Description

  Embodiments described herein relate generally to a liquid crystal shutter set for eyeglasses and a method for manufacturing the same.

  Liquid crystals that are widely put into practical use in display devices are also used as shutters that control light transmission and light blocking properties by using a function capable of controlling light transmission by electric signals.

  For example, in a stereoscopic vision system that has been put to practical use in fields such as entertainment, education, broadcasting, and medical care, left and right eye images corresponding to left and right eye parallax are time-divided into left and right eyes, respectively. Liquid crystal is used for the shutter glasses presented in (1).

  The liquid crystal shutter glasses have a pair of liquid crystal shutters for left eye and right eye. The outer shape of the liquid crystal shutter for the left eye and the outer shape of the liquid crystal shutter for the right eye are often similar to each other. For this reason, the right and left may be mistaken.

  In order to visually distinguish the front and back of the substrate, an identification mark is formed on the transparent substrate end surface adjacent to the transparent electrode formed on the transparent substrate of the liquid crystal cell, and the electrode and the identification mark are formed on the transparent substrate. A liquid crystal device having an asymmetric pattern is known.

  However, a technique for easily discriminating a pair of liquid crystal shutters having similar external shapes such as liquid crystal shutter glasses has not been known so far. In order to widely spread the stereoscopic system, it is indispensable to produce liquid crystal shutter glasses with high efficiency. For this purpose, it is easy to distinguish between the left eye liquid crystal shutter and the right eye liquid crystal shutter, It is necessary to improve productivity.

A first seal 152 is provided between the first substrate unit 110 and the second substrate unit 120 so as to surround the first liquid crystal layer 151.

  As shown in FIGS. 3B and 4B, the third substrate unit 130 includes a third substrate 131, a third electrode 132 provided on the main surface of the third substrate 131, and a third substrate. 131 has a third optical film 135 provided on the side opposite to the third electrode 132.

  As shown in FIG. 4B, the third substrate unit 130 may further include a third alignment film 133 provided on the third electrode 132. In addition, the fourth substrate unit 140 may further include a fourth alignment film 143 provided on the fourth electrode 142.

  A second liquid crystal layer 161 is provided between the third substrate unit 130 and the fourth substrate unit 140 (that is, between the third alignment film 133 and the fourth alignment film 143). A second seal 162 is provided between the third substrate unit 130 and the fourth substrate unit 140 so as to surround the second liquid crystal layer 161.

  The first, second, third, and fourth optical films 115, 125, 135, and 145 may include a biaxial optical film, an optical film having negative optical anisotropy, and the like. The first, second, third, and fourth optical films 115, 125, 135, and 145 are attached to the first, second, third, and fourth substrates 111, 121, 131, and 141, respectively, with an adhesive or the like. It is done.

  The first, second, third, and fourth substrates 111, 121, 131, and 141 have a light-transmitting property with respect to visible light that is a target of light transmission and light shielding operations in the liquid crystal shutter set 10 for glasses. Or resin is used. The first, second, third, and fourth electrodes 112, 122, 132, and 142 are made of a transparent conductive film that is transparent to visible light, such as ITO (Indium Tin Oxide) or ZnO. Can be used.

  The first liquid crystal layer 151 and the second liquid crystal layer 161 can include, for example, an OCB (Optically Compensated Bend) type liquid crystal layer to which a π cell (spray alignment cell) is applied. In the OCB type liquid crystal layer, a high-speed response suitable for a liquid crystal shutter can be obtained by utilizing the bend alignment of the liquid crystal.

  In this case, as shown in FIGS. 3A and 3B, the liquid crystal alignment direction 111a on the first substrate 111 and the liquid crystal alignment direction 121a on the second substrate 121 are parallel to each other. . The liquid crystal alignment direction 111a and the liquid crystal alignment direction 121a are, for example, the rubbing directions of the first alignment film 113 and the second alignment film 123, respectively.

  Moreover, the optical axis 115a of the 1st optical film 115 is a horizontal direction, for example. And the optical axis 125a of the 2nd optical film 125 is a perpendicular direction, for example.

  The liquid crystal alignment direction 131a on the third substrate 131 and the liquid crystal alignment direction 141a on the fourth substrate 141 are parallel to each other. The liquid crystal alignment direction 131a and the liquid crystal alignment direction 141a are, for example, the rubbing directions of the third alignment film 133 and the fourth alignment film 143, respectively.

  Moreover, the optical axis 135a of the 3rd optical film 135 is a horizontal direction, for example. And the optical axis 145a of the 4th optical film 145 is a perpendicular direction, for example.

