Description

表示装置、及びテレビ受信装置Display device and television receiver
　本発明は、表示装置、及びテレビ受信装置に関する。 The present invention relates to a display device and a television receiver.
　テレビ、携帯電話、携帯情報端末等の表示装置に、液晶パネルが汎用されている。液晶パネルは、画像を表示させるために、外部の光を利用する必要がある。そのため、この種の表示装置は、特許文献１に示されるように、液晶パネルの他に、液晶パネルに光を供給するための照明装置（所謂、バックライト装置）を備えている。この照明装置は、液晶パネルの背面側に配されており、面状に広がった光を液晶パネルの背面に向けて照射するように構成されている。 Liquid crystal panels are widely used in display devices such as televisions, mobile phones, and portable information terminals. The liquid crystal panel needs to use external light in order to display an image. Therefore, as shown in Patent Document 1, this type of display device includes an illumination device (a so-called backlight device) for supplying light to the liquid crystal panel in addition to the liquid crystal panel. This illuminating device is arranged on the back side of the liquid crystal panel, and is configured to irradiate light spread in a planar shape toward the back side of the liquid crystal panel.
　なお、特許文献１に示されるように、液晶パネルは、その周縁部分にある非表示部が２つの枠状部材間で挟持された状態で、照明装置に固定されている。液晶パネルの表示部は、枠状部材の内側に配されている。 In addition, as shown in Patent Document 1, the liquid crystal panel is fixed to the lighting device in a state where a non-display portion at a peripheral portion is sandwiched between two frame-like members. The display part of the liquid crystal panel is arranged inside the frame-shaped member.
　近年、表示装置の大型化等の理由により、前記枠状部材で支えなければならない液晶パネルの質量が増加している。また、デザイン性の向上等の理由により、液晶パネルの表示部の面積に対する非表示部の面積が狭小化されており、前記枠状部材が液晶パネルに接触できる面積の比率が低下している。そのため、液晶パネルが自重で撓まないように、近年、前記枠状部材によって液晶パネルの周縁部分が比較的、大きな力で挟持されている。 In recent years, the mass of liquid crystal panels that must be supported by the frame-like member has increased due to reasons such as an increase in the size of display devices. In addition, the area of the non-display portion with respect to the area of the display portion of the liquid crystal panel is reduced for reasons such as improvement in design, and the ratio of the area where the frame-shaped member can contact the liquid crystal panel is reduced. Therefore, in recent years, the peripheral portion of the liquid crystal panel is sandwiched by the frame-like member with a relatively large force so that the liquid crystal panel is not bent by its own weight.

（発明が解決しようとする課題）
　しかしながら、前記枠状部材で、液晶パネルの非表示部を強く挟み付けると、液晶パネルの角部等において押圧力が必要以上に加えられてしまう。その結果、その押圧力が表示部にまで伝播して、表示部に押しムラと呼ばれる表示ムラが発生してしまい問題となっている。 (Problems to be solved by the invention)
However, if the non-display portion of the liquid crystal panel is strongly sandwiched between the frame-shaped members, a pressing force is applied more than necessary at the corners of the liquid crystal panel. As a result, the pressing force propagates to the display unit, and display unevenness called press unevenness occurs in the display unit, which is a problem.
　本発明の目的は、２つの枠状部材で挟持された表示パネルに押しムラが発生することが抑制された表示装置を提供することである。 An object of the present invention is to provide a display device in which occurrence of pressing unevenness in a display panel sandwiched between two frame members is suppressed.

The LEDs 16 of the LED unit LU are opposed to the end surfaces 19c and 19d while maintaining a predetermined interval. The end surfaces 19c and 19d of the light guide plate 19 are light incident surfaces 19c and 19d on which light emitted from the LED 16 is incident. The light guide plate 19 has a function of raising and emitting light incident from the light incident surfaces 19c and 19d so as to be directed toward the front side while propagating inside.

