Description

This technology is about the production how line power sale-optical device stereoscopic display and multi-view display without using special glasses.

  2. Description of the Related Art Conventionally, an electro-optical device using image separation means such as a parallax barrier method or a lenticular method is known as an electro-optical device that realizes stereoscopic display or multi-viewpoint display without requiring special glasses. In the case of stereoscopic display, first, a right-eye image and a left-eye image corresponding to binocular parallax are prepared, and are alternately displayed in a vertical stripe shape, for example. Next, this display image is spatially separated by an image separation means such as a parallax barrier or a cylindrical lens having the same period as the image and guided to the right eye and the left eye of the observer. By selectively displaying different images corresponding to binocular parallax to the right eye and the left eye, it is possible to make the viewer stereoscopically view the display image. Further, in the case of multi-view display, multi-view display is realized by selectively guiding different images to the observers of the respective viewpoints by the image separation means based on the same principle.

  In these methods, the image separation means provided in the electro-optical device is generally composed of parts different from the panel which is the image display means, and is adhered to the surface portion of the panel. In order to realize a clear image display over the entire screen, it is important that the image separating means is adhered to the panel at a uniform interval. If the interval is not constant, it may cause deterioration in image quality such as display color unevenness and distortion.

As described above, when assembling the image separating means and the panel, there is a high quality requirement for making the distance between the panel and the image separating means uniform. Therefore, it is considered that a gap material is sandwiched between the image separation means and the panel so that the thickness (film thickness) of the adhesive film is kept constant when the image separation means and the panel are bonded. The aim is to facilitate the adjustment of the film thickness by setting the film thickness according to the height of the gap material. Up to now, a method has been adopted in which a gap material is placed outside the effective display area and bonded, or a method in which a gap material is arbitrarily mixed in the adhesive used for bonding and the entire adhesive is bonded with the adhesive. ing. Further, Patent Document 1 proposes a method of keeping a gap between a panel and the glass panel constant by arranging a plurality of gap members in advance on a glass panel provided with an image separation means.
JP 10-268232 A

  However, the above technique has the following problems. That is, when the gap material is installed and bonded outside the effective display area, it shrinks when the adhesive is cured, so that it is not guaranteed that the film thickness is constant within the effective display area. In addition, when a gap material is mixed in the adhesive, defects such as gap materials not being mixed uniformly in the adhesive or uneven application of the adhesive are likely to occur. Due to the defect, an agglomerated portion of the gap material is likely to occur after the adhesive is cured, and the agglomerated portion may cause display unevenness.

  Moreover, in the method described in the above-mentioned patent document, only the height of the gap material is mentioned, and the material and refractive index of the gap material are not mentioned. Further, although there is an example in which a gap material is arranged on the back surface of the image separating means, the configuration basically does not prevent the gap material from being arranged in the image display area. When a gap material is disposed in the image display area, if a gap material having a refractive index different from that of the image separation means is used, transmitted light is reduced, and the contrast and brightness are affected. Even if a gap material that takes into account the refractive index is used, the gap material becomes a scattering source and the scattered light increases, so that deterioration in quality such as display unevenness and distortion is inevitable.

This technique was made in view of such circumstances, and aims to provide a method of manufacturing to that electric optical device prevent distortion of display unevenness and image.

