BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device and a method of manufacturing a liquid crystal display device, and more particularly to a bonding device for bonding a 3D display panel using an annularly disposed bonding agent ( A liquid crystal display device of a 3D display panel and a substrate of a liquid crystal display panel, and a method of manufacturing the liquid crystal display device. [Prior Art] A display that is common on the market generally cannot produce a three-dimensional feeling in the user's brain through the eyes of the user. However, with the advancement of optical technology, more and more display manufacturers have invested in the research and manufacture of 3D stereoscopic displays. At present, 3D image display technology can be divided into two major categories, namely, "wearing glasses" and "naked eye". The main difference is that the technology of wearing glasses still requires the user to wear a specific pair of glasses. Realistic 3D images are formed in the user's eyes, while the "naked-eye" technology eliminates the need for users to wear specific glasses to create realistic 3D images in the eye. "With glasses" 3D image display technology As a 3D imaging panel, the phase difference plate is a low-cost and feasible technology. It mainly attaches a phase difference plate to a polarizing plate of a general display, wherein the phase difference plate uses molecules arranged in a certain direction to make incidence. The polarized light of the phase difference plate produces rotation in different directions due to different phase differences. When the phase difference plate is attached to the polarizing plate of the display, the light source passes through the phase difference plate before the LCD screen is imaged, and the visual field of the left and right eyes of the user is separately processed according to the difference of the phase difference, so that the user can Eyes 201107790 . Forms realistic 3D images.

In addition, in the "naked-eye" 3D image display technology, common 3D imaging panels include Lenticular Lens and Parallel Barrier. The lenticular sheet is attached to a substrate with a microlens structure; the lenticular sheet is attached to the upper polarizing plate of the general display, and the 3D left-eye image signal displayed by the general display is focused on the user. The left eye, while the 3D right eye image signal displayed on the general display is focused to the same • The user's right eye 'users observe realistic 3D images by receiving different image signals of the left and right eyes.

The parallax barrier plate is attached to a substrate with a diaphragm having a light barrier structure; the parallax barrier plate is attached to the upper polarizing plate of the general display, so that the left eye of the user can only see the display of the general display. The 3D left-eye image signal 'the user's right eye can only see the 3D right-eye image signal displayed by the general display'. The user observes the realistic 3D image by receiving different image signals of the left and right eyes. # 裸眼的技术 is the ultimate goal of 3D display pursuit, but limited by the current technical limitations and cost considerations, in a short period of time, the "glass-wearing" technology will still be the development of 3D image display technology. Mainstream. At present, the technique of attaching a 3D imaging panel to a polarizing plate of a display mainly applies the bonding adhesive to the bottom surface of the 3D developing panel. The receiver 'aligns the 3D display panel with the liquid crystal display unit (LiqUid Crystal Display Cell; LCD Cell), wherein the uppermost layer of the LCD unit is provided with a substrate (generally glass) on which a polarizing plate and an LCD are disposed. The unit is joined to the 3D image panel by the polarizing plate through the adhesive material. Alignment step 201107790

'There must still be UV-known to illuminate, after the heating and pressing step, it must still be known as uv.

In addition, the technique of attaching a 3D imaging panel to a polarizing plate of a display is to coat the bottom surface of the developing panel with a double gamma in a double gamma, or to coat the LCD unit in a double Y shape. The surface of the substrate. Next, the alignment step of the 3D development panel and the LCD unit is performed. After the alignment step is completed, the 3D development panel and the LCD unit are placed in a vacuum environment, and then the 3D, ', and the member φ plate are placed on the substrate of the LCD unit and then pressurized so that: double Y The coated adhesive is spread to a space between the 3D developing panel and the substrate of the lcd unit, and finally heated to complete the bonding of the 3D to the LCD unit.

