Throughout the specification, the same reference numerals refer to the same components. Furthermore, in describing the present invention, if it is determined that a detailed description of related prior art may unnecessarily obscure the essence of the present invention, such detailed description is omitted. Where terms such as "includes," "has," or "is made up" are used in the present invention, other parts may be added unless "only" is used.

[0027] Throughout the specification, the same reference numerals refer to the same components.

[0028] The area and thickness of each component shown in the drawings are illustrated for convenience of explanation, and the present invention is not necessarily limited to the area and thickness of the illustrated components.

[0029] The features of each of the various embodiments of the present invention may be combined or combined with one another, either partially or wholly, and may technically enable various interlocking and operation. Each embodiment may be implemented independently of one another or may be implemented together in an associated relationship.

[0030] Various embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0031] FIG. 1 is a plan view of a display device according to one embodiment of the present invention. FIG. 2 is an enlarged plan view of a display device according to one embodiment of the present invention. In FIG. 1 and FIG. 2, for convenience of explanation, only the display panel (140) and the conductive light-shielding member (170) among the various components of the display device (100) are shown.

[0032] The display panel (140) is a panel on which an image is displayed, and may be configured with a display element for displaying the image, a circuit, wiring, and components for driving the display element.

[0033] Referring to FIGS. 1 and FIGS. 2, the display panel (140) includes a display area (AA), a non-display area (NA), and a camera area (CA).

[0034] The display area (AA) is an area where a plurality of subpixels (SP) are arranged to display an image. Each of the plurality of subpixels (SP) is an individual unit that emits light, and a light-emitting element and a driving circuit are formed in each of the plurality of subpixels (SP). For example, a display element for displaying an image and a circuit for driving the display element may be arranged in the plurality of subpixels (SP). For example, if the display device (100) is an organic light-emitting display device, the display element may include an organic light-emitting element, and if the display device (100) is a liquid crystal display device, the display element may include a liquid crystal element. The plurality of subpixels (SP) may include a red subpixel (SP), a green subpixel (SP), a blue subpixel (SP) and / or a white subpixel (SP), but are not limited thereto.

[0035] The non-display area (NA) is an area where an image is not displayed, and it is an area where various wiring, driving ICs, etc., are placed to drive multiple subpixels (SP) located in the display area (AA). For example, various ICs and driving circuits, such as gate driver ICs and data driver ICs, may be placed in the non-display area (NA). The non-display area (NA), where an image is not displayed, may also be defined as a bezel area.

[0036] Meanwhile, the non-display area (NA) may be defined as an area surrounding the display area (AA) as shown in FIG. 1. However, the non-display area (NA) may be defined as an area extending from the display area (AA), or as an area where a plurality of subpixels (SP) are not placed, and is not limited thereto.

[0037] A camera area (CA) is placed within a display area (AA). A camera area (CA) is placed between multiple subpixels (SP) in the display area (AA). The camera area (CA) is an area where optical components, such as a camera or a proximity sensor, are placed. The camera area (CA) includes a through-hole (TH) that penetrates a part of the display device (100) to place optical components. A space for placing optical components can be secured by forming a through-hole (TH) that penetrates the display panel (140).

[0038] Meanwhile, some of the light emitted from multiple subpixels (SP) may travel toward a camera area (CA), i.e., a through hole (TH), located between the multiple subpixels (SP). However, if the light from the multiple subpixels (SP) that travels toward the through hole (TH) is transmitted to an optical component such as a camera, noise may occur, which may reduce the reliability of the optical component. Accordingly, a conductive light-blocking member (170) may be placed in the through hole (TH) to prevent the light emitted from the multiple subpixels (SP) from being transmitted into the through hole (TH).

[0039] Hereinafter, for a more detailed explanation of the conductive light-blocking member (170) and the display device (100), we will refer to FIGS. 3a to 4.

[0040] FIGS. 3a and FIGS. 3b are cross-sectional views according to III-III' of FIGS. 2. FIGS. 3a is a cross-sectional view illustrating a case where the size of the through hole (TH) formed in the metal plate (160) and the display panel (140) is different, and FIGS. 3b is a cross-sectional view illustrating a case where the size of the through hole (TH) formed in the metal plate (160) and the display panel (140) is the same. Referring to FIGS. 3a through 4, a display device (100) according to one embodiment of the present invention includes a cover window (110), an adhesive layer (120), a polarizing plate (130), a display panel (140), a back plate (150), and a metal plate (160).

[0041] A cover window (110) is placed on a display panel (140). The cover window (110) can protect the polarizing plate (130) and the display panel (140) below the cover window (110) from external impact, moisture, heat, etc. The cover window (110) may be made of a material having impact resistance and light transmittance. For example, the cover window (110) may be a substrate made of glass or a thin film made of plastic materials such as polymethylmethacrylate (PMMA), polyimide (PI), and polyethylene terephthalate (PET), but is not limited thereto. Additionally, the cover window (110) may be referred to by various names such as front member, cover glass, etc., as exemplary names, but is not limited thereto.

[0042] A polarizing plate (130) is disposed between the cover window (110) and the display panel (140). The polarizing plate (130) can selectively transmit light to reduce the reflection of external light incident on the display panel (140). Specifically, the display panel (140) includes various metal materials applied to thin-film transistors, wiring, electroluminescent devices, etc. Accordingly, external light incident on the display panel (140) may be reflected from the metal material, and the visibility of the display device (100) may be reduced due to the reflection of external light. Accordingly, by placing the polarizing plate (130) on one side of the display panel (140), the reflection of external light can be prevented and the outdoor visibility of the display device (100) can be improved. However, the components of the display device (100) illustrated in FIGS. 3a and 3b are exemplary, and the polarizing plate (130) may be omitted depending on the embodiment of the display device (100).

