[0036] Features of the various embodiments of this disclosure may be combined or integrated with each other in part or in whole, and may be interlocked and operated in various technical ways, and these embodiments may be performed independently or in relation to each other.

[0037] In the following, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 This is a schematic cross-sectional view of a display device according to an exemplary embodiment of the present disclosure.

[0039] First, the display device 100 according to the exemplary embodiments of this disclosure is a display device capable of displaying images even in a bent or stretched state, and may also be referred to as a stretchable display device, a flexible display device, and an extendable display device. Compared with general display devices of the prior art, the display device 100 can not only have high flexibility, but also stretchability. Therefore, the user can bend or stretch the display device 100, and can freely change the shape of the display device 100 according to the user's manipulation. For example, when the user pulls the display device 100 by holding the end of the display device, the display device 100 can be stretched in the direction of the user's pulling. Alternatively, when the user places the display device 100 on an uneven outer surface, the display device 100 can bend according to the shape of the outer surface of the wall portion. Furthermore, when the force applied by the user is removed, the display device 100 can return to its original shape.

[0040] refer to Figure 1 The display device 100 according to an exemplary embodiment of the present disclosure includes a lower substrate 111, a pattern layer 120, transistors 150 and 160, a light-emitting diode 170, a polarizing plate 200, and an upper substrate 112.

[0041] The lower substrate 111 and the upper substrate 112 are other configured components that support and protect the display device 100. The light-emitting diode 170 can emit light in response to the control of transistors 150 and 160, thereby displaying an image on the front surface of the display device 100. The polarizer 200 suppresses external light reflection to improve the visibility of the display device 100.

[0042] In the following text, reference will be made to Figures 2 to 4 A detailed description of a display device 100 according to an exemplary embodiment of the present disclosure.

[0043] Figure 2 This is a plan view of a display device according to an exemplary embodiment of the present disclosure. Figure 3 yes Figure 2 A schematic enlarged plan view of region A shown. Figures 4 to 6 It is along Figure 3 A cross-sectional view taken from IV-IV'.

[0044] refer to Figures 2 to 4 The lower substrate 111 supports various components of the display device 100, and the upper substrate 112 can cover various components in the display device 100.

[0045] The lower substrate 111 and upper substrate 112, serving as flexible substrates, can be made of bendable or stretchable insulating materials. For example, the lower substrate 111 and upper substrate 112 can be formed of silicone rubber such as polydimethylsiloxane (PDMS) or elastomers such as polyurethane (PU) or polytetrafluoroethylene (PTFE), thus possessing flexibility. Furthermore, the materials of the lower substrate 111 and upper substrate 112 can be the same, but are not limited to this, and can vary.

[0046] The lower substrate 111 and the upper substrate 112 are flexible substrates, which can reversibly expand and contract.

[0047] The lower substrate 111 may include an effective area AA for displaying an image and an ineffective area AA other than the effective area AA. The effective area AA is the area in the display device 100 where the image is displayed. Components for driving the plurality of pixels PX disposed in the effective area AA are disposed in the ineffective area AA.

[0048] The lower substrate 111 can also be defined as including a plurality of rigid regions RA and a stretchable region SA. The plurality of rigid regions RA can be spaced apart from each other. The plurality of rigid regions RA can be regions on the lower substrate 111 that overlap with a plurality of first plate patterns 121 and a plurality of second plate patterns 123. The plurality of rigid regions RA can be regions in which the plurality of first plate patterns 121 and the plurality of second plate patterns 123 are arranged to be rigid.

[0049] The stretchable region SA can be the region surrounding each of the plurality of rigid regions RA. The stretchable region SA can be the region that does not overlap with the plurality of first plate patterns 121 and the plurality of second plate patterns 123. The stretchable region SA is the region between the plurality of first plate patterns 121 and the plurality of second plate patterns 123, and may include the region in which a plurality of first line patterns 122 and a plurality of second line patterns 124 are arranged. Furthermore, the stretchable region SA may include the region in which no pattern layer 120 is provided. The stretchable region SA may be the region in which the plurality of first plate patterns 121 and the plurality of second plate patterns 123 are not configured to be flexibly deformable.

[0050] Therefore, multiple first plate patterns 121 and multiple second plate patterns 123 are provided in multiple rigid regions RA, while multiple first plate patterns 121 and multiple second plate patterns 123 are not provided in the stretchable region SA, so that the multiple rigid regions RA can have greater rigidity than the stretchable region SA.

[0051] Meanwhile, the effective area AA, the ineffective area AA, the stretchable area SA and the multiple rigid areas RA are not limited to the lower substrate 111, but can be mentioned for the entire display device 100.

[0052] Next, a pattern layer 120 is formed on the lower substrate 111. The pattern layer 120 includes a plurality of first plate patterns 121 and a plurality of first line patterns 122 formed in the effective area AA, and a plurality of second plate patterns 123 and a plurality of second line patterns 124 formed in the non-effective area AA.

