以下本発明の表示装置の実施例について、液晶表示装置を例に取り図面を参照して説明する。図１〜図３は第１の実施例を示している。図１は、液晶表示装置１の上下を反転させた状態の斜視図、図２は、図１の保護ケース４を外した状態の斜視図、図３は、図１のＡ−Ａに沿った要部の断面図である。この液晶表示装置１は、図に示すように、表示器本体２の後面に後方回路基板３とそれを覆う保護ケース４を固定している。   Hereinafter, embodiments of the display device of the present invention will be described with reference to the drawings, taking a liquid crystal display device as an example. 1 to 3 show a first embodiment. 1 is a perspective view of a state in which the liquid crystal display device 1 is turned upside down, FIG. 2 is a perspective view of a state in which a protective case 4 in FIG. 1 is removed, and FIG. 3 is a view along AA in FIG. It is sectional drawing of the principal part. In this liquid crystal display device 1, as shown in the figure, a rear circuit board 3 and a protective case 4 covering the rear circuit board 3 are fixed to the rear surface of the display main body 2.

表示器本体２は、図３に示すように、前面枠５と後面枠６との間に液晶表示パネル７とバックライト８を収容した構成としている。前面枠５と後面枠６は、鉄やアルミ板等の金属製で、板金加工によって一面が開口した箱状に形成している。前面枠５の中央には、表示パネル７が臨む矩形の窓が形成されている。そして、後面枠６の中に、バックライト８、中間枠９、表示パネル７を順次積層した後、その上から前面枠５を被せ、前面枠５の一部を後面枠６に係止することにより、表示器本体２の組立てが行われる。   As shown in FIG. 3, the display main body 2 has a configuration in which a liquid crystal display panel 7 and a backlight 8 are accommodated between a front frame 5 and a rear frame 6. The front frame 5 and the rear frame 6 are made of metal such as iron or aluminum plate, and are formed in a box shape with one surface opened by sheet metal processing. In the center of the front frame 5, a rectangular window facing the display panel 7 is formed. Then, after the backlight 8, the intermediate frame 9, and the display panel 7 are sequentially stacked in the rear frame 6, the front frame 5 is put thereon, and a part of the front frame 5 is locked to the rear frame 6. As a result, the display main body 2 is assembled.

表示パネル７は、駆動用の回路素子を直接ガラス基板の周辺部上に乗せたチップオンガラスタイプのものが用いられ、その一辺に沿って可撓性のフレキシブル回路基板１０を接続している。フレキシブル回路基板１０は、長さがパネル７の長辺と同等の長さで、巾が表示器本体２の厚み寸法よりも大きな帯状部分１１と、この帯状部分１１に接続したコネクタ用接続片１２を有している。帯状部分１１は、本体２の内側面、すなわち前面枠５側面と後面枠６側面の間の隙間を通って本体２の後面に至り、後面から後方に所定長さ突出する。この突出した部分は、保護ケース４の段差部分に案内されて内側に垂直に折れ曲がる。   The display panel 7 is of a chip-on-glass type in which a driving circuit element is directly mounted on a peripheral portion of a glass substrate, and a flexible circuit board 10 is connected along one side thereof. The flexible circuit board 10 has a strip portion 11 having a length equal to the long side of the panel 7 and a width larger than the thickness dimension of the display main body 2, and a connector connecting piece 12 connected to the strip portion 11. have. The band-shaped portion 11 reaches the rear surface of the main body 2 through an inner side surface of the main body 2, that is, a gap between the side surfaces of the front frame 5 and the rear frame 6, and protrudes rearward from the rear surface by a predetermined length. The protruding portion is bent inward vertically by being guided by the step portion of the protective case 4.

バックライト８は、導光板の側面に線状光源を配置したエッジライト式のもので構成しているが、パネル７が反射式の場合などには必ずしも設けなくても良い。中間枠９は、パネル７を位置決め保持するとともに、バックライト８がある場合はバックライト８との間隔を保持する役割を持つ樹脂製の枠で構成している。   The backlight 8 is configured by an edge light type in which a linear light source is arranged on the side surface of the light guide plate, but may not be necessarily provided when the panel 7 is a reflection type. The intermediate frame 9 is formed of a resin frame having a role of positioning and holding the panel 7 and, if there is a backlight 8, maintaining a distance from the backlight 8.