[0043] Additionally, an adhesive layer (120) can be formed between the polarizing plate (130) and the cover window (110) to allow the cover window (110) to be attached and positioned on the polarizing plate (130). The adhesive layer (120) may be made of an adhesive material, for example, OCA (Optical Clear Adhesive), PSA (Pressure Sensitive Adhesive), etc., but is not limited thereto.

[0044] A backplate (150) is placed below the display panel (140). When the substrate forming the display panel (140) is made of a plastic material such as polyimide, the manufacturing process of the display device (100) proceeds with a support substrate made of glass placed below the substrate, and after forming components such as a polarizer on the display panel (140), the support substrate can be released. However, since components to support the substrate are required even after the support substrate is released, a backplate (150) for supporting the substrate can be placed below the substrate of the display panel (140). In addition, the backplate (150) not only supports the display panel (140) but also protects the display panel (140) from external moisture, heat, shock, etc. The backplate (150) may be a thin film made of, for example, polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), etc.

[0045] A metal plate (160) is placed on the lower part of the backplate (150). The metal plate (160) can protect and support the configuration on the metal plate (160). The metal plate (160) is made of a rigid material so that it can minimize the occurrence of dents, etc. caused by external impacts. Also, the metal plate (160) can function as a heat dissipation member that releases heat generated when the display device (100) is operated. In addition, the metal plate (160) is made of a material with excellent electrical conductivity so that it can release static electricity generated in the cover window (110) to the outside together with the conductive light-blocking member (170). To this end, the metal plate (160) may be made of a material with excellent thermal and electrical conductivity, such as copper (Cu) or graphite, but is not limited thereto.

[0046] Meanwhile, in this specification, the configuration placed below the display panel (140) is referred to as a backplate (150) and a metal plate (160), but the backplate (150) and the metal plate (160) may be referred to by other names, for example, the metal plate (160) may be referred to as the first plate and the backplate (150) as the second plate, and are not limited thereto.

[0047] A through hole (TH) is formed in the components of the display device (100), excluding the cover window (110). The through hole (TH) can be formed by penetrating the adhesive layer (120), the polarizer (130), the display panel (140), the backplate (150), and the metal plate (160). The through hole (TH) is an empty space for placing an optical component, such as a camera, in the display area (AA). The optical component is placed within the through hole (TH) to recognize the external environment outside the cover window (110). The optical component can operate by recognizing external light, etc., transmitted to the optical component through the cover window (110). At this time, the through hole (TH) is not formed in the cover window (110) to prevent foreign substances, etc. from penetrating into the through hole (TH).

[0048] Meanwhile, the size of the through hole (TH) of the metal plate (160) may be configured differently depending on the order of the metal plate (160) attachment process and the through hole (TH) formation process. For convenience of explanation, the through hole (TH) formed continuously in the adhesive layer (120), polarizing plate (130), display panel (140), and back plate (150), that is, the through hole (TH) arranged along the adhesive layer (120), polarizing plate (130), display panel (140), and back plate (150), will be referred to as the first through hole (TH1), and the through hole (TH) formed in the metal plate (160) will be referred to as the second through hole (TH2). However, the first through hole (TH1) and the second through hole (TH2) are exemplary, and the first through hole (TH1) may be referred to as the first hole and the second through hole (TH2) as the second hole, and is not limited thereto.

[0049] For example, referring to FIG. 3a, a first through hole (TH1) having a first diameter (D1) is formed in the adhesive layer (120), polarizer (130), display panel (140), and backplate (150) at once, and then a metal plate (160) having a second through hole (TH2) having a second diameter (D2) can be attached to the back surface of the backplate (150). At this time, the first diameter (D1) of the first through hole (TH1) may be smaller than the second diameter (D2) of the second through hole (TH2). If the second through hole (TH2) is smaller than the first through hole (TH1), it may be difficult to align the second through hole (TH2) and the first through hole (TH1) when attaching the metal plate (160), and it may be difficult to form the conductive light-blocking member (170), which will be described later, inside the first through hole (TH1). Accordingly, if a through hole (TH) is formed before attaching the metal plate (160), a display device (100) can be manufactured by attaching an adhesive layer (120) with a first through hole (TH1) formed therein, a polarizing plate (130), a display panel (140), and a back plate (150), and a metal plate (160) with a second through hole (TH2) formed therein having a diameter larger than that of the first through hole (TH1).

[0050] For another example, referring to FIG. 3b, a through hole (TH) can be formed after the adhesive layer (120), polarizer (130), display panel (140), backplate (150), and metal plate (160) are attached. In this case, the diameter of the first through hole (TH1) formed in the adhesive layer (120), polarizer (130), display panel (140), and backplate (150) and the diameter of the second through hole (TH2) formed in the metal plate (160) may be the same. However, the size of the through hole (TH) formed in the adhesive layer (120), polarizer (130), display panel (140), backplate (150), and metal plate (160) may be configured in various ways and is not limited thereto.

