[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0045036, filed on April 17, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] Aspects of some exemplary embodiments of the present disclosure relate to a display device. Background Art

[0004] With the development of multimedia technology, display devices are becoming more and more important. Therefore, various display devices, such as liquid crystal display (LCD) devices and organic light emitting diode (OLED) display devices, are currently being developed.

[0005] There is an area in which a driver IC or other printed circuit is located on the outer periphery of the glass substrate of the display device. This area may be referred to as a frame, which is a non-display area where no image is displayed. For a spliced ​​display device in which a plurality of display devices are arranged in a grid pattern or a matrix pattern to form a large screen, the display devices are connected to each other. Therefore, a non-display area is formed where two frames of adjacent display devices are arranged together. Such a non-display area will be recognized by the viewer, and thus the quality of the displayed image will be degraded.

[0058] Aspects of some exemplary embodiments of the present invention will now be more fully described below with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. However, the present invention may be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thorough and more complete, and the scope of the present invention will be more fully conveyed to those skilled in the art.

[0059] It will also be understood that when a layer is referred to as being 'on' another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. Throughout the specification, the same reference numerals refer to the same components.

[0060] Hereinafter, aspects of some exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0061] Figure 1 2 is a view showing a spliced ​​display device. Figure 2 It is schematically shown Figure 1 An exploded perspective view of a display device. Figure 3 is a perspective view schematically illustrating a display panel and a printed circuit board coupled thereto according to some exemplary embodiments of the present disclosure. Figure 42 is a view for illustrating interconnections of a display device according to some exemplary embodiments of the present disclosure. Figure 5 It is along Figure 3 A cross-sectional view taken along line II'.

[0062] Unless otherwise specified, as used herein, "above" and "upper surface" in the thickness direction refer to the side of the display device 1 on which an image is displayed or the side indicated by the arrow in the third direction DR3, whereas "below" and "lower surface" refer to the opposite side of the display device 1 opposite to the side on which an image is displayed or the opposite side in the third direction DR3. In addition, "upper side", "lower side", "left side" and "right side" in a plane are defined when the display surface is observed from the top. For example, "left side" refers to the opposite side opposite to the side indicated by the arrow in the second direction DR2, "right side" refers to the side indicated by the arrow in the second direction DR2, "upper side" refers to the side indicated by the arrow in the first direction DR1, and "lower side" refers to the opposite side opposite to the side indicated by the arrow in the first direction DR1.

[0063] The display device 1 may be a self-luminous display device, such as an organic light-emitting display device, a quantum dot light-emitting display device, a micro-LED display device, and a nano-LED display device. Alternatively, the display device 1 may be a non-self-luminous display device, such as an electrophoretic display device and an electrowetting display device. In the following description, for the convenience of illustration, a liquid crystal display device including a liquid crystal layer is described as an example of the display device 1.

[0064] In some exemplary embodiments, the display device 1 may be used in large electronic devices such as televisions and electronic boards, and small and medium-sized electronic devices such as personal computers, laptop computers, vehicle navigation devices, and cameras, etc. In addition, the display device 1 may be used in tablet PCs, smart phones, personal digital assistants (PDAs), portable multimedia players (PMPs), game devices, watch-type electronic devices, etc. The electronic devices listed above are merely illustrative, and the display device 1 may be used by other electronic devices.

[0065] refer to Figure 1 , the spliced ​​display device TD may include a plurality of display devices 1. According to some exemplary embodiments, the plurality of display devices 1 may be arranged in a grid pattern, but the present disclosure is not limited thereto. The display devices 1 may be connected in a first direction DR1 or in a second direction DR2, or may be connected in a special pattern. The display devices 1 may have the same size, but the present disclosure is not limited thereto. The display devices 1 may have different sizes.

[0066] According to some exemplary embodiments, the plurality of display devices 1 included in the spliced ​​display device TD may have a rectangular shape including a longer side and a shorter side. The longer side or the shorter side of each of the plurality of display devices 1 may be connected to the longer side or the shorter side of an adjacent display device 1 among the display devices 1. Some of the display devices 1 may form one side of the spliced ​​display device TD, some of the display devices 1 may be positioned at a corner of the spliced ​​display device TD to form two adjacent sides, and some of the display devices 1 may be positioned on the inner side of the spliced ​​display device TD and surrounded by other display devices 1 among the display devices 1.

[0067] Each of the display devices 1 may include a display area DA and a non-display area NDA. The display area DA is where an image is displayed. The non-display area NDA is where an image is not displayed, i.e., a frame of the display device 1, and the non-display area NDA may be positioned around the display area DA. The non-display area NDA may surround the display area DA, but the present disclosure is not limited thereto. Different display devices 1 may have non-display areas NDA of different shapes depending on their locations. Alternatively, the display devices 1 may have non-display areas NDA of the same shape.

[0068] The spliced ​​display device TD may generally have a planar shape, but the present disclosure is not limited thereto. The spliced ​​display device TD may have a three-dimensional shape to impart a three-dimensional effect. When the spliced ​​display device TD has a three-dimensional shape, each of the display devices 1 included in the spliced ​​display device TD may have a curved shape and may be connected to each other in a planar shape or at a predetermined angle, so that the spliced ​​display device TD may be formed into a three-dimensional shape.

[0069] The frames defined as non-display areas NDA of multiple display devices 1 may be directly connected to each other. Alternatively, they may be connected to each other by a connecting member. In this way, because the display devices 1 are connected to each other in the spliced ​​display device TD, the two frames of adjacent display devices 1 are arranged together at the connecting portion. Therefore, each of the display devices 1 needs to have a thin frame. For this purpose, it is conceivable that the contact pads of the flexible circuit board are connected to the side surface of each of the display devices 1. This will be described in more detail below.

[0070] Hereinafter, an exemplary embodiment of a display device 1 will be described in detail, which may be applied as one of the display devices 1 of the tiled display apparatus TD or may be used alone.

[0071] refer to Figures 2 to 5 , each of the display devices 1 may include a display panel DPN, a backlight unit BLU, a bottom cover BC, a middle frame MC, and a cover member TC, wherein the backlight unit BLU is below the display panel DPN, and the bottom cover BC accommodates and fixes the display panel DPN and the backlight unit BLU.

[0072] The display panel DPN may include a first substrate 100, a liquid crystal layer 200, and a second substrate 300. According to some exemplary embodiments, Figure 3 As shown in , the display panel DPN may further include a flexible circuit board SFPC1 attached to one side surface of the display panel DPN and a printed circuit board SPCB (hereinafter, also referred to as a driving circuit board SPCB) connected to the flexible circuit board SFPC1.

[0073] Each of the first substrate 100 and the second substrate 300 may have a rectangular shape having a longer side in a first direction DR1 and a shorter side in a second direction DR2 perpendicular to the first direction DR1. However, it is understood that the shapes of the first substrate 100 and the second substrate 300 are not limited thereto. In some embodiments, the first substrate 100 and the second substrate 300 may have a curved portion.

