[0031] The advantages and features of the present invention, as well as methods for achieving them, will become clearer with reference to the following detailed embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and can be realized in various different forms. The present embodiments are provided solely for the purpose of complete disclosure of the present invention and to fully convey the scope of the invention to those skilled in the art to which the present invention pertains. The present invention is defined solely by the scope of the claims.

[0032] When elements or layers are referred to as "on" another element or layer, this includes either being directly on top of or having intervening layers or elements. Similarly, when references are made to "below," "left," and "right," this includes either being directly adjacent to or having intervening layers or elements. Like reference numbers refer to like elements throughout the specification.

[0033] Although terms such as "first" and "second" are used to describe various components, it is understood that these components are not limited by these terms. These terms are used merely to distinguish one component from another. Therefore, it is understood that a "first" component referred to below may be a "second" component within the technical concept of the present invention.

[0034] The features of the various embodiments of the present invention may be partially or wholly combined or combined with one another, may be technically interlocked and driven in various ways, and may be implemented independently of one another or in conjunction with one another.

[0035] Hereinafter, specific embodiments will be described with reference to the accompanying drawings.

[0036] 1 and 2 are perspective views illustrating a display device according to an embodiment in an unfolded state and a folded state, respectively.

[0037] Referring to Figures 1 and 2, Figure 1 shows a first state of the display device 10 unfolded without being folded at the folding lines FL1 and FL2, and Figure 2 shows a second state of the display device 10 folded at the folding lines FL1 and FL2.

[0038] The display device 10 according to an embodiment is a device for displaying moving or still images, and can be used as a display screen for a variety of products, including portable electronic devices such as mobile phones, smartphones, tablet personal computers (PCs), smart watches, watch phones, mobile communication terminals, electronic organizers, electronic books, portable multimedia players (PMPs), navigation systems, and Ultra Mobile PCs (UMPCs), as well as televisions, notebook computers, monitors, billboards, and Internet of Things (IoT) devices.

[0039] In the drawings, the first direction DR1 is a direction aligned with one side of the display device 10 in a plan view, and may be, for example, the horizontal direction of the display device 10. The second direction DR2 is a direction aligned with the other side of the display device 10 that is in contact with the one side in a plan view, and may be the vertical direction of the display device 10. The third direction DR3 may be the thickness direction of the display device 10.

[0040] The planar shape of the display device 10 may be a quadrilateral shape such as a rectangle. Each corner of the display device 10 may have a right-angled planar shape or a rounded planar shape. The front surface of the display device 10 may include two short sides aligned in a first direction DR1 and two long sides aligned in a second direction DR2.

[0041] The display device 10 may include a display area DA and a non-display area NDA. The planar shape of the display area DA may follow the shape of the display device 10. For example, if the planar shape of the display device 10 is rectangular, the planar shape of the display area DA may also be rectangular.

[0042] The display area DA may be an area including a plurality of pixels that displays an image. The non-display area NDA may be an area that does not include pixels and therefore does not display an image. The non-display area NDA may be arranged around the display area DA. The non-display area NDA is arranged to surround the display area DA, but the embodiments of the present specification are not limited to this. The display area DA may be partially surrounded by the non-display area NDA.

[0043] The display device 10 can maintain both a first state, which is an unfolded state, and a second state, which is a folded state. In one embodiment, the display device 10 can be folded in an in-folding manner so that the display areas DA face each other, as shown in FIG. 2. In this case, the front faces of the display devices 10 face each other when folded. In another embodiment, the display device 10 can be folded in an out-folding manner so that the rear faces face each other.

[0044] Display device 10 may include a folding area FDA, a first non-folding area NFA1, and a second non-folding area NFA2. The folding area FDA is an area where display device 10 bends or folds, and the first non-folding area NFA1 and the second non-folding area NFA2 may be areas where display device 10 does not bend or fold. In one embodiment, the first non-folding area NFA1 and the second non-folding area NFA2 may be flat areas of display device 10.

[0045] The first non-folding area NFA1 is located on one side of the folding area FDA, for example, the left side. The second non-folding area NFA2 is located on the other side of the folding area FDA, for example, the right side. The folding area FDA is an area defined by a first folding line FL1 and a second folding line FL2, and may be an area where the display device 10 bends with a predetermined curvature. The first folding line FL1 may be the boundary between the folding area FDA and the first non-folding area NFA1, and the second folding line FL2 may be the boundary between the folding area FDA and the second non-folding area NFA2.

[0046] 1 and 2, the first folding line FL1 and the second folding line FL2 extend in the second direction DR2, and in this case, the display device 10 can be folded based on the second direction DR2. This reduces the length of the display device 10 in the first direction DR1 by approximately half, making it convenient for users to carry the display device 10.

[0047] Here, the left side means one side in the first direction DR1, and the right side means the other side in the first direction DR1.

[0048] When the first folding line FL1 and the second folding line FL2 extend in the second direction DR2 as shown in Figures 1 and 2, the length of the folding region FDA in the second direction DR2 may be longer than the length of the first direction DR1. Also, the length of the first non-folding region NFA1 in the second direction DR2 may be longer than the length of the first non-folding region NFA1 in the first direction DR1. The length of the second non-folding region NFA2 in the second direction DR2 may be longer than the length of the second non-folding region NFA2 in the first direction DR1.

[0049] The display area DA and the non-display area NDA may each overlap at least one of the folding area FDA, the first non-folding area NFA1, and the second non-folding area NFA2. Figures 1 and 2 show that the display area DA and the non-display area NDA overlap the folding area FDA, the first non-folding area NFA1, and the second non-folding area NFA2, respectively.

[0050] Figure 3 is a perspective view showing a display device according to another embodiment in an unfolded state, and Figure 4 is a perspective view showing a display device according to another embodiment in a folded state.

[0051] Referring to Figures 3 and 4 in addition to Figures 1 and 2, Figure 3 shows a first state of display device 10 unfolded without folding at folding lines FL1 and FL2, and Figure 4 shows a second state of display device 10 folded at folding lines FL1 and FL2.

[0052] In the embodiment of Figures 3 and 4, the first folding line FL1 and the second folding line FL2 extend in the first direction DR1, and the display device 10 is folded in the second direction DR2, so the length of the display device 10 in the second direction DR2 is reduced to approximately half, and this is the only difference from the embodiment of Figures 1 and 2. Therefore, in the description of Figures 3 and 4, content that overlaps with the embodiment of Figures 1 and 2 will be omitted.

[0053] In the first unfolded state of the display device 10, the long sides of the display device 10 may extend along the second direction DR2, and the short sides of the display device 10 may extend along the first direction DR1.

[0054] As shown in FIGS. 3 and 4, the first folding line FL1 and the second folding line FL2 extend in a first direction DR1, and in this case, the display device 10 can be folded with reference to the first direction DR1.

[0055] The first non-folding area NFA1 is disposed on one side, e.g., the lower side, of the folding area FDA. The second non-folding area NFA2 is disposed on the other side, e.g., the upper side, of the folding area FDA. Here, the upper side refers to one side in the second direction DR2, and the lower side refers to the other side in the second direction DR2.

[0056] When the first folding line FL1 and the second folding line FL2 extend in a first direction DR1 as shown in Figures 3 and 4, the length of the folding region FDA in the first direction DR1 may be longer than the length of the second direction DR2. Also, the length of the first non-folding region NFA1 in the second direction DR2 may be longer than the length of the first non-folding region NFA1 in the first direction DR1. The length of the second non-folding region NFA2 in the second direction DR2 may be longer than the length of the second non-folding region NFA2 in the first direction DR1.

[0057] For the sake of convenience, the following description will be given using the embodiment of Figures 3 and 4 as an example, but this is not limiting, and the following content can be similarly applied to the embodiment of Figures 1 and 2.