[0051] A light-blocking member (170) is placed inside the through hole (TH). The light-blocking member (170) may be made of a conductive material and may be referred to as a conductive light-blocking member (170). The conductive light-blocking member (170) is configured to block light from the display panel (140) from entering the through hole (TH) and to discharge static electricity generated from the cover window (110). The conductive light-blocking member (170) can cover a portion of the cover window (110) exposed in the through hole (TH), the side of the adhesive layer (120), the side of the polarizing plate (130), the side of the display panel (140), the side of the back plate (150), and the side of the metal plate (160). The conductive light-blocking member (170) can be placed to cover the inner surface of the through hole (TH) and a portion of the back surface of the cover window (110) corresponding to the circumference of the through hole (TH). One end of the conductive light-blocking member (170) is placed on the cover window (110), and the other end may be in contact with the metal plate (160). The conductive light-blocking member (170) may overlap with a portion of the metal plate (160).

[0052] For example, referring to FIG. 3a, the conductive light-shielding member (170) can cover the back surface of the cover window (110), the boundary portion between the back surface of the cover window (110) and the side of the adhesive layer (120), the side of the adhesive layer (120), the side of the polarizer (130), the side of the display panel (140), and the side of the backplate (150). The conductive light-shielding member (170) can also cover the back surface of the backplate (150) exposed at the second through hole (TH2), the boundary portion between the back surface of the backplate (150) and the side of the metal plate (160), and the side of the metal plate (160). Accordingly, if the second through-hole (TH2) of the metal plate (160) is larger than the first through-hole (TH1) of the adhesive layer (120), polarizer (130), display panel (140), and backplate (150), the conductive light-shielding member (170) can cover up to the portion of the backplate (150) exposed at the second through-hole (TH2).

[0053] For another example, referring to FIG. 3b, the conductive light-blocking member (170) can cover the back surface of the cover window (110), the boundary portion between the back surface of the cover window (110) and the side of the adhesive layer (120), the side of the adhesive layer (120), the side of the polarizer (130), the side of the display panel (140), the side of the backplate (150), and the side of the metal plate (160).

[0054] Meanwhile, referring to FIGS. 3a and 3b, the conductive light-shielding member (170) covers only the side of the metal plate (160) and does not cover the back surface of the metal plate (160). That is, the end of the conductive light-shielding member (170) is not placed outside the through hole (TH) but can be placed only inside the through hole (TH). If the conductive light-shielding member (170) is placed to cover the back surface of the metal plate (160), interference between the conductive light-shielding member (170) and other components on the metal plate (160) may occur, or a short circuit may occur. For example, a circuit board for driving optical components may be placed on the back plate, and the conductive light-shielding member (170) on the back surface of the metal plate (160) and the circuit board may interfere with each other, causing a short circuit defect. Additionally, if a component such as a frame is attached to the back surface of the metal plate (160), interference with the conductive light-shielding member (170) may occur. Therefore, the conductive light-blocking member (170) can be placed only inside the through hole (TH).

[0055] The conductive light-blocking member (170) may be made of an opaque and electrically conductive material to prevent light leakage while discharging static electricity. The conductive light-blocking member (170) may be made of conductive ink or conductive paste, for example, conductive ink mixed with conductive particles such as carbon black or a conductive polymer such as PEDOT:PSS (poly(3,4-ethylenedioxythiophene)), or conductive paste made of a material such as silver. Additionally, the conductive light-blocking member (170) may have a resistance of 0 to 10^6 Ω to discharge static electricity. However, the conductive light-blocking member (170) may be formed of various materials other than those described above, and is not limited thereto.

[0056] Meanwhile, the conductive light-shielding member (170) can be formed using processes such as pneumatic spray coating or electrostatic spray coating. For example, pneumatic spray coating is a method of using air pressure to push out and spray a substance inside a syringe, and electrostatic spray coating is a method of applying voltage to a substance to impart an electric charge, and then spraying the charged substance using a spray nozzle. If the conductive light-shielding member (170) is formed using a pneumatic spray coating or electrostatic spray coating method, the viscosity of the conductive light-shielding member (170) may be about 10,000 cPs or less. However, the conductive light-shielding member (170) may be formed in various other ways and is not limited thereto.

[0057] A printed pattern (BP) is placed between the cover window (110) and the conductive light-blocking member (170). The printed pattern (BP) may be placed along the perimeter of the through hole (TH) on the back of the cover window (110). At least one of the first through hole (TH1) and the second through hole (TH2) may overlap with the printed pattern (BP).

[0058] At this time, the printed pattern (BP) can discharge static electricity generated in the cover window (110) to the metal plate (160) together with the conductive light-blocking member (170). The printed pattern (BP) can be formed from an insulating material or a conductive material such as the conductive light-blocking member (170), and, for example, can be made of black ink or an ink containing a conductive material or silver paste. At this time, even if the printed pattern (BP) is formed from an insulating material and the conductive light-blocking member (170) is indirectly connected to the cover window (110) through the printed pattern (BP), static electricity generated in the cover window (110) can be easily discharged. Meanwhile, although the configuration formed on the back surface of the cover window (110) in this specification is referred to as the printed pattern (BP), the printed pattern (BP) may also be referred to as a pattern and is not limited thereto.

[0059] Meanwhile, among the configurations in direct contact with the conductive light-shielding member (170), a plurality of wires, etc., are arranged on the substrate to supply various signals. Even if the conductive light-shielding member (170) is formed without a separate insulating layer on the inner side of the through hole (TH) where the interior of the display panel (140) is directly exposed, the display panel (140) can be easily driven.

[0060] Referring to FIG. 4, the specific structure of the display panel (140) in the camera area (CA) will be described below.

[0061] FIG. 4 is an enlarged cross-sectional view of a display panel of a display device according to one embodiment of the present invention.

