　以下、表示装置１の備える各部材の概要について説明する。なお、表示装置１においてフロントキャビネット１０が存在する側を正面とも称し、その反対側（バックキャビネット２０が存在する側）を背面とも称する。 Hereinafter, an outline of each member included in the display device 1 will be described. In the display device 1, the side on which the front cabinet 10 is present is also referred to as the front, and the opposite side (the side on which the back cabinet 20 is present) is also referred to as the back.
　（フロントキャビネット、バックキャビネット）
　フロントキャビネット１０は、主に、表示装置１の外枠を正面側から覆う筐体である。また、バックキャビネット２０は、主に、表示装置１を背面側から覆う筐体である。 (Front cabinet, back cabinet)
The front cabinet 10 is a housing that mainly covers the outer frame of the display device 1 from the front side. The back cabinet 20 is a housing that mainly covers the display device 1 from the back side.
　フロントキャビネット１０とバックキャビネット２０との間には、フロントキャビネット１０側から順に、ベゼル１１、液晶パネル１２、シート保持枠１３、光学シート群１４、反射シート１５、ＬＥＤ基板１６、バックライトシャーシ１７、及び、メイン回路基板２１が重ねられて格納されている。 Between the front cabinet 10 and the back cabinet 20, in order from the front cabinet 10 side, the bezel 11, the liquid crystal panel 12, the sheet holding frame 13, the optical sheet group 14, the reflection sheet 15, the LED substrate 16, the backlight chassis 17, The main circuit board 21 is stored in an overlapping manner.
　（ベゼル、液晶パネル、シート保持枠）
　ベゼル１１は、液晶パネル１２の映像表示面側から液晶パネル１２の周囲を覆うように配置され、シート保持枠１３と共に液晶パネル１２を把持することにより、バックライトシャーシ１７に対する液晶パネル１２の法線方向の位置を規定する。また、ベゼル１１を設けることにより、表示装置１の強度を保つことができ、静電対策にも有効である。 (Bezel, liquid crystal panel, sheet holding frame)
The bezel 11 is disposed so as to cover the periphery of the liquid crystal panel 12 from the image display surface side of the liquid crystal panel 12, and by holding the liquid crystal panel 12 together with the sheet holding frame 13, the normal line of the liquid crystal panel 12 with respect to the backlight chassis 17. Define the position of the direction. Further, by providing the bezel 11, the strength of the display device 1 can be maintained, which is also effective for countermeasures against static electricity.
　シート保持枠１３は、液晶パネル１２を支持する部材であって、上述のようにベゼル１１と共に液晶パネル１２を把持する。また、シート保持枠１３は、後述する光学シート群１４の周囲から光が漏れることを防ぐ遮光部材である。シート保持枠１３は、バックライトシャーシ１７と共に光学シート群１４を把持することにより、バックライトシャーシ１７に対する光学シート群１４の法線方向の位置を規定する。 The sheet holding frame 13 is a member that supports the liquid crystal panel 12 and holds the liquid crystal panel 12 together with the bezel 11 as described above. The sheet holding frame 13 is a light shielding member that prevents light from leaking from the periphery of the optical sheet group 14 to be described later. The sheet holding frame 13 defines the position in the normal direction of the optical sheet group 14 with respect to the backlight chassis 17 by holding the optical sheet group 14 together with the backlight chassis 17.
　（光学シート群、反射シート）
　光学シート群１４は、後述するＬＥＤ基板１６に備えられているＬＥＤ素子１６０から出射される光の光量のムラ（すなわち輝度ムラ）を抑制するとともに、ＬＥＤ素子１６０から出射される光を調光して液晶パネル１２に向けて出射する機能を有している。 (Optical sheet group, reflective sheet)
The optical sheet group 14 suppresses unevenness in the amount of light emitted from the LED element 160 provided on the LED substrate 16 (described later) (that is, unevenness in brightness) and adjusts the light emitted from the LED element 160. And has a function of emitting light toward the liquid crystal panel 12.
　光学シート群１４は、例えば、拡散シート、プリズムシート、マイクロレンズシート、及び、拡散シートなどを含んで構成されている。なお、光学シート群１４を構成する各シートの枚数及び組み合わせは、所望の光学性能が得られるような枚数及び組み合わせであれば、特に限定されるものではない。 The optical sheet group 14 includes, for example, a diffusion sheet, a prism sheet, a microlens sheet, and a diffusion sheet. Note that the number and combination of the respective sheets constituting the optical sheet group 14 are not particularly limited as long as the number and combination can provide desired optical performance.
　反射シート１５は、ＬＥＤ素子１６０から出射される光を反射する。反射シート１５には、ＬＥＤ素子挿入孔１５１が形成されており、反射シート１５の背面側に設けられるＬＥＤ基板１６の備えるＬＥＤ素子１６０がＬＥＤ素子挿入孔１５１に挿入される。これにより、反射シート１５は、ＬＥＤ基板１６とＬＥＤ素子１６０との間に位置することになる。 The reflection sheet 15 reflects the light emitted from the LED element 160. An LED element insertion hole 151 is formed in the reflection sheet 15, and the LED element 160 included in the LED substrate 16 provided on the back side of the reflection sheet 15 is inserted into the LED element insertion hole 151. Thereby, the reflective sheet 15 is positioned between the LED substrate 16 and the LED element 160.
　反射シート１５は、ＬＥＤ基板１６及びバックキャビネット２０などに吸収されていた、ＬＥＤ素子１６０から出射される光を反射して有効に利用できるため、光学シート群１４に向けて出射される光量を増やすことができる。これによって、反射シート１５は、液晶パネル１２の輝度を向上させる事が出来る。 Since the reflection sheet 15 reflects the light emitted from the LED element 160 that has been absorbed by the LED substrate 16 and the back cabinet 20 and can be used effectively, the amount of light emitted toward the optical sheet group 14 is increased. be able to. Thereby, the reflection sheet 15 can improve the luminance of the liquid crystal panel 12.
