[0056] This invention can be modified in various ways and can have various embodiments, specific embodiments of which are illustrated in the accompanying drawings and described in detail in the accompanying description. The effects and features of this invention, as well as methods of implementing them, are described with reference to the accompanying drawings. Figure 1 The details will become clear from the embodiments described below. However, the invention is not limited to the embodiments disclosed below and can be implemented in various forms.

[0057] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing the invention with reference to the drawings, the same or corresponding components will be given the same reference numerals, and repeated descriptions thereof will be omitted.

[0058] In the following embodiments, terms such as "first" and "second" are not limiting in meaning, but are used to distinguish one constituent element from other constituent elements.

[0059] In the following embodiments, the singular expression is expressed as long as it is not explicitly indicated as different in the context, and the multiple expressions are included.

[0060] In the following embodiments, terms such as "including" or "having" indicate the presence of features or constituent elements described in the specification, without pre-excluding the possibility of adding more than one other feature or constituent element.

[0061] In the following embodiments, when a membrane, region, or constituent element is described as being on or on other parts, it includes not only cases where it is directly on other parts, but also cases where other membranes, regions, or constituent elements are located in between.

[0062] In the accompanying drawings, the dimensions of the constituent elements may be enlarged or reduced for ease of explanation. For example, since the dimensions and thicknesses of the various components shown in the drawings are arbitrarily presented for ease of explanation, the present invention is not necessarily limited to those shown in the figures.

[0063] Where a particular embodiment can be implemented differently, the specific process sequence may be performed differently than the described sequence. For example, two processes described consecutively may also be performed substantially simultaneously, or in the reverse order of the description.

[0064] In the following embodiments, when it is stated that membranes, regions, constituent elements, etc. are connected, it includes not only the case where membranes, regions, and constituent elements are directly connected, but also the case where membranes, regions, and constituent elements are indirectly connected by the intermediate intervention of other membranes, regions, and constituent elements. For example, when it is stated in this specification that membranes, regions, constituent elements, etc. are electrically connected, it includes not only the case where membranes, regions, and constituent elements are directly electrically connected, but also the case where they are indirectly electrically connected by the intermediate intervention of other membranes, regions, and constituent elements.

[0065] Figure 1 This is a front view showing a manufacturing apparatus 100 for a display device according to an embodiment of the present invention. Figure 2 This is a front view that outlines a portion of the manufacturing apparatus 100 for the display device. Figure 3 This is a top view that schematically shows the movable part 120 in the manufacturing apparatus 100 of the display device. Figure 4 It is magnification Figure 2 An enlarged view of part IV.

[0066] Reference Figures 1 to 4 The manufacturing apparatus 100 for the display device may include: an input unit 110, a moving unit 120, a grinding head 140, and a conveying unit 150.

[0067] In one embodiment, the base material M can be supplied from the outside and placed in the input section 110. In another embodiment, the input section 110 can be omitted and the base material M can be placed directly in the moving section 120. However, the following description will focus on the case where the base material M is supplied from the outside and placed in the input section 110.

[0068] The input unit 110 may include an input support unit 111, an input roller 112, and an input drive unit 113.

[0069] The insertion support 111 may include multiple frames connected to each other. At least one of the multiple frames may be fixed to the ground, the interior surface of a building, or the like to secure the insertion support 111.

[0070] The input roller 112 can be rotatably disposed on the input support portion 111. Multiple input rollers 112 can be provided, and multiple input rollers 112 can be disposed on the input support portion 111 with spaced apart from each other.

[0071] The input drive unit 113 can be connected to the input roller 112 to rotate the input roller 112. The input drive unit 113 can be connected to at least one of the plurality of input rollers 112. In one embodiment, the input drive unit 113 may include a motor, and multiple input drive units 113 may be provided and respectively disposed on each input roller 112. In another embodiment, the input drive unit 113 may include a chain connected to the plurality of input rollers 112, a sprocket connected to the chain to rotate the chain, and a motor connected to the sprocket. In yet another embodiment, the input drive unit 113 may include all means and structures that are individually connected to the plurality of input rollers 112 to rotate each input roller 112, or connected to some or all of the plurality of input rollers 112 to rotate the plurality of input rollers 112 simultaneously. However, for ease of explanation, the following detailed description will focus on the case where the input drive unit 113 is disposed on each input roller 112 to rotate each input roller 112.