In the present embodiment, the geometry of the bonding agent 108 is as shown in FIG. 1A and the structure shown in FIG. 1B is known. Since the area of the substrate 512 is larger than the area of the phase difference plate 106, the phase difference plate 106 is disposed. On the substrate 512 10 201107790, the bonding agent 108 is positioned between the surface 512a of the substrate 512 and the side of the phase difference plate 106, thereby bonding the substrate 512 and the phase difference plate 106.

In other special cases, the geometry of the phase difference plate 1G6 is not 1A and the rectangular shape are limited, and the phase difference plate 1〇6 may have other rectangles such as a circle, a polygon or a four-terminal rounded corner. In the embodiment, the material of the bonding agent (10) is (4) a cured profile= For example, in general, a uv-curable material is used. Therefore, in the process of the liquid crystal display device, the light-curing material of the bonding agent (10) must be irradiated with a radiation source (such as a uv light source) so that the bonding agent is just solidified, thereby The substrate 512 / the upper polarizing plate 514 and the phase difference plate 1 6 are joined by three elements. In other specific embodiments, the material of the bonding agent (10) may be a thermosetting material, and the manufacturing of the liquid crystal display device The process towel must heat the bonding agent 108 with a heat source.

The range surrounded by the vertical projection is smaller than the range surrounded by the vertical projection of the periphery of the phase difference plate 206. When the upper polarizing plate 214 is disposed under the phase difference plate 206, the upper polarizing plate 214 is completely in place. The periphery of the phase difference plate 206 Within the range surrounded by the shadow, a space 21 所示 as shown in Fig. 2 is formed. In the liquid crystal display device 500 shown in Figs. 1A and 1B, the area of the upper polarizing plate 514 and the phase difference plate 106 are the same. Therefore, the upper polarizing plate 514 is aligned with the periphery of the phase difference plate 106 in addition to the range surrounded by the vertical projection of the periphery of the phase difference plate 106. Therefore, the space 210 described above cannot be formed. 3 is a cross-sectional view showing the phase difference plate 306 and the substrate 312 of the liquid crystal display unit according to another embodiment of the present invention. In the structure shown in FIG. 3, the phase difference plate 306 and the substrate are shown. The relative relationship between the 312 is similar to the relationship between the phase difference plate 106 and the substrate 512 in the structure shown in FIG. 1B, and therefore the structure and variations are not described again. Only the differences will be described below. The upper polarizing plate 314 is interposed between the substrate 312 and the phase difference plate 306, and the bonding agent 308 is in contact with one surface of the substrate 312 and the side surface of the phase difference plate 306, and is continuously looped on the side of the phase difference plate 306. on. In the present embodiment, the area of the upper polarizing plate 314 is larger than the area of the phase difference plate 306, that is, the range surrounded by the vertical projection of the periphery of the upper polarizing plate 314 is larger than the vertical projection of the periphery of the phase difference plate 306. The range that surrounds it. When the upper polarizing plate 314 is disposed under the phase difference plate 306, the phase difference plate 306 is completely within the range surrounded by the vertical projection of the periphery of the upper polarizing plate 314. In addition, the area of the substrate 312 is also larger than the area of the upper projection 201107790 light plate 314, that is, the range surrounded by the vertical projection of the periphery of the substrate 312, which is larger than the range surrounded by the vertical projection of the periphery of the upper polarizing plate 314. When the substrate 312 is disposed under the upper polarizing plate 314, the upper polarizing plate 314 is completely within the range surrounded by the vertical projection of the periphery of the substrate 312. In the present embodiment, the vertical section of the substrate 312 has a vertical side 312a, the vertical section of the upper polarizer 314 has a vertical side 314a, and the vertical section of the phase difference plate 306 has a vertical side 306a. The vertical sections of the substrate 312, the upper polarizing plate 314 and the phase difference plate 306 are coplanar, that is, the vertical sections of the above three form a part of the vertical section of the entire liquid crystal display device, and the vertical side 312a and the vertical side thereof The 314a and the vertical side 306a are positioned on the same side of the liquid crystal display device. The vertical side 306a and the vertical side 314a have a minimum distance d1, and the vertical side 306a and the vertical side 312a have a minimum distance d2, wherein the ratio of the minimum distance dl to the minimum distance d2 is less than or equal to 5%. Further, in the present embodiment, the minimum distance d2 is greater than or equal to 0.6 mm. In this embodiment, the plurality of minimum distances d1 and the plurality of minimum distances d2 generated by any vertical section (coplanar) of the substrate 312, the upper polarizing plate 314, and the phase difference plate 306 have the minimum distance d1. The ratio of the minimum distance d2 is less than or equal to 5%, and each minimum distance d2 is greater than or equal to 0.6 mm. Please also refer to ΙΑ, 1B and 3 at the same time. The upper polarizing plate 514 shown in FIGS. 1A and 1B is completely retracted into the range surrounded by the vertical projection of the periphery of the phase difference plate 106, so that the bonding agent 108 is mainly connected to the side of the phase difference plate 106 and the substrate 512. The surface 512a is in contact, whereby the substrate 201107790 512, the upper polarizing plate 514, and the phase difference plate i〇6 are joined. The phase difference plate 106 includes a transparent substrate 106a and a phase difference film i〇6b, and in general design, the thickness of the transparent substrate 106a is larger than the thickness of the phase difference film 1〇6b, and the transparent substrate 106a— The material is glass, so the bonding agent 1〇8 is mainly made of two similar glass materials.