[0062] Referring to FIG. 4, the display panel (140) includes a substrate (SUB), a buffer layer (BUF), a gate insulating layer (GI), a first interlayer insulating layer (INT1), a second interlayer insulating layer (INT2), a third interlayer insulating layer (INT3), a planarization layer (PLN), a light-emitting layer (EL) and a cathode (CD) of a light-emitting element, an encapsulation portion (EC), an additional planarization layer (TPLN), and a plurality of dams (DM).

[0063] A substrate (SUB) is a supporting member for supporting other components of a display device (100) and may be made of an insulating material. For example, the substrate (SUB) may be made of glass or resin, etc. Additionally, the substrate (SUB) may be made of a polymer or plastic such as polyimide (PI), etc., or may be made of a material having flexibility.

[0064] As a plurality of wirings, thin-film transistors, light-emitting elements, etc. are arranged in a plurality of subpixels (SP) of a display area (AA) on a substrate (SUB), a plurality of insulating layers may be formed on the substrate (SUB). In the following description, it is assumed that a buffer layer (BUF), a gate insulating layer (GI), a first interlayer insulating layer (INT1), a second interlayer insulating layer (INT2), a third interlayer insulating layer (INT3), a planarization layer (PLN), and a bank are arranged on the substrate (SUB), but the configuration of the display device (100) is exemplary and is not limited thereto.

[0065] A buffer layer (BUF) is disposed on a substrate (SUB). The buffer layer (BUF) can prevent moisture or impurities from penetrating through the substrate (SUB). The buffer layer (BUF) may be composed of, for example, a single layer or multiple layers of silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0066] A thin-film transistor comprising an active layer, a gate electrode, a source electrode, and a drain electrode may be disposed on a plurality of subpixels (SP) on a buffer layer (BUF), and a gate insulating layer (GI) may be disposed on the buffer layer (BUF) to insulate the active layer and the gate electrode. The gate insulating layer (GI) is an insulating layer for insulating the active layer and the gate electrode, and may be composed of a single layer or multiple layers of silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0067] A first interlayer insulating layer (INT1), a second interlayer insulating layer (INT2), and a third interlayer insulating layer (INT3) may be sequentially disposed on a gate insulating layer (GI). The first interlayer insulating layer (INT1), the second interlayer insulating layer (INT2), and the third interlayer insulating layer (INT3) may be disposed between each component of the thin-film transistor and a plurality of wires to insulate them. For example, the first interlayer insulating layer (INT1), the second interlayer insulating layer (INT2), and the third interlayer insulating layer (INT3) may be disposed between the gate electrode, the source electrode, the drain electrode, and the data wires of the thin-film transistor. Each of the first interlayer insulating layer (INT1), the second interlayer insulating layer (INT2), and the third interlayer insulating layer (INT3) may be composed of a single layer or multiple layers of inorganic materials such as silicon oxide (SiOx) or silicon nitride (SiNx), or may be composed of a single layer or multiple layers of organic materials such as polyimide or photoacryl, but is not limited thereto.

[0068] A planarization layer (PLN) is disposed on the third interlayer insulating layer (INT3). The planarization layer (PLN) is an insulating layer that planarizes the upper surface of the substrate (SUB). The planarization layer (PLN) may be made of an organic material and may be composed of, for example, a single layer or multiple layers of polyimide or photoacryl, but is not limited thereto.

[0069] Although not shown in the drawing, a light-emitting element including an anode, a light-emitting layer (EL), and a cathode (CD) may be disposed on a planarization layer (PLN) in a display area (AA).

[0070] An anode may be disposed on each of a plurality of subpixels (SP) on a planarization layer (PLN). The anode may be connected to a plurality of thin-film transistors and receive voltage. The anode may be formed from a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), but is not limited thereto. Additionally, if the display device (100) is configured in a top emission manner, a reflective layer may be further disposed on the anode to reflect light emitted from the light-emitting element onto the upper surface of the substrate (SUB). For example, the reflective layer may include a material with excellent reflectivity such as aluminum (Al) or silver (Ag), but is not limited thereto.

[0071] A bank may be placed between multiple subpixels (SP) on an anode. The bank is an insulating layer placed to separate multiple subpixels (SP) and may cover the edges of each anode of the multiple subpixels (SP). The bank may be formed of an organic material, and the bank (132) may be made of polyimide, acryl, or benzocyclobutene (BCB)-based resin, but is not limited thereto.

[0072] An emitting layer (EL) may be disposed on the anode and bank. The emitting layer (EL) may be an organic layer (EC2) for emitting light of a specific color. Additionally, the emitting layer (EL) may further include various layers such as a hole transport layer, a hole injection layer, a hole blocking layer, an electron injection layer, an electron blocking layer, and an electron transport layer. The emitting layer (EL) may be formed across the entire surface of the substrate (SUB) as shown in FIG. 4, or may be formed separately at each of a plurality of subpixels (SP).

[0073] A cathode (CD) is disposed on the light-emitting layer (EL). The cathode (CD) can be formed as a single layer across the entire surface of the substrate (SUB). The cathode (CD) can be formed in common across a plurality of subpixels (SP). The cathode (CD) can be formed, for example, with a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), a metal alloy such as MgAg, or an ytterbium (Yb) alloy, but is not limited thereto.

[0074] An encapsulation portion (EC) is disposed on the light-emitting element. The encapsulation portion (EC) is a sealing layer for protecting the light-emitting element from moisture, etc., penetrating from outside the display device (100). The encapsulation portion (EC) includes a first inorganic layer (EC1), an organic layer (EC2), and a second inorganic layer (EC3).