[0058] FIG. 5 is a cross-sectional view showing a display device according to an embodiment.

[0059] Referring to FIG. 5, a display device 10 according to one embodiment may include a cover window CCW, an upper protection member 100, a window member 200, an optical member 300, a display panel 400, a panel protection member 500, a barrier film 600, a panel support member 700, an adhesive member 800, a lower visibility prevention member LPU, a digitizer member 900, a metal support member 1000, a buffer member 1100, and a penetration prevention member 1200.

[0060] The display panel 400 may be a panel for displaying images. The display panel 400 may be an organic light-emitting display panel including an organic light-emitting layer, a quantum dot light-emitting display panel including a quantum dot light-emitting layer, an inorganic light-emitting display panel using inorganic semiconductor elements as light-emitting elements, or a micro light-emitting display panel using micro light-emitting diodes as light-emitting elements. The following description focuses on the display panel 400 being an organic light-emitting display panel, but is not limited thereto. A detailed structure of the display panel 400 will be described later with reference to FIG. 6.

[0061] The optical member 300 is disposed on one surface of the display panel 400. For example, the optical member 300 is disposed on the upper surface of the display panel 400. The optical member 300 may include a polarizing film and / or a retardation film. The optical member 300 can reduce external light reflection.

[0062] The window member 200 is disposed on the optical member 300. The window member 200 is made of a transparent material, such as glass or plastic. For example, the window member 200 may be ultra-thin glass (UTG) with a thickness of 0.1 mm or less, or a transparent polyimide film.

[0063] The upper protection member 100 is disposed on the window member 200. The upper protection member 100 performs at least one of the functions of preventing shattering, absorbing impact, preventing scratches, preventing fingerprints, and preventing glare for the window member 200. The upper protection member 100 may include at least one of polyacrylate, polyethylene terephthalate (PET), and polyimide (PI).

[0064] The cover window CCW is disposed on the upper protection member 100. The cover window CCW may be a protective film for protecting the display device 10 from external impact. The cover window CCW may be attached to or detached from the display device 10 via an adhesive member. That is, the cover window CCW may be a changeable window, i.e., a replaceable window. In one embodiment, the cover window CCW may include at least one of flexible polyethylene terephthalate (PET) and thermoplastic polyurethane (TPU), but is not limited thereto.

[0065] The panel protection member 500 is disposed on the other surface of the display panel 400. For example, the panel protection member 500 is disposed on the bottom surface of the display panel 400. The panel protection member 500 can support the display panel 400 and protect the bottom surface of the display panel 400. The panel protection member 500 can be made of plastic such as polyethylene terephthalate (PET) or polyimide. Although the drawings show the panel protection member 500 also disposed in the folding region FDA of the display device 10, the embodiment of the present specification is not limited thereto. For example, the panel protection member 500 can be removed from the folding region FDA of the display device 10 to allow the display device 10 to be folded smoothly.

[0066] The panel protection member 500 is provided together with the display panel 400 during the manufacturing process of the display panel 400. For example, the panel protection member 500 is provided in a state of being attached to the display panel 400 in order to protect the display panel 400 during the manufacturing process of the display panel 400. Thereafter, with the display panel 400 and the panel protection member 500 attached, components arranged above the display panel 400 and components arranged below the panel protection member 500 are attached by a module process.

[0067] The barrier film 600 is disposed on the panel protection member 500. For example, the barrier film 600 is disposed on the lower surface of the panel protection member 500. The barrier film 600 may be a member for enhancing the impact resistance of the display device 10. In some embodiments, the barrier film 600 may include a support layer 610 (see FIG. 7) for enhancing the impact resistance, and adhesive layers (620, 630, see FIG. 7) disposed on the top and bottom of the support layer 610 (see FIG. 7).

[0068] In the display device 10 according to this embodiment, the barrier film 600 may be attached onto the panel protection member 500 during a module process after the manufacturing process of the display panel 400. Unlike the panel protection member 500 that is attached to protect the display panel 400, the barrier film 600 may be a film that is separately attached during the module process to enhance the impact resistance of the display device 10. For example, the barrier film 600 may have a different thickness (e.g., height in the third direction DR3) from that of the panel protection member 500.

[0069] The panel support member 700 is disposed on the barrier film 600. For example, the panel support member 700 is disposed on the lower surface of the barrier film 600. The panel support member 700 may be a rigid member whose shape and volume do not easily change due to external pressure. The panel support member 700 is disposed on the lower surface of the display panel 400 and is a rigid member whose shape and volume do not easily change due to external pressure, so that it can support the display panel 400.

[0070] In one embodiment, the panel support member 700 may be a polymer containing carbon fiber or glass fiber. In this case, the panel support member 700 is formed of a polymer containing carbon fiber or glass fiber, and therefore can pass the magnetic field or electromagnetic signal of the digitizer member 900. Therefore, it is possible to provide a panel support member 700 that can support the display panel 400 without reducing the touch sensitivity of the digitizer member 900.

[0071] In another embodiment, the panel support member 700 may be a metal plate. For example, the panel support member 700 may be made of a metal or a metal alloy, such as a metal plate. The panel support member 700 may include, but is not limited to, copper (Cu), aluminum (Al), stainless steel (SUS), and / or alloys thereof.

[0072] The panel support member 700 may include a differential pattern disposed in the folding region FDA to facilitate bending in the folding region FDA. By including the differential pattern disposed in the folding region FDA, the panel support member 700 can easily bend when folding the display device 10. The panel support member 700 and its differential pattern will be described later with reference to FIG. 8, etc.

[0073] The lower view preventing member LPU is disposed on the panel support member 700. For example, the lower view preventing member LPU is disposed on the lower surface of the panel support member 700. The lower view preventing member LPU may be disposed to overlap the folding region FDA. The lower view preventing member LPU may be disposed in the same layer as the adhesive member 800. The lower view preventing member LPU may be disposed between the first adhesive member 810 and the second adhesive member 820. The lower view preventing member LPU can prevent the lattice pattern of the panel support member 700 from being seen from the outside. In addition, the lower view preventing member LPU may include a flexible material to reduce folding stress of the display device 10. For example, the lower view preventing member LPU may include thermoplastic polyurethane (TPU).

[0074] The adhesive member 800 is disposed on the panel support member 700. For example, the adhesive member 800 is disposed on the lower surface of the panel support member 700. The adhesive member 800 is disposed between the panel support member 700 and the digitizer member 900. The panel support member 700 and the digitizer member 900 can be bonded to each other via the adhesive member 800. The adhesive member 800 can include a transparent adhesive such as a pressure-sensitive adhesive (PSA) or an optically clear adhesive (OCA). The adhesive member 800 can include an acrylic adhesive material.

[0075] In some embodiments, the adhesive member 800 may include a first adhesive member 810 overlapping the first digitizer member 910 and a second adhesive member 820 overlapping the second digitizer member 920. The first adhesive member 810 and the second adhesive member 820 may be spaced apart from each other with the lower visibility preventing member LPU therebetween.

[0076] The digitizer member 900 is disposed on the panel support member 700. For example, the digitizer member 900 is disposed on the lower surface of the panel support member 700. The digitizer member 900 may include a first digitizer member 910 and a second digitizer member 920. The first digitizer member 910 and the second digitizer member 920 are attached to the lower surface of the panel support member 700 by a first adhesive member 810 and a second adhesive member 820, respectively.

[0077] The first digitizer member 910 and the second digitizer member 920 may not be disposed in the folding area FDA to reduce folding stress of the display device 10. The first digitizer member 910 is disposed in the first non-folding area NFA1, and the second digitizer member 920 is disposed in the second non-folding area NFA2. A gap between the first digitizer member 910 and the second digitizer member 920 overlaps the folding area FDA and may be smaller than the width of the folding area FDA. The width of the folding area FDA may be the length of the folding area FDA in the second direction DR2.