In order to solve the above problem, an electro-optical device manufacturing method according to an embodiment of the present technology includes a plurality of sub-pixels and a black matrix disposed between the sub-pixels, and displays a plurality of images on the same screen. The electro-optical panel and the light-shielding plate are arranged on one of an electro-optical panel, a plurality of openings, and a light-shielding portion that does not form the openings and spatially separates the plurality of images. A first step of fixing a gap material that maintains a constant gap with the plate using a first adhesive, and a surface on which the gap material of one of the electro-optic panel and the light shielding plate is fixed; A second step of applying a second adhesive having a viscosity lower than that of the first adhesive, and the electro-optic on a surface of the electro-optical panel and the light-shielding plate on which the gap member is fixed. The other of the panel and the light shielding plate The in opposition, and a third step of bonding the light shielding plate with these electro-optical panel.
According to this method, since the gap material is fixed by the first adhesive having a relatively higher viscosity than the second adhesive, the first adhesive is spread and spread for application of the second adhesive. It is possible to prevent the gap material from being displaced. Therefore, the application of the second adhesive is facilitated, and the process can be simplified. In addition, it is possible to reduce the incidence of defective products due to poor arrangement of the gap material. Therefore, the yield can be increased and the manufacturing cost of the electro-optical device can be reduced.
The electro-optical device of the present technology includes an electro-optical panel that displays a plurality of images on the same screen, an image separation unit that spatially separates the plurality of images, the electro-optical panel, and the image separation unit. And a gap member that keeps a constant distance between the electro-optical panel and the image separating means, and the electro-optical panel includes a plurality of sub-pixels and a black disposed between the sub-pixels. A matrix, and the image separation means is a light shielding plate comprising a plurality of openings and a light shielding part in which the plurality of openings are not formed, and the gap material is within the region of the light shielding part. there are, that provided in the two adjacent said opening overlaps the black matrix in a plane disposed equal distance position from the position.
According to this configuration, the gap material is provided at a position that is not an opening portion of the light shielding plate through which an image is transmitted and is not a sub-pixel region for displaying an image. Therefore, the gap material does not block the display image, and the display image is not adversely affected. Therefore, display unevenness and distortion caused by the gap material can be prevented, and a clear image can be expressed. Furthermore, since the gap material is disposed in the effective display area, it can be ensured that the distance between the electro-optical panel and the image separating means is constant in the effective display area.

In the present technology, it is preferable that the gap material is provided separately from the electro-optical panel and the image separation unit.
According to this configuration, the gap between the electro-optical panel and the image separating unit can be adjusted by changing the gap material. Therefore, it is easy to adjust the interval for design change and quality improvement according to the purpose. Further, by changing the gap material, it is possible to manufacture products with different designs from the same electro-optical panel and image separation means. Therefore, it becomes possible to manufacture a wide variety of products from a small amount of raw materials, and the manufacturing cost can be reduced. Furthermore, the position where the gap material is installed and the number of installation places can be easily changed. Therefore, design changes and quality adjustments for optimization can be easily performed.

In the present technology, it is preferable that the gap material is provided in a region overlapping with the intersection of the black matrix in the region of the light shielding portion.
According to this configuration, even if the gap material is installed at a position slightly deviated from the setting, the gap material is less likely to be installed at a position overlapping the sub-pixel. Therefore, the gap material can be easily installed, and the manufacturing process can be made more efficient and simplified. In addition, it is possible to reduce the incidence of defective products due to poor arrangement of the gap material. Therefore, the yield can be increased and the manufacturing cost can be reduced.

In the present technology, it is preferable that the electro-optical panel and the image separation unit are bonded via an adhesive layer, and the gap material has the same refractive index as that of the adhesive layer.
According to this configuration, light loss can be suppressed at the interface between the gap material and the adhesive layer. Therefore, display unevenness and image distortion can be prevented, and a clear image can be displayed.

In the present technology , the gap material may be black.
According to this configuration, the gap material shields light between the sub-pixels adjacent to the gap material. For this reason, it is possible to prevent light of different colors of adjacent sub-pixels from being mixed, and it is possible to display a clear image without color unevenness.

In the present technology , the gap material may be provided integrally with the electro-optical panel or the image separation unit.
According to this configuration, since the gap material does not move in the third step of bonding the image separating means and the electro-optical panel, a product in which the gap material is arranged at the designed position can be easily manufactured. Further, since the gap material does not move, the process of applying the adhesive for forming the adhesive layer is facilitated, and the efficiency of the process can be improved.

According to this configuration, it is possible to provide an electro-optical device that can prevent display unevenness and distortion and can express a clear image.

[First Embodiment]
Hereinafter, an electro-optical device and a method for manufacturing the electro-optical device according to the first embodiment of the present technology will be described with reference to FIGS. In all the drawings below, the film thicknesses and dimensional ratios of the constituent elements are appropriately changed in order to make the drawings easy to see.

  FIG. 1 shows an electro-optical device 1 according to this embodiment. FIG. 1A is a plan view of image separation means 2 constituting the electro-optical device 1. The image separating unit 2 is a light shielding plate provided with a plurality of openings 4 and a light shielding part 5 in which the plurality of openings 4 are not formed on the substrate 3. The openings 4 and the light-shielding portions 5 are regularly and alternately formed to form a striped pattern in a straight line in the vertical direction.

