[0028] In this specification, it should be understood that when an element (or region, layer, or portion, etc.) is referred to as being "on" another element, "connected to" or "coupled to" another element, the element may be directly disposed on / directly connected to / directly coupled to the other element, or an intermediate element may be disposed between them.

[0029] The same reference numerals or symbols always refer to the same elements. Furthermore, in the accompanying drawings, the thickness, scale, and dimensions of elements are exaggerated for the purpose of effectively describing the technical content.

[0030] The term “and / or” includes all combinations of one or more of the related listed elements.

[0031] Although the terms "first," "second," etc., can be used to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this invention, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. Unless the context clearly indicates otherwise, the singular form also includes the plural form.

[0032] Furthermore, terms such as “below,” “under,” “above,” and “above” may be used to describe the relationship between one element and another shown in the accompanying drawings. It will be understood that these terms are relative and are based on the directions shown in the accompanying drawings.

[0033] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Furthermore, unless expressly defined herein, terms (such as those defined in general dictionaries) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formalized sense.

[0034] It will be understood that, when used in this specification, the terms “comprising” or “including” indicate the presence of the stated features, integers, steps, operations, elements, components or combinations thereof, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0035] In the following description, embodiments of the present invention will be described with reference to the accompanying drawings.

[0036] Figure 1 This is a perspective view of the display device in its unfolded state according to an embodiment of the present invention.

[0037] Reference Figure 1 According to an embodiment of the present invention, the display device DD may have a quadrilateral shape in a planar view, the quadrilateral shape having a side extending in a first direction DR1 and a side extending in a second direction DR2 intersecting the first direction DR1. However, embodiments of the present invention are not limited thereto, and the display device DD may have various planar shapes, such as circles and polygons other than quadrilaterals. The display device DD may be a flexible display device.

[0038] In the following text, the direction substantially perpendicular to the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. Furthermore, in this specification, the term "when viewed in a plane (i.e., in a plan view)" can be defined as the state when viewed in the third direction DR3. The third direction DR3 is the thickness direction of the display device DD in its unfolded state.

[0039] The display device DD may include a foldable region FA and multiple non-foldable regions NFA1 and NFA2. The non-foldable regions NFA1 and NFA2 may include a first non-foldable region NFA1 and a second non-foldable region NFA2. The foldable region FA may be disposed between the first non-foldable region NFA1 and the second non-foldable region NFA2. In the unfolded state, the first non-foldable region NFA1, the foldable region FA, and the second non-foldable region NFA2 may be arranged in a first direction DR1.

[0040] An exemplary illustration shows a foldable region FA and two non-foldable regions NFA1 and NFA2, but the number of foldable regions FA and the number of non-foldable regions NFA1 and NFA2 are not limited thereto. In another example, the display device DD may include more than two non-foldable regions and multiple foldable regions, with the non-foldable regions disposed between the multiple foldable regions.

[0041] The upper surface of the display device DD can be defined as a display surface DS, and the display surface DS can be a flat surface defined by a first direction DR1 and a second direction DR2. The image IM generated by the display device DD can be provided to the user through the display surface DS.

[0042] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA. The display area DA may display an image, and the non-display area NDA may not display an image. The non-display area NDA may surround the display area DA and define the boundary of the display device DD printed in a predetermined color.

[0043] The display device DD may include at least one sensor SN and at least one camera CA. The sensor SN and camera CA may be adjacent to the boundary of the display device DD. The sensor SN and camera CA may be located in the display area DA adjacent to the non-display area NDA. The sensor SN and camera CA may be located in a second non-folding area NFA2, but are not limited thereto. In another embodiment, the sensor SN and camera CA may be located in a first non-folding area NFA1.

[0044] Light can pass through the portion of the display device DD in which the sensor SN and camera CA are located, and can be supplied to the camera CA and sensor SN. For example, the sensor SN can be a proximity sensor, but the type of sensor SN is not limited to this. The camera CA can capture external images. Multiple sensor SNs and multiple camera CAs can each be provided.

[0045] Figure 2 and Figure 3 It is shown Figure 1 The view shown is of the display device in a folded state.

[0046] Reference Figure 2 and Figure 3 The display device DD can be a foldable (foldable) display device DD that can be folded or unfolded. For example, the display device DD can be folded such that the foldable region FA bends relative to the folding axis FX parallel to the second direction DR2.

[0047] When the display device DD is folded, it can fold inwards, such that the first non-folded region NFA1 and the second non-folded region NFA2 face each other, and the display surface DS is not exposed to the outside. However, embodiments of the present invention are not limited to this. In another example, the display device DD can fold outwards relative to the folding axis FX, such that the display surface DS is exposed to the outside.

[0048] The foldable region FA can be bent to have a radius of curvature R1. For example... Figure 2 As shown, the distance between the first non-folded region NFA1 and the second non-folded region NFA2 can be substantially equal to twice the radius of curvature R1 (e.g., the diameter). In this case, the display device DD can be folded into a U-shape.

[0049] However, as Figure 3 As shown, the distance between the first non-folding region NFA1 and the second non-folding region NFA2 is not limited to this, and in another embodiment, the distance between the first non-folding region NFA1 and the second non-folding region NFA2 can be substantially less than twice the radius of curvature R1. In this case, the display device DD can be folded into a dumbbell-like shape.

[0050] Figure 4 A cross-sectional view of the electronic panel of a display device according to an embodiment of the present invention is shown as an example. Figure 5 Exemplary Figure 4 The diagram shows a cross-sectional view of the display panel.

[0051] For example, Figure 4 and Figure 5 The cross section is shown when viewed in the first direction DR1.

[0052] Reference Figure 4 The aforementioned display device DD (see Figure 1 ) can include Figure 4 The electronic panel EP shown herein may include a display panel DP, an input sensing unit ISP disposed on the display panel DP, and an anti-reflective layer RPL disposed on the input sensing unit ISP.

[0053] The display panel DP can be a flexible display panel. According to embodiments of the present invention, the display panel DP can be a light-emitting display panel. For example, the display panel DP can be an organic light-emitting display panel or an inorganic light-emitting display panel. The light-emitting layer of an organic light-emitting display panel can include organic light-emitting materials. The light-emitting layer of an inorganic light-emitting display panel can include quantum dots, quantum rods, etc. Hereinafter, the display panel DP is described as an organic light-emitting display panel.