[0078] The first digitizer member 910 and the second digitizer member 920 may include an electrode pattern for detecting the approach or contact of an electronic pen, such as a stylus pen that supports electromagnetic resonance (EMR). The first digitizer member 910 and the second digitizer member 920 detect a magnetic field or an electromagnetic signal emitted from the electronic pen based on the electrode pattern, and determine the point where the detected magnetic field or electromagnetic signal is strongest as the touch coordinate.

[0079] Magnetic metal powder may be disposed on the lower surface of the first digitizer member 910 and the lower surface of the second digitizer member 920. In this case, the magnetic field or electromagnetic signal that passes through the first digitizer member 910 and the second digitizer member 920 can flow inside the magnetic metal powder. Therefore, the magnetic metal powder can reduce the magnetic field or electromagnetic signal from the first digitizer member 910 and the second digitizer member 920 from being emitted to the lower surface of the display device 10.

[0080] In some embodiments, the digitizer member 900 can be omitted.

[0081] The metal support member 1000 may include a first metal support member 1010 and a second metal support member 1020. The first metal support member 1010 is disposed on the lower surface of the first digitizer member 910, and the second metal support member 1020 is disposed on the lower surface of the second digitizer member 920.

[0082] The first metal support member 1010 and the second metal support member 1020 do not have to be arranged in the folding area FDA to reduce folding stress of the display device 10. The first metal support member 1010 is arranged in the first non-folding area NFA1, and the second metal support member 1020 is arranged in the second non-folding area NFA2. The gap between the first metal support member 1010 and the second metal support member 1020 overlaps the folding area FDA and may be smaller than the width of the folding area FDA.

[0083] The first metal support member 1010 and the second metal support member 1020 may include a material having high rigidity to support the first digitizer member 910 and the second digitizer member 920. For example, the first metal support member 1010 and the second metal support member 1020 may include stainless steel such as SUS316.

[0084] The buffer member 1100 may include a first buffer member 1110 and a second buffer member 1120. The first buffer member 1110 and the second buffer member 1120 can absorb external impacts to prevent damage to the panel support member 700 and the digitizer member 900. The first buffer member 1110 and the second buffer member 1120 may include an elastic material such as a sponge formed by foaming rubber, a urethane-based material, or an acrylic-based material.

[0085] The first buffer member 1110 is disposed on the lower surface of the first metal support member 1010, and the second buffer member 1120 is disposed on the lower surface of the second metal support member 1020. The first buffer member 1110 and the second buffer member 1120 do not have to be disposed in the folding area FDA to reduce folding stress of the display device 10. The first buffer member 1110 is disposed in the first non-folding area NFA1, and the second buffer member 1120 is disposed in the second non-folding area NFA2. The gap between the first buffer member 1110 and the second buffer member 1120 overlaps the folding area FDA and may be smaller than the width of the folding area FDA.

[0086] The permeation prevention members 1200 are disposed on the lower surfaces of the first metal support member 1010 and the second metal support member 1020. The permeation prevention members 1200 are disposed on the edges of the first metal support member 1010 and the second metal support member 1020. Although the drawings show the permeation prevention members 1200 being disposed on both sides of the first buffer member 1110 and the second buffer member 1120, the present invention is not limited thereto. For example, the permeation prevention members 1200 may be disposed to surround the first buffer member 1110 and the second buffer member 1120.

[0087] The permeation prevention member 1200 may be a waterproof tape or a waterproof member attached to the front surface of a frame disposed on the lower surface of the first metal support member 1010 and the lower surface of the buffer member 1100. Thus, the permeation prevention member 1200 can prevent moisture and dust from permeating into the display device 10. In other words, a waterproof and dustproof display device 10 can be provided.

[0088] In another embodiment, the permeation prevention member 1200 may not surround the first buffer member 1110 and the second buffer member 1120, but may be arranged to overlap in the third direction DR3 with the magnets that maintain the folding of the display device 10. In this case, the permeation prevention member 1200 may function as a magnetic shielding member that can shield magnetism to prevent the digitizer member 900 or the display panel 400 from being affected by the magnetism of the magnets.

[0089] FIG. 6 is a cross-sectional view showing an example of a display panel according to an embodiment.

[0090] 6, the display panel 400 may include a substrate SUB, a display layer DISL disposed on the substrate SUB, and a touch sensing layer TDL disposed on the display layer DISL. The display layer DISL may include a thin film transistor layer TFTL, a light-emitting element layer EML, and an encapsulation layer TFEL.

[0091] A thin-film transistor layer TFTL is disposed on the substrate SUB. The thin-film transistor layer TFTL may include a barrier film BR, a thin-film transistor TFT1, a first capacitor electrode CAE1, a second capacitor electrode CAE2, a first anode connecting electrode ANDE1, a second anode connecting electrode ANDE2, a gate insulating film 130, a first interlayer insulating film 141, a second interlayer insulating film 142, a first planarization film 160, and a second planarization film 180.

[0092] The substrate SUB is made of an insulating material such as a polymer resin. For example, the substrate SUB is made of polyimide. The substrate SUB may be a flexible substrate that allows bending, folding, rolling, and the like.

[0093] A barrier film BR is disposed on the substrate SUB. The barrier film BR is a film for protecting the thin film transistors of the thin film transistor layer TFTL and the light-emitting layer 172 of the light-emitting element layer EML from moisture that may penetrate through the substrate SUB, which is susceptible to moisture permeation. The barrier film BR is made of a plurality of inorganic films alternately stacked. For example, the barrier film BR may be formed as a multilayer film in which one or more inorganic films selected from the group consisting of silicon nitride layers, silicon oxynitride layers, silicon oxide layers, titanium oxide layers, and aluminum oxide layers are alternately stacked.

[0094] The thin film transistor TFT1 is disposed on the barrier film BR. The active layer ACT1 of the thin film transistor TFT1 is disposed on the barrier film BR. The active layer ACT1 of the thin film transistor TFT1 may include polycrystalline silicon, single crystal silicon, low-temperature polycrystalline silicon, amorphous silicon, or an oxide semiconductor.

[0095] The active layer ACT1 may include a channel region CHA1, a source region TS1, and a drain region TD1. The channel region CHA1 may be a region overlapping with the gate electrode TG1 in a third direction DR3, which is a thickness direction of the substrate SUB. The source region TS1 may be disposed on one side of the channel region CHA1, and the drain region TD1 may be disposed on the other side of the channel region CHA1. The source region TS1 and the drain region TD1 may be regions that do not overlap with the gate electrode TG1 in the third direction DR3. The source region TS1 and the drain region TD1 may be regions that are made of a silicon semiconductor or an oxide semiconductor doped with ions or impurities to have conductivity.

[0096] A gate insulating film 130 is disposed on the active layer ACT1 of the thin film transistor TFT1. The gate insulating film 130 may be formed of an inorganic film, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer.

[0097] The gate electrode TG1 and the first capacitor electrode CAE1 of the thin film transistor TFT1 are disposed on the gate insulating film 130. The gate electrode TG1 may overlap the channel region CHA1 in the third direction DR3. Although FIG. 6 shows the gate electrode TG1 and the first capacitor electrode CAE1 spaced apart from each other, they may also be connected to each other and formed as a single unit. The gate electrode TG1 and the first capacitor electrode CAE1 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0098] A first interlayer insulating film 141 is disposed on the gate electrode TG1 of the thin film transistor TFT1 and the first capacitor electrode CAE1. The first interlayer insulating film 141 may be formed of an inorganic film, such as a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. The first interlayer insulating film 141 may be formed of a plurality of inorganic films.