[0053] The plurality of first plate patterns 121 and the plurality of second plate patterns 123 may be substrates on which configurations such as pixels (PX), gate drivers (GD), and power supplies (PS) are formed. The plurality of first plate patterns 121 and the plurality of second plate patterns 123 may be arranged in the form of individual islands. The plurality of first plate patterns 121 and the plurality of second plate patterns 123 are spaced apart from each other and arranged on the lower substrate 111. For example, the plurality of first plate patterns 121 and the plurality of second plate patterns 123 may be arranged in a matrix, but are not limited thereto. Meanwhile, although in Figure 2 The diagram shows multiple first plate patterns 121 and multiple second plate patterns 123 having rectangular shapes, but their shapes are not limited to these.

[0054] Multiple first line patterns 122 connect adjacent first plate patterns 121, and multiple second line patterns 124 can connect adjacent first plate patterns 121 and second plate patterns 123 or multiple adjacent second plate patterns 122. The multiple first line patterns 122 and multiple second line patterns 124 can have a wavy shape, such as a sine wave shape, but are not limited thereto.

[0055] The plurality of first plate patterns 121, the plurality of first line patterns 122, the plurality of second plate patterns 123, and the plurality of second line patterns 124 can be rigid patterns. For example, the plurality of first plate patterns 121, the plurality of first line patterns 122, the plurality of second plate patterns 123, and the plurality of second line patterns 124 can have greater rigidity than the lower substrate 111 and the upper substrate 112. Therefore, the elastic modulus and hardness of the plurality of first plate patterns 121, the plurality of first line patterns 122, the plurality of second plate patterns 123, and the plurality of second line patterns 124 can be higher than the elastic modulus or hardness of the lower substrate 111. For example, the elastic modulus of the plurality of first plate patterns 121, the plurality of first line patterns 122, the plurality of second plate patterns 123, and the plurality of second line patterns 124 can be 1000 times higher than the elastic modulus of the lower substrate 111 and the upper substrate 112, but is not limited thereto.

[0056] Multiple first plate patterns 121, multiple first line patterns 122, multiple second plate patterns 123 and multiple second line patterns 124 can be formed from a plastic material with lower flexibility than the lower substrate 111 and the upper substrate 112.

[0057] refer to Figure 2 and Figure 3 Pixels PX, comprising multiple sub-pixels, are disposed on multiple first plate patterns 121. Each of the multiple sub-pixels may include a light-emitting diode 170 and circuitry for driving the light-emitting diode 170.

[0058] Multiple pixels can be connected to multiple connection lines 180. That is, multiple pixels can be electrically connected to a first connection line 181 extending along a first direction X and a second connection line 182 extending along a second direction Y.

[0059] refer to Figure 2 The gate driver GD can be mounted on multiple second board patterns 123. The gate driver GD is a component that supplies gate voltage to multiple pixels PX disposed in the effective region AA. For example, the gate driver GD includes multiple stages formed on the multiple second board patterns 123, and each stage of the gate driver GD can be electrically connected to each other via multiple connection lines 180. Therefore, the gate voltage output from any stage can be transferred to another stage. Furthermore, each stage can sequentially supply gate voltage to multiple pixels PX connected to each stage.

[0060] A power supply PS can be mounted in multiple second board patterns 123. The power supply PS can be electrically connected to the gate driver GD and multiple pixels PX. For example, the power supply PS can supply gate drive voltage and gate clock voltage to the gate driver GD. In addition, the power supply PS is connected to multiple pixels PX, supplying pixel drive voltage to each pixel PX.

[0061] A printed circuit board (PCB) includes a controller, such as an IC chip or circuit unit and / or memory or processor, for transmitting signals and voltages used to drive display elements from the controller to the display elements. The PCB may include stretchable and non-stretchable areas to ensure scalability. For example, IC chips, circuit units, memory, and processors can be mounted in the non-stretchable areas, while wiring electrically connected to the IC chips, circuit units, memory, and processors can be provided in the stretchable areas.

[0062] The data driver DD is a component that supplies data voltage to multiple pixels PX located in the active area AA. The data driver DD is configured as an IC chip, and therefore can also be called a data integrated circuit D-IC.

[0063] refer to Figure 4 A first adhesive layer AD1 is disposed between the lower substrate 111 and the pattern layer 120. The first adhesive layer AD1 can bond the lower substrate 111 and the pattern layer 120. For example, the first adhesive layer AD1 can be an optically clear adhesive (OCA), and can be composed of an acrylic-based adhesive, a silicone-based adhesive, and a urethane-based adhesive.