  FIG. 1B is a plan view of the electro-optical panel 6 constituting the electro-optical device 1. The electro-optical panel 6 includes a plurality of sub-pixels 7r, 7g, and 7b that are regularly and repeatedly arranged. The sub-pixel 7r is assigned a red color filter, 7g is assigned a green color, and 7b is assigned a blue color filter. Further, a black matrix 8 is provided between the sub-pixels, and a region having a constant width is formed in a lattice shape so as to surround the sub-pixels 7r, 7g, and 7b.

  FIG. 1C is a plan view of the electro-optical device 1. The electro-optical device 1 includes an image separating unit 2 and an electro-optical panel 6. The image separating means 2 is arranged so as to overlap the electro-optical panel 6 so that the stripe pattern formed by the opening 4 and the light shielding portion 5 is parallel to the long side direction of the sub-pixels 7r, 7g, 7b. Between the image separating means 2 and the electro-optical panel 6, a plurality of gap members 9 are provided for maintaining a constant gap (gap) between the image separating means 2 and the electro-optical panel 6. The gap material 9 is a position that overlaps the black matrix 8 in the area of the light-shielding portion 5 and is adjacent to the sub-pixels 7r, 7g, and 7b, and a central portion in the long side direction of the sub-pixels 7r, 7g, and 7b. It is provided at a position that is near.

  In this embodiment, a liquid crystal panel is used as the electro-optical panel 6, but a display panel other than the liquid crystal panel may be used as the electro-optical panel. As other display panels, self-luminous panels such as electroluminescence panels (EL panels) can be used in addition to non-luminous panels such as liquid crystal panels and electrophoresis panels. Further, although a parallax barrier type stripe barrier is used as the image separating means 2, a step barrier, a lenticular lens, or the like can also be used.

  Next, a method for manufacturing the electro-optical device 1 will be described. 2 to 4 are process diagrams of the electro-optical device manufacturing method according to the present embodiment. 2A to 4B, FIG. 2A is a plan view, and FIG. 2B is a cross-sectional view taken along the line IIb in FIG. 2A and a cross-sectional view corresponding to FIG. 2B. .

  First, the first step will be described. As shown in FIG. 2A, the gap material 9 is disposed at a predetermined position of the light shielding portion 5 and fixed with the first adhesive 10. A material having the same refractive index as that of the first adhesive 10 is preferably used for the gap material 9. As the 1st adhesive agent 10, even before it hardens | cures and adheres, the ultraviolet curable resin which has a viscosity high enough to fix the gap material 9 in the arrange | positioned position is used. When the gap material 9 is disposed using the first adhesive 10, the gap material 9 may be disposed on the first adhesive 10 after the first adhesive 10 is disposed at a predetermined position. Alternatively, the gap material 9 may be mixed in advance so as to be uniformly dispersed in the first adhesive 10, and the first adhesive 10 mixed with the gap material 9 may be disposed at a predetermined position. In the present embodiment, the gap material 9 is fixed by arranging the first adhesive 10 mixed with the gap material 9 at a predetermined position. After the arrangement, as shown in FIG. 2B, the first adhesive 10 swells at a predetermined position of the light shielding portion 5, and the gap material 9 is mixed with the first adhesive 10 and the first adhesive 10. Fixed in the same place.

  Next, the second step will be described. As shown in FIG. 3A, the second adhesive 11 is applied in a strip shape on the surface of the image separating means 2 on the side where the gap material 9 is disposed. As the second adhesive 11, an ultraviolet curable resin having a viscosity relatively lower than that of the first adhesive 10 is used. In this case, it is desirable that the first adhesive 10 and the second adhesive 11 are resins of the same or similar curing conditions. The second adhesive 11 preferably has the same refractive index as that of the gap material 9 and the first adhesive 10. The second adhesive 11 may be applied to the entire surface of the substrate 3, but it is more preferable to apply the second adhesive 11 without overlapping the first adhesive 10. After application, as shown in FIG. 3B, the gap material 9 is fixed in a state of being mixed in the first adhesive 10 without changing its position.