[0099] A second capacitor electrode CAE2 is disposed on the first interlayer insulating film 141. The second capacitor electrode CAE2 may overlap the first capacitor electrode CAE1 of the thin film transistor TFT1 in the third direction DR3. When the gate electrode TG1 and the first capacitor electrode CAE1 are integrally formed, the second capacitor electrode CAE2 may overlap the gate electrode TG1 in the third direction DR3. Because the first interlayer insulating film 141 has a predetermined dielectric constant, a capacitor may be formed by the first capacitor electrode CAE1, the second capacitor electrode CAE2, and the first interlayer insulating film 141 disposed therebetween. The second capacitor electrode CAE2 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0100] A second interlayer insulating film 142 is disposed on the second capacitor electrode CAE2. The second interlayer insulating film 142 may be formed of an inorganic film, such as a silicon nitride film, a silicon oxynitride film, a silicon oxide film, a titanium oxide film, or an aluminum oxide film. The second interlayer insulating film 142 may be formed of multiple inorganic films.

[0101] A first anode connecting electrode ANDE1 is disposed on the second interlayer insulating film 142. The first anode connecting electrode ANDE1 may be connected to the drain region TD1 of the thin film transistor TFT1 via a first connection contact hole ANCT1 that penetrates the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142. The first anode connecting electrode ANDE1 may be formed of a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0102] A first planarization film 160 for planarizing a step caused by the thin film transistor TFT1 is disposed on the first anode connecting electrode ANDE1. The first planarization film 160 may be formed of an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0103] A second anode connecting electrode ANDE2 is disposed on the first planarization film 160. The second anode connecting electrode ANDE2 may be connected to the first anode connecting electrode ANDE1 via a second connection contact hole ANCT2 penetrating the first planarization film 160. The second anode connecting electrode ANDE2 may be formed of a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0104] A second planarization film 180 is disposed on the second anode connecting electrode ANDE2. The second planarization film 180 may be formed of an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0105] A light emitting element layer EML including a light emitting element LEL and a bank 190 is disposed on the second planarization film 180. Each of the light emitting elements LEL includes a pixel electrode 171, a light emitting layer 172, and a common electrode 173.

[0106] The pixel electrode 171 is disposed on the second planarization film 180. The pixel electrode 171 may be connected to the second anode connection electrode ANDE2 via a third connection contact hole ANCT3 that penetrates the second planarization film 180.

[0107] In a top emission structure in which light is emitted toward the common electrode 173 from the light emitting layer 172, the pixel electrode 171 may be formed of a metal material with high reflectivity, such as a laminated structure of aluminum (Al) and titanium (Ti) (Ti / Al / Ti), a laminated structure of aluminum (Al) and indium tin oxide (ITO) (ITO / Al / ITO), a laminated structure of silver (Ag) and indium tin oxide (ITO) (ITO / Ag / ITO), an APC alloy, and a laminated structure of an APC alloy and ITO (ITO / APC / ITO). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu).

[0108] The banks 190 may be formed on the second planarization film 180 to partition the pixel electrodes 171 in order to define the light emitting portions EA1 and EA2. The banks 190 are disposed to cover the edges of the pixel electrodes 171. The banks 190 may be formed of an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0109] Each of the first light-emitting section EA1 and the second light-emitting section EA2 refers to an area in which a pixel electrode 171, a light-emitting layer 172, and a common electrode 173 are stacked in sequence, and light is emitted by holes from the pixel electrode 171 and electrons from the common electrode 173 recombining in the light-emitting layer 172.

[0110] An emitting layer 172 is disposed on the pixel electrode 171 and the bank 190. The emitting layer 172 contains an organic material and emits light of a predetermined color. For example, the emitting layer 172 may include a hole transporting layer, an organic material layer, and an electron transporting layer.

[0111] The common electrode 173 is disposed on the light emitting layer 172. The common electrode 173 may be disposed to cover the light emitting layer 172. The common electrode 173 may be a common layer formed in common to the first light emitting unit EA1 and the second light emitting unit EA2.

[0112] In the top emission structure, the common electrode 173 may be made of a transparent metal material (TCO, Transparent Conductive Material) such as ITO or IZO, or a semi-transmissive metal material such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). When the common electrode 173 is made of a semi-transmissive metal material, microcavities increase light output efficiency.

[0113] Spacers 191 are disposed on the banks 190. The spacers 191 may serve to support a mask during a manufacturing process for manufacturing the light-emitting layer 172. The spacers 191 may be formed of an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0114] In some embodiments, the display panel 400 may further include a capping layer CPL disposed on the common electrode 173. The capping layer CPL may include an inorganic material. For example, the capping layer CPL may include at least one of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, titanium oxide, tin oxide, cerium oxide, and silicon oxynitride.

[0115] An encapsulation layer TFEL is disposed on the common electrode 173. The encapsulation layer TFEL may include at least one inorganic film to prevent oxygen or moisture from penetrating into the light-emitting element layer EML. The encapsulation layer TFEL may also include at least one organic film to protect the light-emitting element layer EML from foreign matter such as dust. For example, the encapsulation layer TFEL may include a first encapsulation inorganic film TFE1, an encapsulation organic film TFE2, and a second encapsulation inorganic film TFE3.

[0116] The first sealing inorganic film TFE1 is disposed on the common electrode 173, the sealing organic film TFE2 is disposed on the first sealing inorganic film TFE1, and the second sealing inorganic film TFE3 is disposed on the sealing organic film TFE2. The first sealing inorganic film TFE1 and the second sealing inorganic film TFE3 may be formed of a multi-layer structure in which one or more inorganic films selected from the group consisting of silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, and aluminum oxide are alternately stacked. The sealing organic film TFE2 may be an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0117] The touch sensing layer TDL is disposed on the encapsulation layer TFEL and includes a first touch insulating film TINS1, a connection electrode BE, a second touch insulating film TINS2, a driving electrode TE, a sensing electrode RE, and a third touch insulating film TINS3.

[0118] The first touch insulating film TINS1 is disposed on the encapsulation layer TFEL and may be formed of an inorganic film, such as a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer.

[0119] A connection electrode BE is disposed on the first touch insulating film TINS1.

[0120] A second touch insulating film TINS2 is disposed on the connection electrode BE.

Alternatively, the second touch insulating film TINS2 may be formed of an organic film, such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0121] The driving electrode TE and the sensing electrode RE are disposed on the second touch insulating film TINS2. The driving electrode TE and the sensing electrode RE may be formed of a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0122] The driving electrodes TE and the sensing electrodes RE may overlap with the connection electrodes BE in the third direction DR3. The driving electrodes TE may be connected to the connection electrodes BE via touch contact holes TCNT1 that penetrate the first touch insulating film TINS1.

[0123] A third touch insulating film TINS3 is formed on the driving electrodes TE and the sensing electrodes RE. The third touch insulating film TINS3 can flatten steps formed by the driving electrodes TE, the sensing electrodes RE, and the connection electrodes BE. The third touch insulating film TINS3 can be formed of an organic film such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0124] Fig. 7 is an enlarged view of area A in Fig. 5. Fig. 8 is a plan view showing a panel support member according to one embodiment. Fig. 9 is a cross-sectional view taken along line X1-X1' in Fig. 8. Fig. 7 is a view seen from the first direction DR1, Fig. 8 is a view seen from the third direction DR3, and Fig. 9 is a view seen from the second direction DR2.

[0125] 7-9 in addition to FIG. 5, a barrier film 600 can include a support layer 610, a first adhesive layer 620, and a second adhesive layer 630.

[0126] The support layer 610 can enhance the impact resistance of the display device 10. The support layer 610 can include polyethylene terephthalate (PET) or polyimide.

