Description

表示装置Display device
　画像を表示する表示パネルと、表示パネルに光を照射するバックライトを備える表示装置に関する。 [Technical Field] The present invention relates to a display device including a display panel for displaying an image and a backlight for irradiating the display panel with light.
　近年、液晶テレビションなどの表示装置が広く普及されている。このような表示装置は画像を表示する表示パネル、表示面の反対面から表示パネルに光を照射するバックライトを備える。バックライトは導光板を備えており、該導光板は光源からの光を内部で平面的に伝播させ、各種の作用を持つ複数の光学シートを介して画像を表示する表示パネルに向けて、光を照射する。 In recent years, display devices such as liquid crystal televisions are widely used. Such a display device includes a display panel that displays an image, and a backlight that irradiates the display panel with light from the opposite side of the display surface. The backlight includes a light guide plate. The light guide plate propagates light from the light source in a planar manner and emits light toward a display panel that displays an image through a plurality of optical sheets having various functions. Irradiate.
　これら複数の光学シートは導光板とともに、一面が開口された箱状をなす支持部材に支持される。光学シート及び導光板はその周縁を光の出射面から収容部方向に押圧する押圧部材により押圧され、押圧部材と支持部材とで挟持固定される。さらに、偏光板と表示パネルが導光板及び光学シートに載置され、その周縁を額縁状の枠体（ベゼル）と押圧部材とにより挟持固定される。支持部材、押圧部材、枠体は、ビスにより互いに固定される。
　引用文献１には、フレーム（枠体）とバックライトシャーシ（支持部材）とが、ビスにより固定してある表示装置が記載されている。 The plurality of optical sheets are supported together with the light guide plate by a supporting member having a box shape with one surface opened. The optical sheet and the light guide plate are pressed by a pressing member that presses the periphery of the optical sheet and the light guide plate from the light emitting surface toward the housing portion, and is sandwiched and fixed by the pressing member and the support member. Furthermore, the polarizing plate and the display panel are placed on the light guide plate and the optical sheet, and the periphery thereof is sandwiched and fixed by a frame-like frame (bezel) and a pressing member. The support member, the pressing member, and the frame are fixed to each other with screws.

　ところで、近年、表示装置の大型化に伴い、ビスの本数が増加し、ビス締めの作業時間が増大している。また、ビスによる固定は、ビス孔付近の固定力が強くなるという点固定である。そのため、表示パネル、光学シート、及び導光板には固定するための力が一様に掛からない。それにより、表示パネルのセル厚ムラ、光学シートの撓み、導光板の歪みが発生し、表示品位の悪化につながっている。 By the way, in recent years, with the increase in size of the display device, the number of screws has increased, and the work time for screw tightening has increased. Further, the fixing with the screw is a point fixing in which the fixing force near the screw hole is increased. Therefore, the fixing force is not uniformly applied to the display panel, the optical sheet, and the light guide plate. As a result, cell thickness unevenness of the display panel, bending of the optical sheet, and distortion of the light guide plate are generated, leading to deterioration of display quality.
　本発明は、上述のごとき事情に鑑みてなされたものであり、磁気吸引力を利用して、支持部材及び押圧部材（パネル支持部材）並びに押圧部材（パネル支持部材）及び枠体を固定することにより固定力を一様にし、表示品位を保った表示装置を提供することを目的とする。 The present invention has been made in view of the circumstances as described above, and uses a magnetic attractive force to fix a support member, a pressing member (panel support member), a pressing member (panel support member), and a frame. Accordingly, an object of the present invention is to provide a display device in which the fixing force is made uniform and the display quality is maintained.

　以下に、本発明の実施の形態に係る表示装置を、いわゆる液晶表示パネルを備える液晶表示装置を例として、図面に基づいて詳述する。 Hereinafter, a display device according to an embodiment of the present invention will be described in detail with reference to the drawings, taking a liquid crystal display device including a so-called liquid crystal display panel as an example.
