[0043] FIG. 1 is a perspective view illustrating a display device according to one embodiment of the present disclosure. FIG. 2 is an exploded view illustrating a display device according to one embodiment of the present disclosure.

[0044] Referring to FIGS. 1 and 2, a display device (1) according to one embodiment of the present disclosure is a device that processes an image signal received from the outside and can visually display the processed image. The display device (1) can be implemented in various forms, such as a television (TV), a monitor (a type of computer output device), a portable multimedia device, a portable communication device, etc. As long as the display device (1) is a device that visually displays an image, its form is not limited to that shown in FIGS. 1 and 2.

[0045] In addition, the display device (1) may be a large format display (LFD) installed outdoors, such as on a building rooftop or a bus stop. Here, the outdoors is not necessarily limited to outdoors, and the display device (1) may be installed in any indoor location where a large number of people may come and go, such as a subway station, shopping mall, movie theater, company, or store.

[0046] The display device (1) can be installed in a standing manner on an indoor or outdoor floor or furniture, or can be installed in a wall-mounted manner on a wall or inside a wall.

[0047] In FIGS. 1 and 2, the display device (1) is described as a flat display device with a flat screen as an example, but is not limited thereto, and the display device according to the concept of the present disclosure can also be applied to a curved display device or a bendable or flexible display device in which the flat state and the curved state can be changed. In addition, the configuration of the present disclosure can be applied to display devices of various shapes regardless of the screen size or ratio of the display device.

[0048] The display device (1) can receive content including video signals and audio signals from various content sources, and output video and audio corresponding to the video signals and audio signals. For example, the display device (1) can receive content data via a broadcast reception antenna or a wired cable, receive content data from a content playback device, or receive content data from a content provider's content provision server.

[0049] The display device (1) can display an image corresponding to video data and output a sound corresponding to audio data. For example, the display device (1) can restore a plurality of image frames included in the video data and continuously display the plurality of image frames. In addition, the display device (1) can restore an audio signal included in the audio data and continuously output a sound according to the audio signal.

[0050] The display device (1) may include a display panel (20). The display panel (20) may be configured to display an image. The display panel (20) forms the front surface of the display device (1) and may display an image in the front. For example, the display panel (20) may display a still image or a moving image. For example, the display panel (20) may display a two-dimensional flat image or a three-dimensional stereoscopic image utilizing the parallax of the user's two eyes.

[0051] A display panel (20) may be provided with a plurality of pixels. An image displayed on the display panel (20) may be formed by light emitted from each of the plurality of pixels. For example, an image may be formed on the screen by combining the light emitted from the plurality of pixels like a mosaic.

[0052] Each of the plurality of pixels provided on the display panel (20) can emit light of various brightness and various colors. Specifically, each of the plurality of pixels can include sub-pixels, and the sub-pixels can include a red sub-pixel capable of emitting red light, a green sub-pixel capable of emitting green light, and a blue sub-pixel capable of emitting blue light. For example, red light can represent light with a wavelength of approximately 620 nm (nanometer, one billionth of a meter) to 750 nm, green light can represent light with a wavelength of approximately 495 nm to 570 nm, and blue light can represent light with a wavelength of approximately 450 nm to 495 nm. Each of the plurality of pixels can emit light of various brightness and various colors by a combination of light emitted from the red sub-pixel, the green sub-pixel, and the blue sub-pixel, respectively.

[0053] For example, the display panel (20) may be configured as a panel of a light-emitting display type, such as a liquid crystal display (LCD). Alternatively, the display panel (20) may be configured as a panel of a self-luminous display type, such as an organic light-emitting diode (OLED) or a micro-LED.

[0054] On one side of the display panel (20), a cable (20a) for transmitting image data to the display panel (20) and a display driver integrated circuit (DDI) (30) (hereinafter referred to as a 'driver IC') for processing digital image data and outputting an analog image signal may be provided.

[0055] The cable (20a) can electrically connect between a source board (70) to be described later and a driver IC (30). In addition, the cable (20a) can electrically connect between a driver IC (30) and a display panel (20). The cable (20a) may include a flexible flat cable or a film cable that can be bent.

[0056] The driver IC (30) can receive image data and power from the source board (70) through the cable (20a), and transmit image data and driving current to the display panel (20) through the cable (20a).

[0057] The cable (20a) and the driver IC (30) can be implemented as a single unit, such as a film cable, a chip on film (COF), a tape carrier packet (TCP), etc. In other words, the driver IC (30) can be placed on the cable (20b). However, this is not limited thereto, and the driver IC (30) can be placed on the display panel (20).

[0058] For example, the cable (20a) and driver IC (30) may be placed on the lower side of the display panel (20). The cable (20a) may be connected to the lower part of the display panel (20).

[0059] When the display device (1) includes a display panel (20) of a light-emitting type, the display device (1) may include a backlight unit (40) arranged to irradiate light toward the display panel (20). The backlight unit (40) may be arranged to be positioned at the rear of the display panel (20) and to irradiate light toward the front where the display panel (20) is located. Specifically, the backlight unit (40) may be configured as a surface light source. The display panel (20) may block or allow light emitted from the backlight unit (40) to pass through.

[0060] The backlight unit (40) may include a point light source that emits monochromatic light or white light, and may be configured to refract, reflect, and scatter light to convert light emitted from the point light source into uniform surface light. The backlight unit (40) may emit uniform surface light toward the front by refracting, reflecting, and scattering light emitted from the point light source.

[0061] For example, the backlight unit (40) may include a light source module including a plurality of light sources arranged to irradiate light and a light source substrate on which the plurality of light sources are mounted. In addition, the backlight unit (40) may include a reflective sheet arranged to reflect light emitted from the light source module forward. In addition, the backlight unit (40) may include a diffusion plate arranged to uniformly diffuse light emitted from the light source module, and an optical sheet (diffusion sheet, prism sheet, reflective polarizing sheet, quantum dot sheet, etc.) arranged to refract and scatter light to improve the brightness and uniformity of the light.

[0062] The display device (1) may include various circuit boards (50, 60, 70 (see FIG. 3)). Electronic components may be mounted on the circuit boards (50, 60, 70), and circuits including the electronic components may be provided. For example, the circuits of the circuit boards (50, 60, 70) may be formed by printing a conductive material such as copper (Cu) in a circuit line pattern on an electrically insulating substrate. The circuit boards (50, 60, 70) may be provided to control various components for performing the functions of the display device (1), such as the display panel (20), the light source module of the backlight unit (40), and to supply power to the components.

[0063] For example, the display device (1) may include various circuit boards such as a main board (50), a power supply board (60), and a source board (70, see FIG. 3).

