Description

  The present invention relates to an optical member holding structure, a display device, and a television receiver.

  In recent years, display elements of image display devices such as television receivers are shifting from conventional cathode ray tubes to thin display panels such as liquid crystal panels and plasma display panels, which enables thinning of image display devices. Since the liquid crystal panel used for the liquid crystal display device does not emit light by itself, a backlight device is separately required as a lighting device, and the backlight device is roughly classified into a direct type and an edge light type according to the mechanism. In order to further reduce the thickness of the liquid crystal display device, it is preferable to use an edge light type backlight device, and an example described in Patent Document 1 below is known.

JP 2009-58915 A

Patent Document 1 described above describes a liquid crystal display device in which a frame is narrowed by attaching a fixing screw for attaching a back cover to a slide mounting bracket.
However, in Patent Document 1, since the slide mounting bracket is arranged between the front cover and the liquid crystal panel, the frame is made larger by the amount of the slide mounting bracket, thereby further narrowing the frame. It was a hindrance above.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to achieve a narrow frame.

  The optical member holding structure of the present invention is arranged in a shape that follows a plate-shaped optical member, a chassis having a plate-like portion along the plate surface of the optical member, and an outer peripheral end portion of the optical member, and the chassis. A frame having a clamping part for clamping at least a part of an outer peripheral end part of the optical member between the optical member and the chassis, wherein the optical member and the chassis are plate surfaces of the optical member and the plate-like part. The plate-like portion that sandwiches the optical member between the opening that can be inserted along the direction along the direction and the sandwiching portion is opposed to the side opposite to the optical member side with an interval. A frame having at least a frame main body having a receiving portion; a frame attachment member attached to be arranged on the opposite side of the plate-like portion side with respect to the receiving portion; the frame attachment member and the plate-like portion Between Arranged in the form of, and a spacer portion for holding the interval is spaced between the plate portion and the receiving portion.

  As described above, when the optical member and the chassis are inserted into the opening of the frame main body along the direction along the plate surface of the optical member and the plate-like portion, the optical member and the chassis are optically connected between the holding portion of the frame and the plate-like portion of the chassis. By adopting a configuration in which at least a part of the outer peripheral end portion of the member is clamped, a conventionally used slide mounting bracket is not required, and accordingly, a narrow frame can be achieved.

In addition, since the receiving portion of the frame body is arranged to face the plate-like portion of the chassis with an interval on the opposite side to the optical member side, the optical member and the chassis are opened to the opening of the frame body. When performing the operation of inserting into the portion, the optical member and the chassis can easily enter between the receiving portion of the frame body and the sandwiching portion, thereby improving the workability related to the insertion operation. Moreover, in addition to the frame mounting member being mounted so as to be disposed on the opposite side of the chassis from the plate-like part side, the spacer is interposed between the frame mounting member and the plate-like part. Since the gap between the receiving portion and the plate-like portion is maintained by arranging the portion, the optical member held between the plate-like portion and the holding portion is less likely to rattle. Is done.
As described above, after narrowing the frame, it is possible to achieve both improvement in workability related to insertion work of the optical member and the chassis and suppression of rattling of the optical member.

As an embodiment of the optical member holding structure of the present invention, the following configuration is preferable.
(1) A receiving portion fixing member for fixing the frame mounting member to the receiving portion is provided. If it does in this way, the space | interval vacated between the plate-shaped part of a chassis and the receiving part of a frame main body is stably hold | maintained by fixing a frame attachment member with respect to a receiving part with the fixing member for receiving parts. Therefore, the optical member is hardly rattled between the plate-like portion and the sandwiching portion, and can be stably sandwiched.

(2) The receiving part and the fixing member for the receiving part are arranged closer to the end side of the plate-like part than the spacer part. The frame main body has a holding portion for holding at least a part of the outer peripheral end portion of the optical member with the plate-like portion in addition to the receiving portion where the frame mounting member is fixed by the receiving portion fixing member. Therefore, as described above, the receiving portion and the fixing member for the receiving portion are arranged on the end side of the plate-like portion rather than the spacer portion, so that it is compared with the case where it is arranged on the center side of the plate-like portion rather than the spacer portion. And a receiving part and a frame main body can be kept small.

(3) Whereas the receiving portion is formed to extend along the end portion of the plate-like portion, a plurality of the receiving portion fixing members are intermittent in the extending direction of the receiving portion. Are arranged side by side. If it does in this way, a plurality of receiving part fixing members for fixing the frame attaching member to the receiving part will be arranged intermittently side by side in the extending direction of the receiving part. It can be more stably fixed to the receiving part. Thereby, since the space | interval vacated between a receiving part and a plate-shaped part is hold | maintained more stably, it is hard to rattle an optical member between a plate-shaped part and a clamping part, and is clamped more stably. can do.

(4) The plurality of receiving portion fixing members are arranged so as to sandwich the spacer portion in the extending direction of the receiving portion. After performing the operation of inserting the optical member and the chassis into the opening of the frame body, when the frame mounting member is fixed to the receiving portion by a plurality of receiving portion fixing members, the plate-like portion is attached to the frame mounting member via the spacer portion. By being supported by the above, it is possible to maintain a state in which a space is provided between the plate-like portion and the receiving portion. Since the plurality of receiving portion fixing members are arranged so as to sandwich the spacer portion in the extending direction of the receiving portion, the plate-like portion is better supported by the frame mounting member via the spacer portion, and thus the plate-like portion. It is possible to more stably keep the space between the receiving portion and the receiving portion.

(5) The spacer portion is provided on the plate-like portion, and includes a spacer fixing member that fixes the frame mounting member to the spacer portion. After performing the work of inserting the optical member and the chassis into the opening of the frame body, if the frame mounting member is attached to the receiving portion on the side opposite to the plate-like portion side of the chassis, the plate-like portion becomes the spacer. By being supported by the frame mounting member via the portion, the plate-like portion and the receiving portion are maintained in a state where a gap is provided. Since the frame mounting member is fixed to the spacer portion provided on the plate-like portion by the spacer fixing member, deformation such as bending is unlikely to occur in the portion of the frame mounting member that overlaps the spacer portion. Thereby, a plate-shaped part is supported more favorably by a frame attachment member via a spacer part, and can maintain the space | interval opened between a plate-shaped part and a receiving part more stably.

(6) The spacer portion is arranged closer to the center of the plate-like portion than the receiving portion. After performing the work of inserting the optical member and the chassis into the opening of the frame body, if the frame mounting member is attached to the receiving portion on the side opposite to the plate-like portion side of the chassis, the plate-like portion becomes the spacer. By being supported by the frame mounting member via the portion, the plate-like portion and the receiving portion are maintained in a state where a gap is provided. Here, the center side of the plate-like portion and the optical member tends to be easily deformed, such as bending, compared to the end side. On the other hand, since the center side of the plate-like part is supported by the frame mounting member via the spacer part by arranging the spacer part on the center side of the plate-like part from the receiving part as described above, the plate-like part Further, deformation such as bending is less likely to occur in the optical member.

(7) The said spacer part shall have a dimension about the direction orthogonal to the plate surface of the said plate-shaped part larger than the same dimension of the said receiving part. For example, even when the plate-like part and the frame mounting member are flat in the direction along the plate surface of the plate-like part, the spacer in the direction perpendicular to the plate surface of the plate-like part is larger than the same dimension of the receiving part. By interposing the portion between the plate-like portion and the frame mounting member, it is possible to keep a state in which a space is provided between the receiving portion and the plate-like portion. Thereby, it becomes difficult to make the shapes of the plate-like portion and the frame mounting member difficult and simple.

(8) The frame mounting member is arranged so as to cover the plate-like portion, the receiving portion, and the spacer portion from the side opposite to the optical member side. If it does in this way, it can prevent that a plate-shaped part, a receiving part, and a spacer part are exposed to the exterior on the opposite side to the optical member side. Moreover, regarding the spacer portion interposed between the frame attachment member and the plate-like portion, the degree of freedom of arrangement in the direction along the plate surface of the plate-like portion can be increased.

(9) The spacer portion is a separate component from the chassis and the frame mounting member. If the spacer portion is integrally provided on either the chassis or the frame mounting member, the chassis or frame mounting member becomes a dedicated part having the spacer portion, whereas the spacer portion is replaced with the chassis and the frame as described above. By using a separate component from the mounting member, the chassis and the frame mounting member can be shared with other types of lighting devices that do not require the spacer portion.

(10) Provided with a cushioning material attached to the clamping portion of the frame to cushion the optical member. In this way, when the optical member and the chassis are inserted into the opening of the frame body, the optical member is buffered by the buffer material, so that it is difficult to cause a situation where the optical member is damaged. .

(11) The frame body includes a pair of first extending portions that extend along a pair of side portions that form opposite sides of the three side portions included in the outer peripheral end portion of the optical member, and the pair of A second extension portion extending along a side portion that is connected to an end portion on the same side of the first extension portion and is sandwiched between the pair of side portions of the three side portions of the optical member; And the opening is provided between the ends of the pair of first extending portions opposite to the second extending portion. In this way, when the optical member and the chassis are inserted into the opening provided between the ends of the pair of first extending portions opposite to the second extending portion side, the pair of first extending portions The insertion operation is guided by. Thereby, the insertion work of an optical member and a chassis is smoothed, and it is further excellent in workability | operativity.

  The display device of the present invention includes the above-described optical member holding structure and a display panel included at least in the optical member. According to such a display device, the design of the display device can be improved by narrowing the frame.