[0064] Multiple light-emitting diodes 170 are disposed on multiple first plate patterns 121. The light-emitting diodes 170 can be either light-emitting diodes (LEDs) or micro LEDs. However, organic light-emitting diodes (OLEDs) are also used as light-emitting diodes 170, but are not limited thereto. Each of the multiple first plate patterns 121 includes an emission region EA, in which multiple light-emitting diodes 170 are disposed.

[0065] Furthermore, even if not shown in the figures, multiple circuits and wirings for driving the multiple light-emitting diodes 170 can be arranged together on multiple first board patterns 121. For example, the multiple circuits may include elements such as driving transistors, switching transistors, and storage capacitors. For example, depending on the circuit configuration, the multiple wirings may include gate lines, data lines, high-potential voltage lines, low-potential voltage lines, and reference voltage lines.

[0066] Connecting lines 180 are disposed on a plurality of first line patterns 122. Connecting lines 180 refer to wiring that electrically connects to pads above the plurality of first board patterns 121. Furthermore, connecting lines 180 can extend from the plurality of first line patterns 122 onto the plurality of first board patterns 121 to electrically connect to pads on the plurality of first board patterns 121. In the region between the plurality of first board patterns 121, the first line patterns 122 are not disposed in areas where connecting lines 180 are not provided.

[0067] The connecting line 180 includes a first connecting line 181 and a second connecting line 182. The first connecting line 181 and the second connecting line 182 are disposed between a plurality of first board patterns 121. Specifically, the first connecting line 181 refers to the wiring in the connecting line 180 extending along a first direction X between the plurality of first board patterns 121. The second connecting line 182 refers to the wiring in the connecting line 180 extending along a second direction Y between the plurality of first board patterns 121. For example, the connecting line 180 may include various metallic materials.

[0068] In typical display devices, various wirings, such as multiple gate lines and multiple data lines, extend in straight lines between multiple sub-pixels, and multiple sub-pixels are connected to a single signal line. Therefore, in typical display devices, various wirings, such as gate lines, data lines, high-potential voltage lines, and reference voltage lines, extend from one side of the display device to the other without being interrupted on the substrate.

[0069] In contrast, in the display device 100 according to an exemplary embodiment of the present disclosure, various wirings that are considered to be used in conventional display devices, such as gate lines, data lines, high-potential voltage lines, reference voltage lines, and initialization voltage lines with straight lines, are provided only on a plurality of first plate patterns 121 and a plurality of second plate patterns 123.

[0070] Furthermore, in the display device 100 according to an exemplary embodiment of the present disclosure, pads on two adjacent first board patterns 121 can be connected by a connecting line 180. For example, gate lines can be provided on a plurality of first board patterns 121 arranged adjacent to each other along a first direction X, and gate pads can be provided at both ends of the gate lines. In this case, the plurality of gate pads on the plurality of first board patterns 121 adjacent to each other in the first direction X can be connected to each other by a first connecting line 181. Therefore, the gate lines provided on the plurality of first board patterns 121 and the first connecting line 181 provided on the first line pattern 122 can be used as a single gate line.

[0071] Therefore, among all the various wirings that can be included in the display device 100, as described above, wirings extending in the first direction X, such as transmit signal lines, low-potential voltage lines, and high-potential voltage lines, can also be electrically connected via the first connecting line 181. Furthermore, the second connecting line 182 can connect to pads on a plurality of first board patterns 121 arranged adjacent to each other in the second direction Y. For example, the second connecting line 182 can connect to pads of data lines, high-potential voltage lines, low-potential voltage lines, or reference voltage lines, but is not limited thereto.

[0072] A second adhesive layer AD2 is provided covering the front surface of the lower substrate 111. The second adhesive layer AD2 can bond the polarizer 200 to the lower substrate 111. The second adhesive layer AD2 can fill the space between the upper substrate 112 and the lower substrate 111. The second adhesive layer AD2 can be formed by coating the front surface of the lower substrate 111 with a material constituting the second adhesive layer AD2 and then curing it. For example, the second adhesive layer AD2 can be an optically transparent adhesive (OCA) and can be composed of acrylic adhesives, silicone adhesives, and polyurethane adhesives.

[0073] The upper substrate 112 is a substrate that supports various components disposed below the upper substrate 112. The upper substrate 112 may be disposed on the polarizing plate 200. The upper substrate 112 is configured to cover the polarizing plate 200, the second adhesive layer AD2, the pattern layer 120, and the components on the pattern layer 120.

[0074] A polarizing plate 200 is disposed between the second adhesive layer AD2 and the upper substrate 112. The polarizing plate 200 can be used to polarize light incident from outside the display device 100 to reduce external light reflection. Furthermore, the polarizing plate 200 includes a black pattern to improve the black brightness of the display device 100. The polarizing plate 200 includes multiple polarizing patterns PP, a black pattern BP surrounding the multiple polarizing patterns PP, and a tear line TL.