　なお、反射シート１５は、入射した光が正反射するシートであってもよいが、乱反射するシートを用いることがより好ましい。反射シート１５として入射した光が乱反射するシートを用いることによって、反射シート１５は、入射角と異なる角度の反射成分を含んで光を反射させることができる。 The reflective sheet 15 may be a sheet that regularly reflects incident light, but it is more preferable to use a sheet that irregularly reflects light.

　（ＬＥＤ基板１６及びバックライトシャーシ１７の特有の構造について）
　本実施形態では、ＬＥＤ基板１６及びバックライトシャーシ１７は、ビス留めを必要とすることなくＬＥＤ基板１６をバックライトシャーシ１７に固定するための特有の構造を有している。 (Regarding the unique structure of the LED board 16 and the backlight chassis 17)
In the present embodiment, the LED board 16 and the backlight chassis 17 have a specific structure for fixing the LED board 16 to the backlight chassis 17 without requiring screwing.
　バックライトシャーシ１７及びＬＥＤ基板１６が有する特有の構造について、図１及び図４を参照しながら詳細に説明する。 The specific structure of the backlight chassis 17 and the LED substrate 16 will be described in detail with reference to FIGS.
　図１は、バックライトシャーシ１７及びＬＥＤ基板１６の正面図である。また、図４は、バックライトシャーシ１７の部分拡大図（図１において破線で囲まれている部分の拡大図）である。 FIG. 1 is a front view of the backlight chassis 17 and the LED board 16. 4 is a partially enlarged view of the backlight chassis 17 (an enlarged view of a portion surrounded by a broken line in FIG. 1).
　図１からわかるように、ＬＥＤ基板１６は、バックライトシャーシ１７への取り付けに適した規定のサイズの基板である。即ち、ＬＥＤ基板１６は、規定の厚みを有しており、バックライトシャーシ１７への取り付けが完了した時に、バックライトシャーシ１７に形成されているある平面（バックライトシャーシ１７の前方方向を法線方向とする平面Ｑ）と面一になるようになっている。また、ＬＥＤ基板１６には、その長手方向に沿って複数（本実施形態では、５個）の切欠き１６２が形成されている。 As can be seen from FIG. 1, the LED board 16 is a board having a specified size suitable for attachment to the backlight chassis 17. That is, the LED board 16 has a specified thickness, and when the attachment to the backlight chassis 17 is completed, a certain plane formed on the backlight chassis 17 (the front direction of the backlight chassis 17 is normal). It is designed to be flush with the plane Q). In addition, a plurality of (five in this embodiment) notches 162 are formed in the LED substrate 16 along the longitudinal direction thereof.
　また、図１からわかるように、バックライトシャーシ１７には、複数（本実施形態では２０個）の突起部１７３がマトリクス状に（本実施形態では、４行５列を成すように）形成されている。 Further, as can be seen from FIG. 1, the backlight chassis 17 is formed with a plurality of (in this embodiment, 20) protrusions 173 in a matrix (in this embodiment, 4 rows and 5 columns). ing.
　図１からわかるように、突起部１７３と切欠き１６２とは、互いに嵌合可能な形状になっており、各行の５つの突起部１７３は、ＬＥＤ基板１６の５つの切欠き１６２と同時に嵌合可能な位置に形成されている。即ち、図１におけるＸ軸負方向側からｉ番目の切欠き１６２とｉ＋１番目の切欠き１６２との間の距離は、各行におけるＸ軸負方向側からｉ番目の突起部１７３とｉ＋１番目の突起部１７３との間の距離と略等しくなっている。 As can be seen from FIG. 1, the protrusions 173 and the notches 162 have shapes that can be fitted to each other, and the five protrusions 173 in each row are simultaneously fitted with the five notches 162 of the LED board 16. It is formed in a possible position. That is, the distance between the i-th notch 162 and the i + 1-th notch 162 from the X-axis negative direction side in FIG. 1 is the i-th protrusion 173 and the i + 1-th protrusion from the X-axis negative direction side in each row. The distance to the portion 173 is substantially equal.
　また、図１からわかるように、複数（本実施形態では２０個）のツメ部１７２がマトリクス状に（本実施形態では、４行５列を成すように）形成されており、複数の出っ張り部１７４がマトリクス状に（本実施形態では、４行６列を成すように）形成されている。 Further, as can be seen from FIG. 1, a plurality of (in this embodiment, 20) claw portions 172 are formed in a matrix (in this embodiment, 4 rows and 5 columns), and a plurality of protruding portions are formed. 174 are formed in a matrix (in this embodiment, 4 rows and 6 columns).
　以下、更に図５～図７を参照しながら、バックライトシャーシ１７が有する特有の構造（特に、ツメ部１７２、突起部１７３および出っ張り部１７４）の詳細について説明する。 Hereinafter, with reference to FIGS. 5 to 7, details of the specific structure (particularly, the claw portion 172, the projection portion 173, and the protruding portion 174) of the backlight chassis 17 will be described.
　図５は、バックライトシャーシ１７が有する特有の構造（図４において破線で囲まれている部分の構造）を、斜視図およびＡ－Ａ’線断面図として示した図である。また、図６はバックライトシャーシ１７のＢ－Ｂ’線切断部断面図であり、図７は、バックライトシャーシ１７のＣ－Ｃ’線切断部断面図である。なお、Ａ－Ａ’線、Ｂ－Ｂ’線、及び、Ｃ－Ｃ’線は、図４に示されている。 FIG. 5 is a perspective view and a cross-sectional view taken along the line A-A ′ of a specific structure (a structure surrounded by a broken line in FIG. 4) that the backlight chassis 17 has. 6 is a cross-sectional view taken along the line B-B ′ of the backlight chassis 17, and FIG. 7 is a cross-sectional view taken along the line C-C ′ of the backlight chassis 17. The A-A ′ line, the B-B ′ line, and the C-C ′ line are shown in FIG.