[0072] The moving part 120 can provide an area for grinding the base material M supplied from the input part 110. The moving part 120 may include a circulating belt 121, a roller 122 for circulating the belt 121, a drive part 123 for driving the roller 122, an anti-deviation part 124 for preventing the belt 121 from deviating, an adjustment part 125 for pressurizing the belt 121, and a cleaning part 126 for cleaning the surface of the belt 121.

[0073] The belt 121 can be rotated by the roller 122, and its position can be changed according to the rotation of the roller 122. In one embodiment, the belt 121 may include an opening 121OP for placing the base material M. In this case, the opening 121OP may be configured corresponding to the first surface S1 of the belt 121, and the shape of the opening 121OP may correspond to the shape of the base material M. In another embodiment, a protective portion may be included on the surface of the belt 121. In this case, the protective portion may be configured on the first surface S1 of the belt 121, and the base material M may be inserted into the protective portion. However, for ease of explanation, the case where the belt 121 includes the opening 121OP will be described in detail.

[0074] The depth d1 of the opening 121OP can be less than or similar to the thickness d2 of the base material M. Preferably, the depth d1 of the opening 121OP can be the same as the thickness d2 of the base material M. Therefore, when the grinding head 140 grinds the edge portion of the base material M, the step between the belt 121 and the base material M can prevent the pressure of the grinding head 140 from concentrating on the edge portion of the base material M.

[0075] When the base material M is placed on the belt 121, the opening 121OP can specify the position of the base material M. Here, specifying the position means that, since the base material M is inserted into the opening 121OP, the position of the base material M does not change relative to the belt 121 due to the grinding process. Therefore, the surface of the base material M can be ground uniformly.

[0076] The strip 121 may include alignment marks AM on the first surface S1 on which the base material M is placed. In one embodiment, the alignment marks AM may be formed by irradiating the first surface S1 of the strip 121 with a laser. In another embodiment, the alignment marks AM may be formed by attaching them to the first surface S1 of the strip 121.

[0077] Multiple alignment marks AM can be configured on the first surface S1. In one embodiment, the alignment marks AM can be configured at a certain interval. The measurement unit 160, which will be described later, can observe the alignment marks AM in the belt 121 to determine whether the belt 121 is misaligned, and can determine the position of the alignment marks AM to input the base material M into the moving unit 120. In addition, the measurement unit 160 can observe the spacing between the alignment marks AM to determine the degree of stretching of the belt 121.

[0078] Alignment markers AM can have various shapes. For example, alignment marker AM can be cross-shaped. As another example, alignment marker AM can be quadrilateral, polygonal, or circular. In this case, the width of alignment marker AM can be 50 μm. In another embodiment, the width of alignment marker AM can be less than 50 μm or more than 50 μm.

[0079] In one embodiment, the belt 121 may include multiple layers. For example, the belt 121 may include a first layer 121a and a second layer 121b. The first layer 121a may be the layer in contact with the roller 122, and the second layer 121b may be the layer on which the base material M is disposed. In this case, the depth d1 of the opening 121OP may be less than the thickness t1 of the second layer 121b.

[0080] The first layer 121a may contain a fiber material. For example, it may contain polyurethane fiber. The second layer 121b may contain a material with excellent chemical resistance. For example, the second layer 121b may contain at least one of unsaturated polyester (UPE) and Teflon. The upper surface of the second layer 121b may be polished by a polishing head 140, preferably using a material with excellent chemical resistance and abrasion resistance.

[0081] In another embodiment, the strip 121 may be a single layer. In this case, the strip 121 may contain a material with excellent chemical resistance. For example, the strip 121 may contain at least one of unsaturated polyester (UPE) and Teflon.

[0082] Roller 122 can rotate to circulate belt 121. For example, roller 122 can rotate about a rotation axis 122X. Multiple rollers 122 can be provided, and the multiple rollers 122 can be arranged to be spaced apart from each other to keep the tension of belt 121 constant.