[0064] The main board (50) can control the overall operation of the display device (1). The main board (50) can include a processor and a power management device for driving the display device (1). The main board (50) can include a control circuit for controlling components such as a display panel (20), a light source module of a backlight unit (40), a communication module of the display device (1), and a content receiving unit for receiving content data from content sources. Electronic components constituting the control circuit of the main board (50) can be mounted on one side of the main board (50) facing in the opposite direction (i.e., rearward) from the bottom chassis (13).

[0065] The power supply board (60) may be provided to supply power to various components of the display device (1). The power supply board (60) may include a Switched Mode Power Supply (SMPS) board. The power supply board (60) may include a power supply circuit for supplying power to components such as the display panel (20) and the light source module of the backlight unit (40). Electronic components constituting the control circuit of the power supply board (60) may be mounted on one side of the power supply board (60) facing in the opposite direction (i.e., rearward) from the bottom chassis (13).

[0066] The source board (70) can control the display panel (20). The source board (70) can control the display panel (20) by transmitting a driving signal to the display panel (20) through a cable (20a). The source board (70) can control the display panel (20) by controlling the driver IC (30) to transmit a driving signal to the display panel (20). The source board (70) can include a control circuit for controlling the display panel (20). Electronic components constituting the control circuit of the source board (70) can be mounted on one side of the source board (70) facing the opposite direction (i.e., rear) from the bottom chassis (13) (the first side (71) of the source board (70), see FIGS. 14 to 17, etc.).

[0067] Circuit boards such as the main board (50), the power supply board (60), and the source board (70) may be arranged independently of each other or may be arranged in a combined manner. When the circuit boards are arranged independently of each other, the circuit boards may be electrically connected to each other to transmit and receive data, signals, or power. That is, the main board (50), the power supply board (60), and the source board (70) may be electrically connected to each other. For example, the main board (50), the power supply board (60), and the source board (70) may be electrically connected to each other by cables to perform a function for driving the display device (1). The cables may include various types of cables such as a film cable, an FFC (Flexible Flat Cable), and an FPCB (Flexible Printed Circuit Board).

[0068] The main board (50), power supply board (60), and source board (70) can each be supported by a display case (10) described later. Specifically, the main board (50), power supply board (60), and source board (70) can each be mounted on a bottom chassis (13) described later.

[0069] The display device (1) may include a display case (10) that supports various components of the display device (1). The various components of the display device (1) may be accommodated inside the display case (10). The display case (10) may form the exterior of the display device (1).

[0070] For example, the display case (10) can support a display panel (20). For example, the display case (10) can support a backlight unit (40). For example, the display case (10) can support a circuit board (50, 60, 70).

[0071] The display case (10) may include a top chassis (11). The top chassis (13) may include a top chassis (11) that supports the front or side of the display panel (20). For example, the top chassis (11) may be provided in a shape of an approximately square frame. The "front side of the display panel (20)" mentioned here means one side of the display panel (20) facing forward where the display panel (20) displays an image. In addition, the "side side of the display panel (20)" mentioned here means the frame surface of the display panel (20).

[0072] The top chassis (11) may form a bezel that is positioned to face the front of the display device (1) and support the front of the display panel (20). However, if the display device (1) is a bezel-less type display device with a very narrow or no bezel, the top chassis (11) may be provided to support only the side of the display panel (20). Alternatively, if the bottom chassis (13) supports the side of the display panel (20), the display case (10) may not include the top chassis (11).

[0073] The display case (10) may include a front cover (12) that covers the cable (20a). Specifically, a bezel-less type display device (1) may include a front cover (12) to prevent the cable (20a) from being exposed to the outside.

[0074] The front cover (12) can be coupled to the top chassis (11). For example, the front cover (12) can be coupled to the lower part of the top chassis (11) to cover the cable (20a).

[0075] The front cover (12) may have the shape of a bar extending in approximately one direction. For example, the front cover (12) may have the shape of a bar extending in the left-right direction (Y).

[0076] However, in contrast, the display case (10) may not include a front cover (12) configured separately from the top chassis (11), in which case the cable (20a) may be covered by the top chassis (11).

[0077] The display case (10) may include a bottom chassis (13). The bottom chassis (13) may cover the rear of the display panel (20). The bottom chassis (13) may be coupled to the rear of the top chassis (11). The bottom chassis (13) may support various components of the display device (1), such as a backlight unit (40), a main board (50), a power supply board (60), and a source board (70).

[0078] The backlight unit (40) can be placed at the front of the bottom chassis (13). The backlight unit (40) can be mounted on the front of the bottom chassis (13). The "front of the bottom chassis (13)" as used herein means one side of the bottom chassis (13) facing forward toward the display panel (20).

[0079] The main board (50), the power supply board (60), and the source board (70) may each be placed at the rear of the bottom chassis (13). The main board (50), the power supply board (60), and the source board (70) may each be mounted at the rear of the bottom chassis (13). The "rear of the bottom chassis (13)" herein refers to one side of the bottom chassis (13) facing the rear, opposite the display panel (20).

[0080] The bottom chassis (13) may be formed to have a roughly flat plate shape, but is not limited thereto.

[0081] The bottom chassis (13) may be configured to include a material with high thermal conductivity to dissipate heat generated from the backlight unit (40) to the outside. For example, the bottom chassis (13) may be configured to include a metal material such as aluminum or SUS, or a plastic material such as ABS.

[0082] The display case (10) may include a rear cover (14). The rear cover (14) may be positioned at the rear of the bottom chassis (13).

The rear cover (14) may cover various components (e.g., a main board (50), a power supply board (60), a source board (70), etc.) mounted at the rear of the bottom chassis (13).

[0083] The configuration of the display device (1) described above with reference to FIGS. 1 and 2 is merely an example of the present disclosure, and the spirit of the present disclosure is not limited thereto. The display device (1) may include various configurations for performing the function of providing an image.

[0084] For example, unlike as shown in FIGS. 1 and 2, the display device (1) may include a self-luminous display panel and may not include a backlight unit that irradiates light toward the display panel.

[0085] FIG. 3 is a rear view of a bottom chassis and a source board, and other components of a display device according to one embodiment of the present disclosure. FIG. 4 is an enlarged view of A in FIG. 3. FIG. 5 is an exploded view of the bottom chassis, board holder, and source board illustrated in FIG. 4.

[0086] Referring to FIGS. 3 to 5, in a display device (1) according to one embodiment of the present disclosure, a circuit board (50, 60, 70) may be supported by a bottom chassis (13). The circuit board (50, 60, 70) may be mounted on the bottom chassis (13). The circuit board (50, 60, 70) may be mounted on the rear surface of the bottom chassis (13).

[0087] For example, the main board (50) may be mounted in an area inside the edge portion (13a) of the rear of the bottom chassis (13). As illustrated in FIG. 3, the main board (50) may be placed in an area that is biased to one side from the center portion of the bottom chassis (13). Alternatively, the main board (50) may be placed in an area adjacent to the center portion of the bottom chassis (13).

