  The liquid crystal display device 10 includes a liquid crystal panel 20 which is a display panel, and a backlight device 30 which irradiates the liquid crystal panel 20 with light, and these are integrally held by a frame-shaped bezel 40 or the like. Has become. The bezel 40 extends along the peripheral edge on the front side of the liquid crystal panel 20, and forms an appearance on the front side of the liquid crystal display device 10. The bezel 40 is made of metal or resin having excellent rigidity.

  The liquid crystal panel 20 is assembled such that a display surface capable of displaying an image faces a front side. The liquid crystal panel 20 has a horizontally long rectangular shape as a whole. The liquid crystal panel 20 has a configuration in which a pair of transparent glass substrates are bonded together with a predetermined gap therebetween, and a liquid crystal layer (not shown) is sealed between the two glass substrates. On one glass substrate, a switching element (for example, a TFT) connected to a source wiring and a gate wiring which are orthogonal to each other, a pixel electrode connected to the switching element, an alignment film, and the like are provided. The other glass substrate is provided with a color filter or a counter electrode in which colored portions such as R (red), G (green), and B (blue) are arranged in a predetermined arrangement, and further, an alignment film and the like. I have. Note that a polarizing plate (not shown) is provided outside the two glass substrates.

  As shown in FIG. 2, a source substrate 45 (an example of a circuit substrate) for supplying a control signal or the like to a source line formed on a glass substrate of the liquid crystal panel 20 is provided on an outer peripheral portion of the liquid crystal panel 20. It is connected via an FPC (Flexible Printed Circuits) 47. In the present embodiment, the source substrate 45 has a horizontally long rectangular shape, and a total of four substrates are arranged along one long side of the liquid crystal panel 20. The flexible substrate 47 is a thin film having flexibility, and is a substrate in which a circuit pattern is formed on a base material in which a conductor such as a copper foil is bonded to a polyimide film, for example, and six sheets are formed on each source substrate 45. Are arranged at equal intervals. The flexible substrate 47 has one end connected to the periphery of the liquid crystal panel 20 and the other end connected to the source substrate 45. The flexible substrate 47 bends and bends, so that the source substrate 45 can be disposed on the back side of the backlight device 30 as shown in FIGS. By arranging the source substrate 45 on the back side of the backlight device 30 in this manner, the width of the bezel 40 and the like can be reduced, so that the frame of the liquid crystal display device 10 can be narrowed.

  As shown in FIG. 2, the backlight device 30 includes a substantially box-shaped chassis 31 opened toward the light emitting side (the liquid crystal panel 20 side), and a diffusion plate arranged to cover the opening of the chassis 31. 60, an optical sheet 33 for giving a predetermined optical action to light emitted from the diffusion plate 60, and an outer edge of the diffusion plate 60 and an outer edge of the optical sheet 33 arranged along the outer edge of the chassis 31. And a frame 15 to be held between the chassis 31 and the frame 31. Inside the chassis 31, the LEDs 52 arranged opposite to each other at a position directly below the diffusion plate 60, the LED substrate 51 on which the LEDs 52 are mounted, and the reflection sheet 70 for reflecting the light inside the chassis 31 to the diffusion plate 60 side And are housed. As described above, the backlight device 30 according to the present embodiment is a so-called direct-type backlight device in which the LEDs 52 are arranged to face the lower side (back side) of the liquid crystal panel 20.

  The chassis 31 is made of metal, and as a whole, is formed in a shallow box shape that opens toward the front side as shown in FIG. The chassis 31 includes a bottom portion 31A having a rectangular shape similar to the liquid crystal panel 20, a side portion 31B rising from the outer end of each side of the bottom portion 31A toward the front side, and a liquid crystal panel 20 extending from the rising end of the side portion 31B. And a receiving portion 31 </ b> C extending in parallel. As shown in FIG. 3, the source substrate 45 described above is disposed on an outer surface 31S of the surface of the chassis 31 opposite to the surface on which the LEDs 52 are housed, and the source substrate 45 is connected to a wire holder 90 (holding). (An example of a member) on the outer surface 31S. Each source substrate 45 is held by one wire holder 90, and the wire holder 90 is arranged substantially at the center in the long side direction (X-axis direction) of the source substrate 45.

  If a circuit pattern is formed on the surface of the source substrate 45 on the side facing the chassis 31, the circuit pattern may come into contact with the metal chassis 31 to cause unnecessary conduction. For this reason, as shown in FIGS. 3 and 4, an insulating sheet 34 is attached to the surface of the outer surface 31 </ b> S of the chassis 31. However, in the present embodiment, since the circuit pattern of the portion serving as the reference potential is located at the center of the source substrate 45 where the wire holder 90 is arranged, as shown in FIG. In addition, the insulating sheet 34 is unnecessary at the place where the wire holder 90 is installed. By doing so, the wire holder 90 can be positioned and arranged with the gap between the insulating sheets 34 as a mark.