[0074] The display panel DPN may include a display area DA that displays an image and a non-display area NDA that does not display an image. The display area DA and the non-display area NDA of the display panel DPN may be respectively aligned with the display area DA and the non-display area NDA of the display device 1. According to some exemplary embodiments, the display device 1 may further include a window member on the second substrate 300 that covers the display panel DPN and transmits the image to the outside.

[0075] The first substrate 100 and the second substrate 300 may have different areas. For example, the area of ​​the first substrate 100 may be smaller than the area of ​​the second substrate 300. The areas of the first substrate 100 and the second substrate 300 will be discussed in more detail below.

[0076] The first substrate 100 may include a plurality of pixels SPX. According to some exemplary embodiments, the plurality of pixels SPX may be arranged in a matrix. However, it is to be understood that the present disclosure is not limited thereto. A plurality of gate lines SGL1 to SGLm and a plurality of data lines SDL1 to SDLn may be positioned along the boundaries of the pixels SPX, where m and n are natural numbers. The gate lines SGL1 to SGLm may be used as selection lines for selecting among the plurality of pixels SPX.

[0077] Although for the convenience of illustration Figure 2 Only one pixel SPX is depicted in FIG. 1 , but it should be understood that, in practice, a plurality of pixels SPX may be defined on the first substrate 100. In each of the plurality of pixels SPX, a pixel electrode defining the pixel SPX may be arranged.

[0078] The gate lines SGL1 to SGLm and the data lines SDL1 to SDLn may be insulated from each other and cross each other. The gate lines SGL1 to SGLm may extend in a first direction DR1 and may be electrically connected to the gate driver SGD. The data lines SDL1 to SDLn may extend in a second direction DR2 and may be connected to the gate driver SGD. Figure 3 The data drive SDD shown in FIG.

[0079] The pixels SPX may be electrically connected to the gate lines SGL1 to SGLm and the data lines SDL1 to SDLn crossing each other. The pixels SPX may be arranged in a matrix, but are not limited thereto.

[0080] For example, the gate driver SGD may be disposed at a predetermined position adjacent to at least one of the shorter sides of the first substrate 100. However, it is to be understood that the position of the gate driver SGD is not limited thereto.

[0081] For example, the gate driver SGD may be formed during a process of manufacturing a transistor for driving the pixel SPX and may be mounted on the first substrate 100 in the form of an amorphous silicon TFT gate driver circuit (ASG) or an oxide silicon TFT gate driver circuit (OSG).

[0082] However, it is to be understood that the present disclosure is not limited thereto. In some embodiments, the gate driver SGD may be formed of a plurality of driver chips, may be mounted on a flexible driving circuit board, and may be mounted on the first substrate 100 by using a tape carrier package (TCP) technology. The gate driver SGD may be formed of a plurality of driver chips, and may be mounted on the first substrate 100 by using a chip on glass (COG) technology.

[0083] like Figure 3 As shown in , the data driver SDD may include a source driver chip SDIC1. The data driver SDD may include a single source driver chip SDIC1 or more than one source driver chip SDIC1. Figure 3 In the example shown in , five source driver chips SDIC1 are placed, but the number of source driver chips SDIC1 is not limited thereto.

[0084] The printed circuit board SPCB may include, for example, a timing controller. The timing controller may be mounted on the printed circuit board SPCB in the form of an integrated circuit chip and electrically connected to the gate driver SGD and the data driver SDD. The timing controller may output a gate control signal, a data control signal, and image data.

[0085] The gate driver SGD may receive a gate control signal from the timing controller. The gate driver SGD may generate a gate signal in response to the gate control signal and sequentially output the generated gate signal. The gate signal may be applied to the pixels SPX row by row via the gate lines SGL1 to SGLm. Therefore, the pixels SPX may be driven row by row.

[0086] The data driver SDD may receive image data and a data control signal from the timing controller. The data driver SDD may generate an analog data voltage corresponding to the image data in response to the data control signal and output the analog data voltage. The data voltage may be provided to the pixel SPX through the data lines SDL1 to SDLn.

[0087] The pixels SPX may receive data voltages through the data lines SDL1 to SDLn in response to gate signals provided through the gate lines SGL1 to SGLm. The pixels SPX may display grayscales corresponding to the data voltages, thereby controlling transmittance of a region in which each pixel SPX is arranged.

[0088] Although the flexible circuit board SFPC1 is connected to the longer side of the first substrate 100 in the example shown in the drawings, the exemplary embodiments of the present disclosure are not limited thereto. The position where the first substrate 100 and the flexible circuit board SFPC1 are connected may vary as needed. For example, the flexible circuit board SFPC1 may be arranged adjacent to the shorter side of the first substrate 100. In addition, the flexible circuit board SFPC1 may be arranged adjacent to the two longer sides of the first substrate 100. In addition, the flexible circuit board SFPC1 may be arranged on the two shorter sides of the first substrate 100, or may be arranged on the longer side and the shorter side.

[0089] like Figure 5 As shown in , each of the flexible circuit boards SFPC1 may include a first contact pad CP1. Each of the source driver chips SDIC1 may be electrically connected to the first contact pad CP1 of a corresponding one of the flexible circuit boards SFPC1. The first contact pad CP1 of each of the flexible circuit boards SFPC1 may be electrically connected to the connection pad 130 arranged on the side surface of the first substrate 100 through the adhesive film 400.

[0090] like Figure 4 As shown in FIG. 1 , the interconnection 115 may be arranged on the first substrate 100. As shown in the drawings, one end of the interconnections 115a, 115b, 115c, 115d, and 115e may be electrically connected to a plurality of data lines SDLr to SDL(r+4), respectively, where r is a natural number. Figure 5As shown in FIG. 1 , the other ends of the interconnections 115a, 115b, 115c, 115d, and 115e may be respectively connected to the connection pads 130. Therefore, the connection pads 130 may be respectively electrically connected to the plurality of data lines SDLr to SDL(r+4).

[0091] The gate line SGLr may cross the plurality of data lines SDLr to SDL(r+4). A plurality of pixels CPXr to CPX(r+4) may be electrically connected to the gate line SGLr.

[0092] Although only five interconnects 115a, 115b, 115c, 115d, and 115e are shown in the drawings, this is for the sake of understanding. In practice, the number of interconnects 115a, 115b, 115c, 115d, and 115e electrically connected to the data lines SDLr to SDL(r+4) may be greater than or less than five.

[0093] Although the interconnection 115 is electrically connected to the data lines SDLr to SDL(r+4) in the above description, the exemplary embodiments of the present disclosure are not limited thereto. According to modifications of the present disclosure, the interconnection 115 and the connection pad 130 may be arranged in a similar manner and may be connected to a plurality of gate lines SGL1 to SGLm (see Figure 2 ) or other lines. Hereinafter, the electrical connection of the data lines SDLr to SDL(r+4) will be described.