　ツメ部１７２は一定の復元力を有し、ツメ部１７２と平面Ｐとの間のＺ軸方向の距離は、ＬＥＤ基板１６の厚さよりも少し短くなっている。即ち、図５の（ａ）及び（ｂ）に示したツメ部１７２の形状からもわかるように、ツメ部１７２は、ＬＥＤ基板１６を、その主面（即ち、ＬＥＤ素子１６０が配置される部品面）を押圧することで挟持できるようになっている。また、図５の（ｂ）及び図６からわかるように、ツメ部１７２の根元部１７２ｒの厚み（Ｚ軸方向の外寸の長さ）は、ツメ部１７２の先端部１７２ｔの厚み（Ｚ軸方向の外寸の長さ）よりも厚くなっている。なお、ツメ部１７２をこのように構成する理由は、ＬＥＤ基板１６をしっかり挟持し続けることができるようにツメ部１７２の剛性を高めるためである。また、本実施形態では、根元部１７２ｒのＺ軸方向の外寸の長さを先端部１７２ｔのＺ軸方向の外寸の長さをよりも長くするために根元部１７２を曲げ加工（絞り加工）により形成している。このため、根元部１７２ｒの材料の厚み（Ｚ軸方向の長さ）と先端部１７２ｔの材料の厚み（Ｚ軸方向の長さ）とが略等しくなっている。 The claw portion 172 has a certain restoring force, and the distance in the Z-axis direction between the claw portion 172 and the plane P is slightly shorter than the thickness of the LED substrate 16. That is, as can be seen from the shape of the claw portion 172 shown in FIGS. 5A and 5B, the claw portion 172 has the LED substrate 16 on its main surface (that is, the component on which the LED element 160 is disposed). Can be clamped by pressing the surface. Further, as can be seen from FIG. 5B and FIG. 6, the thickness of the base portion 172r of the claw portion 172 (the length of the outer dimension in the Z-axis direction) is the thickness of the tip portion 172t of the claw portion 172 (Z-axis). It is thicker than the length of the outer dimension in the direction). The reason for configuring the claw portion 172 in this way is to increase the rigidity of the claw portion 172 so that the LED substrate 16 can be firmly held. In the present embodiment, the root portion 172 is bent (drawing) so that the outer dimension of the root portion 172r in the Z-axis direction is longer than the outer dimension of the tip portion 172t in the Z-axis direction. ). For this reason, the thickness of the material of the root portion 172r (length in the Z-axis direction) and the thickness of the material of the tip portion 172t (length in the Z-axis direction) are substantially equal.
　また、図５および図７からわかるように、出っ張り部１７４は、その先端部分が、バックライトシャーシ１７の下方方向（Ｙ軸正方向）を法線方向とする面（以下「先端面」と称する）を成している。また、出っ張り部１７４は、先端面とは別の面（バックライトシャーシ１７の前方方向（Ｚ軸正方向）を法線方向とする平面、以下、「出っ張り部１７４の側面」と称する）を有しており、出っ張り部１７４の当該平面は、平面Ｑと面一になっている。 Further, as can be seen from FIGS. 5 and 7, the protruding portion 174 has a front end portion whose surface is normal to the downward direction (Y-axis positive direction) of the backlight chassis 17 (hereinafter referred to as “front end surface”). ). Further, the protruding portion 174 has a surface different from the front end surface (a plane whose normal direction is the front direction (Z-axis positive direction) of the backlight chassis 17, hereinafter referred to as “side surface of the protruding portion 174”). The plane of the protruding portion 174 is flush with the plane Q.
　また、図１からわかるように、ツメ部１７２と出っ張り部１７４とは、Ｘ軸方向の位置が互いに異なるように配置されている。より具体的には、ツメ部１７２と出っ張り部１７４とがＸ軸方向に沿って交互に配置されている。このような構成とすることで、ＬＥＤ基板１６を所定の位置に固定することが容易になる。 Further, as can be seen from FIG. 1, the claw portion 172 and the protruding portion 174 are arranged so that the positions in the X-axis direction are different from each other. More specifically, the claw portions 172 and the protruding portions 174 are alternately arranged along the X-axis direction. With such a configuration, it becomes easy to fix the LED substrate 16 at a predetermined position.
　即ち、切欠き１６３が形成されている箇所におけるＬＥＤ基板１６のＹ軸方向の幅の長さは、ツメ部１７２の根元と出っ張り部１７４の先端面との間のＹ軸方向の距離に等しい長さであるが、仮にツメ部１７２と出っ張り部１７４とをＸ軸方向の位置が同じになるように配置した場合、作業者がＬＥＤ基板１６をツメ部１７２に挟持させる作業を行う際に、出っ張り部１７４の存在が作業の妨げとなってしまう。 That is, the length of the width in the Y-axis direction of the LED substrate 16 at the portion where the notch 163 is formed is equal to the distance in the Y-axis direction between the root of the claw portion 172 and the tip surface of the protruding portion 174. However, if the claw portion 172 and the protruding portion 174 are arranged so that the positions in the X-axis direction are the same, the protruding portion is used when the operator performs the work of holding the LED board 16 between the claw portions 172. The presence of the portion 174 hinders work.
　本実施形態では、ツメ部１７２と出っ張り部１７４とが、Ｘ軸方向の位置が互いに異なるように配置されているため、ＬＥＤ基板１６をツメ部１７２に挟持させる作業を行う際に出っ張り部１７４の存在が作業の妨げにはならず、ＬＥＤ基板１６のＺ軸方向の撓みを利用しつつ、好適にＬＥＤ基板１６をツメ部１７２に挿入することができる。 In the present embodiment, since the claw portion 172 and the protruding portion 174 are arranged so that the positions in the X-axis direction are different from each other, the work of holding the LED board 16 between the claw portions 172 is performed. The presence does not hinder the work, and the LED board 16 can be suitably inserted into the claw portion 172 while utilizing the bending of the LED board 16 in the Z-axis direction.