[0127] A first adhesive layer 620 is disposed on the upper surface of the support layer 610. A second adhesive layer 630 is disposed on the lower surface of the support layer 610. The first adhesive layer 620 and the second adhesive layer 630 may comprise a transparent adhesive, such as a pressure sensitive adhesive (PSA) or an optically clear adhesive (OCA). The first adhesive layer 620 and the second adhesive layer 630 may comprise an acrylic adhesive material.

[0128] In the display device 10 according to this embodiment, the support layer 610, the first adhesive layer 620, and the second adhesive layer 630 may be disposed across the folding region FDA and the non-folding regions NFA1 and NFA2. For example, the support layer 610, the first adhesive layer 620, and the second adhesive layer 630 may be seamlessly connected from the folding region FDA to the non-folding regions NFA1 and NFA2, respectively. Therefore, even if the panel support member 700 includes a differential pattern in the folding region FDA, as described below, the impact resistance of the display device 10 can be enhanced in the folding region FDA. In addition, the differential pattern of the panel support member 700 can be prevented from being visible from above the display device 10.

[0129] The panel support member 700 may include a first support 710 and a second support 720. The first support 710 is disposed in the first non-folding area NFA1 and the folding area FDA, and the second support 720 is disposed in the second non-folding area NFA2 and the folding area FDA. The first support 710 and the second support 720 may be spaced apart from each other in the second direction DR2.

[0130] The first support 710 and the second support 720 may each include a differential pattern. For example, the first support 710 may include a first differential pattern 715, and the second support 720 may include a second differential pattern 725. The first differential pattern 715 and the second differential pattern 725 may each be disposed in the folding region FDA. The first differential pattern 715 and the second differential pattern 725 may be portions that are folded when the display device 10 is folded.

[0131] A portion of the first support 710 excluding the first differential pattern 715 (e.g., a first body) and a portion of the second support 720 excluding the second differential pattern 725 (e.g., a second body) may be portions that are not folded when folding the display device 10. The first differential pattern 715 protrudes from the first body in the second direction DR2, and the second differential pattern 725 protrudes from the second body in the opposite direction to the second direction DR2. The first differential pattern 715 and the second differential pattern 725 face each other in the second direction DR2.

[0132] The first and second differential patterns 715 and 725 may include first and second spacers 715a and 725a and 715b and 725b, respectively. The first and second spacers 715a and 725a and 715b and 725b may have different heights. For example, the height H1 of the first spacers 715a and 725a may be greater than the height H2 of the second spacers 715b and 725b. The different heights of the first and second spacers 715a and 725a and 715b and 725b may be formed by half etching or photolithography.

[0133] The first spacers 715a, 725a and the second spacers 715b, 725b may extend in the second direction DR2 and the third direction DR3. For example, the first spacers 715a, 725a and the second spacers 715b, 725b may protrude from the first body and the second body in the second direction DR2 (or the opposite direction) and have a height in the third direction DR3 (e.g., a rectangular parallelepiped shape).

[0134] In some embodiments, the first spacers 715a, 725a and the second spacers 715b, 725b may be arranged alternately in the first direction DR1. The first spacers 715a, 725a and the second spacers 715b, 725b may be spaced apart in the first direction DR1. A hole HOL is arranged between the spaced-apart first spacers 715a, 725a and second spacers 715b, 725b. By spacing the first spacers 715a, 725a and the second spacers 715b, 725b apart, stress applied when folding the display device 10 can be minimized.

[0135] However, this is not limiting, and the arrangement of the first spacers 715a, 725a and the second spacers 715b, 725b may be irregular. For example, the first spacers 715a, 725a may be arranged twice, followed by the second spacers 715b, 725b, once, and then the first spacers 715a, 725a, once, and then the second spacers 715b, 725b, once. That is, one set of first spacers 715a, 725a may be arranged along the second direction DR2, and another set of first spacers 715a, 725a may be arranged along the second direction DR2 on the first direction DR1 side. Then, one set of second spacers 715b, 725b may be arranged along the second direction DR2 on the first direction DR1 side of these two sets of first spacers 715a, 725a. Furthermore, one set of first spacers 715a and 725a along the second direction DR2 is arranged on the first direction DR1 side. Furthermore, the first spacers 715a, 725a do not need to be arranged along the second direction DR2, and may be arranged at positions offset in the second direction DR2. Similarly, the second spacers 715b, 725b may be arranged at positions offset in the second direction DR2. That is, each of the first differential pattern 715 and the second differential pattern 725 may include at least one first spacer 715a, 725a and at least one second spacer 715b, 725b. In this case, the number and arrangement order of the first spacers 715a, 725a and the second spacers 715b, 725b are not limited. Here, the first body of the first support 710 and the second body of the second support 720 do not have holes HOL, unlike the configuration in which the first spacers 715a, 725a and the second spacers 715b, 725b have holes HOL.

[0136] 8, the holes HOL of the first support 710 and the holes HOL of the second support 720 are arranged side by side in the second direction DR2, but this is not limiting. For example, the holes HOL of the first support 710 may be arranged side by side with the first spacers 715a and 725a and the second spacers 715b and 725b of the second support 720 in the second direction DR2.

[0137] 9, the upper surfaces of the first spacers 715a and 725a may be in direct contact with the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surfaces of the first spacers 715a and 725a may be in direct contact with the upper surface of the lower view preventing member LPU. The upper surfaces of the second spacers 715b and 725b may be spaced apart from the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surfaces of the second spacers 715b and 725b may be in direct contact with the upper surface of the lower view preventing member LPU. In other embodiments, the upper surfaces of the second spacers 715b and 725b may be in direct contact with the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surfaces of the second spacers 715b and 725b may be spaced apart from the upper surface of the lower view preventing member LPU.

[0138] In some embodiments, the width LPU_L of the lower visibility preventing member LPU may be greater than the width of the differential patterns 715, 725 in the second direction DR2. For example, the width LPU_L of the lower visibility preventing member LPU may be greater than the width of the folding region FDA in the second direction DR2. The lower visibility preventing member LPU may be arranged not only in the folding region FDA but also in the non-folding regions NFA1, NFA2. The lower visibility preventing member LPU can prevent the grid pattern of the first support 710 and the second support 720, i.e., the pattern formed by the first spacers 715a, 725a and the second spacers 715b, 725b arranged on either side of the hole HOL, from being visible from the outside.

[0139] In the display device 10 according to this embodiment, the first differential pattern 715 and the second differential pattern 725 include first spacers 715a, 725a and second spacers 715b, 725b having different heights, respectively, thereby enhancing the impact resistance of the display device 10. For example, as described above, the support layer 610 and adhesive layers 620, 630 of the barrier film 600 are disposed across the folding region FDA and the non-folding regions NFA1, NFA2, thereby enhancing the impact resistance of the display device 10. Furthermore, when an impact is applied to the top of the display device 10, a portion of the barrier film 600 is supported by the first spacers 715a, 725a to disperse the impact, and another portion of the barrier film 600 is further disperse the impact due to an air gap between the second spacers 715b, 725b and the barrier film 600. Furthermore, air can freely circulate through the holes HOL between the first spacers 715a, 725a and the second spacers 715b, 725b, further improving the cushioning effect of the air gap. More specifically, the first spacers 715a, 725a are arranged across the lower surface of the barrier film 600 (an example of an upper component of a spacer) and the upper surface of the lower visibility preventing member LPU (an example of a lower component of a spacer), and are arranged in a dispersed manner in a plan view. Therefore, an impact applied to the upper part of the display device 10 is transmitted from the barrier film 600 to the first spacers 715a, 725a. Since the multiple first spacers 715a, 725a are arranged in a dispersed manner, the impact can be dispersed by the multiple first spacers 715a, 725a. Furthermore, the second spacers 715b, 725b are not arranged across the lower surface of the barrier film 600 and the upper surface of the lower visibility preventing member LPU, but are arranged with a gap between them and the lower surface of the barrier film 600 or the upper surface of the lower visibility preventing member LPU. The second spacers 715b and 725b can also disperse an impact applied to the upper part of the display device 10. For example, the second spacers 715b and 725b can indirectly receive and disperse an impact transmitted to the barrier film 600, the first spacers 715a and 725a, the lower visibility preventing member LPU, etc.For example, the second spacers 715b, 725b receive and disperse impacts received by the barrier film 600 via the first spacers 715a, 725a and the lower visibility preventing member LPU. Furthermore, for example, since one end of the second spacers 715b, 725b is free, the second spacers 715b, 725b themselves can oscillate to disperse the impact. Furthermore, the arrangement of multiple second spacers 715b, 725b can also disperse the impact. Furthermore, as described above, air can circulate freely through the holes HOL. When an impact is applied to the upper part of the display device 10, a large amount of pressure is applied to the impacted area. However, the air from the impacted area circulates to other areas, thereby cushioning the impact and further improving the cushioning effect of the air gap. Furthermore, the differential patterns 715 and 725 have the spacers 715a, 725a, 715b, and 725b with the holes HOL interposed therebetween, which makes it easier to suppress the folding stress of the display device 10 in the folding region FDA.