[0094] The interconnections 115 a to 115 e may include, for example, copper (Cu), but the material of the interconnections 115 a to 115 e is not limited thereto.

[0095] like Figure 5 As shown in FIG. 1 , the source driver chip SDIC1 mounted on the flexible circuit board SFPC1 may generate a data voltage for driving the pixels CPXr to CPX(r+4) electrically connected thereto through the connection pads 130. The data voltage thus generated may be transmitted to the data lines SDLr to SDL(r+4) through the connection pads 130.

[0096] The flexible circuit board SFPC1 may include first contact pads CP1, respectively. The source driver chip SDIC1 may be electrically connected to the first contact pads CP1 of the flexible circuit board SFPC1. The first contact pads CP1 of the flexible circuit board SFPC1 may be electrically connected to the connection pads 130 arranged on the side surface of the first substrate 100 through the adhesive film 400. For example, the first substrate 100 is shorter than the second substrate 300 by a first distance d1 in the second direction DR2. Therefore, the connection pads 130 connected to the interconnect 115 are arranged on the side surface of the first substrate 100 and arranged below the second substrate 300. The first distance d1 may be in the range of, but not limited to, from 0.3 mm to 0.5 mm. In this way, the connection pads 130 are arranged on the side surface of the first substrate 100 and arranged below the second substrate 300, so that the border of each of the display devices 1 at the connection portion can be further reduced to realize the spliced ​​display device TD.

[0097] The connection pads 130 may be attached to the flexible circuit board SFPC1 through the adhesive film 400. For example, the connection pads 130 may be electrically connected to the first contact pads CP1 of the flexible circuit board SFPC1 through an outer wire bonding (OLB) technique using the adhesive film 400.

[0098] According to some exemplary embodiments, the adhesive film 400 may be disposed over the entire connection pad 130, but the present disclosure is not limited thereto. In some exemplary embodiments, the adhesive film 400 may cover a portion of the connection pad 130 while exposing other portions of the connection pad 130. The connection pad 130 may be made of, but not limited to, aluminum (Al), silver (Ag), or the like.

[0099] In some exemplary embodiments, the adhesive film 400 may include an anisotropic conductive film (ACF). When the adhesive film 400 is an anisotropic conductive film, only the portion of the adhesive film 400 that contacts the connection pad 130 and the first contact pad CP1 of the flexible circuit board SFPC1 may have conductivity, thereby electrically connecting the connection pad 130 to the first contact pad CP1 of the flexible circuit board SFPC1. However, it is to be understood that the present disclosure is not limited thereto. In some embodiments, the adhesive film 400 may be removed. For example, the connection pad 130 may contact the first contact pad CP1 and be electrically connected to the first contact pad CP1. In such a case, the connection pad 130 may be directly connected to the first contact pad CP1 by ultrasonic welding, fusion welding, etc. In addition, since the connection pad 130 is arranged on the side surface of the first substrate 100 and arranged below the second substrate 300, the flexible circuit board SFPC1 connected to the connection pad 130 is also arranged on the side surface of the first substrate 100 and arranged below the second substrate 300.

[0100] The driving circuit board SPCB may be electrically connected to the flexible circuit board SFPC1. Specifically, the flexible circuit board SFPC1 may be electrically connected to the driving circuit board SPCB by electrically connecting the second contact pads CP2 of the flexible circuit board SFPC1 with the third contact pads CP3 of the driving circuit board SPCB.

[0101] Therefore, the source driver chip SDIC1 may also be electrically connected to the driving circuit board SPCB.

[0102] In some exemplary embodiments, the flexible circuit board SFPC1 may be provided in the form of a flexible printed circuit board. Specifically, the flexible circuit board SFPC1 may be implemented as a chip on film (COF). Therefore, the data driver SDD may be connected to the first substrate 100 and the driving circuit board SPCB by a tape carrier package (TCP) technology, and the flexible circuit board SFPC1 may be bent toward the back surface of the first substrate 100 so that the printed circuit board SPCB may be positioned below the middle frame MC.

[0103] like Figure 5 As shown in FIG. 1 , the connection pad 130 may be electrically connected to the interconnection 115 disposed on the first substrate 100. As described above, the connection pad 130 may be electrically connected to the interconnection 115, and the interconnection 115 may extend inside the first substrate 100 (eg, in the second direction DR2) to be electrically connected to the pixel SPX.

[0104] On both sides of the display panel DPN, a first substrate 100 and a second substrate 300 opposite to the first substrate 100 may be disposed.

[0105] Each of the first substrate 100 and the second substrate 300 may be a rigid substrate made of glass, quartz, etc., or a flexible substrate made of polyimide or other polymer resins. When a polyimide substrate is used as the first substrate 100 and the second substrate 300, the display panel DPN may be bent, curved, folded, or rolled, so that the display panel DPN may be implemented in a variety of forms.

[0106] As described above, the interconnection 115 disposed on the first substrate 100 may be electrically connected to the plurality of data lines SDLr to SDL(r+4) and the plurality of gate lines SGL1 to SGLm (see Figure 2 ).

[0107] like Figure 5 As shown in FIG. 1 , a spacer CS may be disposed between the first substrate 100 and the second substrate 300. The spacer CS may be disposed along edges of the first substrate 100 and the second substrate 300 to prevent leakage of the liquid crystal layer 200 between the two substrates 100 and 300.

[0108] The spacer CS may include a first spacer CS1 in contact with the first substrate 100 and the interconnect 115 and a second spacer CS2 in contact with the second substrate 300. In some exemplary embodiments, the first spacer CS1 may include a blue colorant. For example, the first spacer CS1 may be made of a blue photoresist. However, it is to be understood that this is merely illustrative. When the first spacer CS1 includes a blue colorant, there is an advantage of being able to more effectively block light leakage through the side surface.

[0109] According to some exemplary embodiments, a common electrode for applying an electric field to the liquid crystal layer 200 together with a pixel electrode of the first substrate 100 may be disposed on the second substrate 300 , but the present disclosure is not limited thereto.

[0110] According to some exemplary embodiments, a first polarization member and a second polarization member for selectively transmitting only specific light may be placed in the display panel DPN. For example, the first polarization member may be arranged between the backlight unit BLU and the first substrate 100, and the second polarization member may be arranged on the top surface of the second substrate 300. However, it is to be understood that this is merely illustrative.

[0111] The backlight unit BLU may generate light and may provide the generated light to the first substrate 100, the liquid crystal layer 200, and the second substrate 300. The display panel DPN including the first substrate 100, the liquid crystal layer 200, and the second substrate 300 may generate an image using the light provided from the backlight unit BLU and may provide the image to the outside. Figure 2 In the example shown in , a direct-type backlight unit BLU is adopted. However, it should be understood that the present disclosure is not limited thereto. In some exemplary embodiments, an edge-type backlight unit BLU may be adopted.

