[0046] DP: Display Panel DETAILED DESCRIPTION

[0047] The present invention is susceptible to various modifications and may have a variety of embodiments, specific embodiments of which are illustrated in the drawings and described in detail in the detailed description. Figure 1 The effects and features of the present invention and methods of achieving them will become clear from the detailed description of the embodiments. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various ways.

[0048] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing with reference to the accompanying drawings, the same or corresponding components are given the same reference numerals and their repeated description will be omitted.

[0049] In the following embodiments, the terms "first" and "second" are not intended to be limiting but are used to distinguish one constituent element from another constituent element.

[0050] In the following embodiments, an expression in the singular includes an expression in the plural unless clearly defined differently in the context.

[0051] In the following embodiments, terms such as including or having refer to the presence of features or constituent elements described in the specification, and do not preclude the possibility of the addition of one or more other features or constituent elements.

[0052] In the following embodiments, when it is described that a part of a film, a region, a constituent element, etc. is on or above another part, it includes not only the case where it is directly on the other part, but also the case where other films, regions, constituent elements, etc. are interposed therebetween.

[0053] In the drawings, the dimensions of the components may be exaggerated or reduced for the convenience of explanation. For example, the dimensions and thickness of each component shown in the drawings are arbitrarily shown for the convenience of explanation, and therefore the present invention is not necessarily limited to the illustrated case.

[0054] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to the three axes in the orthogonal coordinate system, and can be interpreted as including the broad meaning thereof. For example, the x-axis, y-axis, and z-axis can be orthogonal to each other, but can also indicate different directions that are not orthogonal to each other.

[0055] When any embodiment can be implemented differently, a specific process sequence may be performed differently from the described sequence. For example, two processes described successively may be performed substantially simultaneously, or in a sequence opposite to the described sequence.

[0056] Figure 1 is a schematic perspective view of a manufacturing device 1 for a display device according to an embodiment of the present invention, Figure 2 is a schematic three-dimensional diagram of a display panel DP according to an embodiment of the present invention.

[0057] Reference Figure 1 and Figure 2 The manufacturing apparatus 1 of the display device may include a workbench 11, a close contact portion 12, a moving portion 13, a sensor portion 14 and a control portion (not shown).

[0058] The display panel DP may include a display substrate DS and an adhesive part AD.

[0059] The display substrate DS may be configured to be in a rectangular shape on a plane. Figure 2 As shown, the display substrate DS may have a rectangular planar shape, the rectangle having a long side in a first direction (e.g., x direction) and a short side in a second direction (e.g., y direction). The first direction (e.g., x direction) and the second direction (e.g., y direction) may intersect each other. The corner where the long side in the first direction (e.g., x direction) intersects with the short side in the second direction (e.g., y direction) may be formed into a circle to have a predetermined curvature or formed into a right angle. The planar shape of the display substrate DS is not limited to a rectangle, and may be formed into other polygonal, elliptical or irregular shapes. At this time, the display substrate DS may have a plurality of ends spaced apart from each other on a plane. For example, the display substrate DS may include a first end ED1 and a second end ED2.

[0060] The adhesive component AD may be attached to the display substrate DS. The adhesive component AD may be arranged on the display substrate DS and fixed to the display substrate DS. The adhesive component AD may be provided in plurality. Multiple adhesive components AD may be arranged on the display substrate DS in a state of being separated from each other. That is, the multiple adhesive components AD may not be provided as a whole. The multiple adhesive components AD may be fixed to the display substrate DS in a manner of contacting each other or being spaced apart from each other. For example, the thicknesses of the multiple adhesive components AD may be the same as each other. However, this is only an exemplary case, and the thicknesses of at least two of the multiple adhesive components AD may be different from each other.

[0061] For example, the adhesive part AD may include a first adhesive part AD1, a second adhesive part AD2, and a third adhesive part AD3. For example, on the display substrate DS, the first adhesive part AD1 and the third adhesive part AD3 may contact each other, and the first adhesive part AD1 and the second adhesive part AD2 may be spaced apart from each other. For example, the shapes of the first adhesive part AD1, the second adhesive part AD2, and the third adhesive part AD3 may be different from each other. However, this is only an example, and the number, arrangement, and shape of the plurality of adhesive parts AD are not limited thereto.