[0088] The main board (50) can be fixed to the bottom chassis (13) by various fixing structures such as a fixing clip, a hook structure, or a screw.

[0089] For example, the power supply board (60) may be mounted in an area inside the edge portion (13a) of the rear of the bottom chassis (13). As illustrated in FIG. 3, the power supply board (60) may be placed in an area that is biased to one side from the center of the bottom chassis (13). At this time, as illustrated in FIG. 3, the main board (50) and the power supply board (60) may be placed to be biased to opposite sides from the center of the bottom chassis (13).

[0090] In Fig. 3, the main board (50) is shown to be positioned on the left and the power supply board (60) is positioned on the right, but the positions of the main board (50) and the power supply board (60) are not limited thereto. Alternatively, the main board (50) and the power supply board (60) may be positioned to be biased in the same direction from the center of the bottom chassis (13).

[0091] Alternatively, the power supply board (60) may be placed in an area adjacent to the center of the bottom chassis (13).

[0092] The power supply board (60) can be fixed to the bottom chassis (13) by various fixing structures such as a fixing clip, a hook structure, or a screw.

[0093] For example, the source board (70) may be mounted on the edge portion (13a) of the rear side of the bottom chassis (13). The edge portion (13a) may include a region extending inward from the outline of the bottom chassis (13) in a range adjacent to the outline. That is, the source board (70) may be positioned adjacent to the edge portion of the rear side of the bottom chassis (13). By mounting the source board (70) on the edge portion (13a) of the bottom chassis (13), the distance between the source board (70) and the edge of the display panel (20) may be reduced, and the length of the cable (20a) connecting the source board (70) and the edge of the display panel (20) may be shortened.

[0094] More specifically, as illustrated in FIG. 3, the source board (70) may be positioned adjacent to the lower edge of the bottom chassis (13). The source board (70) may be positioned along the lower edge of the bottom chassis (13). The source board (70) may extend along the lower edge of the bottom chassis (13).

[0095] However, in contrast to this, the source board (70) may be placed at various locations on the edge portion (13a) of the rear of the bottom chassis (13). The source board (70) may be placed along the long edge of the edge of the bottom chassis (13) or along the short edge. The source board (70) may also be placed along the upper edge of the bottom chassis (13). The source board (70) may also be placed along the left edge or the right edge of the bottom chassis (13).

[0096] For example, the source board (70) may be provided in 2 to 3 or more pieces. The plurality of source boards (70) may be electrically connected to each other. The plurality of source boards (70) may be arranged side by side at the edge portion (13a) of the bottom chassis (13). For example, as illustrated in FIG. 3, the plurality of source boards (70) may be arranged side by side along the lower edge of the bottom chassis (13). However, the number of source boards (70) may vary depending on the size of the display panel (20), and the display device (1) may include only one integrated source board (70).

[0097] As illustrated in FIGS. 3 to 5, the edge portion (13a) on the rear side of the bottom chassis (13) may extend in an inclined direction with respect to the extension direction of the display panel (20). For example, the edge portion (13a) may be formed to be inclined so as to extend forward as it faces the edge direction. Alternatively, the edge portion (13a) may be arranged parallel to the display panel (20).

[0098] The display device (1) may include a board holder (100) that secures a source board (70) to a bottom chassis (13). The board holder (100) may mount the source board (70) to the bottom chassis (13). The source board (70) may be mounted to the board holder (100) and supported by the bottom chassis (13). The source board (70) may be mounted to the board holder (100) and secured to the bottom chassis (13).

[0099] The board holder (100) can be placed on the rear of the bottom chassis (13). The board holder (100) can be placed on the rear of the bottom chassis (13) to mount the source board (70) on the rear of the bottom chassis (13). Specifically, the board holder (100) can be placed on the edge portion (13a) of the rear of the bottom chassis (13). For example, the board holder (100) can be placed adjacent to the lower edge of the bottom chassis (13).

[0100] The board holder (100) can be fixed to the bottom chassis (13). The board holder (100) can be coupled to the bottom chassis (13). The board holder (100) can be coupled to the rear of the bottom chassis (13). The board holder (100) can be coupled to the edge portion (13a) of the rear of the bottom chassis (13). The position at which the board holder (100) is coupled to the bottom chassis (13) can vary depending on the design position of the source board (70).

[0101] For example, the bottom chassis (13) may include a joining hole (13b) formed to allow the board holder (100) to be joined, and the bottom chassis (13) may include a chassis joining portion (111, 112, see FIG. 8) formed to be joined to the bottom chassis (13) by penetrating the joining hole (13b). As an example, the joining hole (13b) may be provided in the edge portion (13a) of the bottom chassis (13).

[0102] In contrast, the board holder (100) may be fixed to the bottom chassis (13) by various structures, such as being fastened to the bottom chassis (13) by a screw. Alternatively, the board holder (100) may be formed integrally with the bottom chassis (13). Hereinafter, an embodiment in which the board holder (100) is formed as a separate part from the bottom chassis (13) and has a structure that is coupled to the coupling hole (13b) of the bottom chassis (13) will be described, and a detailed description of the structure that allows the board holder (100) to be coupled to the coupling hole (13b) will be described later.

[0103] The display device (1) may include a plurality of board holders (100). The plurality of board holders (100) may each secure a plurality of source boards (70) to the bottom chassis (13). Alternatively, the plurality of board holders (100) may secure only one source board (70) to the bottom chassis (13). The number of board holders (100) may vary depending on the size of the display panel (20), the length and number of source boards (70), etc.

[0104] FIG. 6 is a perspective view illustrating a board holder included in a display device according to an embodiment of the present disclosure when viewed from one direction. FIG. 7 is a perspective view illustrating a board holder included in a display device according to an embodiment of the present disclosure when viewed from another direction. FIG. 8 is a perspective view illustrating a board holder included in a display device according to an embodiment of the present disclosure when viewed from another direction. FIG. 9 is a view illustrating a state before a source board is mounted on a board holder included in a display device according to an embodiment of the present disclosure. FIG. 10 is a view illustrating a state in which a source board of a first thickness is mounted on a board holder included in a display device according to an embodiment of the present disclosure. FIG. 11 is a view illustrating a state in which a source board of a second thickness is mounted on a board holder included in a display device according to an embodiment of the present disclosure.

[0105] Referring to FIGS. 6 to 11, a board holder (100) of a display device (1) according to one embodiment of the present disclosure may include a holder body (110). The holder body (110) may be fixed to a bottom chassis (13). The holder body (110) may be mounted to the bottom chassis (13). The holder body (110) may be supported by the bottom chassis (13).