As an embodiment of the display device of the present invention, the following configuration is preferable.
(1) Illumination comprising at least a light source housed in a space provided between the chassis and the frame, and a light guide plate that is at least included in the optical member and guides light from the light source. An apparatus is provided, and outer peripheral ends of the display panel and the light guide plate are sandwiched between the plate-like portion of the chassis and the sandwiching portion of the frame. In this way, it is possible to assemble the display panel, the light guide plate, and the chassis so as to be collectively inserted into the opening of the frame body in a state where they are overlapped with each other. It will be a thing.

  The television receiver of the present invention includes the display device described above. According to such a television receiver, the design of the television receiver can be improved by narrowing the frame.

  According to the present invention, it is possible to suitably reduce the frame.

Among these, the liquid crystal panel 11 is assembled to the liquid crystal display device 10 in a posture in which the display surface for displaying an image faces the front side, and uses the illumination light supplied from the backlight device 12 arranged on the back side. The “optical member” is capable of displaying an image on the display surface. The television receiver TV includes at least a tuner substrate T capable of receiving a television image signal in addition to the liquid crystal display device 10 described above, and can display a television image on the display surface of the liquid crystal panel 11. Is done. The tuner board T is accommodated in a space provided between the backlight device 12 and the back cabinet 14.

  As shown in FIGS. 1 and 2, the liquid crystal panel 11 has a horizontally long rectangular (rectangular) shape in plan view, and a pair of glass substrates excellent in translucency are separated from each other by a predetermined gap. And the liquid crystal is sealed between both substrates. The liquid crystal panel 11 is incorporated in the liquid crystal display device 10 in a posture in which the long side direction coincides with the X-axis direction, the short side direction coincides with the Y-axis direction, and the thickness direction coincides with the Z-axis direction. Of the pair of substrates, one substrate (array substrate) has a switching element (for example, TFT) connected to the source wiring and the gate wiring orthogonal to each other, a pixel electrode connected to the switching element, and an orientation. A film or the like is provided, and the other substrate (CF substrate) is a color filter or counter electrode in which colored portions such as R (red), G (green), and B (blue) are arranged in a predetermined arrangement, An alignment film or the like is provided. The liquid crystal panel 11 has a display area (active area) where the display surface is on the center side of the screen and an image can be displayed, and a frame shape (frame shape) which surrounds the display area on the outer peripheral side of the screen. It is divided into a non-display area (non-active area). Note that a pair of front and back polarizing plates are respectively attached to the outer surface sides of the pair of substrates.

  Next, the backlight device 12 will be described. As shown in FIGS. 1 and 4, the backlight device 12 includes a chassis 15 having a plate-like portion 15 a along the plate surface of the liquid crystal panel 11, and an LED 16 (Light Emitting Diode) that is housed in the chassis 15 and serves as a light source. An LED substrate (light source substrate) 17 on which a diode) is mounted, a light guide plate (optical member) 18 that is placed on the plate-like portion 15a and guides light from the LED 16, and the light guide plate 18 and the plate-like portion 15a. And at least a reflection sheet (optical member, reflection member) 19 disposed in a manner interposed therebetween, and an optical sheet (optical member) 20 placed on the light guide plate 18. That is, the backlight device 12 is formed by laminating the optical sheet 20, which is an optical member, the light guide plate 18, and the reflection sheet 19 in order from the front side at a position directly below the liquid crystal panel 11. In FIG. 1, the optical sheet 20 is not shown. The backlight device 12 is provided with an LED board 17 at one end (the front side shown in FIG. 1 and the left side shown in FIG. 4) of the both ends of the long side. Each LED 16 mounted on the liquid crystal panel 11 is unevenly distributed near one end portion on the long side of the liquid crystal panel 11. As described above, the backlight device 12 according to the present embodiment is a one-side incident type edge light type (side light type) that enters the light guide plate 18 only from one side. Below, each component of the backlight apparatus 12 is demonstrated in detail.

  As shown in FIGS. 1, 4 and 6, the chassis 15 is a plate-like portion (bottom plate portion) which is formed in a horizontally-long rectangular shape as viewed from the plane as shown in FIGS. ) 15a and a side plate portion 15b that rises from the end of one long side of the plate-like portion 15a toward the front side. The plate-like portion 15a has a posture in which the long side direction coincides with the X-axis direction, the short side direction coincides with the Y-axis direction, and the plate thickness direction coincides with the Z-axis direction. The long side dimension is substantially the same as or slightly smaller than the long side dimension of the light guide plate 18. Most of the plate-like portion 15a is a light guide plate support portion 15a1 that supports the light guide plate 18 from the back side (the side opposite to the light emitting surface 18a side) together with the reflective sheet 19, whereas the plate-like portion 15a is on the LED substrate 17 side. The end portion is a substrate housing portion 15a2 that bulges to the back side in a stepped shape. Among these, the substrate housing portion 15a2 has a substantially L-shaped cross-section, and is raised from the end portion of the light guide plate support portion 15a1 and rises toward the back side, and the rising tip portion of the rising portion 21 The housing bottom 22 is bent toward the light guide plate support 15a1 and protrudes toward the opposite side. The rising position of the rising portion 21 is located on the opposite side of the LED 16 side from the light incident surface 18b of the light guide plate 18 (to be described later) (near the center of the light guide plate support portion 15a1). The side plate portion 15b is bent and formed so as to rise from the end opposite to the rising portion 21 side in the housing bottom portion 22 constituting the substrate housing portion 15a2 to the front side. The LED board 17 is attached to the side plate portion 15b so as to be in contact with the inner plate surface (the surface facing the light incident surface 18b of the light guide plate 18). That is, it can be said that the side plate portion 15b constitutes a substrate attachment portion to which the LED substrate 17 is attached.

  As shown in FIGS. 4 and 7, the LED 16 has a configuration in which an LED chip is sealed with a resin material on a substrate portion fixed to the LED substrate 17. The LED chip mounted on the substrate unit has one main emission wavelength, and specifically, one that emits blue light in a single color is used. On the other hand, the resin material that seals the LED chip is dispersed and blended with a phosphor that emits a predetermined color when excited by the blue light emitted from the LED chip, and generally emits white light as a whole. It is said. In addition, as the phosphor, for example, a yellow phosphor that emits yellow light, a green phosphor that emits green light, and a red phosphor that emits red light are used in appropriate combination, or any one of them is used. It can be used alone. The LED 16 is a so-called top surface light emitting type in which a surface opposite to the mounting surface with respect to the LED substrate 17 is a main light emitting surface 16a.

  As shown in FIGS. 4 and 7, the LED substrate 17 has an elongated plate shape extending along the long side direction of the chassis 15 (X-axis direction, the longitudinal direction of the light incident surface 18 b of the light guide plate 18). The plate surface is accommodated in the chassis 15 in a posture parallel to the X-axis direction and the Z-axis direction, that is, in a posture orthogonal to the plate surfaces of the liquid crystal panel 11 and the light guide plate 18 (optical sheet 20). That is, the LED substrate 17 has a plate thickness in which the long side direction (length direction) on the plate surface coincides with the X-axis direction, and the short side direction (width direction) coincides with the Z-axis direction, and is further orthogonal to the plate surface. The orientation is the same as the Y-axis direction. The LED substrate 17 is mounted such that the plate surface opposite to the mounting surface 17a on which the LED 16 is mounted is in contact with the inner surface of the side plate portion 15b of the chassis 15, and the end portion on the long side of the light guide plate 18 ( 4 are arranged side by side on the left side shown in FIG. 4 with a predetermined arrangement interval with respect to the light incident surface 18b). Therefore, the alignment direction of the LED 16 and the LED substrate 17 and the light guide plate 18 is substantially the same as the Y-axis direction, and the optical axis in each LED 16, that is, the traveling direction of light having the highest light emission intensity is the Y-axis direction (liquid crystal panel). 11 in the direction parallel to the plate surface).

  As shown in FIGS. 4 and 7, the LED substrate 17 is mounted on the inner surface thereof, that is, the plate surface facing the light guide plate 18 side (the surface facing the light guide plate 18). It is set as the surface 17a. A plurality of LEDs 16 are arranged in a row (linearly) in parallel on the mounting surface 17a of the LED substrate 17 along the length direction (X-axis direction) with a predetermined arrangement interval. That is, it can be said that a plurality of LEDs 16 are intermittently arranged in parallel along the long side direction at one end portion on the long side side of the backlight device 12. Therefore, the alignment direction of the LEDs 16 coincides with the length direction (X-axis direction) of the LED substrate 17 and the light guide plate 18. The interval between the LEDs 16 adjacent to each other in the X-axis direction, which is the arrangement direction of the LEDs 16, that is, the arrangement interval (arrangement pitch) of the LEDs 16 is substantially equal. Further, a wiring pattern (not shown) made of a metal film (such as a copper foil) is provided on the mounting surface 17a of the LED substrate 17 and extends along the X-axis direction and connects adjacent LEDs 16 across the LED 16 group. ) And terminal portions formed at both ends of the wiring pattern are connected to an external LED drive circuit board (not shown) via a wiring member or the like, so that driving power is supplied to each LED 16. It comes to be supplied. The LED drive circuit board is a space provided between the backlight device 12 and the back cabinet 14 together with the above-described tuner board T and panel drive circuit board (not shown) for driving the liquid crystal panel 11. Is housed inside. The base material of the LED substrate 17 is made of a metal such as aluminum, for example, and the above-described wiring pattern (not shown) is formed on the surface thereof via an insulating layer. In addition, as a material used for the base material of the LED board 17, insulating materials, such as a synthetic resin and a ceramic, can also be used.