[0062] The workbench 11 may fix the display panel DP. The workbench 11 may support one side of the display panel DP. The display panel DP arranged on the workbench 11 may not move relative to the workbench 11. For example, the workbench 11 may be configured as an electrostatic chuck using electrostatic force or a porous chuck using vacuum adsorption force.

[0063] The adhesive part 12 can be closely attached to the adhesive component AD and the display substrate DS. The adhesive part 12 can be arranged on the workbench 11. In this structure, the display panel DP can be arranged between the workbench 11 and the adhesive part 12. Figures 3 to 5 A specific description of the close contact portion 12 will be described.

[0064] The moving part 13 can move the close contact part 12 in a first direction (e.g., x direction) and a second direction (e.g., y direction) relative to the workbench 11. In addition, the moving part 13 can rotate the close contact part 12 around a third direction (e.g., z direction). Here, the third direction (e.g., z direction) can be a direction that intersects the first direction (e.g., x direction) and the second direction (e.g., y direction). In addition, the third direction (e.g., z direction) can be a direction from the adhesive component AD to the display substrate DS or a direction from the display substrate D to the adhesive component AD.

[0065] For example, the moving part 13 may include a first moving part 131, a second moving part 132 and a third moving part 133. The first moving part 131 may be connected to the workbench 11. The first moving part 131 may move linearly in a first direction (e.g., x direction) relative to the workbench 11. For example, the first moving part 131 may include a linear motor. The second moving part 132 may be connected to the first moving part 131. The second moving part 132 may move linearly in a second direction (e.g., y direction) relative to the first moving part 131. For example, the second moving part 132 may include a linear motor. The third moving part 133 may be connected to the second moving part 132. The third moving part 133 may rotate with respect to the second moving part 132 with a third direction (e.g., z direction) as the center. For example, the third moving part 133 may include a rotary motor. The contact part 12 may be fixed to the third moving part 133. In this structure, the contact portion 12 can move relative to the stage 11 in a first direction (eg, x direction) and a second direction (eg, y direction), and can rotate around a third direction (eg, z direction).

[0066] However, this is only an exemplary case, and the structure, number and connection relationship of the moving part 13 are not limited thereto. For example, the moving part 13 may be provided by only a plurality of linear motors, or may be provided by only a plurality of rotary motors. Alternatively, the moving part 13 may also adjust the positional relationship between the close contact part 12 and the workbench 11 in a UVW workbench structure manner.

[0067] The sensor unit 14 can sense the position information of the display panel DP. For example, the sensor unit 14 can sense the positions of the two ends of the display panel DP. For example, the sensor unit 14 can sense the positions of the first end ED1 and the second end ED2 of the display panel DP. However, this is only an exemplary case, and the method of sensing the position information of the display panel DP is not limited thereto. For example, more than one alignment mark can be marked on the display panel DP, and the sensor unit 14 can sense the alignment mark.

[0068] exist Figure 1 In the figure, two sensor parts 14 are respectively fixed to the close contact part 12, but the number and arrangement of the sensor parts 14 are not limited thereto. For example, one sensor part 14 fixed to the workbench 11 can sense the position information of the display panel DP.

[0069] The control unit (not shown) can control the close contact unit 12 and the moving unit 13. Figures 6 to 17 Specific instructions for a controller (not shown) are described.

[0070] Figures 3 to 5 1 is a schematic cross-sectional view of the close contact portion 12 according to an embodiment of the present invention. Specifically, Figure 3 Can correspond to Figure 1 The III-III' line, Figure 4 Can correspond to Figure 1 The IV-IV' line, Figure 5 Can correspond to Figure 1 The V-V' line.

[0071] For ease of explanation, Figure 4 The first pressurizing portion 122 and the first position adjusting portion 123 are omitted in the figure.

[0072] Reference Figure 1 and Figures 3 to 5 The contact portion 12 may include a pressurizing frame 121 , a first pressurizing portion 122 , a first position adjusting portion 123 , a second pressurizing portion 124 , and a second position adjusting portion 125 .

[0073] The pressurizing frame 121 may form the appearance of the close-fitting portion 12. The pressurizing frame 121 may be fixed to the moving portion 13. Therefore, the pressurizing frame 121 may perform relative movement with respect to the workbench 11. The pressurizing frame 121 may provide an internal space. In the internal space of the pressurizing frame 121, at least a portion of the first pressurizing portion 122, the first position adjusting portion 123, the second pressurizing portion 124, and the second position adjusting portion 125 may be arranged.

