　以上に説明した各部品の位置関係の概要を説明する。保持体５０の開口部の周囲に設けられた図示しない複数の爪部が前枠１２に設けられた穴部１２１に嵌ることにより、前枠１２が保持体５０の開口部に固定される。保持体５０と前枠１２との間に、前側から順番に液晶パネル１１、光学シート１５、導光板１６、図示しない反射シート、ホルダ３０および放熱板４０が積層された状態で保持される。 The outline of the positional relationship of each part explained above will be explained. The front frame 12 is fixed to the opening of the holding body 50 by fitting a plurality of claw portions (not shown) provided around the opening of the holding body 50 into the hole 121 provided in the front frame 12. Between the holding body 50 and the front frame 12, the liquid crystal panel 11, the optical sheet 15, the light guide plate 16, the reflection sheet (not shown), the holder 30, and the heat dissipation plate 40 are held in order from the front side.
　放熱板４０の前方に向かう部分の上側の面に、ＬＥＤ基板１７のＬＥＤを実装した面とは反対側の広面が接触している。ＬＥＤ基板１７のＬＥＤを実装した面と、導光板１６の長辺側の側面とは対向している。 The wide surface of the LED substrate 17 opposite to the surface on which the LED is mounted is in contact with the upper surface of the portion toward the front of the heat sink 40. The surface of the LED substrate 17 on which the LED is mounted faces the side surface on the long side of the light guide plate 16.
　表示装置１０の動作の概要を説明する。入力基板１４から入力された映像信号に基づいて、駆動基板２２に搭載された駆動回路が表示パネル２０を構成する各画素を制御する信号を出力する。信号は、ＦＰＣ２１を介して表示パネル２０を構成する各画素に伝わり、各画素が表示パネル２０の背面から照射された光を透過および遮蔽する。 An outline of the operation of the display device 10 will be described. Based on the video signal input from the input substrate 14, a drive circuit mounted on the drive substrate 22 outputs a signal for controlling each pixel constituting the display panel 20. The signal is transmitted to each pixel constituting the display panel 20 via the FPC 21, and each pixel transmits and shields light irradiated from the back surface of the display panel 20.
　ＬＥＤ基板１７に搭載された白色ＬＥＤが点灯して放射した光は、導光板１６の側面に入射する。入射した光は、導光板１６および図示しない反射シートの作用により、平面光になって導光板１６の前側の面から放射される。平面光が表示パネル２０の背面から前側に透過する。これにより、使用者は表示パネル２０に表示される映像を視認できる。 The light emitted from the white LED mounted on the LED substrate 17 is incident on the side surface of the light guide plate 16. The incident light becomes planar light and is emitted from the front surface of the light guide plate 16 by the action of the light guide plate 16 and a reflection sheet (not shown). The planar light is transmitted from the back surface of the display panel 20 to the front side. Thereby, the user can visually recognize the image displayed on the display panel 20.
　ＬＥＤ基板１７で発生した熱は、接触した部分から放熱板４０に伝わって、放熱板４０全体に拡散することにより、放熱が行われる。ホルダ３０は、放熱板４０と接触しないように導光板１６を保持する。ホルダ３０は、放熱板４０から導光板１６への熱の伝導を低減している。この構造により、導光板１６の熱膨張による映像の輝度ムラ等を低減できる。 The heat generated in the LED board 17 is transferred from the contacted portion to the heat radiating plate 40 and diffused throughout the heat radiating plate 40, whereby heat is radiated. The holder 30 holds the light guide plate 16 so as not to contact the heat radiating plate 40. The holder 30 reduces heat conduction from the heat radiating plate 40 to the light guide plate 16. With this structure, it is possible to reduce luminance unevenness of an image due to thermal expansion of the light guide plate 16.