As shown in FIG. 3, the upper polarizing plate 314 protrudes beyond the range surrounded by the vertical projection of the periphery of the phase difference plate 306, so that the bonding agent 308 is apart from the side of the phase difference plate 306 and the substrate 312. In addition to the surface contact, a part of the upper polarizing plate 314 which is beyond the periphery of the protruding phase difference plate 3〇6 is in contact with the side surface. In the selection of the general material, the material of the upper polarizing plate 314 is different from the material contained in the substrate 312 and the phase difference plate 3〇6, wherein the material of the substrate 312 and the main material of the phase difference plate 3〇6 (in the phase difference plate) The material of the transparent substrate is generally a similar glass material. Therefore, the bonding agent 308 is used to join two similar glass materials, and it is sufficient to simultaneously join the non-glass material selected for the polarizing plate 314.

According to the above, in order to be able to join two different materials at the same time, the selection conditions of the mixture 1〇8, the selection conditions of the bonding agent should be two, and strict, even if the supplier of the relevant bonding agent is required to be specially developed, Easy to increase the cost of the product. However, the Nylon cement does not effectively bond the two different materials to the two different materials, which tends to cause the difference between the layers of the front plate, the upper polarizer 3M and the substrate 312, which increases the defective rate of the product. ^ Ϊ 3 In the structure shown in the figure, 'If you consider the cost of the bonding agent 308, you must control the ratio of the minimum distances dl W and ^d2 to ensure the area of the right enough coating. The bonding agent m 15 201107790 . 308′ further reduces the probability of peeling between the layers of the phase difference plate 306, the upper polarizing plate 314 and the substrate 312, so that the ratio of the minimum distance d1 to the minimum distance d2 is less than or equal to 5% and the minimum distance. The purpose of d2 being greater than or equal to 0.6 mm is here. Referring to Figure 4, there is shown a cross-sectional view of a phase difference plate 406 bonded to a substrate 412 of a liquid crystal display unit in accordance with another embodiment of the present invention. In the structure shown in Fig. 4, the relative relationship between the phase difference plate 406 and the substrate 412 is similar to the relationship between the phase difference plate 306 and the base φ plate 312 shown in Fig. 3, so The structure and changes will not be described again. The following only explains the differences. The upper polarizing plate 414 is interposed between the substrate 412 and the phase difference plate 406, and the bonding agent 408 is in contact with one surface of the substrate 412 and the side surface of the phase difference plate 406, and is continuously looped on the side of the phase difference plate 406. on. In the present embodiment, the phase difference plate 406 is in contact with the upper polarizing plate 414 with the bottom surface. In order to increase the bonding area of the bonding agent 408, the bonding agent 408 is applied between the top surface of the glass substrate 412 and the side surface of the phase difference plate 406. The outer portion of the bonding agent 408 is coated by the phase difference plate 406. The sides extend to the top surface. Referring to Figure 6, there is shown a cross-sectional view of a phase difference plate 706 joined to a substrate 712 of a liquid crystal display unit in accordance with another embodiment of the present invention. In the structure shown in the second figure, the relative relationship between the phase difference plates 7〇6 and the substrate 712 is similar to the relationship between the phase difference plate 206 and the substrate 212 shown in FIG. 2, so The structure and changes are not described again. 