  The light guide plate 18 is made of a synthetic resin material (for example, acrylic resin such as PMMA or polycarbonate) having a refractive index sufficiently higher than that of air and substantially transparent (excellent translucency). As shown in FIGS. 1 and 4, the light guide plate 18 has a horizontally long rectangular shape in a plan view as in the case of the liquid crystal panel 11 and the chassis 15 and has a plate shape that is thicker than the optical sheet 20. The long side direction on the plate surface coincides with the X-axis direction, the short side direction coincides with the Y-axis direction, and the plate thickness direction orthogonal to the plate surface coincides with the Z-axis direction. The light guide plate 18 is disposed immediately below the liquid crystal panel 11 and the optical sheet 20 in the chassis 15, and one of the outer peripheral end surfaces (the front side shown in FIG. 1, the left side shown in FIG. 4) of the long side Are opposed to the LEDs 16 of the LED substrate 17 arranged at one end of the chassis 15 on the long side. Therefore, the alignment direction of the LED 16 (LED substrate 17) and the light guide plate 18 matches the Y-axis direction, while the alignment direction of the optical sheet 20 (liquid crystal panel 11) and the light guide plate 18 matches the Z-axis direction. It is assumed that both directions are orthogonal to each other. The light guide plate 18 has a function of introducing light emitted from the LED 16 in the Y-axis direction and raising and emitting the light toward the optical sheet 20 (front side) while propagating the light inside. .

  As shown in FIGS. 4 and 7, the light guide plate 18 has a substantially flat plate shape extending along each plate surface of the plate-like portion 15a of the chassis 15 and the optical sheet 20, and the plate surface is X-axis. Direction and the Y-axis direction. Of the pair of front and back plate surfaces of the light guide plate 18, the plate surface facing the front side (the surface facing the optical sheet 20) is a light emitting surface 18 a that emits internal light toward the optical sheet 20 and the liquid crystal panel 11. ing. Of the outer peripheral end surfaces adjacent to the plate surface of the light guide plate 18, among the pair of long side end surfaces that form a longitudinal shape along the X-axis direction (the LED 16 arrangement direction, the LED substrate 17 long side direction), One end face (left side shown in FIG. 4, front side shown in FIG. 7) is opposed to the LED 16 (LED substrate 17) with a predetermined space therebetween, and light emitted from the LED 16 is incident on the end face. It is a light incident surface 18b. Since the light incident surface 18 b is opposed to the LED 16, it can be said that it constitutes an “LED facing end surface (light source facing end surface)”. In contrast, among the outer peripheral end surfaces adjacent to the plate surface of the light guide plate 18, the other three end surfaces excluding the light incident surface 18b (the end surface on the long side opposite to the light incident surface 18b). , And a pair of short side ends) are LED non-facing end faces (light source non-facing end faces) that are not opposed to the LEDs 16. The distances between the light incident surfaces 18b and the respective LEDs 16 facing each other are substantially the same. Further, the light incident surface 18b is a surface parallel to the X-axis direction (the LED 16 arrangement direction) and the Z-axis direction, that is, along the plate surface of the LED substrate 17, and a surface substantially orthogonal to the light emitting surface 18a. Is done. Further, the alignment direction of the LED 16 and the light incident surface 18b coincides with the Y-axis direction and is parallel to the light emitting surface 18a.

  As shown in FIG. 4, the reflection sheet 19 is disposed so as to cover the back side of the light guide plate 18, that is, the opposite plate surface opposite to the light emitting surface 18 a (the surface facing the plate-like portion 15 a of the chassis 15) 18 c. Thus, it is possible to reflect the light emitted from the opposite plate surface 18c to the outside on the back side and rise to the front side. In other words, the reflection sheet 19 is disposed between the plate-like portion 15 a of the chassis 15 and the light guide plate 18. The reflection sheet 19 is slightly larger in size in plan view than the light guide plate 18, and can cover the opposite plate surface 18 c of the light guide plate 18 over almost the entire region. Of this reflection sheet 19, the light incident surface 18b side end (one long side end) of the light guide plate 18 extends outward from the light incident surface 18b, that is, toward the LED 16 side. . By reflecting the light existing in the space between the LED substrate 17 and the light incident surface 18b by the extending portion of the reflection sheet 19, the light incident efficiency on the light incident surface 18b is increased. Can do. Further, on the opposite plate surface 18c of the light guide plate 18, a light reflection pattern (see FIG. 5) is formed of a light reflecting portion for reflecting the light in the light guide plate 18 toward the light output surface 18a. (Not shown) is formed. The light reflecting portion forming the light reflecting pattern is formed by printing a light reflecting material (for example, white ink containing a metal oxide such as titanium oxide) on the opposite plate surface 18c of the light guide plate 18. The distribution density of the dots (area ratio per unit area on the opposite plate surface 18c) is from the end on the light incident surface 18b side of the light guide plate 18 in the Y axis direction to the opposite side. It is formed with a distribution that increases as it approaches the end.

  As shown in FIGS. 4 and 5, the optical sheet 20 has a horizontally long rectangular shape when seen in a plane like the liquid crystal panel 11 and the chassis 15. The optical sheet 20 is placed on the front side (light emitting side) of the light guide plate 18 and is disposed between the liquid crystal panel 11 and the light guide plate 18 so as to transmit light emitted from the light guide plate 18. At the same time, the transmitted light is emitted toward the liquid crystal panel 11 while giving a predetermined optical action. The optical sheet 20 has a sheet shape thinner than the light guide plate 18 and a plurality of sheets (two in the present embodiment) are arranged on the light emitting surface 18 a of the light guide plate 18. Specific types of the optical sheet 20 include, for example, a diffusion sheet, a lens sheet, a reflective polarizing sheet, and the like, which can be appropriately selected and used. On the front side of the optical sheet 20 as described above, the liquid crystal panel 11 described above is directly placed. That is, the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19 that are included in the liquid crystal display device 10 according to the present embodiment and constitute an optical member are directly stacked without interposing other members. In this state, it is sandwiched and held between a frame 13 and a chassis 15 (back cabinet 14) described below. As described above, the liquid crystal display device 10 according to this embodiment includes the optical member holding structure LH that holds the optical members such as the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19 between the frame 13 and the chassis 15. It can be said that it has.

  Next, the frame 13 will be described in detail. The frame 13 is made of metal (for example, aluminum), and as shown in FIGS. 1 and 7, between the plate-like portion 15 a (light guide plate support portion 15 a 1) of the chassis 15 constituting the backlight device 12. Thus, the outer peripheral ends of the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19 that are optical members can be collectively held. The frame 13 includes a frame main body 23 that has a substantially channel shape (substantially portal shape) following the three sides included in the outer peripheral end of the optical member such as the liquid crystal panel 11, and the outer periphery of the optical member such as the liquid crystal panel 11. The frame main body 23 and the connection extension include a connection extension portion (connection portion) 24 extending along one side portion excluding the three side portions included in the end portion. By connecting the portions 24, a horizontally long frame shape (frame shape) surrounding the optical member such as the liquid crystal panel 11 as a whole is formed. In FIG. 7, the liquid crystal panel 11 and the optical sheet 20 are illustrated by a two-dot chain line.

  As shown in FIGS. 1 and 7, the frame main body 23 is a pair of first sides extending along a pair of short side ends that form opposite sides of the outer peripheral end of the optical member such as the liquid crystal panel 11. The other of the extended portions 25 and the other end sandwiched between the ends of the pair of short sides of the outer peripheral ends of the optical member such as the liquid crystal panel 11, etc. It is comprised from the 2nd extension part 26 extended along the edge part of the long side of the back | inner side shown in FIG.1 and FIG.7. That is, the frame main body 23 is configured to be parallel to each other by bending the pair of first extending portions 25 to the same side from both ends in the extending direction of the second extending portion 26. The pair of first extending portions 25 has an extending direction that coincides with the Y-axis direction, whereas the second extending portion 26 has an extending direction that coincides with the X-axis direction. The directions are perpendicular to each other. The pair of first extending portions 25 are substantially the same in length and shorter than the length of the second extending portion 26. In manufacturing the frame main body 23, a linear base material is formed by extruding a metal material such as aluminum, and then a pair of the main body 23 is formed with respect to the portion corresponding to the second extending portion 26. The portion corresponding to the first extending portion 25 is bent substantially at a right angle, or is subjected to bending or the like, so that it is formed into a substantially channel shape as a whole.

  As shown in FIGS. 4 and 5, the frame main body 23 is arranged on the front side with respect to the liquid crystal panel 11, and between the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the plate-like portion 15 a of the chassis 15. The liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19, and the plate-like portion 15 a of the chassis 15 between the clamping portion (optical member support portion) 23 a that collectively holds the reflection sheet 19 and the clamping portion 23 a. At least a receiving portion 23b that can receive the plate-like portion 15a from the back side (the side opposite to the optical member side such as the liquid crystal panel 11) and a side wall portion 23c that connects the frame main body 23 and the receiving portion 23b. Have. These clamping part 23a, receiving part 23b, and side wall part 23c are formed in the 1st extension part 25 and the 2nd extension part 26, respectively. In addition, as shown in FIG.1 and FIG.7, while the clamping part 23a and the side wall part 23c are continuously formed in the form ranging over each 1st extension part 25 and the 2nd extension part 26, The receiving portion 23 b is formed in a form that is divided into each first extending portion 25 and second extending portion 26. The reason why only the receiving portion 23b is divided for each of the extending portions 25 and 26 is due to the method for manufacturing the frame main body 23 described above, and the receiving portion 23b is a bent portion (corner of the frame main body 23). Part) is present inside the clamping part 23a and the side wall part 23c. That is, when manufacturing the frame main body 23, a linear base material is formed by extrusion molding, and then a notched portion is formed by performing cutting or the like on a planned bending portion of a portion corresponding to the receiving portion 23b of the base material. By forming, the receiving portion 23b is divided into three for each extending portion 25, 26, and it is allowed to subsequently bend the substrate. In addition, since the sandwiching portion 23a may be fleshed in the bent portion when the bending process is performed, the surface is smoothed by performing, for example, a diamond cutting process after the bending process. .