　図６は、ホルダ３０と保持体５０とを組み合わせた状態の部分拡大図である。ホルダ３０と保持体５０との間に存在する放熱板４０は、保持体５０に隠れて見えない状態になっている。保持体５０の後ろ側の面の、鉤穴５５の上側の縁を繋いだ線よりも下の部分には、絶縁シート５２が設けられている。絶縁シート５２は、たとえばポリイミド製のフィルムであり、両面テープにより保持体５０に貼付されている。 FIG. 6 is a partially enlarged view of the state in which the holder 30 and the holding body 50 are combined. The heat radiating plate 40 existing between the holder 30 and the holding body 50 is hidden by the holding body 50 and cannot be seen. An insulating sheet 52 is provided on a portion of the rear surface of the holding body 50 below the line connecting the upper edges of the hole 55. The insulating sheet 52 is a film made of polyimide, for example, and is affixed to the holding body 50 with a double-sided tape.
　爪固定穴５１からは、抜け止め３１１が突出している。抜け止め３１１の根本側が、爪固定穴５１の上側の縁に引っかかって、保持体５０が後ろ側に動く事を防止している。また、抑え板３２の先端は保持体５０の前側の面に当接しており、保持体５０が前側に動くことを防止している。以上の構造により、ホルダ３０と保持体５０とが固定されている。 From the nail fixing hole 51, a retaining 311 protrudes. The base side of the retainer 311 is caught on the upper edge of the claw fixing hole 51 to prevent the holding body 50 from moving rearward. Further, the tip of the holding plate 32 is in contact with the front surface of the holding body 50 to prevent the holding body 50 from moving forward. With the above structure, the holder 30 and the holding body 50 are fixed.
　鉤穴５５からは、鉤３５が突出している。縦板部３５２と絶縁シート５２とは、平行である。縦板部３５２の前側の面と絶縁シート５２の後ろ側の面との間隔は、駆動基板２２の厚さよりも大きい。 鉤 The ridge 35 protrudes from the pit hole 55. The vertical plate portion 352 and the insulating sheet 52 are parallel. The distance between the front surface of the vertical plate portion 352 and the rear surface of the insulating sheet 52 is larger than the thickness of the drive substrate 22.
　図７は、駆動基板２２を固定した状態の部分拡大図である。図７は、表示パネル２０、光学シート１５、導光板１６、ホルダ３０、ＬＥＤ基板１７および放熱板４０を前枠１２と保持体５０との間に固定した状態を後ろ側から見た拡大図である。表示パネル２０の下側に設けられたＦＰＣ２１が後ろ側に屈曲して、駆動基板２２が縦板部３５２と保持体５０との間に挟まれている。 FIG. 7 is a partially enlarged view of the state where the drive substrate 22 is fixed. 7 is an enlarged view of the state in which the display panel 20, the optical sheet 15, the light guide plate 16, the holder 30, the LED substrate 17, and the heat radiating plate 40 are fixed between the front frame 12 and the holding body 50, as viewed from the rear side. is there. The FPC 21 provided on the lower side of the display panel 20 is bent rearward, and the drive substrate 22 is sandwiched between the vertical plate portion 352 and the holding body 50.

　前述のとおり、表示パネル２０の下辺にＦＰＣ２１が接続されている。ＦＰＣ２１はＵ字型に屈曲している。ＦＰＣ２１に接続された駆動基板２２は、保持体５０の後側の面と縦板部３５２との間に配置されている。絶縁シート５２は、駆動基板２２と保持体５０とが接触して、駆動基板２２に搭載された駆動回路がショートすることを防止する。 As described above, the FPC 21 is connected to the lower side of the display panel 20. The FPC 21 is bent in a U shape. The drive board 22 connected to the FPC 21 is disposed between the rear surface of the holding body 50 and the vertical plate portion 352. The insulating sheet 52 prevents the drive circuit mounted on the drive substrate 22 from being short-circuited when the drive substrate 22 and the holding body 50 come into contact with each other.