[0083] The drive unit 123 may include a motor or the like, and may be disposed on the roller 122 to rotate the roller 122 about the rotation axis 122X. In this case, the drive unit 123 may be disposed on at least one of the plurality of rollers 122.

[0084] The anti-offset portion 124 can prevent the belt 121 from shifting. The anti-offset portion 124 can be configured to place the belt 121 between the belt and the belt. For example, the first anti-offset portion 124A and the second anti-offset portion 124B can be configured to place the belt 121 between the belt and the belt. Specifically, the first anti-offset portion 124A and the second anti-offset portion 124B can be configured along a first direction (e.g., the y direction or the -y direction).

[0085] The anti-deviation portion 124 can be configured in the region R where the movement direction of the belt 121 changes. In this case, the region R where the movement direction of the belt 121 changes can be defined as the region where the belt 121 cycles in a second direction (e.g., the x-direction or the -x-direction) and then changes to the opposite direction (e.g., the -x-direction or the x-direction). Alternatively, the region R where the movement direction of the belt 121 changes can be defined as the region where the belt 121 cycles in the opposite direction to the second direction and then changes back to the second direction. In this case, the anti-deviation portion 124 can be configured adjacent to the roller 122. For example, the first anti-deviation portion 124A and the third anti-deviation portion 124C can be configured along a second direction (e.g., the x-direction or the -x-direction) that intersects the first direction. Since the anti-deviation portions 124 are configured at both ends of the belt 121, deviation of the belt 121 can be prevented.

[0086] The anti-deviation portion 124 can be configured to face at least a portion of the side surface of the belt 121, i.e., the second surface S2. In this case, the second surface S2 can be defined as any surface of the belt 121 other than the first surface S1 and the third surface S3 opposite to the first surface S1. Therefore, the anti-deviation portion 124 can guide the belt 121 to circulate along a specific path. Furthermore, since the anti-deviation portion 124 can contact the second surface S2, which is not the first surface S1, damage to the first surface S1 can be prevented.

[0087] The anti-deviation portion 124 can move in a first direction (e.g., the y-direction or -y-direction) parallel to the rotation axis 122X of the roller 122. Specifically, the anti-deviation portion 124 can move linearly in the first direction. On the other hand, the first anti-deviation portion 124A and the second anti-deviation portion 124B can move independently. For example, the first anti-deviation portion 124A and the second anti-deviation portion 124B can move in the same direction. Alternatively, the first anti-deviation portion 124A and the second anti-deviation portion 124B can move in opposite directions.

[0088] The anti-deviation part 124 may include a first roller 124a, a first drive part 124b, and a first spacing adjustment part 124c.

[0089] The first roller 124a may at least partially overlap with the second surface S2 of the belt 121 in a first direction (e.g., the y-direction or the -y-direction). Additionally, the first roller 124a may be rotatably configured. In one embodiment, the first roller 124a may contact the roller 122. In another embodiment, the first roller 124a may be spaced apart from the roller 122. In one embodiment, the first roller 124a may rotate in the opposite direction to the roller 122. For example, this could be when the roller 122 is in… Figure 2 When the first roller 124a rotates clockwise, it is in the middle. Figure 2 Rotate counterclockwise from the center.

[0090] The first drive unit 124b can rotate the first roller 124a. Similar to the drive unit 123, the first drive unit 124b may include a motor or the like and may be disposed on the first roller 124a.

[0091] The first pitch adjustment unit 124c can move the first roller 124a. The first pitch adjustment unit 124c can be connected to the first roller 124a to cause the first roller 124a to move linearly. For example, the first pitch adjustment unit 124c can move the first roller 124a in a first direction (e.g., the y-direction or the -y-direction). The first pitch adjustment unit 124c can be provided in various forms. For example, the first pitch adjustment unit 124c may include a cylinder. As another example, the first pitch adjustment unit 124c may include a ball screw and a motor connected to the ball screw. As yet another example, the first pitch adjustment unit 124c may also include a linear motor. As described above, the first pitch adjustment unit 124c may include all the means and structures capable of causing the first roller 124a to move linearly.