　また、より具体的には、ツメ部１７２と出っ張り部１７４とが交互に配置されているため、作業者は、出っ張り部１７４の先端面にＬＥＤ基板１６の側面（切欠き１６２がない側面）を当接させた後に、簡単に次のツメ部１７２にＬＥＤ基板１６を挟持させることができる。 More specifically, since the claw portions 172 and the protruding portions 174 are alternately arranged, the operator places the side surface of the LED substrate 16 (the side surface without the notch 162) on the tip surface of the protruding portion 174. After the contact, the LED board 16 can be easily held by the next claw portion 172.
　また、図５および図７からわかるように、突起部１７３の高さ（平面Ｐから突起部１７３の先端までの長さ（Ｚ軸方向の長さ））は、出っ張り部１７４の厚さ（即ち、Ｚ軸方向の長さ）と同じ長さになっている。 Further, as can be seen from FIGS. 5 and 7, the height of the protrusion 173 (the length from the plane P to the tip of the protrusion 173 (the length in the Z-axis direction)) is the thickness of the protruding portion 174 (that is, , The length in the Z-axis direction).
　また、ツメ部１７２の高さ（平面Ｐからツメ部１７２への最長のＺ軸方向の長さ）はＬＥＤ素子１６０のレンズ球面部の高さ（平面Ｐからレンズ球面部への最長のＺ軸方向の長さ）よりも低く形成されている。このような構造にすることによって、ツメ部１７２がレンズより照射された光を遮ることがなくなり、ＬＥＤ素子１６０からの光がツメ部１７２の影響を受けなくなり、輝度ムラが生じにくくなっている。 The height of the claw portion 172 (the longest length in the Z-axis direction from the plane P to the claw portion 172) is the height of the lens spherical portion of the LED element 160 (the longest Z-axis from the plane P to the lens spherical portion). (Length in the direction). With such a structure, the claw portion 172 does not block the light emitted from the lens, the light from the LED element 160 is not affected by the claw portion 172, and luminance unevenness is less likely to occur.
　また、平面ＰはＬＥＤ基板１６を固定する為に設けられたＸ軸方向に沿った絞り加工に加えて、Ｙ軸方向の絞り加工もなされている。このようにＸ軸方向の絞り加工とＹ軸方向の絞り加工を組み合わせることによってＸ軸方向Ｙ軸方向の何れの方向に沿っても撓みづらく、強度が向上する。 In addition to the drawing process along the X-axis direction provided for fixing the LED substrate 16, the plane P is also drawn in the Y-axis direction. Thus, by combining the drawing in the X-axis direction and the drawing in the Y-axis direction, it is difficult to bend along any direction of the X-axis direction and the Y-axis direction, and the strength is improved.
　以上、バックライトシャーシ１７及びＬＥＤ基板１６が有する特有の構造について説明した。 The specific structure of the backlight chassis 17 and the LED substrate 16 has been described above.
　（ＬＥＤ基板１６のバックライトシャーシ１７への取り付け方の詳細）
　以下、ＬＥＤ基板１６のバックライトシャーシ１７への取り付け方の詳細について、更に図８～図１２を参照しながら説明する。 (Details of how to attach the LED board 16 to the backlight chassis 17)
Hereinafter, details of how to attach the LED board 16 to the backlight chassis 17 will be described with reference to FIGS.
　図９は、ＬＥＤ基板１６の切欠き１６２をバックライトシャーシ１７の突起部１７３（嵌合部）に嵌合させる様子を示した図である。図１０は、切欠き１６２が突起部１７３に嵌合した結果、ＬＥＤ基板１６の側面がバックライトシャーシ１７の出っ張り部１７４の先端面（当接部）に当接する様子を示した図である。図１１は、取り付けるべき全てのＬＥＤ基板１６（即ち、４つのＬＥＤ基板１６）が取り付けられた状態のバックライトシャーシ１７を斜視図及び正面図として示した図である。図１２は、バックライトシャーシ１７に取り付けられた状態のＬＥＤ基板１６とＬＥＤ基板１６を固定している上述の特有の構造とを、斜視図およびＡ－Ａ’線断面図として示した図である。 FIG. 9 is a view showing a state in which the notch 162 of the LED substrate 16 is fitted into the protrusion 173 (fitting portion) of the backlight chassis 17. FIG. 10 is a diagram illustrating a state in which the side surface of the LED board 16 comes into contact with the distal end surface (contact portion) of the protruding portion 174 of the backlight chassis 17 as a result of the notch 162 being fitted into the protrusion 173. FIG. 11 is a perspective view and a front view of the backlight chassis 17 in a state where all the LED boards 16 to be attached (that is, four LED boards 16) are attached. FIG. 12 is a perspective view and a cross-sectional view taken along the line AA ′ of the LED board 16 attached to the backlight chassis 17 and the above-described unique structure fixing the LED board 16. .
　ＬＥＤ基板１６のバックライトシャーシ１７への取り付ける工程は、以下の２つの工程から構成される。 The process of attaching the LED board 16 to the backlight chassis 17 includes the following two processes.
　工程１）ツメ部１７２にＬＥＤ基板１６を当該ＬＥＤ基板１６の主面を押圧することで挟持させる工程
　工程２）突起部１７３（嵌合部）を切欠き１６２にしっかり嵌合させ、出っ張り部１７４の先端面（当接部）を、ＬＥＤ基板１６の側面（切欠き１６２が形成されている側面に対向する側面）に当接させる工程
　工程１において、作業者は、ツメ部１７２にＬＥＤ基板１６を挟持させるために、図８に示すように、ＬＥＤ基板１６を、ツメ部１７２と平面Ｐとの間に挟み込む。その結果、弾性変形したツメ部１７２は、その復元力により、ＬＥＤ基板１６を挟持する。 Step 1) Step of clamping the LED substrate 16 to the claw portion 172 by pressing the main surface of the LED substrate 16 Step 2) The protrusion 173 (fitting portion) is firmly fitted into the notch 162, and the protruding portion 174 is formed. The front end surface (contact portion) of the LED substrate 16 is brought into contact with the side surface of the LED substrate 16 (the side surface opposite to the side surface on which the notch 162 is formed). As shown in FIG. 8, the LED substrate 16 is sandwiched between the claw portion 172 and the plane P. As a result, the elastically deformed claw portion 172 sandwiches the LED board 16 by its restoring force.