[0074] Reference Figure 3 and Figure 5 The first pressurizing portion 122 may include a first rail portion 1221 and a plurality of first pressurizing modules 1222 .

[0075] The first rail portion 1221 may be fixed to the pressurizing frame 121. The first rail portion 1221 may guide the movement of the plurality of first pressurizing modules 1222. The first rail portion 1221 may be arranged to extend along the second direction (eg, the y direction). Both ends of the first rail portion 1221 may be fixed to the pressurizing frame 121.

[0076] The plurality of first pressurizing modules 1222 may be movable along the first rail portion 1221. The plurality of first pressurizing modules 1222 may be slidably connected to the first rail portion 1221 and linearly move along the second direction (e.g., the y direction). The plurality of first pressurizing modules 1222 may pressurize the adhesive component AD in a third direction (e.g., the -z direction). The plurality of first pressurizing modules 1222 may move in the second direction (e.g., the y direction) along the first rail portion 1221 and then pressurize the display panel DP arranged on the workbench 11 in the third direction (e.g., the -z direction) at a designated position.

[0077] exist Figure 3 It is shown that there are three first pressurizing modules 1222 , but this is just an example, and the number of the first pressurizing modules 1222 is not limited thereto.

[0078] Each of the plurality of first pressurizing modules 1222 may include a first connecting portion 12221 , a first pressurizing contact portion 12222 , a first roller portion 12223 , and a first roller moving portion 12224 .

[0079] The first connection portion 12221 may be connected to the first rail portion 1221. The first connection portion 12221 may be able to slide and move in the second direction (e.g., the y direction). The first connection portion 12221 may be able to switch between the 1-1 condition in which it is able to move freely along the first rail portion 1221 and the 1-2 condition in which it is fixed to the first rail portion 1221. For example, the first connection portion 12221 may be provided with a hydraulic brake. Therefore, under the 1-1 condition, the first connection portion 12221 moves freely along the first rail portion 1221, and then under the 1-2 condition, the first connection portion 12221 may be fixed to the first rail portion 1221 while the hydraulic brake is operating.

[0080] The first press contact portion 12222 may be fixed to the first connection portion 12221. The first press contact portion 12222 may be able to contact the first position regulating portion 123. The first press contact portion 12222 may be arranged at the first connection portion 12221 in such a manner as to face the first position regulating portion 123.

[0081] The first roller portion 12223 may be rotatable around the rotation axis. For example, the first roller portion 12223 may be freely rotatable around the first direction (e.g., the x direction). The first roller portion 12223 may extend in the first direction (e.g., the x direction). Therefore, the first roller portion 12223 and the adhesive component AD may be in line contact, and the contact line between the first roller portion 12223 and the adhesive component AD may also have the first direction (e.g., the x direction).

[0082] The first roller moving portion 12224 can connect the first roller portion 12223 and the first connecting portion 12221, and move the first roller portion 12223 in a third direction (e.g., z direction). One side of the first roller portion 12223 can be fixed to the first connecting portion 12221, and the other side of the first roller portion 12223 can be fixed to the first roller portion 12223. In this case, the first roller portion 12223 can be arranged toward the display panel DP relative to the first connecting portion 12221. For example, the first roller portion 12223 may include a linear motor. In this structure, the first roller portion 12223 can move linearly along the third direction (e.g., z direction) relative to the first connecting portion 12221.

[0083] The first position adjusting part 123 may adjust the position of at least one of the plurality of first pressurizing modules 1222. The first position adjusting part 123 may include a first position adjusting module 1231 and a first position adjusting moving part 1232.

[0085] The first position adjustment contact portion 12311 may be capable of contacting the first pressure contact portion 12222. The first contact moving portion 12312 may enable the first position adjustment contact portion 12311 to move in a third direction (e.g., z direction). The first position adjustment contact portion 12311 may be connected to the first contact moving portion 12312 in a manner facing the first pressurizing portion 122. For example, the first contact moving portion 12312 may include a linear motor.

[0086] The first position adjustment moving part 1232 can be fixed to the pressurizing frame 121 and connected to the first contact moving part 12312 to move the first contact moving part 12312. The first position adjustment moving part 1232 can make the first contact moving part 12312 move linearly along the second direction (e.g., the y direction). The first position adjustment contact part 12311 can be arranged relative to the first contact moving part 12312 toward the first pressure contact part 12222.

[0087] The first position-adjusting moving portion 1232 may include a first supporting portion 12321 and a first driving portion 12322 .