  As shown in FIGS. 3A and 3B, the outer shape of the first liquid crystal shutter 101 and the outer shape of the second liquid crystal shutter 102 have a mirror-symmetrical relationship with each other. For this reason, the shape when the first liquid crystal shutter 101 is viewed from the direction of the first substrate unit 110 matches the shape when the second liquid crystal shutter 102 is viewed from the direction of the fourth substrate unit 140. For this reason, when the first liquid crystal shutter 101 and the second liquid crystal shutter 102 are incorporated in the holding unit 301 of the liquid crystal shutter glasses 20, it is easy to mistake the left and right. For example, if the front and back directions are reversed, there is a possibility that an error in setting the first liquid crystal shutter 101 designed for the left eye on the right frame 320 of the holding unit 301 may occur.

  Further, after the first substrate 111 and the second substrate 121 are opposed to each other and the first liquid crystal layer 151 is sealed therebetween, the first optical film 115 and the second substrate 121 are respectively formed on the first substrate 111 and the second substrate 121. In the step of affixing the optical film 125, a fourth optical film 145 that looks similar to the first optical film 115 is affixed to the first substrate 111, and a third optical film 135 that looks similar to the second optical film 125. There is a possibility that an error in pasting to the second substrate 121 occurs.

Thus, in the liquid crystal shutter set 10 for eyeglasses used for the liquid crystal shutter glasses 20, there is a possibility that the left and right liquid crystal shutters may be mixed. This problem has not been noticed conventionally.
That is, in a display using liquid crystal, a liquid crystal display panel is mounted on various electronic devices. At this time, for example, one liquid crystal display panel is mounted on the electronic device. For example, even when mounted on a plurality of liquid crystal display panels, for example, a plurality of liquid crystal display panels having the same outer shape and the same specifications are mounted on an electronic device. Alternatively, a plurality of liquid crystal display panels having different external shapes are mounted on an electronic device. For this reason, the defect which mounted the wrong liquid crystal display panel in an electronic device did not generate | occur | produce.

  On the other hand, in the liquid crystal shutter glasses 20, a pair of liquid crystal shutters corresponding to the left and right eyes and having similar outlines are used. In the pair of liquid crystal shutters, for example, a mirror-symmetric outer shape is applied to the left-eye liquid crystal shutter and the right-eye liquid crystal shutter. For this reason, when the front and back of one liquid crystal shutter are reversed, the outer shape of the other liquid crystal shutter overlaps.

As described above, it has been recognized as a new problem that the pair of liquid crystal shutters used for the liquid crystal shutter glasses 20 is difficult to distinguish between the left eye and the right eye. That is, in the liquid crystal shutter glasses 20, it has been found that errors in setting the right and left liquid crystal shutters in the left and right frames and mistakes in attaching an optical film to the substrate are likely to occur.
The configuration of the present embodiment is constructed by paying attention to the problem newly generated in the liquid crystal shutter glasses 20 as described above.

  That is, as illustrated in FIG. 1, in the liquid crystal shutter set for glasses 10 according to the present embodiment, the first intermediate portion 150 has an asymmetric portion with respect to the second intermediate portion 160, so that The occurrence of mistakes can be suppressed. Since the asymmetric part provided in the first intermediate part 150 has a relative relationship with the second intermediate part 160, the second intermediate part 160 has an asymmetric part with respect to the first intermediate part 150. You may have.

  In this specific example, the first intermediate portion 150 has an asymmetric portion with respect to the second intermediate portion 160, but at least one of the first substrate portion 110 and the second substrate portion 120 is the third intermediate portion 150. You may have an asymmetrical part with respect to at least any one of the board | substrate part 130 and the 4th board | substrate part 140. FIG. This example will be described later.

As illustrated in FIG. 1, in this specific example, the shape of the first seal 152 included in the first intermediate portion 150 is asymmetric with respect to the shape of the second seal 162 included in the second intermediate portion 160. Specifically, the position of the inlet (first inlet 152a) provided in the first seal 152 is asymmetric with the position of the inlet (second inlet 162a) provided in the second seal 162.
That is, the shape of the first seal 152 is asymmetric with the shape of the second seal 152.

  Thus, in this specific example, a portion asymmetric with the second liquid crystal shutter 102 provided in the first liquid crystal shutter 101 is an injection port formed by the first seal 152. The asymmetric part (injection port in this specific example) has a size that can be visually discriminated. Specifically, the size of the asymmetric part (injection port in this specific example) is 1.0 millimeter (mm) or more. Thereby, the position of the injection port can be easily discriminated visually, and mistakes can be easily prevented, thereby improving productivity. Furthermore, the size of the asymmetric part (injection port in this specific example) is more preferably 2.0 mm or more. This further facilitates visual discrimination. It should be noted that if the size of the injection port becomes too large, the thickness of the intermediate portion may be uneven. Therefore, the size of the injection port is preferably 5.0 mm or less.

  In the eyeglass liquid crystal shutter set 10 according to the present embodiment, the discrimination between the left eye liquid crystal shutter and the right eye liquid crystal shutter is performed based on the shape of the seal (for example, the position of the injection port). It is easier to see than an identification mark (for example, formed of a material used for an electrode) provided on the substrate.

