Description

表示装置及びテレビジョン受信機Display device and television receiver
　本発明は、正面に映像を表示する液晶パネルの周縁部を背面側から支える支持部を備える表示装置及びテレビジョン受信機に関する。 The present invention relates to a display device and a television receiver including a support portion that supports a peripheral portion of a liquid crystal panel that displays an image on the front side from the back side.
　表示画面の大きさに比べて室内の占有面積が小さい薄型の表示装置は、限られた室内空間を有効に利用することができることから、一般に広く普及している。この種の表示装置の構造として、以下のものが提案され公知となっている。表示装置は例えば正面に映像を表示する液晶パネルの周縁部を背面側から支える支持部と、液晶パネルの背面に光を照射するバックライトの筐体とを備える。該筐体は側縁に支持部を重ね、夫々の重なり部分に設けた係合突起と係合孔とを係合させて固定し、液晶パネルと筐体に取付けた回路基板とを、重なり部分に沿わせて湾曲するフレキシブル基板により接続しているものがある。さらに筺体はビスにより支持部を筺体に固定した構造を備えるものもある（例えば特許文献１）。 A thin display device that occupies a small area compared to the size of the display screen is generally widely used because it can effectively use a limited indoor space. As the structure of this type of display device, the following has been proposed and publicly known. The display device includes, for example, a support portion that supports a peripheral portion of a liquid crystal panel that displays an image on the front surface from the back side, and a backlight housing that irradiates light on the back surface of the liquid crystal panel. The casing has a support portion overlapped on a side edge, and an engagement protrusion and an engagement hole provided in each overlapping portion are engaged and fixed, and the liquid crystal panel and the circuit board attached to the casing are overlapped. Some are connected by a flexible substrate that curves along the line. Further, some cases have a structure in which a support portion is fixed to the case with screws (for example, Patent Document 1).

　特許文献１に記載の表示装置は、フレキシブル基板と係合突起又はビス等の突起部とが接触することを防止するためフレキシブル基板と突起部の位置が接触しないように各種部品を配置している。 In the display device described in Patent Document 1, various components are arranged so that the position of the flexible substrate and the protruding portion do not contact with each other in order to prevent the flexible substrate and the protruding portion such as the engagement protrusion or the screw from contacting each other. .
　ところで近年、表示装置において部品の統一化の観点から同一の部品を他の表示装置に使用することが求められている。しかし、複数種の表示装置で同一の表示パネルを使用した場合、支持部に設けられた突起部とフレキシブル基板との距離が近いときがある。このため、表示装置が外力によって振動した場合、突起部がフレキシブル基板に接触することでフレキシブル基板を損傷させるおそれがあった。 Incidentally, in recent years, it has been required to use the same parts for other display devices from the viewpoint of unifying the parts in the display devices. However, when the same display panel is used in a plurality of types of display devices, the distance between the protrusion provided on the support and the flexible substrate may be short. For this reason, when a display apparatus vibrates with external force, there exists a possibility that a flexible substrate may be damaged because a projection part contacts a flexible substrate.
　本発明は斯かる事情に鑑みてなされたものであり、その目的とするところは、フレキシブル基板の損傷を防止する表示装置及びテレビジョン受信機を提供することにある。 The present invention has been made in view of such circumstances, and an object thereof is to provide a display device and a television receiver that prevent damage to a flexible substrate.

As shown in the figure, the engagement plate 33 provided at each position is provided with an engagement hole 331 having a rectangular cross section extending in the left-right direction along the longitudinal direction of the chassis member 30. Thick portions 332 are provided on the left and right sides of 331 along the respective side edges.
　このように構成されたシャーシ部材３０は、図３に示す如く、前板３１を前方に向け、側板３２を下方に向けて配置される。このとき係合板３３は、側板３２の下位置で適宜の間隔を隔てて該延出部と平行に突設されている。また係合孔３３１の左右に位置する肉厚部３３２は、係合板３３の下面から下方に延びる。 As shown in FIG. 3, the chassis member 30 configured in this way is arranged with the front plate 31 facing forward and the side plate 32 facing downward. At this time, the engaging plate 33 protrudes in parallel with the extending portion at an appropriate interval below the side plate 32. Further, the thick portions 332 located on the left and right of the engagement hole 331 extend downward from the lower surface of the engagement plate 33.
　バックライトシャーシ４にシャーシ部材３０を取り付ける方法は以下の通りである。図３に示すようにシャーシ部材３０はバックライトシャーシ４の側壁４１に側板３２を当接し、左右方向に移動させて側板３２と係合板３３との間に側壁４１を摺動挿入し、側壁の突出部側の面から突出する係合突起４２と係合孔３３１とを係合することによりバックライトシャーシ４の下端に側板３２を固定し、バックライトシャーシ４に取り付けられる。 The method of attaching the chassis member 30 to the backlight chassis 4 is as follows.

At this time, since the plurality of SOFs 5 can be brought into contact with the thick portion 332 to avoid contact with the engaging protrusions 42, damage to the SOFs 5 by the engaging protrusions 42 can be prevented. Further, the thick portion 332 serves as a reinforcement for the engagement plate 33.
　またバックライトシャーシ４とパネルシャーシ３とはビスで固定される場合がある。バックライトシャーシ４とパネルシャーシ３とをビスで固定する場合、ビスがＳＯＦ５に接触することでＳＯＦ５が損傷することがある。本実施形態における表示装置は複数のＳＯＦ５を肉厚部３３２に当接することでビスとの接触を避けることができるため、ビスによるＳＯＦ５の損傷を防止することができる。 Also, the backlight chassis 4 and the panel chassis 3 may be fixed with screws. When the backlight chassis 4 and the panel chassis 3 are fixed with screws, the SOF 5 may be damaged by the screws coming into contact with the SOF 5. Since the display device in the present embodiment can avoid contact with the screws by bringing a plurality of SOFs 5 into contact with the thick portion 332, damage to the SOFs 5 due to the screws can be prevented.