[0088] The first support portion 12321 may support the first position adjustment module 1231. The first support portion 12321 may extend in the second direction (e.g., the y direction), and the first support portion 12321 and the first position adjustment module 1231 may be fixed to each other. The first support portion 12321 may linearly move in the second direction (e.g., the y direction) relative to the pressurizing frame 121.

[0089] The first driving part 12322 can move the first supporting part 12321. The first driving part 12322 can be fixed to the pressurizing frame 121 and connected to the first supporting part 12321. The first driving part 12322 can make the first supporting part 12321 move linearly along the second direction (e.g., the y direction). As the first driving part 12322 moves the first supporting part 12321, the first position adjustment module 1231 fixed to the first supporting part 12321 can also move together.

[0090] Reference Figure 4 and Figure 5 The second pressurizing portion 124 may include a second rail portion 1241 and a plurality of second pressurizing modules 1242 .

[0091] The second rail portion 1241 may be fixed to the pressurizing frame 121. The second rail portion 1241 may guide the movement of the plurality of second pressurizing modules 1242. The second rail portion 1241 may be arranged to extend along a second direction (eg, y direction). Both ends of the second rail portion 1241 may be fixed to the pressurizing frame 121.

[0092] The plurality of second pressurizing modules 1242 may be movable along the second rail portion 1241. The plurality of second pressurizing modules 1242 may be slidably connected to the second rail portion 1241 and linearly move along the second direction (e.g., the y direction). The plurality of second pressurizing modules 1242 may pressurize the adhesive component AD in a third direction (e.g., the -z direction). The plurality of second pressurizing modules 1242 move in the second direction (e.g., the y direction) along the second rail 1241 and then pressurize the display panel DP arranged on the workbench 11 in the third direction (e.g., the z direction) at a designated position.

[0093] exist Figure 4 It is shown that there are two second pressurizing modules 1242 , but this is just an example, and the number of the second pressurizing modules 1242 is not limited thereto.

[0094] Each of the plurality of second pressurizing modules 1242 may include a second connecting portion 12421 , a second pressurizing contact portion 12422 , a second roller portion 12423 , and a second roller moving portion 12424 .

[0095] The second connection portion 12421 may be connected to the second rail portion 1241. The second connection portion 12421 may be able to slide and move in the second direction (e.g., the y direction). The second connection portion 12421 may be able to switch between the 2-1 condition in which it is able to move freely along the second rail portion 1241 and the 2-2 condition in which it is fixed to the second rail portion 1241. For example, the second connection portion 12421 may be provided with a hydraulic brake. Therefore, under the 2-1 condition, the second connection portion 12421 moves freely along the second rail portion 1241, and then under the 2-2 condition, the second connection portion 12421 may be fixed to the second rail portion 1241 while the hydraulic brake is operating.

[0096] The second press contact portion 12422 may be fixed to the second connection portion 12421. The second press contact portion 12422 may be able to contact the second position regulating portion 125. The second press contact portion 12422 may be arranged at the second connection portion 12421 in such a manner as to face the second position regulating portion 125.

[0097] The second roller portion 12423 may be rotatable around the rotation axis. For example, the second roller portion 12423 may be freely rotatable around the second direction (e.g., the y direction). The second roller portion 12423 may extend in the second direction (e.g., the y direction). Therefore, the second roller portion 12423 and the adhesive component AD may be in line contact, and the contact line between the second roller portion 12423 and the adhesive component AD may also have the second direction (e.g., the y direction).

[0098] The second roller moving portion 12424 can connect the second roller portion 12423 and the second connecting portion 12421, and move the second roller portion 12423 in a third direction (e.g., z direction). One side of the second roller portion 12423 can be fixed to the second connecting portion 12421, and the other side of the second roller portion 12423 can be fixed to the second roller portion 12423. In this case, the second roller portion 12423 can be arranged toward the display panel DP relative to the second connecting portion 12421. For example, the second roller portion 12423 may include a linear motor. In this structure, the second roller portion 12423 can move linearly along the third direction (e.g., z direction) relative to the second connecting portion 12421.

[0099] The second position adjusting part 125 may adjust the position of at least one of the plurality of second pressurizing modules 1242. The second position adjusting part 125 may include a second position adjusting module 1251 and a second position adjusting moving part 1252.

[0100] The second position adjustment module 1251 may include a second position adjustment contact portion 12511 and a second contact movement portion 12512 .