[0075] The first inorganic layer (EC1) is placed on the cathode (CD) to block moisture or oxygen from penetrating into the display device (100). The first inorganic layer (EC1) may be made of inorganic materials such as silicon nitride (SiNx), silicon oxynitride (SiNxOy), or aluminum oxide (AlyOz), but is not limited thereto.

[0076] The organic layer (EC2) is disposed on the first inorganic layer (EC1) to flatten the upper surface of the substrate (SUB) containing the first inorganic layer (EC1). The organic layer (EC2) can cover foreign matter or particles that may occur during the manufacturing process. The organic layer (EC2) may be composed of organic materials, for example, silicon oxycarbon (SiOxCz), acrylic or epoxy-based resins, but is not limited thereto.

[0077] The second inorganic layer (EC3) is disposed on the organic layer (EC2) and can prevent the penetration of moisture or oxygen, similar to the first inorganic layer (EC1). The second inorganic layer (EC3) and the first inorganic layer (EC1) can be formed to seal the organic layer (EC2). For example, the first inorganic layer (EC1) and the second inorganic layer (EC3) can extend outward from the organic layer (EC2) and come into contact with each other to seal the organic layer (EC2). The second inorganic layer (EC3) may be composed of inorganic materials such as silicon nitride (SiNx), silicon oxynitride (SiNxOy), or aluminum oxide (AlyOz), but is not limited thereto.

[0078] Meanwhile, a plurality of dams (DM) are arranged around the through hole (TH). At least some of the plurality of dams (DM) may be formed in a closed curve shape surrounding the through hole (TH). The plurality of dams (DM) can prevent the organic layer (EC2) of the sealing portion (EC) from overflowing toward the through hole (TH) and block external moisture from penetrating into the marked area (AA).

[0079] A plurality of dams (DM) include a first dam (DM1), a second dam (DM2), a third dam (DM3), a fourth dam (DM4), and a fifth dam (DM5). The first dam (DM1) is positioned closest to the through hole (TH), the fifth dam (DM5) is positioned closest to the display area (AA), and the third dam (DM3) is positioned between the first dam (DM1) and the fifth dam (DM5). Then, the second dam (DM2) is positioned between the first dam (DM1) and the third dam (DM3), and the fourth dam (DM4) is positioned between the third dam (DM3) and the fifth dam (DM5).

[0080] Each of the first dam (DM1), the third dam (DM3), and the fifth dam (DM5) may consist of multiple dams (DM) spaced apart at a certain distance. Although FIG. 4 depicts the first dam (DM1), the third dam (DM3), and the fifth dam (DM5) arranged in sets of three, they are not limited thereto.

[0081] A plurality of dams (DM) may be formed by patterning some of the plurality of insulating layers disposed on a substrate (SUB). For example, the first dam (DM1), the third dam (DM3), and the fifth dam (DM5) may include a first layer (INT3a) formed by patterning the third interlayer insulating layer (INT3) and a second layer (PLNa) formed by patterning the first flattening layer (PLN).

[0082] The first dam (DM1), the third dam (DM3), and the fifth dam (DM5) can prevent moisture from penetrating into the display area (AA) through the light-emitting layer (EL). For example, the light-emitting layer (EL), which is vulnerable to moisture penetration, is formed on the front surface of the substrate (SUB) and may be partially exposed through the through-hole (TH). The first dam (DM1), the third dam (DM3), and the fifth dam (DM5) can reduce moisture penetration through the light-emitting layer (EL) by disconnecting this light-emitting layer (EL).

[0083] At this time, in order to easily disconnect the light-emitting layer (EL), the first dam (DM1), the third dam (DM3), and the fifth dam (DM5) may each be configured such that the width of the first layer (INT3a) below the second layer (PLNa) is smaller than that of the second layer (PLNa). As the width of the first layer (INT3a), formed by patterning the third interlayer insulating layer (INT3), is configured to be smaller than the width of the second layer (PLNa), formed by patterning the flattening layer (PLN), the light-emitting layer (EL) may be disconnected at the first dam (DM1), the third dam (DM3), and the fifth dam (DM5). In this case, the cathode (CD), formed on the front surface of the substrate (SUB) in the same way as the light-emitting layer (EL), may also be disconnected at the first dam (DM1), the third dam (DM3), and the fifth dam (DM5) in a manner similar to the light-emitting layer (EL).

[0084] Meanwhile, the encapsulation portion (EC) can cover the light-emitting layer (EL) and the cathode (CD) that are disconnected from the dam (DM). For example, the first inorganic layer (EC1) and the second inorganic layer (EC3) can cover both the disconnected light-emitting layer (EL) and the cathode (CD). Therefore, even if moisture penetrates through the light-emitting layer (EL) exposed in the through hole (TH), the first dam (DM1), the third dam (DM3), the fifth dam (DM5), and the encapsulation portion (EC) can prevent the moisture from moving to the display area (AA).

[0085] The second dam (DM2) and the fourth dam (DM4) may be formed in a closed curve shape surrounding the through hole (TH). The second dam (DM2) and the fourth dam (DM4) may include a first layer (INT3a) formed by patterning the third interlayer insulation layer (INT3), a second layer (PLNa) formed by patterning the flattening layer (PLN), and a third layer (BKa) formed by patterning the bank.

[0086] The second dam (DM2) and the fourth dam (DM4) can prevent the organic layer (EC2) of the sealing portion (EC) from overflowing into the through hole (TH). The organic layer (EC2) can be formed up to the inside of the second dam (DM2). However, although FIG. 4 is illustrated as having the organic layer (EC2) formed up to the inside of the second dam (DM2), the organic layer (EC2) can be formed up to the inside of the fourth dam (DM4) and is not limited thereto.

