[0079] FIG. 1 is a perspective view schematically illustrating a display device according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view schematically illustrating an example of the I-I' section of FIG. 1.

[0080] Referring to FIG. 1, a display device (1) according to one embodiment of the present invention may include a display area (DA) and a peripheral area (PA). The peripheral area (PA) is arranged to surround the display area (DA) at the outer edge of the display area (DA). Various wirings and driving circuits that transmit electrical signals to be applied to the display area (DA) may be located in the peripheral area (PA). The display device (1) may provide a predetermined image using light emitted from a plurality of pixels arranged in the display area (DA). Although not illustrated, the display device (1) may be bent to include a bending area in a part of the peripheral area (PA).

[0081] The display device (1) may be a display device such as an organic light-emitting display, an inorganic light-emitting display (or inorganic EL display), or a quantum dot light-emitting display. Below, an organic light-emitting display will be used as an example. The display device (1) can be implemented as various types of electronic devices such as mobile phones, laptops, and smartwatches.

[0082] As illustrated in FIG. 2, the display device (1) may include a display panel (10) stacked sequentially in the thickness direction (z-direction), a protective film layer (20) on the display panel (10), and a polarizing layer (50) on the protective film layer (20). Specifically, the display panel (10) may include a substrate (100) stacked sequentially in the thickness direction (z-direction), a pixel layer (PXL) on the substrate (100), and a sealing member (300) disposed on the pixel layer (PXL) and sealing the pixel layer (PXL). Additionally, the display device (1) may include a first adhesive layer (30) disposed between the sealing member (300) and the protective film layer (20), and a second adhesive layer (40) disposed between the protective film layer (20) and the polarizing layer (50).

[0083] The substrate (100) may include a glass material or a polymer resin. For example, the substrate (100) may include a glass material with SiO2 as the main component, or a resin having various materials with flexible or bendable properties, such as reinforced plastic. Although not illustrated, the substrate (100) may be bent to include a bending region in a portion of the peripheral region (PA).

[0084] A pixel layer (PXL) may be disposed on a substrate (100). The pixel layer (PXL) may include a display element layer (DPL) comprising display elements disposed for each pixel and a pixel circuit layer (PCL) comprising a pixel circuit and insulating layers disposed for each pixel. The display element layer (DPL) is disposed on the upper layer of the pixel circuit layer (PCL), and a plurality of insulating layers may be disposed between the pixel circuit and the display elements. Some of the wiring and insulating layers of the pixel circuit layer (PCL) may extend to a peripheral area (PA).

[0085] The encapsulation member (300) may be a thin film encapsulation layer. The thin film encapsulation layer may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. When a display device (1) is provided with a substrate (100) including a polymer resin and an encapsulation member (300) having a thin film encapsulation layer including an inorganic encapsulation layer and an organic encapsulation layer, the flexibility of the display device (1) can be improved.

[0086] The protective film layer (20) can protect the display device (1). For example, the protective film layer (20) can protect the display device (1) from impacts applied to the display device (1) from the outside.

[0087] The polarization layer (50) transmits only light that vibrates in the same direction as the polarization axis from the light emitted from the display element layer (DPL), and can absorb or reflect light that vibrates in other directions.

[0088] The first adhesive layer (30) is positioned between the encapsulating member (300) and the protective film layer (20) to bond the encapsulating member (300) and the protective film layer (20). Additionally, the second adhesive layer (40) is positioned between the protective film layer (20) and the polarizing layer (50) to bond the protective film layer (20) and the polarizing layer (50).

[0089] FIG. 3 is a plan view schematically illustrating a part of the display device of FIG. 1, and FIG. 4 is a circuit diagram illustrating an example of a pixel of the display device of FIG. 1.

[0090] Referring to FIG. 3, the substrate (100) may include a display area (DA) and a peripheral area (PA). The peripheral area (PA) may be located outside the display area (DA) and surround the display area (DA).

[0091] A plurality of pixels (PX) arranged in a predetermined pattern in a first direction (x direction, row direction) and a second direction (y direction, column direction) may be provided in the display area (DA) on the upper part of the substrate (100).

[0092] In the peripheral area (PA) on the upper part of the substrate (100), a scan driver (GP) that provides a scan signal to each pixel (PX), a data driver (DD) that provides a data signal to each pixel (PX), and main power lines (not shown) for providing a first power supply voltage (ELVDD, see FIG. 4) and a second power supply voltage (ELVSS, see FIG. 4) may be arranged. In the peripheral area (PA) on the upper part of the substrate (100), a pad section (140) in which a plurality of signal pads (SP) connected to a data line (DL) are arranged may be located.

[0093] The scan driver (GP) may include an OSG (Oxide Semiconductor TFT Gate driver circuit) or an ASG (Amorphous Silicon TFT Gate driver circuit). Although FIG. 3 illustrates an example in which the scan driver (GP) is positioned adjacent to one side of the substrate (100), according to the embodiment, the scan driver (GP) may be positioned adjacent to each of the two opposing sides of the substrate (100).

[0094] FIG. 3 illustrates a Chip On Film (COF) method in which a data driver (DD) is placed on a film (OF) electrically connected to signal pads (SP) placed on the upper surface of a substrate (100). According to another embodiment, the data driver (DD) may be placed directly on the upper surface of the substrate (100) in a Chip On Glass (COG) or Chip On Plastic (COP) manner. The data driver (DD) may be electrically connected to a flexible Printed Circuit Board (FPCB).

[0095] Referring to FIG. 4, a pixel (PX) may include a pixel circuit (PC) and an organic light-emitting diode (OLED) electrically connected to the pixel circuit (PC).

[0096] Each pixel (PX) can emit light, for example, red, green, blue, or white light through an organic light-emitting diode (OLED).

[0097] As shown in FIG. 4, the pixel circuit (PC) may include a plurality of transistors (T1 to T7) and a storage capacitor (Cst). The transistors (T1 to T7) and the storage capacitor (Cst) may be connected to signal lines (SL, SL-1, SL+1, EL, DL), a first initialization voltage line (VL1), a second initialization voltage line (VL2), and a driving voltage line (PL).

[0098] The signal lines (SL, SL-1, SL+1, EL, DL) may include a scan line (SL) that transmits a scan signal (Sn), a previous scan line (SL-1) that transmits a previous scan signal (Sn-1) to a first initialization transistor (T4), a subsequent scan line (SL+1) that transmits a scan signal (Sn) to a second initialization transistor (T7), a light emission control line (EL) that transmits a light emission control signal (En) to an operation control transistor (T5) and a light emission control transistor (T6), and a data line (DL) that crosses the scan line (SL) and transmits a data signal (Dm). The driving voltage line (PL) transmits a driving voltage (ELVDD) to the driving transistor (T1), the first initialization voltage line (VL1) transmits an initialization voltage (Vint) to the first initialization transistor (T4), and the second initialization voltage line (VL2) transmits an initialization voltage (Vint) to the second initialization transistor (T7).

[0099] The driving gate electrode (G1) of the driving transistor (T1) is connected to the lower electrode (CE1) of the storage capacitor (Cst), the driving source electrode (S1) of the driving transistor (T1) is connected to the lower driving voltage line (PL) via the operation control transistor (T5), and the driving drain electrode (D1) of the driving transistor (T1) is electrically connected to the pixel electrode of the main organic light-emitting diode (OLED) via the light emission control transistor (T6). The driving transistor (T1) receives a data signal (Dm) according to the switching operation of the switching transistor (T2) and supplies a driving current (IOLED) to the organic light-emitting diode (OLED).