  Next, the third step will be described. As shown in FIG. 4A, an electro-optical panel including sub-pixels 7r, 7b, and 7g and a black matrix 8 is arranged on the surface of the image separating unit to which the second adhesive is applied, and is irradiated with ultraviolet rays. Glue. In the present embodiment, the viscosity of the first adhesive 10 that fixes the gap material 9 is relatively higher than the viscosity of the second adhesive 11. Therefore, even if the second adhesive 11 is spread and spread when the image separating means 2 and the electro-optical panel 6 are bonded, the first adhesive 10 is not swept away by the second adhesive 11, and the gap material 9 is allowed to pass through the predetermined amount. Fix in position. As a result, the gap material 9 is fixed at a predetermined position. As shown in FIG. 4B, the image separating unit 2 and the electro-optical panel 6 are bonded by an adhesive layer 13 including a first adhesive 10 and a second adhesive 11. Since the first adhesive 10 and the second adhesive 11 have the same refractive index as that of the gap material 9, the adhesive layer 13 also has the same refractive index as that of the gap material 9. The gap material 9 is provided at a position sandwiched between the light shielding portion 5 and the black matrix 8, and the interval 12 between the image separating means 2 and the electro-optical panel 6 becomes constant depending on the size of the gap material 9 sandwiched in each place. . Thus, the electro-optical device 1 is completed.

  According to the electro-optical device configured as described above, the gap member 9 is provided not at the opening 4 of the image separating means 2 through which an image is transmitted but at a position that is not the region of the sub-pixels 7r, 7g, and 7b that display the image. It has been. Therefore, the gap material 9 does not block the display image and does not adversely affect the display image. Therefore, display unevenness and distortion caused by the gap material 9 can be prevented, and a clear image can be expressed. Further, since the gap member 9 is disposed in the effective display area, it can be ensured that the distance between the electro-optical panel 6 and the image separating means 2 is constant even in the effective display area.

  In this embodiment, since the gap member 9 is provided separately from the electro-optical panel 6 and the image separating unit 2, the gap between the electro-optical panel 6 and the image separating unit 2 can be adjusted. It becomes possible by change. Therefore, it is easy to adjust the interval for design change and quality improvement according to the purpose. Further, by changing the gap material 9, it is possible to manufacture products with different spacing designs from the same electro-optical panel 6 and image separation means 2. Therefore, it becomes possible to manufacture a wide variety of products from a small amount of raw materials, and the manufacturing cost can be reduced. Furthermore, the position where the gap material 9 is installed and the number of installation places can be easily changed. Therefore, design changes and quality adjustments for optimization can be easily performed.

  Further, in this embodiment, since the gap material 9 has the same refractive index as that of the adhesive layer 13, light loss can be suppressed at the interface between the gap material 9 and the adhesive layer 13. Therefore, display unevenness and image distortion can be prevented, and a clear image can be displayed.

  Further, according to the method for manufacturing the electro-optical device 1 as described above, the gap material 9 is fixed by the first adhesive 10 having a relatively higher viscosity than the second adhesive 11, and thus the second adhesive. It is possible to prevent the position of the gap material 9 from being shifted due to the first adhesive 10 being spread due to the application of the agent 11. Therefore, the application of the second adhesive 11 becomes easy, and the process can be simplified. In addition, it is possible to reduce the incidence of defective products due to the poor placement of the gap material 9. Therefore, the yield can be increased and the manufacturing cost of the electro-optical device 1 can be reduced.

  In the present embodiment, the gap material 9 is provided in the region of the light shielding portion 5 and in a position overlapping the black matrix 8 in the vicinity of the central portion in the long side direction of the sub-pixels 7r, 7g, and 7b. However, it is more preferable that it is provided within the area of the light shielding portion 5 and at a position overlapping the intersection of the black matrix 8 in a plane. FIG. 5 is a plan view of the electro-optical device 14 in the case where the gap member 9 is provided at the intersection of the black matrix 8, and this figure corresponds to FIG. According to this configuration, even if the gap material 9 is installed at a position slightly deviated from the setting, the gap material 9 is less likely to be installed at a position overlapping the sub-pixel. That is, according to FIG. 4A, when the gap material 9 is slightly displaced in the horizontal direction when the gap material 9 is disposed or when the image separating means 2 and the electro-optical panel 6 are bonded, the gap material 9 is It will be arranged on the sub-pixel. However, since the gap material 9 is disposed at the intersection of the black matrix 8 in FIG. 5, even if it is slightly displaced in the horizontal direction, it does not deviate from the black matrix 8 and is not disposed on the sub-pixel. Accordingly, since some deviation is allowed, the gap material 9 can be easily installed, and the manufacturing process can be made more efficient and simplified. In addition, it is possible to reduce the incidence of defective products due to the poor placement of the gap material 9. Therefore, the yield can be increased and the manufacturing cost can be reduced.

