described above can be carried out by irradiating ultraviolet rays. The irradiation time, the amount of irradiation, and the like of the outer line of f may be appropriately sighed according to the thickness of the liquid crystal layer forming composition and the liquid crystal resin layer. The irradiation 1 is usually 5 〇 mJ/cm 2 to 1 Å. . . Further, the irradiation of the outer and outer lines can be carried out, for example, in an inert gas such as nitrogen or chlorine, or in the air. At the time of irradiation, the liquid crystal resin layer in an uncured state may be maintained in a driving phase while being heated by a heater as necessary.

Furthermore, there is material continuity between the first "head difference film 1 specific area and the anomalous P7& therefore

The point where reflection or scattering does not occur due to the gap between the regions is optically flawed, and it does not occur that the mechanical strength between the regions is also advantageous. The thickness of the liquid crystal resin layer of the first retardation film is the same as the value of the refractive index anisotropy Δη of the liquid crystal compound of the composition for forming a liquid crystal layer, respectively. The region 41 and the anisotropic region 42 are set to have an appropriate thickness in a desired in-plane phase difference. In general, the thickness of the liquid crystal resin layer is in the range of 0.5" or more and 50 // in.