[0092] The adjusting part 125 can apply pressure to the third surface S3 of the belt 121. At this time, the adjusting part 125 can be configured to face the third surface S3. That is, the adjusting part 125 can be disposed between multiple rollers 122. The adjusting part 125 can contact the third surface S3 and apply pressure to the belt 121 to maintain the tension of the belt 121. At this time, since the adjusting part 125 does not apply pressure to the first surface S1 of the belt 121, damage to the first surface S1 can be prevented. In one embodiment, the adjusting part 125 can have at least one. The adjusting part 125 may include a second roller 125a, a second drive part 125b, and second pitch adjusting parts 125c1 and 125c2.

[0093] The second roller 125a can be rotatably configured, and the second drive unit 125b can be connected to the second roller 125a to rotate the second roller 125a. Similar to the first drive unit 124b, the second drive unit 125b may include a motor or the like.

[0094] The second pitch adjustment units 125c1 and 125c2 can move the second roller 125a. The second pitch adjustment units 125c1 and 125c2 can be connected to the second roller 125a to enable linear movement of the second roller 125a. Similar to the first pitch adjustment unit 124c, the second pitch adjustment units 125c1 and 125c2 can include all the means and structures capable of enabling linear movement of the second roller 125a.

[0095] In one embodiment, the second pitch adjustment portions 125c1 and 125c2 may include a first portion 125c1 and a second portion 125c2. In this case, the direction in which the first portion 125c1 linearly moves the second roller 125a and the direction in which the second portion 125c2 linearly moves the second roller 125a may be different. For example, the first portion 125c1 may move the second roller 125a in a third direction (e.g., the z-direction or the -z-direction) that intersects the first and / or second directions. The second portion 125c2 may move the second roller 125a in a second direction (e.g., the x-direction or the -x-direction).

[0096] The cleaning unit 126 can clean the surface of the belt 121. In one embodiment, the cleaning unit 126 may include a third roller 126a, a third drive unit 126b, a third pitch adjustment unit 126c, a first cleaning roller 126d, and a second cleaning roller 126e.

[0097] The third roller 126a, the third drive unit 126b, and the third pitch adjustment unit 126c are similar to the second roller 125a, the second drive unit 125b, and the second pitch adjustment units 125c1 and 125c2, so detailed descriptions are omitted. On the other hand, the third roller 126a can support the belt 121 and the first cleaning roller 126d during the cleaning of the surface of the belt 121 by the first cleaning roller 126d.

[0098] In this embodiment, the first cleaning roller 126d and the second cleaning roller 126e can rotate respectively. The first cleaning roller 126d and the second cleaning roller 126e can be connected to the drive unit and rotate respectively.

[0099] The surfaces of the first cleaning roller 126d and the second cleaning roller 126e can be in contact with each other. At this time, the first cleaning roller 126d and the second cleaning roller 126e can rotate in different directions relative to each other. For example, the first cleaning roller 126d can rotate in... Figure 2 When the middle rotates counterclockwise, the second cleaning roller 126e is in Figure 2 Rotate clockwise from the center.

[0100] The first cleaning roller 126d can clean the surface of the belt 121. Specifically, the first cleaning roller 126d can contact the belt 121 and adsorb the abrasive parts remaining on the surface of the belt 121. In addition, the second cleaning roller 126e can adsorb the abrasive parts adsorbed on the first cleaning roller 126d. At this time, the adsorption force of the second cleaning roller 126e can be greater than the adsorption force of the first cleaning roller 126d. Therefore, even if the abrasive parts are adsorbed on the surface of the first cleaning roller 126d, the second cleaning roller 126e can simultaneously adsorb the abrasive parts adsorbed on the surface of the first cleaning roller 126d, thus maintaining the adsorption force of the first cleaning roller 126d.

[0101] In one embodiment, the cleaning unit 126 may include a third cleaning roller 126f and a fourth cleaning roller 126g. In this case, the third cleaning roller 126f and the fourth cleaning roller 126g may be configured similarly to the first cleaning roller 126d and the second cleaning roller 126e, respectively.