[0075] The polarization pattern PP is a configuration that reduces external light reflection and can be used as a polarizing plate 200. The polarizing plate 200 is disposed on a plurality of light-emitting diodes 170. The plurality of polarization patterns PP suppress external light incident on a plurality of pixels PX from being reflected by various metallic materials of the plurality of pixels PXs and then guided to the outside again. The plurality of polarization patterns PP suppress external light reflection to improve the visibility of the display device 100.

[0076] Multiple polarization patterns PP can be disposed on multiple pixels PX. Multiple polarization patterns PP can be disposed in multiple rigid regions RA on which the multiple pixels PX are formed. When the display device 100 is stretched, the polarization patterns PP disposed in the rigid regions RA will not deform and can maintain the same size. The multiple polarization patterns PP are spaced apart from each other and can be arranged in a matrix. The multiple polarization patterns PP can be arranged to overlap with the multiple rigid regions RA. Each of the multiple polarization patterns PP can be arranged to overlap with at least one emission region EA of each of the multiple first plate patterns 121. The polarization patterns PP can be formed to be larger than the emission region EA. The polarization patterns PP can be formed to have a size equal to or smaller than the rigid region RA. The size of the polarization patterns PP can be formed within the range of the size of the emission region EA and the size of the rigid region RA.

[0077] For example, refer to Figure 4 The polarization pattern PP is formed to have the same size as the rigid region RA, so that only the polarization pattern PP can be set in the rigid region RA. For example, refer to Figure 6 The polarization pattern PP is formed smaller than the rigid region RA, allowing the polarization pattern PP and the black pattern BP to be disposed within the rigid region RA. The polarization pattern PP has the same dimensions as the first plate pattern 121. The polarization pattern PP has dimensions larger than the emission region EA and smaller than the first plate pattern 121.

[0078] The black pattern BP can be configured as a black matrix while reducing external light reflection. The black pattern BP can be configured to overlap with the stretchable region SA. In some embodiments, the black pattern BP can be disposed within the stretchable region SA, such as... Figure 4 and Figure 5 As shown. When the display device 100 is stretched, the black pattern BP set in the stretchable area SA can also be stretched. Figure 4 As shown, in the stretchable region SA, a black pattern BP can be arranged to surround multiple rigid regions RA. The black pattern BP can be formed with a shape corresponding to the stretchable region SA, such as a mesh. The black pattern BP disposed in the region between multiple pixels PX can serve as a black matrix. In some embodiments, a portion of the black pattern BP can extend from the stretchable region SA to the rigid region RA, such as... Figure 6 As shown.

[0079] The tear line TL is a component used to divide the polarizing plate 200 into multiple sections, and can form a gap between the polarizing pattern PP and the black pattern BP. The tear line TL is a cut portion that cuts a part of the polarizing plate 200. That is, the polarizing pattern PP of the rigid region RA can be separated from at least a portion of the black pattern BP of the stretchable region SA by the tear line TL.

[0080] The tear line TL can be configured as a polarization pattern PP surrounding the rigid region RA. For example, the tear line TL can be positioned along the periphery of the rigid region RA within the stretchable region SA. The tear line TL is located in the boundary between the stretchable region SA and the rigid region RA, or within the stretchable region SA. Depending on the process margin, the tear line TL can be positioned in the boundary between the stretchable region SA and the rigid region RA, or within the stretchable region SA adjacent to the boundary between the stretchable region SA and the rigid region RA. For example, refer to... Figure 3 , Figure 4 and Figure 6 The tear line TL can be set to pass through the black pattern BP in the stretchable area SA. (See reference) Figure 5 The tear line TL can be configured to pass through the polarizer 200 at the boundary between the stretchable region SA and the rigid region RA. (Reference) Figure 6 The width of the tear line TL on one surface of the polarizing plate 200 is different from the width of the tear line TL on the opposite surface of the polarizing plate 200.

[0081] However, the tear line TL may not be located in the rigid region RA. If the tear line TL is located in the rigid region RA, various metals located in the rigid region RA may not be blocked, leading to external light reflection and leakage, thus reducing display quality. Furthermore, a portion of the polarizing pattern PP connected to the black pattern BP in the stretchable region SA may be affected by the stretching deformation of the black pattern BP, and its effectiveness in blocking external light may be reduced. Therefore, the tear line TL is located at the boundary between the rigid region RA and the stretchable region SA, or within the stretchable region SA, to minimize deformation of the polarizing pattern PP and light leakage caused by the tear line TL.

[0082] Furthermore, depending on the size of the polarization pattern PP and the location of the tear line TL, at least a portion of the black pattern BP can be attached to the periphery of the polarization pattern PP. When the tear line TL is located in the stretchable region SA or the polarization pattern PP has a size smaller than that of the rigid region RA, the black pattern BP can be attached to the edge of the polarization pattern PP.