  That is, the thickness of the first intermediate portion 150 and the second intermediate portion 160 provided between the first substrate portion 110 and the second substrate portion 120 is, for example, about 5 micrometers (μm) (that is, the thickness of the liquid crystal layer). It is a degree. On the other hand, the conductive film for electrodes provided on the substrate is often about 0.1 μm or less. In the liquid crystal shutter set 10 for spectacles according to the present embodiment, an intermediate portion (at least one of the first intermediate portion 150 and the second intermediate portion 160) that can be thickened is used as the left and right discrimination marks. Easy-to-see marks can be realized. And since there is no new material added by using a seal as an identification mark using such an intermediate part, productivity is also high.

  As described above, according to the liquid crystal shutter set for glasses 10 according to the present embodiment, it is easy to distinguish between the liquid crystal shutter for the left eye and the liquid crystal shutter for the right eye, and a high-productivity liquid crystal shutter set for glasses is provided. it can.

(Second Embodiment)
FIG. 5 is a schematic perspective view illustrating the outline of the configuration of the liquid crystal shutter set for glasses according to the second embodiment.
FIG. 6A and FIG. 6B are schematic cross-sectional views illustrating the configuration of the liquid crystal shutter set for glasses according to the second embodiment.
6A is a cross-sectional view taken along line A1-A2 of FIG. 5, and FIG. 6B is a cross-sectional view taken along line B1-B2 of FIG.

  As shown in FIG. 5, FIG. 6A and FIG. 6B, the liquid crystal shutter set 11 for glasses according to this embodiment also includes a first liquid crystal shutter 101 and a second liquid crystal shutter 102. In FIG. 5, the first seal 152 and the second seal 162 are omitted.

  In the liquid crystal shutter set 11 for glasses, the first intermediate portion 150 of the first liquid crystal shutter 101 further includes a first transfer conductive portion 153, and the second intermediate portion 160 of the second liquid crystal shutter 102 is the second intermediate portion 160. A transfer conductive portion 163 is further provided.

  In this specific example, the position of the first transfer conductive portion 153 is asymmetric with the position of the second transfer conductive portion 163. That is, in this specific example, the position of the first transfer conductive portion 153 included in the first intermediate portion 150 is asymmetric with respect to the position of the second transfer conductive portion 163 included in the second intermediate portion 160. Since the position of the first transfer conductive portion 153 is asymmetric with the position of the second transfer conductive portion 163 in this way, the first seal 152 and the second seal 162 may be symmetric with each other. Furthermore, the first seal 152 and the second seal 162 may be asymmetric with respect to each other.

  Since the first transfer conductive portion 153 and the second transfer conductive portion 163 are asymmetric with each other, it is easy to distinguish between the left-eye liquid crystal shutter and the right-eye liquid crystal shutter, and the high-productivity liquid crystal for glasses. A shutter set can be provided.

  As illustrated in FIG. 6A, for example, the second substrate portion 120 is provided with the connection terminal electrode 124, and the first electrode 112 of the first substrate portion 110 and the connection terminal electrode of the second substrate portion 120 are provided. The electrode 124 is electrically connected to the first transfer conductive portion 153. Thus, in the first liquid crystal shutter 101, the first liquid crystal shutter 101 operates by supplying an electric signal only to the second substrate portion 120 side, and electrical connection becomes easy. On the contrary, the connection terminal electrode is provided on the first substrate unit 110, and the second electrode 122 of the second substrate unit 120 and the connection terminal electrode of the first substrate unit 110 are connected by the first transfer conductive unit 153. It may be electrically connected.

  On the other hand, as illustrated in FIG. 6B, for example, the fourth substrate unit 140 is provided with the connection terminal electrode 144, and the third electrode 132 of the third substrate unit 130 and the fourth substrate unit 140 are connected to each other. The terminal electrode 144 is electrically connected by the second transfer conductive portion 163. Thereby, in the second liquid crystal shutter 102, the second liquid crystal shutter 102 operates by supplying an electric signal only to the fourth substrate portion 140 side, and electrical connection becomes easy. On the contrary, the connection terminal electrode is provided on the third substrate portion 130, and the fourth electrode 142 of the fourth substrate portion 140 and the connection terminal electrode of the third substrate portion 130 are formed by the second transfer conductive portion 163. It may be electrically connected.

  As described above, the first intermediate portion 150 is a first conductive member (first transfer conductive member) that electrically connects the conductive film provided on the first substrate unit 110 and the conductive film provided on the second substrate unit 120. Part 153), and the second intermediate part 160 is a second conductive member (electrically connecting a conductive film provided on the third substrate part 130 and a conductive film provided on the fourth substrate part 140). And / or the second transfer conductive portion 163).