[0102] The third cleaning roller 126f and the fourth cleaning roller 126g can be configured in the region R where the movement direction of the belt 121 changes. In this case, the roller 122 can support the third cleaning roller 126f during the cleaning of the surface of the belt 121 by the third cleaning roller 126f. Therefore, it is not necessary to have a separate third roller 126a, a third drive unit 126b, and a third pitch adjustment unit 126c for supporting the third cleaning roller 126f.

[0103] In one embodiment, the cleaning unit 126 may include all of the third roller 126a, the third drive unit 126b, the third pitch adjustment unit 126c, and the first cleaning rollers 126d to the fourth cleaning rollers 126g. In some embodiments, it may include the third roller 126a, the third drive unit 126b, the third pitch adjustment unit 126c, the first cleaning roller 126d, and the second cleaning roller 126e, but exclude the third cleaning roller 126f and the fourth cleaning roller 126g. In some embodiments, it may include the third cleaning roller 126f and the fourth cleaning roller 126g, but exclude the third roller 126a, the third drive unit 126b, the third pitch adjustment unit 126c, the first cleaning roller 126d, and the second cleaning roller 126e. For ease of explanation, the following detailed description will focus on the case including the third roller 126a, the third drive unit 126b, the third spacing adjustment unit 126c, the first cleaning roller 126d, and the second cleaning roller 126e, but excluding the third cleaning roller 126f and the fourth cleaning roller 126g.

[0104] The moving part 120 may also include a base material support part 127 disposed on the belt 121. The base material support part 127 can support the base material M during surface grinding. At this time, the base material support part 127 can be disposed between a plurality of rollers 122 to correspond to the grinding head 140. This base material support part 127 can be provided in the form of a plate.

[0105] The grinding head 140 can be configured to correspond to the moving part 120. For example, the grinding head 140 can be disposed on the first surface S1 of the belt 121. In this case, the grinding head 140 can move in various directions. For example, the grinding head 140 can move towards... Figure 1 It moves in at least one of the x, y, and z directions.

Hereinafter, the case where the grinding head body 141 is connected to the grinding drive unit 144 to perform linear motion will be described in detail.

[0108] The grinding head rotating part 142 can be rotatably connected to the grinding head body part 141. At this time, the grinding pad 143 can be connected to the grinding head rotating part 142.

[0111] In one embodiment, the first grinding drive unit 144A may include a motor connected to the grinding head rotating unit 142 to rotate the grinding head rotating unit 142. In another embodiment, the first grinding drive unit 144A may include a speed reducer disposed between the motor connected to the grinding head rotating unit 142 and the grinding head rotating unit 142.

[0112] The second grinding drive unit 144B can cause the grinding head body 141 to move linearly. At this time, at least one second grinding drive unit 144B may be provided. For example, multiple second grinding drive units 144B may be provided, and each second grinding drive unit 144B can cause... Figure 1 The grinding head body 141 moves linearly in one of the x, y, or z directions. In this case, the second grinding drive unit 144B can be provided in various forms. For example, the second grinding drive unit 144B may include a cylinder. As another example, the second grinding drive unit 144B may also include a ball screw and a motor connected to the ball screw. As yet another example, the second grinding drive unit 144B may also include a linear motor. As described above, the second grinding drive unit 144B may include all devices and structures connected to the grinding head body 141 that enable the grinding head body 141 to move linearly in various directions.

[0113] In one embodiment, the conveying unit 150 can transport the parent material M to the outside. In another embodiment, the conveying unit 150 may be omitted, and the parent material M may be directly transported to the outside in the moving unit 120. However, the following description will focus on the case where the parent material M is transported to the outside from the conveying unit 150.

[0114] The conveying unit 150 can be configured to convey the ground masterbatch M separately from the moving unit 120. The conveying unit 150 may include a conveying support 151, a conveying roller 152, and a conveying drive 153. In this case, the conveying support 151, the conveying roller 152, and the conveying drive 153 may be the same as or similar to the input support 111, the input roller 112, and the input drive 113.

[0115] The manufacturing apparatus 100 for the display device may also include a measuring unit 160 and a spraying unit 170.