（実施の形態１）
　実施の形態１における液晶表示装置１の外観を示す斜視図である。液晶表示装置１はバックライト４、液晶表示部５、ベゼル（枠体）７及びスタンド８を含む。液晶表示部５は液晶表示パネル（表示パネル）を含み、液晶表示パネルは一面に画像を表示する。バックライト４は液晶表示パネルの他面に光を照射する。ベゼル７は、液晶表示パネルの表示面の周縁を押圧し、液晶表示パネルを挟持固定する。スタンド８は、液晶表示装置１をテーブル等の平面に立てて載置するためのものである。 (Embodiment 1)
1 is a perspective view showing an appearance of a liquid crystal display device 1 in Embodiment 1. FIG. The liquid crystal display device 1 includes a backlight 4, a liquid crystal display unit 5, a bezel (frame body) 7 and a stand 8. The liquid crystal display unit 5 includes a liquid crystal display panel (display panel), and the liquid crystal display panel displays an image on one side. The backlight 4 irradiates the other surface of the liquid crystal display panel with light. The bezel 7 presses the periphery of the display surface of the liquid crystal display panel, and clamps and fixes the liquid crystal display panel. The stand 8 is for placing the liquid crystal display device 1 on a flat surface such as a table.
　図２は液晶表示装置１主要部の断面図である。液晶表示装置１は前述した構成に加え、導光板２、導光板２の背面に位置する反射シート３、クッション材６１を介して導光板２を押圧して固定するシャーシ（パネル支持部材）６を含む。 FIG. 2 is a cross-sectional view of the main part of the liquid crystal display device 1. In addition to the configuration described above, the liquid crystal display device 1 includes a light guide plate 2, a reflection sheet 3 located on the back surface of the light guide plate 2, and a chassis (panel support member) 6 that presses and fixes the light guide plate 2 through a cushion material 61. Including.
　バックライト４は、バックライトシャーシ（支持部材）４１、導光板２、反射シート３を含む。バックライトシャーシ４１は鋼板などの軟磁性材料（軟磁性体）で形成され、一面が開口された箱型をなしている。 The backlight 4 includes a backlight chassis (support member) 41, a light guide plate 2, and a reflection sheet 3. The backlight chassis 41 is formed of a soft magnetic material (soft magnetic material) such as a steel plate, and has a box shape with one surface opened.
　導光板２は、例えば透明度の高い矩形板状のアクリル樹脂からなり、所定の厚みを有している。導光板２は側面から入射される光を平面光に変えて、広面から出射する。 The light guide plate 2 is made of, for example, a highly transparent rectangular plate-shaped acrylic resin and has a predetermined thickness. The light guide plate 2 changes the light incident from the side surface into plane light and emits it from the wide surface.
　反射シート３は、矩形状のシートである。反射シート３は外部から入射した光を乱反射する。反射シート３は厚みを除き、導光板２と略等しい寸法としてある。 The reflection sheet 3 is a rectangular sheet. The reflection sheet 3 irregularly reflects light incident from the outside. The reflective sheet 3 has substantially the same dimensions as the light guide plate 2 except for the thickness.
　バックライトシャーシ４１の開口と対向する板状部に、まず、反射シート３が載置され、次に、導光板２が載置される。 First, the reflection sheet 3 is placed on the plate-like portion facing the opening of the backlight chassis 41, and then the light guide plate 2 is placed.