[0083] For example, such as Figure 3 and Figure 4As shown, when the polarization pattern PP has the same size as the rigid region RA and the tear line TL is located in the stretchable region SA, a portion of the black pattern BP can be attached to the edge of the polarization pattern PP.

[0084] The second adhesive layer AD2 is filled in the tear line TL. The second adhesive layer AD2 is configured to surround the lower and side portions of the polarization pattern PP to fix the polarization pattern PP. When the display device 100 is stretched, fixing the second adhesive layer AD2 of the polarization pattern PP can minimize the deformation of the polarization pattern PP in the rigid region RA.

[0085] Next, refer to Figures 4 to 6 The polarization pattern PP includes a retardation layer 211, a linear polarization layer 212, and an alignment film 214.

[0086] A retardation layer 211 is disposed on the second adhesive layer AD2. The retardation layer 211 delays the phase of linearly polarized light incident from the outside via the linear polarization layer 212. For example, the retardation layer 211 can be a quarter-wave plate (QWP), which delays the phase of the linearly polarized light from the linear polarization layer 212 by 45 degrees. Therefore, the retardation layer 211 delays the phase of the linearly polarized light to change it into circularly polarized light.

[0087] A linear polarization layer 212 is disposed on the retardation layer 211. The linear polarization layer 212 transmits only light from a specific direction of incident light from the outside and absorbs light from other directions. For example, when natural light is incident on the linear polarization layer 212, only linearly polarized light vibrating in a specific direction can pass through the linear polarization layer 212. For example, when the linear polarization layer 212 has a transmission axis of 90 degrees, light vibrating in the direction of the transmission axis passes through the linear polarization layer 212, while light vibrating in a direction different from the transmission axis cannot pass through the linear polarization layer 212.

[0088] Therefore, natural light incident on the display device 100 from the outside is linearly polarized by the linear polarization layer 212, while the linearly polarized external light is circularly polarized by the retardation layer 211. Furthermore, the circularly polarized external light is reflected by various components of the display device 100 to be guided to the polarizing plate 200, and can be linearly polarized by the retardation layer 211 at 0 degrees or 180 degrees. However, external light with linear polarization of 0 degrees or 180 degrees is light along a direction different from the 90-degree transmission axis of the linear polarization layer 212, making it impossible for the external light to pass through the linear polarization layer 212, and it can be absorbed by the linear polarization layer 212. Therefore, the polarizing plate 200 suppresses the re-reflection of external light incident on the display device 100 from the internal structure of the display device 100.

[0089] The linear polarization layer 212 may include a variety of dyes. The linear polarization layer 212 can be formed by mixing a reactive mesogen with the dye. The reactive mesogen may include liquid crystal polymers, liquid crystal molecules, or oligomers having mesogens, the mesogens having photosensitive groups exhibiting optical anisotropy and exhibiting liquid crystal properties at a specific temperature, or mixtures thereof. The reactive mesogen has a molecular structure similar to the dye, and the reactive mesogen is oriented at an angle along the alignment film 214, while the dye may be oriented in one direction along the reactive mesogen. The dye is dichroic and may include black dyes, or mixtures of red, green, and blue dyes, or mixtures of cyan, magenta, and yellow dyes.

[0090] An alignment film 214 is disposed on a linear polarization layer 212. The alignment film 214 aligns the dye in the linear polarization layer 212 in a specific direction. For example, a resin such as polyimide is subjected to a rubbing or other treatment to form an alignment film 214 with grooves in a specific direction.

[0091] Next, the black pattern BP includes a delay layer 211, a black layer 213, and a non-oriented film 215.

[0092] A retardation layer 211 is disposed on the second adhesive layer AD2. The retardation layer 211 of the black pattern BP is substantially the same as the retardation layer 211 of the polarization pattern PP. The retardation layer 211 may be composed of a portion overlapping the black layer 213 and another portion overlapping the linear polarization layer 212.

[0093] A black layer 213 is disposed on the delay layer 211. The black layer 213 absorbs light incident from the outside. The black layer 213 is configured to absorb natural light incident from the outside to suppress the reflection of external light in the stretchable region SA where the black layer 213 is located. The black layer 213 can improve the black brightness of the display device 100. Black brightness refers to the degree of blackness of the display device 100 in the off state, and the black layer 213 is formed to improve the black brightness.

[0094] The black layer 213 can be formed on the same layer as the linearly polarized layer 212 using the same material, and for example, it can be formed from a mixture of reactive mesocrystalline material and dye. However, in the black layer 213, the dye is randomly oriented to absorb light from various directions.

[0095] A non-oriented film 215 is disposed on the black layer 213. The non-oriented film 215 can be formed on the same layer as the oriented film 214 using the same material. However, the non-oriented film 215 is not subjected to a separate rubbing treatment, so that the dye in the black layer 213 is not oriented in a specific direction, but can be randomly oriented.