  Then, in the first transfer conductive portion 153 and the second transfer conductive portion 163 that transfer the electrical connection between the substrate portions, a liquid crystal shutter for the left eye (for example, the first liquid crystal shutter) is applied by applying an asymmetric relationship to each other. 101) and the right-eye liquid crystal shutter (second liquid crystal shutter 102) can be easily distinguished, and a liquid crystal shutter set for eyeglasses with high productivity can be provided.

  The first transfer conductive portion 153 and the second transfer conductive portion 163 have such a size that their presence positions can be visually determined. Specifically, the size of at least one of the first transfer conductive portion 153 and the second transfer conductive portion 163 is, for example, about 1.0 mm. As a result, the position of at least one of the first transfer conductive portion 153 and the second transfer conductive portion 163 can be easily discriminated visually, and mistakes can be easily prevented, thereby improving productivity. Note that the position of the transfer conductive portion itself can be sufficiently determined even if its size is smaller than 1.0 mm.

  For example, the transfer conductive portion can be provided in one of the first liquid crystal shutter 101 and the second liquid crystal shutter 102. This facilitates discrimination between the first liquid crystal shutter 101 and the second liquid crystal shutter 102.

  Further, when both the first transfer conductive portion 153 and the second transfer conductive portion 163 are provided, at least one of the position, shape, color, and size of the first transfer conductive portion 153 and the second transfer conductive portion 163 is provided. Is asymmetric.

  The first transfer conductive portion 153 can have a plurality of conductive portions. In such a case, the entirety of the plurality of conductive portions is regarded as the first transfer conductive portion 153. The second transfer conductive portion 163 can also have a plurality of conductive portions. In such a case, the entirety of the plurality of conductive portions is regarded as the second transfer conductive portion 163. Differences in the number and arrangement of the plurality of conductive portions provided are included in the difference in shape.

  As described above, the first transfer conductive portion 153 and the second transfer conductive portion 163 have a function of electrically connecting the electrodes and can function as an identification mark.

  That is, at least one of the first intermediate portion 150 and the second intermediate portion 160 further includes an intermediate portion identification mark (for example, the first transfer conductive portion 153 and the second transfer conductive portion 163). The first intermediate portion 150 and the second intermediate portion 160 are different.

  That is, the presence or absence of the intermediate part identification mark is different between the first intermediate part 150 and the second intermediate part 160, and the position of the intermediate part identification mark is asymmetric between the first intermediate part 150 and the second intermediate part 160.

  That is, at least one of the first intermediate portion 150 and the second intermediate portion 160 further includes an intermediate portion identification mark. The intermediate part identification mark is different between the first intermediate part 150 and the second intermediate part 160.

  As described above, the presence or absence of the intermediate part identification mark is different between the first intermediate part 150 and the second intermediate part 160, and the position of the intermediate part identification mark is between the first intermediate part 150 and the second intermediate part 160.

(Fourth embodiment)
FIG. 8 is a schematic perspective view illustrating the outline of the configuration of the liquid crystal shutter set for glasses according to the fourth embodiment.
As shown in FIG. 8, the liquid crystal shutter set 13 for glasses according to the present embodiment also includes a first liquid crystal shutter 101 and a second liquid crystal shutter 102. In FIG. 8, the first seal 152 and the second seal 162 are omitted.

  In the liquid crystal shutter set 13 for glasses, a substrate part identification mark is provided. Specifically, the first liquid crystal shutter 101 is provided with a first substrate portion identification mark 118, and the second liquid crystal shutter 102 is provided with a second substrate portion identification mark 138.

In this specific example, the first substrate portion identification mark 118 is an asymmetric portion with respect to the third substrate portion 130 in the first substrate portion 110.

  For the first substrate portion identification mark 118 and the second substrate portion identification mark 138, for example, a metal film that becomes a metal electrode electrically connected to the first electrode 112 and the third electrode 132, respectively, is processed into a predetermined pattern. Used.

  However, the present embodiment is not limited to this, and the first substrate portion identification mark 118 and the second substrate portion identification mark 138 are made of any material that can be discriminated by presence or absence of conductivity or insulation visually. Can do. In addition to the film formation and etching, an arbitrary method such as printing can be applied. For example, as the first substrate portion identification mark 118 and the second substrate portion identification mark 138, for example, portions processed by a laser or the like on each of the first substrate 111 and the third substrate 131 may be applied.

  Thus, in the liquid crystal shutter set 13 for glasses according to the present embodiment, at least one of the first substrate unit 110 and the second substrate unit 120 is at least one of the third substrate unit 130 and the fourth substrate unit 140. By having an asymmetric part, it is easy to distinguish between the left-eye liquid crystal shutter and the right-eye liquid crystal shutter, and a highly productive liquid crystal shutter set for glasses can be provided.