　シャーシ６は、全体が矩形枠状をなしている。シャーシ６は磁石にて形成してある。シャーシ６の各辺を構成する部材の断面は略Ｌ字形をなしている。Ｌ字を構成する一方の板状部（固定部）６ａは、導光板２の側面と略平行としてある。Ｌ字を構成する他方の板状部（パネル支持部）６ｂは導光板２の一面周縁を、クッション６１を介してバックライトシャーシ４１側に押圧している。それにより、導光板２及び反射シートをシャーシ６とバックライトシャーシ４１とで挟持固定している。シャーシ６は磁石で形成し、バックライトシャーシ４１は軟磁性材料で形成してあるので、磁気吸引力により、シャーシ６とバックライトシャーシ４１とが固定される。 The chassis 6 has a rectangular frame shape as a whole. The chassis 6 is formed of a magnet. The cross section of the member constituting each side of the chassis 6 is substantially L-shaped. One plate-like portion (fixed portion) 6 a constituting the L shape is substantially parallel to the side surface of the light guide plate 2. The other plate-like part (panel support part) 6 b constituting the L-shape presses the peripheral edge of the light guide plate 2 toward the backlight chassis 41 via the cushion 61. Thereby, the light guide plate 2 and the reflection sheet are sandwiched and fixed between the chassis 6 and the backlight chassis 41. Since the chassis 6 is formed of a magnet and the backlight chassis 41 is formed of a soft magnetic material, the chassis 6 and the backlight chassis 41 are fixed by a magnetic attractive force.
　液晶表示部５は液晶表示パネル５１、偏光板５２、５２、第１拡散シート５３、プリズムシート５４、第２拡散シート５５を含む。 The liquid crystal display unit 5 includes a liquid crystal display panel 51, polarizing plates 52 and 52, a first diffusion sheet 53, a prism sheet 54, and a second diffusion sheet 55.
　液晶表示パネル５１は一面から光の照射を受け、光を液晶により制御することにより、他面に画像を表示する。 The liquid crystal display panel 51 receives light from one surface and controls the light with liquid crystal to display an image on the other surface.
　偏光板５２、５２は通過させる光の向きが互いに９０度異なるような向きで、液晶表示パネル５１を挟んでいる。 The polarizing plates 52 and 52 sandwich the liquid crystal display panel 51 in such a direction that the directions of light passing through are different from each other by 90 degrees.
　第１拡散シート５３、第２拡散シート５５は光を拡散する。プリズムシート５４は光を集光する。 The first diffusion sheet 53 and the second diffusion sheet 55 diffuse light. The prism sheet 54 collects light.
　導光板２の反射シート３と接する面の反対面に、第２拡散シート５５、プリズムシート５４、第1拡散シート５３の順に、光学シートが載置され、一組の偏光板５２に挟まれた液晶表示パネル５１が載置される。 The optical sheet is placed in the order of the second diffusion sheet 55, the prism sheet 54, and the first diffusion sheet 53 on the surface opposite to the surface in contact with the reflection sheet 3 of the light guide plate 2, and sandwiched between a pair of polarizing plates 52. A liquid crystal display panel 51 is placed.
　ベゼル７はシャーシ６と同様に、全体が矩形枠状をなしている。ベゼル７は軟磁性材料で形成してある。ベゼル７の各辺を構成する部材は断面略Ｌ字形をなしている。Ｌ字を構成する一方の板状部は、導光板２の側面と略平行としてある。Ｌ字を構成する他方の板状部は液晶表示パネル５１の他面と略平行である。当該板状部とシャーシ６の板状部６ｂ（パネル支持部）とで液晶表示パネル５１の周縁を挟むことにより、液晶表示パネル５１が挟持固定される。ベゼル７は軟磁性材料で形成してあり、シャーシ６は磁石で形成してあるので、磁気吸引力により、ベゼル７とシャーシ６とが固定される。
　なお、シャーシ６は液晶表示パネル５１を支持し、ベゼル７とで挟持固定するのが、主とした機能である。したがって、上述の説明においては、シャーシ６の板状部６ｂ（パネル支持部）は導光板２を押圧している構造としたが、それに限られない。導光板２をシャーシ６を用いずに、固定しても良い。 Similar to the chassis 6, the bezel 7 has a rectangular frame shape as a whole. The bezel 7 is made of a soft magnetic material. Members constituting each side of the bezel 7 have a substantially L-shaped cross section. One plate-like portion constituting the L shape is substantially parallel to the side surface of the light guide plate 2. The other plate-like portion constituting the L shape is substantially parallel to the other surface of the liquid crystal display panel 51. The liquid crystal display panel 51 is sandwiched and fixed by sandwiching the periphery of the liquid crystal display panel 51 between the plate-like portion and the plate-like portion 6 b (panel support portion) of the chassis 6. Since the bezel 7 is made of a soft magnetic material and the chassis 6 is made of a magnet, the bezel 7 and the chassis 6 are fixed by a magnetic attractive force.