[0096] In the following text, reference will be made to Figures 7A to 7F A method for manufacturing a display device 100 and a polarizing plate 200 according to exemplary embodiments of the present disclosure is described.

[0097] Figures 7A to 7F This is a process diagram used to explain a method for manufacturing a display device according to exemplary embodiments of the present disclosure.

[0098] refer to Figure 7A An alignment film 214 and a non-alignment film 215 are formed on an upper substrate 112. Specifically, the materials constituting the alignment film 214 and the non-alignment film 215 can be formed on one surface of the upper substrate 112. Furthermore, a mask is provided on a stretchable region SA, and a rubbing process is performed only on the remaining portion not blocked by the mask, i.e., on a rigid region RA, to form the alignment film 214 in the rigid region RA and the non-alignment film 215 in the stretchable region SA.

[0099] refer to Figure 7B A linearly polarized layer 212 and a black layer 213 are formed on an alignment film 214 and a non-aligned film 215, and a retardation layer 211 is formed on the linearly polarized layer 212 and the black layer 213. Specifically, a mixture of reactive mesomorphic material and dye is coated onto the alignment film 214 and the non-aligned film 215. In the mixture coated on the alignment film 214, the dye can be oriented in one direction through the alignment film 214, while in the mixture coated on the non-aligned film 215, the dye can be randomly oriented. Next, the mixture of reactive mesomorphic material and dye is cured to form the linearly polarized layer 212 and the black layer 213. After the formation of the linearly polarized layer 212 and the black layer 213 is completed, the retardation layer 211 can be formed on the linearly polarized layer 212 and the black layer 213.

[0100] refer to Figure 7C The tear line TL is formed in the polarizer 200. Specifically, the tear line TL can be formed by irradiating a laser in the boundary between the rigid region RA and the stretchable region SA or in the stretchable region SA adjacent to the periphery of the rigid region RA.

[0101] At this point, the tear line TL passes through the polarizer 200 to reach the upper substrate 112. The depth of the tear line TL is greater than the thickness of the polarizer 200 and less than the sum of the thicknesses of the polarizer 200 and the upper substrate 112. When the tear line TL is formed, the intensity of the laser can be controlled so that the upper substrate 112 is not completely cut, but only a minimum portion of the upper substrate 112 is cut.

[0102] Furthermore, the laser used to form the tear line TL irradiates from the retardation layer 211 toward the upper substrate 112, causing the tear line TL to extend from the retardation layer 211 (or polarizer 200) to one surface of the upper substrate 112, and the tear line has a width that narrows from the retardation layer 211 (or polarizer 200) toward the upper substrate 112. Specifically, the width of the tear line TL is largest in the retardation layer 211, and the width of the tear line TL gradually decreases toward the upper substrate 112. The tear line TL has a V-shaped cross-sectional shape that narrows from the retardation layer 211 toward the upper substrate 112. However, even though the tear line TL has a V-shaped cross-section in the figures, the tear line may have a U-shaped cross-section or an I-shaped cross-section depending on the type of laser. It is not limited to this.

[0103] refer to Figure 7D A second adhesive layer AD2 is formed on the polarizer 200. The second adhesive layer AD2 can be formed on the delay layer 211 of the polarizer 200, and the second adhesive layer AD2 can fill the tear line TL.

[0104] refer to Figure 7E A patterned layer 120, on which multiple light-emitting diodes 170 and connecting lines 180 are formed, is bonded to an upper substrate 112, a polarizing plate 200, and a second adhesive layer AD2.

[0105] The pattern layer 120 on the temporary substrate SUB and the second adhesive layer AD2 on the upper substrate 112 are positioned opposite each other to bond the temporary substrate SUB and the upper substrate 112. Therefore, the temporary substrate SUB, on which the pattern layer 120, the light-emitting diode 170 and the connecting line 180 are formed, and the upper substrate 112, on which the polarizer 200 is formed, can be bonded by the second adhesive layer AD2.

[0106] The temporary substrate SUB is a component that supports the pattern layer 120 and the parts disposed on the pattern layer 120 during the manufacturing process of the display device 100. The temporary substrate SUB can be formed of a rigid material. For example, the temporary substrate SUB can be formed of glass, but is not limited thereto.

[0107] like Figure 7E As shown, the sacrificial layer SL is formed to easily separate the temporary substrate SUB from the patterning layer 120. A laser irradiates the sacrificial layer SL from below the temporary substrate SUB to dehydrogenate the sacrificial layer SL, thus separating the temporary substrate SUB and the sacrificial layer SL from the patterning layer 120. For example, the sacrificial layer SL can be hydrogenated amorphous silicon or hydrogenated amorphous silicon doped with impurities.