後方回路基板３は、図２に示すように、後面枠６の底面よりも若干面積が狭いプリント基板に第１、第２のコネクタ１３，１４と回路部品（図示せず）を装着して構成している。第１のコネクタ１３は、前記フレキシブル回路基板１０のコネクタ用接続片１２が接続される。第２のコネクタ１４は、周辺回路に接続されるフレキシブル回路基板のコネクタ用接続片（図示せず）が接続される。回路基板３の長辺の一方には、左右に一対の溝を形成することによって形成した係止用突起１５、１５を離間して配置している。長辺の他方はフレキシブル回路基板１０と対面する。回路基板３の短辺の一方には、位置決め用の矩形溝１６を形成し、短辺の他方には、ネジ止め用の半円溝１７を形成している。半円溝１７の近傍には、位置決め用の小孔１８を形成している。回路基板３の後面枠６と対向する面
には、グランド用パターンが複数箇所に形成されている。 As shown in FIG. 2, the rear circuit board 3 is configured by mounting the first and second connectors 13, 14 and circuit components (not shown) on a printed circuit board having a slightly smaller area than the bottom surface of the rear frame 6. are doing. The first connector 13 is connected to the connector connecting piece 12 of the flexible circuit board 10. The second connector 14 is connected to a connector connecting piece (not shown) of a flexible circuit board connected to a peripheral circuit. On one of the long sides of the circuit board 3, locking projections 15, 15 formed by forming a pair of grooves on the left and right sides are spaced apart. The other of the long sides faces the flexible circuit board 10. A rectangular groove 16 for positioning is formed on one of the short sides of the circuit board 3, and a semicircular groove 17 for screwing is formed on the other of the short sides. In the vicinity of the semicircular groove 17, a positioning small hole 18 is formed. On the surface facing the rear frame 6 of the circuit board 3, ground patterns are formed at a plurality of locations.

後面枠６には、前記回路基板３の位置決め用の第１、第２の爪１９，２０と、保護ケース４の位置決め用の第３の爪２１，２１と、回路基板３の位置決め用と保護ケース４の位置決め用を兼ねる第４の爪２２，２２が、底面の一部を後側に切り起こすことによって形成されている。第１、第２、第４の爪１９，２０，２２は、回路基板３の矩形溝１６、小孔１８、突起１５に対応して形成している。第４の爪２２には、回路基板３の厚さよりも広い隙間の孔２８が形成されている。後面枠６にはさらに、前記回路基板３のグランド用パターンと対向する微小突起２３が複数個形成されている。   The rear frame 6 has first and second claws 19 and 20 for positioning the circuit board 3, third claws 21 and 21 for positioning the protection case 4, and positioning and protection of the circuit board 3. Fourth claws 22, 22 also serving as positioning of the case 4 are formed by cutting and raising a part of the bottom surface to the rear side. The first, second, and fourth claws 19, 20, and 22 are formed corresponding to the rectangular grooves 16, the small holes 18, and the projections 15 of the circuit board 3. The fourth claw 22 is formed with a hole 28 having a gap wider than the thickness of the circuit board 3. The rear frame 6 is further formed with a plurality of minute projections 23 facing the ground pattern of the circuit board 3.

保護ケース４は、前面枠５や後面枠６と同様に金属を板金加工することにより形成され、一面が開放した箱状体をベースにして、その１つの側面（長側面）に沿って断面Ｌ字状片２４からなる段差構造を一体に形成した構成としている。このＬ字状片２４の水平部分２５は、本体２後面と微小空間を隔てて対面し、この空間部分に沿ってフレキシブル回路基板１０の帯状部分１１を内側に折り曲げることにより、所定の形状に整形保持する役割を持つ。Ｌ字状片２４の垂直部分２６は、前面枠５とフレキシブル回路基板１０の間に挿入される。保護ケース４のＬ字状片２４が形成された側には、第２コネクタ１４に外部のコネクタ接続片を挿脱するための差込口２７を形成している。保護ケース４の反対側の長側面側には、第４の爪２２の孔２８に係脱される爪２９が保護ケース４の一部を切り欠くことによって形成され、一方の短側面側には、第３の爪２１に係脱される屈曲片３０が、他方の短辺側には、半円溝１７と対応したネジ孔３１を有する係止片３２が一体に形成されている。   The protective case 4 is formed by sheet metal processing of metal in the same manner as the front frame 5 and the rear frame 6, and is based on a box-shaped body having one open side, and has a section L along one side (long side) thereof. A step structure including the character-shaped pieces 24 is integrally formed. The horizontal portion 25 of the L-shaped piece 24 faces the rear surface of the main body 2 with a small space therebetween, and is formed into a predetermined shape by bending the band-shaped portion 11 of the flexible circuit board 10 inward along the space. Has the role of holding. The vertical portion 26 of the L-shaped piece 24 is inserted between the front frame 5 and the flexible circuit board 10. On the side of the protective case 4 where the L-shaped piece 24 is formed, an insertion port 27 for inserting and removing an external connector connecting piece from the second connector 14 is formed. On the long side of the opposite side of the protective case 4, a claw 29 is formed by cutting out a part of the protective case 4 and engaged with the hole 28 of the fourth claw 22. On the other short side, a locking piece 32 having a screw hole 31 corresponding to the semicircular groove 17 is integrally formed on the other short side.