　図９は、表示装置１０の背面図である。表示装置１０の下部に、２枚の駆動基板２２が配置されている。駆動基板２２は、表示パネル２０の長辺の約二分の一の長さの長板状基板である。駆動基板２２は、２枚が表示パネル２０の長辺に沿って１列に配置されている。一枚の駆動基板２２に対して、１２枚のＦＰＣ２１が表示パネル２０の長辺に沿って一列に配列されている。 FIG. 9 is a rear view of the display device 10. Two drive substrates 22 are disposed below the display device 10. The drive substrate 22 is a long plate-like substrate having a length that is approximately one half of the long side of the display panel 20. Two drive substrates 22 are arranged in a line along the long side of the display panel 20. Twelve FPCs 21 are arranged in a row along the long side of the display panel 20 with respect to one drive substrate 22.
　駆動基板２２は、ほぼ全長にわたってＦＰＣ２１により表示パネル２０の下辺に接続されているので、左右方向には移動しない。駆動基板２２はＦＰＣ２１を介して前枠１２により支えられ、下方向に移動しない。駆動基板２２の上辺は鉤３５により後方向にも移動しない。したがって、駆動基板２２は図７から図９に示す所定の位置に保持されるので、輸送時の振動等による駆動基板２２およびＦＰＣ２１の損傷を防止することができる。 Since the drive substrate 22 is connected to the lower side of the display panel 20 by the FPC 21 over almost the entire length, it does not move in the left-right direction. The drive board 22 is supported by the front frame 12 via the FPC 21, and does not move downward. The upper side of the drive substrate 22 is not moved backward by the flange 35. Therefore, since the drive board 22 is held at the predetermined position shown in FIGS. 7 to 9, the drive board 22 and the FPC 21 can be prevented from being damaged due to vibration during transportation.
　本実施の形態によると、放熱板４０と接触しないように導光板１６を保持するホルダ３０が、駆動基板２２の保持部材を兼ねる。そのため、部品点数が少なく、組立が容易な、表示装置１０を提供することができる。 According to the present embodiment, the holder 30 that holds the light guide plate 16 so as not to come into contact with the heat radiating plate 40 also serves as a holding member of the drive substrate 22. Therefore, it is possible to provide the display device 10 with a small number of parts and easy assembly.
　縦板部３５２の形状は矩形板に限定しない。例えば半円板または下側の角部を切り欠いた六角形板等であっても良い。縦板部３５２を備えず、代わりに横板部３５１の後面に粘着材を備えても良い。このようにすることにより、粘着により駆動基板２２を保持する、板状の基板保持部を実現することができる。 The shape of the vertical plate portion 352 is not limited to a rectangular plate. For example, a semicircular plate or a hexagonal plate with a lower corner cut out may be used. Instead of providing the vertical plate portion 352, an adhesive material may be provided on the rear surface of the horizontal plate portion 351 instead. By doing in this way, the plate-shaped board | substrate holding part which hold | maintains the drive board | substrate 22 by adhesion | attachment is realizable.
　縦板部２５２を備えず、代わりに横板部３５１の下面に駆動基板２２の縁を挿入することが可能な２本のレールを設けても良い。このようにすることにより、レールの間に駆動基板２２を保持する基板保持部を実現することができる。 Instead of the vertical plate portion 252, two rails that can insert the edge of the drive substrate 22 may be provided on the lower surface of the horizontal plate portion 351 instead. By doing in this way, the board | substrate holding part which hold | maintains the drive board | substrate 22 between rails is realizable.
　ホルダ３０は、左右方向に２枚以上に分割されていても良い。ホルダ爪３１の数は、１２個に限定されない。ホルダ３０の長さおよび必要な固定強度に応じて、ホルダ爪３１の数を適宜選択することができる。鉤３５の数は２個に限定されない。駆動基板２２の長さに応じて、鉤３５の数を適宜選択することができる。 The holder 30 may be divided into two or more in the left-right direction. The number of holder claws 31 is not limited to twelve. The number of holder claws 31 can be appropriately selected according to the length of the holder 30 and the required fixing strength. The number of ridges 35 is not limited to two. According to the length of the drive substrate 22, the number of the ridges 35 can be selected as appropriate.