[0100] The switching gate electrode (G2) of the switching transistor (T2) is connected to the scan line (SL), the switching source electrode (S2) of the switching transistor (T2) is connected to the data line (DL), and the switching drain electrode (D2) of the switching transistor (T2) is connected to the driving source electrode (S1) of the driving transistor (T1) and is connected to the lower driving voltage line (PL) via the operation control transistor (T5). The switching transistor (T2) is turned on according to the scan signal (Sn) received through the scan line (SL) and performs a switching operation to transmit the data signal (Dm) transmitted through the data line (DL) to the driving source electrode (S1) of the driving transistor (T1).

[0101] The compensation gate electrode (G3) of the compensation transistor (T3) is connected to the scan line (SL), and the compensation source electrode (S3) of the compensation transistor (T3) is connected to the driving drain electrode (D1) of the driving transistor (T1) and is connected to the pixel electrode of the organic light-emitting diode (OLED) via the light-emitting control transistor (T6). The compensation drain electrode (D3) of the compensation transistor (T3) is connected to the lower electrode (CE1) of the storage capacitor (Cst), the first initialization drain electrode (D4) of the first initialization transistor (T4), and the driving gate electrode (G1) of the driving transistor (T1). The compensation transistor (T3) is turned on according to the scan signal (Sn) received through the scan line (SL) to electrically connect the driving gate electrode (G1) and the driving drain electrode (D1) of the driving transistor (T1), thereby diode-connecting the driving transistor (T1).

[0102] The first initialization gate electrode (G4) of the first initialization transistor (T4) is connected to the previous scan line (SL-1), the first initialization source electrode (S4) of the first initialization transistor (T4) is connected to the first initialization voltage line (VL1), and the first initialization drain electrode (D4) of the first initialization transistor (T4) is connected to the lower electrode (CE1) of the storage capacitor (Cst), the compensation drain electrode (D3) of the compensation transistor (T3), and the driving gate electrode (G1) of the driving transistor (T1). The first initialization transistor (T4) is turned on according to the previous scan signal (Sn-1) received through the previous scan line (SL-1) and performs an initialization operation by transmitting an initialization voltage (Vint) to the driving gate electrode (G1) of the driving transistor (T1) to initialize the voltage of the driving gate electrode (G1) of the driving transistor (T1).

[0103] The operation control gate electrode (G5) of the operation control transistor (T5) is connected to the light emission control line (EL), the operation control source electrode (S5) of the operation control transistor (T5) is connected to the lower driving voltage line (PL), and the operation control drain electrode (D5) of the operation control transistor (T5) is connected to the driving source electrode (S1) of the driving transistor (T1) and the switching drain electrode (D2) of the switching transistor (T2).

[0104] The light-emitting control gate electrode (G6) of the light-emitting control transistor (T6) is connected to the light-emitting control line (EL), and the light-emitting control source electrode (S6) of the light-emitting control transistor (T6) is connected to the driving drain electrode (D1) of the driving transistor (T1) and the compensation source electrode (S3) of the compensation transistor (T3), and the light-emitting control drain electrode (D6) of the light-emitting control transistor (T6) is electrically connected to the second initialization source electrode (S7) of the second initialization transistor (T7) and the pixel electrode of the organic light-emitting diode (OLED).

[0105] The operation control transistor (T5) and the light emission control transistor (T6) are simultaneously turned on according to the light emission control signal (En) received through the light emission control line (EL), so that the driving voltage (ELVDD) is transmitted to the main organic light-emitting diode (OLED) and the driving current (IOLED) flows through the organic light-emitting diode (OLED).

[0106] The second initialization gate electrode (G7) of the second initialization transistor (T7) is subsequently connected to the scan line (SL+1), the second initialization source electrode (S7) of the second initialization transistor (T7) is connected to the light emission control drain electrode (D6) of the light emission control transistor (T6) and the pixel electrode of the main organic light-emitting diode (OLED), and the second initialization drain electrode (D7) of the second initialization transistor (T7) is connected to the second initialization voltage line (VL2).

[0107] Meanwhile, the scan line (SL) and the subsequent scan line (SL+1) are electrically connected to each other, so that the same scan signal (Sn) can be applied to the scan line (SL) and the subsequent scan line (SL+1). Accordingly, the second initialization transistor (T7) can be turned on according to the scan signal (Sn) received through the subsequent scan line (SL+1) to perform the operation of initializing the pixel electrode of the organic light-emitting diode (OLED).

[0108] The upper electrode (CE2) of the storage capacitor (Cst) is connected to the driving voltage line (PL), and the common electrode of the organic light-emitting diode (OLED) is connected to the common voltage (ELVSS). Accordingly, the organic light-emitting diode (OLED) can display an image by receiving a driving current (IOLED) from the driving transistor (T1) and emitting light.

[0109] In FIG. 4, the compensation transistor (T3) and the first initialization transistor (T4) are shown as having dual gate electrodes, but the compensation transistor (T3) and the first initialization transistor (T4) may have a single gate electrode.

[0110] Additionally, although the structure of a single pixel circuit (PC) is described in FIG. 4, multiple pixels (PX) having the same pixel circuit (PC) are arranged to form multiple rows, and in this case, the first initialization voltage line (VL1), the previous scan line (SL-1), the second initialization voltage line (VL2), and the subsequent scan line (SL+1) can be shared among neighboring pixels.

[0111] For example, the first initialization voltage line (VL1) and the previous scan line (SL-1) can be electrically connected to a second initialization thin-film transistor of another pixel circuit (PC) arranged along the second direction (y-direction). Thus, the previous scan signal applied to the previous scan line (SL-1) can be transmitted as a subsequent scan signal to the second initialization thin-film transistor of the other pixel circuit (PC). Likewise, the second initialization voltage line (VL2) and the subsequent scan line (SL+1) can be electrically connected to a first initialization thin-film transistor of another pixel circuit (PC) arranged adjacently along the second direction (y) with respect to the drawing to transmit the previous scan signal and the initialization voltage.

[0112] Figure 5 is a cross-sectional view schematically illustrating an example of a cross-section of a pixel of Figure 3.

[0113] Referring to FIG. 5, a buffer layer (111) formed to prevent impurities from penetrating into the semiconductor layer of a thin-film transistor may be disposed on the substrate (100).

[0114] The substrate (100) may be formed from various materials such as glass, metal, or plastic. According to one embodiment, the substrate (100) may be a flexible substrate and may include a polymer resin such as polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylenenaphthalate (PEN), polyethyleneterephthalate (PET), polyphenylenesulfide (PPS), polyallylate, polyimide (PI), polycarbonate (PC), or cellulose acetate propionate (CAP).

[0115] The buffer layer (111) may include an inorganic insulating material such as silicon nitride or silicon oxide, and may be a single layer or a multilayer.

[0116] On the substrate (100), a thin-film transistor (TFT), a capacitor (Cst), and an organic light-emitting diode (200) electrically connected to the thin-film transistor (TFT) may be disposed. The fact that the organic light-emitting diode (200) is electrically connected to the thin-film transistor (TFT) can be understood as the pixel electrode (211) being electrically connected to the thin-film transistor (TFT). The thin-film transistor (TFT) may be the driving transistor (T1) of FIG. 4.

[0117] A thin-film transistor (TFT) may include a semiconductor layer (132), a gate electrode (134), a source electrode (136S), and a drain electrode (136D). The semiconductor layer (132) may include an oxide semiconductor material. The semiconductor layer (132) may include amorphous silicon, polycrystalline silicon, or an organic semiconductor material. The gate electrode (134) may be formed as a single layer or a multilayer of one or more materials selected from, for example, aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), lithium (Li), calcium (Ca), molybdenum (Mo), titanium (Ti), tungsten (W), and copper (Cu), taking into consideration adhesion with adjacent layers, surface flatness of the stacked layers, and processability.