  As shown in FIGS. 4 and 5, the holding portion 23 a constituting the frame main body 23 is against the end portions of the three sides excluding the end portion on the connecting extension portion 24 side of the outer peripheral end portion of the liquid crystal panel 11. The liquid crystal panel 11 can be supported from the front side by being arranged oppositely on the front side and the surface on the back side being in contact with or close to the end of the three sides. The ends of the three sides of the optical member such as the liquid crystal panel 11 are collectively held between the plate-like portion 15a of the chassis 15. The receiving portion 23b is arranged on the back side so as to be opposed to the end portions of the three sides excluding the end portion on the connecting extension portion 24 side of the outer peripheral end portion of the plate-like portion 15a of the chassis 15. It is possible to receive the edge of the side from the back side. The clamping part 23a has a dimension that protrudes inward from the side wall part 23c, that is, a margin for the liquid crystal panel 11 (overlapping range with the liquid crystal panel 11) is very small. It is assumed that the dimension is smaller than the dimension protruding to the chassis 15, that is, smaller than the allowance for the chassis 15 (the overlapping range with the chassis 15). Specifically, the sandwiching portion 23a is disposed at a position where the inner end position does not reach the display area of the liquid crystal panel 11 and remains in the non-display area, or near the boundary between the display area and the non-display area. . Thereby, narrowing of the frame of the liquid crystal display device 10 is achieved. The receiving portion 23b has a sufficient allowance for the chassis 15, and more specifically, the inner end position thereof is arranged inward from the inner end position of the holding portion 23a, so that the receiving portion 23b is within the display area of the liquid crystal panel 11. It is supposed to be arranged to reach. The sandwiching portion 23a and the receiving portion 23b are arranged to face each other with a predetermined interval between them in the Z-axis direction. The intervals are the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19, and the chassis. The thickness of each of the 15 plate-like portions 15a is larger than the sum of all thickness dimensions (thickness dimensions of the laminate described later), and the difference in dimensions between the plate-like portion 15a and the receiving portion 23b described later. The interval C is almost the same as the interval C. The side wall portion 23c is arranged so as to surround the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19 and the chassis 15 from the outside, and the sandwiching portion 23a extends inward from the front end portion thereof. The receiving portions 23b are formed so as to protrude inward from the end on the back side. Further, a side plate receiving groove portion 23e for receiving a cabinet side plate portion 14b constituting the cabinet 14 described later is formed between the receiving portion 23b and the side wall portion 23c in the frame main body 23 so as to open to the back side. In addition, as shown in FIG.1 and FIG.7, the side wall part 23c and the clamping part 23a which a pair of 1st extension part 25 has are facing toward the opposite side to the 2nd extension part 26 side rather than the receiving part 23b. It is arranged in a protruding form.

  As shown in FIGS. 1 and 7, the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflective sheet 19, and the chassis 15 that are stacked on each other are extended to the frame body 23. There is an opening 23d that can be inserted between the sandwiching portion 23a and the receiving portion 23b along the existing direction (Y-axis direction). The opening 23d has a sandwiching portion 23a and a receiving portion 23b at the end of the pair of first extending portions 25 opposite to the second extending portion 26 side (the side to which the connecting extending portion 24 is connected). The space (the holding space between the optical member such as the liquid crystal panel 11 and the chassis 15) between the first extending portion 25 and the second extending portion 26 is directed to the opposite side to the second extending portion 26 side. It is formed to release. As a result, a laminated body constituted by laminating the liquid crystal panel 11, which is an optical member, the optical sheet 20, the light guide plate 18, and the reflective sheet 19 on the plate-like portion 15a of the chassis 15 is formed along the plate surface of the frame body. It is possible to assemble them all together by inserting (sliding) them into 23.

  Since the LED board 17 is assembled together with the light guide plate 18 in advance in the chassis 15 that is slidably assembled to the frame body 23 in this way, the light guide plate 18 is attached to the LED board 17 when the frame body 23 is assembled. There is a concern that the light guide plate 18 interferes with the LED 16 when the relative displacement is caused. On the other hand, as shown in FIG. 7, the chassis 15 is provided with a positioning portion 36 that positions the light guide plate 18 with respect to the LED 16 in the insertion direction with respect to the frame body 23 (the extending direction of the first extending portion 25). It has been. The positioning portions 36 are disposed at both ends of the side plate portion 15b of the chassis 15 in the extending direction (X-axis direction), and are disposed so as to sandwich the LED board 17 from both sides in the length direction. The positioning portion 36 is attached to the inner plate surface of the side plate portion 15b and protrudes inward from the plate surface. Positioning recesses 37 for receiving the positioning portions 36 described above are formed in notches at both ends in the length direction at the end portion on the long side having the light incident surface 18b of the light guide plate 18, that is, both corner portions. When the opposing surfaces of the positioning portion 36 and the positioning recess 37 abut against each other, the light guide plate 18 is positioned with respect to the side plate portion 15b and the LED substrate 17 in the Y-axis direction, whereby the Y of the light incident surface 18b and the LED 16 is determined. The positional relationship in the axial direction is kept constant. Further, the light guide plate 18 is positioned with respect to the side plate portion 15 b and the LED substrate 17 also in the X-axis direction by fitting the pair of positioning portions 36 into the pair of positioning recesses 37.

  As shown in FIGS. 1 and 7, the connecting extension 24 constituting the frame 13 together with the frame body 23 is one of the outer peripheral ends of the optical member such as the liquid crystal panel 11 (the front side shown in FIGS. 1 and 7). ) Along the end of the long side. The extension direction of the connecting extension part 24 coincides with the X-axis direction and is parallel to the extension direction of the second extension part 26 constituting the frame body 23. The length of the connecting extension 24 is substantially the same as the length of the second extension 26. In the manufacturing process, the connection extending portion 24 is formed by subjecting a base material obtained by extruding a metal material such as aluminum to a predetermined process in the same manner as the frame main body 23 described above. As shown in FIG. 4, the connection extending portion 24 is arranged on the front side with respect to the liquid crystal panel 11, and between the plate-like portion 15 a of the chassis 15, the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection. The sheet 19 is composed of a clamping part (optical member support part) 24a for clamping the sheet 19 in a lump, and a side wall part 24b protruding from the outer end part of the clamping part 24a toward the back side, and the cross-sectional shape is substantially L-shaped. I am doing.

  Specifically, as shown in FIG. 4, the sandwiching portion 24 a is an end portion of one side excluding three end portions on the frame body 23 side of the outer peripheral end portion of the liquid crystal panel 11 (an end on one long side side). The liquid crystal panel 11 can be supported from the front side by being arranged oppositely to the front side and the surface on the back side in contact with or close to the end of the same side. Thus, the end of the same side of the optical member such as the liquid crystal panel 11 is collectively held between the plate-like portion 15 a of the chassis 15. The sandwiching portion 24 a included in the connecting extension portion 24 has a surface that is flush with the surface of the sandwiching portion 23 a included in the frame main body 23, thereby avoiding a step between the two. In addition to the edge part of one side in the liquid crystal panel 11 described above, the clamping part 24a included in the connecting extension part 24 includes an edge part where the light incident surface 18b of the light guide plate 18 is disposed, the LED 16, the LED board 17, and the chassis The 15 side plate portions 15b are arranged so as to overlap in a plan view. Therefore, the clamping part 24a included in the connecting extension part 24 has a dimension that protrudes inward from the side wall part 24b, and is larger than the same dimension of the clamping part 23a included in the frame body 23. A reflective member (light-shielding member) 31 having light-shielding properties and light-reflecting properties for reflecting light is disposed on the back side of the sandwiching portion 24a of the connecting extension portion 24, that is, the space on the LED 16 side. . The reflection member 31 has an inner end in contact with the end on the LED 16 side of the liquid crystal panel 11, covers an end on the LED 16 side of the optical sheet 20 from the front side, covers the LED 16 and the LED substrate 17 from there, and covers the chassis 15. It is formed over a range up to the side plate portion 15b. Thereby, the light emitted from the LED 16 is efficiently incident on the light incident surface 18 b of the light guide plate 18 by being reflected by the reflecting member 31, and directly incident on the end surface of the liquid crystal panel 11 without passing through the light guide plate 18. The situation to do is to be avoided. The reflection member 31 extends so as to cover the outer plate surface of the side plate portion 15 b of the chassis 15. Further, a side plate receiving portion 24b2 for receiving a cabinet side plate portion 14b constituting the back cabinet 14 described below is formed on the side wall portion 24b so as to protrude inward.