　表示パネル２０は上下方向の方が左右方向よりも長い矩形、正方形、三角形等の形状であっても良い。また、表示パネル２０は凹面または凸面形状であっても良い。駆動基板２２は、表示パネル２０の複数の辺に沿って配置されていても良い。このような場合には、各々の駆動基板２２の配置に合わせて、鉤３５を配置する。 The display panel 20 may have a shape such as a rectangle, a square, or a triangle that is longer in the vertical direction than in the horizontal direction. Further, the display panel 20 may be concave or convex. The drive substrate 22 may be disposed along a plurality of sides of the display panel 20. In such a case, the collar 35 is arranged in accordance with the arrangement of each driving substrate 22.
　保持体５０の背面側に、さらに外装部品を設けても良い。このようにして駆動基板２２およびＦＰＣ２１を覆うことにより、背面にＦＰＣ２１および駆動基板２２が露出せず、すっきりした外観の表示装置１０を実現することができる。 Further exterior parts may be provided on the back side of the holding body 50. By covering the drive substrate 22 and the FPC 21 in this manner, the FPC 21 and the drive substrate 22 are not exposed on the back surface, and the display device 10 with a clean appearance can be realized.
　ＦＰＣ２１の代わりに、平行に配置した多数のケーブルを長さ方向に融着したいわゆるフラットケーブルを使用しても良い。 Instead of the FPC 21, a so-called flat cable in which a number of cables arranged in parallel are fused in the length direction may be used.
　駆動基板２２は、ＦＰＣ２１上に駆動回路を構成する電子部品を実装したＳＯＦ（System On Film）（登録商標）基板であっても良い。このようにすると、駆動基板２２とＦＰＣ２１とを一体化して部品点数を更に減らすことができる。なお、この場合には、回路部品を実装した部分の背面に樹脂製の補強板を貼付すると、鉤３５により駆動基板２２を安定して保持することができる。 The drive board 22 may be an SOF (System On Film) (registered trademark) board in which electronic components constituting a drive circuit are mounted on the FPC 21. In this way, the drive board 22 and the FPC 21 can be integrated to further reduce the number of parts. In this case, the drive board 22 can be stably held by the flange 35 when a resin reinforcing plate is attached to the back surface of the portion where the circuit components are mounted.
　表示装置１０は、コンピューター用、ゲーム機用、デジタルサイネージ用等の様々な用途に使用できる。 The display device 10 can be used for various purposes such as for computers, game machines, and digital signage.
　表示装置１０には、図示しないスピーカーを設けても良い。また、音声信号出力端子を設けて、外部スピーカーに音声信号を出力しても良い。 The display device 10 may be provided with a speaker (not shown). Further, an audio signal output terminal may be provided to output an audio signal to an external speaker.
　表示装置１０をテレビジョン受信機として使用する場合には、入力基板１４にテレビジョン放送のアンテナを接続するアンテナ端子およびテレビジョン放送の電波を受信するチューナ回路を備えたテレビジョン受信部を搭載する。テレビジョン受信部が受信した放送信号に所定の処理を行い、映像信号と音声信号とに分離する。映像信号に基づき表示パネル２０に映像を表示する。音声信号は図示しないスピーカーまたは音声出力端子を介して外部スピーカーから出力する。 When the display device 10 is used as a television receiver, a television receiver having an antenna terminal for connecting a television broadcast antenna and a tuner circuit for receiving a television broadcast radio wave is mounted on the input board 14. . A predetermined process is performed on the broadcast signal received by the television receiver, and the broadcast signal is separated into a video signal and an audio signal. An image is displayed on the display panel 20 based on the image signal. The audio signal is output from an external speaker via a speaker or an audio output terminal (not shown).
　なお、入力基板１４にアンテナ端子の代わりにテレビジョン放送受信用のアンテナを搭載しても良い。 It should be noted that an antenna for receiving a television broadcast may be mounted on the input board 14 instead of the antenna terminal.
　このようにすると、部品点数が少なく、組立が容易な、テレビジョン受信機を提供する事ができる。 In this way, it is possible to provide a television receiver with a small number of parts and easy assembly.
