Manufacturing device and manufacturing method of 3-dimensional liquid crystal display device

The present invention relates to a polarizing type three-dimensional liquid crystal display device manufacturing apparatus and a manufacturing method thereof, wherein a linearly polarized light emitted from a liquid crystal display panel is changed into a reverse rotation direction of a rotating direction by a phase difference plate provided on a liquid crystal display panel. Two circularly polarized lights are emitted, and one circularly polarized light is incident on the right eye, and the other circularly polarized light is incident on the left eye, so that the image of the right eye and the left eye is generated to generate a parallax for stereoscopic display.

In the three-dimensional liquid crystal display device of the polarized glasses method, as shown in FIG. 10, a phase difference plate 50 is provided on the front surface of the liquid crystal display panel 47. 11 is a flow chart for manufacturing the phase difference plate 50, FIG. 12 is a plan view of the liquid crystal display panel 47, FIG. 13 is a plan view of the phase difference plate 50, and FIGS. 14 and 15 are for making the liquid crystal display panel 47 and the phase difference. The board 50 is laminated to form a picture. This liquid crystal display panel 47 firstly arranges the polarizing plate 42 on the front surface of the backlight panel 41. Next, the array substrate 43 is disposed on the front surface of the polarizing plate 42, and the liquid crystal material 44 is sealed between the array substrate 43 and the color filter substrate 45 provided on the front surface of the array substrate 43. Then, a polarizing plate 46 is disposed on the front surface of the color filter substrate 45 to constitute a polarizing plate 46. The liquid crystal display panel 47 as shown in Fig. 12. As described above, since the polarizing plate 46 is provided on the outermost surface of the liquid crystal display panel 47, the light emitted from the liquid crystal display panel 47 becomes the linearly polarized light 61.

Next, the phase difference plate 50 will be described. As shown in Fig. 11, in the production of the phase difference plate 50, an alignment film is first applied onto a substrate and dried. Exposure is then performed by an exposure apparatus to align the coated and dried alignment film. Then, the liquid crystal was applied, dried, and UV-cured, whereby a phase difference plate 50 was produced. The phase difference plate 50 is designed such that the phase difference is a quarter wavelength of the light wavelength, and the optical axis of the phase difference plate 50 is disposed at an angle of 45 degrees with respect to the polarization axis of the polarizing plate 46. Before 47. Thereby, when the linearly polarized light 61 emitted from the liquid crystal display panel 47 passes through the phase difference plate 50, it is formed into circularly polarized light due to the birefringence effect.

Further, in the pixel of the liquid crystal display panel 47, the right-eye pixel line and the left-eye pixel line are alternately arranged for each line of scanning lines, and the right-eye pixel is formed for the right-eye pixel and the left-eye pixel is formed for the left eye. The parallax image is displayed as an image. Further, the phase difference plate 50 has two regions of the right-eye polarizing portion 48 and the left-eye polarizing portion 49 as shown in FIG. 13, for example, the optical axis of the right-eye polarizing portion 48 with respect to the polarizing plate 46. The polarization axis is formed at +45 degrees, and the optical axis of the left-eye polarizing portion 49 is designed to form an angle of -45 degrees with respect to the polarization axis of the polarizing plate 46. Further, as shown in FIG. 15, the right-eye pixel line of the liquid crystal display panel 47 and the right-eye polarizing unit 48 of the phase difference plate 50 are overlapped, and the left-eye pixel line of the liquid crystal display panel 47 and the phase difference plate 50 are provided. The liquid crystal display panel 47 and the phase difference plate are bonded to each other in such a manner that the left-eye polarizing portion 49 overlaps 50. As a result, the light passing through the phase difference plate 50 as shown in FIGS. 10(b) and 10(c) is, for example, the right-eye polarizing unit 48 becomes the right circularly polarized light 62, and the left-eye polarizing unit 49 becomes Left circular polarized light 63. In other words, the direction of the polarized light 62 emitted from the pixel for the right eye and the polarized light 63 emitted from the pixel for the left eye is a direction of reverse rotation.

On the other hand, in order to visually recognize these polarized lights, as shown in Fig. 10(a), the glasses 53 worn by the observer also have polarizing characteristics. A polarizing plate and a phase difference plate (1/4 wavelength plate) are disposed on the glasses 53, and the polarization characteristics are different depending on the right eye 51 and the left eye 52. For example, a polarizing plate and a quarter-wave plate are disposed on the right-eye 51 to change the right circularly polarized light into a linearly polarized light, and the polarizing plate is disposed in the left-eye 52 to change the left circularly polarized light into a linearly polarized light. 1/4 wavelength plate. When the viewer wearing the glasses 53 visually recognizes the liquid crystal display panel 47, the right circularly polarized light 62 emitted from the right-eye pixel is changed to linearly polarized light and then incident on the right-eye 51 of the glasses 53. The right eye of the observer, but the left circular polarized light 63 emitted from the pixel for the left eye does not pass through the right eye 51 of the eyeglasses 53. Further, the left circularly polarized light 63 emitted from the pixel for the left eye is converted into the left eye of the observer after the left eye 52 of the eyeglasses 53 is changed to be linearly polarized, but the right circularly polarized light 62 is emitted from the pixel for the right eye. 52 is not passed through the left eye of the eyeglasses 53. Thereby, the right eye can see the right eye image, that is, the right eye pixel, and the left eye can see the left eye image, that is, the left eye pixel set, thereby displaying the parallax on the liquid crystal display panel 47 as described above. The image, so the observer can view the stereo image.

