As used herein, the term "and / or" includes any and all combinations of one or more of the related listed items. Expressions such as "at least one", when following a list of elements, modify the entire list of elements, rather than individual elements in the list.

[0059] Figure 1 is a perspective view of an exemplary embodiment of a device 100 for manufacturing a display device. Figure 2 and Figure 3 is a side view showing Figure 1 the operation of the device 100 for manufacturing a display device shown in

[0060] Referring to Figures 1 to 3 , the device 100 for manufacturing a display device may include a first roller 131, a second roller 132, a third roller 133, a fourth roller 134, a flatness maintainer (not shown), and a sensing unit 180.

[0061] One of the first roller 131 and the second roller 132 may wind the film member TF, and then unwind the film member TF. In addition, the other of the first roller 131 and the second roller 132 may wind the unwound film member TF. In this case, the film member TF may be a transparent material. In an exemplary embodiment, for example, the film member TF may include a synthetic resin.

[0062] At least one of the above-mentioned first roller 131 and second roller 132 may include a roller driver (not shown) that drives at least one of the first roller 131 and the second roller 132. The roller driver may include a speed reducer connected to at least one of the first roller 131 and the second roller 132 and a motor connected to the speed reducer. In another exemplary embodiment, the roller driver may also include a motor connected to at least one of the first roller 131 and the second roller 132.

[0063] The third roller 133 and the fourth roller 134 bend the flexible film member TF. Here, the third roller 133 and the fourth roller 134 can prevent a decrease in the tension of the film member TF. In an exemplary embodiment, for example, the third roller 133 may be arranged above the first roller 131 to bend the film member TF unrolled from the first roller 131. Additionally, the fourth roller 134 may be arranged above the second roller 132 to bend the film member TF wound around the second roller 132. In this case, the rotation centers of the third roller 133 and the fourth roller 134 may be arranged in a straight line, and the portions of the third roller 133 in contact with the film member TF and the portions of the fourth roller 134 in contact with the film member TF may be arranged in the same plane.

[0064] The flatness retainer can flatten the film member TF arranged between the first roller 131 and the second roller 132. The flatness retainer can be provided in various forms. In an exemplary embodiment, for example, the flatness retainer may include a clamping unit 140 that pulls on the side edges of the film member TF. The flatness retainer may include a support chuck 160 arranged below the film member TF and that adsorbs or supports the film member TF.

[0065] The clamping unit 140 as described above can apply a force to the film member TF in a direction (e.g., Figure 1 the Y direction in Figure 1 ) perpendicular to the moving direction of the film member TF (e.g., the X direction in

[0066] ). In this case, the clamping unit 140 can keep the upper surface of the film member TF flat by pulling on the side edges of the film member TF. The clamping unit 140 may include a plurality of holding portions that respectively contact the upper surface and the lower surface of the film member TF. The plurality of holding portions may be arranged to face each other to adjust the distance between the holding portions.

[0067] The support chuck 160 may be arranged and move below the film member TF. The support chuck 160 can move up and down to selectively contact the film member TF. The support chuck 160 may be connected to a support chuck driver 170. The support chuck driver 170 is similar to the above-described clamping driver 150, and thus its detailed description will be omitted.

[0068] The support chuck 160 can simply contact the lower surface of the film member TF to support the film member TF, or can completely adhere to the lower surface of the film member TF to fix the lower surface of the film member TF. In an exemplary embodiment, the support chuck 160 can have a plate shape with a flat upper surface. In another exemplary embodiment, the support chuck 160 can include a vacuum form in which suction holes (not shown) are defined on its outer surface and flow channels (not shown) communicating with the suction holes are arranged therein, and the flow channels are connected to an external suction pump (not shown) or the like to discharge the gas in the flow channels to the outside to adsorb the film member TF through the suction holes. In another exemplary embodiment, the support chuck 160 can also include a porous chuck on whose outer surface a plurality of grooves or holes are defined. Hereinafter, for convenience of description, the support chuck 160 in the form of a vacuum chuck will be described in detail.

