[0061] Hereinafter, a display device according to some exemplary embodiments of the present disclosure will be described.

[0062] Hereinafter, a display device of the present disclosure will be described through drawings and exemplary embodiments.

The display device 100 may also include a resin layer 90 (see Figure 6 ).

[0064] The display panel 110 may include a display area AA displaying an image and a non-display area NA, which is an area other than the display area AA. The non-display area NA is configured to be near, partially or completely surround the display area AA.

The driver may be a gate in panel (GIP) or a driver integrated circuit (D-IC). The display panel 110 may include a bending area BA (see Figure 4 ), which is bent at one side of the front surface of the display panel 110 in the non-display area NA. One side of the front surface of the non-display area NA of the display panel 110 is bent by the bending area BA so that the rear surface of the display panel 110 and the rear surface of the non-display area NA of the display panel 110 can face each other.

[0066] The non-display area NA may be an area having the bending area BA on one side of the display panel 110 and overlapping the bezel area BZ of the display device 100. The bezel area BZ may be provided on four sides of the display panel 110. The bezel area BZ may include a partial bezel area located on one side of the display panel 110 overlapping the bending area BA and partial bezel areas located on the remaining three sides of the display panel 110 that do not overlap the bending area BA or overlap the non-display area NA that does not define the bending area BA. The non-display area NA adjacent to the bending area BA may be connected to the driving film 113.

[0067] The driving film 113 is disposed on the rear surface of the display panel 110. The driving film 113 may have a plurality of wirings (not shown) for driving the display panel 110, and may have at least one driver circuit chip (not shown). Terminals disposed on a predetermined side of the driving film 113 may be connected to a printed circuit board (not shown) or a flexible circuit board (not shown) through a film attachment process.

[0068] A shielding member 119 covering at least a portion of the driving film 113 may be further disposed on the rear surface of the display panel 110 .

[0069] The shielding member 119 may be provided to cover a printed circuit board (not shown) connected to the driving film 113, protect a driver circuit chip (not shown) provided between the rear surface of the display panel 110 and the driving film 113, and perform an electrostatic discharge (ESD) function on components adjacent thereto. For example, the driver circuit chip may include a data driver circuit and a gate driver circuit, and may further include a controller for controlling the data driver circuit and the gate driver circuit.

[0070] A plurality of sub-pixels SP may be arranged in the display area AA of the display panel 110 , and an image may be displayed using the plurality of sub-pixels SP.

[0071] Reference Figure 3 , at least one sub-pixel SP in the plurality of pixels may include a switching transistor SW, a driving transistor DR, a capacitor Cst, a compensation circuit CC, and an organic light emitting diode OLED. However, the present disclosure is not limited thereto. For example, the number of transistors TFT in the pixel circuit of the present disclosure may be two or more, and the number of capacitors may be one or more.

[0072] The active layer or semiconductor layer of the transistor TFT may be formed of a semiconductor material, such as an oxide semiconductor, an amorphous semiconductor, or a polycrystalline semiconductor, but is not limited thereto.

[0073] Oxide semiconductor materials can have excellent effects of preventing leakage current and relatively cheap manufacturing costs. Oxide semiconductors can be made of metal oxides such as zinc (Zn), indium (In), gallium (Ga), tin (Sn) and titanium (Ti) or metals such as zinc (Zn), indium (In), gallium (Ga), tin (Sn) or titanium (Ti) and combinations of their oxides. Specifically, oxide semiconductors can include zinc oxide (ZnO), zinc tin oxide (ZTO), zinc indium oxide (ZIO), indium oxide (InO), titanium oxide (TiO), indium gallium zinc oxide (IGZO), indium zinc tin oxide (IZTO), indium zinc oxide (IZO), indium gallium tin oxide (IGTO) and indium gallium oxide (IGO), but are not limited thereto.

[0074] The polycrystalline semiconductor material has a fast moving speed of carriers such as electrons and holes, and thus has high mobility, and has low power consumption and excellent reliability. The polycrystalline semiconductor may be made of polycrystalline silicon (poly-Si), but is not limited thereto.