[0054] The input sensing unit ISP may include multiple sensor units (not shown) for capacitively sensing external inputs. When the display device DD is manufactured, the input sensing unit ISP can be directly fabricated on the display panel DP. However, embodiments of the present invention are not limited thereto. In another embodiment, the input sensing unit ISP can be fabricated as a panel separate from the display panel DP and then attached to the display panel DP via an adhesive layer.

[0055] When the display device DD is manufactured, the anti-reflective layer RPL can be directly fabricated on the input sensing unit ISP. However, embodiments of the present invention are not limited thereto. In another embodiment, the anti-reflective layer RPL can be fabricated separately as a panel and then attached to the input sensing unit ISP via an adhesive layer.

[0056] The anti-reflective layer RPL can be defined as an external light anti-reflective film. The anti-reflective layer RPL can reduce the reflectivity of external light entering the display panel DP from above the display device DD.

[0057] Reference Figure 5 The display panel DP may include a substrate SUB, a circuit element layer DP-CL disposed on the substrate SUB, a display element layer DP-OLED disposed on the circuit element layer DP-CL, and a thin film encapsulation layer TFE disposed on the display element layer DP-OLED.

[0058] The substrate SUB may include a display area DA and a non-display area NDA surrounding the display area DA. The substrate SUB may include glass or a flexible plastic material such as polyimide (“PI”). The display element layer DP-OLED may be disposed within the display area DA.

[0059] Multiple pixels can be disposed in the circuit element layer DP-CL and the display element layer DP-OLED. Each pixel can include a transistor disposed in the circuit element layer DP-CL and a light-emitting element disposed in the display element layer DP-OLED and connected to the transistor.

[0060] A thin-film encapsulation layer (TFE) can be applied to the DP-CL circuit element layer to cover the DP-OLED display element layer. The TFE protects the pixels from moisture, oxygen, and external contaminants.

[0062] Reference Figure 6 The display device DD may include a display panel DP, a scan driver SDV, a data driver DDV, and a light-emitting driver EDV.

[0063] The display panel DP may include a first region AA1, a second region AA2, and a bent region BA between the first region AA1 and the second region AA2. The bent region BA may extend in the second direction DR2, and the first region AA1, the bent region BA, and the second region AA2 may be arranged in the first direction DR1 in the unfolded state.

[0064] The first region AA1 may include a display region DA and a non-display region NDA surrounding the display region DA. The non-display region NDA may surround the display region DA. The display region DA may display an image, and the non-display region NDA may not display an image. The second region AA2 and the curved region BA may not display an image.

[0065] When viewed in the second direction DR2, the first region AA1 may include a first non-foldable region NFA1, a second non-foldable region NFA2, and a foldable region FA between the first non-foldable region NFA1 and the second non-foldable region NFA2. The first non-foldable region NFA1, the second non-foldable region NFA2, and the foldable region FA may respectively correspond to Figure 1 The display device DD shown has a first non-foldable region NFA1, a second non-foldable region NFA2, and a foldable region FA.

[0066] The first region AA1 can be folded relative to the aforementioned folding axis FX (see...). Figure 2 and Figure 3 (bending.) For example, the display panel DP can be folded such that the foldable area FA of the first region AA1 is bent relative to the aforementioned folding axis FX.

[0067] The display panel DP may include multiple pixels PX, multiple scan lines SL1 to SLm, multiple data lines DL1 to DLn, multiple light-emitting lines EL1 to ELm, a first control line CSL1 and a second control line CSL2, a power line PL, multiple connection lines CNL, and multiple pads PD. m and n are natural numbers greater than 0. Pixels PX may be located in the display area DA and connected to scan lines SL1 to SLm, data lines DL1 to DLn, and light-emitting lines EL1 to ELm.

[0068] The scan driver (SDV) and the light-emitting driver (EDV) can be disposed in the non-display area (NDA). The scan driver (SDV) and the light-emitting driver (EDV) can be disposed in the non-display area (NDA) adjacent to each other on opposite sides of the first area (AA1) in the second direction (DR2). The data driver (DDV) can be disposed in the second area (AA2). The data driver (DDV) can be manufactured as an integrated circuit chip and mounted on the display panel (DP) in the second area (AA2).

[0069] Although not shown, the bending region BA can be bent, and the second region AA2 can be located below the first region AA1. Accordingly, when the bending region BA is bent, the data driver DDV is located below the first region AA1 and can therefore be invisible from the outside.

[0070] Scan lines SL1 to SLm can extend in the second direction DR2 to connect to the scan driver SDV. Data lines DL1 to DLn can extend in the first direction DR1 to connect to the data driver DDV via the bend area BA. The data driver DDV can connect to the pixel PX via data lines DL1 to DLn. Emitting lines EL1 to ELm can extend in the second direction DR2 to connect to the emitting driver EDV.

[0071] The power supply line PL can extend along the first direction DR1 and is located in the non-display area NDA. The power supply line PL can be located between the display area DA and the light-emitting driver EDV. The power supply line PL can extend to the second area AA2 via the bending area BA. When viewed in a plane (i.e., in a plan view), the power supply line PL can extend towards the lower end of the second area AA2. The power supply line PL can receive a drive voltage.

[0072] The connecting line CNL can extend along the second direction DR2 and be arranged along the first direction DR1. The connecting line CNL can be connected to the power line PL and the pixel PX. The driving voltage can be applied to the pixel PX via the power line PL and the connecting line CNL connected to each other.

[0073] The first control line CSL1 can be connected to the scan driver SDV and extends through the bend area BA towards the lower end of the second area AA2. The second control line CSL2 can be connected to the light-emitting driver EDV and extends through the bend area BA towards the lower end of the second area AA2. The data driver DDV can be located between the first control line CSL1 and the second control line CSL2.

[0074] When viewed in a plane (i.e., in a plan view), pad PD can be positioned adjacent to the lower end of the second region AA2. Data driver DDV, power line PL, first control line CSL1, and second control line CSL2 can be connected to pad PD.

[0075] Data lines DL1 to DLn can be connected to the corresponding pads PD via the data driver DDV. For example, data lines DL1 to DLn can be connected to the data driver DDV, and the data driver DDV can be connected to the pads PD corresponding to the data lines DL1 to DLn respectively.

[0076] Although not shown, a printed circuit board (PCB) can be connected to pads (PD), and a timing controller and voltage generator can be mounted on the PCB. The timing controller can be manufactured as an integrated circuit chip and mounted on the PCB. The timing controller and voltage generator can be connected to pads (PD) via the PCB.

[0077] The timing controller can control the operation of the scan driver (SDV), data driver (DDV), and light driver (EDV). The timing controller can generate scan control signals, data control signals, and light control signals in response to control signals received from an external source. The voltage generator can generate drive voltages to be applied to the pixel (PX).