[0069] The sensing unit 180 can detect the droplets arranged on the film member TF. Here, the sensing unit 180 can be arranged to face the upper surface or the lower surface of the film member TF. In this case, the sensing unit 180 can include a camera that captures an image of the droplets on the film member TF. Hereinafter, for convenience of description, an exemplary embodiment in which the sensing unit 180 is arranged to face the upper surface of the film member TF will be described in detail.

[0070] Regarding a method of operating the apparatus 100 for manufacturing a display device, as described above, the head unit 120 can be connected to the first linear driver 111 and the second linear driver 112. The second linear driver 112 can be connected to the first linear driver 111 and linearly move in a first direction (e.g., Figure 1 the X direction in Figure 1 ), and the second linear driver 112 can move the head unit 120 in a second direction different from the first direction (e.g.,

[0071] the Y direction in

[0072] First, when the head unit 120 enters the test area, a roller driver (not shown) can be operated to drive at least one of the first roller 131 and the second roller 132. In this case, the film member TF wound around the first roller 131 can be unrolled and moved to the second roller 132. Then, the operation of the roller driver can be stopped, and the film member TF can be arranged between the first roller 131 and the second roller 132.

[0073] When the film member TF stops as described above, the clamping driver 150 operates to move the clamping unit 140 to the side edge of the film member TF, and the clamping unit 140 can grip the side edge of the film member TF.

[0074] After the clamping unit 140 has gripped the side edge of the film member TF as described above, the clamping driver 150 operates to move the clamping unit 140 away from the center of the film member TF. In this case, the distance between the pair of clamping units 140 arranged to face each other can gradually increase.

[0075] When the clamping unit 140 moves as described above, the film member TF can be flattened. Specifically, when only the first roller 131 and the second roller 132 are included, the film member TF may be wrinkled due to the external environment or assembly tolerances during its movement. In this case, when droplets are dropped from the head unit 120 onto the film member TF, it may be difficult to accurately test the pattern because the film member TF has an uneven surface. However, by pulling the side edge of the film member TF by the clamping unit 140, the upper surface of the film member TF can be kept flat.

[0076] Before, during, or after the side edge of the film member TF is pulled by the clamping unit 140, the support chuck 160 can be raised to support the lower surface of the film member TF. In this case, the support chuck driver 170 can be operated to raise the support chuck 160 into contact with the lower surface of the film member TF. In addition, as described above, the film member TF can be completely attached via the suction holes defined in the outer surface of the support chuck 160, and furthermore, the film member TF can be fixed and also kept flat to a certain extent. In this case, after the film member TF is pulled by the clamping unit 140, fixation of the film member TF via the suction holes can be performed.

[0077] When the film member TF is flattened as described above, the head unit 120 can move to discharge droplets onto the film member TF. Here, the material for forming the droplets can be various materials such as organic materials or inorganic materials.

[0078] After the droplet has been dropped onto the film member TF, the sensing unit 180 may detect the droplet on the film member TF. Here, during the fixed state, the sensing unit 180 may detect the droplet. In an alternative exemplary embodiment, after changing the position of the sensing unit 180 to align the sensing unit 180 to face the droplet on the film member TF, the sensing unit 180 may detect the droplet on the film member TF.

[0079] The sensing unit 180 may capture an image of the droplet and, in particular, detect at least one of the size, shape, volume, and position of the droplet. Here, an additional controller (not shown) may calculate or determine at least one of the size, shape, volume, and position of the droplet based on the image of the droplet captured by using the sensing unit 180.

[0080] Based on the result sensed by the sensing unit 180, by comparing one detected item of the size, shape, volume, and position of the droplet with one preset item of the size, shape, volume, and position of the droplet, the controller may control the size, shape, volume, or position of the droplet discharged from the head unit 120.

[0081] After controlling the droplet as described above, the position of the head unit 120 may be changed or the film member TF may be moved again, and then the head unit 120 may discharge the droplet onto the film member TF and may repeat the above operation. Here, when the film member TF is moved, the clamping unit 140 may not hold the film member TF.