[0140] In the following, other embodiments of the display device according to the embodiment will be described. In the following embodiments, the same reference numerals will be used for the same components as those in the above-described embodiment, and the description will be omitted or simplified, focusing on the differences.

[0141] Fig. 10 is a plan view showing a panel support member according to another embodiment. Fig. 11 is a cross-sectional view taken along X2-X2' in Fig. 10. Fig. 10 is a view seen from the third direction DR3, and Fig. 11 is a view seen from the second direction DR2.

[0142] Referring to Figures 10 and 11, the display device 10 according to this embodiment differs from the display device 10 according to the embodiment described with reference to Figure 7, etc., in that it further includes bottom portions 715c, 725c and includes grooves GRV instead of holes HOL.

[0143] More specifically, the first and second differential patterns 715 and 725 may further include bottom portions 715c and 725c, respectively. The bottom portions 715c and 725c support the first spacers 715a and 725a and the second spacers 715b and 725b. For example, the bottom portions 715c and 725c may be disposed above or below the first spacers 715a and 725a and the second spacers 715b and 725b. That is, the bottom portions 715c and 725c may be disposed between the first spacers 715a and 725a and the second spacers 715b and 725b and the barrier film 600 in the third direction DR3, or between the first spacers 715a and 725a and the second spacers 715b and 725b and the lower visibility preventing member LPU in the third direction DR3. In some embodiments, the bottom portions 715c, 725c may be integral and physically connected to the first spacers 715a, 725a and second spacers 715b, 725b.

[0144] By disposing the bottom portions 715c and 725c, grooves GRV may be disposed between the first spacers 715a and 725a and the second spacers 715b and 725b spaced apart from each other, instead of holes HOL.

[0145] The display device 10 according to this embodiment includes bottom portions 715c and 725c that support the first spacers 715a and 725a and the second spacers 715b and 725b, thereby improving the durability of the first differential pattern 715 and the second differential pattern 725. For example, in addition to the effect obtained in FIG. 9 described above, the effect of connecting the first spacers 715a and 725a and the second spacers 715b and 725b via the bottom portions 715c and 725c can be obtained. For example, because the first spacers 715a and 725a and the second spacers 715b and 725b are both connected to the bottom portions 715c and 725c, an impact applied to the top of the display device 10 can be dispersed to the first spacers 715a and 725a, and an impact transmitted via the bottom portions 715c and 725c can be dispersed by the second spacers 715b and 725b.

[0146] Fig. 12 is a cross-sectional view showing a portion of a display device according to yet another embodiment. Fig. 13 is a plan view showing a panel support member according to the embodiment of Fig. 12. Fig. 12 is a view seen from a first direction DR1, and Fig. 13 is a view seen from a third direction DR3.

[0147] 12 and 13, the display device 10 according to this embodiment differs from the display device 10 according to the embodiment described above with reference to, for example, FIGS. 7 and 10, which include a horizontal differential pattern, in that the differential pattern 730 is a vertical pattern.

[0148] More specifically, the panel support member 700 of the display device 10 according to this embodiment may include a first support 710, a second support 720, and a differential pattern 730. The first support 710 may be disposed in a first non-folding area NFA1, the second support 720 may be disposed in a second non-folding area NFA2, and the differential pattern 730 may be disposed in a folding area FDA. The first support 710, the second support 720, and the differential pattern 730 may be spaced apart from each other in a second direction DR2.

[0149] The first support 710 and the second support 720 may be portions that are not folded when the display device 10 is folded. The first support 710 and the second support 720 may have a plate-like shape. For example, the first support 710 and the second support 720 may have a rectangular shape as shown in FIG.

[0150] The differential pattern 730 may be a portion that is folded when the display device 10 is folded. The differential pattern 730 may include a plurality of bars. The plurality of bars of the differential pattern 730 may extend in the first direction DR1 and the third direction DR3, respectively. The plurality of bars of the differential pattern 730 may have a shape (e.g., a rectangular parallelepiped shape) that extends in the first direction DR1 and has a height in the third direction DR3.

[0151] The bars of the differential pattern 730 may be spaced apart from one another in the second direction DR2. Holes HOL may be arranged between the bars of the differential pattern 730. When the display device 10 is folded, the distance between the bars increases, and the differential pattern 730 is stretched in the second direction DR2, thereby minimizing folding stress.

[0152] The multiple bars of the differential pattern 730 may include first spacers 730a and second spacers 730b. The first spacers 730a and second spacers 730b may be alternately arranged in the second direction DR2. The first spacers 730a and second spacers 730b may have different heights. For example, the height H3 of the first spacer 730a may be greater than the height H4 of the second spacer 730b. The different heights of the first spacers 730a and second spacers 730b may be formed by half-etching or photolithography.

[0153] The bars of the differential pattern 730 may be formed by patterning the panel support member 700. For example, the bars of the differential pattern 730 may be formed by etching a portion of the panel support member 700. Prior to forming the bars of the differential pattern 730, the first support 710, the second support 720, and the differential pattern 730 may be integrated. First spacers 730a, second spacers 730b, and holes HOL may be formed in the integrated differential pattern 730 by half-etching or photolithography. In this case, although not shown in the drawings, bridges connecting the first support 710 and the second support 720 in the second direction DR2 may be disposed on both ends of the differential pattern 730 in the first direction DR1. Because the bars are connected to the bridges, the first support 710, the second support 720, and the bars of the differential pattern 730 may be treated as a single unit while being connected to one another. In this state, the panel support member 700 can be placed on the adhesive barrier film 600 or the lower visibility preventing member LPU to fix the positions of the multiple bars and holes HOL. The bridge is then removed, and the differential pattern 730 can maintain the shape shown in FIG. 13. Therefore, one end of the differential pattern 730 in the first direction DR1 is positioned a first width Lw inward from one end of the first direction DR1 of the first support 710 and / or the second support 720. That is, one end of the first direction DR1 of the first support 710 and / or the second support 720 can protrude a first width Lw from one end of the differential pattern 730 in the first direction DR1.

[0154] Although the drawings show that the first spacers 730a and the second spacers 730b are alternately arranged, this is not limiting. As with the display device 10 according to an embodiment described with reference to FIG. 7, the arrangement of the first spacers 715a, 725a and the second spacers 715b, 725b may be irregular. The number and arrangement order of the first spacers 715a, 725a and the second spacers 715b, 725b are not limited to those shown in the drawings.