[0118] A gate insulating layer (112) comprising an inorganic material such as silicon oxide, silicon nitride, and / or silicon oxynitride may be interposed between the semiconductor layer (132) and the gate electrode (134). A first interlayer insulating layer (113) and a second interlayer insulating layer (114) comprising an inorganic material such as silicon oxide, silicon nitride, and / or silicon oxynitride may be disposed between the gate electrode (134), the source electrode (136S), and the drain electrode (136D). The source electrode (136S) and the drain electrode (136D) may be electrically connected to the semiconductor layer (132), respectively, through contact holes formed in the gate insulating layer (112), the first interlayer insulating layer (113), and the second interlayer insulating layer (114).

[0119] The source electrode (136S) and drain electrode (136D) may be formed as a single layer or multiple layers of one or more materials selected from aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), lithium (Li), calcium (Ca), molybdenum (Mo), titanium (Ti), tungsten (W), and copper (Cu).

[0120] The capacitor (Cst) includes a lower electrode (CE1) and an upper electrode (CE2) that overlap with the first interlayer insulating layer (113) in between. The capacitor (Cst) may overlap with a thin-film transistor (TFT). FIG. 5 illustrates that the gate electrode (134) of the thin-film transistor (TFT) is the lower electrode (CE1) of the capacitor (Cst). In another embodiment, the capacitor (Cst) may not overlap with the thin-film transistor (TFT). The capacitor (Cst) may be covered by the second interlayer insulating layer (114).

[0121] A pixel circuit including a thin-film transistor (TFT) and a capacitor (Cst) can be covered by a first insulating layer (115) and a second insulating layer (116). The first insulating layer (115) and the second insulating layer (116) may be organic insulating layers as planarizing insulating layers. The first insulating layer (115) and the second insulating layer (116) may include organic insulating materials such as general-purpose polymers like polymethylmethacrylate (PMMA) or polystyrene (PS), polymer derivatives having phenolic groups, acrylic polymers, imide polymers, aryl ether polymers, amide polymers, fluorine polymers, p-xylene polymers, vinyl alcohol polymers, and blends thereof. In one embodiment, the first insulating layer (115) and the second insulating layer (116) may include polyimide.

[0122] A display element, for example, an organic light-emitting diode (200), may be disposed on the second insulating layer (116). The organic light-emitting diode (200) may include a pixel electrode (211), an intermediate layer (231), and a counter electrode (251).

[0123] The pixel electrode (211) is disposed on the second insulating layer (116) and can be connected to a thin-film transistor (TFT) through a connecting electrode (181) on the first insulating layer (115). Wiring (183), such as a data line (DL) and a driving voltage line (PL), can be disposed on the first insulating layer (115).

[0124] The pixel electrode (211) may include a conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In2O3), indium gallium oxide (IGO), or aluminum zinc oxide (AZO). In another embodiment, the pixel electrode (211) may include a reflective film comprising silver (Ag), magnesium (Mg), aluminum (Al), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), or a compound thereof. In yet another embodiment, the pixel electrode (211) may further include a film formed of ITO, IZO, ZnO, or In2O3 above and below the aforementioned reflective film.

[0125] A third insulating layer (117) may be disposed on the second insulating layer (116). The third insulating layer (117) may be a pixel defining film that defines a pixel by covering the edge of the pixel electrode (211) and having a first opening (OP1) that exposes a part of the pixel electrode (211). The first opening (OP1) may correspond to a first region (A1). The third insulating layer (117) may serve to prevent arcs, etc. from occurring at the edge of the pixel electrode (211) by increasing the distance between the edge of the pixel electrode (211) and the opposing electrode (251). The third insulating layer (117) may be formed from an organic material such as polyimide (PI) or hexamethyldisiloxane (HMDSO).

[0126] The intermediate layer (231) includes a light-emitting layer. The light-emitting layer may include a polymer or low-molecular-weight organic material that emits light of a predetermined color. In one embodiment, the intermediate layer (231) may include a first functional layer disposed below the light-emitting layer and / or a second functional layer disposed above the light-emitting layer. The first functional layer and / or the second functional layer may include a layer that is integral across a plurality of pixel electrodes (211), or a layer patterned to correspond to each of the plurality of pixel electrodes (211).

[0127] The first functional layer may be a single layer or a multilayer. For example, if the first functional layer is formed from a polymer material, the first functional layer may be formed from polyethylene dihydroxythiophene (PEDOT) or polyaniline (PANI) as a single-layer hole transport layer (HTL). If the first functional layer is formed from a low-molecular-weight material, the first functional layer may include a hole injection layer (HIL) and a hole transport layer (HTL).

[0128] A second functional layer is not always provided. For example, when the first functional layer and the light-emitting layer are formed from a polymer material, it is desirable to form a second functional layer to improve the characteristics of the organic light-emitting diode. The second functional layer may be a single layer or a multilayer. The second functional layer may include an electron transport layer (ETL) and / or an electron injection layer (EIL).

[0129] The counter electrode (251) is positioned to face the pixel electrode (211) with the intermediate layer (231) in between. The counter electrode (251) may be made of a conductive material with a low work function. For example, the counter electrode (251) may include a (semi)transparent layer comprising silver (Ag), magnesium (Mg), aluminum (Al), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), lithium (Li), calcium (Ca), or alloys thereof. Alternatively, the counter electrode (251) may further include a layer such as ITO, IZO, ZnO, or In2O3 on the (semi)transparent layer comprising the aforementioned materials.

[0130] The counter electrode (251) can be placed on top of the intermediate layer (231) and the third insulating layer (117). The counter electrode (251) can be formed integrally with a plurality of organic light-emitting diodes (200) in the display area (DA) and can face a plurality of pixel electrodes (211).

[0131] A thin film encapsulation layer may be disposed on the upper surface of the counter electrode (251) as an encapsulation member (300). The thin film encapsulation layer serves to protect the organic light-emitting diode (200) from moisture or oxygen from the outside. The thin film encapsulation layer may have a multilayer structure. The thin film encapsulation layer may include a first inorganic layer, an organic layer, and a second inorganic layer. By forming the thin film encapsulation layer as a multilayer structure, even if a crack occurs within the thin film encapsulation layer, the crack may not be connected between the first inorganic layer and the organic layer or between the organic layer and the second inorganic layer. This prevents or minimizes the formation of a path through which moisture or oxygen from the outside penetrates into the display area. In other embodiments, the number of organic layers, the number of inorganic layers, and the stacking order may be changed.

[0132] The first inorganic layer covers the opposing electrode (251) and may include one or more inorganic insulating materials such as aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and silicon oxynitride. Since the first inorganic layer is formed along the structure below it, the upper surface may not be flat.

[0133] The organic layer covers the first inorganic layer and may have sufficient thickness. The upper surface of the organic layer may be substantially flat over the entire display area. The organic layer may comprise polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyimide, polyethylene sulfonate, polyoxymethylene, polyarylate, hexamethyldisiloxane, acrylic resin (e.g., polymethyl methacrylate, polyacrylic acid, etc.) or any combination thereof.

[0134] The second inorganic layer covers the organic layer and may include one or more inorganic insulating materials such as aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and silicon oxynitride. The second inorganic layer extends outward from the organic layer and contacts the first inorganic layer in the surrounding area, thereby preventing the organic layer from being exposed to the outside.

[0135] Meanwhile, the underlying structures may be damaged during the process of forming the thin film encapsulation layer. For example, when forming the first inorganic layer, the layer immediately below where the first inorganic layer is formed may be damaged. Therefore, to prevent damage to the underlying structures during the process of forming the thin film encapsulation layer, at least one capping layer and / or protective layer may be interposed between the counter electrode (251) and the thin film encapsulation layer. The protective layer may include an inorganic material.

[0136] FIG. 6 is a schematic cross-sectional view illustrating one embodiment of the I-I' section of FIG. 1.

[0137] Referring to FIG. 6, a display device (1) according to one embodiment of the present invention may include a display panel (10), a protective film layer (20), and a polarizing layer (50).