[0075] The amorphous semiconductor material may be made of amorphous silicon (a-Si), but is not limited thereto.

[0076] Reference Figure 3 , a first electrode (e.g., a drain electrode) of the switching transistor SW is electrically connected to the data line DL, and a second electrode (e.g., a source electrode) is electrically connected to the first node N1. A gate electrode of the switching transistor SW is electrically connected to the gate line GL. The switching transistor SW transmits a data signal supplied via the data line DL to the first node N1 in response to a scan signal supplied via the gate line GL.

[0077] The capacitor Cst is electrically connected to the first node N1 and charges a voltage applied to the first node N1.

[0078] A first electrode (e.g., drain electrode) of the driving transistor DR is applied with a high potential driving voltage EVDD, and a second electrode (e.g., source electrode) is electrically connected to a first electrode (e.g., anode electrode) of the organic light emitting diode OLED. The driving transistor DR can control the amount of driving current flowing through the organic light emitting diode OLED in response to a voltage applied to its gate electrode.

[0079] The semiconductor layer of the switching transistor SW and / or the driving transistor DR may include silicon such as amorphous silicon (a-Si), polycrystalline silicon (poly-Si), or low-temperature polycrystalline silicon (poly-Si), or an oxide such as indium gallium zinc oxide (IGZO), but the present disclosure may not be limited thereto.

[0080] The organic light emitting diode OLED outputs light corresponding to the driving current. The organic light emitting diode OLED may output light having a color corresponding to one of red, green, blue, and white.

[0081] The organic light emitting diode OLED may include an anode electrode, a light emitting layer disposed on the anode electrode, and a cathode electrode for supplying a common voltage. The light emitting layer may be implemented to emit light of the same color, such as white light, for each pixel, or may be implemented to emit light of different colors, such as red light, green light, or blue light, for each sub-pixel SP. The sub-pixel SP is the smallest unit constituting the display area, and n sub-pixels SP form one pixel. Each of the plurality of sub-pixels SP may emit light having wavelengths different from each other. The plurality of sub-pixels may include a first sub-pixel, a second sub-pixel, and a third sub-pixel that emit light of different colors from each other. For example, the plurality of sub-pixels SP may include a red sub-pixel SP, a green sub-pixel SP, and a blue sub-pixel SP. According to the present exemplary embodiment, at least some of the plurality of pixels may also include a white sub-pixel SP. The plurality of sub-pixels SP may be variously modified in color and configuration as needed. However, the present disclosure is not limited thereto.

[0082] For example, a plurality of sub-pixels SP may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, wherein the red sub-pixel, the green sub-pixel, and the blue sub-pixel may be arranged in a repeated manner. Alternatively, a plurality of sub-pixels SP may include a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, wherein the red sub-pixel, the green sub-pixel, the blue sub-pixel, and the white sub-pixel may be arranged in a repeated manner, or the red sub-pixel, the green sub-pixel, the blue sub-pixel, and the white sub-pixel may be arranged in a quadrilateral type. For example, the red sub-pixel, the blue sub-pixel, and the green sub-pixel may be arranged sequentially along the row direction, or the red sub-pixel, the blue sub-pixel, the green sub-pixel, and the white sub-pixel may be arranged sequentially along the row direction. However, in an embodiment of the present disclosure, the color type, arrangement type, and arrangement order of the sub-pixel are not limited, and may be configured in various forms according to the luminous characteristics, device life, and device specifications.

[0083] In addition, the sub-pixels may have different light-emitting areas according to the light-emitting characteristics. For example, a sub-pixel emitting light of a color different from the color of the blue sub-pixel may have a light-emitting area different from the light-emitting area of ​​the blue sub-pixel. For example, a red sub-pixel, a blue sub-pixel, and a green sub-pixel, or a red sub-pixel, a blue sub-pixel, a white sub-pixel, and a green sub-pixel may each have a different light-emitting area.