[0112] In some exemplary embodiments, the backlight unit BLU may include an optical member LM and a light source LS. For example, the optical member LM may include a diffuser, a condenser, and a protective sheet. The diffuser is used to diffuse incident light. The condenser is used to increase the brightness of diffused light. The protective sheet may protect the condenser and may ensure a viewing angle. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, the optical member LM may include only some of the diffuser, the condenser, and the protective sheet. In some exemplary embodiments, in addition to the diffuser, the condenser, and the protective sheet, the optical member LM may also include additional optical sheets.

[0113] In some exemplary embodiments, the light source LS is accommodated in the bottom cover BC. For example, a plurality of light sources LS are arranged on the bottom BC1 of the bottom cover BC. Light emitted from the light source LS may be incident on the optical member LM and the display panel DPN. In addition, according to some exemplary embodiments, in order to improve the efficiency of output light, a reflective plate may be further arranged between the light source LS and the bottom BC1.

[0114] Each of the light sources LS may be at least one of a cold cathode fluorescent lamp (CCFL), a flat fluorescent lamp (FFL), and a light emitting diode (LED).

[0115] However, it is to be understood that this is merely illustrative. In some exemplary embodiments, the display device 1 may be as shown in FIG. Fig.33 , as shown in . In such a case, an organic light-emitting layer EML and / or a thin film encapsulation layer TFEL may be arranged between the first substrate 100 and the second substrate 300. For example, the organic light-emitting layer EML may include a pixel and a dam for defining the pixel, wherein the pixel includes a first electrode, an emission layer, and a second electrode. The emission layer may be an organic emission layer containing an organic material. Then, the emission layer may include a hole transport layer, an organic light-emitting layer, and an electron transport layer. When a voltage is applied to the first electrode and a cathode voltage is applied to the second electrode through a thin film transistor, holes and electrons move to the organic light-emitting layer through the hole transport layer and the electron transport layer, respectively, so that they combine in the organic light-emitting layer to emit light.

[0116] The thin film encapsulation layer TFEL is used to prevent oxygen or moisture from penetrating into the organic light emitting layer EML. For this purpose, the thin film encapsulation layer TFEL may include at least one inorganic layer. The inorganic layer may be, but is not limited to, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. In addition, the thin film encapsulation layer TFEL protects the organic light emitting layer EML from foreign substances such as dust. For this purpose, the thin film encapsulation layer TFEL may include at least one organic layer. The organic layer may be formed of, but is not limited to, acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin.

[0117] As such, when the organic light emitting layer EML and / or the thin film encapsulation layer TFEL are disposed between the first substrate 100 and the second substrate 300, the backlight unit BLU may be removed.

[0118] The bottom cover BC may be a container having an open top and a receiving space including a predetermined depth. For example, the bottom cover BC may include a bottom BC1 and a side wall BC2.

[0119] In some exemplary embodiments, the bottom BC1 may be flat and may be formed in a quadrilateral shape when viewed from the top. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, the bottom BC1 may have a curvature or may be formed in a circular shape or a polygonal shape other than a quadrilateral shape when viewed from the top.

[0120] In some exemplary embodiments, the side walls BC2 may extend from the edges of the bottom BC1 in the third direction DR3, respectively. In addition, a bottom cover hole BCH may be formed on one of the side walls BC2 where the flexible circuit board SFPC1 is positioned. The bottom cover hole BCH may provide a space to accommodate the flexible circuit board SFPC1 when the flexible circuit board SFPC1 is bent.

[0121] The middle frame MC may have an open top and an open bottom. For example, the middle frame MC may be implemented as a quadrilateral frame. However, it is to be understood that this is merely illustrative.

[0122] The middle frame MC may be disposed on the bottom cover BC and may expose the light source LS disposed on the bottom cover BC. The optical member LM is positioned on the middle frame MC and the light source LS may be spaced apart from the optical member LM by the middle frame MC. However, such a structure is merely illustrative and the present disclosure is not limited thereto.

[0123] The cover member TC may be arranged to surround the side surface of the display panel DPN. Figure 8 When the area of ​​the first substrate 100 is smaller than the area of ​​the second substrate 300 and the four side surfaces of the first substrate 100 are arranged to be more inward than the four side surfaces of the second substrate 300 as shown in , the cover member TC may surround the side surface of the first substrate 100. In some exemplary embodiments, the cover member TC may include a first cover member TC1, a second cover member TC2, a third cover member TC3, and a fourth cover member TC4. The first cover member TC1, the second cover member TC2, the third cover member TC3, and the fourth cover member TC4 may be adhered and fixed to the four side portions of the first substrate 100, respectively. However, it is to be understood that the present disclosure is not limited thereto. The cover member TC may be formed by five or more independent members, or the cover member TC may be formed as a single integral body.

[0124] The cover member TC may be fixedly coupled to the bottom cover BC. For example, in some exemplary embodiments, the side surface of the cover member TC may be fixed to the side wall BC2 of the bottom cover BC by screws, etc. In some exemplary embodiments, the side surface of the cover member TC may be fixed to the side wall BC2 of the bottom cover BC by an adhesive member, etc.

[0125] The cover member TC may be made of, but not limited to, SUS, PET, non-woven fabric, tape, or the like.

Figure 7 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line III-III'.

[0127] In the following description, it is described as follows Figure 8 As shown in , the area of ​​the first substrate 100 is smaller than the area of ​​the second substrate 300 and the four sides of the first substrate 100 are more inward than the four sides of the second substrate 300. In addition, the first cover member TC1 is arranged on the side surface of the display panel DPN on which the flexible circuit board SFPC1 is arranged, and the second cover member TC2 is opposite to the first cover member TC1 and the display panel DPN is located between the second cover member TC2 and the first cover member TC1.

For example, the first substrate 100 may be cut by a first distance d1. The first substrate 100 may be a TFT substrate, and the second substrate 300 may be a color filter substrate. As described above, the first distance d1 may be in the range of, but not limited to, 0.3 mm to 0.5 mm.

[0131] The first spacer CS1 and the second spacer CS2 may be arranged where the first substrate 100 and the second substrate 300 overlap each other in the third direction DR3. For example, the first spacer CS1 and the second spacer CS2 may be aligned with the end of the first substrate 100 in the third direction DR3. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, only one of the first spacer CS1 and the second spacer CS2 may be aligned with the end of the first substrate 100 in the third direction DR3.

[0132] The connection pads 130 may be arranged on the side surfaces of the first substrate 100, the interconnection 115, the first spacer CS1, and the second spacer CS2 and arranged under the second substrate 300. The upper end of the flexible circuit board SFPC1 connected to the connection pads 130 may be positioned on one side surface of the first substrate 100 and under the second substrate 300, and the lower ends of the driving circuit board SPCB and the flexible circuit board SFPC1 connected to the driving circuit board SPCB may be bent to be under the first substrate 100. As described above, the first substrate 100 is withdrawn from the second substrate 300 by the first distance d1 in the second direction DR2, and therefore, the connection pads 130 and the flexible circuit board SFPC1 connected to the connection pads 130 may be positioned under the second substrate 300.