[0106] The holder body (110) can be in contact with the rear surface of the bottom chassis (13). The holder body (110) can be in contact with the edge portion (13a) of the bottom chassis (13). One side of the holder body (110) opposite the source board (70) can be in contact with the rear surface of the bottom chassis (13).

[0107] When the source board (70) is mounted on the board holder (100), the source board (70) can be positioned on the opposite side of the bottom chassis (13) with respect to the holder body (110).

[0108] The holder body (110) can be coupled to the rear of the bottom chassis (13). Specifically, the holder body (110) can be coupled to the edge portion (13a) of the rear of the bottom chassis (13). The holder body (110) can be coupled to the rear of the bottom chassis (13) and fixed to the bottom chassis (13). The holder body (110) can be coupled to the rear of the bottom chassis (13) and supported by the bottom chassis (13). Since the holder body (110) is supported by the bottom chassis (13), the source board (70) mounted on the board holder (100) can also be supported by the bottom chassis (13).

[0109] The holder body (110) can be coupled to a coupling hole (13b) formed by penetrating the edge portion (13a) of the bottom chassis (13). The holder body (110) can include a chassis coupling portion (111, 112) that is arranged to be coupled to the coupling hole (13b).

[0110] For example, the holder body (110) may include a first chassis coupling portion (111) that is hooked and coupled to a coupling hole (13b). The first chassis coupling portion (111) has a shape that penetrates the coupling hole (13b) and extends from the front of the coupling hole (13b) to the outer edge of the coupling hole (13b), so that it can be hooked and coupled to the coupling hole (13b). That is, the first chassis coupling portion (111) can be hooked and coupled to the coupling hole (13b) by contacting the front surface of the bottom chassis (13). By the first chassis coupling portion (111), the board holder (100) can be restrained from moving in a direction orthogonal to the edge portion (13a). Here, the "direction orthogonal to the edge portion (13a)" means a direction that is approximately parallel to the normal direction of the edge portion (13a), or a direction that is approximately parallel to the direction in which the coupling hole (13b) is penetrated.

[0111] In addition, the holder body (110) may include a second chassis coupling portion (112). The second chassis coupling portion (112) may pass through the coupling hole (13b). When the board holder (100) is coupled to the bottom chassis (13), the first chassis coupling portion (111) may be positioned on one side of the edge of the coupling hole (13b), and the second chassis coupling portion (112) may be positioned on the other side of the edge of the coupling hole (13b). Therefore, the board holder (100) may be restrained from moving in a direction parallel to the edge portion (13a) by the first chassis coupling portion (111) and the second chassis coupling portion (112). Here, the “direction parallel to the edge portion (13a)” means any straight line direction on a plane parallel to the edge portion (13a), or a direction approximately orthogonal to the normal direction of the edge portion (13a).

[0112] For example, a part of the first chassis coupling portion (111) has a structure that extends away from the second chassis coupling portion (112) in front of the coupling hole (13b) and can be hooked to the coupling hole (13b).

[0113] For example, the second chassis joint (112) may extend in a direction approximately perpendicular to the edge portion (13a).

[0114] For example, the second chassis coupling portion (112) may be positioned spaced apart from the first chassis coupling portion (111).

[0115] The board holder (100) may include a catch (120) provided to support the source board (70). Specifically, the catch (120) may support one side of the source board (70) opposite the bottom chassis (13). The catch (120) may be provided to contact one side of the source board (70) opposite the bottom chassis (13) to support one side of the source board (70). The catch (120) may be provided to catch one side of the source board (70) opposite the bottom chassis (13), thereby preventing the source board (70) from being separated from the board holder (100). Hereinafter, the side of the source board (70) opposite the bottom chassis (13) is referred to as the first side (71) of the source board (70). The catch (120) is positioned on the side opposite to the bottom chassis (13) with respect to the holder body (110) and can support the first side (71) of the source board (70). The first side (71) of the source board (70) can be defined as one side of the source board (70) opposite to the holder body (110).

[0116] The hook (120) may be referred to by a term such as “hook (120)”.

[0117] The catch (120) may be connected to the holder body (110). Specifically, the board holder (100) may include a connecting portion (130) connecting the holder body (110) and the catch (120). The connecting portion (130) may extend from the holder body (110) in a direction away from the bottom chassis (13). The catch (120) may protrude from the connecting portion (130).

[0118] The source board (70) mounted on the board holder (100) can be positioned inwardly with respect to the connection portion (130). The “inward direction” or “outward direction” can be defined based on the board holder (100), and the position where the source board (70) mounted on the board holder (100) is positioned can be defined as the inside of the board holder (100). Since the source board (70) is positioned inwardly with respect to the connection portion (130), the catch portion (120) can protrude inwardly from the connection portion (130) to support the first surface (71) of the source board (70).

[0119] The catch (120) may be provided in multiple forms. For example, the catch (120) may include a first catch (120a) and a second catch (120b). The first catch (120a) and the second catch (120b) may be arranged to face each other. The first catch (120a) and the second catch (120b) may be arranged to be spaced apart from each other. The first catch (120a) and the second catch (120b) may each contact the first surface (71) of the source board (70) and support the first surface (71) of the source board (70). The first catch (120a) and the second catch (120b) may each support the first surface (71) of the source board (70) from opposite sides. As the catch portions (120) are provided in multiple ways, the source board (70) can be more firmly supported by the catch portions (120).

[0120] The number of connecting parts (130) may correspond to the number of hooks (120). For example, the connecting part (130) may include a first connecting part (130a) connecting the first hook (120a) and the holder body (110), and a second connecting part (130b) connecting the second hook (120b) and the holder body (110).

[0121] The first connecting portion (130a) and the second connecting portion (130b) may be arranged to face each other. The first connecting portion (130a) and the second connecting portion (130b) may be arranged parallel to each other. The first connecting portion (130a) and the second connecting portion (130b) may extend in a parallel direction from the holder body (110). The first connecting portion (130a) and the second connecting portion (130b) may be arranged to be spaced apart from each other.

[0122] The first catch (120a) may protrude from the first connecting portion (130a). The first catch (120a) may protrude inwardly from the first connecting portion (130a). The second catch (120b) may protrude from the second connecting portion (130b). The second catch (120b) may protrude inwardly from the second connecting portion (130b). The first catch (120a) and the second catch (120b) may protrude in opposite directions from the first connecting portion (130a) and the second connecting portion (130b), respectively.

[0123] The board holder (100) may include a pressing portion (150) provided to support the source board (70). Specifically, the pressing portion (150) may support the other side of the source board (70) facing the bottom chassis (13). The pressing portion (150) may contact the other side of the source board (70) facing the bottom chassis (13) to support the other side of the source board (70). Hereinafter, the other side of the source board (70) facing the bottom chassis (13) is referred to as a second side (72). The second side (72) of the source board (70) may be defined as one side of the source board (70) adjacent to the holder body (110).