[0101] The second position adjustment contact portion 12511 may be capable of contacting the second pressurizing contact portion 12422. The second contact moving portion 12512 may enable the second position adjustment contact portion 12511 to move in a third direction (e.g., z direction). The second position adjustment contact portion 12511 may be connected to the second contact moving portion 12512 in a manner facing the second pressurizing portion 124. For example, the second contact moving portion 12512 may include a linear motor.

[0102] The second position adjustment moving part 1252 can be fixed to the pressurizing frame 121 and connected to the second contact moving part 12512 to move the second contact moving part 12512. The second position adjustment moving part 1252 can make the second contact moving part 12512 move linearly along the second direction (e.g., y direction). The second position adjustment contact part 12511 can be arranged relative to the second contact moving part 12512 toward the second pressurizing contact part 12422.

[0103] The second position-adjusting moving portion 1252 may include a second supporting portion 12521 and a second driving portion 12522 .

[0104] The second support portion 12521 may support the second position adjustment module 1251. The second support portion 12521 may extend in a second direction (e.g., y direction), and the second support portion 12521 and the second position adjustment module 1251 may be fixed to each other. The second support portion 12521 may linearly move in a second direction (e.g., y direction) relative to the pressurizing frame 121.

[0105] The second driving part 12522 can move the second supporting part 12521. The second driving part 12522 can be fixed to the pressurizing frame 121 and connected to the second supporting part 12521. The second driving part 12522 can make the second supporting part 12521 move linearly along the second direction (for example, the y direction). As the second driving part 12522 moves the second supporting part 12521, the second position adjustment module 1251 fixed to the second supporting part 12521 can also move together.

[0106] Figures 6 to 17 is a schematic cross-sectional view of a manufacturing apparatus 1 of a display device according to an embodiment of the present invention.

[0107] Specifically, Figures 6 to 12 Can correspond to Figure 1 The III-III' line, Figures 13 to 16a Can correspond to Figure 1 The IV-IV' line, Fig.16b and Fig.17 Can correspond to Figure 1 The V-V' line.

[0108] For ease of explanation, Figures 13 to 16a The first pressurizing portion 122 and the first position adjusting portion 123 are omitted in the figure.

[0109] exist Figures 6 to 17 In, with Figures 1 to 5 The same reference numerals denote the same components, and duplicate descriptions thereof will be omitted.

[0110] Reference Figures 6 to 17 , the working process of the display device manufacturing device 1 can be known. That is, the method of manufacturing the display device by the display device manufacturing device 1 can be known.

[0111] First, refer to Figure 1 and Figure 6 , the controller (not shown) can control the moving part 13 based on the position information of the display panel DP so that the contact part 12 is aligned relative to the display panel DP. For example, the moving part 13 can move the contact part 12 in a first direction (e.g., x direction) and a second direction (e.g., y direction) so that the center line CL of the contact part 12 coincides with the center line CL of the display panel DP. In addition, on a plane, the moving part 13 can rotate the contact part 12 around a third direction (e.g., z direction) to prevent the contact part 12 and the display panel DP from being misaligned with each other. Therefore, even if the display panel DP is slightly misaligned on the workbench 11, the contact part 12 can be aligned corresponding to the misalignment of the display panel DP.

[0112] Reference Figures 6 to 10If the contact portion 12 is aligned with respect to the display panel DP, the controller (not shown) may control the first position adjusting portion 123 so that the first position adjusting portion 123 adjusts the position of at least one of the plurality of first pressurizing modules 1222 .

[0113] For the sake of convenience, the description is given assuming that there are three first pressurizing modules 1222. That is, the first pressurizing modules 1222 may include a 1-1 pressurizing module 1222-1, a 1-2 pressurizing module 1222-2, and a 1-3 pressurizing module 1222-3.

[0114] Reference Figure 6 , the first position adjustment contact portion 12311 of the first position adjustment module 1231 can contact the first pressurizing contact portion 12222 of the 1-1 pressurizing module 1222-1. The first position adjustment moving portion 1232 can move the first position adjustment module 1231 to a position corresponding to the 1-1 pressurizing module 1222-1. The first contact moving portion 12312 can move the first position adjustment contact portion 12311 in a third direction (e.g., -z direction) toward the first pressurizing contact portion 12222. In this process, the first position adjustment contact portion 12311 and the first pressurizing contact portion 12222 can contact each other.