[0133] The driving circuit board SPCB and the lower end of the flexible circuit board SFPC1 connected to the driving circuit board SPCB may be seated on the bottom BC1 of the bottom cover BC. In addition, the side wall BC2 of the bottom cover BC includes a bottom cover hole BCH, thereby providing a space that can accommodate the flexible circuit board SFPC1.

[0134] The first cover member TC1 may be disposed on the outer side of the flexible circuit board SFPC1 and under the second substrate 300. Specifically, the first cover member TC1 may be positioned on an opposite side of the flexible circuit board SFPC1 opposite to a side on which the first contact pads CP1 are disposed in the second direction DR2, and may overlap the second substrate 300 in the third direction DR3.

[0135] The first cover member TC1 and the flexible circuit board SFPC1 may be spaced apart from each other in the second direction DR2.

For example, the first cover member TC1 may be offset from the side surface of the second substrate 300 in the second direction DR2. In this way, when the first cover member TC1 is offset from the side surface of the second substrate 300 in the second direction DR2 as described above, there is the following advantage: when the spliced ​​display device TD is implemented, a space for connecting the cover member TC can be formed under the second substrate 300. Therefore, it is possible to prevent the bezel from increasing due to the space for connection. However, it is to be understood that the present disclosure is not limited thereto.

The second distance d2 may be equal to the first distance d1. For example, the second distance d2 may be in a range from, but not limited to, 0.3 mm to 0.5 mm. In some exemplary embodiments, because the flexible circuit board SFPC1 is not used, the second distance d2 may be less than the first distance d1.

For example, the first spacer CS1 and the second spacer CS2 may be aligned with the end of the first substrate 100 in the third direction DR3. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, only one of the first spacer CS1 and the second spacer CS2 may be aligned with the end of the first substrate 100 in the third direction DR3.

However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, the side wall BC2 may be bent at the end of the bottom BC1 in the third direction DR3 and extend to one side of the middle frame MC. In some exemplary embodiments, the side wall BC2 may be bent at the end of the bottom BC1 in the third direction DR3 to the lower surface of the second substrate 300.

In some exemplary embodiments, the lower end of the second cover member TC2 may be bent toward the bottom BC1 of the bottom cover BC and may be fixed to the side wall BC2 and the bottom BC1 of the bottom cover BC.

[0146] The first cover member TC1 and the second cover member TC2 may have the same shape. For example, the first cover member TC1 and the second cover member TC2 may have a strip shape extending in the third direction DR3, and may have the same length in the third direction DR3.

[0147] The second cover member TC2 may not be aligned with the side surface of the second substrate 300 in the third direction DR3. For example, the second cover member TC2 may be offset from the side surface of the second substrate 300 in the direction opposite to the second direction DR2. In this way, when the second cover member TC2 is offset from the side surface of the second substrate 300 in the direction opposite to the second direction DR2 as described above, there is the following advantage: when the spliced ​​display device TD is implemented, a space for connecting the cover member TC can be formed under the second substrate 300. Therefore, it is possible to prevent the bezel from increasing due to the space for connection. However, it is to be understood that the present disclosure is not limited thereto. The second cover member TC2 may be aligned with the side surface of the second substrate 300 in the third direction DR3.

The second side SF2 of the second substrate 300 may be aligned with the second side SF2 of the first substrate 100_4 in a third direction DR3. The third side SF3 of the second substrate 300 may protrude from the third side SF3 of the first substrate 100_4 by a third distance d3 in a direction opposite to the first direction DR1. The fourth side SF4 of the second substrate 300 may protrude from the fourth side SF4 of the first substrate 100_4 by a fourth distance d4 in the first direction DR1. The first distance d1 may be in a range of, but not limited to, from 0.3 mm to 0.5 mm.

[0182] The first cover member TC1 may overlap the second substrate 300 in the third direction DR3 and may not overlap the first substrate 100_4 in the third direction DR3 For example, the first cover member TC1 may be positioned below the second substrate 300 within a first distance d1.

[0183] The second cover member TC2 may not overlap the second substrate 300 and the first substrate 100_4 in the third direction DR3. For example, the second cover member TC2 may be coupled to the second side SF2 of each of the first substrate 100_4 and the second substrate 300.

[0185] The fourth cover member TC4 may overlap the second substrate 300 in the third direction DR3 and may not overlap the first substrate 100_4 in the third direction DR3. For example, the fourth cover member TC4 may be positioned below the second substrate 300 within a fourth distance d4.

[0186] Fig.13 is a cross-sectional view schematically showing a connection portion in which display devices of a spliced ​​display apparatus according to some exemplary embodiments of the present disclosure are connected to each other. The configurations of the respective display devices 1 of the spliced ​​display apparatus have been described above, and therefore, redundant description will be omitted.

[0187] refer to Fig.13 As described above, the side surface of the display panel DPN included in each display device 1 may have a step portion due to the area difference between the first substrate 100 and the second substrate 300. For example, the first substrate 100 has a smaller area than the second substrate 300, and therefore, the second substrate 300 protrudes from the first substrate 100. The connection pad 130 and the flexible circuit board SFPC1 connected to the connection pad 130 are arranged under the protruding portion of the second substrate 300. In addition, the first cover member TC1 and the second cover member TC2 may be arranged under the protruding portion of the second substrate 300.

[0188] The display panels DPN included in each display device 1 are stably fixed to the first and second cover members TC1 and TC2, and the respective display devices 1 can be connected to each other by the coupling member AML arranged between the first and second cover members TC1 and TC2, so that the reliability of the spliced ​​display device TD can be improved.

[0189] The first cover member TC1 and the second cover member TC2 are arranged further inward than the side surface of the second substrate 300, so that a space for accommodating the coupling member AML can be formed between the first cover member TC1 and the second cover member TC2, thereby reducing the size of the frame. Therefore, it is possible to suppress the grid pattern on the spliced ​​display device TD that may be perceived by the viewer, thereby improving the quality of the displayed image.

Fig.15 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig.16 is a cross-sectional view schematically showing a connection portion in which display devices of a spliced ​​display apparatus according to some exemplary embodiments of the present disclosure are connected to each other. Figures 14 to 16 An exemplary embodiment of Figure 6 , Figure 7 and Fig.13 The exemplary embodiment of FIG. 1 is different from that of FIG. 1 in that each of the cover members TC1_1 and TC2_1 includes a first portion P1 and a second portion P2. The description will focus on the difference, and redundant description will be omitted.

[0191] refer to Figures 14 to 16 , each of the first cover member TC1_1 and the second cover member TC2_1 may include a first portion P1 and a second portion P2.

[0192] The first portion P1 of the first cover member TC1_1 may extend in the third direction DR3, and the second portion P2 may extend from the upper end of the first portion P1 in a direction opposite to the second direction DR2. In addition, the first portion P1 of the second cover member TC2_1 may extend in the third direction DR3, and the second portion P2 may extend from the upper end of the first portion P1 in the second direction DR2.