[0078] The scan control signal can be provided to the scan driver SDV via the first control line CSL1. The light emission control signal can be provided to the light emission driver EDV via the second control line CSL2. The data control signal can be provided to the data driver DDV. The timing controller can receive image signals from the outside, convert the data format of the image signals to conform to the interface specification of the data driver DDV, and provide the converted signals to the data driver DDV.

[0079] The scan driver SDV can generate multiple scan signals in response to scan control signals. These scan signals can be applied to pixels PX via scan lines SL1 to SLm. The scan signals can be applied to pixels PX sequentially.

[0080] The data driver DDV can generate multiple data voltages corresponding to the image signal in response to a data control signal. These data voltages can be applied to pixel PX via data lines DL1 to DLn. The light-emitting driver EDV can generate multiple light-emitting signals in response to a light-emitting control signal. These light-emitting signals can be applied to pixel PX via light-emitting lines EL1 to ELm.

[0081] A pixel (PX) can receive a data voltage in response to a scan signal. A pixel (PX) can display an image by emitting light with a brightness corresponding to the data voltage in response to a light emission signal. The emission time of a pixel (PX) can be controlled by the light emission signal.

[0082] Figure 7 An example is shown corresponding to Figure 6 The image shows a cross-sectional view of an electronic panel containing one pixel.

[0083] Reference Figure 7 A pixel (PX) may include a transistor (TR) and a light-emitting element (OLED). The light-emitting element (OLED) may include a first electrode (AE) (or anode), a second electrode (CE) (or cathode), a hole control layer (HCL), an electron control layer (ECL), and a light-emitting layer (EML).

[0084] The transistor TR and the light-emitting element OLED can be disposed on the substrate SUB. An exemplary transistor TR is shown in the accompanying drawings; however, in practice, the pixel PX may include at least one capacitor and multiple transistors for driving the light-emitting element OLED.

[0085] The display area DA may include a light-emitting area PA corresponding to each of the plurality of pixels PX, and a non-light-emitting area NPA surrounding the light-emitting area PA. The light-emitting element OLED may be disposed in the light-emitting area PA.

[0086] The buffer layer (BFL) can be disposed on the substrate (SUB), and the buffer layer (BFL) can be an inorganic layer. A semiconductor pattern can be disposed on the buffer layer (BFL). The semiconductor pattern can include polycrystalline silicon, amorphous silicon, or metal oxide.

[0087] Semiconductor patterns can be doped with N-type or P-type dopants. Semiconductor patterns can include heavily doped and lightly doped regions. Heavily doped regions can have higher conductivity than lightly doped regions and essentially serve as the source and drain electrodes of a transistor TR. Lightly doped regions can essentially correspond to the active region (or channel region) of the transistor TR.

[0088] The source S (i.e., source electrode), active region A, and drain D (i.e., drain electrode) of transistor TR can be formed from a semiconductor pattern. A first insulating layer INS1 can be disposed on the semiconductor pattern. The gate G of transistor TR can be disposed on the first insulating layer INS1. A second insulating layer INS2 can be disposed on the gate G. A third insulating layer INS3 can be disposed on the second insulating layer INS2.

[0089] The connection electrode CNE may include a first connection electrode CNE1 and a second connection electrode CNE2 that connect the transistor TR to the light-emitting element OLED. The first connection electrode CNE1 may be disposed on the third insulating layer INS3 and connected to the drain electrode D via a first contact hole CH1 defined in the first insulating layer INS1 to the third insulating layer INS3.

[0090] A fourth insulating layer INS4 may be disposed on the first connecting electrode CNE1. A fifth insulating layer INS5 may be disposed on the fourth insulating layer INS4. A second connecting electrode CNE2 may be disposed on the fifth insulating layer INS5.

[0091] The sixth insulating layer INS6 can be disposed on the second connection electrode CNE2. The layer from the buffer layer BFL to the sixth insulating layer INS6 can be defined as the circuit element layer DP-CL. The first insulating layer INS1 to the sixth insulating layer INS6 can each be an inorganic layer or an organic layer.

[0092] A first electrode AE ​​can be disposed on a sixth insulating layer INS6. The first electrode AE ​​can be connected to a second connecting electrode CNE2 via a third contact hole CH3 defined in the sixth insulating layer INS6. A pixel defining film PDL can be disposed on the first electrode AE ​​and the sixth insulating layer INS6, and an opening PX_OP is defined in the pixel defining film PDL for exposing a predetermined portion of the first electrode AE.

[0093] The hole control layer (HCL) can be disposed on the first electrode (AE) and the pixel defining film (PDL). The hole control layer (HCL) may include a hole transport layer and a hole injection layer.

[0094] The luminescent layer (EML) can be disposed on the hole control layer (HCL). The EML can be disposed in the region corresponding to the opening (PX_OP). The EML can include organic and / or inorganic materials. The EML can generate light with one of the colors red, green, and blue.

[0095] The electron control layer (ECL) can be disposed on the light-emitting layer (EML) and the hole control layer (HCL). The ECL may include an electron transport layer and an electron injection layer. The hole control layer (HCL) and the ECL can be commonly disposed in the light-emitting region (PA) and the non-light-emitting region (NPA).

[0096] The second electrode CE can be disposed on the electronic control layer ECL. The second electrode CE can also be commonly disposed in the pixel PX. The layer where the light-emitting element OLED is disposed can be defined as the display element layer DP-OLED.

[0097] A thin-film encapsulation layer (TFE) can be disposed on the second electrode (CE) to cover the pixel (PX). The thin-film encapsulation layer (TFE) may include a first encapsulation layer (EN1) disposed on the second electrode (CE), a second encapsulation layer (EN2) disposed on the first encapsulation layer (EN1), and a third encapsulation layer (EN3) disposed on the second encapsulation layer (EN2).

[0098] The first encapsulation layer EN1 and the third encapsulation layer EN3 may include inorganic insulating layers and protect the pixel PX from moisture / oxygen. The second encapsulation layer EN2 may include organic insulating layers and protect the pixel PX from foreign matter such as dust particles.

[0099] A first voltage can be applied to the first electrode AE ​​via transistor TR, and a second voltage having a lower level than the first voltage can be applied to the second electrode CE. Holes and electrons injected into the light-emitting layer EML recombine to form excitons, and the excitons transition to the ground state, enabling the light-emitting element OLED to emit light.