[0108] A sacrificial layer SL is formed on a temporary substrate SUB, and a pattern layer 120 and a plurality of pixels PX are formed on the sacrificial layer SL. The pattern layer 120 is formed on the sacrificial layer SL, and a plurality of circuits, a plurality of wirings, and a plurality of interconnects 180 can be formed on the pattern layer 120. In addition, a plurality of light-emitting diodes 170 are transferred onto a plurality of first board patterns 121 of the pattern layer 120 to form a plurality of sub-pixels SPX.

[0109] Finally, refer to Figure 7F The temporary substrate SUB is removed and the lower substrate 111 is bonded. A laser irradiates the sacrificial layer SL from the outside of the temporary substrate SUB to separate the temporary substrate SUB and the pattern layer 120. Furthermore, the lower substrate 111 can be bonded to one surface of the pattern layer 120 using a first adhesive layer AD1.

[0110] Therefore, in the manufacturing method of the display device 100 and polarizer 200 according to the exemplary embodiments of the present disclosure, the polarizer 200 is formed on one surface of the upper substrate 112, and the upper substrate 112 and the polarizer 200 are bonded to the lower substrate 111. By doing so, a display device 100 including the polarizer 200 can be formed. For example, the display device 100 can be formed by a roll-to-roll method, in which an alignment film 214, a linear polarization layer 212, and a retardation layer 211 are directly formed on the upper substrate 112, and the upper substrate 112 with the polarizer 200 attached is bonded to the lower substrate 111. Therefore, the manufacturing method of the display device 100 and polarizer 200 according to the exemplary embodiments of the present disclosure is advantageous for producing a large number of display devices 100. Furthermore, according to this manufacturing method, the adhesive layer for bonding the polarizer 200 and the upper substrate 112 is omitted, thereby saving manufacturing costs.

[0111] In the display device 100 according to an exemplary embodiment of the present disclosure, the polarizing plate 200 includes a polarizing pattern PP and a black pattern BP to improve black brightness while reducing external light reflection. In the unstretched rigid region RA, a polarizing pattern PP is formed in which dye is oriented in one direction to suppress external light reflection, and an image is displayed through a plurality of sub-pixels SPX. Furthermore, in the stretched stretchable region SA, a black layer 213 is provided to absorb external light. At this time, even if the black layer 213, in which dye is randomly disposed, is stretched, the black layer 213 can absorb light and achieve black in the stretchable region SA in which no sub-pixels SPX are provided, thereby improving the black brightness of the display device 100. Conversely, a polarizing pattern PP in which dye is oriented in a predetermined direction is provided in the unstretched rigid region RA to suppress deformation. Therefore, considering the characteristics of the rigid region RA and the stretchable region SA, the polarizing pattern PP is provided in the rigid region RA, and the black layer 213 is provided in the stretchable region SA to minimize external light reflection and improve black brightness.

[0112] In the display device 100 according to an exemplary embodiment of the present disclosure, a tear line TL is formed to separate the polarizing pattern PP from the black pattern BP, so as to minimize the deformation of the polarizing pattern PP. The black pattern BP is disposed in the stretchable region SA so as to stretch together when the display device 100 is stretched. In the polarizing plate 200, a tear line TL is formed to separate the black pattern BP in the stretchable region SA and the polarizing pattern PP in the rigid region RA, so that the polarizing pattern PP is not affected by the stretching of the black pattern BP. Therefore, a tear line TL is formed between the polarizing pattern PP and the black pattern BP to minimize the deformation of the polarizing pattern PP by the black pattern BP.

[0113] Figure 8 This is a schematic cross-sectional view of a display device according to another exemplary embodiment of the present disclosure. Figures 1 to 6 Compared to the display device 100, Figure 8 The display device 1000 further includes a third adhesive layer AD3, and the tear line TL' is different, but the other configurations are basically the same, so a redundant description will be omitted.

[0114] refer to Figure 8 The third adhesive layer AD3 can be disposed between the polarizer 200 and the upper substrate 112. By forming the polarizer 200 on a separate temporary substrate SUB and then bonding them to the second adhesive layer AD2, the third adhesive layer AD3 can be further disposed to bond the polarizer 200 and the upper substrate 112, thereby forming the display device 1000.

[0115] The cross-sectional shape of the tear line TL' can narrow from the linear polarization layer 212 toward the retardation layer 211. Figure 6 Similar to the tear line TL, the width of the tear line TL' on one surface of the polarizing plate 200 is different from the width of the tear line TL' on the opposite surface of the polarizing plate 200. Furthermore, the depth of the tear line TL' can be greater than the thickness of the polarizing plate 200. Therefore, the tear line TL' can be formed to reach the second adhesive layer AD2.

[0116] Furthermore, a third adhesive layer AD3 is configured to fill the tear line TL'. The third adhesive layer AD3 can be configured to fill the tear line TL' to surround the upper and sides of the polarization pattern PP.

[0117] In the following, a method for manufacturing a display device 1000 and a polarizing plate 200 according to exemplary embodiments of the present disclosure will be described.