[0087] Additionally, a first additional planarization layer (TPLN1) and a second additional planarization layer (TPLN2) may be further disposed on the encapsulation portion (EC). For example, when a touch portion is disposed on the encapsulation portion (EC), the first additional planarization layer (TPLN1) and the second additional planarization layer (TPLN2) may be further disposed to form a flat touch electrode and to insulate the touch electrodes from each other. The first additional planarization layer (TPLN1) may cover an area where a plurality of dams (DM) are formed from the through hole (TH), and the second additional planarization layer (TPLN2) may cover the entire surface of the substrate (SUB). However, the first additional planarization layer (TPLN1) and the second additional planarization layer (TPLN2) may be omitted depending on the design of the touch portion, and are not limited thereto.

[0088] However, the configuration and arrangement structure of the display panel (140) shown in FIG. 4 is exemplary and is not limited thereto.

[0089] Meanwhile, the interior of the display panel (140) is exposed through the through hole (TH). For example, the substrate (SUB), light-emitting layer (EL), cathode (CD), encapsulation portion (EC), first additional flattening layer (TPLN1), and second additional flattening layer (TPLN2) of the display panel (140) may be exposed through the through hole (TH). The substrate (SUB), encapsulation portion (EC), first additional flattening layer (TPLN1), and second additional flattening layer (TPLN2) exposed on the side through the through hole (TH) are made of an insulating material so that they do not affect the interior of the display panel (140) even when in contact with the conductive light-shielding member (170). On the other hand, the cathode (CD) and light-emitting layer (EL) exposed on the side in the through hole (TH) are not insulating materials, but are disconnected from the cathode (CD) and light-emitting layer (EL) of the display area (AA) by a plurality of dams (DM). Therefore, even if a conductive light-blocking member (170) comes into contact with the side of the cathode (CD) and light-emitting layer (EL), it does not affect the plurality of subpixels (SP) of the display area (AA). Accordingly, even if a conductive light-blocking member (170) is formed directly without forming a separate insulating layer on the inner side of the through hole (TH), it may not affect the operation inside the display panel (140).

[0090] In a display device (100) according to one embodiment of the present invention, a conductive light-blocking member (170) is formed inside a through hole (TH) in which an optical component is placed, thereby preventing light from the display panel (140) from being transmitted to the optical component. Specifically, the conductive light-blocking member (170) is positioned to cover the inner surface of the through hole (TH), thereby blocking light emitted from a plurality of sub-pixels (SP) from heading into the through hole (TH). If light from a plurality of sub-pixels (SP) is transmitted into the through hole (TH), it interferes with the recognition of light from outside the optical component, which may reduce the reliability of the optical component. That is, light from a plurality of sub-pixels (SP) may act as noise. Accordingly, in a display device (100) according to one embodiment of the present invention, a conductive light-blocking member (170) is placed inside the through hole (TH) to prevent light leakage and improve the reliability of the optical component.

[0091] In a display device (100) according to one embodiment of the present invention, static electricity generated in a cover window (110) can be discharged using a conductive light-blocking member (170). The cover window (110) is configured to be exposed to the outside of the display device (100), and static electricity can easily be generated by friction with the outside. However, if static electricity generated in the cover window (110) flows into the interior of the display panel (140), the internal components of the display panel (140) may be damaged, and this may lead to a defect in the display device (100). At this time, the conductive light-blocking member (170) is made of an electrically conductive material and can discharge static electricity generated in the cover window (110) to a metal plate (160). The metal plate (160) is configured to be electrically grounded to discharge static electricity. The conductive light-blocking member (170) can be connected between the metal plate (160) and the cover window (110) to form a path through which static electricity generated from the cover window (110) is discharged. Accordingly, in a display device (100) according to one embodiment of the present invention, a conductive light-blocking member (170) connecting a cover window (110) and a metal plate (160) is arranged to discharge static electricity from the cover window (110) and minimize the inflow of static electricity into the display panel (140).

[0092] In a display device (100) according to one embodiment of the present invention, the process can be simplified and manufacturing costs can be reduced by using a conductive light-shielding member (170) that integrates light leakage prevention and electrostatic discharge functions. Previously, the process of forming light-shielding ink to prevent light leakage from the through hole (TH) and the process of attaching a conductive tape inside the display device for electrostatic discharge were performed separately. On the other hand, in a display device (100) according to one embodiment of the present invention, the light-shielding member that prevents light leakage from the through hole (TH) is conductive and can also perform an electrostatic discharge function. Accordingly, the process of attaching the conductive tape can be eliminated and manufacturing costs can be reduced. Therefore, in a display device (100) according to one embodiment of the present invention, some processes can be eliminated and manufacturing costs can be reduced by using a conductive light-shielding member (170).

[0093] Meanwhile, when forming the conductive light-shielding member (170), if a defect occurs where the conductive light-shielding member (170) is not applied to some areas, light leakage may occur, causing noise in the optical components. Accordingly, in the display device (100) according to one embodiment of the present invention, the defect of the conductive light-shielding member (170) can be inspected together during the image quality inspection of the display device (100). Hereinafter, a method for inspecting the conductive light-shielding member (170) in the display device (100) according to one embodiment of the present invention will be described with reference to FIGS. 5 to 7.

[0094] FIG. 5 is a perspective view of a jig on which a display device is mounted during the manufacture of a display device according to an embodiment of the present invention. FIG. 6 is a schematic cross-sectional view for explaining a method for inspecting a conductive light-shielding member during the manufacture of a display device according to an embodiment of the present invention. FIG. 7 is a drawing for explaining the inspection results of a conductive light-shielding member during the manufacture of a display device according to an embodiment of the present invention.