[0100] The layer from the substrate (SUB) to the thin-film encapsulation layer (TFE) can be defined as the display panel (DP). The input sensing unit (ISP) can be disposed on the thin-film encapsulation layer (TFE). The input sensing unit (ISP) can be directly fabricated on the upper surface of the thin-film encapsulation layer (TFE).

[0101] The substrate layer BS can be disposed on the thin-film encapsulation layer TFE. The substrate layer BS may include an inorganic insulating layer. At least one inorganic insulating layer may be provided as the substrate layer BS on the thin-film encapsulation layer TFE.

[0102] The input sensing unit (ISP) may include a first conductive pattern CTL1 and a second conductive pattern CTL2 disposed on the first conductive pattern CTL1. The first conductive pattern CTL1 may be disposed on a substrate layer BS. An insulating layer TINS ​​may be disposed on the substrate layer BS to cover the first conductive pattern CTL1. The insulating layer TINS ​​may include an inorganic insulating layer or an organic insulating layer. The second conductive pattern CTL2 may be disposed on the insulating layer TINS.

[0103] The first conductive pattern CTL1 and the second conductive pattern CTL2 may overlap with the non-light-emitting region NPA. Although not shown, the first conductive pattern CTL1 and the second conductive pattern CTL2 may be disposed in the non-light-emitting region NPA between the light-emitting regions PA and have a grid shape.

[0104] The first conductive pattern CTL1 and the second conductive pattern CTL2 can form the sensor of the aforementioned input sensing unit ISP. For example, the first conductive pattern CTL1 and the second conductive pattern CTL2, which have a grid shape, can be separated from each other in a predetermined area and form the sensor. A portion of the second conductive pattern CTL2 can be connected to the first conductive pattern CTL1.

[0105] An anti-reflective layer RPL can be disposed on a second conductive pattern CTL2. The anti-reflective layer RPL may include a black matrix BM and multiple color filters CF. The black matrix BM may overlap with the non-emitting region NPA, and the color filters CF may overlap with the emitting region PA.

[0106] A black matrix BM can be disposed on the insulating layer TINS ​​to cover the second conductive pattern CTL2. The light-emitting region PA and the opening B_OP overlapping with the opening PX_OP can be confined within the black matrix BM. The black matrix BM can absorb and block light. The width of the opening B_OP can be greater than the width of the opening PX_OP.

[0107] Color filters (CF) can be placed on the insulating layer (TINS) and the black matrix (BM). Color filters (CF) can also be placed in the opening (B_OP). Planarized insulating layer (PINS) can be placed on the color filters (CF). Planarized insulating layer (PINS) provides a flat top surface.

[0108] When external light propagating towards the display panel DP is reflected at the display panel DP and then re-provided to an external user, the external light may be observed by the user as if it were reflected from a mirror. To prevent this phenomenon, for example, the anti-reflective layer RPL may include a color filter CF that displays the same color as the pixels PX of the display panel DP. The color filter CF can filter out external light that has the same color as the pixels PX. In this case, the external light is invisible to the user.

[0109] However, embodiments of this invention are not limited thereto, and in another embodiment, the antireflective layer RPL may include a polarizing film for reducing the reflectivity of external light. The polarizing film may be manufactured separately and attached to the input sensing unit ISP via an adhesive layer. The polarizing film may include a phase delayer and / or a polarizer.

[0110] Figure 8 It corresponds to along Figure 6The cross-sectional view of the display module is shown by the section cut by line I-I'.

[0111] Reference Figure 8 The aforementioned display device DD (see Figure 1 ) can include Figure 8 The display module DM shown here may include a hard coating layer HC, a printed layer PIT, a window WIN, a window protective layer WP, an impact absorbing layer ISL, an electronic panel EP, a panel protective layer PPL, a support plate PLT, and first adhesive layers AL1 to fifth adhesive layers AL5.

[0112] The display module DM can be a flexible display module. The display module DM may include a first non-foldable region NFA1, a foldable region FA, and a second non-foldable region NFA2. The display module DM can be folded such that the foldable region FA is relative to the aforementioned folding axis FX (see above). Figure 2 and Figure 3 () was folded.

[0113] The window (WIN) can be disposed on the shock-absorbing layer (ISL). The window (WIN) can protect the electronic panel (EP) from external scratches. The window (WIN) can have optically transparent properties. The window (WIN) can include glass. However, embodiments of the present invention are not limited thereto, and in another embodiment, the window (WIN) can include a synthetic resin film.

[0114] A window WIN can have a single-layer or multi-layer structure. For example, a window WIN may include multiple synthetic resin films bonded together with an adhesive, or a window WIN may include a glass substrate and synthetic resin films bonded together with an adhesive.

[0115] A window protective layer WP can be applied to the window WIN. The window protective layer WP may include flexible plastic materials, such as polyimide or polyethylene terephthalate. A hard coating HC can be applied to the upper surface of the window protective layer WP.

[0116] The printed layer PIT can be disposed on the lower surface of the window protective layer WP. The printed layer PIT can be black, but the color of the printed layer PIT is not limited to this. In another embodiment, the printed layer PIT can be adjacent to the boundary of the window protective layer WP.

[0117] An impact-absorbing layer (ISL) can be applied to the electronic panel EP. The ISL absorbs external impacts applied to the electronic panel EP from above the display device DD, thus protecting the electronic panel EP. The ISL can be manufactured in the form of a stretched film.

[0118] The impact-absorbing layer (ISL) may include a flexible plastic material. The flexible plastic material may be defined as a synthetic resin film. For example, the impact-absorbing layer (ISL) may include a flexible plastic material such as polyimide (“PI”) or polyethylene terephthalate (“PET”).

[0119] The panel protective layer PPL can be disposed below the electronic panel EP. The panel protective layer PPL can be disposed below the display panel DP. The panel protective layer PPL protects the lower part of the display panel DP. The panel protective layer PPL can include a flexible plastic material. For example, the panel protective layer PPL can include polyethylene terephthalate (“PET”).

[0120] A support plate (PLT) can be disposed beneath the panel protective layer (PPL) and support the electronic panel (EP). The support plate (PLT) can include non-metallic materials. For example, the support plate (PLT) can include a fiber-reinforced composite material. The fiber-reinforced composite material can be carbon fiber reinforced plastic (“CFRP”) or glass fiber reinforced plastic (“GFRP”).

[0121] The support plate PLT comprises a reinforcing fiber composite material, and therefore can have a light weight. According to an embodiment, the support plate PLT comprises a reinforcing fiber composite material, and therefore can not only have a lighter weight than a metal support plate made of metallic material, but also have a modulus and strength similar to that of a metal support plate.