[0082] When the droplet discharged from the head unit 120 and arranged (e.g., installed) on the film member TF in the above operation is determined to be consistent with the preset droplet or within the error range, the head unit 120 may move to the processing area to perform processing.

[0083] Therefore, according to the apparatus 100 for manufacturing a display device and the method for manufacturing a display device, the droplet of the head unit 120 can be accurately measured to control the head unit 120. In addition, according to the apparatus 100 for manufacturing a display device and the method for manufacturing a display device, since the upper surface of the film member TF remains flat, at least one of the size, shape, volume, and position of the droplet can be prevented from being deformed due to the shape of the film member TF.

[0084] Figure 4 is a perspective view of an exemplary embodiment of the apparatus 100 for manufacturing a display device. Figure 5 and Figure 6 is a side view showing Figure 4 the operation of the apparatus 100 for manufacturing a display device shown in

[0085] Refer to Figures 4 to 6, an apparatus 100 for manufacturing a display device may include a first roller 131, a second roller 132, a third roller 133, a fourth roller 134, a flatness maintainer (not shown), and a sensing unit 180. Here, the first roller 131, the second roller 132, the third roller 133, and the fourth roller 134 are respectively the same as those described with reference to Figures 1 to 3 and thus their detailed descriptions will be omitted.

[0086] The flatness maintainer may include a clamping unit 140 and a support chuck 160. The clamping unit 140 is the same as that described with reference to Figures 1 to 3 and thus its detailed description will be omitted.

[0087] The support chuck 160 may include a support frame 162 connected to a support chuck driver 170 and a transmission part 161 connected to the support frame 162. A part of the support frame 162 may be open. The transmission part 161 may be arranged in the opening of the support frame 162 to be coupled to the support frame 162. The transmission part 161 may include a transparent material. In an exemplary embodiment, for example, the transmission part 161 may include a transparent synthetic resin such as acrylic or glass.

[0088] The sensing unit 180 may be arranged inside the support chuck 160. The sensing unit 180 may be fixed in the support frame 162 or linearly move in one direction. The sensing unit 180 may detect droplets arranged on the film member TF via the transmission part 161. In this case, the sensing unit 180 may be provided in a form the same as or similar to that described above with reference to Figures 1 to 3 and thus its detailed description will be omitted.

[0089] As described above, the operation of the apparatus 100 for manufacturing a display device may be similar to that described above with reference to Figures 1 to 3 Specifically, a roller driver (not shown) may operate to rotate at least one of the first roller 131 and the second roller 132, and the film member TF may move accordingly.

[0090] Next, the operation of the roller driver may be stopped, and the clamping unit 140 may hold the side edge of the film member TF according to the operation of the clamping driver 150 to pull the film member TF. In addition, the support chuck driver 170 may operate to bring the support chuck 160 into contact with the lower surface of the film member TF. In this case, as described above, the support chuck 160 may contact the film member TF to support the film member TF, or may not only contact the film member TF but also fix the film member TF via vacuum or a similar form.

[0091] Next, the head unit 120 may discharge droplets onto the film member TF, and the sensing unit 180 may detect the droplets on the film member TF. A controller (not shown) may determine at least one of the size, volume, position, and shape of the droplets based on the detection result, and then control the size, shape, volume, or position of the droplets discharged from the head unit 120.

[0092] When it is determined that the droplets discharged from the head unit 120 are identical or similar to a preset droplet, the controller may arrange the head unit 120 in the processing area to perform processing. The first linear driver 111 and the second linear driver 112 may arrange the head unit 120 at various positions according to the process.

[0093] In the processing area, various layers may be formed by using the head unit 120. In an exemplary embodiment, for example, an organic layer or an inorganic layer may be disposed on a substrate (not shown) in the processing area by the head unit 120.

[0094] Therefore, according to the apparatus 100 for manufacturing a display device and the method for manufacturing a display device, the droplets of the head unit 120 can be accurately measured to control the head unit 120. In addition, according to the apparatus 100 for manufacturing a display device and the method for manufacturing a display device, since the upper surface of the film member TF remains flat, at least one of the size, shape, volume, and position of the droplets can be prevented from being deformed due to the shape of the film member TF.