[0124] When the source board (70) is mounted on the board holder (100), the first side (71) of the source board (70) may be in contact with the catch (120), and the second side (72) of the source board (70) may be in contact with the pressing part (150). In other words, the first side (71) of the source board (70) may be supported by the catch (120), and the second side (72) may be supported by the pressing part (150). Therefore, when the source board (70) is mounted on the board holder (100), the distance between the catch (120) and the pressing part (150) may correspond to the thickness of the source board (70). The thickness of the source board (70) may be defined as the distance between the first side (71) and the second side (72).

[0125] Meanwhile, the thickness of the source board (70) can be designed in various ways. If the distance between the catch (120) and the pressurizing portion (150) is always maintained constant, source boards (70) of various thicknesses may not be mounted on the board holder (100). Therefore, depending on how the thickness of the source board (70) is designed, the shape of the board holder (100) may also need to be designed differently. This may increase the design cost of components such as the board holder (100) and reduce the efficiency of the manufacturing process. In addition, if the distance between the catch (120) and the pressurizing portion (150) does not correspond to the thickness of the source board (70), there is a possibility that the board holder (100) may not be able to firmly fix the source board (70).

[0126] To solve this problem, the pressurizing portion (150) may be arranged to press the second side (72) of the source board (70) toward the catch (120). In other words, the pressurizing portion (150) may be arranged to press the second side (72) of the source board (70) in a direction away from the bottom chassis (13).

[0127] The pressing part (150) may be provided to be movable with respect to the holder body (110). The pressing part (150) may be movably supported on the holder body (110). The pressing part (150) may be provided to be movable with respect to the holder body (110) and may press the second surface (72) of the source board (70) toward the catch (120). The pressing part (150) may be provided to be elastically deformed when an external force is applied thereto. The pressing part (150) may be movable with respect to the holder body (110) as the pressing part (150) is elastically deformed when an external force is applied thereto. The pressing part (150) may be connected to the holder body (110) and may be provided to be movable with respect to the holder body (110) when elastically deformed.

[0128] The pressurizing member (150) may include an elastic material so that it can be elastically deformed when an external force is applied. For example, the pressurizing member (150) may include various elastic materials such as a plastic material.

[0129] The pressurizing portion (150) may include a fixed end (151) connected to the holder body (110) and a free end (152) movable with respect to the holder body (110). The free end (152) may be opposite to the fixed end (151). The fixed end (151) may be one end of the pressurizing portion (150) connected to the holder body (110) and fixed with respect to the holder body (110), and the free end (152) may be the other end of the pressurizing portion (150) opposite to the fixed end (151) and separated from the holder body (110) and movable with respect to the holder body (110). The pressurizing portion (150) may extend from the fixed end (151) to the free end (152).

[0130] For example, the board holder (100) may include a gap (160) formed between the free end (152) and the holder body (110). The gap (160) may be formed in a shape in which a portion between the free end (152) and the holder body (110) is cut off. By the gap (160), the pressurizing portion (150) is connected to the holder body (110) at the fixed end (151), but is spaced apart from the holder body (110) at the free end (152), so that the free end (152) can move with respect to the holder body (110). Accordingly, when an external force is applied, the free end (152) can move with respect to the holder body (110), and the pressurizing portion (150) can be elastically deformed by the external force.

[0131] The second side (72) of the source board (70) can be pressed by the free end (152). The free end (152) is provided to be movable with respect to the holder body (110), so as to press the second side (72) of the source board (70). In response to this, when the source board (70) is mounted on the board holder (100), the free end (152) can be pressed by the second side (72) of the source board (70), and thereby the pressing portion (150) can be elastically deformed so that the free end (152) moves in a direction closer to the bottom chassis (13).

[0132] The pressurizing portion (150) may further include a support protrusion (153) provided on the free end (152) and protruding toward the source board (70) to support the source board (70). The support protrusion (153) may pressurize the second surface (72) of the source board (70) as the free end (152) moves. In addition, the pressurizing portion (150) may be elastically deformed as the support protrusion (153) is pressed by the source board (70). With this configuration, the pressurizing portion (150) may pressurize and support the source board (70) more efficiently.

[0133] For example, the support protrusion (153) may be formed in a convex curved shape or an approximately dome shape.

[0134] The pressurizing portion (150) may extend from the fixed end (151) to the free end (152) in a direction away from the bottom chassis (13). The pressurizing portion (150) may extend in an inclined manner from the fixed end (151) to the free end (152) so as to become farther away from the bottom chassis (13). In other words, the pressurizing portion (150) may extend from the fixed end (151) to the free end (152) in a direction closer to the engaging portion (120). The direction in which the pressurizing portion (150) extends from the fixed end (151) to the free end (152) may be inclined with respect to the holder body (110). In this case, as an example, the distance between the free end (152) and the bottom chassis (13) may be shorter than the distance between the engaging portion (120) and the bottom chassis (13). When the source board (70) is not mounted on the board holder (100), the inclination angle of the pressing portion (150) with respect to the bottom chassis (13) or holder body (110) is the largest, and as the thickness of the source board (70) mounted on the board holder (100) increases, the inclination angle of the pressing portion (150) may gradually decrease.

[0135] Referring to FIGS. 9 to 11, the relative position of the pressing portion (150) with respect to the holder body (110) may vary depending on the thickness of the source board (70) mounted on the board holder (100). For example, as shown in FIG. 10, when a source board (70A) having a first thickness (t1) is mounted on the board holder (100), the distance (d1) by which the free end (152) moves by being pressed by the source board (70A) may be longer than, as shown in FIG. 11, when a source board (70B) having a second thickness (t2) thicker than the first thickness (t1) is mounted on the board holder (100), the distance (d2) by which the free end (152) moves by being pressed by the source board (70B) may be longer. That is, the relative position of the pressing portion (150) with respect to the holder body (110) may vary depending on the thickness of the source board (70), and the distance between the holding portion (120) and the pressing portion (150) may vary.

[0136] For example, when the pressurized portion (150) is elastically deformed to the maximum, the direction in which the pressurized portion (150) extends from the fixed end (151) to the free end (152) may be almost parallel to the holder body (110) and the bottom chassis (13) (see FIG. 11).

[0137] As the pressing part (150) is provided to be movable with respect to the holder body (110) and is provided to press the source board (70) toward the catch (120), the distance between the catch (120) and the pressing part (150) can be varied in accordance with the thickness of the source board (70). Accordingly, the board holder (100) can fix source boards (70) of various thicknesses to the bottom chassis (13). Since it is possible to fix source boards (70) of various thicknesses to the bottom chassis (13) with only a single type of board holder (100), it is possible to reduce production costs such as the cost of manufacturing the product mold. In addition, the source board (70) can be fixed more firmly to the bottom chassis (13) by using such a board holder (100).