[0122] The support plate PLT comprises reinforcing fiber composite material, and therefore its shape processing can be performed more easily compared to that of a metal support plate. For example, the support plate PLT comprising reinforcing fiber composite material can be processed more easily by laser technology or micro-blasting technology.

[0123] Multiple openings (OPs) can be defined in the portion of the support plate PLT that overlaps with the foldable region FA. The openings (OPs) can be formed as portions extending through the support plate PLT in the third direction DR3. The openings (OPs) can be formed using the aforementioned laser processing or micro-blasting process.

[0124] The first adhesive layer AL1 can be disposed between the window protective layer WP and the window WIN. The window protective layer WP and the window WIN can be bonded to each other via the first adhesive layer AL1. The first adhesive layer AL1 can cover the printed layer PIT.

[0125] The second adhesive layer AL2 can be disposed between the window WIN and the shock-absorbing layer ISL. The window WIN and the shock-absorbing layer ISL can be bonded to each other via the second adhesive layer AL2.

[0126] The third adhesive layer AL3 can be disposed between the shock-absorbing layer ISL and the electronic panel EP. The shock-absorbing layer ISL and the electronic panel EP can be bonded to each other via the third adhesive layer AL3.

[0127] A fourth adhesive layer AL4 can be disposed between the electronic panel EP and the panel protective layer PPL. The electronic panel EP and the panel protective layer PPL can be bonded to each other via the fourth adhesive layer AL4.

[0128] The fifth adhesive layer AL5 can be disposed between the panel protective layer PPL and the support plate PLT. The panel protective layer PPL and the support plate PLT can be bonded to each other via the fifth adhesive layer AL5.

[0129] The first adhesive layer AL1 to the fifth adhesive layer AL5 may include transparent adhesives, such as pressure-sensitive adhesives (“PSA”) or optically transparent adhesives (“OCA”), but the type of adhesive is not limited to these.

[0130] Figure 9 It is in the unfolded state. Figure 8 A perspective view of the support plate shown. Figure 10 yes Figure 9 An enlarged view of the first region A1 shown.

[0131] Reference Figure 9 and Figure 10 The support plate PLT may include a first non-foldable portion NFP1, a foldable portion FP, and a second non-foldable portion NFP2. The foldable portion FP may be disposed between the first non-foldable portion NFP1 and the second non-foldable portion NFP2. When viewed in a plane (i.e., in a plan view), the first non-foldable portion NFP1 may overlap with the first non-foldable region NFA1, the foldable portion FP may overlap with the foldable region FA, and the second non-foldable portion NFP2 may overlap with the second non-foldable region NFA2.

[0132] Multiple openings (OPs) can be confined within the folded portion (FP) to form a grid pattern. The openings (OPs) can be arranged according to a predetermined rule. Because the openings (OPs) are confined within the folded portion (FP), the area of ​​the folded portion (FP) is reduced, and therefore the folded portion (FP) can have reduced stiffness. When the openings (OPs) are confined within the folded portion (FP), the flexibility of the folded portion (FP) can be enhanced compared to when the openings (OPs) are not confined within it. Accordingly, the folded portion (FP) can be bent more easily.

[0133] Reference Figure 10An opening OP can be arranged in a first direction DR1 and a second direction DR2. The opening OP in the second direction DR2 can extend longer than it does in the first direction DR1. For example, an opening OP arranged in column h and an opening OP arranged in column (h+1) can be set to be offset from each other. h is a natural number greater than 0, and the column direction can correspond to the second direction DR2.

[0134] Figure 11 yes Figure 1 An exploded perspective view of the display device shown.

[0135] Reference Figure 11 The display device DD may include a display module DM and a folding component FST disposed below the display module DM. The folding component FST can support the display module DM below the display module DM and allow the display module DM to be folded.

[0136] The folding assembly FST may include a first support member SUP1, a second support member SUP2, multiple hinges HIG1 and HIG2, a central frame CFM, and a cover member CVP. The first support member SUP1 and the second support member SUP2 may be spaced apart from each other in a first direction DR1. The first direction DR1 may be defined as a horizontal direction.

[0137] When viewed in a plane (i.e., in a plan view), the first support member SUP1 can be positioned below and overlap with the first non-folded region NFA1. The first support member SUP1 can support the first non-folded region NFA1 below it.

[0138] The second support member SUP2 can be disposed below the second non-folded region NFA2, and when viewed in a plane (i.e., in a plan view), it can overlap with the second non-folded region NFA2. The second support member SUP2 can support the second non-folded region NFA2 below it.

[0139] Hinges HIG1 and HIG2, along with the center frame CFM, can be positioned below the foldable area FA. Hinges HIG1 and HIG2, along with the center frame CFM, can be positioned between the first support member SUP1 and the second support member SUP2. Hinges HIG1 and HIG2, along with the center frame CFM, can be arranged in the second direction DR2. Hinges HIG1 and HIG2 can be separated from each other in the second direction DR2.

[0140] HIG1 and HIG2 may include a first hinge HIG1 and a second hinge HIG2. The first hinge HIG1 and the second hinge HIG2 may be spaced apart from each other in a second direction DR2. The center frame CFM may be disposed between the first hinge HIG1 and the second hinge HIG2.

[0141] The first hinge HIG1 and the second hinge HIG2 can define dual-axis rotation axes RX1 and RX2 that are parallel to each other and extend in the second direction DR2. The dual-axis rotation axes RX1 and RX2 can substantially correspond to the aforementioned folding axis FX (see...). Figure 2 The dual-axis rotation axes RX1 and RX2 may include a first rotation axis RX1 adjacent to the first support member SUP1 and a second rotation axis RX2 adjacent to the second support member SUP2.

[0142] The first hinge HIG1 and the second hinge HIG2 may be adjacent to the opposite sides of the first support member SUP1 and the second support member SUP2 in the second direction DR2. The first hinge HIG1 and the second hinge HIG2 may be coupled to the first support member SUP1 and the second support member SUP2. The center frame CFM may be coupled to the first hinge HIG1 and the second hinge HIG2.

[0143] The first hinge HIG1 and the second hinge HIG2 allow the first support member SUP1 and the second support member SUP2 to rotate relative to the dual-axis rotation axes RX1 and RX2. The first hinge HIG1 and the second hinge HIG2 allow the first support member SUP1 to rotate relative to the first axis of rotation RX1. The first hinge HIG1 and the second hinge HIG2 allow the second support member SUP2 to rotate relative to the second axis of rotation RX2.