[0138] A display panel (10) may include a display area (DA) and a peripheral area (PA). At this time, pixels may be arranged in the display area (DA). The display panel (10) may provide an image using light emitted from the pixels. Each pixel (PX) may emit light using a display element. In one embodiment, the display element may be an organic light-emitting diode (OLED). In one example, each pixel (PX) may emit red, green, or blue light. In another example, each pixel (PX) may emit red, green, blue, or white light.

[0139] In one embodiment, the display panel (10) may include at least one of the substrate (100), organic light-emitting diode (200), and encapsulation member (300) described with reference to FIGS. 1 to 5. In a specific embodiment, the display panel (10) may include all of the substrate (100), organic light-emitting diode (200), and encapsulation member (300) described with reference to FIGS. 1 to 5. However, it is not limited thereto, and the display panel (10) may further include additional configurations that perform other functions. For example, the display panel (10) may further include various configurations for changing the light path or improving light extraction efficiency.

[0140] A protective film layer (20) may be placed on the display panel (10).

[0141] The protective film layer (20) is placed on the display panel (10) and can perform the function of protecting the display device (1) according to the present invention from external impact.

[0142] In one embodiment, the protective film layer (20) may include a protective film. The protective film may include various materials having good impact resistance and flexible or bendable properties. For example, the protective film may include a resin such as plastic. In other words, the protective film layer (20) may include an organic material. As an example, the protective film may be a urethane acrylate film containing urethane acrylate. Accordingly, the protective film layer (20) may be disposed on one side of the display panel (10) and perform the function of protecting the display device (1) of the present invention from external impact.

[0143] According to one embodiment of the present invention, the display device (1) may not include a window (or cover glass, hereinafter collectively referred to as a window) or a cover glass. Specifically, the display device (1) according to the present embodiment may be described as having a protective film layer (20) provided in the form of a film that functionally replaces a window formed of glass material. Accordingly, the display device (1) according to the present embodiment may have various superior effects compared to the case where it includes a window formed of glass material. For example, the thickness or weight of the entire device may be reduced in the display device (1) according to the present embodiment.

[0144] A polarizing layer (50) may be disposed on the protective film layer (20). For example, the polarizing layer (50) may be disposed on a side opposite to the display panel (10) with respect to the protective film layer (20). That is, the relative positional relationship of the display panel (10), the protective film layer (20), and the polarizing layer (50) may be in the order of the display panel (10), the protective film layer (20), and the polarizing layer (50) with respect to FIG. 6.

[0145] The polarization layer (50) can perform the function of selectively transmitting light emitted from a display element of the display element layer (DPL). Specifically, the polarization layer (50) transmits only light that vibrates in the same direction as the polarization axis among the light emitted from a display element of the display element layer (DPL), and can absorb or reflect light that vibrates in other directions.

[0146] When the polarization layer (50) is positioned as the outermost layer of the display device (1), specifically, when the polarization layer (50) is positioned as the uppermost layer of the display device (1) without an upper glass layer such as a window or cover glass, the polarization layer (50) may be made of a high-hardness material.

[0147] The polarization layer (50) may be disposed at the outermost edge of the display device (1). An upper substrate containing glass may not be included on the polarization layer (50) of the display device (1). In other words, an upper substrate layer containing at least glass may not be disposed on the polarization layer (50). The upper substrate may refer to a layer containing glass. However, the upper substrate is not limited to a layer containing at least glass, but may be a layer identical or similar to the display panel (10).

[0148] The high-hardness polarizing layer (50) may further include a hard coating layer (HC) on the top of the polarizing layer (50) to protect the polarizing layer (50) from external impact. In other words, the hard coating layer (HC) may be placed on the outermost edge of the display device (1). The hard coating layer (HC) has a scratch-resistant function and may have a hardness of approximately 9H.

[0149] The hard coating layer (HC) may be composed of organic materials such as polymer resins. However, the present invention is not limited thereto. The hard coating layer (HC) may also be composed of inorganic materials.

[0150] The hard coating layer (HC) may be the outermost layer of the display device (1). As a layer that the user touches directly, it can provide the user with a smoother and softer touch sensation.

[0151] The polarization layer (50) may be a film type or a liquid crystal coating type, but is not limited thereto.

[0152] According to one embodiment of the present invention, the display device (1) may include an adhesive layer (30, 40).

[0153] The adhesive layer (30, 40) can be interposed between the layers forming the display device (1) and perform the function of bonding the layers together.

[0154] The adhesive layer (30, 40) may be interposed between the display panel (10) and the protective film layer (20) and between the protective film layer (20) and the polarizing layer (50).

[0155] The adhesive layer (30, 40) may include a bonding film. As an example, the bonding film may be formed from a resin such as acrylic, polyimide, or polycarbonate that has light transparency.

[0156] In one embodiment, the adhesive layer (30, 40) may include a first adhesive layer (30) and a second adhesive layer (40). The first adhesive layer (30) may be interposed between the display panel (10) and the protective film layer (20) to perform the function of bonding the display panel (10) and the protective film layer (20). The second adhesive layer (40) may be interposed between the protective film layer (20) and the polarizing layer (50) to perform the function of bonding the protective film layer (20) and the polarizing layer (50).

[0157] In one embodiment, the first adhesive layer (30) and the second adhesive layer (40) may have different physical properties. For example, the first adhesive layer (30) and the second adhesive layer (40) may have different storage moduli. Accordingly, even when the display device (1) according to the present invention is subjected to a force in a direction of bending in one direction, the force applied to the display device (1) can be compensated by the first adhesive layer (30) and the second adhesive layer (40) having different storage moduli.

[0158] This will be discussed in detail later.

[0159] FIG. 7 is a schematic cross-sectional view illustrating another embodiment of the I-I' section of FIG. 1.

[0160] Referring to FIG. 7, when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2), the polarizing layer (50) can be positioned so as to be spaced inward from the edge of the protective film layer (20).

[0161] Compared to the above-described embodiment, the polarization layer (50) differs in that the position and area in which it is placed are different, so the following description will focus on these differences.

[0162] The polarization layer (50) may be disposed on the protective film layer (20). For example, the polarization layer (50) may be disposed on the side opposite to the display panel (10) with respect to the protective film layer (20). That is, the relative positional relationship of the display panel (10), the protective film layer (20), and the polarization layer (50) may be in the order of the display panel (10), the protective film layer (20), and the polarization layer (50) with respect to FIG. 7.

[0163] The polarization layer (50) may be positioned so as to be spaced inward from the edge of the protective film layer (20) when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2). Expressed from another perspective, when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2), the protective film layer (20) may include an area that does not overlap with the polarization layer (50). In this case, the area of ​​the polarization layer (50) may be smaller than the area of ​​the protective film layer (20).

[0164] In one embodiment, the polarizing layer (50) may be positioned such that each edge is spaced inward from the perimeter of the protective film layer (20). Expressed from another perspective, when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2), the protective film layer (20) may be positioned to surround the polarizing layer (50).

[0165] In one embodiment, the area where the polarizing layer (50) and the protective film layer (20) do not overlap may correspond to the peripheral area (PA) of the display device (1). In this case, the polarizing layer (50) may be considered to be positioned at a location corresponding to the display area (DA) of the display device (1).

[0166] As an optional embodiment, the distance between the edge of the polarization layer (50) and the edge of the protective film layer (20) may be 300 μm to 500 μm.

[0167] In one embodiment, the protective film layer (20) may be positioned to correspond to the display panel (10). For example, when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2), the edge of the protective film layer (20) and the edge of the display panel (10) may not be separated. In this case, the polarizing layer (50) may be positioned so as to be separated inward from the edge of the display panel (10) when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2). Additionally, the area of ​​the polarizing layer (50) may be smaller than the area of ​​the display panel (10).

[0168] In this way, when viewed from a direction perpendicular to the display panel (10) (the Z-axis direction in FIG. 1 and FIG. 2), the polarizing layer (50) is positioned so as to be spaced inward from the edge of the protective film layer (20), and thus the tolerance occurring during the lamination process of the polarizing layer (50) and the protective film layer (20) can be compensated.