[0193] The first portion P1 of each of the first cover member TC1_1 and the second cover member TC2_1 may be coupled and fixed to the sidewall BC2 of the bottom cover BC.

[0194] The second portion P2 of each of the first cover member TC1_1 and the second cover member TC2_1 may not be aligned with the side wall BC2 of the bottom cover BC in the third direction DR3, and may be coupled and fixed to the light blocking member SLM of the second substrate 300. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, the second portion P2 of each of the first cover member TC1_1 and the second cover member TC2_1 may be coupled and fixed to the second substrate 300. In some exemplary embodiments, the second portion P2 of each of the first cover member TC1_1 and the second cover member TC2_1 may be coupled and fixed to the light blocking member SLM and the second substrate 300.

[0195] As such, since each of the first cover member TC1_1 and the second cover member TC2_1 further includes the second portion P2 , the first cover member TC1_1 and the second cover member TC2_1 may be more stably coupled to the second substrate 300 .

[0196] In addition, for the spliced ​​display device TD_1 implemented by connecting the respective display devices 1_1 to each other using the coupling member AML_1, the second portion P2 of the first cover member TC1_1 and the second cover member TC2_1 of each display device 1_1 contacts each other to form a more robust structure, thereby improving the reliability of the spliced ​​display device TD_1.

[0197] Fig.17 It is along Figure 2A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line II-II'. Fig.18 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig.19 is a cross-sectional view schematically showing a connection portion in which display devices of a spliced ​​display apparatus according to some exemplary embodiments of the present disclosure are connected to each other. Figures 17 to 19 An exemplary embodiment of Figure 6 , Figure 7 and Fig.13 The exemplary embodiment of FIG. 1 is different in that each of the cover members TC1_2 and TC2_2 includes a first portion P1 and a second portion P2_1 . The description will focus on the difference, and redundant description will be omitted.

[0198] refer to Figures 17 to 19 , each of the first cover member TC1_2 and the second cover member TC2_2 may include a first portion P1 and a second portion P2_1.

[0199] The first portion P1 of the first cover member TC1_2 may extend in the third direction DR3, and the second portion P2_1 may extend from the upper end of the first portion P1 in the second direction DR2. In addition, the first portion P1 of the second cover member TC2_2 may extend in the third direction DR3, and the second portion P2_1 may extend from the upper end of the first portion P1 in a direction opposite to the second direction DR2.

[0200] The first portion P1 of each of the first cover member TC1_2 and the second cover member TC2_2 may be coupled and fixed to the sidewall BC2 of the bottom cover BC.

[0201] The second portion P2_1 of each of the first cover member TC1_2 and the second cover member TC2_2 may overlap with the side wall BC2 of the bottom cover BC, and may be coupled and fixed to the light blocking member SLM of the second substrate 300. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, the second portion P2_1 of each of the first cover member TC1_2 and the second cover member TC2_2 may be coupled and fixed to the second substrate 300. In some exemplary embodiments, the second portion P2_1 of each of the first cover member TC1_2 and the second cover member TC2_2 may be coupled and fixed to the light blocking member SLM and the second substrate 300.

[0202] The second portion P2_1 of the first cover member TC1_2 may be spaced apart from the flexible circuit board SFPC1 in the second direction DR2, but the present disclosure is not limited thereto. The second portion P2_1 of the first cover member TC1_2 may contact the flexible circuit board SFPC1 so that the flexible circuit board SFPC1 may be more reliably coupled to the side surface of the first substrate 100.

[0203] The second portion P2_1 of the second cover member TC2_2 may be spaced apart from the side surface of the second spacer CS2 in the second direction DR2. However, it is to be understood that the present disclosure is not limited thereto. The second portion P2_1 of the second cover member TC2_2 may contact the side surface of the second spacer CS2, or the second portion P2_1 of the second cover member TC2_2 may not contact the side surface of the second spacer CS2 and may extend further in a direction opposite to the second direction DR2.

[0204] As such, since each of the first cover member TC1_2 and the second cover member TC2_2 further includes the second portion P2_1 , the first cover member TC1_2 and the second cover member TC2_2 may be more stably coupled to the second substrate 300 .

[0205] In addition, compared to Figures 14 to 16 In the example shown in , the spliced ​​display device TD_2 is realized by connecting the various display devices 1_2 using the connecting member AML_2, which can further increase the adhesion area of ​​the connecting member AML_2, thereby improving the reliability of the spliced ​​display device TD_2.

[0206] Fig. 20 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line II-II'. Fig.21 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig. 22 is a cross-sectional view schematically showing a connection portion in which display devices of a spliced ​​display apparatus according to some exemplary embodiments of the present disclosure are connected to each other. Figure 20 to Figure 22 An exemplary embodiment of Figure 6 , Figure 7 and Fig.13 The exemplary embodiment of FIG. 1 is different in that a portion of each of the cover members TC1_3 and TC2_3 is inserted into the second substrate 300. The description will focus on the difference, and redundant description will be omitted.

[0207] refer to Figure 20 to Figure 22, the second substrate 300 may include a receiving groove AH. For example, the receiving groove AH may be formed in a portion of the second substrate 300 that does not overlap with the first substrate 100 in the third direction DR3. In addition, the light blocking member SLM may be positioned along or around the receiving groove AH.

[0208] The upper end of each of the first cover member TC1_3 and the second cover member TC2_3 may be inserted into the receiving groove AH of the second substrate 300. The receiving groove AH may have a shape conforming to the upper end of each of the first cover member TC1_3 and the second cover member TC2_3, and may be formed larger than the upper end of each of the first cover member TC1_3 and the second cover member TC2_3 so that the upper end may be inserted into the receiving groove AH.

[0209] The lower ends of the first cover member TC1_3 and the second cover member TC2_3 may be coupled and fixed to the side wall BC2 of the bottom cover BC, and the upper end of each of the first cover member TC1_3 and the second cover member TC2_3 may be coupled and fixed to the receiving groove AH of the second substrate 300. In some exemplary embodiments, an adhesive member may be arranged between the upper end of each of the first cover member TC1_3 and the second cover member TC2_3 and the receiving groove AH. In such a case, the adhesive member may include a light blocking material.

[0210] As such, since the upper end of each of the first cover member TC1_3 and the second cover member TC2_3 is inserted into the receiving groove AH of the second substrate 300 , the first cover member TC1_3 and the second cover member TC2_3 may be more stably coupled to the second substrate 300 .

[0211] In addition, compared to Figures 14 to 16 In the example shown in , the spliced ​​display device TD_3 is realized by connecting the various display devices 1_3 using the connecting member AML_3, which can further increase the adhesion area of ​​the connecting member AML_3, thereby improving the reliability of the spliced ​​display device TD_3.

[0212] Furthermore, since the second substrate 300 includes the receiving grooves AH, it is easier to align the cover members TC1_3 and TC2_3 with the second substrate 300 and to arrange the cover members TC1_3 and TC2_3 on the second substrate 300 .