[0144] When the first hinge HIG1 and the second hinge HIG2 cause the first support member SUP1 and the second support member SUP2 to rotate relative to the dual-axis rotation axes RX1 and RX2, the display module DM can be folded through the first support member SUP1 and the second support member SUP2.

[0145] Although not shown, the display module DM can be attached to the first support member SUP1 and the second support member SUP2 via an adhesive layer.

[0146] The cover component CVP can be located below the first hinge HIG1, the second hinge HIG2, and the center frame CFM. The cover component CVP can be connected to the first hinge HIG1, the second hinge HIG2, and the center frame CFM.

[0147] Figure 12 yes Figure 11 The exploded perspective view of the folded component shown.

[0148] Reference Figure 12 The first hinge HIG1 and the second hinge HIG2 may have shapes that are symmetrical to each other with respect to a plane (i.e., a plane defined by a first direction DR1 and a third direction DR3), which is between the first hinge HIG1 and the second hinge HIG2 and is parallel to the first direction DR1 and perpendicular to the second direction DR2. The first hinge HIG1 may have a configuration that is substantially the same as that of the second hinge HIG2.

[0149] The first hinge HIG1 may include a first body BD1 and a plurality of first rotating parts ROP1. The first body BD1 may extend in the second direction DR2 and is disposed between the first support part SUP1 and the second support part SUP2.

[0150] The first rotating component ROP1 may extend in the first direction DR1 and be rotatably coupled to the first body BD1. Each of the first rotating components ROP1 may be rotatably coupled to an opposite side of the first body BD1 in the first direction DR1. The first rotating component ROP1 may be adjacent to the opposite side of the first body BD1 that faces the central frame CFM in the first direction DR1.

[0151] The first recessed portion RES1 can be defined in the upper surfaces of the first support member SUP1 and the second support member SUP2 adjacent to the first rotating member ROP1. The first rotating member ROP1 can each be disposed in the first recessed portion RES1.

[0152] The first hinge HIG1 may include a plurality of first coupling pins PN1 extending in a first direction DR1 from the first rotating member ROP1 toward the first support member SUP1 and the second support member SUP2. The upper surface of the first body BD1 adjacent to one side of the first body BD1 may be recessed downward.

[0153] The second hinge HIG2 may include a second body BD2 and a plurality of second rotating parts ROP2. The second body BD2 may extend in the second direction DR2 and is disposed between the first support part SUP1 and the second support part SUP2.

[0154] The second rotating component ROP2 may extend along the first direction DR1 and be rotatably coupled to the second body BD2. Each of the second rotating components ROP2 may be rotatably coupled to an opposite side of the second body BD2 along the first direction DR1. The second rotating component ROP2 may be adjacent to the opposite side of the second body BD2 along the first direction DR1 that faces the central frame CFM.

[0155] The second recessed portion RES2 can be defined in the upper surfaces of the first support member SUP1 and the second support member SUP2 adjacent to the second rotating member ROP2. The second rotating member ROP2 can each be disposed in the second recessed portion RES2.

[0156] The second hinge HIG2 may include a plurality of second coupling pins PN2 extending in the first direction DR1 from the second rotating member ROP2 toward the first support member SUP1 and the second support member SUP2. The upper surface of the second body BD2 adjacent to one side of the second body BD2 may be recessed downward.

[0157] The lower surface of the central frame CFM adjacent to the first body BD1 can be concave upwards. Furthermore, the lower surface of the central frame CFM adjacent to the second body BD2 can be concave upwards.

[0158] The cover component CVP may include multiple hinge covers CV1 and CV2 and a center cover CCV. Hinge covers CV1 and CV2 may be disposed below hinges HIG1 and HIG2, and the center cover CCV may be disposed below the center frame CFM. Hinge covers CV1 and CV2 may be in a separated state. Hinge covers CV1 and CV2 may be disposed below hinges HIG1 and HIG2 respectively to correspond one-to-one with (e.g., cover) hinges HIG1 and HIG2.

[0159] Hinge covers CV1 and CV2 may include a first hinge cover CV1 disposed below a first hinge HIG1 and a second hinge cover CV2 disposed below a second hinge HIG2. The first hinge cover CV1 and the second hinge cover CV2 may be separable from each other and spaced apart in a second direction DR2. A center cover CCV may be disposed between the first hinge cover CV1 and the second hinge cover CV2.

[0160] The cover component CVP may include a plurality of first coupling pins CP1 extending upward from the upper surface of the first hinge cover CV1 and a plurality of second coupling pins CP2 extending upward from the upper surface of the second hinge cover CV2. Furthermore, the cover component CVP may include a plurality of coupling pins CP extending upward from the upper surface of the center cover CCV.

[0161] The first fastening hole CH1' can be defined in the portion of the first support member SUP1 and the second support member SUP2 each having a first recessed portion RES1 therein. The second fastening hole CH2' can be defined in the portion of the first support member SUP1 and the second support member SUP2 each having a second recessed portion RES2 therein.

[0162] Figure 13A and Figure 13B It is along Figure 12 The cross-sectional view taken by line II-II' shown.

[0163] For example, Figure 13A The diagram shows the state in which the first support member SUP1 and the second support member SUP2 are coupled to the first hinge HIG1, and... Figure 13B The diagram shows the state in which the first support component SUP1 and the second support component SUP2 are separated from the first hinge HIG1.

[0164] Reference Figure 12 and Figure 13A The first hinge HIG1 can be coupled to the first support member SUP1 and the second support member SUP2. For example, the first rotating member ROP1 can be disposed in the first recessed portion RES1 to be coupled to the first support member SUP1 and the second support member SUP2.

[0165] The first rotating component ROP1 can be coupled to the first supporting component SUP1 and the second supporting component SUP2 via multiple fastening units CU. For example, the fastening unit CU can be a screw. In the unfolded state, the fastening groove CGV, which overlaps with the first fastening hole CH1' in the plan view, can be defined in the lower surface of the first rotating component ROP1. The fastening units CU are embedded in the first fastening hole CH1' and the fastening groove CGV, so that the first rotating component ROP1 can be coupled to the first supporting component SUP1 and the second supporting component SUP2.

[0166] Although not shown, the coupling structure between the second hinge HIG2 and the first support member SUP1 and the second support member SUP2 can be the same as or similar to the coupling structure between the first hinge HIG1 and the first support member SUP1 and the second support member SUP2. For example, the second rotating member ROP2 can be disposed in the second recessed portion RES2. Next, the fastening unit CU is embedded in the second fastening hole CH2' and the fastening groove CGV such that the second hinge HIG2 can be coupled to the first support member SUP1 and the second support member SUP2. In the unfolded state, in the plan view, the fastening groove CGV is defined in the lower surface of the second rotating member ROP2 to overlap with the second fastening hole CH2'.