[0169] Although not illustrated in FIG. 7, the polarization layer (50) may include the hard coating layer (HC) described in FIG. 6 to a extent that is not inconsistent with the above description.

[0170] FIGS. 8 and FIGS. 9 are drawings illustrating an example of a force acting on a polarization layer. Specifically, FIG. 8 is a drawing showing the polarization layer before deformation, and FIG. 9 is a drawing showing the polarization layer after deformation.

[0171] Here, the polarization layer (50) may be the polarization layer (50) in the embodiment described with reference to FIG. 6, the polarization layer (50) in the embodiment described with reference to FIG. 7, and the polarization layer (50) of the embodiments described with reference to FIG. 10 to FIG. 13 as described below.

[0172] Referring to FIGS. 8 and 9, the polarization layer (50) may change shape over time after being placed on the protective film layer (20). For example, as shown in FIG. 8, the polarization layer (50) may contract by receiving a force in a direction of contraction to the left and right relative to FIG. 8 over time after being placed on the protective film layer (20).

[0173] When the polarizing layer (50) contracts, the protective film layer (20) bonded to the polarizing layer (50) and the display panel (10) bonded to the protective film layer (20) may receive force in a direction of bending in one direction. That is, due to the contraction of the polarizing layer (50), the display device (1) according to the present invention may receive force in a direction of bending in one direction. For example, the display device (1) may receive a force that bends upward on both sides based on FIGS. 8 and 9. This may increase the risk of damage to the display device (1) and reduce the stability of the display device (1).

[0174] According to one embodiment of the present invention, the first adhesive layer (30) and the second adhesive layer (40) may have different physical properties. For example, the first adhesive layer (30) and the second adhesive layer (40) may have different storage moduli.

[0175] As a specific embodiment, the storage modulus of the first adhesive layer (30) may be greater than the storage modulus of the second adhesive layer (40). That is, the storage modulus of the second adhesive layer (40) in contact with the polarizing plate may be smaller than the storage modulus of the first adhesive layer (30).

[0176] As an optional embodiment, the storage modulus of the second adhesive layer (40) may be less than 1 / 6 of the storage modulus of the first adhesive layer (30). As an example, if the storage modulus of the first adhesive layer (30) is 0.3 MPa, the storage modulus of the second adhesive layer (40) may be less than 0.05 MPa.

[0177] In one embodiment, the first adhesive layer (30) and the second adhesive layer (40) may have different thicknesses. In a specific embodiment, the thickness of the first adhesive layer (30) may be smaller than the thickness of the second adhesive layer (40).

[0178] As an optional embodiment, the thickness of the second adhesive layer (40) may be 1 to 2 times the thickness of the first adhesive layer (30). As an example, if the thickness of the first adhesive layer (30) is 50 μm, the thickness of the second adhesive layer (40) may be 50 μm to 100 μm.

[0179] Therefore, when an external force (e.g., shrinkage stress of the polarization layer (50)) is applied, the second adhesive layer (40) can be deformed relatively easily. That is, according to the present embodiment, if the shape of the polarization layer (50) is deformed, the second adhesive layer (40) can be deformed together with the change in the shape of the polarization layer (50).

[0180] For example, as illustrated in FIGS. 8 and 9, when the polarizing layer (50) contracts, the second adhesive layer (40) may contract along the direction in which the polarizing layer (50) contracts on the side in contact with the polarizing layer (50) among the two sides. To explain this from another perspective, when the polarizing layer (50) contracts, the second adhesive layer (40) may be deformed by contracting so that the side in contact with the polarizing layer (50) among the two sides has a smaller area than the opposite side in order to compensate for the contraction of the polarizing layer (50).

[0181] That is, the second adhesive layer (40) deforms together with the deformation of the polarization layer (50), thereby preventing or reducing the stress caused by the shrinkage of the polarization layer (50) from being transmitted to the protective film layer (20) and the display panel (10). In addition, the adhesive layer may be suitable for application to a device having flexible or bendable characteristics.

[0182] FIG. 10 is a schematic cross-sectional view illustrating another embodiment of the I-I' section of FIG. 1, and FIG. 11 is an enlarged view of the X portion of FIG. 10.

[0183] Referring to FIGS. 10 and 11, a light-blocking member (60) may be further disposed between the protective film layer (20) and the polarizing layer (50).

[0184] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that it further includes a light-blocking member (60), and the following description will focus on this difference.

[0185] The light-blocking member (60) can be placed between the protective film layer (20) and the polarizing layer (50).

[0186] The light-blocking member (60) can perform the function of blocking light from passing through unintended areas. For example, the light-blocking member (60) can prevent or reduce the phenomenon of light passing through the protective film layer (20) passing through the surrounding area (PA) of the display device (1), i.e., light leakage. Here, the light-blocking member (60) may be referred to as a BM (Black Matrix), a light leakage prevention member, etc., but is not limited to such terms or expressions.

[0187] The light-blocking member (60) may include a material that does not transmit light. As an example, the light-blocking member (60) may include carbon black.

[0188] The light-blocking member (60) may be positioned to be in contact with the protective film layer (20). Expressed from another perspective, the light-blocking member (60) may be described as being attached to one side of the protective film layer (20). For example, the light-blocking member (60) may be attached to the upper surface of the protective film layer (20) based on FIGS. 10 and 11.

[0189] The adhesive layer may be positioned to surround at least a portion of the light-blocking member (60). To explain this from another perspective, the light-blocking member (60) may be described as being positioned inside the adhesive layer.

[0190] For example, the second adhesive layer (40) may be positioned to surround at least a portion of the light-blocking member (60). That is, the light-blocking member (60) may be positioned inside the second adhesive layer (40). The second adhesive layer (40) may be formed to have a thickness greater than that of the light-blocking member (60).

[0191] As a specific embodiment, the light-shielding member (60) may have a thickness less than half the thickness of the second adhesive layer (40). Here, the thickness of the second adhesive layer (40) may refer to a thickness in a direction parallel to the thickness (t) direction of the light-shielding member (60) with respect to FIG. 11.

[0192] As a specific embodiment, the light-shielding member (60) may have a thickness less than 3 / 10 of the thickness of the second adhesive layer (40). Here, the thickness of the second adhesive layer (40) may refer to a thickness in a direction parallel to the thickness (t) direction of the light-shielding member (60) with respect to FIG. 11.

[0193] When the light-shielding member (60) is formed to have a thickness less than half the thickness of the second adhesive layer (40), the second adhesive layer (40) can completely cover the light-shielding member (60) even if the second adhesive layer (40) shrinks due to viscoelasticity. That is, when the light-shielding member (60) is formed to be larger than half the thickness of the second adhesive layer (40), a problem may occur in which the light-shielding member (60) is exposed to the outside due to the shrinkage of the second adhesive layer (40).

[0194] In addition, if the light-shielding member (60) has a thickness less than 3 / 10 of the thickness of the second adhesive layer (40), the light-shielding member (60) can be completely covered despite process variation regarding shrinkage of the second adhesive layer (40).

[0195] As an optional embodiment, the thickness (t) of the light-shielding member (60) may be formed to be 15 μm. Accordingly, as shown in FIG. 11, one side of the light-shielding member (60) may be in contact with the protective film layer (20), one side may be exposed to the outside, and the remaining two sides may be surrounded by the second adhesive layer (40). By doing so, the adhesion characteristics of the polarization layer (50) and the second adhesive layer (40) may be improved, and the light leakage prevention efficiency of the light-shielding member (60) may be improved.