  The optical sheet 33 has flexibility, and has a horizontally-long rectangular shape in plan view like the liquid crystal panel 20 and the bottom plate 31A of the chassis 31. The optical sheet 33 is formed by laminating a wavelength selection sheet, a prism sheet, a reflective polarizing plate, and the like, and is disposed between the liquid crystal panel 20 and the diffusion plate 60 so that Is emitted toward the liquid crystal panel 20 while giving a predetermined optical action to the emitted light.

  The diffusion plate 60 is thicker than the optical sheet 33, and has a configuration in which a large number of diffusion particles are dispersed in a substantially transparent resin base material, for example, to diffuse transmitted light. The light emitted from the LED 52 along the Z-axis direction enters the rear plate surface (light incident surface) of the diffuser plate 60 and moves from the front plate surface (light output surface) of the diffuser plate 60 to the optical sheet 33 side. The light is emitted so as to be diffused.

  The LEDs 52 are mounted on a plate surface (mounting surface) of the plate-shaped LED substrate 51 facing the front side. As shown in FIG. 2, a plurality of LEDs 52 are arranged in parallel in a matrix at substantially equal intervals in the X-axis direction (row direction) and the Y-axis direction (column direction). As the LED 52, one that emits light (primary blue light) emitted from a blue light emitting element is used. Others that emit white light by applying a phosphor to the light emitting element, blue, red, Various types can be used, such as one in which three types of green LED chips are surface-mounted to emit white light.

  The reflection sheet 70 is a sheet-like member formed of a synthetic resin, and has a surface having a white color excellent in light reflectivity. The reflection sheet 70 is arranged on the front side (mounting surface) of the LED board 51 laid on the front side of the bottom 31A of the chassis 31 and covers the LED board 51 almost entirely.

  Next, the wire holder 90 will be described in detail with reference to FIGS. The wire holder 90 is integrally formed of nylon resin or the like, and is arranged from the side portion 31B, which is an inclined portion, to the receiving portion 31C, which is a flat portion, of the chassis 31, as shown in FIG. Also, in FIG. 5, the flexible substrate 47 is bent and bent as shown by a solid line in a state before the wire holder 90 is attached and by a two-dot chain line in the state after the attachment (the state shown in FIG. 4). Accordingly, the source substrate 45 is arranged on the outer surface 31S of the chassis 31, and the source substrate 45 is held by the wire holder 90 so that the arrangement is maintained.

  As shown in FIGS. 4 and 6, the wire holder 90 includes a fixing portion 91 fixed to the outer surface 31S of the chassis 31, a body portion 93 connected to the fixing portion 91 and extending along the outer surface 31S, 93 has a contact portion 95 provided on the opposite side to the fixed portion 91 and in contact with the outer surface 31S. The source substrate 45 is accommodated in an accommodation space S1 formed between the outer surface 31S and the main body 93.

  The fixing portion 91 has a plate shape as shown in FIGS. 4 and 6, and one plate surface 91A is adhered to the outer surface 31S of the chassis 31 by a double-sided tape 92 (an example of an adhesive member). As shown in FIG. 6, the fixing portion 91 is disposed on the side portion 31B of the chassis 31, and the fixing portion 91 and the main body portion 93 extend from the vicinity of the center of the fixing portion 91 to the direction intersecting the plate surface 91A (the plate surface 91A). (In the vertical direction of 91A).

  The main body 93 has an elongated plate shape as shown in FIGS. 4 and 6, and is vertically connected to the projection 94 so as to be parallel to the plate surface 91A of the fixing portion 91. Due to such an elongated shape of the main body 93, the main body 93 can easily move in a direction intersecting with the outer surface 31 </ b> S of the chassis 31 with the end portion (connection portion to the protrusion 94) 93 </ b> A on the fixing portion 91 side as a fulcrum. Displacement (slight rotation) is possible (FIG. 7). The length of the main body 93 from the connecting portion 93A to the protrusion 94 to the contact portion 95 is appropriately designed according to the size of the source substrate 45 so that the source substrate 45 can be accommodated.

  As shown in FIG. 6, the contact portion 95 is located near the end 93 </ b> B of the main body 93 opposite to the fixing portion 91 and at a position close to the fixing portion 91 by a predetermined distance L from the end 93 </ b> B. Is formed. The contact portion 95 is located on the chassis 31 side (the side on which the fixed portion 91 is provided) in a direction (vertical direction) crossing the plate surface of the main body portion 93 from a base end portion 95A which is a connection portion with the main body portion 93. ). In the present embodiment, the contact portion 95 is in contact with the receiving portion 31C of the chassis 31.