[0084] The compensation circuit CC may be provided in the sub-pixel SP to compensate for the threshold voltage of the driving transistor DR, etc. The compensation circuit CC may be composed of one or more transistors and provided between the gate of the driving transistor DR and the capacitor Cst. The compensation circuit CC may include one or more transistors and capacitors, and may be constructed in various ways according to the compensation method. The pixel including the compensation circuit CC may have various structures such as 3T1C, 4T2C, 5T2C, 6T1C, 6T2C, 7T1C, 7T2C, etc.

[0085] like Figure 4 As shown, the display panel 110 may include a display substrate 111 and an encapsulation portion 112 , and the display substrate 111 includes a pixel array having a plurality of sub-pixels SP.

[0086] The display substrate 111 provided with the sub-pixel SP may be made of a flexible plastic material and have a flexible property. For example, the display substrate 111 may be formed to include polyimide and may include a thin glass material having flexibility. In addition, in some exemplary embodiments, the display substrate 111 may be made of a flexible polymer film. For example, the flexible polymer film may be made of any one of polyimide (PI), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polycarbonate (PC), polyether sulfone (PES), polyarylate (PAR), polysulfone (PSF), cyclic olefin copolymer (COC), triacetyl cellulose (TAC), polyvinyl alcohol (PVA) and polystyrene (PS), and the present disclosure is not limited thereto.

[0087] A pixel array constituting a plurality of sub-pixels SP may be disposed on the display substrate 111. The portion where the pixel array constituting the plurality of sub-pixels SP is disposed may be the display area AA. Figure 1 Therefore, a region corresponding to the pixel array in which the plurality of sub-pixels SP are arranged may become a display region AA, and a region other than the display region AA may become a non-display region NA.

[0088] The encapsulation portion 112 may be disposed on the display substrate 111 to cover a plurality of sub-pixels SP. The encapsulation portion 112 may prevent oxygen, moisture, or foreign matter from penetrating into the plurality of sub-pixels SP. The encapsulation portion 112 may be formed as a multilayer structure in which organic material layers and inorganic material layers are alternately stacked, but the present disclosure may not be limited thereto. For example, the encapsulation portion 112 may have a multi-insulating film structure in which organic films and inorganic films are alternately stacked. The inorganic film blocks the penetration of oxygen, moisture, or foreign matter. The organic film planarizes the surface of the inorganic film. When the organic film and the inorganic film are stacked in multiple layers, the movement path of oxygen, moisture, or foreign matter is longer than that of a single layer, so that the penetration of oxygen, moisture, or foreign matter that affects the light-emitting device layer can be effectively blocked.

[0099] In the bending area BA, in order to increase the flexibility of the display panel 110, other components except the display substrate 111 and the signal wiring may be removed, so the rigidity may be reduced, and the coating layer 158 may supplement the rigidity of the bending area BA with the removal of other components.

[0100] The coating 158 may be referred to as a micro coating (MLC).

[0110] The optical bonding member 190 may be used to attach the display panel 110 to the cover member 20. Since the optical bonding member 190 may overlap the display area AA, a material that may transmit an image of the display panel 110 may be used. For example, the optical bonding member 190 may be made of or include a material such as an optically clear adhesive (OCA), an optically clear resin (OCR), or a pressure sensitive adhesive (PSA), but the present disclosure may not be limited thereto.

[0111] The display device 100 includes a back plate 220 disposed below the display panel 110. The back plate 220 is disposed on the rear surface of the display panel 110 so that the lower side of the display panel 110 maintains a flat surface or a flat state and the display substrate 111 is supported. The back plate 220 may be attached to the display panel 110 or a structure of the rear surface of the display panel 110 via the adhesive member 210.

For example, the first back plate 221 and the second back plate 222 may be made of different materials and / or have different thicknesses.

[0116] The back plate 220 may not be formed in the bending area BA where the display panel 110 is bent, or may be disposed to overlap a portion of a starting portion or an ending portion of the bending area BA.

[0117] The back plate 220 may be formed to have a certain strength and thickness to supplement the rigidity of the display substrate 111. The back plate 220 may be made of a rigid plastic film.

[0126] The protective film 170 is disposed in the partial bezel region BZ having the curved area BA of the display device 100. The protective film 170 may be disposed to overlap the coating layer 158. In the partial bezel region BZ having the curved area BA of the display device 100, the protective film 170 may be disposed in a structure surrounding the curved area BA.