[0115] Any one of the multiple first pressurizing modules 1222 in contact with the first position adjusting module 1231 can be fixed to the first position adjusting module 1231. As the first position adjusting contact portion 12311 and the first pressurizing contact portion 12222 contact each other, the 1-1 pressurizing module 1222-1 and the first position adjusting module 1231 can be fixed to each other. Since the first connecting portion 12221 is supported by the first rail portion 1221 and the first contact moving portion 12312 is supported by the first position adjusting moving portion 1232, the distance in the third direction (for example, the z direction) between the first pressure contact portion 12222 and the first contact moving portion 12312 can be constant. Therefore, according to the shapes of the contact surfaces of the first position adjusting contact portion 12311 and the first pressurizing contact portion 12222 corresponding to each other, the 1-1 pressurizing module 1222-1 and the first position adjusting module 1231 can be fixed to each other. Figure 6 It is shown that the first pressurizing contact portion 12222 includes a wedge shape and the first position adjusting contact portion 12311 includes a convex shape, but this is only an example, and the shapes of the first pressurizing contact portion 12222 and the first position adjusting contact portion 12311 are not limited thereto.

[0116] Reference Figure 7, the first position adjustment unit 123 can adjust the position of the 1-1 pressurizing module 1222-1. At this time, the 1-1 pressurizing module 1222-1 can be the 1-1 condition that can move freely along the first track portion 1221. In the state where the 1-1 pressurizing module 1222-1 is fixed to the first position adjustment module 1231, as the first position adjustment moving unit 1232 moves the first position adjustment module 1231 in the second direction (for example, the y direction), the 1-1 pressurizing module 1222-1 can also move together in the second direction (for example, the y direction). At this time, the position of the 1-1 pressurizing module 1222-1 can be adjusted so that the center of the 1-1 pressurizing module 1222-1 corresponds to the end of the first adhesive component AD1. If the position of the 1-1 pressurizing module 1222-1 is adjusted, the 1-1 pressurizing module 1222-1 can be converted into the 1-2 condition fixed to the first track portion 1221.

[0117] Reference Figure 8 , the first position adjusting contact portion 12311 of the first position adjusting module 1231 may contact the first pressing contact portion 12222 of the 1-2 pressing module 1222 - 2 .

[0118] First, the first contact moving portion 12312 can move the first position adjustment contact portion 12311 in a direction away from the 1-1 pressurizing module 1222-1 (for example, the +z direction), so that the first position adjustment contact portion 12311 and the 1-1 pressurizing module 1222-1 are spaced apart. Thereafter, the first position adjustment moving portion 1232 can move the first position adjustment module 1231 to a position corresponding to the 1-2 pressurizing module 1222-2. The first contact moving portion 12312 can move the first position adjustment contact portion 12311 in a third direction (for example, the -z direction) toward the first pressurizing contact portion 12222. In this process, the first position adjustment contact portion 12311 and the first pressurizing contact portion 12222 can contact each other.

[0119] As the first position adjustment contact portion 12311 and the first pressurizing contact portion 12222 contact each other, the 1-2 pressurizing module 1222-2 and the first position adjustment module 1231 may be fixed to each other. The principle of fixing the 1-2 pressurizing module 1222-2 and the first position adjustment module 1231 is the same as the principle of fixing the 1-1 pressurizing module 1222-1 and the first position adjustment module 1231, and thus a detailed description thereof is omitted.

[0120] Reference Fig. 9, the first position adjustment unit 123 can adjust the position of the 1-2 pressurizing module 1222-2. At this time, the 1-2 pressurizing module 1222-2 can be the 1-1 condition that can move freely along the first track portion 1221. In the state where the 1-2 pressurizing module 1222-2 is fixed to the first position adjustment module 1231, as the first position adjustment moving unit 1232 moves the first position adjustment module 1231 in the second direction (for example, the y direction), the 1-2 pressurizing module 1222-2 can also move together in the second direction (for example, the y direction). At this time, the position of the 1-2 pressurizing module 1222-2 can be adjusted so that the center of the 1-2 pressurizing module 1222-2 corresponds to the end of the second adhesive component AD2. If the position of the 1-2 pressurizing module 1222-2 is adjusted, the 1-2 pressurizing module 1222-2 can be converted into the 1-2 condition fixed to the first track portion 1221.