  Subsequently, the operation and effect of the wire holder 90 according to the above-described embodiment will be described with reference to FIGS. As described above, the main body portion 93 is slightly rotatable about the connection portion 93A with the projection 94, and separates the end portion 93B of the main body portion 93 from the chassis 31, as shown in FIG. When moved in the direction (the direction indicated by the arrow), the distal end portion 95B of the contact portion 95 is separated from the outer surface 31S of the chassis 31. At this time, since a predetermined distance L is secured between the end 93B of the main body 93 and the base end 95A of the contact part 95, the worker or the like places his or her hand on this part to By pulling the end 93B of the portion 93 to the side opposite to the chassis 31, such a separated state can be easily achieved. In this separated state, a gap is formed between the distal end portion 95B of the contact portion 95 and the chassis 31, so that the source substrate 45 can be inserted into the accommodation space S1 from this gap. Then, when the source board 45 is stored in the accommodation space S <b> 1 and the separated state is released by releasing the hand or the like, the distal end portion 95 </ b> B of the abutment portion 95 is again moved by the elastic restoring force of the main body portion 93. It comes into contact with the outer surface 31S. Thus, the source substrate 45 is accommodated in the accommodation space S1 between the outer surface 31S and the main body 93.

  The contact portion 95 is in contact with the outer surface 31S by an elastic force generated by the main body 93 toward the outer surface 31S of the chassis 31. The contact portion 95 is pressed against the outer surface 31 </ b> S of the chassis 31 by the elastic force of the main body portion 93 and is in contact with the outer surface 31 </ b> S, so that the source substrate 45 receives vibration or is pulled through the flexible substrate 47. However, it is stably accommodated without falling from the accommodation space S1.

  Further, since the source substrate 45 is held in the accommodation space S1 between the outer surface 31S of the chassis 31 and the main body 93 of the wire holder 90, the source substrate 45 is disposed between the members of the wire holder (between a pair of plate surfaces) as in the related art. The thickness of the wire holder can be reduced as compared with a configuration in which the source substrate is sandwiched between the two. Further, according to such a configuration, even in the outer surface 31S of the chassis 31 having the inclined surface and the flat surface, a housing space is formed between the outer surface 31S and the main body 93 of the wire holder 90. Can be installed.

  Furthermore, the wire holder 90 does not require an engaging member (for example, a portion that engages a pair of plate surfaces in the related art) for maintaining the contact state between the contact portion 95 and the outer surface 31S of the chassis 31. Therefore, the structure is simple and the manufacture is easy.

  In addition, since the wire holder 90 only needs to insert the source substrate into the gap generated between the wire holder 90 and the chassis 31 when housing the source substrate 45, the operation of housing the source substrate 45 is extremely simple. Further, it is not necessary to secure a long length of the flexible substrate 47 in advance for the convenience of the accommodation operation. In the prior art, in order to sandwich the source substrate between the pair of plate surfaces, it is necessary to secure the flexible substrate 47 longer by at least one plate surface.

  In addition, as shown by a two-dot chain line in FIG. 6, the distal end portion 95 of the contact portion 95 is at least an extension of the plate surface 91 </ b> A of the fixing portion 91 (shown by a one-dot chain line) before being attached to the chassis 31. ) It is preferable that it protrudes to reach the upper side. The abutting portion 95 is pressed against the outer surface 31S of the chassis 31 to abut against the liquid crystal display device having a different angle θ between the side portion 31B of the chassis 31 and the receiving portion 31C. A common wire holder 90 can be used, and parts can be shared.

The light propagates through the light guide plate 160 and is emitted toward the liquid crystal panel 20. The light guide plate 160 is made of a resin material that has a refractive index sufficiently higher than that of air and is almost transparent (excellent in light transmission). Like the liquid crystal panel 20 and the bottom 31A of the chassis 31, the light guide plate 160 has a rectangular shape that is horizontally long in a plan view, and has a plate shape larger in thickness than the optical sheet 33. The light guide plate 160 introduces the light emitted from the LED 52 from the long side surface (light incident surface) 161 and, while propagating the light inside, rises so as to face the optical sheet 33 side and raises the front surface ( The light is emitted from a light emission surface 162.

Thus, the wire holder 191 can be installed even in the portion of the chassis 131 having only a flat surface. In the wire holder 190, the projection 194 connecting the fixing part 191 and the main body part 193 is different from the first embodiment, and rises from the vicinity of the peripheral part on the contact part 195 side of the fixing part 191. When the protrusion 194 is raised from the peripheral edge in this manner, the fixing portion 191 can be prevented from entering the housing space S2 side, so that the housing space S2 can be expanded as compared with the first embodiment. Become.

  As shown in FIG. 10, a bar-shaped reinforcing rib 193A is formed integrally with the elongated plate-shaped main body 193 along the longitudinal direction.