  Next, the configuration of the back cabinet 14 will be described. The back cabinet 14 is formed in a substantially box shape that is open to the front as a whole, as shown in FIGS. 1, 4, and 6, by pressing the metal plate. The back cabinet 14 has a cabinet bottom plate portion 14a that is horizontally long in the same manner as the liquid crystal panel 11 in a plan view, and an outer end of each side (a pair of long sides and a pair of short sides) in the cabinet bottom plate portion 14a. It consists of the cabinet side board part 14b which stands | starts up toward the front side. The cabinet bottom plate portion 14 a is arranged in an opposing manner with a predetermined gap between the cabinet bottom plate portion 14 a and the plate-like portion 15 a of the chassis 15. The cabinet bottom plate portion 14a is arranged so as to cover almost the entire region from the back side to the receiving portion 23b of the frame 13 (including a first shaft member 27 described later) in addition to the plate-like portion 15a of the chassis 15. As a result, the chassis 15 and the receiving portion 23b are prevented from being exposed to the outside on the back side. Each cabinet side plate portion 14 b has a rising tip from the cabinet bottom plate portion 14 a inserted into the side plate receiving groove portion 23 e of the frame body 23 or abutted against the side plate receiving portion 24 b 2 of the connecting extension portion 24.

  By the way, as described above, the frame of the liquid crystal display device 10 (optical member holding structure LH) is narrowed so that the holding portion 23a of the frame body 23 constituting the frame 13 has a very small allowance for the liquid crystal panel 11. As shown in the figure, when the frame main body 23 is deformed, such as a bend, the liquid crystal panel 11 is not easily hooked, and the liquid crystal panel 11 may drop off in some cases. In addition, when an optical member such as the liquid crystal panel 11 is inserted into the frame body 23 constituting the frame 13 along the plate surface, the pair of second members constituting the frame body 23 are assembled. There is a concern that the extending portions 25 may be deformed so as to be separated from each other. When opening deformation occurs in the pair of first extending portions 25, an optical member such as the liquid crystal panel 11 cannot be sandwiched between the chassis 15 and an assembling workability may be deteriorated. Therefore, in the present embodiment, as shown in FIG. 5, the pair of first extending portions 25 is opened by engaging the pair of first extending portions 25 forming the frame body 23 and the chassis 15 with each other. Thus, a restriction structure 32 for restricting relative displacement is provided. Since the relative displacement of the pair of first extending portions 25 is restricted by the restricting structure 32 so that the pair of first extending portions 25 is opened, the amount of the holding portion 23a of the pair of first extending portions 25 with respect to the liquid crystal panel 11 is constant. As a result, it becomes difficult to cause a situation in which the liquid crystal panel 11 falls off even if the frame is narrowed and the above-mentioned margin for the liquid crystal panel 11 becomes very small. Moreover, the pair of first extending portions 25 are opened by the restricting structure 32 even when the optical member such as the liquid crystal panel 11 is inserted into the frame body 23 along the plate surface to perform assembly work. Since the relative displacement is restricted in such a manner, the pair of first extending portions 25 are less likely to be opened and deformed so as to be separated from each other, and thus the optical member such as the liquid crystal panel 11 is sandwiched between the chassis 15 and the like. It becomes difficult to cause a situation where it cannot be performed, and the assembly workability is improved.

  As shown in FIG. 5, the regulation structure 32 is viewed in plan with respect to any of the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19 that are optical members (the method of the plate surface of the optical member). (Viewed from the direction of the line) Specifically, the regulation structure 32 is arranged closer to the center (inward) of the optical member such as the liquid crystal panel 11 than the sandwiching portion 23 a of the frame body 23. The restricting structure 32 is formed on the plate-like portion 15 a of the chassis 15, and is formed on the back side, that is, the restricting convex portion 33 protruding to the opposite side to the optical member side such as the liquid crystal panel 11, and the pair of first extending portions 25. And a restriction recess 34 that receives the restriction protrusion 33. Hereinafter, specific configurations of the restriction convex portion 33 and the restriction concave portion 34 will be described in detail.

  As shown in FIGS. 5 and 8, the restricting convex portion 33 is formed in a paired manner at both end portions on the short side of the plate-like portion 15 a of the chassis 15. The restriction convex portion 33 has a plate-like shape (rail shape) extending along the short side direction of the plate-like portion 15a, that is, the insertion direction with respect to the frame main body 23, and the plate surface is parallel to the insertion direction. In addition, it is orthogonal to the plate surface of the plate-like portion 15a. That is, the restricting convex portion 33 has its plate surface parallel to the Y-axis direction and the Z-axis direction, the extending direction is the Y-axis direction, and the width direction (the protruding direction from the plate-like portion 15a) is the Z-axis direction. And the plate | board thickness direction corresponds with the X-axis direction, respectively. The restricting convex portion 33 is formed over most of the light guide plate support portion 15a1 (substantially the entire region excluding the end portion on the substrate housing portion 15a2 side) of the plate-like portion 15a, and is opposite to the substrate housing portion 15a2 side. End, that is, from the front end in the insertion direction to the frame body 23, including the central portion in the same insertion direction (extending direction of the first extension portion 25), near the substrate housing portion 15a2 (near the rear end portion in the insertion direction) ). When the chassis 15 is manufactured, the restriction convex portion 33 is formed with a slit S in the vicinity of the end portion on the substrate housing portion 15a2 side of both ends on the short side of the light guide plate support portion 15a1 of the plate-like portion 15a. It is formed by bending the front side portion in the insertion direction toward the back side. The pair of restricting convex portions 33 includes an inner plate facing each other, that is, a plate surface (inner facing surface) 33a facing the center side of the optical member, and an outer plate surface (outer facing surface) facing opposite to each other. ) 33b, of which the inner plate surface 33a is in contact with the inner facing surface 34a of the regulating recess 34 described below, thereby restricting the opening of the pair of first extending portions 25. Is possible.

  As shown in FIGS. 5 and 7, the restriction recesses 34 are respectively formed in a pair with the pair of first extending portions 25 of the frame body 23. The restricting recesses 34 extend along the extending direction (Y-axis direction) of each first extending portion 25, that is, the insertion direction of a laminated body such as an optical member with respect to the frame body 23 and the extending direction of the restricting convex portion 33. It has a groove shape. The restriction recess 34 has an extending direction that coincides with the Y-axis direction, a depth direction that coincides with the Z-axis direction, and a groove width direction that coincides with the X-axis direction. The regulating recess 34 is formed over the entire length of each first extending portion 25. Therefore, the regulating recess 34 is inserted in the direction in which the laminated body such as the optical member is inserted from the end of the first extending portion 25 on the opening 23d side (the front side in the insertion direction) that receives the laminated body such as the optical member. It can be said that it extends to the end on the side opposite to the opening 23d side (the back side in the insertion direction) including the central portion in the extending direction of the first extending portion 25). As a result, even in the initial stage of assembling the laminated body formed by laminating the optical member such as the liquid crystal panel 11 on the chassis 15 so as to be inserted into the frame main body 23, the regulating convex portion 33 is fitted in the regulating concave portion 34. As a result, in addition to the opening of the pair of first extending portions 25 being restricted, even when the assembly is completed, the opening of the pair of first extending portions 25 is restricted over the entire length. In the first extending portion 25, the center portion in the extending direction in which the opening is most likely to occur is effectively restricted by the restricting convex portion 33 and the restricting concave portion 34 that are engaged with each other. The regulating recess 34 is a surface on the front side of the receiving portion 23b that is opposed to the back side of the plate-like portion 15a of the chassis 15, that is, the side from which the regulating projection 33 protrudes, in each first extending portion 25. It is formed by denting. The restriction recess 34 is arranged on the inner side of the first extending portion 25 with respect to the sandwiching portion 23a and the side plate receiving groove portion 23e in a plan view.

  As shown in FIG. 5, the regulation recess 34 has a groove width that is relatively larger than the plate thickness of the regulation projection 33. And while the opposing surface 34a inside the regulation convex part 33 in the regulation concave part 34 is in contact with the plate surface 33a inside the regulation convex part 33, the outside opposing surface in the regulation concave part 34 with respect to the regulation convex part 33 34 b is arranged so as to be separated from the plate surface 33 b so as to have a predetermined clearance with the plate surface 33 b on the outside of the restricting convex portion 33. Therefore, in a state in which the pair of restricting convex portions 33 are fitted in the pair of restricting concave portions 34, the pair of first extending portions 25 are hardly opened away from each other. On the other hand, in the process in which the pair of restricting convex portions 33 are fitted into the pair of restricting concave portions 34, the outer plate surface 33b and the outer facing surface 34b are hardly in contact with each other, so that the frictional resistance accompanying the progress of the fitting. As a result, the assembly workability is improved. Further, the distance from one inner facing surface 34 a to the other inner facing surface 34 a in the pair of regulating concave portions 34 is such that the distance from one inner plate surface 33 a to the other inner plate surface 33 a in the pair of regulating convex portions 33. Is approximately equal to the distance to In addition, since this control recessed part 34 is each formed in the 1st extension part 25 of the frame main body 23 manufactured by extrusion molding, it is similarly formed in the 2nd extension part 26 (FIG. 4). reference).

  As shown in FIG. 7 and FIG. 9, the introduction of the restriction convex portion 33 is guided to the end portion on the opening 23 d side of the restriction concave portion 34, that is, the end portion on the side where the counterpart restriction convex portion 33 is introduced. A guide surface 35 is formed. The guide surface 35 is formed by cutting out the inner groove edge at the end of the restricting recess 34 on the opening 23d side, and the groove width of the restricting recess 34 is the opening end side, that is, the insertion direction of the restricting protrusion 33. The taper is formed so as to be wider toward the front side and to be narrower toward the back side in the insertion direction of the restricting convex portion 33. As a result, when the restriction convex portion 33 is inserted into the restriction concave portion 34, the front end portion in the insertion direction of the restriction convex portion 33 is brought into sliding contact with the guide surface 35, so that the restriction convex portion 33 becomes the restriction concave portion 34. The chassis 15 is smoothly introduced, and thereby the assembling workability of the chassis 15 becomes better.