  For example, the first substrate unit 110 includes a first electrode 112 provided on a first main surface facing the second substrate unit 120, and the second substrate unit 120 is a second electrode facing the first substrate unit 110. The third substrate unit 130 includes the second electrode 122 provided on the main surface, and the third substrate unit 130 includes the third electrode 132 provided on the third main surface facing the fourth substrate unit 140. Has a fourth electrode 142 provided on the fourth main surface facing the third substrate portion 130, and the shape of at least one of the first electrode 112 and the second electrode 122 is the third electrode 132 and The shape of the fourth electrode 142 may be asymmetric with respect to at least one of the shapes.

  In addition, at least one of the first substrate unit 110, the second substrate unit 120, the third substrate unit 130, and the fourth substrate unit 140 has a substrate unit identification mark (a first substrate unit identification mark 118 and a second substrate unit identification mark). 138), and the substrate part identification mark can be different between the first liquid crystal shutter 101 and the second liquid crystal shutter 102.

  The presence or absence of the substrate part identification mark is different between the first liquid crystal shutter 101 and the second liquid crystal shutter 102, and the position of the substrate part identification mark is asymmetric between the first liquid crystal shutter 101 and the second liquid crystal shutter 102. The shape of the substrate portion identification mark is asymmetric between the first liquid crystal shutter 101 and the second liquid crystal shutter 102, and the color of the substrate portion identification mark is different between the first liquid crystal shutter 101 and the second liquid crystal shutter 102, and The size of the substrate part identification mark can be at least one of the first liquid crystal shutter 101 and the second liquid crystal shutter 102 different. The above-described shape of the substrate part identification mark can include the number of independent substrate part submarks included in the substrate part identification mark.

  In addition, at least one of the first substrate 111 and the second substrate 121 may have an asymmetric portion with respect to at least one of the third substrate 131 and the fourth substrate 141. In this case, for example, the outer shape of the first liquid crystal shutter 101 and the outer shape of the second liquid crystal shutter 102 are not mirror-symmetric with each other. Thereby, the left and right can be determined. In this way, when the outer shape of the first liquid crystal shutter 101 and the outer shape of the second liquid crystal shutter 102 are not mirror-symmetrical, the first liquid crystal shutter 101 and the second liquid crystal shutter 20 are attached to the frame of the liquid crystal shutter glasses 20 and the like. A design adapted to the external shape of the liquid crystal shutter 102 is applied.

  As described above, at least one of the first substrate unit 110 and the second substrate unit 120 has a portion that is asymmetric with respect to at least one of the third substrate unit 130 and the fourth substrate unit 140. It becomes easy to distinguish between the liquid crystal shutter and the right-eye liquid crystal shutter.

FIG. 9A, FIG. 9B, FIG. 10A, and FIG. 10B are schematic perspective views illustrating a method for manufacturing a spectacles liquid crystal shutter set according to the fifth embodiment.
As shown in FIG. 9A, in this manufacturing method, the first original substrate 110s and the second original substrate 120s are used. The first original substrate 110s becomes the first substrate 111 (first substrate unit 110) and the third substrate 131 (third substrate unit 130). That is, the first original substrate 110s is divided to form the first substrate 111 and the third substrate 131. Further, the second original substrate 120s becomes the second substrate 121 (second substrate unit 120) and the fourth substrate 141 (fourth substrate unit 140). That is, the second original substrate 120s is divided, and the second substrate 121 and the fourth substrate 141 are formed.

The first original substrate 110 s includes a plurality of first layers that are each a part of the first substrate unit 110 and a plurality of third layers that are each a part of the third substrate unit 130.
The first original substrate 110s may be divided to form the first substrate 111 and the fourth substrate 141. That is, the first original substrate 110s includes a plurality of first layers each serving as a part of the first substrate unit 110, and a plurality of layers serving as a part of one of the third substrate unit 130 and the fourth substrate unit 140, respectively. And a third layer. Hereinafter, a case where each of the plurality of third layers becomes a part of the third substrate unit 130 will be described.

On the other hand, the second original substrate 120 s has a plurality of second layers that are each part of the second substrate unit 120 and a plurality of fourth layers that are each part of the fourth substrate unit 140.
The second original substrate 120s may be divided to form the second substrate 121 and the third substrate 131. That is, the second original substrate 120s includes a plurality of second layers each serving as a part of the second substrate unit 120, and a plurality of second layers serving as the other part of the third substrate unit 130 and the fourth substrate unit 140, respectively. And a fourth layer. Hereinafter, the case where each of the plurality of fourth layers becomes a part of the fourth substrate unit 140 will be described.

  For example, the first layer may include the first electrode 112, and the first layer may further include the first alignment film 113. The third layer may include, for example, the third electrode 132, and the third layer may further include a third alignment film 133.

  The second layer includes, for example, the second electrode 122, and the second layer may further include the second alignment film 123. The fourth layer includes, for example, a fourth electrode 142, and the fourth layer may further include a fourth alignment film 143.