[0095] Figure 7 is a perspective view of an exemplary embodiment of the apparatus 100 for manufacturing a display device. Figure 8 and Figure 9 is a side view showing Figure 7 the operation of the apparatus 100 for manufacturing a display device shown in

[0096] Referring to Figures 7 to 9 , the apparatus 100 for manufacturing a display device may include a first roller 131, a second roller 132, a third roller 133, a fourth roller 134, a flatness maintainer (not shown), and a sensing unit 180. Here, the first roller 131, the second roller 132, the third roller 133, and the fourth roller 134 are respectively the same as those described with reference to Figures 1 to 3 and thus their detailed descriptions will be omitted.

[0097] The flatness maintainer may include a clamping unit 140 and a support chuck 160. The clamping unit 140 and the support chuck 160 are the same as or similar to those described with reference to Figures 4 to 6 and thus their detailed descriptions will be omitted.

[0098] The sensing unit 180 may include a first sensing part 181 arranged to face the upper surface of the film member TF and a second sensing part 182 arranged to face the lower surface of the film member TF. The first sensing part 181 may be arranged to be separated from the upper surface of the film member TF, and the second sensing part 182 may be arranged to be separated from the lower surface of the film member TF. In this case, the first sensing part 181 may be the same as or similar to the sensing unit 180 described above with reference to Figures 1 to 3 and the second sensing part 182 may be the same as or similar to the sensing unit 180 described with reference to Figures 4 to 6 .

[0099] Regarding the operation of the apparatus 100 for manufacturing a display device, as described above, the portion onto which the droplets of the film member TF will be discharged may be arranged between the first roller 131 and the second roller 132 by a roller driver (not shown). Then, the operation of the roller driver is stopped, and the clamping driver 150 operates to hold the side edges of the film member TF through the clamping unit 140 and pull the side edges of the film member TF away from the center of the film member TF.

[0100] The support chuck driver 170 may operate to bring the support chuck 160 into contact with the lower surface of the film member TF. Here, the support chuck 160 may support or fix the film member TF while being in contact with the film member TF.

[0101] At least one of the first linear driver 111 and the second linear driver 112 may operate to position the head unit 120 above the film member TF, and droplets may be discharged onto the film member TF through the head unit 120. Then, the droplets on the film member TF may be detected by the first sensing part 181 and the second sensing part 182. At least one of the position, shape, size, and volume of the droplets on the film member TF may be calculated by the first sensing part 181 and the second sensing part 182 based on the average value of at least one of the detected position, shape, size, and volume of the droplets.

[0102] Then, a controller (not shown) may control the droplets discharged from the head unit 120. In an exemplary embodiment, for example, the controller (not shown) may control the discharge rate, discharge amount, or discharge volume, etc. of the droplets discharged from the head unit 120.

[0103] The above operations may be performed until at least one of the shape, size, position, and volume of the droplets discharged from the head unit 120 is equal to at least one of the shape, size, position, and volume of a preset droplet or corresponds to a set range.

[0104] When the control of the head unit 120 is completed, the head unit 120 may move to a processing area to form at least one of various layers on a substrate (not shown).

[0105] Accordingly, according to the apparatus 100 for manufacturing a display device and the method for manufacturing a display device, the droplets of the head unit 120 can be accurately measured to control the head unit 120. In addition, according to the apparatus 100 for manufacturing a display device and the method for manufacturing a display device, since the upper surface of the film member TF remains flat, deformation of at least one of the size, shape, volume, and position of the droplets due to the shape of the film member TF can be prevented.

[0106] Figure 10 is a perspective view of an exemplary embodiment of the clamping unit 140 of the apparatus 100 for manufacturing a display device.

[0107] Referring to Figure 10 , the apparatus 100 for manufacturing a display device can be the same as or similar to that described above with reference to Figure 1 , Figure 4 or Figure 7 . Here, a plurality of clamping units 140 may be included.

In addition, a pair of the clamping units 140 among the plurality of clamping units 140 may be respectively disposed at two side edges of the film member.