  As described above, in the optical member holding structure LH according to the present embodiment, as shown in FIGS. 1 and 7, the optical member such as the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19 and the chassis 15. Are laminated together into openings 23d in the frame main body 23 constituting the frame 13, so that the optical system is interposed between the holding portions 23a, 24a of the frame 13 and the plate-like portion 15a of the chassis 15. Since the outer peripheral end portion of the member is clamped, the conventionally used slide mounting bracket is not required, and the frame is narrowed by the space for arranging the slide mounting bracket. In addition, as shown in FIGS. 4 and 5, the receiving portion 23 b that forms the frame body 23 is formed by removing the end portion on the connecting extension portion 24 side from the outer peripheral end portion of the plate-like portion 15 a of the chassis 15. Since it is arranged oppositely on the back side with a predetermined distance (clearance) C with respect to the end of the side, a laminated body in which the optical member such as the liquid crystal panel 11 and the chassis 15 are laminated as described above. When the work is inserted into the opening 23d of the frame main body 23, it becomes easier to insert the laminate between the receiving portion 23b and the clamping portion 23a of the frame main body 23, thereby improving the workability related to the insertion work. It becomes. A first shaft member (spacer portion) 27 is disposed between the cabinet bottom plate portion 14a of the back cabinet 14 and the plate-like portion 15a of the chassis 15. Since the plate-like portion 15a is supported by the cabinet bottom plate portion 14a, the gap C between the receiving portion 23b of the frame body 23 and the plate-like portion 15a is maintained, so that the plate-like portion 15a An optical member such as the liquid crystal panel 11 that is sandwiched between the sandwiching portion 23a is less likely to be rattled. As described above, in addition to being able to achieve a narrow frame, it is possible to achieve both improvement in workability related to the insertion work of the laminate and suppression of rattling of the optical member. Next, the first shaft member 27 described above will be described together with the structure for attaching the frame 13 and the back cabinet 14 to the chassis 15.

  The first shaft member 27 is made of metal like the chassis 15 and the like, and as shown in FIGS. 4 and 5, the first shaft member 27 is caulked to the light guide plate support portion 15 a 1 in the plate-like portion 15 a, thereby the chassis. 15 is provided integrally. That is, the first shaft member 27 is manufactured as a separate component from the chassis 15 and is integrated with the chassis 15 by assembly. A first shaft attachment hole (spacer attachment portion) 38 to which the first shaft member 27 is attached so as to penetrate therethrough is formed in the light guide plate support portion 15a1 of the plate-like portion 15a. The first shaft member 27 has a dimension (height dimension) in the direction orthogonal to the plate surfaces of the light guide plate support 15a1 and the cabinet bottom plate 14a of the back cabinet 14 in the plate-like portion 15a of the chassis 15, that is, the Z-axis direction. The size of the receiving portion 23b is relatively larger than the same size, and the difference in size is substantially equal to the distance C between the receiving portion 23b and the light guide plate support portion 15a1 of the plate-like portion 15a. ing. Accordingly, the light guide plate support portion 15a1 and the cabinet bottom plate portion 14a of the plate-like portion 15a are substantially flat along the X-axis direction and the Y-axis direction, and the shapes of the chassis 15 and the back cabinet 14 are simplified. In addition, it is possible to keep the gap C between the receiving portion 23b and the light guide plate support portion 15a1 favorably. Further, the surfaces facing the back side of the first shaft member 27 and the receiving portion 23b (facing surfaces facing the cabinet bottom plate portion 14a) are substantially flush with each other. The first shaft member 27 and the first shaft mounting hole 38 are disposed at a position that is not overlapped with the receiving portion 23b in a plan view, and are disposed closer to the center of the plate-like portion 15a than the receiving portion 23b. Yes. Here, the plate-like portion 15a tends to be easily deformed such as bending at the center side rather than the end side, whereas the plate-like portion is more plate-like than the receiving portion 23b as described above. By arrange | positioning in the center side in 15a, the center side of the plate-shaped part 15a is supported by the cabinet bottom board part 14a via the 1st shaft member 27. FIG. As a result, the plate-like portion 15a and the optical member such as the liquid crystal panel 11 stacked on the plate-like portion 15a are unlikely to be deformed.

  As shown in FIG. 8, a plurality of first shaft members 27 and first shaft attachment holes 38 are distributed in the plane of the plate-like portion 15a. Specifically, a total of nine first shaft members 27 and first shaft mounting holes 38 are intermittently arranged along the circumferential direction in the outer peripheral portion of the plate-like portion 15a. Thus, a total of five pieces are intermittently arranged in the central portion of the plate-like portion 15a. The first shaft member 27 and the first shaft mounting hole 38 arranged on the outer peripheral side portion of the plate-like portion 15 a are along the extending directions of the extending portions 25 and 26 of the frame body 23 and the connecting extending portion 24. And are arranged at positions adjacent to the center side of the plate-like portion 15a with respect to the extending portions 25 and 26 and the connecting extending portion 24. More specifically, the first shaft member 27 and the first shaft attachment hole 38 disposed on the outer peripheral side portion of the plate-like portion 15a are positioned adjacent to the first extending portions 25 of the frame body 23 and the first Two ones arranged intermittently along the extending direction (Y-axis direction) of the one extending part 25 and a position adjacent to the second extending part 26 and the second extending part 26 Three each arranged intermittently along the extending direction (X-axis direction), and the extending direction of the connecting extending part 24 (X-axis) at a position adjacent to the connecting extending part 24 And two each arranged intermittently along the (direction).

It is possible to tighten a screw member for attaching a metal fitting for wall or a wall (both not shown).

  As shown in FIG. 6, the back cabinet 14 can be fixed to the receiving portion 23 b arranged with a gap C between the first shaft member 27 and the plate-like portion 15 a of the chassis 15 as described above. A possible receiving part fixing member 39 is attached. Since the back cabinet 14 is fixed to the receiving portion 23b by the receiving portion fixing member 39, the positional relationship in the Z-axis direction of the cabinet bottom plate portion 14a with respect to the receiving portion 23b is stably maintained. The positional relationship in the Z-axis direction of the first shaft member 27 and the plate-like portion 15a indirectly with respect to the portion 23b is also stabilized, so that the interval C between the plate-like portion 15a and the receiving portion 23b is stable. It is designed to be retained. The receiving portion fixing member 39 is a so-called screw member, and the axial direction thereof coincides with the Z-axis direction (the direction orthogonal to the plate surfaces of the light guide plate support portion 15a1 and the cabinet bottom plate portion 14a) and the outer peripheral surface has a thread. It consists of a threaded shaft portion and a hook-shaped head portion provided on one end side of the shaft portion. On the other hand, the receiving portion 23b is provided with a receiving portion-side fixing portion 23b1 to which the receiving portion fixing member 39 is fastened. The receiving portion side fixing portion 23b1 has a hole shape penetrating the receiving portion 23b along the Z-axis direction, and a thread groove that is screwed into the thread of the receiving portion fixing member 39 is formed on the inner peripheral surface thereof. ing. Further, in the cabinet bottom plate portion 14a, a receiving portion fixing member insertion hole 14a2 through which the receiving portion fixing member 39 is inserted is fixed to each receiving portion side fixing portion at a position overlapping the receiving portion side fixing portions 23b1 in plan view. The openings are formed so as to communicate with the portion 23b1.

  The receiving portion fixing member 39, the receiving portion side fixing portion 23b1, and the receiving portion fixing member insertion hole 14a2 are in a plane with the receiving portion 23b of the frame main body 23, as shown in FIGS. Since it is arranged at a position where it overlaps when viewed, it is arranged on the end side in the plate-like portion 15 a rather than the first shaft member 27. Since the frame body 23 is configured such that the receiving portion 23b and the sandwiching portion 23a are connected by the side wall portion 23c, the receiving portion fixing member 39 and the like are more plate-like portions 15a than the first shaft member 27 as described above. The width of the receiving portion 23b and the frame main body 23 can be kept small.