As shown in FIG. 9A, for example, the first layer and the third layer are alternately arranged. Further, for example, the second layer and the fourth layer are alternately arranged.
In this specific example, the first original substrate 110s is provided with two first layers and two third layers, but the number of first layers and the number of third layers are: Is optional. In this specific example, the first layer and the third layer are arranged in one direction (for example, the horizontal direction), but in one direction and another direction (for example, the vertical direction). You may line up.

  Similarly, in this specific example, the second original substrate 120s is provided with two second layers and two fourth layers, but the number of second layers, the number of fourth layers, Is optional. In this specific example, the second layer and the fourth layer are arranged in one direction (for example, the horizontal direction), but in one direction and another direction (for example, the vertical direction). You may line up.

  As shown in FIG. 9A, for example, a rubbing process is performed on the first original substrate 110s and the second original substrate 120s along the liquid crystal alignment directions 111a, 121a, 131a, and 141a.

  Thereafter, as shown in FIG. 9B, a first intermediate member is formed at a position corresponding to the first layer on the first main surface of the first original substrate 110s, and at a position corresponding to the third layer. A second intermediate member is formed. In this specific example, the first intermediate member is a resin that becomes the first seal 152. The second intermediate member is a resin that becomes the second seal 162.

  In the first intermediate member, a dividing portion of the first seal 152 is provided, and this dividing portion becomes the first injection port 152a. Further, the second intermediate member is provided with a divided portion of the second seal 162, and this divided portion serves as the second inlet 162a.

  And the position of the dividing part (first inlet 152a) of the first seal 152 and the position of the dividing part (second inlet 162a) of the second seal 162 are asymmetric with each other.

  That is, in the manufacturing method according to the present embodiment, the shape of the first intermediate member and the shape of the second intermediate member are asymmetric with each other.

  In the above description, a resin serving as a seal is provided on the first original substrate 110s. However, a resin serving as a seal may be provided on the second original substrate 120s.

  In this specific example, for example, the end mark 152d is provided together with the material used for at least one of the first intermediate member and the second intermediate member at the end of the first original substrate 110s. . The end mark 152d will be described later.

  Thereafter, the second main surface of the second original substrate 120s and the first main surface of the first original substrate 110s are opposed to each other, and the first liquid crystal layer and the first main surface are disposed between the first main surface and the second main surface. 2. Introduce a liquid crystal material to be a liquid crystal layer.

  In this specific example, as shown in FIG. 10A, the first original substrate 110s and the second original substrate 120s are assembled to face each other, and the first seal 152 of the first intermediate member and the second intermediate member are assembled. The second seal 162 is cured to bond the first original substrate 110s and the second original substrate 120s.

  The first original substrate 110s and the second original substrate 120s assembled in this way are arranged in a reduced-pressure atmosphere, for example, and the first note opened from the end portions of the first original substrate 110s and the second original substrate 120s. The inlet 152a and the second inlet 162a are immersed in a liquid crystal pot 170 containing a liquid crystal material. Thereafter, by returning the atmosphere to atmospheric pressure, a liquid crystal material is injected (introduced) between the first original substrate 110s and the second original substrate 120s.

  Then, after sealing the injection port, as shown in FIG. 10B, the first original substrate 110s and the second original substrate 120s are divided. That is, the first original substrate 110s and the second original substrate 120s are divided to form the first substrate unit 110, the second substrate unit 120, the third substrate unit 130, and the fourth substrate unit 140. Thereby, the first liquid crystal shutter 101 and the second liquid crystal shutter 102 are obtained.

  Thus, in the method for manufacturing the liquid crystal shutter set for glasses according to the present embodiment, the shape of the first intermediate member and the shape of the second intermediate member are asymmetric with each other. Thereby, the liquid crystal shutter for left eye and the liquid crystal shutter for right eye can be easily distinguished, and a liquid crystal shutter set for glasses can be manufactured with high productivity.

That is, in the present embodiment, the shape of the first film used for the first liquid crystal shutter 101 and the shape of the third film used for the second liquid crystal shutter 102 can be mirror-symmetric with each other. Similarly, the shape of the second film and the shape of the fourth film can be mirror-symmetric with each other.
At this time, the first liquid crystal shutter 101 and the second liquid crystal shutter 102 can be easily distinguished by making the shape of the first intermediate member and the shape of the second intermediate member asymmetric.

In the present embodiment, the difference between the shape of the first layer and the shape of the first intermediate member is different from the difference between the shape of the third layer and the shape of the second intermediate member.
For example, as illustrated in FIG. 9B, the difference between the shape of the first electrode 112 that is the first layer and the shape of the first seal 152 that is the first intermediate member is the third layer. The difference between the shape of the three electrodes 132 and the shape of the second seal 162 that is the second intermediate member is different. Thereby, even when the front and back are reversed, the first liquid crystal shutter 101 and the second liquid crystal shutter 102 can be easily distinguished.