[0121] Reference Fig.10 The first contact moving portion 12312 can move the first position adjusting contact portion 12311 in a direction away from the 1-2 pressurizing module 1222-2 (eg, the +z direction) so as to space the first position adjusting contact portion 12311 from the 1-2 pressurizing module 1222-2.

[0122] Reference Fig.11 If the first position adjusting unit 123 adjusts the position of at least one of the plurality of first pressurizing modules 1222, the control unit (not shown) may control the first pressurizing unit 122 so that the at least one first pressurizing module 1222 whose position is adjusted pressurizes the bonding component AD.

[0123] The first roller moving part 12224 of the 1-1st pressurizing module 1222-1 can move the first roller part 12223 in a third direction (e.g., -z direction) toward the adhesive component AD. Therefore, the first roller part 12223 of the 1-1st pressurizing module 1222-1 can pressurize the adhesive component AD in the third direction (e.g., -z direction). For example, the first roller part 12223 of the 1-1st pressurizing module 1222-1 can pressurize the end of the first adhesive component AD1.

[0124] The first roller moving part 12224 of the 1-2 pressurizing module 1222-2 may move the first roller part 12223 in a third direction (e.g., -z direction) toward the adhesive component AD. Therefore, the first roller part 12223 of the 1-2 pressurizing module 1222-2 may pressurize the adhesive component AD in the third direction (e.g., -z direction). For example, the first roller part 12223 of the 1-2 pressurizing module 1222-2 may pressurize the end of the second adhesive component AD2. The 1-1 pressurizing module 1222-1 and the 1-2 pressurizing module 1222-2 may pressurize the adhesive component AD at the same time.

[0125] Reference Figure 1 and Fig.12 If at least one first pressurizing module 1222 pressurizes the adhesive component AD, the control unit (not shown) can control the moving unit 13 to make the first pressurizing module 1222 make the adhesive component AD close to the display substrate DS. In the state where the first roller unit 12223 of the 1-1 pressurizing module 1222-1 presses the first adhesive component AD1 and the first roller unit 12223 of the 1-2 pressurizing module 1222-2 presses the second adhesive component AD2, the moving unit 13 can move the close contact unit 12 in the second direction (for example, the y direction). Therefore, the first adhesive component AD1 and the second adhesive component AD2 can be close to the display substrate DS at the same time.

[0126] Reference Figure 1 and Fig.13 , the controller (not shown) can control the moving part 13 based on the position information of the display panel DP so that the contact part 12 is aligned with respect to the display panel DP. For example, the moving part 13 can move the contact part 12 in a first direction (e.g., x direction) and a second direction (e.g., y direction) so that the center line CL of the contact part 12 coincides with the center line CL of the display panel DP. In addition, on a plane, the moving part 13 can rotate the contact part 12 around a third direction (e.g., z direction) to prevent the contact part 12 and the display panel DP from being misaligned with each other. Therefore, even if the display panel DP is arranged on the workbench 11 with a slight misalignment, the contact part 12 can be aligned corresponding to the misalignment of the display panel DP.

[0127] Reference Fig.13 and Fig.14 If the contact portion 12 is aligned with respect to the display panel DP, the control portion (not shown) may control the second position adjusting portion 125 so that the second position adjusting portion 125 adjusts the position of at least one of the plurality of second pressurizing modules 1242 .

[0128] For the sake of convenience, the description is given assuming that there are two second pressurizing modules 1242. That is, the second pressurizing modules 1242 may include a 2-1st pressurizing module 1242-1 and a 2-2nd pressurizing module 1242-2.

[0129] Reference Fig.13 , the second position adjustment contact portion 12511 of the second position adjustment module 1251 can contact the second pressurizing contact portion 12422 of the 2-1 pressurizing module 1242-1. The second position adjustment moving portion 1252 can move the second position adjustment module 1251 to a position corresponding to the 2-1 pressurizing module 1242-1. The second contact moving portion 12512 can move the second position adjustment contact portion 12511 in a third direction (e.g., -z direction) toward the second pressurizing contact portion 12422. In this process, the second position adjustment contact portion 12511 and the second pressurizing contact portion 12422 can contact each other.