[0116] The measuring unit 160 can observe the alignment mark AM disposed on the first surface S1. Additionally, the measuring unit 160 can observe the base material M disposed on the first surface S1. In one embodiment, multiple measuring units 160 may be provided. In this case, the measuring unit 160 can observe multiple alignment marks AM and the base material M separately. Thus, the degree of offset of the strip 121, the surface condition of the strip 121, and whether the base material M is disposed corresponding to the opening 121OP can be observed. The measuring unit 160 may be a camera or similar imaging device.

[0117] The jetting unit 170 can remove the abrasive components disposed on the alignment mark AM. For example, abrasive components may be disposed on the alignment mark AM before the measuring unit 160 observes it. The abrasive components may obstruct the measuring unit 160 from observing the alignment mark AM. In this case, the jetting unit 170 can jet gas to remove the abrasive components disposed on the alignment mark AM. The jetting unit 170 may be an air blower.

[0118] Figure 5a as well as Figure 5b This is a top view showing a portion of the movable part according to another embodiment of the present invention. Figure 5a as well as Figure 5b In, with Figure 2 The same reference numerals refer to the same parts, therefore repeated descriptions are omitted.

[0119] Reference Figure 5a The moving part 120-1 may include a belt 121, a roller 122, a drive part 123, a cleaning part 126-1, and a base material support part 127.

[0120] The cleaning unit 126-1 can clean the belt 121. The cleaning unit 126-1 may include a fixed roller 126a-1, a cleaning container 126b-1, a cleaning adjustment unit 126c-1, and a washing liquid removal unit 126d-1.

[0121] The fixed roller 126a-1 guides the belt 121 towards the cleaning container 126b-1. This allows the belt 121 to come into contact with the washing liquid in the cleaning container 126b-1. The fixed roller 126a-1 is rotatable. Furthermore, a drive unit can be connected to the fixed roller 126a-1.

[0122] The cleaning container 126b-1 can store cleaning fluid. The cleaning container 126b-1 can be connected to the cleaning adjustment unit 126c-1 to adjust the cleaning fluid. For example, the cleaning adjustment unit 126c-1 can adjust the amount of cleaning fluid inside the cleaning container 126b-1. Additionally, the cleaning adjustment unit 126c-1 can replace the cleaning fluid.

[0123] The washing liquid removal unit 126d-1 can remove the washing liquid remaining on the belt 121. For example, the washing liquid removal unit 126d-1 can be a blade that is in contact with the belt 121. As another example, the washing liquid removal unit 126d-1 can be an evaporator that evaporates the washing liquid or an absorber that absorbs the washing liquid.

[0124] Reference Figure 5b The moving part 120-2 may include a belt 121, a roller 122, a drive part 123, a cleaning part 126-2, and a base material support part 127.

[0125] The cleaning section 126-2 can clean the belt 121. The belt 121 may have the cleaning section 126-2 extending through it. In one embodiment, the cleaning section 126-2 may include a brush. The brush can then be used to remove abrasive components. In another embodiment, the cleaning section 126-2 can spray washing liquid toward the belt 121. The washing liquid may be water. In some embodiments, the cleaning section 126-2 may also include a washing liquid removal section (not shown) for removing the washing liquid.

[0126] On the other hand, the operation of the display device manufacturing apparatus 100 will be described in detail below.

[0127] Figure 6a It is shown Figure 1 The front view of the operation method of the manufacturing apparatus 100 for the display device shown. Figure 6b It is shown Figure 1 A top view of the operation method of the manufacturing apparatus 100 for the display device shown. Figure 7 as well as Figure 8 It is shown Figure 1 The front view of the operation method of the manufacturing apparatus 100 for the display device shown.

[0128] Reference Figure 6a as well as Figure 6b The alignment mark AM disposed on the first surface S1 of the cyclic belt 121 can be observed. At this time, the measuring unit 160 can observe the alignment mark AM. Multiple measuring units 160 can be provided, and multiple measuring units 160 can observe multiple alignment marks AM. For example, multiple measuring units 160 can observe the first alignment mark AM1, the second alignment mark AM2, the third alignment mark AM3, and the fourth alignment mark AM4. Therefore, it is possible to determine whether the cyclic belt 121 is offset, the surface condition of the belt 121, or whether the belt 121 is stretched, etc.