以下、上記液晶表示装置１の組立て手順について簡単に説明する。まず、後面枠６の中にバックライト８を配置し、その上に中間枠９を介在して液晶表示パネル７を積層し、その上から前面枠５を装着することによって表示器本体２を完成させる。ここで、フレキシブル回路基板１０の一端はパネル７に接続され、他端は本体２の後側に突出している。   Hereinafter, a procedure for assembling the liquid crystal display device 1 will be briefly described. First, the backlight 8 is arranged in the rear frame 6, the liquid crystal display panel 7 is laminated thereon with the intermediate frame 9 interposed, and the front frame 5 is mounted thereon, thereby completing the display main body 2. Let it. Here, one end of the flexible circuit board 10 is connected to the panel 7, and the other end protrudes to the rear side of the main body 2.

次に本体２の上下を反転し、回路基板３を本体裏側に装着する。ここで、第１の爪１９を矩形溝１６内に、第２の爪２０を小孔１８内に配置するとともに、第４の爪２２の孔２８に突起１５を挿入することで、回路基板３の位置決めが行われ、上下左右方向の移動が規制される。基板３の位置決めが終わると、コネクタ接続片１２を第１のコネクタ１３に接続する。   Next, the main body 2 is turned upside down, and the circuit board 3 is mounted on the back side of the main body. Here, the first claw 19 is arranged in the rectangular groove 16, the second claw 20 is arranged in the small hole 18, and the projection 15 is inserted into the hole 28 of the fourth claw 22, whereby the circuit board 3 is formed. Is performed, and the vertical and horizontal movements are restricted. When the positioning of the board 3 is completed, the connector connecting piece 12 is connected to the first connector 13.

次に、保護ケース４の取付けを行なう。まず、Ｌ字状片２４と反対側の長側面側に形成した爪２９を基板３の突起１５の上に重ねた状態で第４の爪２２の孔２８に差込んだ状態とするとともに、係止用屈曲片３０を第３の爪２１の孔に挿入した状態でＬ字状片２４の垂直部分２６を表示器本体２の側面隙間部分に差し込むことで、保護ケース４の仮取り付けを行なう。次に、１つのネジ（図示せず）を係止片３２の孔３１、半円溝１７を通って後面枠６にネジ止めすることにより、保護ケース４と回路基板３を表示器本体２に固定する。ネジ止め個所が一個所であるので、組立て作業性が良い。このネジ止めにより、後面枠６がその微小突起２３を介して回路基板３のグランド（接地電位）に接続されるとともに、保護ケース４と後面枠６の電気的な接続が行なわれることにより、表示装置１の外周
表面がグランドに保持されてシールドケースとして機能し、不要ノイズの発生を防ぐことができる。 Next, the protection case 4 is attached. First, the claw 29 formed on the long side surface opposite to the L-shaped piece 24 is inserted into the hole 28 of the fourth claw 22 with the claw 29 superimposed on the protrusion 15 of the substrate 3. The protection case 4 is temporarily attached by inserting the vertical portion 26 of the L-shaped piece 24 into the side gap of the display main body 2 with the stop bending piece 30 inserted into the hole of the third claw 21. Next, the protective case 4 and the circuit board 3 are attached to the display main body 2 by screwing one screw (not shown) to the rear frame 6 through the hole 31 of the locking piece 32 and the semicircular groove 17. Fix it. Since there is only one screwing point, assembly workability is good. By this screwing, the rear frame 6 is connected to the ground (ground potential) of the circuit board 3 via the minute projections 23, and the protective case 4 and the rear frame 6 are electrically connected, so that the display is performed. The outer peripheral surface of the device 1 is held at the ground and functions as a shield case, so that generation of unnecessary noise can be prevented.