　工程２において、作業者は、図９に示すように、ＬＥＤ基板１６をツメ部１７２に挟持させたまま、切欠き１６２が突起部１７３に嵌合するようにＬＥＤ基板１６を動かし、更に、ＬＥＤ基板１６を平面Ｐ側に押し込む。その結果、図１０に示すように、切欠き１６２は突起部１７３にしっかり嵌合し、出っ張り部１７４の先端面はＬＥＤ基板１６の側面に当接する。 In step 2, as shown in FIG. 9, the operator moves the LED board 16 so that the notch 162 fits into the protrusion 173 while holding the LED board 16 between the claw parts 172, and further, The substrate 16 is pushed into the plane P side. As a result, as shown in FIG. 10, the notch 162 is firmly fitted to the protruding portion 173, and the tip end surface of the protruding portion 174 contacts the side surface of the LED substrate 16.
　４つのＬＥＤ基板１６の全てが取り付けられたバックライトシャーシ１７を図１１に示し、その一部分（図１１において破線で囲まれている部分）の拡大図を図１２に示す。 FIG. 11 shows the backlight chassis 17 to which all four LED boards 16 are attached, and FIG. 12 shows an enlarged view of a part thereof (a part surrounded by a broken line in FIG. 11).
　図１２に示すように、ＬＥＤ基板１６が取り付けられたバックライトシャーシ１７では、「出っ張り部１７４の側面」「平面Ｑ」および「ＬＥＤ基板１６の主面」が反射シート１５に接触するが、これらの面は互いに面一になっている。従って、バックライトシャーシ１７は、表示装置１の内部で反射シート１５を歪めてしまわないような構造を有していると言える。 As shown in FIG. 12, in the backlight chassis 17 to which the LED substrate 16 is attached, the “side surface of the protruding portion 174”, “plane Q”, and “main surface of the LED substrate 16” are in contact with the reflection sheet 15. The planes are flush with each other. Therefore, it can be said that the backlight chassis 17 has a structure that does not distort the reflective sheet 15 inside the display device 1.
　また、バックライトシャーシ１７におけるＬＥＤ基板１６を固定するための構造は絞り加工（曲げ加工）により形成されているため、当該構造は、バックライトシャーシ１７の強度の向上に寄与していると言える。 Further, since the structure for fixing the LED substrate 16 in the backlight chassis 17 is formed by drawing (bending), it can be said that the structure contributes to the improvement of the strength of the backlight chassis 17.
　なお、作業者は、ＬＥＤ基板１６をバックライトシャーシ１７に取り付けた後、公知の方法で、キャビネット（フロントキャビネット１０及びバックキャビネット２０）の内部に各種パーツを組み込むことにより、図１３に示すような外観の表示装置１を製造できる。 The worker attaches the LED board 16 to the backlight chassis 17 and then incorporates various parts into the cabinet (the front cabinet 10 and the back cabinet 20) by a known method, as shown in FIG. The external display device 1 can be manufactured.
　（バックライトシャーシ１７の利点）
　以上の説明から以下のことが言える。 (Advantages of the backlight chassis 17)
The following can be said from the above description.
　即ち、バックライトシャーシ１７は、ＬＥＤ基板１６が取り付けられるシャーシである。 That is, the backlight chassis 17 is a chassis to which the LED board 16 is attached.
　バックライトシャーシ１７は、ＬＥＤ基板１６をＬＥＤ基板１６の主面を押圧することで挟持するツメ部１７２と、ＬＥＤ基板１６のある側面に形成された切欠き１６２に対し、ツメ部１７２がＬＥＤ基板１６を挟持している状態において嵌合可能な位置にある突起部１７３と、突起部１７３が切欠き１６２に嵌合している状態において、ＬＥＤ基板１６における、上記ある側面に対向する別の側面に当接する出っ張り部１７４と、を備えている。 The backlight chassis 17 has a claw portion 172 that holds the LED substrate 16 by pressing the main surface of the LED substrate 16 and a notch 162 formed on a side surface of the LED substrate 16. In the state which can be fitted in the state which has pinched | interposed 16, another side surface which opposes the said side surface in the LED board 16 in the state which the projection part 173 is fitting in the notch 162 And a protruding portion 174 that comes into contact with.
　上記の構成によれば、バックライトシャーシ１７のツメ部１７２は、ＬＥＤ基板１６の主面を押圧することでＬＥＤ基板１６を挟持するので、バックライトシャーシ１７は、意図せずＬＥＤ基板１６が主面の法線方向にずれることを防ぐことができる。 According to the above configuration, the claw portion 172 of the backlight chassis 17 holds the LED board 16 by pressing the main surface of the LED board 16, so the backlight chassis 17 is not intended and the LED board 16 is mainly used. It is possible to prevent displacement in the normal direction of the surface.
　また、上記の構成によれば、バックライトシャーシ１７の突起部１７３は、ＬＥＤ基板１６のある側面に形成された切欠き１６２に嵌合するので、バックライトシャーシ１７は、意図せずＬＥＤ基板１６が抜出方向（嵌合方向とは反対の方向）以外の方向にずれることを防ぐことができる。 Moreover, according to said structure, since the projection part 173 of the backlight chassis 17 fits into the notch 162 formed in the side with the LED board 16, the backlight chassis 17 unintentionally LED board 16 Can be prevented from shifting in a direction other than the pulling-out direction (the direction opposite to the fitting direction).
　さらに、上記の構成によれば、バックライトシャーシ１７の出っ張り部１７４は、ＬＥＤ基板１６の別の側面（切欠き１６２が形成された側面に対向する側面）に当接するので、バックライトシャーシ１７は、意図せずＬＥＤ基板１６が抜出方向にずれることを防ぐことができる。 Furthermore, according to the above configuration, the protruding portion 174 of the backlight chassis 17 abuts on another side surface of the LED substrate 16 (a side surface facing the side surface on which the notch 162 is formed). The LED substrate 16 can be prevented from being unintentionally displaced in the extraction direction.