[0129] When the measuring unit 160 observes the alignment mark AM, the abrasive component disposed on the alignment mark AM can be removed. Specifically, the spraying unit 170 can spray the spraying component A onto the surface of the belt 121 to remove the abrasive component. At this time, the spraying component A can be air. For example, when the abrasive component is disposed on the alignment mark AM, the spraying unit 170 can spray the spraying component A onto the first surface S1 of the belt 121 to remove the abrasive component. Therefore, the measuring unit 160 can easily observe the alignment mark AM.

[0130] Next, the positions of alignment marks AM can be compared with the pre-set positions. For example, the positions of the first alignment mark AM1 and the second alignment mark AM2 can be compared with the pre-set positions of the first alignment mark AM1 and the second alignment mark AM2 to determine whether the tape 121 has shifted. Similarly, the positions of the third alignment mark AM3 and the fourth alignment mark AM4 can be compared with the pre-set positions of the third alignment mark AM3 and the fourth alignment mark AM4 to determine whether the tape 121 has shifted. As another example, the positions of the first alignment mark AM1 and the third alignment mark AM3 can be compared with the pre-set positions of the first alignment mark AM1 and the third alignment mark AM3 to determine whether the tape 121 has been stretched.

[0131] Subsequently, if the position of the alignment mark AM differs from the previously set position, the position of the belt 121 can be adjusted using the anti-deviation part 124. Specifically, the anti-deviation part 124 can move in a first direction (e.g., the y-direction or the -y-direction) to contact the belt 121. At this time, the first anti-deviation part 124A and the second anti-deviation part 124B can move independently. For example, in Figure 6bIn this configuration, with the first anti-deviation unit 124A stopped, the second anti-deviation unit 124B can move in the y-direction or the -y-direction. As another example, with the second anti-deviation unit 124B stopped, the first anti-deviation unit 124A can move in the y-direction or the -y-direction. As yet another example, the first anti-deviation unit 124A and the second anti-deviation unit 124B can move in the same direction or in opposite directions.

[0132] The anti-deviation unit 124 can move the belt 121 in a first direction (e.g., the y-direction or the -y-direction). Moving the belt 121 in the first direction means moving a portion of the belt 121 located in the area where the direction of movement of the belt 121 changes. Alternatively, it can mean moving the entire belt 121 in the first direction. Therefore, when the circulation path of the belt 121 changes due to external factors, the anti-deviation unit 124 can restore the circulation path of the belt 121.

[0133] Additionally, pressure can be applied to the third surface S3 of the belt 121 to maintain the tension of the belt 121. Specifically, the adjusting unit 125 can apply pressure to the third surface S3 of the belt 121. Therefore, the tension of the belt 121 can be maintained. In this embodiment, the belt 121 can circulate through the roller 122 and contact the grinding head 140. Therefore, the length of the belt 121 may be stretched during the grinding process. At this time, the adjusting unit 125 can apply pressure to the third surface S3 of the belt 121 to maintain the tension of the belt 121. Since the adjusting unit 125 does not contact the first surface S1 of the belt 121, damage to the first surface S1 can be prevented.

[0134] The base material M can be externally configured into the input unit 110 in various ways. For example, the base material M can be transferred to the input unit 110 via a robotic arm. Alternatively, the user can manually supply the base material M into the input unit 110 using additional equipment.

[0135] The base material M can be directly disposed in the input section 110 or disposed in the input section 110 as a support member (not shown). In this case, the support member can be in the form of a plate, including glass, etc. Hereinafter, for ease of explanation, the case in which the base material M is directly disposed in the input section 110 will be described in detail.

[0136] The base material M can take various forms. For example, the base material M can be used when manufacturing a single display device (not shown). As another example, the base material M can be used when manufacturing multiple display devices. In this case, it can be that after the base material M forms multiple display areas (not shown), it is separated into multiple parts to correspond to each display area.

[0137] The base material M can include various materials. Base material M can include glass, or polymer resins such as polyethersulfone, polyarylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyimide, polycarbonate (PC), cellulose triacetate (TAC), cellulose acetate propionate, etc.

[0138] The measuring unit 160 can observe the base material M and guide it to be fed into the drive unit 113 and drive unit 123, which are linked together. When the drive unit 123 is running, the roller 122 can rotate while the belt 121 rotates.