  The receiving portion fixing member 39, the receiving portion side fixing portion 23b1, and the receiving portion fixing member insertion hole 14a2 are intermittently provided at a plurality of locations in the extending direction of the receiving portion 23b, as shown in FIGS. They are arranged in a line. Specifically, the receiving portion fixing member 39, the receiving portion side fixing portion 23b1, and the receiving portion fixing member insertion hole 14a2 are in the Y-axis direction, which is the extending direction of the receiving portion 23b of each first extending portion 25. Are arranged side by side intermittently along the X direction, whereas the receiving portion 23b of the second extending portion 26 is intermittently arranged side by side along the X axis direction that is the extending direction. It is arranged with. The receiving portion fixing member 39, the receiving portion side fixing portion 23b1, and the receiving portion fixing member insertion hole 14a2 are adjacent to the extending portions 25 and 26 forming the frame main body 23 in the first shaft member 27 and the extending portions thereof. Those arranged side by side along the direction are arranged so as to be sandwiched between the extending directions of the extending portions 25 and 26. Specifically, the three receiving portion fixing members 39, the receiving portion side fixing portions 23b1, and the receiving portion fixing member insertion holes 14a2 arranged along the extending direction (Y-axis direction) of each first extending portion 25 are provided as follows. The two first shaft members 27 adjacent to each first extending portion 25 are arranged so as to be sandwiched in the Y-axis direction. In other words, each of the three receiving portion fixing members 39, the receiving portion side fixing portions 23b1, and the receiving portion fixing member insertion holes 14a2 arranged along the extending direction of each first extending portion 25 has a first fixing portion. The plate-like portion 15a is sandwiched between the two first shaft members 27 adjacent to the extending portion 25 in the Y-axis direction and the two first shaft members 27 in the Y-axis direction. And those arranged on both ends. On the other hand, the four receiving portion fixing members 39, the receiving portion side fixing portions 23b1, and the receiving portion fixing member insertion holes 14a2 arranged along the extending direction of the second extending portion 26 (X-axis direction) 2 The first shaft member 27 adjacent to the extending portion 26 is arranged so as to be sandwiched in the X-axis direction. In other words, each of the four receiving portion fixing members 39, the receiving portion side fixing portion 23b1, and the receiving portion fixing member insertion hole 14a2 arranged along the extending direction of the second extending portion 26 has a second extension. A plate-like portion in the X-axis direction with respect to those sandwiched between the three first shaft members 27 adjacent to the portion 26 in the X-axis direction and those located at both ends of the three first shaft members 27 And those arranged on both ends of 15a. Therefore, the receiving portion fixing member 39 and the first shaft member 27 that are arranged side by side along the extending portions 25 and 26 of the frame body 23 are arranged side by side in a zigzag shape (staggered shape) when viewed in plan. ing.

  Furthermore, as shown in FIGS. 4 and 5, the back cabinet 14 can be fixed to all of the first shaft members 27 except for the stationary stand and the wall mounting bracket. A first shaft member fixing member (spacer fixing member) 28 is attached. When the back cabinet 14 is fixed to the first shaft member 27 by the first shaft member fixing member 28, a portion of the cabinet bottom plate portion 14a that overlaps the first shaft member 27 in a plan view is first. By being sandwiched between the shaft member 27 and the first shaft member fixing member 28, it is difficult for deformation such as bending to occur in the overlapping portion. As a result, in the cabinet bottom plate portion 14a, the portion overlapping the first shaft member 27 and the portion overlapping the receiving portion 23b are orthogonal to the Z-axis direction (light guide plate support portion 15a1 and the plate surface of the cabinet bottom plate portion 14a). The plate-like portion 15a is better supported by the cabinet bottom plate portion 14a via the first shaft member 27, so that there is a gap between the plate-like portion 15a and the receiving portion 23b. The interval C is maintained more stably. The first shaft member fixing member 28 is a so-called screw member, and is provided on a shaft portion whose axial direction coincides with the Z-axis direction and whose outer peripheral surface is threaded, and on one end side of the shaft portion. It consists of a bowl-shaped head. On the other hand, the first shaft member 27 is provided with a first shaft member side fixing portion (spacer side fixing portion) 27a to which the first shaft member fixing member 28 is fastened. The first shaft member-side fixing portion 27a has a hole shape penetrating the first shaft member 27 along the Z-axis direction and is screwed into the inner peripheral surface of the first shaft member fixing member 28 with the thread of the first shaft member fixing member 28. A groove is threaded. That is, the 1st shaft member 27 has comprised the substantially cylindrical shape by which the 1st shaft member side fixing | fixed part 27a was penetrated and formed in the center. Further, in the cabinet bottom plate portion 14a, the first shaft member fixing member insertion hole 14a1 through which the first shaft member fixing member 28 is inserted at a position overlapping the first shaft member side fixing portions 27a in plan view. Are formed so as to communicate with the first shaft member side fixing portions 27a.

  As shown in FIGS. 4 to 6, the frame body 23 of the frame 13 is described above in a state where the optical member such as the liquid crystal panel 11 and the chassis 15 are sandwiched between the sandwiching portion 23 a and the receiving portion 23 b. While the back cabinet 14 is fixed by the first shaft member fixing member 28 and the receiving portion fixing member 39, the connecting extension portion 24 has a second shaft member 29 described below as shown in FIG. The second shaft member fixing member 30 is fixed to the chassis 15. A plurality of second shaft members 29 and second shaft member fixing members 30 are intermittently arranged along the extending direction (X-axis direction) of the connection extending portion 24 and the side plate portion 15b. Among these, the second shaft member 29 is disposed so as to be interposed between the connecting extension portion 24 and the side plate portion 15 b and is caulked to the side plate portion 15 b of the chassis 15, thereby being integrated with the chassis 15. Is provided. That is, the second shaft member 29 is manufactured as a separate component from the chassis 15 similarly to the first shaft member 27 and is integrated with the chassis 15 by assembly. The side plate portion 15b is formed with a second shaft attachment hole 40 through which the second shaft member 29 is attached in a penetrating manner. The second shaft member fixing member 30 is a so-called screw member. The second shaft member fixing member 30 is provided on a shaft portion in which the axial direction coincides with the Y-axis direction and a thread is formed on the outer peripheral surface thereof, and on one end side of the shaft portion. It consists of a bowl-shaped head. On the other hand, the second shaft member 29 is provided with a second shaft member side fixing portion 29a to which the second shaft member fixing member 30 is fastened. The second shaft member side fixing portion 29a has a hole shape penetrating the second shaft member 29 along the Y-axis direction and is screwed into the inner peripheral surface of the second shaft member fixing portion 29a with the thread of the second shaft member fixing member 30. A groove is threaded. That is, the 2nd shaft member 29 has comprised the substantially cylindrical shape by which the 2nd shaft member side fixing | fixed part 29a was penetrated and formed in the center. Further, the side wall portion 24b that forms the connecting extension portion 24 is disposed on the outer side so as to be opposed to the side plate portion 15b of the chassis 15 with the second shaft member 29 interposed therebetween. A second shaft member insertion hole 24b1 through which the two shaft member fixing member 30 passes is formed. The second shaft member fixing member 30 is screwed into the second shaft member side fixing portion 29a of the second shaft member 29 through the second shaft member insertion hole 24b1, thereby connecting the connecting extension portion 24 to the chassis 15.

  The liquid crystal display device 10 according to the present embodiment has the above-described structure, and then an assembly method thereof will be described. When the liquid crystal display device 10 is assembled, first, the LED substrate 17 and the positioning portion 36 are attached to the side plate portion 15b of the chassis 15, and the shaft members 27 and 29 are respectively crimped to the plate-like portion 15a and the side plate portion 15b. Subsequently, the reflection sheet 19, the light guide plate 18 and the optical sheet 20 are sequentially stacked on the plate-like portion 15 a of the chassis 15, and further, as shown in FIGS. 7 and 9, a liquid crystal panel is formed on the optical sheet 20. 11 are stacked. And the laminated body (lamination | stacking unit) which consists of the chassis 15, the reflection sheet 19, the light-guide plate 18, the optical sheet 20, and the liquid crystal panel 11 was formed between the edge parts of a pair of 1st extension part 25 in the frame main body 23. It is made to insert at a time between the clamping part 23a and the receiving part 23b through the opening part 23d. Here, since the space | interval which has between the clamping part 23a which comprises the frame main body 23, and the receiving part 23b is made larger than the thickness dimension of an above-described laminated body, the clamping part 23a and the receiving part 23b The laminate can be inserted with a sufficient margin between the two and the insertion work can be performed smoothly, and the liquid crystal panel 11 is less likely to interfere with the clamping portion 23a, so that the liquid crystal panel 11 is hardly damaged. .

  Along with the insertion of the laminated body, a pair of restricting convex portions 33 provided on the bottom plate portion 15a of the chassis 15 are provided on each first extending portion 25 of the frame main body 23 as shown in FIGS. The pair of restriction recesses 34 are inserted. As described above, in the initial stage of the stacking operation of the laminated body, the relative displacement of the pair of first extending portions 25 is restricted by the restriction structure 32, so that the assembly workability is improved. The optical member such as the liquid crystal panel 11 can be firmly clamped between the chassis 15 by the sandwiching portion 23a, and it is difficult for the optical member such as the liquid crystal panel 11 to drop off during the assembly operation. At this time, the restriction convex portion 33 introduced into the restriction concave portion 34 is guided smoothly by introduction of the front end portion in the insertion direction in sliding contact with the guide surface 35 formed in the restriction concave portion 34. Workability related to insertion is good. Moreover, the light guide plate 18 is restricted from being displaced so as to approach the LED 16 when the positioning portion 36 on the chassis 15 side is brought into contact with the positioning recess 37 formed in the corner portion on the LED 16 side. Even when an impact or vibration occurs when the above-described laminate is inserted, a situation where the light incident surface 18b interferes with the LED 16 is unlikely to occur. This avoids a situation where the light incident surface 18b and the LED 16 are damaged. In addition, in FIG. 10, illustration of LED board 17, the reflection member 31, the positioning part 36, etc. is abbreviate | omitted.