[0155] 12, the upper surface of the first spacer 730a may be in direct contact with the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surface of the first spacer 730a may be in direct contact with the upper surface of the lower view preventing member LPU. The upper surface of the second spacer 730b may be spaced apart from the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surface of the second spacer 730b may be in direct contact with the upper surface of the lower view preventing member LPU. In other embodiments, the upper surface of the second spacer 730b may be in direct contact with the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surface of the second spacer 730b may be spaced apart from the upper surface of the lower view preventing member LPU.

[0156] The display device 10 according to this embodiment may have enhanced impact resistance because the differential pattern 730 includes first spacers 730a and second spacers 730b having different heights. For example, as described above, the support layer 610 and adhesive layers 620 and 630 of the barrier film 600 are disposed across the folding region FDA and the non-folding regions NFA1 and NFA2, thereby enhancing the impact resistance of the display device 10. Furthermore, when an impact is applied to the top of the display device 10, a portion of the barrier film 600 is supported by the first spacer 730a to disperse the impact, and another portion of the barrier film 600 is further disperse the impact due to an air gap between the second spacer 730b and the barrier film 600. Furthermore, air can freely circulate through the holes HOL between the first spacers 730a and the second spacers 730b, further improving the cushioning effect of the air gap. Other advantages described in the above embodiments may also be achieved.

[0157] In addition, the display device 10 according to this embodiment can further minimize folding stress by including a hole HOL and a plurality of bars in the differential pattern 730 extending in the first direction DR1, i.e., by including a vertical pattern.

[0158] Fig. 14 is a cross-sectional view showing a portion of a display device according to yet another embodiment. Fig. 15 is a cross-sectional view showing the display device according to the embodiment of Fig. 14. Fig. 14 is a view seen from a first direction DR1, and Fig. 15 is a view seen from a second direction DR2.

[0159] 14 and 15, the display device 10 according to this embodiment differs from the display device 10 according to the embodiments described above with reference to, for example, Figures 7, 10, and 12 in that it further includes a buffer layer EPX. Hereinafter, a case where the differential pattern is a horizontal pattern as in the display device 10 according to one embodiment described with reference to, for example, Figure 7 will be described as an example, but the following content can also be applied to a case where the differential pattern is a vertical pattern as in the display device 10 according to another embodiment described with reference to, for example, Figure 12.

[0160] More specifically, the display device 10 according to the present embodiment may further include a buffer layer EPX.

[0161] The buffer layer EPX is disposed on top of the first differential pattern 715 and the second differential pattern 725. For example, the buffer layer EPX may be disposed between the first differential pattern 715 and the second differential pattern 725 and the barrier film 600 in the third direction DR3.

[0162] The buffer layer EPX is disposed in the second direction DR2 between the first body of the first support 710 and the second body of the second support 720. One side of the buffer layer EPX in the second direction DR2 may be in direct contact with one side of the first support 710 in the second direction DR2, and the other side of the buffer layer EPX in the second direction DR2 may be in direct contact with one side of the second support 720 in the second direction DR2.

[0163] The buffer layer EPX may be an elastomer having elasticity, for example, but not limited to, an epoxy-based elastomer.

[0164] 15, the upper surface of the first spacer 715a may be in direct contact with the lower surface of the buffer layer EPX, and the lower surface of the first spacer 715a may be in direct contact with the upper surface of the lower view preventing member LPU. The upper surface of the second spacer 715b may be spaced apart from the lower surface of the buffer layer EPX, and the lower surface of the second spacer 715b may be in direct contact with the upper surface of the lower view preventing member LPU. In other embodiments, the upper surface of the second spacer 715b may be in direct contact with the lower surface of the buffer layer EPX, and the lower surface of the second spacer 715b may be spaced apart from the upper surface of the lower view preventing member LPU.

[0165] The display device 10 according to this embodiment further includes a buffer layer EPX, which can improve the impact resistance of the display device 10 and the durability of the differential pattern. In addition, the effects described in the above-mentioned embodiments can also be obtained.

[0166] Fig. 16 is a cross-sectional view showing a portion of a display device according to yet another embodiment. Fig. 17 is a cross-sectional view showing the display device according to the embodiment of Fig. 16. Fig. 16 is a view seen from a first direction DR1, and Fig. 17 is a view seen from a second direction DR2.

[0167] 16 and 17, the display device 10 according to this embodiment differs from the display device 10 according to another embodiment described with reference to Fig. 14, etc., in that the buffer layer EPX is disposed below the differential pattern. Hereinafter, a case where the differential pattern is a horizontal pattern as in the display device 10 according to the embodiment described with reference to Fig. 7, etc. will be described as an example, but the following content can also be applied to a case where the differential pattern is a vertical pattern as in the display device 10 according to another embodiment described with reference to Fig. 12, etc.

[0168] More specifically, the buffer layer EPX of the display device 10 according to this embodiment may be disposed below the first differential pattern 715 and the second differential pattern 725. For example, the buffer layer EPX may be disposed between the first differential pattern 715 and the second differential pattern 725 and the lower view prevention member LPU in the third direction DR3.

[0169] 17, the upper surface of the first spacer 715a may be in direct contact with the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surface of the first spacer 715a may be in direct contact with the upper surface of the buffer layer EPX. The upper surface of the second spacer 715b may be in direct contact with the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surface of the second spacer 715b may be spaced apart from the upper surface of the buffer layer EPX. In other embodiments, the upper surface of the second spacer 715b may be spaced apart from the lower surface of the barrier film 600 (e.g., the second adhesive layer 630), and the lower surface of the second spacer 715b may be in direct contact with the upper surface of the buffer layer EPX.

[0170] The display device 10 according to this embodiment further includes a buffer layer EPX, which can improve the impact resistance of the display device 10 and the durability of the differential pattern. In addition, the effects described in the above-mentioned embodiments can also be obtained.

[0171] 18 is a cross-sectional view showing a part of a display device according to yet another embodiment, as viewed from a first direction DR1.

[0172] Referring to Figure 18, the display device 10 according to this embodiment differs from the display device 10 according to the embodiment described above with reference to Figures 14 and 16, etc., in that the buffer layer EPX and the first support 710 and second support 720 are spaced apart from each other.

[0173] More specifically, the buffer layer EPX of the display device 10 according to this embodiment may be disposed between the first body of the first support 710 and the second body of the second support 720 in the second direction DR2.

[0174] A side of the buffer layer EPX is spaced apart from at least one of a side of the first support 710 and a side of the second support 720. For example, one side of the buffer layer EPX in the second direction DR2 may be spaced apart from one side of the first support 710 in the second direction DR2, and the other side of the buffer layer EPX in the second direction DR2 may be spaced apart from one side of the second support 720 in the second direction DR2.

[0175] As another example, one side of the buffer layer EPX in the second direction DR2 may be in direct contact with one side of the first support 710 in the second direction DR2, and the other side of the buffer layer EPX in the second direction DR2 may be spaced apart from one side of the second support 720 in the second direction DR2. As yet another example, one side of the buffer layer EPX in the second direction DR2 may be spaced apart from one side of the first support 710 in the second direction DR2, and the other side of the buffer layer EPX in the second direction DR2 may be in direct contact with one side of the second support 720 in the second direction DR2.

[0176] According to the display device 10 of this embodiment, when the buffer layer EPX and the panel support member 700 are joined together, an attachment tolerance can be ensured corresponding to the distances between the buffer layer EPX and the first support 710 and the second support 720. In addition, the effects described in the above-described embodiments can also be obtained.

[0177] 19 is a cross-sectional view showing a part of a display device according to yet another embodiment, as viewed from a first direction DR1.