　従って、バックライトシャーシ１７は、ビス留めを必要とすることなく、しっかりとＬＥＤ基板１６を固定できるような構造を有していると言える。 Therefore, it can be said that the backlight chassis 17 has a structure that allows the LED substrate 16 to be firmly fixed without requiring screwing.
　よって、バックライトシャーシ１７には、従来よりも手間をかけずに（即ち、ビス留め作業を行うことなく）ＬＥＤ基板１６を取り付けることができる、という利点があると言える。 Therefore, it can be said that the backlight chassis 17 has an advantage that the LED substrate 16 can be attached with less effort than before (that is, without screwing).
　また、バックライトシャーシ１７は、ＬＥＤ基板１６に当接するため、ＬＥＤ基板１６に発生した熱をＬＥＤ基板１６から逃がす放熱板としての役割も担うことになる。従って、バックライトシャーシ１７には、バックライトシャーシ１７とは別個に放熱板を用意することを不要にする（即ち、表示装置のコスト削減に寄与する）、という利点もある。 Further, since the backlight chassis 17 abuts on the LED board 16, the backlight chassis 17 also serves as a heat radiating plate that releases heat generated in the LED board 16 from the LED board 16. Therefore, the backlight chassis 17 has an advantage that it is not necessary to prepare a heat sink separately from the backlight chassis 17 (that is, it contributes to cost reduction of the display device).

　〔実施形態５〕
　本発明に係る表示装置の更に別の一実施形態について図１４を参照しながら説明する。 [Embodiment 5]
Another embodiment of the display device according to the present invention will be described with reference to FIG.
　図１４は、本実施形態に係るバックライトシャーシのツメ部にＬＥＤ基板を挟持させる様子を示した図である。 FIG. 14 is a diagram showing a state in which the LED substrate is held between the tabs of the backlight chassis according to the present embodiment.
　〔表示装置の構成の概要〕
　本実施形態に係る表示装置は、ＬＥＤ基板１６をしっかり挟持し続けることができるようにツメ部１７２の剛性が高められている点において、実施形態１、２、３に係る表示装置と類似しているが、ＬＥＤ基板１６が抜出方向（Ｙ軸負方向）以外の方向にずれることを防ぐために形成される、バックライトシャーシ１７の側面の切欠きがどのように構成されたかという点において実施形態１、２、３に係る表示装置と異なっている。 [Overview of display device configuration]
The display device according to the present embodiment is similar to the display devices according to Embodiments 1, 2, and 3 in that the rigidity of the claw portion 172 is increased so that the LED substrate 16 can be securely held. However, in terms of how the notch on the side surface of the backlight chassis 17 formed to prevent the LED substrate 16 from shifting in a direction other than the extraction direction (Y-axis negative direction) is configured. This is different from the display devices according to 1, 2, and 3.
　本実施形態に関わる表示装置は図１４の様に、ＬＥＤ基板１６のある側面に切欠き１６３が形成されている。切欠き１６３はＬＥＤ基板１６の主面を挟持するツメ部１７２の根元のＸ軸方向の幅と略同じ幅になるように形成されており、ツメ部１７２の根元と切欠き１６３の底とが最も近づいた状態を保つようにツメ部１７２がＬＥＤ基板１６を挟持している。 In the display device according to the present embodiment, a notch 163 is formed on a side surface of the LED substrate 16 as shown in FIG. The notch 163 is formed to have a width substantially the same as the width in the X-axis direction of the base of the claw part 172 that sandwiches the main surface of the LED substrate 16, and the base of the claw part 172 and the bottom of the notch 163 are formed. The claw portion 172 sandwiches the LED board 16 so as to keep the closest state.
　なお、ツメ部１７２の根元のＸ軸方向の幅は切欠き１６３の幅と略同じ幅であるので、ツメ部１７２の根元のＸ軸方向の幅は、ツメ部１７２の根元と切欠き１６３の底とが最も近づいた状態を保つようにツメ部１７２がＬＥＤ基板１６を挟持している時に切欠き１６３の２つの側部が同時にツメ部１７２の根元に接するような長さの幅である、とも言える。 Since the width of the claw portion 172 in the X-axis direction is substantially the same as the width of the notch 163, the width of the claw portion 172 in the X-axis direction is the same as that of the claw portion 172 and the notch 163. The width is such that the two side portions of the notch 163 are in contact with the base of the claw portion 172 at the same time when the claw portion 172 holds the LED board 16 so as to keep the state closest to the bottom. It can also be said.
　この構成により、バックライトシャーシ１７は、意図せずＬＥＤ基板１６が抜出方向以外の方向にずれることを防ぐことができる。またこの構成により、ツメ部１７２の周辺の孔がＬＥＤ基板１６によって塞がれる。このような構造とすることで、ＬＥＤ基板１６をツメ部１７２に対して装着完了した状態において、ＬＥＤ素子１６０の光がツメ部１７２の周辺の孔からバックライトシャーシ１７の背面側に漏れることがなくなり、無用な光漏れを防ぐことができる。 With this configuration, the backlight chassis 17 can prevent the LED substrate 16 from being unintentionally displaced in a direction other than the extraction direction. Further, with this configuration, the hole around the claw portion 172 is closed by the LED substrate 16. With such a structure, the light of the LED element 160 may leak from the hole around the claw part 172 to the back side of the backlight chassis 17 in a state where the LED substrate 16 is completely attached to the claw part 172. This eliminates unnecessary light leakage.
　（ＬＥＤ基板１６のバックライトシャーシ１７への取り付け方）
　ＬＥＤ基板１６のバックライトシャーシ１７への取り付ける工程は、以下の２つの工程から構成される。 (How to attach the LED board 16 to the backlight chassis 17)
The process of attaching the LED board 16 to the backlight chassis 17 includes the following two processes.