[0196] In one embodiment, the light-shielding member (60) may be arranged to overlap with the surrounding area (PA). For example, the width (W) of the light-shielding member (60) may be formed to be equal to the width of the surrounding area (PA). Additionally, in applying the embodiment described with reference to FIG. 7, the width (W) of the light-shielding member (60) may be greater than or equal to the distance between the edge of the polarizing layer (50) and the edge of the protective film layer (20). As an optional embodiment, the width (W) of the light-shielding member (60) may be 300 μm to 500 μm. If the width (W) of the light-shielding member (60) is less than 300 μm, light leakage may occur, and if the width (W) of the light-shielding member (60) is greater than 500 μm, the display function of the display device may be degraded.

[0197] In one embodiment, the light-blocking member (60) may be disposed along the edge of the protective film layer (20). For example, the light-blocking member (60) may be disposed on one side of the protective film layer (20) and may be disposed along the perimeter of the protective film layer (20). Accordingly, the light-blocking member (60) can prevent or reduce light leakage over the entire perimeter of the protective film layer (20).

[0198] FIG. 12 is a schematic cross-sectional view illustrating another embodiment of the I-I' section of FIG. 1, and FIG. 13 is an enlarged view of the Y portion of FIG. 12.

[0199] Referring to FIGS. 12 and 13, a light-blocking member (60) may be further disposed between the protective film layer (20) and the display panel (10).

[0200] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that light-blocking members (60) are arranged on both sides of the protective film layer (20), and the following description will focus on this difference.

[0201] The light-blocking member (60) can be placed between the protective film layer (20) and the polarizing layer (50) and between the protective film layer (20) and the display panel (10).

[0202] The light-blocking member (60) can perform the function of blocking light from passing through unintended areas. For example, the light-blocking member (60) can prevent or reduce the phenomenon of light passing through the protective film layer (20) passing through the surrounding area (PA) of the display device (1), i.e., light leakage.

[0203] The light-blocking member (60) may include a material that does not transmit light. As an example, the light-blocking member (60) may include carbon black.

[0204] The light-blocking member (60) may be positioned to be in contact with the protective film layer (20). Expressed from another perspective, the light-blocking member (60) may be described as being attached to both sides of the protective film layer (20). For example, the light-blocking member (60) may be attached to the upper and lower surfaces of the protective film layer (20) based on FIGS. 12 and 13.

[0205] The adhesive layer may be positioned to surround at least a portion of the light-blocking member (60). To explain this from another perspective, the light-blocking member (60) may be described as being positioned inside the adhesive layer.

[0206] For example, the first adhesive layer (30) may be arranged to surround at least a portion of the light-blocking member (60) attached to the lower surface of the protective film layer (20) based on FIGS. 12 and 13. That is, the light-blocking member (60) may be arranged inside the first adhesive layer (30). Additionally, the second adhesive layer (40) may be arranged to surround at least a portion of the light-blocking member (60) attached to the upper surface of the protective film layer (20) based on FIGS. 12 and 13. That is, the light-blocking member (60) may be arranged inside the second adhesive layer (40). By doing so, the adhesive characteristics of the polarizing layer (50) and the second adhesive layer (40) can be improved, and the light leakage prevention efficiency of the light-blocking member (60) can be improved.

[0207] In one embodiment, the light-blocking member (60) may have a thickness less than half the thickness of the first adhesive layer (30) or the second adhesive layer (40).

[0208] As a specific embodiment, the light-shielding member (60) may have a thickness less than half the thickness of the first adhesive layer (30). Here, the thickness of the first adhesive layer (30) may refer to a thickness in a direction parallel to the thickness (t) direction of the light-shielding member (60) with respect to FIG. 13.

[0209] As a specific embodiment, the light-blocking member (60) may have a thickness less than 3 / 10 of the thickness of the first adhesive layer (30). Here, the thickness of the first adhesive layer (30) may refer to a thickness in a direction parallel to the thickness (t) direction of the light-blocking member (60) with respect to FIG. 13.

[0210] When the light-shielding member (60) is formed to have a thickness less than half the thickness of the first adhesive layer (30), the first adhesive layer (30) can completely cover the light-shielding member (60) even if the first adhesive layer (30) shrinks due to viscoelasticity. That is, when the light-shielding member (60) is formed to be larger than half the thickness of the first adhesive layer (30), a problem may occur in which the light-shielding member (60) is exposed to the outside due to the shrinkage of the first adhesive layer (30).

[0211] In addition, if the light-shielding member (60) has a thickness less than 3 / 10 of the thickness of the first adhesive layer (30), the light-shielding member (60) can be completely covered despite process variation regarding shrinkage of the first adhesive layer (30).

[0212] Meanwhile, in this case, the light-blocking member (60) may have a thickness less than 1 / 2 of the thickness of the second adhesive layer (40) or less than 3 / 10 of the thickness of the second adhesive layer (40), as explained with reference to FIG. 10 and FIG. 11, so this will be omitted.

[0213] In one embodiment, the light-shielding member (60) may be arranged to overlap with the surrounding area (PA). For example, the width (W) of the light-shielding member (60) may be formed to be equal to the width of the surrounding area (PA). Additionally, in applying the embodiment described with reference to FIG. 7, the width (W) of the light-shielding member (60) may be greater than or equal to the distance between the edge of the polarizing layer (50) and the edge of the protective film layer (20). As an optional embodiment, the width (W) of the light-shielding member (60) may be 300 μm to 500 μm. If the width (W) of the light-shielding member (60) is less than 300 μm, light leakage may occur, and if the width (W) of the light-shielding member (60) is greater than 500 μm, the display function of the display device may be degraded.

[0214] In one embodiment, the light-blocking member (60) may be disposed along the edge of the protective film layer (20). For example, the light-blocking member (60) may be disposed along the perimeter on each side of the protective film layer (20). Accordingly, the light-blocking member (60) can prevent or reduce light leakage over the entire perimeter of the protective film layer (20).

[0215] In this way, the light-blocking member (60) is placed on both sides of the protective film layer (20), so that light leakage can be more completely prevented by the light-blocking member (60) or light leakage can be efficiently reduced.

[0216] FIG. 14 is a schematic cross-sectional view illustrating another embodiment of the II' section of FIG. 1, and FIG. 15 is an enlarged view of the Z section of FIG. 14.

[0217] Referring to FIGS. 14 and 15, the light-blocking member (60) may be arranged so that at least a portion is drawn in toward the protective film layer (20).

[0218] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that the light-blocking member (60) is arranged so that at least a portion is drawn in toward the protective film layer (20), and the following description will focus on this difference.

[0219] The light-blocking member (60) can be placed at least one of the space between the protective film layer (20) and the polarizing layer (50) and between the protective film layer (20) and the display panel (10).

[0220] In one embodiment, the light-blocking member (60) may be placed between the protective film layer (20) and the polarizing layer (50) and between the protective film layer (20) and the display panel (10).

[0221] The light-blocking member (60) can perform the function of blocking light from passing through unintended areas. For example, the light-blocking member (60) can prevent or reduce the phenomenon of light passing through the protective film layer (20) passing through the surrounding area (PA) of the display device (1), i.e., light leakage.

[0222] The light-blocking member (60) may include a material that does not transmit light. As an example, the light-blocking member (60) may include carbon black.

[0223] The light-blocking member (60) may be positioned so that at least a portion of it is drawn into the protective film layer (20). Expressed from another perspective, the light-blocking member (60) may be positioned on the surface of the first adhesive layer (30) and the surface of the second adhesive layer (40), and may also be positioned inside the protective film layer (20). For example, based on FIGS. 14 and 15, the light-blocking member (60) may be positioned so that at least a portion of it is drawn into the inner side of the protective film layer (20) from the upper surface of the first adhesive layer (30). Additionally, the light-blocking member (60) may be positioned so that at least a portion of it is drawn into the inner side of the protective film layer (20) from the lower surface of the second adhesive layer (40).