[0178] Referring to FIG. 19, the display device 10 according to this embodiment differs from the display device 10 according to the embodiment described above with reference to FIGS. 14, 16, 18, etc. in that the upper surface of the buffer layer EPX protrudes.

[0179] More specifically, the upper surface of the buffer layer EPX of the display device 10 according to this embodiment may protrude from the upper surfaces of the first support 710 and the second support 720. For example, the upper surface of the buffer layer EPX may protrude from the upper surfaces of the first support 710 and the second support 720 in the third direction DR3, for example, upward, by a first height Ly.

[0180] The barrier film 600 may have a conformal shape along the upper surfaces of the first support 710, the buffer layer EPX, and the second support 720, for example, a tightly adhered shape along the upper surfaces of the first support 710, the buffer layer EPX, and the second support 720. For example, the barrier film 600 may have a shape that protrudes in the third direction DR3 in the folding region FDA. The barrier film 600 may contact not only the upper surface of the buffer layer EPX but also a portion of the side surface of the buffer layer EPX.

[0181] As the thickness of the buffer layer EPX of the display device 10 according to this embodiment increases, the buffering effect increases, and the occurrence of creases caused by bending of the upper member in the folding region FDA when the display device 10 is folded can be minimized. For example, the thicker the buffer layer EPX, the greater the effect of cushioning the impact applied to the display device 10. Furthermore, even if the buffer layer EPX is thick, the barrier film 600 provides a conformal shape along the upper surfaces of the first support 710, the buffer layer EPX, and the second support 720, thereby suppressing the occurrence of creases caused by bending of the upper member in the folding region FDA when the display device 10 is folded. Other effects described in the above-described embodiments can also be obtained.

[0182] Fig. 20 is a cross-sectional view showing a part of a display device according to still another embodiment. Fig. 21 is a cross-sectional view showing a part of a display device according to still another embodiment. Figs. 20 and 21 are views seen from a first direction DR1.

[0183] Referring to Figures 20 and 21, the display device 10 according to this embodiment differs from the display device 10 according to an embodiment described with reference to Figures 7, 10, 12, 14, 16, 18, and 19, etc., in that the positions of the buffer layer EPX and the barrier film 600 are different.

[0184] More specifically, the panel support member 700 may include a first support 710 and a second support 720. Unlike the previously described embodiments, the panel support member 700 may not include a differential pattern between the first support 710 and the second support 720.

[0185] The barrier film 600 is disposed between the first support 710 and the second support 720. For example, the barrier film 600 may be disposed between the first support 710 and the second support 720 in the second direction DR2. The barrier film 600 may be disposed in the folding region FDA.

[0186] The lower visibility preventing member LPU is disposed at the lower part of the panel support member 700. The upper surface of the lower visibility preventing member LPU may be in direct contact with the lower surface of the barrier film 600 (e.g., the lower surface of the second adhesive layer 630). The width LPU_L of the lower visibility preventing member LPU may be larger than the width of the barrier film 600 in the second direction DR2.

[0187] The buffer layer EPX is disposed on the panel support member 700. In some embodiments, as shown in FIG. 20 , the buffer layer EPX is disposed on the top of the panel support member 700. More specifically, in the example of FIG. 20 , the buffer layer EPX is disposed on the top of the panel support member 700 and on the top of the barrier film 600. For example, the buffer layer EPX may be disposed on the top surface of the panel support member 700. More specifically, in the example of FIG. 20 , the buffer layer EPX is disposed on the top surface of the panel support member 700 and on the top surface of the barrier film 600. In other embodiments, as shown in FIG. 21 , the buffer layer EPX may be disposed on the bottom of the panel support member 700. More specifically, in the example of FIG. 21 , the buffer layer EPX is disposed on the bottom of the panel support member 700 and on the bottom of the barrier film 600. For example, the buffer layer EPX may be disposed on the bottom surface of the panel support member 700. More specifically, in the example of FIG. 21 , the buffer layer EPX is disposed on the bottom surface of the panel support member 700 and on the bottom surface of the barrier film 600. The buffer layer EPX may be disposed across the folded region FDA and the non-folded regions NFA1 and NFA2.

[0188] The lower surface (or upper surface) of the buffer layer EPX can be in direct contact with the upper surface (or lower surface) of the barrier film 600. This can minimize the folding stress of the barrier film 600 in the folding region FDA.

[0189] In the display device 10 according to this embodiment, instead of a differential pattern, a barrier film 600 is disposed between the first support 710 and the second support 720 to increase the durability of the folding area FDA, and a buffer layer EPX is disposed on the panel support member 700 to minimize folding stress and enhance impact resistance.

[0190] The display device 10 according to the above-described embodiment can be applied to various electronic devices. An electronic device according to an embodiment may include the above-described display device 10, and may further include a module or device having additional functions other than the display device 10. In some embodiments, the electronic device may be a foldable display device 1.

[0191] FIG. 22 is an exploded perspective view of a foldable display device according to an embodiment.

[0192] 22, the foldable display device 1 includes a display device 10 and a folding member FDM. The folding member FDM includes a first support member 11, a second support member 12, a hinge 13, a hinge cover 14, a first back cover 15, and a second back cover 16.

[0193] The first and second support members 11 and 12 are arranged in a first direction DR1, and the display device 10 is disposed on the first and second support members 11 and 12 and the hinge 13.

[0194] One side of the first support member 11 and one side of the second support member 12 are arranged to face each other. The folding area FDA of the display device 10 is arranged on the joining position of the first and second support members 11 and 12 and the hinge 13, and the non-folding areas NFA1 and NFA2 of the display panel are arranged on the upper surfaces of the first and second support members, respectively.

[0195] The hinge 13 is connected to one side of the first support member 11 and one side of the second support member 12, which face each other in the first direction DR1. The hinge 13 has a rotation shaft on one side of the first support member 11 and one side of the second support member 12. The rotation shafts include a first rotation shaft provided on one side of the first support member 11 and a second rotation shaft provided on one side of the second support member 12.

[0196] The first rear cover 15 is disposed on the rear surface of the first support member 11 to cover the first support member 11. The first rear cover 15 may be disposed to cover a portion of the hinge cover 14 disposed between the first support member 11 and the second support member 12 (e.g., the upper end of the lower surface of the hinge cover). The first rear cover 15 may have rounded corners. The first rear cover 15 may be hollow, or may be fastened to the first support member 11 to form an empty space between the first support member 11 and the first rear cover 15. For example, the first rear cover 15 may have a rectangular bottom surface and three side walls extending from the bottom surface. That is, one side of the rectangle may be open without a side wall.

[0197] The second rear cover 16 is disposed on the rear surface of the second support member 12 to cover the second support member 12. The second rear cover 16 may be disposed to cover the remaining portion of the hinge cover 14 (e.g., the lower end of the hinge cover) that is partially covered by the second rear cover 16. The second rear cover 16 may have rounded corners, similar to the first rear cover 15. The second rear cover 16 may be hollow or may be fastened to the second support member 12 to form an empty space between the second support member 12. In this regard, the second rear cover 16 may have a structure in which a rectangular bottom surface and three side walls extending from the bottom surface are formed. In other words, one side of the rectangle may be open without a side wall.

[0198] The hinge 13 is placed on and fixed to the hinge cover 14. The hinge cover 14 is covered by one side of the first rear cover 15 and the second rear cover 16 or exposed to the outside depending on the folding state of the foldable display device 1. For example, when the foldable display device 1 is unfolded, the hinge cover 14 is covered by the first rear cover 15 and the second rear cover 16. When the foldable display device 1 is folded, the hinge cover 14 may be arranged to be exposed to the outside from the sides of the first rear cover 15 and the second rear cover 16.

[0199] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the above embodiments are illustrative in all respects and are not limiting. [Explanation of symbols]