[0130] Any one of the multiple second pressurizing modules 1242 in contact with the second position adjusting module 1251 can be fixed to the second position adjusting module 1251. As the second position adjusting contact portion 12511 and the second pressurizing contact portion 12422 contact each other, the 2-1 pressurizing module 1242-1 and the second position adjusting module 1251 can be fixed to each other. Since the second connecting portion 12421 is supported by the second rail portion 1241 and the second contact moving portion 12512 is supported by the second position adjusting moving portion 1252, the distance in the third direction (for example, the z direction) between the second pressure contact portion 12422 and the second contact moving portion 12512 can be constant. Therefore, according to the shapes of the contact surfaces of the second position adjusting contact portion 12511 and the second pressurizing contact portion 12422 corresponding to each other, the 2-1 pressurizing module 1242-1 and the second position adjusting module 1251 can be fixed to each other. Fig.13 It is shown that the second pressurizing contact portion 12422 includes a wedge shape and the second position adjusting contact portion 12511 includes a convex shape, however, this is only an example, and the shapes of the second pressurizing contact portion 12422 and the second position adjusting contact portion 12511 are not limited thereto.

[0131] Reference Fig.14, the second position adjustment unit 125 can adjust the position of the 2-1st pressurizing module 1242-1. At this time, the 2-1st pressurizing module 1242-1 can be the 2-1st condition that can move freely along the second track portion 1241. In a state where the 2-1st pressurizing module 1242-1 is fixed to the second position adjustment module 1251, as the second position adjustment moving unit 1252 moves the second position adjustment module 1251 in the second direction (e.g., the y direction), the 2-1st pressurizing module 1242-1 can also move together in the second direction (e.g., the y direction). At this time, the position of the 2-1st pressurizing module 1242-1 can be adjusted so that the center of the 2-1st pressurizing module 1242-1 corresponds to the end of the third adhesive component AD3. If the position of the 2-1st pressurizing module 1242-1 is adjusted, the 2-1st pressurizing module 1242-1 can be converted into the 2-2nd condition fixed to the second track portion 1241.

[0132] Reference Fig.15 The second contact moving portion 12512 can move the second position adjusting contact portion 12511 in a third direction (eg, +z direction) away from the 2-2 pressurizing module 1242-2, thereby separating the second position adjusting contact portion 12511 and the 2-2 pressurizing module 1242-2.

[0133] Reference Fig.16a and Fig.16b If the second position adjusting unit 125 adjusts the position of at least one of the plurality of second pressurizing modules 1242 , the control unit (not shown) may control the second pressurizing unit 124 to pressurize the bonding component AD with the at least one second pressurizing module 1242 whose position is adjusted.

[0134] The second roller moving part 12424 of the 2-1st pressurizing module 1242-1 can move the second roller part 12423 in the third direction (e.g., -z direction) toward the adhesive component AD. Therefore, the second roller part 12423 of the 2-1st pressurizing module 1242-1 can pressurize the adhesive component AD in the third direction (e.g., -z direction). For example, the second roller part 12423 of the 2-1st pressurizing module 1242-1 can pressurize the end of the third adhesive component AD3.

[0135] Reference Figure 1 and Fig.17 If at least one second pressurizing module 1242 pressurizes the adhesive component AD, the control unit (not shown) can control the moving unit 13 to make the second pressurizing module 1242 make the adhesive component AD come into close contact with the display substrate DS. In a state where the second roller unit 12423 pressurizes the third adhesive component AD3, the moving unit 13 can move the adhesive unit 12 in the first direction (e.g., the x direction). Therefore, the third adhesive component AD3 can come into close contact with the display substrate DS.

[0136] According to the present embodiment, since the plurality of first pressurizing modules 1222 pressurize the adhesive component AD at the same time, the manufacturing time of the display device can be shortened. In addition, due to the structure of the first position adjustment unit 123 and the second position adjustment unit 125, even if the shape of the display panel DP and the attachment position of the adhesive component AD are changed, it can be flexibly dealt with. In addition, since the plurality of first pressurizing modules 1222 are driven independently, even if the thicknesses of the plurality of adhesive components AD are different from each other, the adhesive components AD with different thicknesses can be simultaneously closely attached to the display substrate DS. In addition, since the first roller portion 12223 rotates with the first direction (e.g., the x direction) as the axis, and the second roller portion 12423 rotates with the second direction (e.g., the y direction) as the axis, the adhesive component AD can be closely attached in two directions.

[0137] Fig.18 and Fig.19 is a schematic cross-sectional view of a close contact portion 12 according to another embodiment of the present invention. Specifically, Fig.18 Can correspond to Figure 1 The III-III' line, Fig.19 Can correspond to Figure 1 The IV-IV' line.