[0224] In this case, the protective film layer (20) may be positioned to surround at least a portion of the light-blocking member (60). To explain this from another perspective, the light-blocking member (60) may be described as being positioned inside the protective film layer (20). For example, the protective film layer (20) may be positioned to surround at least a portion of the light-blocking member (60) positioned above the first adhesive layer (30) and the light-blocking member (60) positioned below the second adhesive layer (40), based on FIGS. 14 and 15.

[0225] Accordingly, the adhesion characteristics between the protective film layer (20) and the display panel (10) and between the protective film layer (20) and the polarizing layer (50) can be improved, and the light leakage prevention efficiency of the light-blocking member (60) can be improved.

[0226] In one embodiment, the light-shielding member (60) may be arranged to overlap with the surrounding area (PA). For example, the width (W) of the light-shielding member (60) may be formed to be equal to the width of the surrounding area (PA). Additionally, in applying the embodiment described with reference to FIG. 7, the width (W) of the light-shielding member (60) may be greater than or equal to the distance between the edge of the polarizing layer (50) and the edge of the protective film layer (20). As an optional embodiment, the width (W) of the light-shielding member (60) may be 300 μm to 500 μm. If the width (W) of the light-shielding member (60) is less than 300 μm, light leakage may occur, and if the width (W) of the light-shielding member (60) is greater than 500 μm, the display function of the display device may be degraded.

[0227] In one embodiment, the light-blocking member (60) may be disposed along the edge of the protective film layer (20). For example, the light-blocking member (60) may be disposed along the perimeter on each side of the protective film layer (20). Accordingly, the light-blocking member (60) can prevent or reduce light leakage over the entire perimeter of the protective film layer (20).

[0228] In this way, the light-blocking member (60) is arranged so that at least a portion of it is drawn in toward the protective film layer (20) on both sides of the protective film layer (20), thereby preventing light leakage more completely or efficiently reducing light leakage by the light-blocking member (60).

[0229] FIG. 16 is a schematic cross-sectional view illustrating another embodiment of the II' section of FIG. 1, and FIG. 17 is an enlarged cross-sectional view of the X' section of FIG. 16.

[0230] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that the light-blocking member (60) is arranged so that at least a portion is drawn in toward the protective film layer (20) and the adhesive layer, and the following description will focus on this difference.

[0231] The light-blocking member (60) can be placed at least one of the space between the protective film layer (20) and the polarizing layer (50) and between the protective film layer (20) and the display panel (10).

[0232] In one embodiment, the light-blocking member (60) may be placed between the protective film layer (20) and the polarizing layer (50) and between the protective film layer (20) and the display panel (10).

[0233] The light-blocking member (60) can perform the function of blocking light from passing through unintended areas. For example, the light-blocking member (60) can prevent or reduce the phenomenon of light passing through the protective film layer (20) passing through the surrounding area (PA) of the display device (1), i.e., light leakage.

[0234] The light-blocking member (60) may include a material that does not transmit light. As an example, the light-blocking member (60) may include carbon black.

[0235] The light-blocking member (60) can be positioned so that at least a portion of it is incorporated into the protective film layer (20) and the adhesive layer.

[0236] As a specific embodiment, the light-blocking member (60) may be positioned so that at least a portion is inserted into the protective film layer (20) and the first adhesive layer (30). Expressed from another perspective, the light-blocking member (60) may be positioned between the protective film layer (20) and the first adhesive layer (30), with at least a portion inserted in the direction toward the protective film layer (20) and the first adhesive layer (30). Additionally, the light-blocking member (60) may be positioned so that at least a portion is inserted into the protective film layer (20) and the second adhesive layer (40). Expressed from another perspective, the light-blocking member (60) may be positioned between the protective film layer (20) and the second adhesive layer (40), with at least a portion inserted in the direction toward the protective film layer (20) and the second adhesive layer (40).

[0237] In this case, the light-blocking member (60) disposed between the protective film layer (20) and the first adhesive layer (30) may be surrounded at least partially by the protective film layer (20) and the first adhesive layer (30). For example, based on FIGS. 16 and 17, the light-blocking member (60) disposed above the first adhesive layer (30) may be disposed such that at least partially is surrounded by the first adhesive layer (30) and the protective film layer (20).

[0238] Additionally, a light-blocking member (60) disposed between the protective film layer (20) and the second adhesive layer (40) may be surrounded at least partially by the protective film layer (20) and the second adhesive layer (40). For example, based on FIGS. 16 and 17, a light-blocking member (60) disposed below the second adhesive layer (40) may be disposed such that at least partially is surrounded by the second adhesive layer (40) and the protective film layer (20).

[0239] Accordingly, the adhesion characteristics between the protective film layer (20) and the display panel (10) and between the protective film layer (20) and the polarizing layer (50) can be improved, and the light leakage prevention efficiency of the light-blocking member (60) can be improved.

[0240] In one embodiment, the light-shielding member (60) may be arranged to overlap with the surrounding area (PA). For example, the width (W) of the light-shielding member (60) may be formed to be equal to the width of the surrounding area (PA). Additionally, in applying the embodiment described with reference to FIG. 7, the width (W) of the light-shielding member (60) may be greater than or equal to the distance between the edge of the polarizing layer (50) and the edge of the protective film layer (20). As an optional embodiment, the width (W) of the light-shielding member (60) may be 300 μm to 500 μm. If the width (W) of the light-shielding member (60) is less than 300 μm, light leakage may occur, and if the width (W) of the light-shielding member (60) is greater than 500 μm, the display function of the display device may be degraded.

[0241] In one embodiment, the light-blocking member (60) may be disposed along the edge of the protective film layer (20). For example, the light-blocking member (60) may be disposed along the perimeter on each side of the protective film layer (20). Accordingly, the light-blocking member (60) can prevent or reduce light leakage over the entire perimeter of the protective film layer (20).

[0242] In this way, the light-blocking member (60) is arranged such that at least a portion is drawn in toward the protective film layer (20) and the adhesive layer on both sides of the protective film layer (20), thereby preventing light leakage more completely or efficiently reducing light leakage by the light-blocking member (60).

[0243] FIG. 18 is a schematic diagram illustrating another embodiment of the I-I' cross-section of FIG. 1.

[0244] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that the housing (70) is arranged along at least a portion of the outer perimeter of the display panel (10), and the following description will focus on this difference.

[0245] Referring to FIG. 18, a housing (70) may be placed on at least a portion of the outer perimeter of the display panel (10).

[0246] In one embodiment, the housing (70) may be positioned along the perimeter of the display panel (10) to cover the perimeter of the display panel (10). For example, the housing (70) may be positioned along the side of the display panel (10). Additionally, the housing (70) may be positioned so as not to cover the top of the display panel (10). To explain this in another way, the housing (70) may cover the perimeter of the display panel (10), but the top of the display panel (10) may be open.

[0247] In one embodiment, the housing (70) may have a height that covers at least one side of the display panel (10) and the protective film layer (20), the first adhesive layer (30), the second adhesive layer (40), and the polarizing layer (50) disposed on the display panel (10). In a specific embodiment, the housing (70) may have a height that covers the entire perimeter of the display panel (10) and the protective film layer (20), the first adhesive layer (30), the second adhesive layer (40), and the polarizing layer (50) disposed on the display panel (10).

[0248] Therefore, the expression "side of the display panel (10)" below may be interpreted not merely as meaning the display panel (10), but as including multiple layers placed on the display panel (10).

[0249] Meanwhile, although a light-blocking member (60) is not shown in the drawing, it is obvious that a light-blocking member (60) may be further disposed between the various layers on the display panel (10), as in the embodiments described above with reference to FIGS. 6 to 17.

[0250] In one embodiment, an attachment part (80) may be further disposed on one side of the housing (70). For example, the attachment part (80) may be disposed on the side facing the display panel (10) among the two sides of the housing (70).

[0251] The attachment part (80) is positioned on one side of the housing (70) and can perform the function of attaching the housing (70) to the side of the display panel (10).