  When the above-described laminated body is inserted to the back end position of the frame main body 23, the three side ends of the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19 are sandwiched by the sandwiching portion 23 a of the frame main body 23 and the chassis 15. And the plate-like portion 15a. In other words, the end portions of the three sides of the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19, and the chassis 15 are sandwiched and held between the sandwiching portion 23a and the receiving portion 23b of the frame body 23. . Here, as described above, the interval between the holding portion 23a and the receiving portion 23b forming the frame main body 23 is larger than the thickness dimension of the laminated body described above. For this reason, when performing the above-described insertion operation (slide operation), for example, the X-axis direction and the Y-axis direction are made to coincide with the horizontal direction, the Z-axis direction is made to coincide with the vertical direction, and the receiving portion 23b of the frame body 23 is made vertical. When the sandwiching portion 23a is arranged on the lower side in the direction and on the upper side in the vertical direction, as shown in FIGS. 12 and 13, the chassis 15, the reflection sheet 19, and the light guide plate 18 are placed on the receiving portion 23b. In addition, the optical sheet 20 and the liquid crystal panel 11 are placed in a stacked state, and a space C1 is provided between the outer peripheral end of the liquid crystal panel 11 disposed on the uppermost stage and the sandwiching portion 23a. . In this state, the first shaft member 27 has a lower side in the vertical direction such that the surface facing the lower side (back side) in the vertical direction has a step with respect to the surface facing the lower side in the vertical direction in the receiving portion 23b. The protruding margin is substantially the same as the interval C1 provided between the outer peripheral end of the liquid crystal panel 11 and the sandwiching portion 23a.

  Subsequently, an operation of connecting the connection extending portion 24 to the frame main body 23 is performed. The opening 23d of the frame body 23 is closed by fitting the connecting extension 24 between the ends on the opening 23d side of the pair of first extending portions 25 forming the frame body 23. The connecting extension portion 24 has the second shaft member fixing member 30 passed through the second shaft member insertion hole 24b1 and the second shaft member fixing member 30 is connected to the second shaft member 29 on the chassis 15 side. The second shaft member side fixing portion 29a is screwed to be fixed to the chassis 15 (see FIG. 4). As a result, the laminated body including the chassis 15, the reflection sheet 19, the light guide plate 18, the optical sheet 20, and the liquid crystal panel 11 is kept from being detached from the frame body 23. In addition, since the frame 13 having a frame shape as a whole is configured by assembling the connecting extension portion 24 to the frame main body 23, the outer peripheral end portions of the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19. Is sandwiched between the sandwiching portions 23 a and 24 a of the frame 13 and the plate-like portion 15 a of the chassis 15.

  When the assembling work of the frame 13 is thus completed, the assembling work of the back cabinet 14 is performed next. When performing the assembling work of the back cabinet 14, for example, the frame 13 and the laminated body are reversed from the posture shown in FIGS. 12 and 13, and the receiving portion of the frame main body 23 as shown in FIGS. 23b is arranged on the upper side in the vertical direction, and the clamping part 23a is arranged on the lower side in the vertical direction. In this state, the liquid crystal panel 11, the optical sheet 20, the reflection sheet 19, the light guide plate 18, and the chassis 15 are stacked on the sandwiching portion 23 a, and the plate shape of the chassis 15 disposed on the uppermost stage is placed. A space C is provided between the outer end of the portion 15a and the receiving portion 23b. The interval C is substantially the same as the above-described interval C1 (see FIGS. 12 and 13). In this state, the surface of the first shaft member 27 facing the upper side (back side) in the vertical direction is substantially flush with the surface of the receiving portion 23b facing the upper side in the vertical direction. On the other hand, the back cabinet 14 is assembled from the upper side (back side) in the vertical direction with respect to the frame 13 and the chassis 15 in a posture in which each cabinet side plate portion 14b faces the lower side (front side) in the vertical direction. As the cabinet 14 is assembled, the cabinet bottom plate portion 14a is brought into contact with the vertically downward surface of the first shaft member 27 and the receiving portion 23b. . At this time, each cabinet side plate portion 14b is received by the side plate receiving groove portion 23e of the frame body 23 and the side plate receiving portion 24b2 of the connection extending portion 24, so that the cabinet 14 in the X axis direction, the Y axis direction, and the Z axis direction. Is positioned.

  In this state, the receiving portion fixing member 39 is passed through the receiving portion fixing member insertion hole 14a2 formed in the cabinet bottom plate portion 14a of the cabinet 14, and the receiving portion side fixing formed in the receiving portion 23b forming the frame body 23 is performed. By fastening to the portion 23b1, the back cabinet 14 is fixed to the receiving portion 23b, that is, the frame main body 23 (frame 13) (see FIG. 6). At this time, the first shaft member 27 is interposed between the cabinet bottom plate portion 14a of the back cabinet 14 fixed to the receiving portion 23b and the plate-like portion 15a of the chassis 15, so that the plate-like portion 15a and the cabinet bottom plate are disposed. The space between the first and second portions 14a is maintained at the height of the first shaft member 27 (dimension in the Z-axis direction). Thereby, the space | interval C opened between the receiving part 23b and the plate-shaped part 15a is maintained as it is. In this state, the sandwiching portion 23a abuts on the liquid crystal panel 11 and the plate-like portion 15a abuts on the reflection sheet 19, and the liquid crystal panel 11, the optical sheet 20, the light guide plate 18 and the reflection sheet 19 stacked on each other are sandwiched. It is clamped between the portion 23a and the plate-like portion 15a with almost no gap. Thereby, generation | occurrence | production of the situation where the liquid crystal panel 11, the optical sheet 20, the light-guide plate 18, and the reflective sheet 19 rattle between the clamping part 23a and the plate-shaped part 15a is suppressed suitably. Similarly to the receiving portion fixing member 39 described above, the first shaft member fixing member 28 is passed through the first shaft member fixing member insertion hole 14a1 formed in the cabinet bottom plate portion 14a of the cabinet 14, and the first shaft member. The back cabinet 14 is fixed to the chassis 15 via the first shaft member 27 by fastening to the first shaft member side fixing portion 27a of 27 (see FIGS. 4 and 5). Prior to the assembly of the back cabinet 14, it is preferable to attach substrates such as the tuner substrate T to the plate-like portion 15 a of the chassis 15. Thus, the assembly of the television receiver TV and the liquid crystal display device 10 is completed.

Can be planned.

  In addition, the receiving portion 23b of the frame main body 23 is spaced from the plate-like portion 15a of the chassis 15 on the side opposite to the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflecting sheet 19 side which are optical members. Since the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19, and the chassis 15, which are optical members, are inserted into the opening 23 d of the frame body 23, they are arranged so as to face each other. The liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19, and the chassis 15, which are optical members, can easily enter between the receiving portion 23 b and the sandwiching portion 23 a of the frame body 23, and thereby work related to insertion work. The property is good. In addition, the back cabinet 14 is attached so as to be arranged on the opposite side of the chassis 15 to the plate-like portion 15a side with respect to the receiving portion 23b, and interposed between the back cabinet 14 and the plate-like portion 15a. Since the first shaft member 27 is arranged in such a manner that a gap C is maintained between the receiving portion 23b and the plate-like portion 15a, the gap between the plate-like portion 15a and the sandwiching portions 23a and 24a is maintained. The liquid crystal panel 11, the optical sheet 20, the light guide plate 18, and the reflection sheet 19, which are optical members to be sandwiched, are unlikely to be rattled.

The optical sheet 20, the light guide plate 18, and the reflection sheet 19 are less likely to rattle and can be more stably sandwiched.

  The plurality of receiving portion fixing members 39 are arranged so as to sandwich the first shaft member 27 in the extending direction of the receiving portion 23b. After the operation of inserting the liquid crystal panel 11, the optical sheet 20, the light guide plate 18, the reflection sheet 19, and the chassis 15, which are optical members, into the opening 23 d of the frame body 23, the back cabinet 14 is operated by the plurality of receiving portion fixing members 39. When fixed to the receiving portion 23b, the plate-like portion 15a is supported by the back cabinet 14 via the first shaft member 27, whereby a gap C is provided between the plate-like portion 15a and the receiving portion 23b. It is kept in the state. Since the plurality of receiving portion fixing members 39 are arranged so as to sandwich the first shaft member 27 in the extending direction of the receiving portion 23 b, the plate-like portion 15 a is more reinforced by the back cabinet 14 via the first shaft member 27. The distance C which is supported favorably and thus is provided between the plate-like portion 15a and the receiving portion 23b can be maintained more stably.

  The first shaft member 27 is provided on the plate-like portion 15 a and includes a first shaft member fixing member (spacer fixing member) 28 that fixes the back cabinet 14 to the first shaft member 27. After performing the operation | work which inserts the liquid crystal panel 11, the optical sheet 20, the light-guide plate 18, the reflection sheet 19, and the chassis 15 which are optical members into the opening part 23d of the frame main body 23, the plate-shaped part of the chassis 15 with respect to the receiver 23b When the back cabinet 14 is attached so as to be arranged on the side opposite to the 15a side, the plate-like portion 15a is supported by the back cabinet 14 via the first shaft member 27, so that the plate-like portion 15a and the receiving portion 23b are The interval C is kept in the interval. Since the back cabinet 14 is fixed to the first shaft member 27 provided on the plate-like portion 15 a by the first shaft member fixing member 28, the back cabinet 14 is bent to a portion overlapping the first shaft member 27. Deformation such as is difficult to occur. As a result, the plate-like portion 15a is better supported by the back cabinet 14 via the first shaft member 27, and the space C between the plate-like portion 15a and the receiving portion 23b is kept more stable. Can do.

  Further, the first shaft member 27 is arranged on the center side of the plate-like portion 15a with respect to the receiving portion 23b. After performing the operation | work which inserts the liquid crystal panel 11, the optical sheet 20, the light-guide plate 18, the reflection sheet 19, and the chassis 15 which are optical members into the opening part 23d of the frame main body 23, the plate-shaped part of the chassis 15 with respect to the receiver 23b When the back cabinet 14 is attached so as to be arranged on the side opposite to the 15a side, the plate-like portion 15a is supported by the back cabinet 14 via the first shaft member 27, so that the plate-like portion 15a and the receiving portion 23b are The interval C is kept in the interval.