　工程１）ツメ部１７２の根元に切欠き１６３の底とが最も近づいた状態を保つように、当該ＬＥＤ基板１６の主面を押圧することで挟持させる工程
　工程２）出っ張り部１７４の先端面（当接部）を、ＬＥＤ基板１６の側面（切欠き１６２が形成されている側面に対向する側面）に当接させる工程
　工程１において、作業者は、ツメ部１７２にＬＥＤ基板１６を挟持させるために、ＬＥＤ基板１６を、ツメ部１７２と平面Ｐとの間に挟み込む。その結果、弾性変形したツメ部１７２は、その復元力により、ＬＥＤ基板１６を挟持する。 Step 1) Step of pressing the main surface of the LED board 16 so as to keep the bottom of the notch 163 closest to the root of the claw portion 172 Step 2) The front end surface of the protruding portion 174 ( The step of bringing the abutting portion into contact with the side surface of the LED substrate 16 (the side surface facing the side surface on which the notch 162 is formed) In step 1, the operator holds the LED substrate 16 on the claw portion 172. Then, the LED substrate 16 is sandwiched between the claw portion 172 and the plane P. As a result, the elastically deformed claw portion 172 sandwiches the LED board 16 by its restoring force.
　工程２において、作業者は、ＬＥＤ基板１６をツメ部１７２に挟持させたまま、ＬＥＤ基板１６を平面Ｐ側に押し込む。その結果、出っ張り部１７４の先端面はＬＥＤ基板１６の側面に当接する。 In step 2, the operator pushes the LED board 16 toward the plane P side while holding the LED board 16 between the claw portions 172. As a result, the tip end surface of the protruding portion 174 contacts the side surface of the LED substrate 16.
　なお、作業者は、ＬＥＤ基板１６をバックライトシャーシ１７に取り付けた後、公知の方法で、キャビネット（フロントキャビネット１０及びバックキャビネット２０）の内部に各種パーツを組み込むことにより、図１３に示すような外観の表示装置１を製造できる。 The worker attaches the LED board 16 to the backlight chassis 17 and then incorporates various parts into the cabinet (the front cabinet 10 and the back cabinet 20) by a known method, as shown in FIG. The external display device 1 can be manufactured.
　〔実施形態６〕
　本発明に係る表示装置の更に別の一実施形態について図１５及び図１６を参照しながら説明する。 [Embodiment 6]
Another embodiment of the display device according to the present invention will be described with reference to FIGS.
　図１５は、本実施形態に係るバックライトシャーシ１７の開口部にＬＥＤ基板１６の２つの切欠きの間にある凸部を挿入させる様子を示した図である。図１６（ｂ）は、バックライトシャーシ１７のＥ－Ｅ’線切断部断面図である。なお、Ｅ－Ｅ’線は、図１６（ａ）に示されている。 FIG. 15 is a diagram illustrating a state in which a convex portion between two notches of the LED substrate 16 is inserted into the opening portion of the backlight chassis 17 according to the present embodiment. FIG. 16B is a cross-sectional view taken along line E-E ′ of the backlight chassis 17. The E-E ′ line is shown in FIG.
　本実施形態に関わる表示装置は図１５の様に、ＬＥＤ基板１６のある側面に２つの切欠きが形成されている。２つの切欠きは連続して設けられおり、２つの切欠きの間に凸部１６４が形成されている。 The display device according to this embodiment has two notches formed on a side surface of the LED substrate 16 as shown in FIG. The two notches are provided continuously, and a convex portion 164 is formed between the two notches.
　また、図１６の（ａ）からわかるように、バックライトシャージ１７の平面Ｐ（ある面）には挿入部１７２ｂが形成されている。挿入部１７２ｂは、２つの連続する切欠きの間の凸部１６４が挿入される部分である。 Further, as can be seen from FIG. 16A, an insertion portion 172b is formed on the plane P (a certain surface) of the backlight shale 17. The insertion part 172b is a part into which the convex part 164 between two continuous notches is inserted.
　図１６の（ｂ）に示すように、挿入部１７２ｂは、平面Ｐを貫く開口部と、この開口部から見て平面Ｐに垂直な方向に立ち上がったうえで平面Ｐに対して平行に延びる突起部１７２ｃとを有している。このように、挿入部１７２ｂは、トンネルの入り口の様な形状を有している。このような形状とすることによって、ＬＥＤ基板１６と挿入部１７２ｂとの接触面積を好適に確保することができ、Ｚ軸方向の支持力を十分に提供することができる。なお、本実施形態では、突起部１７２ｃがＹ軸方向負側に延びているが、突起部１７２ｃはそのような構成には限定されない。 As shown in FIG. 16B, the insertion portion 172b includes an opening that penetrates the plane P, and a protrusion that rises in a direction perpendicular to the plane P as viewed from the opening and extends parallel to the plane P. Part 172c. Thus, the insertion part 172b has a shape like the entrance of a tunnel. By setting it as such a shape, the contact area of the LED board 16 and the insertion part 172b can be ensured suitably, and the support force of a Z-axis direction can fully be provided. In the present embodiment, the protrusion 172c extends to the Y axis direction negative side, but the protrusion 172c is not limited to such a configuration.
　開口部および突起部１７２ｃの形状はＬＥＤ基板１６が抜出方向以外の方向（Ｘ軸方向）にずれることを防ぐ事ができる形状であればよく、この様な構成であれば例えば、平面Ｐに垂直な方向（Ｚ軸正方向）から見た開口部および突起部１７２ｃの形状は、矩形、台形等でもよい。 The shape of the opening and the protrusion 172c may be any shape that can prevent the LED substrate 16 from shifting in a direction other than the extraction direction (X-axis direction). The shape of the opening and the protrusion 172c viewed from the vertical direction (Z-axis positive direction) may be a rectangle, a trapezoid, or the like.