In order to realize the phase difference plate as described above, various technical solutions have been proposed. First, Patent Document 1 discloses that plural numbers are arranged adjacently The sheet-like phase difference member has a retardation axis or a phase advancement axis of the adjacent sheet-like phase difference members facing each other in directions different from each other. The sheet-like phase difference member has a certain width, and is regularly arranged with phase difference regions composed of mutually different slow phase axes or phase advance axes. Further, the sheet-like phase difference member is designed such that the phase difference is a quarter wavelength of the light wavelength, and the slow phase axis or the phase advance axis is ± with respect to the polarization axis of the polarizing plate on the liquid crystal display panel. Designed in a 45 degree angle. Thereby, when the linearly polarized light emitted from the polarizing plate on the liquid crystal display panel passes through the sheet-like phase difference member, it changes to the right circular polarization and the left circular polarization. When the plurality of sheet-like phase difference members are bonded to the liquid crystal display panel, and the phase difference regions formed by mutually different slow phase axes or phase advance axes are displayed, the right eye and the left are alternately displayed for each scanning line in advance. When the scanning line of each line of the liquid crystal display panel formed by the image for the eye corresponds to each other, the polarization direction emitted from the pixel for the right eye and the polarization direction emitted from the pixel for the left eye are different from each other. Thereby, when the liquid crystal display panel is visually recognized by wearing the polarized glasses, the right eye can see the image for the right eye, and the left eye can see the image for the left eye, thereby enabling the image of the right eye and the left eye to be incident. Stereoscopic display is generated by generating parallax.

Further, Patent Document 2 discloses a phase difference plate in which a fine periodic structure is directly formed on a substrate, and the fine periodic structure alternately forms two regions in which the directions of the optical axes of the transmitted light are different from each other. This fine periodic structure utilizes a technique of arranging a plurality of flat plates having different refractive indices which are not birefringent characteristics at a period far smaller than the wavelength of light to cause birefringence characteristics. In addition, the direction of the optical axis can be arbitrarily determined by arranging the directions of the flat plates, which are parallel to the flat The direction of the plate becomes a slow phase axis, and the direction perpendicular to the plate becomes the phase axis. Thereby, two regions having different optical axes can be alternately formed on one piece of the substrate. Further, according to the material and design value of the fine periodic structure, the phase difference of each region is set to 1/4 wavelength of the light wavelength, and the optical axes of the respective regions are orthogonal. Further, the two regions are set as the right-eye polarizing portion and the left-eye polarizing portion, and the right-eye polarizing portion overlaps the right-eye image of the liquid crystal display panel, and the left-eye polarizing portion and the liquid crystal display panel are The image for the left eye is superimposed, and the optical axis of the two regions is formed at an angle of ±45 degrees with respect to the polarization axis of the polarizing plate on the liquid crystal display panel, so that the phase difference plate is bonded to the liquid crystal display panel. . Therefore, when the linear polarized light emitted from the polarizing plate on the liquid crystal display panel passes through the phase difference plate, it changes to the right circular polarized light and the left circular polarized light, and when the image displayed on the liquid crystal display panel is observed through the polarized glasses, the The light of the pixel for the right eye does not reach the left eye but only reaches the right eye, and the light from the pixel for the left eye does not reach the right eye but only reaches the left eye, whereby the liquid crystal display panel can display the parallax image. Perform stereo display.

Line, the left-eye polarizing portion of the phase difference plate is superimposed on the scanning of the liquid crystal display panel The left eye of the trace is formed by means of a pixel line.

Hereinafter, the operation of this embodiment will be described. First, as shown in FIG. 6, the conveyance unit 8 conveys the liquid crystal display panel 1 below the exposure apparatus 30a. At this time, the hard sheet alignment camera 25 detects the alignment marks 9 provided on the four corners of the liquid crystal display panel 1 to detect the position of the liquid crystal display panel 1. Based on this detection result, the position of the liquid crystal display panel 1 is appropriately adjusted. Then, the exposure device 30a traces the pixel line so that the opening portion 7a is correctly positioned above the right-eye pixel 11a of the liquid crystal display panel 1, and as shown in Fig. 7, in the one direction by the transport portion 8 (the In the liquid crystal display panel 1 transported by the hollow arrow, the exposure light source 26a of the exposure device 30a exposes a portion of the alignment film corresponding to the right-eye pixel 11a to form a right-eye polarizing portion 12a.