保護ケース４の取り付けにより、フレキシブル回路基板１０の本体裏側に突出した部分がＬ字状片２４によってガイドされて内側に略垂直に折れ曲がる。ここで、突出寸法の短い帯状部分１１の一側は、比較的弾性復元力が大きいので、本体２裏側に垂直に折り曲げこれを保持するには比較的大きな力が要求されるが、保護ケース４のＬ字状片２４と表示器本体２とで挟持することにより、比較的容易に垂直に折り曲げ、これを保持することができる。その結果、フレキシブル回路基板１０を所定形状に整形して保持することができ、振動などによって外から力が加わったとしても、フレキシブル回路基板１０の接続部分にそれを外そうとする力が作用するのを防止することができる。   By attaching the protection case 4, the portion of the flexible circuit board 10 protruding to the back side of the main body is guided by the L-shaped piece 24 and bent inward substantially vertically. Here, since one side of the band-shaped portion 11 having a short protruding dimension has a relatively large elastic restoring force, a relatively large force is required to bend vertically to the back side of the main body 2 and hold it. Of the display main body 2 can be bent relatively easily and held vertically. As a result, the flexible circuit board 10 can be shaped and held in a predetermined shape, and even if a force is applied from the outside due to vibration or the like, a force for removing the force acts on the connection portion of the flexible circuit board 10. Can be prevented.

また、従来別途設けていた固定用テープとその貼り付け作業を不要とすることができるので、部品点数の削減と組み立て作業性を高めることができる。   Further, since the fixing tape and the attaching work conventionally separately provided can be eliminated, the number of parts can be reduced and the assembling workability can be improved.

さらにまた、後面枠６に形成した各種の爪によって回路基板３や保護ケース４の位置決め、固定などを行なう構成としているので、部品点数の削減や組立て工数の削減、さらに、装置の小型化や薄型化を図ることができる。   Furthermore, since the positioning and fixing of the circuit board 3 and the protective case 4 are performed by various claws formed on the rear frame 6, the number of parts and the number of assembling steps can be reduced. Can be achieved.

次に、爪２２の形状を変更した実施例について、図４、図５を参照して説明する。先の実施例では折り曲げ形成していた爪２２を、本実施例では絞り加工によって形成した爪３３とした点で両実施例は相違し、その他の構成は同じであるので、この爪３３の構造を中心に第２の実施例を説明する。ここで、図４は第２実施例の要部斜視図、図５は図１のＢ−Ｂに相当する部分の断面図である。係止用の爪３３は、絞り加工によって形成されている。そして、爪３３は、絞り加工によって円錐台形状とされた部分の一方の側面を開放して爪２９と基板３の突起１５を挿入する孔３４を形成し、残りの３方の側面３５，３６，３７を残すことによって、天面３８ならびに全体の平面形状がＤ型形状を成すように形成している。このように天面３８を３つの側面で支持するので、天面３８の支持強度を大幅に高めることができ、爪２９や基板３の突起１５を確実に位置決め保持することができる。   Next, an embodiment in which the shape of the claw 22 is changed will be described with reference to FIGS. The two embodiments differ in that the nail 22 formed by bending in the previous embodiment is replaced by a nail 33 formed by drawing in the present embodiment, and the other configurations are the same. The second embodiment will be described mainly. Here, FIG. 4 is a perspective view of a main part of the second embodiment, and FIG. 5 is a sectional view of a portion corresponding to BB in FIG. The locking claw 33 is formed by drawing. The claw 33 has a hole 34 into which the claw 29 and the projection 15 of the substrate 3 are inserted by opening one side surface of a portion formed into a truncated cone by drawing, and the remaining three side surfaces 35 and 36. , 37 are formed such that the top surface 38 and the entire planar shape form a D-shape. Since the top surface 38 is supported by the three side surfaces as described above, the supporting strength of the top surface 38 can be greatly increased, and the claw 29 and the projection 15 of the substrate 3 can be reliably positioned and held.

尚、孔３４と対面する側面３６には、後面枠６の保護ケース４によって覆われない部分に別途装着される後付け回路基板の爪（図５に一点鎖線で図示）を挿入することができるように、孔３９を形成している。したがって、第１の実施例では困難であった爪２２による後付け回路基板の保持がこの第２の実施例の爪３３によれば可能となるので、爪３３の有効利用を図ることができる。   In the side surface 36 facing the hole 34, a nail (shown by a dashed line in FIG. 5) of a retrofitted circuit board separately attached to a portion of the rear frame 6 not covered by the protective case 4 can be inserted. , A hole 39 is formed. Accordingly, the post-attachment circuit board can be held by the pawls 22, which is difficult in the first embodiment, by the pawls 33 of the second embodiment, so that the pawls 33 can be effectively used.

上記各実施例は液晶表示装置を例にとって説明したが、本発明は液晶表示装置以外の表示装置にも適用することができる。   Although the above embodiments have been described with reference to the liquid crystal display device as an example, the present invention can be applied to display devices other than the liquid crystal display device.