[0127] The protection film 170 may be disposed to overlap at least a portion of the cover member 20 in the partial bezel area BZ of the display device 100 having the bent area BA and cover at least a portion of the side surface of the edge of the coating layer 158 and the back plate 220 .

[0128] The protective film 170 may be Figure 4 As shown in FIG. 1 , the resin layer 90 is disposed in a partial frame region BZ of the curved region BA where the display panel 110 is disposed, and the resin layer 90 may be as shown in FIG. Figure 6 The arrangement shown is in the remaining three partial border areas BZ where the bending area BA is not arranged.

[0129] The thickness of the protective film 170 disposed in one partial bezel region BZ having the bent area BA of the display panel 110 may be smaller than the thickness of the resin layer 90 disposed in the remaining three partial bezel regions BZ having no bent area BA.

[0130] In this regard, an air gap between the display panel 110 and other components may be minimized and a thin bezel may be achieved by placing a protective film 170 thinner than the resin layer 90 in a partial bezel region BZ having a bent region BA in which the width and thickness of the bezel region BZ may be relatively increased.

[0131] Since the protective film 170 has a smaller thickness than the resin layer 90 , it is possible to completely fill the display panel 110 or / and the space between the optical plate 180 and the cover member 20 without generating an uncoated area.

[0132] Specifically, in the partial bezel area BZ having the curved area BA, the cover member 20 and the coating 158 may be disposed to be spaced apart from each other. The protective film 170 may be disposed to overlap at least a portion of the rear surface of the cover member 20 within a space defined as a space where the rear surface of the cover member 20 and the top surface of the coating 158 are spaced apart from each other, and may be disposed to overlap the entire top surface of the coating 158.

[0133] The optical bonding member 190 disposed between the cover member 20 and the display panel 110 and the optical plate 180 disposed between the optical bonding member 190 and the display panel 110 and protruding further toward the bending area BA than the optical bonding member 190 may be disposed in a space defined by the cover member 20 and the coating layer 158 being spaced apart from each other. The protective film 170 may be disposed to cover a side surface of the optical bonding member 190 perpendicular to the top surface of the display panel 110 in the non-display area NA adjacent to the bending area BA, a side surface of the optical plate 180 perpendicular to the top surface of the display panel 110, and a protruding top surface of the optical plate 180.

[0134] The protection film 170 may be disposed to cover the light blocking pattern 22 disposed adjacent to the bending area BA.

[0135] like Figure 5 As shown, the protective film 170 can be set to surround the side surfaces of the edge of the first back plate 221 adjacent to the bending area BA and the side surfaces of the edge of the first adhesive layer 211, as well as the side surfaces of the edge of the second back plate 222 adjacent to the bending area BA and the side surfaces of the edge of the second adhesive layer 212.

[0136] The protection film 170 may be disposed to overlap side and top surfaces of an edge of the coating layer 158 disposed to cover the bending area BA and extend to the non-display area NA adjacent to the bending area BA to overlap at least a portion of the back plate 220 .

[0137] The protective film 170 can be configured to cover the side surfaces of the coating 158 and the edge of the display panel 110 in the bending area BA, and to cover the side surfaces of the coating 158, the edge of the display panel 110 and at least a portion of the edge of the back panel 220 in the non-display area NA adjacent to the bending area BA.

[0138] The protective film 170 may be disposed to cover the side surface of the edge of the pad layer 219 in the non-display area NA. The protective film 170 may be disposed to at least partially cover the side surface of the edge of the first adhesive layer 211, the side surface of the edge of the second adhesive layer 212, the side surface of the edge of the third adhesive layer 213, and the side surface of the edge of the fourth adhesive layer 214 in the non-display area NA.

[0139] The first adhesive layer 211, the second adhesive layer 212, the third adhesive layer 213 and the fourth adhesive layer 214 can be double-sided adhesive tapes with adhesiveness. The first adhesive layer 211, the second adhesive layer 212, the third adhesive layer 213 and the fourth adhesive layer 214 can contain adhesive materials, and the adhesive materials can be thermally cured or naturally cured adhesives. The first adhesive layer 211, the second adhesive layer 212, the third adhesive layer 213 and the fourth adhesive layer 214 can be made of materials such as pressure sensitive adhesives (PSA).