Then, as shown in FIG. 8, after the right-eye polarizing portion 12a is formed on all of the portions corresponding to the right-eye pixel 11a on the alignment film of the liquid crystal display panel 1, the opening portion 7a of the mask 3a is positioned on the liquid crystal display panel 1. The adjustment unit moves the mask 3a of the exposure device 30a in a direction perpendicular to the one direction by a portion of the left-eye pixel 11b. Then, as shown in FIG. 9, the liquid crystal display panel 1 is conveyed in a direction opposite to the conveyance direction when the right-eye polarizing portion 12a is formed (indicated by a hollow arrow in FIG. 9), and exposure is performed from the exposure light source 26a. The light is switched to the left eye with the exposure light of the polarized light. By this, the liquid crystal display panel 1 that is being transported is exposed to the portion corresponding to the left-eye pixel 11b on the alignment film via the mask 3a to form the left-eye polarizing portion 12b. In the present embodiment, after the right-eye polarizing portion 12a is formed, the photomask 3a is moved (shifted) by only one pixel line, but the carrier can be moved by the liquid crystal display panel 1 by adsorption. (Offset), and the liquid crystal display panel 1 is only moved (offset) by the amount of one pixel line.

In the fourth embodiment, since the right-eye polarizing unit 12a and the left-eye polarizing unit 12b are formed by one exposure apparatus, the cost for the exposure apparatus can be reduced, and the entire apparatus can be downsized.

Further, in the manufacturing apparatus of the ternary liquid crystal display device of each of the above embodiments, the reticle of the exposure device has an opening portion having a size corresponding to the pixel line. First, the pair of exposure devices 30a on the alignment film Exposing the portion of the right-eye pixel 11a to form the right-eye polarizing portion 12a, and then the exposure device 30a moves the amount of one pixel line in a direction perpendicular to the conveyance direction of the liquid crystal display panel 1, and the corresponding left on the alignment film The portion of the ophthalmic pixel 11b is exposed to form a left-eye polarizing portion 12b. In other words, one exposure device sequentially exposes the alignment film corresponding to the right-eye pixel and the left-eye pixel by a photomask having an opening portion corresponding to the pixel line, thereby pressing each pixel line. Differently forming different polarizing portions.

However, the present invention is not limited to the above-described first to fourth embodiments. For example, the mask 3a of the exposure device 30a may have an opening portion 7a having a size corresponding to a pixel line of every other pixel line, and an exposure device. The mask 3b of 30b has one opening extending in the entire length direction of the pixel region. In this case, the exposure light of the exposure device 30b is moved by the liquid crystal display panel 1, and the entire alignment film 35 is exposed. With this configuration, first, the exposure device 30a exposes a portion of the alignment film corresponding to the right-eye pixel 11a to form a right-eye polarizing portion 12a, and then the exposure device 30a is used for the right-eye pixel 11a and the left eye. The alignment film corresponding to both of the pixels 11b is exposed. In this case, the energy of the exposure light of the exposure device 30b is such that the right eye of the portion corresponding to the right-eye pixel 11a formed on the alignment film is not considered in consideration of the low energy of the polarization direction of the right-eye polarizing portion 12a. The polarizing portion 12a is maintained as it is, and the left-eye polarizing portion 12b is formed only in the region of the alignment film 35 corresponding to the left-eye pixel 11b.

Further, for example, the mask 3a of the exposure device 30a may have an opening corresponding to the entire area in the width direction of the pixel region. The exposure device 30a irradiates the entire alignment film 35 with exposure light by the movement of the liquid crystal display panel 1. The mask 3b of the exposure device 30b has an opening portion 7b of a size corresponding to the pixel line of every other pixel line, and the exposure device The exposure light of 30b exposes an area of the alignment film corresponding to the pixel line for the left eye. With this configuration, first, the exposure device 30a exposes the entire alignment film 35, and then the exposure device 30a exposes only the portion of the alignment film corresponding to the left-eye pixel 11b. In this case, the energy of the exposure light of the exposure device 30b can be sufficiently used to change the alignment film portion of the right-eye polarizing portion that has been exposed by the exposure device 30a to the polarization direction for the left eye. The alignment film region corresponding to the pixel line for the left eye is made into the left-eye polarizing portion by the exposure device 30b. Thereby, the left-eye polarizing portion 12b is formed on the portion corresponding to the left-eye pixel 11b on the alignment film, and the alignment film portion corresponding to the right-eye pixel 11a which is not exposed by the exposure light of the exposure device 30b remains. There is a polarizing portion 12a for the right eye. Further, in the present invention, the right-eye polarizing portion and the left-eye polarizing portion formed in the liquid crystal display panel may be circularly polarized portions or may be linearly polarized portions.