[0138] For example, the board holder (100) may be configured to allow a source board (70) having a thickness of approximately 0.6 mm or more and 1.2 mm or less to be mounted thereon. For example, the board holder (100) may be configured such that the distance between the support protrusion (153) of the pressing portion (150) and the catch portion (120) varies within a range of approximately 0.45 mm or more and 1.5 mm or less as the pressing portion (150) is elastically deformed.

[0139] The pressing unit (150) may be provided in multiple forms. For example, the pressing unit (150) may include a first pressing unit (150a) and a second pressing unit (150b). The first pressing unit (150a) and the second pressing unit (150b) may each contact the second surface (72) of the source board (70) to support the second surface (72) of the source board (70). The first pressing unit (150a) and the second pressing unit (150b) may each press the second surface (72) of the source board (70). The first pressing unit (150a) and the second pressing unit (150b) may press the second surface (72) of the source board (70) toward the first catch (120a) and the second catch (120b), respectively. The first pressurizing portion (150a) and the second pressurizing portion (150b) may have shapes that are opposite to each other and symmetrical to each other.

[0140] The first pressurizing portion (150a) and the second pressurizing portion (150b) can each be connected to the holder body (110). The first pressurizing portion (150a) and the second pressurizing portion (150b) can each be movably supported on the holder body (110).

[0141] The first pressurizing portion (150a) and the second pressurizing portion (150b) may be positioned spaced apart from each other. For example, the first pressurizing portion (150a) may be connected to one side of the edge of the holder body (110), and the second pressurizing portion (150b) may be connected to the other side of the edge of the holder body (110).

[0142] The first pressurizing portion (150a) and the second pressurizing portion (150b) may be arranged to face each other. The direction in which the first engaging portion (120a) and the second engaging portion (120b) face each other may be different from the direction in which the first pressing portion (150a) and the second pressing portion (150b) face each other. For example, when the first engaging portion (120a) and the second engaging portion (120b) face each other in the first direction, the first pressing portion (150a) and the second pressing portion (150b) may face each other in the second direction that is orthogonal to the first direction. However, in contrast to this, the first direction in which the first catch portion (120a) and the second catch portion (120b) face each other and the second direction in which the first pressure portion (150a) and the second pressure portion (150b) face each other may be different from each other but may not be orthogonal. Alternatively, in contrast to this, the first direction and the second direction may be parallel to each other.

[0143] The first pressurizing portion (150a) can extend from a first fixed end (151) connected to the holder body (110) to a first free end (152) opposite the first fixed end (151) and movable with respect to the holder body (110). Similarly, the second pressurizing portion (150b) can extend from a second fixed end (151) connected to the holder body (110) to a second free end (152) opposite the second fixed end (151) and movable with respect to the holder body (110).

[0144] The first pressurizing portion (150a) and the second pressurizing portion (150b) may be formed to be opposite to each other. Specifically, the direction in which the first pressurizing portion (150a) extends from the first fixed end (151) to the first free end (152) and the direction in which the second pressurizing portion (150b) extends from the first fixed end (151) to the first free end (152) may be opposite to each other.

[0145] The first fixed end (151) of the first pressurizing portion (150a) may be closer to the first catch portion (120a) among the first catch portion (120a) and the second catch portion (120b), and the second fixed end (151) of the second pressurizing portion (150b) may be closer to the second catch portion (120b) among the first catch portion (120a) and the second catch portion (120b).

[0146] In addition, the first free end (152) of the first pressurizing portion (150a) may be closer to the second engaging portion (120b) among the first engaging portion (120a) and the second engaging portion (120b), and the second free end (152) of the second pressurizing portion (150b) may be closer to the first engaging portion (120a) among the first engaging portion (120a) and the second engaging portion (120b).

[0147] In this case, the first free end (152) of the first pressurizing portion (150a) can press the source board (70) in a direction that is more biased toward the second catch portion (120b) among the first catch portion (120a) and the second catch portion (120b). In addition, the second free end (152) of the second pressurizing portion (150b) can press the source board (70) in a direction that is more biased toward the first catch portion (120a) among the first catch portion (120a) and the second catch portion (120b).

[0148] By means of a structure including the first pressurizing portion (150a) and the second pressurizing portion (150b) in this way, the source board (70) can be more efficiently pressed and supported by the first pressurizing portion (150a) and the second pressurizing portion (150b). In addition, the source board (70) can be more well-balanced by the first pressurizing portion (150a) and the second pressurizing portion (150b) on the inside of the board holder (100).

[0149] However, unlike what has been described above, each of the first fixed end (151) and the first free end (152) of the first pressurizing portion (150a) may be closer to the first engaging portion (120a) among the first engaging portion (120a) and the second engaging portion (120b). In addition, each of the second fixed end (151) and the second free end (152) of the second pressurizing portion (150b) may be closer to the second engaging portion (120b) among the first engaging portion (120a) and the second engaging portion (120b).

[0150] In this way, the board holder (100) can be configured to allow source boards (70) of various thicknesses to be mounted, including the catch (120) and the pressurizing portion (150). Meanwhile, the space where the source board (70) is positioned within the board holder (100) can be formed between the catch (120) and the pressurizing portion (150). The space where the source board (70) is positioned within the board holder (100) can be opened on the side opposite to the bottom chassis (13), but some areas may be blocked by the catch (120). Therefore, in the process of mounting the source board (70) to the board holder (100), when the source board (70) is to be introduced into the board holder (100) in a direction approximately perpendicular to the bottom chassis (13), a portion of the source board (70) may be interfered with by the catch (120). That is, the process of mounting the source board (70) to the board holder (100) may not be easy.

[0151] In addition, when the source board (70) is mounted on the board holder (100), the first side (71) of the source board (70) is in contact with the catch (120) and the second side (72) is in contact with the pressurizing side (150), so that the source board (70) is restrained on the inside of the board holder (100). Therefore, when the source board (70) is to be separated from the board holder (100) for reasons such as repair, inspection, or replacement of the source board (70), it may not be easy to separate it.

[0152] To solve this problem, the catch (120) may be provided to be movable with respect to the holder body (110). Specifically, the catch (120) may be provided to be movable with respect to the holder body (110) when an external force is applied to the catch (120). The catch (120) may be supported movably with respect to the holder body (110) when an external force is applied to the catch (120).

[0153] The catch (120) may be provided so as to be movable relative to the holder body (110) by elastic deformation when an external force is applied. The connecting portion (130) may be provided so as to be elastically deformable when an external force is applied to the catch (120), and as the connecting portion (130) is elastically deformed, the catch (120) may be movable relative to the holder body (110).