  Furthermore, the outer shape of the substrate portion may be asymmetric when the first original substrate 110s and the second original substrate 120s are divided. This also facilitates discrimination between the first liquid crystal shutter 101 and the second liquid crystal shutter 102 even when the front and back sides are reversed.

  Thus, in the present embodiment, the difference between the shape of the first layer and the shape of the first intermediate member and the difference between the shape of the third layer and the shape of the second intermediate member are different from each other. And the shape of the second intermediate member are asymmetric with each other, and the outer shape of at least one of the first substrate unit 110 and the second substrate unit 120, and the third substrate unit 130 and the fourth substrate unit 140. And / or at least one of the outer shapes may be asymmetric with respect to each other.

  For example, the first intermediate member includes a first seal 152 disposed around the first liquid crystal layer 151, and the second intermediate member includes a second seal 162 disposed around the second liquid crystal layer 161, The pattern shape of the first seal 152 has a portion that is asymmetric with the pattern shape of the second seal 162. For example, this asymmetric portion can be a discontinuous portion of the first seal 152. This discontinuous portion functions as, for example, an injection port. That is, the asymmetric part is an injection port formed by the first seal 152 that introduces a liquid crystal material into a region surrounded by the first seal 152 on the first main surface of the first original substrate 110s. Can do.

  Note that the above may be considered that the pattern shape of the second seal 162 has an asymmetric portion with the pattern shape of the first seal 152. For example, this asymmetric portion is a discontinuous portion of the second seal 162. The asymmetrical portion may be an injection port formed by the second seal 162 that introduces a liquid crystal material into a region surrounded by the second seal 162 on the first main surface of the first original substrate 110s. It can be.

  Further, as already described, the seal pattern may be formed on the second original substrate 120s. In this case, the pattern shape of the first seal 152 is a portion asymmetric with the pattern shape of the second seal 162. Have.

  When the injection port is provided at an asymmetric position between the first liquid crystal shutter 101 and the second liquid crystal shutter 102, liquid crystal injection is performed by optimizing the relationship between the injection port and the orientation direction (for example, the rubbing direction). You can save time.

  That is, the manufacturing method according to the present embodiment further includes a step for aligning liquid crystal molecules of the liquid crystal material on the first main surface before the step of forming the first intermediate member and forming the second intermediate member. be able to. The first intermediate member includes a first seal 152 disposed around the first liquid crystal layer 151, and the second intermediate member includes a second seal 162 disposed around the second liquid crystal layer 161. The pattern shape of the first seal 152 has a portion (for example, an inlet) that is asymmetric with the pattern shape of the second seal 162. The asymmetric part (for example, the injection port) is formed by the first seal 152 that introduces the liquid crystal material into the region surrounded by the first seal 152 on the first main surface of the first original substrate 110s. A direction from the center of the region toward the position where the injection port is provided is a direction along the major axis direction of the liquid crystal molecules (that is, for example, the rubbing direction) (for example, a substantially parallel direction). it can. Thereby, injection | pouring time can be shortened and productivity improves more.

  In this specific example, since the position of the inlet is asymmetric between the first liquid crystal shutter 101 and the second liquid crystal shutter 102, the front and back of the set of the first liquid crystal shutter 101 and the second liquid crystal shutter 102 are reversed. The position of the inlet after inversion changes from the position of the inlet before inversion.

  For example, if the front and back of the set of the first liquid crystal shutter 101 and the second liquid crystal shutter 102 are reversed with respect to the state illustrated in FIG. 10A, the inlet is displaced from the position of the liquid crystal pot 170. Proper injection will not be performed. As described above, the first liquid crystal shutter 101 and the second liquid crystal are not set on the liquid crystal pot 170 by mistakenly inverting the front and back at the time of injection. In combination with the shutter 102, it is desirable to provide front and back (for example, left and right) marks.

  For example, as illustrated in FIG. 9B, a mark (end mark 152d) can be formed on one end portion of the first original substrate 110s with a material that serves as a seal. As a result, as shown in FIG. 10A, when the combination of the first liquid crystal shutter 101 and the second liquid crystal shutter 102 is set with the correct front and back arrangement, the formed end mark 152d has one end mark 152d. Located in. When the front and back are reversed and set incorrectly, the formed end mark 152d is positioned at the other end.

  Since the mark by the intermediate member such as a seal is more conspicuous than the mark provided on the substrate, it is possible to effectively suppress the wrong setting of the combination of the first liquid crystal shutter 101 and the second liquid crystal shutter 102.

  In this embodiment, a transfer conductive part may be used as the intermediate member. That is, the first intermediate member may include a first conductive member (first transfer conductive portion 153), and the second intermediate member may include a second conductive member (second transfer conductive portion 163). The pattern shape of the first conductive member may have a portion that is asymmetric with the pattern shape of the second conductive member.