In another exemplary embodiment, the plurality of clamping units 140 may be respectively connected to a plurality of clamping drivers (not shown) to linearly move synchronously with each other and correspondingly simultaneously.

[0110] Figures 11 to 14 is a side view showing another exemplary embodiment of the operation of the apparatus 100-1 for manufacturing a display device.

[0111] Referring to Figures 11 to 14 , the apparatus 100-1 for manufacturing a display device may include a first roller 131-1, a second roller 132-1, a third roller 133-1, a fourth roller 134-1, a flatness maintainer (not shown), and a sensing unit 180-1. Here, the first roller 131-1, the second roller 132-1, the third roller 133-1, the fourth roller 134-1, and the sensing unit 180-1 are respectively the same as those described with reference to Figures 1 to 3 , and thus their detailed descriptions will be omitted.

[0112] The flatness maintainer may include a gas injection unit 191-1 and a support chuck 160-1. Here, the support chuck 160-1 may be the same as or similar to that described above with reference to Figures 1 to 3 the description.

[0113] The gas injection unit 191-1 may be arranged to face the upper surface of the film member TF. The gas injection unit 191-1 may be arranged between the first roller 131-1 and the second roller 132-1 to inject an inert gas onto the film member TF.

[0114] In the gas injection unit 191-1, a flow channel connected to the inert gas and injection holes (not shown) may be arranged. The injection holes are connected to the flow channel and the inert gas is injected to the outside through the injection holes. In this case, the gas injection unit 191-1 may be connected to an inert gas supplier that supplies external inert gas. In the above case, the inert gas supplied from the inert gas supplier may be injected from the gas injection unit 191-1 to the film member TF through the injection holes.

[0115] The gas injection unit 191-1 as described above may be connected to a third linear driver 192-1 and a fourth linear driver 193-1. The third linear driver 192-1 may move the gas injection unit 191-1 up and down. The third linear driver 192-1 is connected to the fourth linear driver 193-1, and the fourth linear driver 193-1 may linearly move the third linear driver 192-1.

[0116] The sensing unit 180-1 may include a sensing driver 194-1. The sensing driver 194-1 may linearly move the sensing unit 180-1. In an exemplary embodiment, the sensing driver 194-1 may be provided in various forms, such as a linear motor, a ball screw, and a motor, etc.

[0117] Regarding the operation of the apparatus 100-1 for manufacturing a display device as described above, a roller driver (not shown) may operate to rotate at least one of the first roller 131-1 and the second roller 132-1. Then, when the operation of the roller driver stops, a part of the film member TF may be arranged between the first roller 131-1 and the second roller 132-1.

[0118] Next, the third linear driver 192-1 and the fourth linear driver 193-1 can arrange the gas injection unit 191-1 on the upper surface of the film member TF. The gas injection unit 191-1 can inject an inert gas onto the upper surface of the film member TF arranged between the first roller 131-1 and the second roller 132-1. When the gas injection unit 191-1 injects the inert gas and the upper surface of the film member TF wrinkles, the wrinkles can be flattened. The gas injection unit 191-1 can inject the inert gas from the center of the film member TF toward one side of the film member TF.

[0119] After the film member TF is flattened, the support chuck driver 170-1 can be operated to bring the support chuck 160-1 into contact with the lower surface of the film member TF. In this case, the gas injection unit 191-1 can stop operating. In addition, the third linear driver 192-1 and the fourth linear driver 193-1 can move the gas injection unit 191-1 from the upper surface of the film member TF to another position.

[0120] When the support chuck 160-1 contacts the lower surface of the film member TF, the support chuck 160-1 can be configured as a vacuum chuck or a porous chuck to fix the lower surface of the film member TF.

[0121] After the lower surface of the film member TF is fixed to the support chuck 160-1, the first linear driver 111-1 and the second linear driver 112-1 can be operated to arrange the head unit 120-1 in the test area. Here, the gas injection unit 191-1, the first linear driver 111-1, and the second linear driver 112-1 can not interfere with each other.