[0095] Referring to FIG. 5, the jig is configured such that the display device (100) is placed thereon during an image quality inspection of the display device (100). With the display device (100) placed on the jig, the display device (100) can be driven to inspect for defects such as dark spots or bright spots. For example, while the display device (100) is in operation, the display device (100) can be inspected using a vision method to detect image quality defects, such as dark spots or bright spots.

[0096] Referring to FIG. 6, a convex lens (CL) is formed in the part corresponding to the through hole (TH) in the jig so that the conductive light-blocking member (170) can be inspected together during image quality inspection. Specifically, during image quality inspection, the display device (100) is driven so that light emitted from a plurality of sub-pixels (SP) can be displayed on the front of the display device (100). The light emitted from the plurality of sub-pixels (SP) may proceed not only toward the front of the display device (100) but also toward the side or back of the display device (100), and some of it may proceed toward the through hole (TH) inside the display device (100). If there is an uncoated area (X) where the conductive light-blocking member (170) is not coated, light from the plurality of sub-pixels (SP) can proceed into the through hole (TH) through the uncoated area (X). And some of the light that travels into the through hole (TH) can be reflected by the convex lens (CL) and directed toward the front of the display device (100), and can be detected by a camera that photographs the display device (100).

[0097] For example, referring to FIG. 7(a), when the conductive light-blocking member (170) is applied to the entire through hole (TH) and there is no unapplied area (X), light emitted from a plurality of subpixels (SP) cannot proceed into the through hole (TH). Therefore, when the conductive light-blocking member (170) is formed normally, it can be confirmed that light cannot be detected in the through hole (TH) portion during the image quality inspection of the display device (100), and the portion corresponding to the through hole (TH) is displayed only in black.

[0098] For example, referring to FIG. 7(b) and FIG. 7(c), when a conductive light-blocking member (170) as shown in FIG. 6 is not applied to a portion of the through hole (TH) and an unapplied area (X) is created, light emitted from a plurality of subpixels (SP) can proceed into the through hole (TH) through the unapplied area (X). And since the light that has proceeded into the through hole (TH) is reflected by a convex lens (CL) positioned corresponding to the through hole (TH), light can be detected in the through hole (TH) portion during image quality inspection. For example, if an uncoated area (X) occurs throughout the entire through hole (TH), a light leakage area formed throughout can be identified as shown in FIG. 7(b), and if an uncoated area (X) occurs only in a part of the through hole (TH), a light leakage area can be identified only in a part as shown in FIG. 7(c). Therefore, if the conductive light-blocking member (170) is formed abnormally, light can be detected in the through hole (TH) portion during the image quality inspection of the display device (100), and it can be confirmed that a part of the portion corresponding to the through hole (TH) is displayed as white.

[0099] Accordingly, in a display device (100) according to one embodiment of the present invention, a convex lens (CL) is formed in a jig (JIG) to correspond to a through hole (TH), thereby allowing for simultaneous inspection of image quality and defect inspection of a conductive light-blocking member (170), and simplifying the process. Previously, the inspection of the conductive light-blocking member (170) and the inspection of image quality were performed separately. For example, during the image quality inspection, the front of the display device (100) was positioned so that it faced upward, and the inspection was performed. However, during the inspection of the conductive light-blocking member (170), the back of the display device (100) was positioned in a separate device so that it faced upward, and the display device (100) was driven to inspect whether light leakage occurred. In contrast, in a display device (100) according to one embodiment of the present invention, a convex lens (CL) is formed on a jig (JIG) on which the display device (100) is mounted during image quality inspection, and light reflected from the convex lens (CL) is detected when light leakage occurs, thereby detecting a defect in the non-application of the conductive light-blocking member (170). Accordingly, in a display device (100) according to one embodiment of the present invention, a defect in the non-application of the conductive light-blocking member (170) can be detected together during image quality inspection, thereby simplifying the process and reducing manufacturing costs.

[0100] FIG. 8 is a plan view of a display device according to another embodiment of the present invention. FIG. 9 is a cross-sectional view of a display device according to another embodiment of the present invention. The display device (800) of FIG. 8 and FIG. 9 differs from the display device (100) of FIG. 1 to FIG. 4 only in the camera area (CA), and other configurations are substantially the same, so a redundant description is omitted.

[0101] Referring to FIG. 8, the display panel (840) includes a display area (AA), a non-display area (NA), and a camera area (CA). The camera area (CA) may be positioned outside the display area (AA). The camera area (CA) includes a notch (NC) formed by removing a central portion of the top of the display area (AA). Accordingly, the top portion of the display area (AA) may be positioned spaced apart from each other with the camera area (CA) having the notch (NC) formed therein in between.

[0102] Referring to FIG. 9, a notch (NC) is formed in the remaining components excluding the cover window (110). The notch (NC) can be formed by removing the adhesive layer (820), polarizer (830), display panel (840), backplate (850), and metal plate (860) corresponding to the camera area (CA). The notch (NC) can be a groove formed by removing the adhesive layer (820), polarizer (830), display panel (840), backplate (850), and metal plate (860). An optical component can be placed in the notch (NC), which is an empty space formed by removing the adhesive layer (820), polarizer (830), display panel (840), backplate (850), and metal plate (860).

[0103] And, in order to prevent light from a plurality of subpixels (SP) from flowing toward the notch (NC) towards the notch (NC), a conductive light-blocking member (870) is formed to cover the notch (NC). The conductive light-blocking member (870) may be positioned to cover the side of the adhesive layer (820) exposed at the notch (NC), the side of the polarizing plate (830), the side of the display panel (840), the side of the backplate (850), and the side of the metal plate (860).