[0140] By placing the protective film 170 on the partial bezel area BZ having the bent area BA, the display device 100 can be prevented from being damaged by external impact, etc., and the reliability of the display device 100 can be improved by preventing metal corrosion and blocking gas, moisture, etc.

[0141] The protective film 170 may be made of a material different from that of the resin layer 90. The protective film 170 may be made of a material that is a film containing an organic material but does not contain isobornyl acrylate (IBOA). The protective film 170 may contain a polyparaxylene-based organic material. As the protective film 170, a polyparaxylene C-based material may be used. Using a polyparaxylene-based material as the protective film 170, the protective film 170 may have a constant thickness in the frame area BZ and minimize thermal deformation.

[0142] The protective film 170 according to the exemplary embodiment of the present disclosure may have excellent gas barrier properties, excellent resistance to solvents such as acids and alkalis, minimize or reduce outgassing occurring inside, and have excellent water vapor transmission rate (WVTR). Therefore, the protective film 170 may be disposed in a partial bezel region BZ including the bending region BA where there is a relatively complex arrangement and driving components may be closely disposed, thereby improving the reliability of the display device 100.

[0143] The protective film 170 is formed of a material that does not contain isobornyl acrylate (IBOA), thereby preventing harmful effects on a human body and realizing an environmentally friendly product.

[0144] Reference Figure 6 , the resin layer 90 may be disposed in a partial bezel region BZ of the display panel 110 where the display panel 110 is not bent. Specifically, the resin layer 90 may be disposed on three sides of the display panel 110 except for one side of the display panel 110 having the bent region BA to surround the side surfaces of the display panel 110, the side surfaces of the back plates 220 and 221, and at least a portion of the rear surface of the cover member 20, and include a material different from that of the protective film 170. For example, the protective film 170 may be formed as follows: Figure 4 As shown, the resin layer 90 is disposed on the side of the display panel 110 where the bending area BA is disposed, and the resin layer 90 may be as shown. Figure 6The protective film 170 is disposed on three sides of the display panel 110 except for one side of the display panel 110 having the curved area BA to surround the side surfaces of the display panel 110, the side surfaces of the back plates 220 and 221, and at least a portion of the rear surface of the cover member 20, and includes a material different from that of the protective film 170. However, the present disclosure is not limited thereto.

[0145] The resin layer 90 may be disposed in contact with at least one side surface of the optical bonding member 190, at least one side surface and at least a portion of the top surface of the optical plate 180, one side surface of the curved area BA of the display panel 110 where the display panel 110 is not disposed, and one side surface of the first back plate 221. The resin layer 90 may be in contact with the rear surface of the light blocking pattern 22 disposed on the rear surface of the cover member 20.

[0146] The resin layer 90 may be disposed to fill a space between the cover member 20 and a protruding top surface of the optical plate 180, which is disposed to protrude further toward the bezel area BZ than the optical bonding member 190. The resin layer 90 may be disposed to cover a side surface of the optical bonding member 190 perpendicular to the top surface of the display panel 110, a side surface of the optical plate 180 perpendicular to the top surface of the display panel 110, and a protruding top surface of the optical plate 180 on three sides of the display panel 110 except the bending area BA or a portion of the bezel area BZ.

[0147] The optical plate 180 is disposed between the display panel 110 and the cover member 20 to protrude farther toward the bezel area BZ than the optical bonding member 190, so that a separation space may be defined between the cover member 20 and the display panel 110 or between the cover member 20 and the optical plate 180. In the present disclosure, the space between the cover member 20 and the display panel 110 or between the cover member 20 and the optical plate 180 is covered by the resin layer 90, so that the top and side surfaces of the optical plate 180 and the display panel 110 are not exposed to the outside, thereby preventing foreign matter, moisture, and air from penetrating into the top and side surfaces of the display panel 110.