The main function of the chassis 6 is to support the liquid crystal display panel 51 and sandwich and fix it with the bezel 7. Therefore, in the above description, the plate-like portion 6b (panel support portion) of the chassis 6 is configured to press the light guide plate 2, but is not limited thereto. The light guide plate 2 may be fixed without using the chassis 6.
　液晶表示装置１は次のように動作する。図示しない光源部から出射した光は、導光板２の一側面から入光する。導光板２の内部を通った光及び反射シート３で反射した光は液晶表示パネル５１と対向する面から出射する。 The liquid crystal display device 1 operates as follows. Light emitted from a light source unit (not shown) enters from one side surface of the light guide plate 2. The light that has passed through the inside of the light guide plate 2 and the light that has been reflected by the reflection sheet 3 is emitted from the surface facing the liquid crystal display panel 51.
　導光板２から出射された光は、第２拡散シート５５により拡散され、プリズムシート５４に入射する。プリズムシート５４は入射した光を集光して液晶表示パネル５２に向けて出射させる。プリズムシート５４から出射される光は、プリズムシート５４に対して垂直に第１拡散シート５３へ入射される。第１拡散シート５３は、プリズムシート５４を介して入射される光を更に拡散させてより均一な輝度分布にして液晶表示パネル５１に向けて出射させる。 The light emitted from the light guide plate 2 is diffused by the second diffusion sheet 55 and enters the prism sheet 54. The prism sheet 54 condenses incident light and emits it toward the liquid crystal display panel 52. Light emitted from the prism sheet 54 enters the first diffusion sheet 53 perpendicular to the prism sheet 54. The first diffusion sheet 53 further diffuses the light incident through the prism sheet 54 and emits it toward the liquid crystal display panel 51 with a more uniform luminance distribution.
　第１拡散シート５３から出射した光は偏光板５２により所定の方向に振動する光のみが、液晶表示パネル５１の一面に入射する。入射した光は液晶表示パネル５１を構成する液晶により光の振動方向が変えられた場合は、他面に配された偏光板５２を通過し、出射する。振動の方向を変えられない光は他面に配された偏光板５２により遮断される。このような光の制御により、液晶表示パネル５１の他面（表示面）に画像が形成される。 Only the light emitted from the first diffusion sheet 53 oscillates in a predetermined direction by the polarizing plate 52 is incident on one surface of the liquid crystal display panel 51. When the vibration direction of the light is changed by the liquid crystal constituting the liquid crystal display panel 51, the incident light passes through the polarizing plate 52 disposed on the other surface and is emitted. The light whose direction of vibration cannot be changed is blocked by the polarizing plate 52 disposed on the other surface. By such light control, an image is formed on the other surface (display surface) of the liquid crystal display panel 51.