  Further, as the intermediate member, a material used for the sealing material or a material used for the transfer conductive portion may be used to form an independent mark (for example, the end mark 152d) different from the seal or the transfer.

  Also in such a case, the first liquid crystal shutter 101 is made asymmetric with the shape of the first intermediate member included in the first liquid crystal shutter 101 and the shape of the second intermediate member included in the second liquid crystal shutter 102. 101 is easily distinguished from the second liquid crystal shutter 102, and a liquid crystal shutter set for glasses can be manufactured with high productivity.

  In the present embodiment, the shape of the first layer and the shape of the third layer are set differently. For example, the plurality of first layers include a plurality of first electrodes 112 for applying a voltage to the first liquid crystal layer 151, and the plurality of third layers are a plurality of for applying a voltage to the second liquid crystal layer 161. The pattern shape of each of the plurality of first electrodes 112 may include a portion that is asymmetric with the pattern shape of each of the plurality of third electrodes 132.

Moreover, the manufacturing method according to the present embodiment can further include a step of forming the first to fourth layers.
That is, this manufacturing method further includes a step of forming a plurality of first layers and a plurality of third layers before the step of forming the first intermediate member and forming the second intermediate member. The formation of the plurality of first layers includes a step of forming the plurality of first electrodes 112 for applying a voltage to the first liquid crystal layer 151, and the formation of the plurality of third layers includes the second liquid crystal layer 161. Forming a plurality of third electrodes 132 for applying a voltage to the first electrode 132. At this time, the step of forming the plurality of first electrodes 112 may include a step of forming the first substrate portion identification mark 118 using a material that becomes the plurality of first electrodes 112.

In addition, the step of forming the plurality of third electrodes 132 can include the step of forming the second substrate portion identification mark 138 using a material that becomes the plurality of third electrodes 132.
The position of the first substrate portion identification mark 118 is asymmetric with the second substrate portion identification mark 138, and the shape of the first substrate portion identification mark 118 is asymmetric with the second substrate portion identification mark 123. The color of the substrate portion identification mark 118 is different from that of the second substrate portion identification mark 123, and the size of the first substrate portion identification mark 118 is different from that of the second substrate portion identification mark 123.

  In addition, the manufacturing method according to the present embodiment includes a step of forming the first intermediate member and the second intermediate member before the step of forming the plurality of first layers and the plurality of third layers. Further, the formation of the plurality of first layers may include a step of forming a first layer identification mark (for example, the first substrate portion identification mark 118).

  The formation of the plurality of third layers can include a step of forming a third layer identification mark (for example, the second substrate portion identification mark 138). The position of the first layer identification mark is asymmetric with the third layer identification mark, the shape of the first layer identification mark is asymmetric with the third layer identification mark, and the color of the first layer identification mark is It is different from the three-layer identification mark, and the size of the first layer identification mark is at least either different from the third-layer identification mark.

  The liquid crystal shutter set for glasses according to the embodiment includes a first liquid crystal shutter 101 and a second liquid crystal shutter 102, and an identification mark is incorporated in at least one of the first liquid crystal shutter 101 and the second liquid crystal shutter 102. . This identification mark has an asymmetric relationship between the first liquid crystal shutter 101 and the second liquid crystal shutter 102 in at least one of the relationship among position, presence / absence, shape (including the number), and size. This facilitates discrimination between the first liquid crystal shutter 101 and the second liquid crystal shutter 102.

  For example, each of the shapes of the first liquid crystal shutter 101 and the second liquid crystal shutter 102 may have a shape that does not have an axis of symmetry. In this case, at least one of the relationship among the position, presence / absence, shape (including the number), and size of the identification mark is an asymmetric relationship between the first liquid crystal shutter 101 and the second liquid crystal shutter 102. is there. As a result, it is possible to determine the front and back as well as the first liquid crystal shutter 101 and the second liquid crystal shutter 102.

  Further, the identification mark may have an asymmetric relationship between the first liquid crystal shutter 101 and the second liquid crystal shutter 102 in any two or more of the relationship among the position, presence / absence, shape (including the number), and size. it can. This facilitates the discrimination between the first liquid crystal shutter 101 and the second liquid crystal shutter 102 and the discrimination between the front and back sides thereof.

  For example, in the case where each of the shapes of the first liquid crystal shutter 101 and the second liquid crystal shutter 102 has a symmetrical axis, the position, presence / absence, shape (including the number), and size of the identification mark At least any two of them have an asymmetric relationship between the first liquid crystal shutter 101 and the second liquid crystal shutter 102. As a result, it is possible to determine the front and back as well as the first liquid crystal shutter 101 and the second liquid crystal shutter 102.

  As described above, according to the embodiment, it is easy to distinguish between the liquid crystal shutter for the left eye and the liquid crystal shutter for the right eye, and a highly productive liquid crystal shutter set for eyeglasses and a method for manufacturing the same are provided.