[0213] Fig.23 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line II-II'. Fig.24 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig.25is a cross-sectional view schematically showing a connection portion in which display devices of a spliced ​​display apparatus according to some exemplary embodiments of the present disclosure are connected to each other. Figure 23 to Figure 25 An exemplary embodiment of Figure 6 , Figure 7 and Fig.13 The exemplary embodiment of FIG. 1 is different from that of FIG. 1 in that each of the cover members TC1_4 and TC2_4 includes a convex portion PP and a concave portion DP. The description will focus on the difference, and redundant description will be omitted.

[0214] refer to Figure 23 to Figure 25 , each of the first cover member TC1_4 and the second cover member TC2_4 may include a vertical portion VP, a convex portion PP, and a concave portion DP.

[0215] The vertical portions VP extending in the third direction DR3 may be respectively arranged at the upper and lower ends of each of the first and second cover members TC1_4 and TC2_4 coupled to the second substrate 300 and the sidewall BC2 of the bottom cover BC. In addition, the sidewalls BC2 of the bottom cover BC respectively coupled to the first and second cover members TC1_4 and TC2_4 may have the same length.

[0216] The protruding portion PP and the recessed portion DP of the first cover member TC1_4 and the second cover member TC2_4 are arranged between the vertical portion VP placed at the upper end and the vertical portion VP placed at the lower end. The protruding portion PP and the recessed portion DP may be alternately arranged in the third direction DR3. In this way, since each of the first cover member TC1_4 and the second cover member TC2_4 includes the protruding portion PP and the recessed portion DP, a buffering effect of the display device 1_4 can be achieved. Therefore, there is an advantage that damage or harm to the display device 1_4 caused by external force can be prevented.

[0217] In some exemplary embodiments, the convex portion PP of the first cover member TC1_4 may protrude in a direction opposite to the second direction DR2. The concave portion DP of the first cover member TC1_4 may protrude in the second direction DR2. The convex portion PP of the second cover member TC2_4 may protrude in the second direction DR2. The concave portion DP of the second cover member TC2_4 may protrude in a direction opposite to the second direction DR2.

[0218] In this way, the protruding portion PP of the first cover member TC1_4 can be matched with the recessed portion DP of the second cover member TC2_4, and the recessed portion DP of the first cover member TC1_4 can be matched with the protruding portion PP of the second cover member TC2_4. Therefore, when the spliced ​​display device TD_4 is realized by connecting the various display devices 1_4 using the connecting member AML_4, the protruding portion PP of the first cover member TC1_4 is inserted into the recessed portion DP of the second cover member TC2_4 and the connecting member AML_4 is located between them, while the protruding portion PP of the second cover member TC2_4 is inserted into the recessed portion DP of the first cover member TC1_4 and the connecting member AML_4 is located between them. Therefore, it is possible to increase the buffering effect on the spliced ​​display device TD_4 and realize a more robust structure.

[0219] Fig.26 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line II-II'. Fig. 27 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig.28 is a cross-sectional view schematically showing a connection portion in which display devices of a spliced ​​display apparatus according to some exemplary embodiments of the present disclosure are connected to each other. Figure 26 to Figure 28 An exemplary embodiment of Figure 23 to Figure 25 The exemplary embodiment of TC1_5 and TC2_5 is different in that the convex portion PP_1 and the concave portion DP_1 of each of the cover members TC1_5 and TC2_5 have different shapes. The description will focus on the difference, and redundant description will be omitted.

[0220] refer to Figure 26 to Figure 28 , each of the first cover member TC1_5 and the second cover member TC2_5 may include a vertical portion VP, a convex portion PP_1, and a concave portion DP_1.

[0221] The protrusion PP_1 and the recess DP_1 of the first cover member TC1_5 and the second cover member TC2_5 may be arranged in a sawtooth shape in which ridges and valleys are alternately arranged. Since each of the first cover member TC1_5 and the second cover member TC2_5 includes the protrusion PP_1 and the recess DP_1 in a sawtooth shape, the buffering effect on the display device 1_5 can be improved. Therefore, there is an advantage that damage or harm to the display device 1_5 caused by external force can be prevented.

[0222] In some exemplary embodiments, the protruding portion PP_1 of the first cover member TC1_5 may be a ridge protruding in a direction opposite to the second direction DR2. The recessed portion DP_1 of the first cover member TC1_5 may be a valley protruding in the second direction DR2. The protruding portion PP_1 of the second cover member TC2_5 may be a ridge protruding in the second direction DR2. The recessed portion DP_1 of the second cover member TC2_5 may be a valley protruding in a direction opposite to the second direction DR2.

[0223] In this way, the protruding portion PP_1 of the first cover member TC1_5 can match the recessed portion DP_1 of the second cover member TC2_5, and the recessed portion DP_1 of the first cover member TC1_5 can match the protruding portion PP_1 of the second cover member TC2_5. Therefore, when the spliced ​​display device TD_5 is realized by connecting the various display devices 1_5 using the connecting member AML_5, the protruding portion PP_1 of the first cover member TC1_5 is inserted into the recessed portion DP_1 of the second cover member TC2_5 and the connecting member AML_5 is located between them, while the protruding portion PP_1 of the second cover member TC2_5 is inserted into the recessed portion DP_1 of the first cover member TC1_5 and the connecting member AML_5 is located between them. Therefore, it is possible to increase the buffering effect on the spliced ​​display device TD_5 and realize a more robust structure.

[0224] In addition, compared to Figure 23 to Figure 25 In the example shown in FIG. 1 , since the convex portion PP_1 and the concave portion DP_1 of each of the first cover member TC1_5 and the second cover member TC2_5 have a sawtooth shape, the convex portion PP_1 and the concave portion DP_1 may be more easily coupled to each other.

[0225] Fig.29 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line II-II'. Fig.30 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig.29 and Fig.30 The implementation method and Figure 6 and Figure 7 The exemplary embodiment of FIG. 1 is different in that a first substrate 100 as a TFT substrate is disposed on a second substrate 300 as a color filter substrate. The description will focus on the difference, and redundant description will be omitted.

[0226] refer to Fig.29In the display device 1_6 according to some exemplary embodiments, the first substrate 100 may be arranged on the second substrate 300. The first substrate 100 may be a TFT substrate, and the second substrate 300 may be a color filter substrate. The second substrate 300 may be arranged below the first substrate 100 and may be withdrawn from the first substrate 100 by a first distance d1 in the second direction DR2. For example, the second substrate 300 may be cut by a first distance d1. As described above, the first distance d1 may be in a range of, but not limited to, 0.3 mm to 0.5 mm. The element may not be arranged on a portion of the first substrate 100 protruding from the second substrate 300. Only the light blocking member SLM may be arranged on the protruding portion of the first substrate 100.

[0227] The interconnection 115 may be positioned on the second substrate 300. A flexible circuit board SFPC1 connected to one side of the second substrate 300 through an outer wire bonding (OLB) technique may be disposed.