　次にバックライトシャーシ４１、シャーシ６、ベゼル７同士の固定方法について説明する。図３は従来技術による液晶表示装置主要部の断面図である。図４は従来技術による液晶表示装置のビス止め位置の一例を示す説明図である。図３に示すように、バックライトシャーシ４１、シャーシ６、ベゼル７はビスＢにより互いに固定される。図４に示すように、液晶表示装置全体では、１２本のビスＢ、Ｂ、…により、バックライトシャーシ４１、シャーシ６、ベゼル７を互いに固定することとなる。それにより、組立工数の増大を招いている。また、ビスの近辺とそれ以外の箇所では加わる力が異なる力のムラがあるため、液晶表示パネルのセル厚ムラや、光学シートの撓みが発生し、表示品位悪化の原因となる。 Next, a method for fixing the backlight chassis 41, the chassis 6, and the bezel 7 will be described. FIG. 3 is a cross-sectional view of a main part of a liquid crystal display device according to the prior art. FIG. 4 is an explanatory view showing an example of a screwing position of a liquid crystal display device according to the prior art. As shown in FIG. 3, the backlight chassis 41, the chassis 6, and the bezel 7 are fixed to each other by screws B. As shown in FIG. 4, in the entire liquid crystal display device, the backlight chassis 41, the chassis 6, and the bezel 7 are fixed to each other by twelve screws B, B,. As a result, the number of assembly steps is increased. In addition, since there is unevenness in the force applied in the vicinity of the screw and other parts, uneven cell thickness of the liquid crystal display panel and bending of the optical sheet occur, which causes display quality deterioration.
　そこで本実施の形態では、図２に示すようにビスを廃している。そして、シャーシ６を磁石で構成している。また、バックライトシャーシ４１及びベゼル７を磁石に吸引される性質を持つ鉄などの軟磁性材料で形成する。このようにすれば、バックライトシャーシ４１、シャーシ６、ベゼル７を磁力により互いに固定することが可能となる。この方法においては面同士が固定されるので、固定する力にムラは生じにくい。したがって、液晶表示パネル５１のセル厚ムラや、光学シート５３、５４、５５の撓みの発生を防ぎ、表示品位を保つことが可能となる。 Therefore, in this embodiment, the screws are discarded as shown in FIG. And the chassis 6 is comprised with the magnet. Further, the backlight chassis 41 and the bezel 7 are made of a soft magnetic material such as iron having a property of being attracted by a magnet. In this way, the backlight chassis 41, the chassis 6, and the bezel 7 can be fixed to each other by magnetic force. In this method, since the surfaces are fixed, unevenness is hardly generated in the fixing force. Therefore, the cell thickness unevenness of the liquid crystal display panel 51 and the bending of the optical sheets 53, 54, and 55 can be prevented, and the display quality can be maintained.
　なお、磁力による固定で不十分な場合は、ビスなどの機械的な固定も併用しても良い。補助的にビス固定を行う場合であってもビスの本数は従来よりも少なくて済み、組み立て工数の低減が可能となる。また、磁力による固定と併用であるから、力のムラも最小限とすることが可能である。 In addition, when fixing by magnetic force is insufficient, mechanical fixing such as screws may be used together. Even in the case of auxiliary screw fixing, the number of screws is smaller than in the prior art, and the assembly man-hour can be reduced. In addition, since it is used together with fixation by magnetic force, unevenness of force can be minimized.
（変形例１）
　実施の形態１ではシャーシ６のみを磁石で形成したが、シャーシ６に加えて、ベゼル７についても磁石により構成しても良い。そのことにより、シャーシ６及びベゼル７との結合は実施の形態１より強固なものとなる。全体の構造は実施の形態１と同様であるから、説明を省略する。 (Modification 1)
In the first embodiment, only the chassis 6 is formed of magnets. However, in addition to the chassis 6, the bezel 7 may be configured of magnets. As a result, the connection between the chassis 6 and the bezel 7 is stronger than that in the first embodiment. Since the entire structure is the same as that of the first embodiment, description thereof is omitted.
　変形例１では、シャーシ６及びベゼル７との結合は実施の形態１より強固なものとなり、液晶表示パネル５１のセル厚ムラや位置ズレを効果的に防ぐことが可能となる。 In the first modification, the connection between the chassis 6 and the bezel 7 is stronger than that in the first embodiment, and the cell thickness unevenness and the positional deviation of the liquid crystal display panel 51 can be effectively prevented.