[0154] In detail, the connecting portion (130) may be provided to bend outward when an external force is applied to the catch portion (120) in a direction toward the holder body (110). In other words, the connecting portion (130) may be provided to bend outward when an external force is applied to the catch portion (120) in a direction toward the bottom chassis (13). As described above, the space in which the source board (70) is positioned within the board holder (100) is formed inward with respect to the connecting portion (130), and since the catch portion (120) protrudes inward from the connecting portion (130), when the connecting portion (130) is bent outward, the catch portion (120) moves outward, thereby allowing the internal space of the board holder (100) to be opened more widely.

[0155] The first connecting portion (130a) may be provided to be elastically deformed when an external force is applied to the first engaging portion (120a). The first connecting portion (130a) may be provided to be elastically deformed so that when an external force is applied to the first engaging portion (120a) in a direction toward the holder body (110) (or the bottom chassis (13)), the first engaging portion (120a) moves in a direction away from the second engaging portion (120b). With this structure, the first engaging portion (120a) can move in a direction away from the second engaging portion (120b) when pressed in a direction toward the holder body (110) (or the bottom chassis (13)).

[0156] The second connecting portion (130b) may be provided to be elastically deformed when an external force is applied to the second engaging portion (120b). The second connecting portion (130b) may be provided to be elastically deformed so that when an external force is applied to the second engaging portion (120b) in a direction toward the holder body (110) (or the bottom chassis (13)), the second engaging portion (120b) moves in a direction away from the first engaging portion (120a). With this structure, the second engaging portion (120b) can move in a direction away from the first engaging portion (120a) when pressed in a direction toward the holder body (110) (or the bottom chassis (13)).

[0157] In this way, the first connecting portion (130a) and the second connecting portion (130b) can be bent outward when the first catch portion (120a) and the second catch portion (120b) are pressed toward the holder body (110) (or bottom chassis (13)), and the first catch portion (120a) and the second catch portion (120b) can move away from each other so that the internal space of the board holder (100) can be opened more widely.

[0158] The connecting portion (130) may include an elastic material to enable elastic deformation when an external force is applied. For example, the connecting portion (130) may include various elastic materials such as a plastic material.

[0159] A connecting hole (131) may be formed on a portion of the side where the connecting portion (130) of the board holder (100) and the holder body (110) are connected. The connecting hole (131) may be formed on a portion of the side where each of the first connecting portion (130a) and the second connecting portion (130b) is connected to the holder body (110). The connecting hole (131) may be formed in a shape where a portion of one end of the connecting portion (130) adjacent to the holder body (110) passes through. As the connecting hole (131) is formed, the connecting portion (130) can be elastically deformed more efficiently. In addition, as the connecting hole (131) is formed, it is easy to separate the injection molded product from the injection mold in which the portion corresponding to the hook (120) and the connecting portion (130) are formed, so that the efficiency of the manufacturing process can be improved.

[0160] The catch (120) may include an inclined surface (121). The inclined surface (121) may be provided on one side of the catch (120) facing the outside of the board holder (100). When the source board (70) is mounted on the board holder (100), the inclined surface (121) may be positioned opposite to the first side (71) of the source board (70). Therefore, when the source board (70) enters the board holder (100), the inclined surface (121) may be pressed by the source board (70).

[0161] The engaging portion (120) may include an inclined surface (121) that extends inwardly as it gets closer to the holder body (110). In other words, the inclined surface (121) may extend inwardly as it gets closer to the bottom chassis (13). The inclined surface (121) may extend so that the length protruding from the connecting portion (130) increases as it gets closer to the holder body (110) (or the bottom chassis (13)).

[0162] By this structure, the inclined surface (121) can guide the source board (70) to enter the interior of the board holder (100). In addition, by this structure, as the source board (70) enters the interior of the board holder (100), the degree of pressure applied by the source board (70) increases, so that the degree of bending of the connecting portion (130) outward can increase, and the source board (70) can easily enter the interior of the board holder (100).

[0163] For example, the inclined surface (121), such as the inclined surface (121) of the first catch portion (120a), may have the shape of a flat surface extending in one direction. Or, for example, the inclined surface (121), such as the inclined surface (121) of the second catch portion (120b), may have a curved shape. In particular, the inclined surface (121), such as the inclined surface (121) of the second catch portion (120b), may have the shape of a convex curved surface.

[0164] However, the shape of the catch (120) is not limited to that described above.

[0165] By this structure, in the process of mounting the source board (70) on the board holder (100), the space inside the board holder (100) is opened wider by pressing the catch (120) using the source board (70), so that the source board (70) can be easily mounted in the board holder (100). Furthermore, by this structure, it is possible to mount the source board (70) on the board holder (100) by entering the board holder (100) in a direction approximately perpendicular to the bottom chassis (13).

[0166] Therefore, when utilizing the structure of the board holder (100) as described above, the process of mounting the source board (70) on the bottom chassis (13) can be performed efficiently and easily. This makes it possible to shorten the product manufacturing time and reduce manufacturing costs. Furthermore, when utilizing the structure of the board holder (100) as described above, it is more advantageous to implement a system that automates the process of mounting the source board (70) on the bottom chassis (13) by machine.

[0167] The board holder (100) may include a guide portion (140) provided to guide the source board (70) into the inside of the board holder (100). The guide portion (140) may be connected to the connection portion (130). The guide portion (140) may extend from one end of the connection portion (130) opposite the holder body (110). The guide portion (140) may extend from one end of the connection portion (130) opposite the bottom chassis (13). Specifically, the guide portion (140) may extend outwardly as it moves away from the connection portion (130). The extension direction of the guide portion (140) may be inclined with respect to the extension direction of the connection portion (130).

[0168] To correspond to the number of connecting portions (130), a plurality of guide portions (140) may be provided. For example, the guide portion (140) may include a first guide portion (140a) connected to the first connecting portion (130a) and a second guide portion (140b) connected to the second connecting portion (130b). The first guide portion (140a) may extend from the first connecting portion (130a) in a direction away from the holder body (110) and the second guide portion (140b). The second guide portion (140b) may extend from the second connecting portion (130b) in a direction away from the holder body (110) and the first guide portion (140a).

[0169] In this way, since the board holder (100) includes the guide portion (140), the process of mounting the source board (70) to the board holder (100) can be performed more efficiently and easily.

[0170] Each component of the board holder (100), such as the holder body (110), connecting portion (130), catch portion (120), guide portion (140), and pressurizing portion (150) described above, may be formed integrally with each other. For example, the board holder (100) may be formed integrally by injection molding plastic resin.

[0171] FIG. 12 is a cross-sectional view illustrating an example of a process for attaching a board holder to a bottom chassis of a display device according to one embodiment of the present disclosure. FIG. 13 is a cross-sectional view illustrating a board holder attached to a bottom chassis by the process of FIG. 12.