[0228] The liquid crystal layer 200 and the spacer CS may be arranged between the first substrate 100 and the second substrate 300. The spacer CS may include a first spacer CS1 and a second spacer CS2. For example, the first spacer CS1 and the second spacer CS2 may be aligned with the end of the second substrate 300 in the third direction DR3. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, only one of the first spacer CS1 and the second spacer CS2 may be aligned with the end of the second substrate 300 in the third direction DR3.

[0229] The first spacer CS1 may be positioned between the first substrate 100 and the second substrate 300, and the second spacer CS2 may be positioned between the first spacer CS1 and the second substrate 300. The first spacer CS1 may include a blue colorant.

[0230] The connection pads 130 may be arranged on the side surfaces of the second substrate 300, the interconnection 115, the first spacer CS1, and the second spacer CS2 and arranged under the first substrate 100. In addition, the upper end of the flexible circuit board SFPC1 connected to the connection pads 130 may be positioned on one side surface of the second substrate 300 and under the first substrate 100, and the lower ends of the driving circuit board SPCB and the flexible circuit board SFPC1 connected to the driving circuit board SPCB may be bent under the second substrate 300. In this way, the second substrate 300 is withdrawn from the first substrate 100 by the first distance d1 in the second direction DR2, and therefore, the connection pads 130 and the flexible circuit board SFPC1 connected to the connection pads 130 may be positioned under the first substrate 100.

[0231] The first cover member TC1 may be disposed on the outer side of the flexible circuit board SFPC1 and under the first substrate 100. Specifically, the first cover member TC1 may be positioned on an opposite side of the flexible circuit board SFPC1 opposite to a side on which the first contact pads CP1 are disposed in the second direction DR2, and may overlap the first substrate 100 in the third direction DR3.

[0232] The light blocking member SLM for preventing light leakage may be arranged on the corners and side surfaces of the first substrate 100. The upper end of the first cover member TC1 may be adhered and fixed to the light blocking member SLM by an adhesive member. However, it is to be understood that the present disclosure is not limited thereto. The upper end of the first cover member TC1 may be adhered and fixed to the first substrate 100 by an adhesive member.

[0233] The first cover member TC1 may not be aligned with one side surface of the first substrate 100 in the third direction DR3. For example, the first cover member TC1 may be offset from the side surface of the first substrate 100 in the second direction DR2. In this way, when the first cover member TC1 is offset from the side surface of the first substrate 100 in the second direction DR2 as described above, there is the following advantage: when the spliced ​​display device TD is implemented, a space for connecting the cover member TC can be formed under the first substrate 100. Therefore, it is possible to prevent the bezel from increasing due to the space for connection. However, it is to be understood that the present disclosure is not limited thereto. The first cover member TC1 may be aligned with the side surface of the first substrate 100 in the third direction DR3.

[0234] refer to Fig.30 , the second substrate 300 may be withdrawn from the first substrate 100 by a second distance d2 in a direction opposite to the second direction DR2. For example, the second substrate 300 may be cut by a second distance d2. The first substrate 100 may be a TFT substrate, and the second substrate 300 may be a color filter substrate. The second distance d2 may be equal to the first distance d1. For example, the second distance d2 may be in a range from, but not limited to, 0.3 mm to 0.5 mm. In some exemplary embodiments, since the flexible circuit board SFPC1 does not exist, the second distance d2 may be less than the first distance d1.

[0235] The liquid crystal layer 200 , a first spacer CS1 surrounding the liquid crystal layer 200 , and a second spacer CS2 may be disposed between the second substrate 300 and the first substrate 100 .

[0236] The second cover member TC2 may be spaced apart from the side surface of the second substrate 300 in the second direction DR2 and may be positioned under the first substrate 100. Specifically, an upper end of the second cover member TC2 may be adhered and fixed to the light blocking member SLM by an adhesive member, and a side surface of the second cover member TC2 may be coupled to the sidewall BC2 of the bottom cover BC.

[0237] The second cover member TC2 may not be aligned with one side surface of the first substrate 100 in the third direction DR3. For example, the second cover member TC2 may be offset from the side surface of the first substrate 100 in a direction opposite to the second direction DR2. In this way, when the second cover member TC2 is offset from the side surface of the first substrate 100 in a direction opposite to the second direction DR2 as described above, there is the following advantage: when the spliced ​​display device TD is implemented, a space for connecting the cover member TC can be formed under the first substrate 100. Therefore, it is possible to prevent the bezel from increasing due to the space for connection. However, it is to be understood that the present disclosure is not limited thereto. The second cover member TC2 may be aligned with one side surface of the first substrate 100 in the third direction DR3.

[0238] Fig.31 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments of the present disclosure taken along line II-II'. Fig.32 It is along Figure 2 A cross-sectional view of a display device according to some exemplary embodiments taken along line III-III'. Fig.31 and Fig.32 An exemplary embodiment of Fig.29 and Fig.30 The exemplary embodiment of FIG. 1 is different from that of FIG. 1 in that at least one of the elements arranged on the first substrate 100 extends beyond the second substrate 300. The description will focus on the difference, and redundant description will be omitted.

[0239] refer to Fig.31 and Fig.32In the display device 1_7 according to some exemplary embodiments, the first substrate 100 may be arranged on the second substrate 300. The first substrate 100 may be a TFT substrate, and the second substrate 300 may be a color filter substrate. The second substrate 300 may be arranged below the first substrate 100 and may be withdrawn from the first substrate 100 by a first distance d1 in the second direction DR2. At least one of the elements arranged on the first substrate 100 may extend on a portion of the first substrate 100 protruding from the second substrate 300 and be arranged on a portion of the first substrate 100 protruding from the second substrate 300. For example, the first spacer CS1_1 of the spacer CS_2 may extend to a region where the first substrate 100 and the second substrate 300 do not overlap with each other. When the first spacer CS1_1 extends to the end of the first substrate 100, the upper ends of the first cover member TC1_6 and the second cover member TC2_6 may be coupled to the first spacer CS1_1. In such a case, the light blocking member SLM may be arranged only on a portion of the upper surface and the side surface of the first substrate 100, and the length of the first spacer CS1_1 may be different from the length of the second spacer CS2. However, it is to be understood that the present disclosure is not limited thereto. In some exemplary embodiments, at least one of the elements arranged on the first substrate 100 may extend to a region where the first substrate 100 and the second substrate 300 do not overlap each other, but may not reach the end of the first substrate 100. In such a case, the upper ends of the first cover member TC1_6 and the second cover member TC2_6 may be coupled and fixed to the first substrate 100 by an adhesive member.

[0240] In summarizing the detailed description, it will be appreciated by those skilled in the art that many variations and modifications may be made to the exemplary embodiments without substantially departing from the principles of the present invention. Therefore, the disclosed exemplary embodiments of the present invention are used only in a general and descriptive sense and not for limiting purposes.