[0167] Reference Figure 13A and Figure 13B When the fastening unit CU is separated from the first rotating component ROP1, the first supporting component SUP1, and the second supporting component SUP2, the first rotating component ROP1, the first supporting component SUP1, and the second supporting component SUP2 can be separated from each other.

[0168] Although not shown, the second rotating component ROP2, the first support component SUP1, and the second support component SUP2 can be separated from each other when the fastening unit CU is separated from the second rotating component ROP2, the first support component SUP1, and the second support component SUP2.

[0169] Therefore, the first rotating component ROP1 and the second rotating component ROP2 can be detachably coupled to the first support component SUP1 and the second support component SUP2 via the fastening unit CU. That is, the first hinge HIG1 and the second hinge HIG2 can each be detachably coupled to the first support component SUP1 and the second support component SUP2.

[0170] Figure 14A and Figure 14B It is along Figure 12 The cross-sectional view taken by line III-III' shown.

[0171] For example, Figure 14A The diagram shows the state in which the first support member SUP1 and the second support member SUP2 are coupled to the first hinge HIG1, and... Figure 14B The diagram shows the state in which the first support component SUP1 and the second support component SUP2 are separated from the first hinge HIG1.

[0172] Reference Figure 12 and Figure 14A The first rotating component ROP1 can be coupled to the first support component SUP1 and the second support component SUP2 via a first coupling pin PN1. For example, a fastening groove CGV-1 overlapping with the first coupling pin PN1 can be defined in the inner surface of the first support component SUP1 and the second support component SUP2, having a first recessed portion RES1 defined therein. The first coupling pin PN1 is embedded in the fastening groove CGV-1, such that the first rotating component ROP1 can be coupled to the first support component SUP1 and the second support component SUP2.

[0173] Due to external force, the first coupling pin PN1 can be embedded into the fastening groove CGV-1. When the diameter of the first coupling pin PN1 is smaller than the diameter of the fastening groove CGV-1, the first coupling pin PN1 may be easily separated from the first support member SUP1 and the second support member SUP2. Therefore, the diameter of the first coupling pin PN1 can be the same as or slightly larger than the diameter of the fastening groove CGV-1.

[0174] The first hinge HIG1, the first support member SUP1, and the second support member SUP2 can be formed of plastic material. In this case, when a predetermined external force is applied to the first coupling pin PN1, the first coupling pin PN1 can be forcibly tightened and fixed to the first support member SUP1 and the second support member SUP2.

[0175] Although not shown, the coupling structure between the second hinge HIG2 and the first support member SUP1 and the second support member SUP2 can be the same as or similar to the coupling structure between the first hinge HIG1 and the first support member SUP1 and the second support member SUP2. For example, the second coupling pin PN2 of the second hinge HIG2 is embedded in the fastening groove CGV-1 so that the second hinge HIG2 and the first support member SUP1 and the second support member SUP2 can be coupled to each other, and the fastening groove CGV-1 is defined in the first support member SUP1 and the second support member SUP2 to overlap with the second coupling pin PN2.

[0176] Reference Figure 14A and Figure 14B When the first coupling pin PN1 separates from the first support member SUP1 and the second support member SUP2 due to a predetermined external force, the first rotating member ROP1 and the first support member SUP1 and the second support member SUP2 can be separated from each other.

[0177] Although not shown, the second rotating component ROP2 and the first and second supporting components SUP1 and SUP2 can be separated from each other when the second coupling pin PN2 is separated from the first supporting component SUP1 and the second supporting component SUP2 due to a predetermined external force.

[0178] Therefore, the first rotating component ROP1 and the second rotating component ROP2 can be detachably coupled to the first support component SUP1 and the second support component SUP2 via the first coupling pin PN1 and the second coupling pin PN2. That is, the first hinge HIG1 and the second hinge HIG2 can each be detachably coupled to the first support component SUP1 and the second support component SUP2.

[0179] Figure 15A , Figure 15B and Figure 15C It is along Figure 12 The cross-sectional view shown is taken from line IV-IV'.

[0180] For example, Figure 15A The diagram shows the state in which the first hinge HIG1 and the second hinge HIG2 are coupled to the first hinge cover CV1 and the second hinge cover CV2, and... Figure 15BThe diagram shows the state where the first hinge HIG1 and the second hinge HIG2 are separated from each other by the first hinge cover CV1 and the second hinge cover CV2. Furthermore, Figure 15C The first hinge HIG1 and the second hinge HIG2 are shown in a state where they are separated from the central frame CFM.

[0181] Reference Figure 12 and Figure 15A The first hinge cover CV1 and the second hinge cover CV2 can be coupled to the first hinge HIG1 and the second hinge HIG2. A first coupling pin CP1 is embedded in a first fastening groove CGV1-1, which is defined in the lower surface of the first body BD1 so as to overlap with the first coupling pin CP1 in a plan view in the unfolded state, thereby allowing the first hinge cover CV1 to be coupled to the first hinge HIG1. A second coupling pin CP2 is embedded in a second fastening groove CGV1-2, which is defined in the lower surface of the second body BD2 so as to overlap with the second coupling pin CP2 in a plan view in the unfolded state, thereby allowing the second hinge cover CV2 to be coupled to the second hinge HIG2.

[0182] The center cover CCV can be coupled to the center frame CFM. For example, a coupling pin CP is embedded in a fastening groove CGV-2, which is defined in the lower surface of the center frame CFM to overlap with the coupling pin CP in the plan view in the unfolded state, so that the center cover CCV can be coupled to the center frame CFM.

[0183] The center frame CFM can be coupled to the first hinge HIG1 and the second hinge HIG2. A coupling pin PN can protrude downwards from the lower surface of the center frame CFM adjacent to the side opposite to the center cover CCV. The coupling pin PN is embedded in a fastening groove CGV-3, which is defined in the upper surfaces of the first body BD1 and the second body BD2 so as to overlap with the coupling pin PN in a plan view in the unfolded state, thereby allowing the center frame CFM to be coupled to the first hinge HIG1 and the second hinge HIG2.

[0184] The structure in which the first coupling pin CP1 and the second coupling pin CP2, as well as the coupling pins CP and PN, are embedded in the first fastening groove CGV1-1 and the second fastening groove CGV1-2 and the fastening grooves CGV-2 and CGV-3, can be the same as or similar to the structure in which the first coupling pin PN1 is embedded in the fastening groove CGV-1.