[0104] For convenience of explanation, the notch (NC) formed in the adhesive layer (820), polarizing plate (830), display panel (840), and backplate (850) will be referred to as the first notch (NC1), and the notch (NC) formed in the metal plate (860) will be referred to as the second notch (NC2); however, the first notch (NC1) and the second notch (NC2) are exemplary and are not limited thereto.

[0105] For example, referring to FIG. 9, the first notch (NC1) is a portion from which the adhesive layer (820), polarizer (830), display panel (840), and backplate (850) have been removed, and may be the space between the side of the adhesive layer (820), the side of the polarizer (830), the side of the display panel (840), and the side of the backplate (850) from the end of the cover window (110). The first notch (NC1) may be positioned along the adhesive layer (820), polarizer (830), display panel (840), and backplate (850). And the second notch (NC2) is a portion from which the metal plate (860) has been removed, and may be the space between the side of the metal plate (860) from the end of the cover window (110).

[0106] A first notch (NC1) can be formed at once on an adhesive layer (820), a polarizer (830), a display panel (840), and a backplate (850), and a metal plate (860) having a second notch (NC2) can be attached. In this case, the size of the second notch (NC2) may be larger than that of the first notch (NC1).

[0107] However, although FIG. 9 shows that the sizes of the first notch (NC1) and the second notch (NC2) are different, the sizes of the first notch (NC1) and the second notch (NC2) may be configured to be the same by forming the notch (NC) in the adhesive layer (820), polarizer (830), display panel (840), backplate (850), and metal plate (860) at once, and are not limited thereto.

[0108] The conductive light-shielding member (870) can cover the side of the adhesive layer (820) exposed at the first notch (NC1), the side of the polarizer (830), the side of the display panel (840), the side of the backplate (850), and the side of the metal plate (860) exposed at the second notch (NC2). Specifically, the conductive light-shielding member (870) can cover the boundary portion between the side of the adhesive layer (820) and the back surface of the cover window (110) at the first notch (NC1), the side of the adhesive layer (820), the side of the polarizer (830), the side of the display panel (840), and the side of the backplate (850). Additionally, the conductive light-shielding member (870) can cover the boundary portion between the back surface of the backplate (850) and the side of the metal plate (860) at the second notch (NC2) and the side of the metal plate (860). And the conductive light-blocking member (870) can overlap with a part of the metal plate (860).

[0109] Meanwhile, the conductive light-blocking member (870) is positioned only on the side of the metal plate (860) at the second notch (NC2) and is not positioned on the back of the metal plate (860). The end of the conductive light-blocking member (870) may not be positioned on the back of the metal plate (860). If the conductive light-blocking member (870) is positioned on the back of the metal plate (860), the circuit board for driving the optical component and the conductive light-blocking member (870) may interfere with each other, causing a short circuit defect, or interference may occur with the frame or other components. Therefore, the conductive light-blocking member (870) may be formed only from the second notch (NC2) to the side of the metal plate (860).

[0110] In a display device (800) according to another embodiment of the present invention, a conductive light-blocking member (870) is formed in a notch portion (NC) corresponding to a camera area (CA) to prevent light leakage and simultaneously discharge static electricity from the cover window (110). Specifically, a camera area (CA) in which a camera is placed can be formed by cutting a portion of the adhesive layer (820), polarizer (830), display panel (840), backplate (850), and metal plate (860) below the cover window (110) to form a notch portion (NC). At this time, in order to block light emitted from a plurality of subpixels (SP) of the display panel (840) from heading toward the notch portion (NC), a conductive light-blocking member (870) covering the side of the adhesive layer (820), polarizer (830), display panel (840), backplate (850), and metal plate (860) can be formed in the notch portion (NC). At this time, the conductive light-blocking member (870) can be formed from a conductive material to discharge static electricity generated in the cover window (110) toward the metal plate (860). Accordingly, in a display device (800) according to another embodiment of the present invention, the conductive light-blocking member (870) is formed in the notch portion (NC) to block light from entering the display panel (840) into the camera area (CA), while simultaneously discharging static electricity generated in the cover window (110), thereby improving the reliability of the display device (800).

[0111] A display device according to embodiments of the present invention can be described as follows.

[0112] A display device according to one embodiment of the present invention comprises: a display panel including a display area having a plurality of subpixels arranged thereon and a camera area adjacent to the display area and having a first hole arranged thereon; a first plate including a second hole arranged on the back surface of the display panel and overlapping with the first hole; a front member arranged on the upper surface of the display panel; and a light-blocking member covering the back surface of the front member exposed at the first hole, the inner surface of the first hole, and the inner surface of the second hole.

[0113] According to another feature of the present invention, the end of the light-blocking member may be disposed on the side of the first plate exposed in the second hole.

[0114] According to another feature of the present invention, the invention further comprises an adhesive layer disposed between a display panel and a front member, a polarizing plate disposed between the adhesive layer and the display panel, and a second plate disposed between the display panel and a first plate, wherein a first hole may be disposed along the adhesive layer, the polarizing plate, the display panel, and the second plate.

[0115] According to another feature of the present invention, the diameter of the first hole is smaller than the diameter of the second hole, and the light-shielding member can cover the side of the adhesive layer exposed in the first hole, the side of the polarizing plate, the side of the display panel, and the side of the second plate, as well as the back surface of the second plate and the side of the first plate exposed in the second hole.