[0172] Referring to FIGS. 12 and 13, an example of a method of attaching a board holder (100) to a bottom chassis (13) is described.

[0173] Referring to FIGS. 12 and 13, the board holder (100) can be coupled to the edge portion (13a) of the bottom chassis (13). A coupling hole (13b) can be formed in the edge portion (13a) of the bottom chassis (13), and the board holder (100) can be coupled to the bottom chassis (13) by the first chassis coupling portion (111) and the second chassis coupling portion (112) penetrating the coupling hole (13b).

[0174] More specifically, as illustrated in FIG. 12, the first chassis coupling portion (111) may first be positioned to penetrate the coupling hole (13b) and then may be hooked to the coupling hole (13b). Thereafter, the second chassis coupling portion (112) may be positioned to penetrate the coupling hole (13b). Through these steps, the board holder (100) may be coupled to the bottom chassis (13), as illustrated in FIG. 13.

[0175] As shown in FIGS. 12 and 13, the board holder (100) can be positioned so that the first chassis coupling portion (111) is closer to the lower edge of the bottom chassis (13) than the second chassis coupling portion (112).

[0176] In one embodiment, the edge portion (13a) of the bottom chassis (13) may be formed to be inclined with respect to the display panel (20). Under this structure, when the process of coupling the board holder (100) to the bottom chassis (13) is performed while the rear surface of the bottom chassis (13) is positioned so as to face the work surface, the first chassis coupling portion (111) may pass through the coupling hole (13b) downward and be caught in the coupling hole (13b). From the perspective of a worker performing the process of coupling the board holder (100) to the bottom chassis (13), the method of allowing the first chassis coupling portion (111) to pass through below the coupling hole (13b) and be caught in the coupling hole (13b) is more convenient than the method of allowing the first chassis coupling portion (111) to pass through above the coupling hole (13b) and be caught in the coupling hole (13b), thereby improving the efficiency of the manufacturing process.

[0177] Of course, as described above, the frame (13a) of the bottom chassis (13) may be formed parallel to the display panel (20).

[0178] The method of attaching the board holder (100) to the bottom chassis (13) described above with reference to FIGS. 12 and 13 is only an example, and the idea of ​​the present disclosure is not limited thereto.

[0179] FIG. 14 is a drawing illustrating an example of a process for mounting a source board on a board holder of a display device according to one embodiment of the present disclosure. FIG. 15 is a drawing illustrating a source board mounted on a board holder according to the process of FIG. 14.

[0180] Referring to FIGS. 14 and 15, an example of a method for mounting a source board (70) on a board holder (100) is described.

[0181] Referring to FIGS. 14 and 15, the source board (70) can be mounted on a board holder (100) fixed to the bottom chassis (13). More specifically, as illustrated in FIG. 14, the process of mounting the source board (70) on the board holder (100) can be performed through a process in which the source board (70) is not caught by the first catch (120a) and the second catch (120b) at the same time, but is first caught by the second catch (120b) and then caught by the first catch (120a). The board holder (100) can be arranged such that the second catch (120b) is closer to the lower edge of the bottom chassis (13) than the first catch (120a).

[0182] In one embodiment, the edge portion (13a) of the bottom chassis (13) may be formed to be inclined with respect to the display panel (20). Under this structure, when the process of mounting the source board (70) on the board holder (100) is performed with the rear surface of the bottom chassis (13) facing upwards on the worktable, one side of the source board (70) is inserted into the inner side of the second catch portion (120b) so that the source board (70) is first caught by the second catch portion (120b) located below, and then the other side of the source board (70) is inserted into the inner side of the first catch portion (120a) so that the source board (70) is also caught by the first catch portion (120a) by pressing the first catch portion (120a) located above onto the source board (70). This may be more convenient for the worker and may improve efficiency in the manufacturing process.

[0183] Unlike the inclined surface (121) of the first catch portion (120a) which has a flat surface shape, the inclined surface (121) of the second catch portion (120b) which is arranged adjacent to the lower edge of the bottom chassis (13) may have a curved surface shape. Accordingly, in the process of first inserting one side of the source board (70) into the inner side of the second catch portion (120b) so that the source board (70) is caught by the second catch portion (120b), one side of the source board (70) can smoothly move along the inclined surface of the first catch portion (120a) and can be efficiently inserted into the inner side of the second catch portion (120b).

[0184] Through these steps, the source board (70) can be mounted on the board holder (100) as shown in FIG. 15.

[0185] Of course, as described above, the frame (13a) of the bottom chassis (13) may be formed parallel to the display panel (20).

[0186] FIG. 16 is a diagram illustrating another example of a process for mounting a source board on a board holder of a display device according to one embodiment of the present disclosure. FIG. 17 is a diagram illustrating a source board mounted on a board holder according to the process of FIG. 16.

[0187] Referring to FIGS. 16 and 17, another example of a method of mounting a source board (70) on a board holder (100) is described.

[0188] Referring to FIGS. 16 and 17, the source board (70) can be mounted on a board holder (100) fixed to the bottom chassis (13). At this time, unlike what was described with reference to FIGS. 14 and 15, the process of mounting the source board (70) on the board holder (100) can be performed through a process in which the source board (70) is caught on the first catch (120a) and the second catch (120b) almost simultaneously.

[0189] More specifically, as illustrated in FIG. 16, the source board (70) can move in a direction approximately perpendicular to the edge portion (13a) of the bottom chassis (13) to the holder body (110) and enter the inside of the board holder (100). The source board (70) can enter the inside of the board holder (100) and press the first catch portion (120a) and the second catch portion (120b) almost simultaneously. As the source board (70) presses the first catch portion (120a) and the second catch portion (120b), the first connecting portion (130a) and the second connecting portion (130b) can be elastically deformed outward almost simultaneously, and the source board (70) can be inserted into the inside of the first catch portion (120a) and the second catch portion (120b).

[0190] Through these steps, the source board (70) can be mounted on the board holder (100) as shown in FIG. 17.

[0191] In the above, an embodiment in which a source board (70) is fixed to a bottom chassis (13) by a board holder (100) has been described in detail with reference to FIGS. 1 to 17. However, the spirit of the present disclosure is not limited thereto, and the structure described above can be modified and applied to a structure for fixing various circuit boards, including a main board (50) and a power supply board (60), to a bottom chassis (13) by using a board holder (100).

[0192] In addition, in the above embodiment, the board holder (100) is placed on the edge portion (13a) of the bottom chassis (13), but the board holder (100) may be placed on various positions on the bottom chassis (13) depending on the type of circuit board to be fixed to the bottom chassis (13) by the board holder (100) and its designed position.