'The following is only the difference. The upper polarizer 714 is interposed between the substrate 712 and the phase difference plate 706, and the bonding agent 708 has a portion extending to the phase difference except for one surface of the substrate 712 201107790 and the side surface of the phase difference plate 706. The bottom surface of the plate 706, that is, is sandwiched between the top surface of the substrate 712 and the bottom surface adjacent to the side surface of the phase difference plate 706. In other words, the bonding agent 708' interposed between the top surface of the substrate 712 and the bottom surface of the phase difference plate 706 is in contact with a peripheral region of the bottom surface of the phase difference plate 706. In addition, in order to avoid the problem that the bonding agent 708 infiltrates between the phase difference plate 706 and the upper polarizing plate 714 or infiltrates between the upper polarizing plate 714 and the substrate 712, the problem of overflowing is generated. After 712 φ is bonded to the phase difference plate 706, a space 710 is formed between the bonding agent 708 and the upper polarizing plate 714. Referring to Fig. 7, a cross-sectional view of a phase difference plate 806 and a substrate 812 of a liquid crystal display unit according to another embodiment of the present invention is shown. In the structure shown in Fig. 7, the relative relationship between the phase difference plates 8〇6 and the substrate 812 is similar to the relationship between the phase difference plate 206 and the substrate 212 shown in Fig. 2, so The structure and changes will not be described again. The following only explains the differences. The upper polarizing plate 814 is interposed between the base φ plate 812 and the phase difference plate 806. The bonding agent 808 is in contact with the substrate 812 and the surrounding area of the bottom surface of the phase difference plate 806, wherein the surrounding area is adjacent to the bottom surface of the phase difference plate 806. An annular area. In this embodiment, the bonding agent 808 differs from the bonding agent 8〇8 shown in the above FIGS. 1A to 6 in that the bonding agent 808 is not in contact with the side surface of the phase difference plate 8〇6, but only with the phase difference plate. The surrounding area of the bottom surface of the 806 is in contact. There is a slight space between the bonding agent 8〇8 and the periphery (edge) of the phase plate 806, and in a specific embodiment, the bonding agent 8〇8 may extend to the periphery of the bottom surface of the phase difference plate 8〇6. 201107790 In addition, since the bonding agent 808 shown in FIG. 7 is only in contact with the substrate 812 and the surrounding area of the bottom surface of the phase difference plate 806, the bonding agent 8〇8 is first applied to the surrounding area of the bottom surface of the phase difference plate 806, or After the annular region 'coated on the substrate 812' and after the bonding substrate 812 and the phase difference plate 806, the annular region on the substrate 812 and the surrounding region of the bottom surface of the phase difference plate 806 correspond to each other, so that the bonding agent 808 can The peripheral regions of the bottom surface of the phase difference plate 806 are in contact with each other. In addition, in order to prevent the substrate 812 from being bonded to the phase difference plate 806, the φ bonding agent 808 penetrates between the phase difference plate 806 and the upper polarizing plate 814, or penetrates between the upper polarizing plate 814 and the substrate 812 to cause a problem of overflowing glue. It is necessary to consider at the time of product design that after the substrate 812 is bonded to the phase difference plate 806, a space 810 is formed between the bonding agent 808 and the upper polarizing plate 814.