[0122] After the head unit 120-1 has discharged droplets onto the film member TF, when the droplets are arranged on the upper surface of the film member TF, the sensing unit 180-1 can detect at least one of the shape, position, size, and volume of the droplets on the film member TF. The sensing unit 180-1 can be linearly moved via the sensing driver 194-1 to the portion where the droplets arranged on the film member TF are located.

[0123] As described above, the droplets discharged from the head unit 120-1 can be controlled based on the detection results. Then, when the head unit 120-1 discharges droplets that are the same as or similar to the preset droplets, the first linear driver 111-1 and the second linear driver 112-1 can move the head unit 120-1 from the test area to the processing area. The head unit 120-1 can discharge droplets onto a substrate (not shown) to form at least one of various layers on the substrate (not shown) in the processing area.

[0124] Accordingly, according to the apparatus 100-1 for manufacturing a display device and the method for manufacturing a display device, the droplets of the head unit 120-1 can be accurately measured to control the head unit 120-1. In addition, according to the apparatus 100-1 for manufacturing a display device and the method for manufacturing a display device, since the upper surface of the film member TF remains flat, deformation of at least one of the size, shape, volume, and position of the droplets due to the shape of the film member TF can be prevented.

[0125] Figures 15 to 18 FIG. 4 is a side view showing another exemplary embodiment of the operation of the apparatus 100-1 for manufacturing a display device.

[0126] Referring to Figures 15 to 18 , the apparatus 100-1 for manufacturing a display device may include a first roller 131-1, a second roller 132-1, a third roller 133-1, a fourth roller 134-1, a flatness maintainer (not shown), a sensing unit 180-1, a third linear driver 192-1, and a fourth linear driver 193-1. The first roller 131-1, the second roller 132-1, the third roller 133-1, the fourth roller 134-1, the third linear driver 192-1, and the fourth linear driver 193-1 are respectively the same as those described above with reference to Figures 11 to 14 and thus a detailed description thereof will be omitted.

[0127] The flatness maintainer may include a gas injection unit 191-1 and a support chuck 160-1. Here, the gas injection unit 191-1 may be the same as or similar to that described above with reference to Figures 11 to 14 . The support chuck 160-1 may include a support frame 162-1 and a transmission part 161-1. The support frame 162-1 and the transmission part 161-1 may be the same as or similar to those described above with reference to Figure 4 and thus a detailed description thereof will be omitted.

[0128] The sensing unit 180-1 may be arranged inside the support frame 162-1. A sensing driver 194-1 may be arranged in the support frame 162-1 to linearly move the sensing unit 180-1. Although not shown in the figure, the sensing driver 194-1 and the sensing unit 180-1 may also be arranged outside the support frame 162-1. In this case, the sensing driver 194-1 may be arranged so as not to overlap the movement range of the support frame 162-1.

[0129] Regarding the operation of the apparatus 100-1 for manufacturing a display device, when a roller driver (not shown) operates, the first roller 131-1 and the second roller 132-1 operate to arrange the portion of the film member TF on which droplets are to be arranged between the first roller 131-1 and the second roller 132-1.

[0130] Next, the third linear driver 192-1 and the fourth linear driver 193-1 can be operated to arrange the gas injection unit 191-1 on the upper surface of the film member TF. The gas injection unit 191-1 can prevent the film member TF from wrinkling by injecting an inert gas onto the upper surface of the film member TF, and can flatten the wrinkled portion of the film member TF. The gas injection unit 191-1 can inject an inert gas onto the film member TF while the film member TF is moving, or can inject an inert gas onto the film member TF after the film member TF is fixed.

[0131] Next, the third linear driver 192-1 and the fourth linear driver 193-1 can be operated to remove the gas injection unit 191-1 from the upper surface of the film member TF. Additionally, the support chuck driver 170-1 can be operated to bring the support chuck 160-1 into contact with the film member TF and then fix the film member TF to the support chuck 160-1. The support chuck 160-1 can be configured as a vacuum chuck or a porous chuck to fix the film member TF.