　本実施形態では、開口部および突起部１７２ｃの形状は台形であり、突起部１７２ｃの先端の幅（開口部のＹ軸負方向端部におけるＸ軸方向の幅）を凸部１６４のＸ軸方向の幅と同一とし、突起部１７２ｃの根元の幅（開口部のＹ軸正方向端部におけるＸ軸方向の幅）を、２つの切欠きのうちの一方の切欠きの幅の長さと他方の切欠きの幅の長さと凸部１６４の幅の長さとの和と略同一とする。 In this embodiment, the shape of the opening and the protrusion 172c is a trapezoid, and the width of the tip of the protrusion 172c (the width in the X-axis direction at the Y-axis negative direction end of the opening) is the X-axis direction of the protrusion 164. The width of the base of the protrusion 172c (the width in the X-axis direction at the Y-axis positive end of the opening) is set to the length of one of the two notches and the other It is substantially the same as the sum of the width of the notch and the width of the protrusion 164.
　なお、突起部１７２ｃの根元の幅は２つの切欠きのうちの一方の切欠きの幅の長さと他方の切欠きの幅の長さと凸部１６４の幅の長さとの和と略同一であるので、突起部１７２ｃの根元の幅は、凸部１６４が開口部にしっかり（根元まで）挿入された状態において２つの切欠きの各々の「凸部１６４に対向する側部」が同時にツメ部１７２の根元に接するような長さの幅である、とも言える。 The base width of the protrusion 172c is substantially the same as the sum of the width of one of the two cutouts, the width of the other cutout, and the width of the convex portion 164. Therefore, the width of the base of the protrusion 172c is such that the “side facing the protrusion 164” of each of the two notches is the claw 172 at the same time when the protrusion 164 is firmly inserted into the opening (up to the root). It can also be said that it is the width of the length that touches the root of the.
　図１５を見るとわかるように、このように開口部および突起部１７２ｃが形成されていれば、凸部１６４が開口部にしっかり（根元まで）挿入された状態のＬＥＤ基板１６は、意図せず抜出方向以外の方向にずれることはない。 As can be seen from FIG. 15, if the opening and the protrusion 172c are formed in this way, the LED substrate 16 in a state where the convex portion 164 is firmly inserted into the opening (up to the root) is not intended. There is no deviation in the direction other than the extraction direction.
　また、開口部に凸部１６４をしっかり挿入することにより、開口部がＬＥＤ基板１６によって塞がれる。これにより、ＬＥＤ素子１６０が発した光が開口部から背面側に漏れることがなくなり、無用な光漏れを防ぐことができる。 In addition, by firmly inserting the protrusion 164 into the opening, the opening is blocked by the LED substrate 16. Thereby, the light emitted from the LED element 160 does not leak from the opening to the back side, and unnecessary light leakage can be prevented.
　（ＬＥＤ基板１６のバックライトシャーシ１７への取り付け方）
　ＬＥＤ基板１６のバックライトシャーシ１７への取り付ける工程は、以下の２つの工程から構成される。 (How to attach the LED board 16 to the backlight chassis 17)
The process of attaching the LED board 16 to the backlight chassis 17 includes the following two processes.
　工程１）突起部１７２ｃの根元に切欠きの底が最も近づいた状態を保つように、凸部１６４を根元まで開口部に挿入する工程
　工程２）出っ張り部１７４の先端面（当接部）を、ＬＥＤ基板１６の側面（切欠きが形成されている側面に対向する側面）に当接させる工程
　工程１において、作業者は、凸部１６４を根元まで(凸部１６４の大部分がバックライトシャーシ１７の背面側に位置するまで）開口部に挿入する。その結果、凸部１６４とバックライトシャーシ１７の背面とは互いに接することとなる。 Step 1) Step of inserting the convex portion 164 into the opening to the base so that the bottom of the notch is closest to the base of the protrusion 172c Step 2) The tip surface (contact portion) of the protruding portion 174 The step of contacting the side surface of the LED substrate 16 (the side surface opposite to the side surface on which the notch is formed) In step 1, the operator moves the convex portion 164 to the root (most of the convex portion 164 is a backlight chassis). 17) until it is on the back side. As a result, the convex portion 164 and the back surface of the backlight chassis 17 are in contact with each other.
　即ち、ＬＥＤ基板１６に水平方向（Ｘ軸方向）の力が多少加わった場合、凸部１６４とバックライトシャーシ１７の背面との間の摩擦力により、水平方向の力は打ち消される。そして、ＬＥＤ基板１６に摩擦力を超える水平方向の力が加わった場合であっても、突起部１７２ｃが、ＬＥＤ基板１６の水平方向への移動を妨げる。 That is, when a horizontal force (X-axis direction) is slightly applied to the LED substrate 16, the horizontal force is canceled by the frictional force between the convex portion 164 and the back surface of the backlight chassis 17. Even when a horizontal force exceeding the frictional force is applied to the LED substrate 16, the protrusion 172 c prevents the LED substrate 16 from moving in the horizontal direction.
　工程２において、作業者は、ＬＥＤ基板１６の凸部１６４が開口部にしっかり挿入された状態を保ったままＬＥＤ基板１６を平面Ｐ側に押し込む。その結果、出っ張り部１７４の先端面はＬＥＤ基板１６の側面に当接する。 In step 2, the operator pushes the LED board 16 toward the plane P side while keeping the convex part 164 of the LED board 16 firmly inserted in the opening. As a result, the tip end surface of the protruding portion 174 contacts the side surface of the LED substrate 16.
　なお、作業者は、ＬＥＤ基板１６をバックライトシャーシ１７に取り付けた後、公知の方法で、キャビネット（フロントキャビネット１０及びバックキャビネット２０）の内部に各種パーツを組み込むことにより、図１３に示すような外観の表示装置１を製造できる。 The worker attaches the LED board 16 to the backlight chassis 17 and then incorporates various parts into the cabinet (the front cabinet 10 and the back cabinet 20) by a known method, as shown in FIG. The external display device 1 can be manufactured.