[0139] The parent material M can be conveyed from the input section 110 to the moving section 120. The parent material M can be placed on the belt 121, and in particular, the parent material M can be configured to correspond to the opening 121OP. At this time, the measuring section 160 can observe the parent material M and guide the parent material M to be placed in the opening 121OP. Therefore, the position of the parent material M can remain relatively unchanged relative to the belt 121.

[0140] Reference Figure 7 The drive unit 123 can be operated to arrange the base material M in a predetermined position. In this case, the base material M can be positioned below the grinding head 140.

[0141] In one embodiment, the operation of the drive unit 123 can be stopped to fix the position of the base material M. Then, the first grinding drive unit 144A and the second grinding drive unit 144B can operate to grind one side of the base material M while the grinding head 140 moves linearly. In another embodiment, one side of the base material M can be ground while the drive unit 123 remains operational. In this case, the base material M can be ground while one side of the base material M moves along a predetermined path (e.g., the x-direction).

[0142] During or before grinding, the grinding component P can be supplied to one side of the base material M. The grinding component P can be supplied in various ways. For example, the grinding component P can be supplied to the base material M through the grinding head 140. Specifically, the grinding component P can be supplied from the outside through a flow channel formed inside the grinding head 140. In this case, the grinding pad 143 can have a hole for supplying the grinding component P. As another example, the grinding component P can also be supplied to one side of the base material M through a grinding component supply section 180 separately provided with the grinding head 140. In this case, the grinding component supply section 180 can be provided in the form of a nozzle. Hereinafter, for ease of explanation, the case where the grinding component supply section 180 is separately provided with respect to the grinding head 140 and the grinding component P is supplied to the base material M before the operation of the grinding head 140 will be described in detail.

[0143] The grinding component P may contain deionized water (DIW), surfactant, and slurry.

[0144] Reference Figure 8 After one side of the base material M is ground, the base material M can be conveyed to the conveying unit 150. At this time, the measuring unit 160 can grasp the position of the base material M to guide the drive unit 123 and the conveying drive unit 153 to work together.

[0145] Additionally, the surface of the belt 121 can be cleaned. Specifically, the abrasive parts P remaining on the surface of the belt 121 can be removed. In one embodiment, the cleaning unit 126 may include a third roller 126a, a third drive unit 126b, a third pitch adjustment unit 126c, a first cleaning roller 126d, and a second cleaning roller 126e. In this case, the first cleaning roller 126d can clean the surface of the belt 121. The second cleaning roller 126e can be connected to the first cleaning roller 126d to adsorb the abrasive parts adsorbed on the first cleaning roller 126d. In this case, the first cleaning roller 126d and the second cleaning roller 126e can rotate in different directions from each other. In another embodiment, the cleaning unit 126 may include... Figure 5a The fixed roller 126a-1, cleaning container 126b-1, cleaning adjustment section 126c-1, and washing liquid removal section 126d-1 shown are used for the cleaning belt 121. In yet another embodiment, as... Figure 5b As shown, the belt 121 may have a through cleaning section 126-2, which cleans the belt 121.

[0146] In this embodiment, the display device manufacturing apparatus 100 may include an anti-displacement section 124 to precisely adjust the belt 121 on which the base material M is placed. Therefore, one side of the base material M can be uniformly flattened.

[0161] An upper electrode Cst2 of a storage capacitor Cst can be disposed above the second gate insulating layer 13b. The upper electrode Cst2 can overlap with the gate electrode 14 below it. In this case, placing the second gate insulating layer 13b between the overlapping gate electrode 14 and the upper electrode Cst2 can form a storage capacitor Cst. That is, the gate electrode 14 can function as the lower electrode Cst1 of the storage capacitor Cst.

[0162] Thus, the storage capacitor Cst and the thin-film transistor TFT can be formed overlappingly. In some embodiments, the storage capacitor Cst can also be formed without overlapping with the thin-film transistor TFT.

The display element layer (DEL) may include an organic light-emitting diode (OLED), and the pixel electrode 21 of the OLED is electrically connected to a thin-film transistor (TFT) through contact holes in the planarized insulating layer 17.