[0132] After the first linear driver 111-1 and the second linear driver 112-1 are operated to arrange the head unit 120-1 in the test area, the head unit 120-1 can discharge droplets onto the film member TF. Next, the sensing driver 194-1 can be operated to adjust the position of the sensing unit 180-1, and then the droplets on the film member TF can be sensed using the sensing unit 180-1. Additionally, the amount, shape, size, or the like of the droplets discharged from the head unit 120-1 can be controlled based on the result of the detection by the sensing unit 180-1.

[0133] Therefore, according to the apparatus 100-1 for manufacturing a display device and the method for manufacturing a display device, the droplets of the head unit 120-1 can be accurately measured to control the head unit 120-1. Additionally, according to the apparatus 100-1 for manufacturing a display device and the method for manufacturing a display device, since the upper surface of the film member TF remains flat, deformation of at least one of the size, shape, volume, and position of the droplets due to the shape of the film member TF can be prevented.

[0134] Figures 19 to 22 is a side view showing another exemplary embodiment of the operation of the apparatus 100-1 for manufacturing a display device.

[0135] Refer to Figures 19 to 22, the apparatus 100-1 for manufacturing a display device may include a first roller 131-1, a second roller 132-1, a third roller 133-1, a fourth roller 134-1, a flatness maintainer (not shown), a sensing unit 180-1, a third linear driver 192-1, and a fourth linear driver 193-1. The first roller 131-1, the second roller 132-1, the third roller 133-1, the fourth roller 134-1, the third linear driver 192-1, and the fourth linear driver 193-1 are respectively consistent with those described above with reference to Figures 11 to 14 and thus their detailed descriptions will be omitted.

[0137] The sensing unit 180-1 may include a first sensing part 181-1 arranged to face the upper surface of the film member TF and a second sensing part 182-1 arranged to face the lower surface of the film member TF. The first sensing part 181-1 may be connected to a first sensing driver 194-1a to linearly move, and the second sensing part 182-1 may be connected to a second sensing driver 194-1b to linearly move. In this case, the second sensing part 182-1 and the second sensing driver 194-1b may be arranged in the support chuck 160-1.

[0138] Regarding the operation of the apparatus 100-1 for manufacturing a display device, as described above, at least one of the first roller 131-1 and the second roller 132-1 may be operated via a roller driver (not shown) to arrange the portion of the film member TF on which the liquid supply droplet is dropped between the first roller 131-1 and the second roller 132-1.

[0139] Subsequently, the third linear driver 192-1 and the fourth linear driver 193-1 may be operated to arrange the gas injection unit 191-1 on the upper surface of the film member TF and inject an inert gas onto the film member TF, thereby flattening the upper surface of the film member TF.

[0140] The third linear driver 192-1 and the fourth linear driver 193-1 may remove the gas injection unit 191-1 from the upper surface of the film member TF, and the support chuck driver 170-1 may raise the support chuck 160-1 to support the lower surface of the film member TF. The support chuck 160-1 may adsorb the lower surface of the film member TF to fix the film member TF.

[0141] The first linear driver 111-1 and the second linear driver 112-1 can position the head unit 120-1 on the upper surface of the film member TF, and then the head unit 120-1 can drop liquid droplets onto the film member TF.

[0142] Subsequently, the first sensing unit 181-1 and the second sensing unit 182-1 can detect the liquid droplets on the film member TF. The head unit 120-1 can adjust the volume, size, shape, etc. of the dropped liquid droplets based on the detection result.

[0143] When the above adjustment is completed, the first linear driver 111-1 and the second linear driver 112-1 can move the head unit 120-1 to the processing area. Subsequently, the head unit 120-1 can form at least one of various layers on a substrate (not shown).

[0144] Therefore, according to the apparatus 100-1 for manufacturing a display device and the method for manufacturing a display device, the liquid droplets of the head unit 120-1 can be accurately measured to control the head unit 120-1. In addition, according to the apparatus 100-1 for manufacturing a display device and the method for manufacturing a display device, since the upper surface of the film member TF remains flat, deformation of at least one of the size, shape, volume, and position of the liquid droplets due to the shape of the film member TF can be prevented.