[0148] The side surface where the above-mentioned resin layer 90 is disposed may include side surfaces of the remaining three sides of the display panel 110 where the bending area BA of the display panel 110 is not disposed.

[0149] As an example, the resin layer 90 may be disposed in the remaining three partial bezel regions BZ of the display panel 110 where the bending region BA of the display panel 110 is not disposed. The resin layer 90 may be disposed around the three partial bezel regions BZ of the display panel 110 where the bending region BA of the display panel 110 is not disposed. Figure 4 The resin layer 90 may be provided to fill a space between the cover member 20 and the bottom member 280 on one side of the display panel 110 or the frame area BZ.

[0150] The resin layer 90 may be disposed in the bezel region BZ of the display device 100 to prevent foreign matter, moisture, etc. from penetrating into the display panel 110 , and may attach and fix the display panel 110 to the cover member 20 .

[0151] The resin layer 90 can attach the covering member 20 and the back panels 220 and 221 to each other between the covering member 20 and the back panels 220 and 221 in a partial border area BZ that does not include the bending area BA, and the resin layer 90 can attach the adhesive member 210, the back panel 220 and the bottom member 280 to each other on one side of the adhesive member 210 to allow the display panel 110 to be firmly connected to the covering member 20 or the bottom member 280, thereby improving the rigidity of the display device 100.

[0152] The resin layer 90 may be an adhesive member such as glue. The resin layer 90 may be a transparent adhesive member. The resin layer 90 may include a resin. For example, the resin layer 90 may include an ultraviolet (UV) curable acrylic resin or a thermosetting resin, but the present disclosure may not be limited thereto.

[0153] In this way, the protective film 170 is arranged in the partial border area BZ of the display device 100 where the curved area BA is provided to cover the periphery of one side surface of the display panel 110, and the resin layer 90 is arranged in the remaining partial border area BZ of the display device 100 where the curved area BA is not provided to cover the periphery of the display panel 110, so that the air gap between the display panel 110 and other components in the partial border area BZ having the curved area BA in which the width and thickness of the border area BZ can be relatively increased can be minimized, thereby realizing a thin border.

[0154] When the resin layer 90 is provided, the resin layer 90 is in a molten state and thus can flow into the interface between the layers of the display panel assembly. For example, when the resin layer 90 is placed in a molten state or the display panel 110 is bonded to the cover member 20, when the protective film 170 is not provided on the bending area BA according to the present disclosure, some charges migrated in the display panel 110 may be introduced into the driving film 113 provided adjacent to the bending area BA, which may cause a charge charging defect in the display panel 110, thereby causing defects such as edge bright spots (EBS).

[0155] The display device 100 according to the present disclosure places the protective film 170 on a portion of the frame area BZ of the display device 100 where the curved area BA of the display panel 110 is provided (the portion of the frame area BZ includes the curved area BA of the display panel 110) to cover a portion adjacent to the curved area BA, thereby preventing charges from migrating toward the display panel 110 or the driving film 113. Therefore, the display device 100 according to the present disclosure can reduce the charge charging defect of the display panel 110, thereby improving the reliability of the display device 100.

[0156] like Figure 6 As shown, the display device 100 may further include a bottom member 280 disposed under the back plates 220 and 221. The bottom member 280 may be coupled with the cover member 20 via the resin layer 90.

[0157] The bottom member 280 accommodates and supports the display panel 110, the structure on the top surface of the display panel 110 (e.g., the optical plate 180), and / or the structure on the rear surface of the display panel 110 (e.g., the back plate 220, etc.). The bottom member 280 may be a heat sink. The bottom member 280 may be used to protect the display panel 110 from external influences while supplementing the rigidity of the display panel 110.

[0158] Although the exemplary embodiments of the present disclosure have been described with reference to the accompanying drawings, the present disclosure is not limited to the exemplary embodiments described above, but can be implemented in various different forms. It will be appreciated by those skilled in the art that the present disclosure can be practiced in other specific forms without changing the technical spirit or basic features of the present disclosure. Therefore, it should be understood that the exemplary embodiments described above are not restrictive, but illustrative in all aspects.