（変形例２）
　変形例２では、シャーシ６に加えて、バックライトシャーシ４１を磁石により構成する。そのことにより、シャーシ６及びバックライトシャーシ４１との結合は実施の形態１よりも強固なものとなる。全体の構造は実施の形態１と同様であるから、説明を省略する。 (Modification 2)
In the modified example 2, in addition to the chassis 6, the backlight chassis 41 is configured by a magnet. As a result, the connection between the chassis 6 and the backlight chassis 41 is stronger than in the first embodiment. Since the entire structure is the same as that of the first embodiment, description thereof is omitted.
　変形例２では、シャーシ６及びバックライトシャーシ４１との結合は実施の形態１より強固なものとなり、導光板２及び反射シート３の位置ズレを効果的に防ぐことが可能となる。 In the second modification, the connection between the chassis 6 and the backlight chassis 41 is stronger than that in the first embodiment, and the positional deviation between the light guide plate 2 and the reflection sheet 3 can be effectively prevented.
（変形例３）
　変形例３では、シャーシ６に加えて、バックライトシャーシ４１及びベゼル７についても磁石で構成する。そのことにより、シャーシ６及びベゼル７との結合並びにシャーシ６及びバックライトシャーシ４１との結合をより強固とすることが可能となる。それにより、固定される力のムラによる液晶表示パネル５１のセル厚ムラ、位置ずれによる光学シート５３、５４、５５の撓みが発生を防ぐことが、より確実に可能となる。それにより、表示品位を保つことが可能となる。 (Modification 3)
In Modification 3, in addition to the chassis 6, the backlight chassis 41 and the bezel 7 are also composed of magnets. As a result, the connection between the chassis 6 and the bezel 7 and the connection between the chassis 6 and the backlight chassis 41 can be further strengthened. Accordingly, it is possible to more reliably prevent the occurrence of the cell thickness unevenness of the liquid crystal display panel 51 due to the unevenness of the fixing force and the bending of the optical sheets 53, 54, 55 due to the positional deviation. Thereby, display quality can be maintained.
（変形例４）
　上述の例では、シャーシ６を磁石で構成していた。変形例４では、シャーシ６を軟磁性材料で構成し、バックライトシャーシ４１及びベゼル７を磁石で構成する。シャーシ６及びバックライトシャーシ４１の結合、並びにシャーシ６及びベゼル７との結合は、実施の形態１と同様な強固さを実現可能である。全体の構造は実施の形態１と同様である。 (Modification 4)
In the above example, the chassis 6 is made of a magnet. In Modification 4, the chassis 6 is made of a soft magnetic material, and the backlight chassis 41 and the bezel 7 are made of magnets. The coupling between the chassis 6 and the backlight chassis 41 and the coupling between the chassis 6 and the bezel 7 can achieve the same strength as in the first embodiment. The overall structure is the same as in the first embodiment.
（実施の形態２）
　実施の形態１、変形例１から３ではシャーシ６を磁石で構成していたが、実施の形態２では軟磁性材料で構成する。シャーシ６のベゼル７と接触する面及びバックライトシャーシ４１と接触する面に磁石を取り付ける。図５は実施の形態２に係る液晶表示装置主要部の断面図である。シャーシ６のベゼル７と接触する面に磁石６２が取り付けられている。シャーシ６のバックライトシャーシ４１と接触する面に磁石６３が取り付けられている。シャーシ６は軟磁性材料で形成してあるので、磁石６２及び６３は磁気吸引力により、シャーシ６に固定される。バックライトシャーシ４１、ベゼル７は磁石又は軟磁性材料で構成する。 (Embodiment 2)
In the first embodiment and the first to third modifications, the chassis 6 is composed of a magnet. In the second embodiment, the chassis 6 is composed of a soft magnetic material. Magnets are attached to the surface of the chassis 6 that contacts the bezel 7 and the surface that contacts the backlight chassis 41. FIG. 5 is a cross-sectional view of the main part of the liquid crystal display device according to the second embodiment. A magnet 62 is attached to the surface of the chassis 6 that contacts the bezel 7. A magnet 63 is attached to the surface of the chassis 6 that contacts the backlight chassis 41. Since the chassis 6 is made of a soft magnetic material, the magnets 62 and 63 are fixed to the chassis 6 by a magnetic attractive force. The backlight chassis 41 and the bezel 7 are made of magnets or soft magnetic materials.