[0252] In one embodiment, a sealing portion (90) may be further disposed on the side of the display panel (10). The sealing portion (90) may perform the function of ensuring that the side of the housing (70) and the display panel (10) are more stably attached.

[0253] That is, the attachment part (80) and the sealing part (90) are positioned between the display panel (10) and the housing (70) and can perform the function of strongly attaching the side of the display panel (10) and the housing (70) to each other.

[0254] FIG. 19 is a schematic diagram illustrating another embodiment of the I-I' cross-section of FIG. 1.

[0255] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that the housing (70) is arranged along at least a portion of the outer side of the display panel (10), and the following description will focus on this difference.

[0256] Referring to FIG. 19, a housing (70) may be positioned along at least a portion of the outer side of the display panel (10).

[0257] The housing (70) may be of the bezel type. For example, the display panel (10) may be inserted into the housing (70) so that the housing (70) surrounds the outside of the display panel (10).

[0258] The housing (70) can cover the perimeter of the display panel (10) and the protective film layer (20), the first adhesive layer (30), the second adhesive layer (40), and the polarizing layer (50) disposed on the display panel (10).

[0259] In one embodiment, the housing (70) may be positioned to surround the sides of the display panel (10), the protective film layer (20), the first adhesive layer (30), the second adhesive layer (40), and the polarizing layer (50). In this case, the housing (70) may be positioned to overlap with at least a portion of the side of the polarizing layer (50). For example, the housing (70) may be positioned to be in contact with the side of the polarizing layer (50). Additionally, the housing (70) may be positioned to overlap with at least a portion of the side of the second adhesive layer (40).

[0260] Meanwhile, although a light-blocking member (60) is not shown in the drawing, it is obvious that a light-blocking member (60) may be further disposed between the various layers on the display panel (10), as in the embodiments described above with reference to FIGS. 6 to 17.

[0261] In one embodiment, an attachment part (80) may be further disposed on one side of the housing (70). For example, the attachment part (80) may be disposed on the side facing the display panel (10) among the two sides of the housing (70).

[0262] The attachment part (80) is positioned on one side of the housing (70) and can perform the function of attaching the housing (70) to the side of the display panel (10).

[0263] At this time, if the upper part of the second adhesive layer (40) forms a slope due to the shrinkage of the polarization layer (50), the attachment portion (80) can be arranged along the slope of the second adhesive layer (40).

[0264] Meanwhile, although the drawing shows the attachment portion (80) being arranged continuously on one side of the housing (70), multiple attachment portions (80) may be arranged spaced apart from each other on one side of the housing (70).

[0265] FIG. 20 is a schematic diagram illustrating another embodiment of the I-I' cross-section of FIG. 1.

[0266] Compared to the previously described embodiments, the display device (1) according to the present embodiment differs in that the housing (70) is arranged along at least a portion of the outer side of the display panel (10), and the following description will focus on this difference.

[0267] Referring to FIG. 20, a housing (70) may be positioned along at least a portion of the outer side of the display panel (10).

[0268] The housing (70) may be of the bezel type. For example, the display panel (10) may be inserted into the housing (70) so that the housing (70) surrounds the outside of the display panel (10).

[0269] The housing (70) can cover the perimeter of the display panel (10) and the protective film layer (20), the first adhesive layer (30), the second adhesive layer (40), and the polarizing layer (50) disposed on the display panel (10).

[0270] In one embodiment, the housing (70) may be positioned to surround the sides of the display panel (10), the protective film layer (20), the first adhesive layer (30), and the second adhesive layer (40). At this time, the housing (70) may be positioned to overlap with the upper surface of the polarization layer (50). Additionally, the housing (70) may be positioned to overlap with at least a portion of the upper surface of the second adhesive layer (40). For example, the housing (70) may be extended beyond a height that covers the entire perimeter of the display panel (10), the protective film layer (20), the first adhesive layer (30), and the second adhesive layer (40), and may be folded in a direction toward the polarization layer (50) to overlap with at least a portion of the upper surface of the polarization layer (50). To explain this in another way, the upper side of the housing (70) may be positioned to surround at least a portion of the perimeter of the upper surface of the polarization layer (50), so that a portion of the polarization layer (50) may be open.

[0271] Meanwhile, although a light-blocking member (60) is not shown in the drawing, it is obvious that a light-blocking member (60) may be further disposed between the various layers on the display panel (10), as in the embodiments described above with reference to FIGS. 6 to 17.

[0272] In one embodiment, an attachment part (80) may be further disposed on one side of the housing (70). For example, the attachment part (80) may be disposed on the side facing the display panel (10) among the two sides of the housing (70).

[0273] The attachment part (80) is positioned on one side of the housing (70) and can perform the function of attaching the housing (70) to the side of the display panel (10).

[0274] In one embodiment, the attachment portion (80) may be positioned between the display panel (10) and the housing (70). Meanwhile, the attachment portion (80) may also be positioned between the protective film layer (20), the first adhesive layer (30), and the second adhesive layer (40) on the display panel (10). Additionally, the attachment portion (80) may also be positioned between the housing (70) and the upper surface of the polarization layer (50). That is, since the housing (70) is positioned to overlap with the upper surface of the polarization layer (50), the attachment portion (80) is positioned between the housing (70) and the upper surface of the polarization layer (50), so that the housing (70) and the upper surface of the polarization layer (50) can be stably attached.

[0275] Hereinafter, a method for manufacturing a display device (1) according to an embodiment of the present invention will be described. For convenience of explanation, details that are identical to those previously described regarding the display device (1) or that can be easily applied by a person with ordinary knowledge in the technical field to which the present invention belongs will be omitted or summarized below.

[0276] FIGS. 21 and 22 are flowcharts schematically illustrating a method for manufacturing a display device according to an embodiment of the present invention, and FIGS. 23 to 26 are diagrams schematically illustrating a method for manufacturing a display device according to an embodiment of the present invention.

[0277] Referring to FIGS. 21 to 26, a method for manufacturing a display device (1) according to another embodiment of the present invention may include the step of preparing a protective film layer (20) (S10), the step of placing a light-blocking member (60) on at least one surface of the protective film layer (20) (S20), and the step of placing a polarizing layer (50) on one surface of the protective film layer (20) on which the light-blocking member (60) is placed, and placing a display panel (10) on the other surface (S30).

[0278] Here, the protective film layer (20), the light-blocking member (60), and the display panel (10) may be those described in the embodiments described above.

[0279] In one embodiment, the step (S20) of placing a light-blocking member (60) on at least one surface of a protective film layer (20) may include the step (S21) of positioning the light-blocking member (60) on at least one surface of the protective film layer (20), the step (S22) of pressing the light-blocking member (60), the step (S23) of curing the pressed light-blocking member (60), and the step (S24) of laminating an adhesive layer to the protective film layer (20) to cover the protective film layer (20) and the light-blocking member (60).

[0280] Referring to FIG. 23, the step (S21) of positioning a light-blocking member (60) on at least one surface of a protective film layer (20) may be a step of bringing at least a portion of the light-blocking member (60) into contact with at least one surface of the prepared protective film layer (20). For example, the light-blocking member (60) may be prepared in a state that is not hardened and has flexibility. The light-blocking member (60) may be positioned so that at least a portion of it comes into contact with the protective film layer (20).

[0281] In one embodiment, the light-blocking member (60) may be positioned on only one side of the protective film layer (20), that is, on either the upper or lower side based on FIG. 23.

[0282] In another embodiment, the light-blocking member (60) may be positioned on both sides of the protective film layer (20), that is, on both the upper and lower surfaces based on FIG. 23.

[0283] Referring to FIG. 24, the step (S22) of pressing the light-shielding member (60) may be a step of pressing the light-shielding member (60) to bring it into contact with the protective film layer (20) over a wide area.