[0118] Figures 9A to 9F This is a process diagram used to explain a method for manufacturing a display device according to another exemplary embodiment of the present disclosure.

[0119] refer to Figure 9A An alignment film 214 and a non-alignment film 215 are formed on a first temporary substrate SUB1. A sacrificial layer SL is formed on the first temporary substrate SUB1, and materials for forming the alignment film 214 and the non-alignment film 215 can be formed on the sacrificial layer SL. Furthermore, a mask is provided in a stretchable region SA, and a friction process is performed only in the rigid region RA exposed from the mask to form the alignment film 214.

[0120] refer to Figure 9B A linear polarization layer 212 and a black layer 213 are formed on an alignment film 214 and a non-alignment film 215, and a retardation layer 211 is formed on the linear polarization layer 212 and the black layer 213. A mixture of dye and reactive mesomorphic material is coated onto the alignment film 214 and the non-alignment film 215 and cured to form the linear polarization layer 212 and the black layer 213. Furthermore, a material for forming the retardation layer 211 is coated onto the linear polarization layer 212, and either the black layer 213 or the retardation layer 211 can be attached thereto.

[0121] refer to Figure 9C and Figure 9D A second adhesive layer AD2 is formed on the delay layer 211 to bond the first temporary substrate SUB1 and the second temporary substrate SUB2. First, the second adhesive layer AD2 can be formed on the first temporary substrate SUB1 on which the polarizer 200 is formed. Furthermore, the second adhesive layer AD2 can be used to bond the first temporary substrate SUB1 on which the polarizer 200 is formed to the second temporary substrate SUB2 on which the pattern layer 120, connecting lines 180, and a plurality of light-emitting diodes 170 are formed.

[0122] Next, the first temporary substrate SUB1 is separated from the polarizing plate 200, and a tear line TL' is formed in the polarizing plate 200. Specifically, the first temporary substrate SUB1 is irradiated with a laser to separate it from the polarizing plate 200. Furthermore, the laser irradiates the polarizing plate 200 exposed from the first temporary substrate SUB1 to form the tear line TL'.

[0123] The depth of the tear line TL' can be greater than the thickness of the polarizer 200. Therefore, the tear line TL' can be formed to reach the portion of the second adhesive layer AD2 that contacts the polarizer 200.

[0124] Furthermore, when forming the tear line TL', the laser irradiates one surface of the non-aligned film 215 and the aligned film 214, causing the tear line TL' to extend from the polarizer 200 to one surface of the second adhesive layer AD2, and the tear line TL' has a width that narrows from the polarizer 200 toward the second adhesive layer AD2. Specifically, the tear line TL' may have a width that narrows from the non-aligned film 215 toward the retardation layer 211.

[0125] refer to Figure 9E The upper substrate 112 is bonded to the polarizing plate 200 using a third adhesive layer AD3. The third adhesive layer AD3 can be formed on the polarizing plate 200. The third adhesive layer AD3 can be configured to fill the tear line TL' while covering one surface of the polarizing plate 200. Furthermore, the upper substrate 112 can be attached to the third adhesive layer AD3.

[0126] Finally, refer to Figure 9F The second temporary substrate SUB2 is removed, and the lower substrate 111 is bonded to the pattern layer 120 using the first adhesive layer AD1. A laser is applied to the second temporary substrate SUB2 to separate it from the pattern layer 120. Alternatively, the lower substrate 111 can be bonded below the pattern layer 120 using the first adhesive layer AD1.

[0127] Therefore, in the manufacturing method of the display device 1000 and polarizing plate 200 according to another exemplary embodiment of the present disclosure, after the polarizing plate 200 is formed on the first temporary substrate SUB1, the polarizing plate 200 is bonded to the lower substrate 111 and the upper substrate 112 to form the display device 1000. For example, the first temporary substrate SUB1 on which the polarizing plate 200 is formed is bonded to a second temporary substrate SUB2 on which a pattern layer 120 and a plurality of pixels PX are formed. Thereafter, the display device 1000 including the polarizing plate 200 is formed by separating the first temporary substrate SUB1 and the second temporary substrate SUB2 and attaching the lower substrate 111 and the upper substrate 112 in a unit-to-unit manner. At this time, with the polarizing plate 200 bonded to the pattern layer 120, a tear line TL' is formed, thereby allowing for more precise control of the formation area of ​​the tear line TL'. Furthermore, the first temporary substrate SUB1 and the second temporary substrate SUB2 are precisely aligned to minimize the alignment error between the polarizing plate 200 and the pattern layer 120. Therefore, in the manufacturing method of the display device 1000 and polarizing plate 200 according to another exemplary embodiment of the present disclosure, the position of the tear line TL' and the bonding position of the polarizing plate 200 and the pattern layer 120 are precisely adjusted. Thus, a high-resolution display device 1000 can be easily formed.