[0185] Reference Figure 15A and Figure 15BWhen the first coupling pin CP1 and the second coupling pin CP2 are separated from the first hinge HIG1 and the second hinge HIG2 due to a predetermined external force, the first hinge cover CV1 and the second hinge cover CV2 can be separated from the first hinge HIG1 and the second hinge HIG2.

[0186] Therefore, the first hinge cover CV1 and the second hinge cover CV2 can be detachably coupled to the first hinge HIG1 and the second hinge HIG2, respectively. The first hinge cover CV1 can be detachably coupled to the rear surface of the first hinge HIG1, and the second hinge cover CV2 can be detachably coupled to the rear surface of the second hinge HIG2. The first hinge cover CV1 can be detachably coupled to the first body BD1 of the first hinge HIG1. The second hinge cover CV2 can be detachably coupled to the second body BD2 of the second hinge HIG2.

[0187] Reference Figure 15B and Figure 15C A predetermined external force is applied downwards to the first hinge HIG1 and the second hinge HIG2, and the first hinge HIG1 and the second hinge HIG2 are detachable from the center frame CFM. The first hinge HIG1 and the second hinge HIG2 are also detachable from the coupling pin PN. Therefore, the first hinge HIG1 and the second hinge HIG2 are detachably coupled to the center frame CFM.

[0188] Figures 16 to 20 This is a view used to describe a method for repairing a display device according to an embodiment of the present invention.

[0189] The method for repairing the display device DD is essentially a method for replacing the first hinge HIG1 or the second hinge HIG2, and for example, in Figures 16 to 20 The display module DM is omitted (see...) Figure 11 ).

[0190] Reference Figure 16 The display device DD can be in a folded state. For example, the display device DD can be folded such that the first hinge HIG1 and the second hinge HIG2 cause the first support member SUP1 and the second support member SUP2 to rotate relative to the first rotation axis RX1 and the second rotation axis RX2. In the folded state, the third direction DR3 can be defined as a direction perpendicular to the plane including the first rotation axis RX1 and the second rotation axis RX2.

[0191] Reference Figure 15B and Figure 17 The first hinge cover CV1 can be separated from the first hinge HIG1. Additionally, the second hinge cover CV2 can also be separated from the second hinge HIG2.

[0192] If the folding operation of the display device DD is not performed correctly, it is suspected that the first hinge HIG1 and the second hinge HIG2 are defective. That is, the first hinge HIG1 or the second hinge HIG2 of the display device DD may be defective. In order to check whether the first hinge HIG1 and the second hinge HIG2 are defective, it is necessary to separate the first hinge cover CV1 and the second hinge cover CV2 that cover the first hinge HIG1 and the second hinge HIG2.

[0193] In an embodiment of this invention, the first hinge cover CV1 is separated from the first hinge HIG1, and thus the first hinge HIG1 can be inspected for defects. Furthermore, the second hinge cover CV2 is separated from the second hinge HIG2, and thus the second hinge HIG2 can be inspected for defects.

[0194] Reference Figure 18 and Figure 19 When the inspection results show that the first hinge HIG1 is defective, the defective first hinge D-HIG1 can be separated from the first support member SUP1 and the second support member SUP2 in the folded state.

[0195] Reference Figure 13B and Figure 18 The fastening unit CU can be separated from the first support member SUP1, the second support member SUP2, and the first rotating member ROP1 to separate the first hinge HIG1 from the first support member SUP1 and the second support member SUP2. The center cover CCV does not overlap with the first hinge HIG1 in the third direction DR3, so that the first hinge HIG1 can be separated from the first support member SUP1 and the second support member SUP2 without separating the center cover CCV.

[0196] Reference Figure 14B , Figure 15C and Figure 19 The first coupling pin PN1 can be separated from the first support member SUP1 and the second support member SUP2. Furthermore, the defective first hinge D-HIG1 can be separated from the central frame CFM. According to the above operation, the defective first hinge D-HIG1 can be separated from the first support member SUP1 and the second support member SUP2.

[0197] Reference Figure 20 A good first hinge N-HIG1 (e.g., a defect-free hinge) can be coupled to a first support member SUP1 and a second support member SUP2. Thereafter, a first hinge cover CV1, separated from the defective first hinge D-HIG1, can be coupled to the rear surface of the good first hinge N-HIG1.

[0198] Although not shown, when the second hinge HIG2 is defective, it can be replaced with a good second hinge HIG2 in the same manner as the first hinge HIG1 was replaced as described above.

[0199] In embodiments of this invention, when either the first hinge HIG1 or the second hinge HIG2 is defective, the defect can be more easily inspected by separating only the first hinge cover CV1 and the second hinge cover CV2, without having to disassemble the entire display device DD. Furthermore, when either the first hinge HIG1 or the second hinge HIG2 is defective, the defective hinge can be more easily replaced without disassembling the entire display device DD. Therefore, the display device DD can be repaired more easily.

[0200] Figure 21 It shows the coverage Figure 12 A view of the auxiliary cover of the cover component shown. Figure 22 and Figure 23 This is a view showing an auxiliary cover that is coupled to the cover component.

[0201] Reference Figure 12 and Figure 21 The auxiliary cover SCV can be disposed below the cover component CVP. The auxiliary cover SCV can be disposed below the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV.

[0202] Reference Figure 21 , Figure 22 and Figure 23 The coupling pin PN' can be driven from the auxiliary cover SCV toward the cover component CVP (see...) Figure 12 The fastening groove CGV' can be defined in the rear surface of the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV facing the auxiliary cover SCV. The fastening groove CGV' can overlap with the coupling pin PN'.

[0203] The coupling pin PN' is embedded in the fastening groove CGV', allowing the auxiliary cover SCV to be coupled to the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV. The auxiliary cover SCV covers the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV.

[0204] When the coupling pin PN' is separated from the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV, the auxiliary cover SCV can also be separated from the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV. Therefore, the auxiliary cover SCV can be detachably coupled to the first hinge cover CV1, the second hinge cover CV2, and the center cover CCV.

[0205] According to an embodiment of this invention, since the hinge covers of each hinge are separated from the hinge, the defective condition of each of the multiple hinges can be inspected. The defective hinge is separated from the display device, and then the normal hinge is coupled back to the display device. Thereafter, the hinge covers can be reconnected to the normal hinge. Therefore, repairs to the display device can be easily performed.