　シャーシ６とバックライトシャーシ４１との固定は磁石６３を介して行われる。シャーシ６とベゼル７との固定は磁石６２を介して行われる。また、図５に示すシャーシ６の水平な板状部分は磁石６３により磁化されるので、この板状部分については、磁力によりベゼル７と固定される。 The chassis 6 and the backlight chassis 41 are fixed through a magnet 63. The chassis 6 and the bezel 7 are fixed via a magnet 62. Further, since the horizontal plate-like portion of the chassis 6 shown in FIG. 5 is magnetized by the magnet 63, the plate-like portion is fixed to the bezel 7 by a magnetic force.
　実施の形態５ではシャーシ６に磁石を固定するようにしているので、シャーシ６を磁石で構成する場合に比べて、使用する磁石の量が少ない。そのため、シャーシ６の原価を低減することが可能となる。
　なお、シャーシ６を樹脂等で形成し、磁石６２及び６３を両面テープ、接着剤等で固定しても良い。 Since the magnets are fixed to the chassis 6 in the fifth embodiment, the amount of magnets to be used is small compared to the case where the chassis 6 is composed of magnets. Therefore, the cost of the chassis 6 can be reduced.
The chassis 6 may be formed of resin or the like, and the magnets 62 and 63 may be fixed with double-sided tape, adhesive, or the like.
（実施の形態３）
　実施の形態３では実施の形態２と同様にシャーシ６は軟磁性材料で構成する。磁石は表面に固定するのではなく、内部に埋め込む構造とする。図６は実施の形態３に係る液晶表示装置主要部の断面図である。シャーシ６の内部に磁石６４が埋め込まれている。シャーシ６は軟磁性材料で構成されている。同様に、ベゼル７及びバックライトシャーシ４１も軟磁性材料で形成してある。 (Embodiment 3)
In the third embodiment, the chassis 6 is made of a soft magnetic material as in the second embodiment. The magnet is not fixed to the surface but embedded in the interior. FIG. 6 is a cross-sectional view of the main part of the liquid crystal display device according to the third embodiment. A magnet 64 is embedded in the chassis 6. The chassis 6 is made of a soft magnetic material. Similarly, the bezel 7 and the backlight chassis 41 are also made of a soft magnetic material.
　シャーシ６は内部に埋め込まれた磁石６４により磁化される。磁化されたシャーシ６は磁気吸引力により、ベゼル７及びバックライトシャーシ４１に固定される。 The chassis 6 is magnetized by a magnet 64 embedded therein. The magnetized chassis 6 is fixed to the bezel 7 and the backlight chassis 41 by a magnetic attractive force.
　実施の形態３においても、実施の形態２と同様に、シャーシ６を磁石で構成する場合に比べて、使用する磁石の量が少ない。そのため、シャーシ６の原価を低減することが可能となる。 Also in the third embodiment, as in the second embodiment, the amount of magnets to be used is smaller than in the case where the chassis 6 is composed of magnets. Therefore, the cost of the chassis 6 can be reduced.
　各実施例で記載されている技術的特徴（構成要件）はお互いに組合せ可能であり、組み合わせすることにより、新しい技術的特徴を形成することができる。
　今回開示された実施の形態はすべての点で例示であって、制限的なものでは無いと考えられるべきである。本発明の範囲は、上記した意味では無く、特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。 The technical features (components) described in each embodiment can be combined with each other, and new technical features can be formed by combining them.