  In this embodiment, the gap material 9 has the same refractive index as that of the adhesive layer 13, but the gap material 9 may be black. In this case, since the gap material 9 shields light of different colors emitted from adjacent sub-pixels, for example, the sub-pixels 7g and 7b, color mixture can be prevented and a clear image can be displayed.

[Second Embodiment]
Next, an electro-optical device and a method for manufacturing the electro-optical device according to the second embodiment of the present technology will be described with reference to FIGS. 6 and 7. 6A to 7A are plan views, and FIG. 6B is a cross-sectional view corresponding to FIG. The electro-optical device and the method of manufacturing the electro-optical device according to the present embodiment are partly in common with the first embodiment. The difference is that the gap material is provided integrally with the image separating means. Therefore, in this embodiment, the same code | symbol is attached | subjected about the component which is common in 1st Embodiment, and detailed description is abbreviate | omitted.

  FIG. 6 shows an image separation unit 22 constituting the electro-optical device 21. As shown in FIG. 6A, the image separating unit 22 is a light shielding plate provided with a plurality of openings 4 and a light shielding part 5 in which the plurality of openings 4 are not formed on the substrate 23. Further, a gap material 24 is formed integrally with the image separating means 22 at a predetermined position of the light shielding portion 5 provided on the substrate 23. As shown in FIG. 6B, the gap material 24 protrudes from the light shielding portion 5 and is formed with a uniform height 25. The shape of the gap member 24 is not particularly limited as long as a predetermined height can be realized. For example, a columnar shape, a conical shape, a hemispherical shape, or the like can be selected. The shape of the gap member 24 can be formed by employing a conventionally known method such as patterning and etching at a predetermined position using a photolithography method, for example.

  FIG. 7 shows an electro-optical device 21. The electro-optical device 21 includes an image separating unit 22 and an electro-optical panel 6. As shown in FIG. 7A, the gap member 24 is disposed at a position overlapping the black matrix 8 in a plan view. As shown in FIG. 7B, the image separating means 22 and the electro-optical panel 6 are bonded via an adhesive layer 26. The gap material 24 has the same refractive index as that of the adhesive layer 26. Further, the image separating means 22 and the electro-optical panel 6 are bonded at a constant interval equal to the height 25 of the gap member 24.

  According to the electro-optical device configured as described above, as in the first embodiment, the gap member 24 is not the opening 4 of the image separating unit 22 through which an image is transmitted, and is not a sub-pixel region for displaying an image. Is provided. Therefore, the gap member 24 does not block the display image and does not adversely affect the display image. Therefore, display unevenness and distortion caused by the gap material 24 can be prevented, and a clear image can be expressed. Furthermore, since the gap member 24 is disposed in the effective display area, it can be ensured that the distance between the electro-optical panel 6 and the image separating means 22 is constant even in the effective display area. Unlike the first embodiment, since the gap material 24 is formed integrally with the image separating means 22, there is no fear that the position of the gap material 24 is shifted in the third step. Therefore, a product in which the gap member 24 is arranged at a position as designed can be easily manufactured. Further, since the gap member 24 does not move, the process of applying the adhesive for forming the adhesive layer 26 becomes easy, and the process efficiency can be improved.

  In the present embodiment, since the gap material 24 has the same refractive index as that of the adhesive layer 26, light loss can be suppressed at the interface between the gap material 24 and the adhesive layer 26. Therefore, display unevenness and image distortion can be prevented, and a clear image can be displayed.

  In the present embodiment, the gap material 24 has the same refractive index as that of the adhesive layer 26, but the gap material 24 may be black. In this case, since the gap material 24 shields light of different colors emitted from adjacent sub-pixels, color mixing can be prevented and a clear image display can be performed.

  In the present embodiment, the gap material 24 is formed on the image separating unit 22, but it may be formed on the black matrix 8 on the electro-optical panel 6.