　表側枠状本体部１３ａは、全体的には、枠状をなした略扁平な板状部材である。表側枠状本体部１３ａは、液晶パネル１１の非表示部１２０に対して間隔を保ちつつ、非表示部１２０の表側と対向している。なお、表側枠状本体部１３ａは、表側から平面視した際、液晶パネル１１の非表示部１２０を完全に覆う形で対向してもよいし、非表示部１２０の一部（例えば、非表示部１２０の外周側の部分）を覆う形で対向してもよい。本実施形態の場合、表側枠状本体部１３ａは、非表示部１２０の外周側の部分を、環状に覆う形で対向している。 The front-side frame-like main body 13a is a substantially flat plate-like member having a frame shape as a whole. The front side frame-shaped main body part 13 a faces the front side of the non-display part 120 while maintaining a distance from the non-display part 120 of the liquid crystal panel 11. The front side frame-shaped main body 13a may face the non-display part 120 of the liquid crystal panel 11 so as to cover the non-display part 120 when viewed from the front side, or a part of the non-display part 120 (for example, non-display) You may oppose in the form which covers the part of the outer peripheral side of the part 120). In the case of this embodiment, the front side frame-shaped main body part 13a opposes the outer peripheral side part of the non-display part 120 so as to cover the ring shape.
　表側枠状本体部１３ａの内側は、開口されており、その開口した部分から液晶パネル１１の表示部１１０が露出している。そして、矩形型の枠状をなした表側枠状本体部１３ａの内周縁のうち、辺毎に押圧部１３ｂが設けられている。本実施形態の場合、ベゼル１３には、４つの押圧部１３ｂが設けられている。そして、各押圧部１３ｂは、表側枠状本体部１３ａの内周縁から非表示部１２０の表側に向かって延びた形をなしている。つまり、各押圧部１３ｂは、表側枠状本体部１３ａから非表示部１２０の表側に向かって盛り上がった形をなしている。 The inside of the front side frame main body 13a is opened, and the display unit 110 of the liquid crystal panel 11 is exposed from the opened part. And the press part 13b is provided for every edge | side among the inner periphery of the front side frame-shaped main-body part 13a which made the rectangular frame shape. In the case of this embodiment, the bezel 13 is provided with four pressing portions 13b. And each press part 13b has comprised the shape extended toward the front side of the non-display part 120 from the inner periphery of the front side frame-shaped main-body part 13a. That is, each pressing portion 13 b has a shape that rises from the front side frame-shaped main body portion 13 a toward the front side of the non-display portion 120.
　各押圧部１３ｂは、矩形型の枠状をなした液晶パネル１１の非表示部１２０の辺毎に割り当てられており、そして、各押圧部１３ｂは、非表示部１２０の各辺（枠辺）に沿って延びた形をなしている。そして、図４等に示されるように、４つの押圧部１３ｂは、液晶パネル１１の表示部１１０を囲むような形をなしている。本実施形態の場合、４つの押圧部１３ｂは、略矩形状をなしている。 Each pressing portion 13b is assigned to each side of the non-display portion 120 of the liquid crystal panel 11 having a rectangular frame shape, and each pressing portion 13b is each side (frame side) of the non-display portion 120. It has a shape extending along. Then, as shown in FIG. 4 and the like, the four pressing portions 13b are shaped to surround the display portion 110 of the liquid crystal panel 11. In the case of the present embodiment, the four pressing portions 13b have a substantially rectangular shape.
　押圧部１３ｂは、表側枠状本体部１３ａの内周縁に延設された板状部分が加工された物からなり、液晶パネル１１の非表示部１２０の表側と接触する接触部１３ｂ１と、この接触部１３ｂ１と表側枠状本体部１３ａとの間を接続する接続部１３ｂ２とを備えている。接触部１３ｂ１は、液晶パネル１１（非表示部１２０）の板面に対して略平行に配された板状をなしている。そして、接続部１３ｂ２は、表側枠状本体部１３ａ側から接触部１３ｂ１側にかけて、徐々に表示部１１０側に近付くように若干、傾斜しつつ、表側枠状本体部１３ａから非表示部１２０に向かって延びた板状をなしている。 The pressing portion 13b is formed by processing a plate-like portion extending on the inner peripheral edge of the front side frame-like main body portion 13a, and the contact portion 13b1 that comes into contact with the front side of the non-display portion 120 of the liquid crystal panel 11 and this contact A connecting portion 13b2 for connecting the portion 13b1 and the front-side frame-like main body portion 13a. The contact portion 13b1 has a plate shape arranged substantially parallel to the plate surface of the liquid crystal panel 11 (non-display portion 120). Then, the connecting portion 13b2 is slightly inclined from the front side frame-like main body portion 13a side to the contact portion 13b1 side, gradually moving toward the display portion 110 side, and is directed from the front side frame-like main body portion 13a toward the non-display portion 120. It has an elongated plate shape.
　押圧部１３ｂの接触部１３ｂ１と接続部１３ｂ２とは、表側枠状本体部１３ａの枠辺毎に割り当てられており、表側枠状本体部１３ａの各内周縁に延設され、かつベゼル１３（、表側枠状本体部１３ａ）の各枠辺に沿って細長く延びた各々の板状部分が、それぞれ２個所で折り曲げられることにより形成される。押圧部１３ｂは、各板状部分に対して、所謂、絞り加工を施すことにより、形成することができる。このような押圧部１３ｂは、弾性をそなえており、接触部１３ｂ１は、液晶パネル１１の非表示部１２０に対して弾性的に押圧する。押圧部１３ｂの接触部１３ｂ１が非表示部１２０を押圧すると、押圧部１３ｂの接続部１３ｂ２等が若干、撓んで弾性的に変形する。なお、押圧部１３ｂの接触部１３ｂ１が非表示部１２０から離されると、押圧部１３ｂの接続部１３ｂ２は、撓みが解消されて元の形状に戻る。 The contact part 13b1 and the connection part 13b2 of the pressing part 13b are assigned to each frame side of the front side frame-like main body part 13a, are extended to each inner peripheral edge of the front side frame-like main body part 13a, and the bezel 13 (, Each plate-like portion that is elongated along each frame side of the front-side frame-like main body portion 13a) is formed by being bent at two locations. The pressing portion 13b can be formed by subjecting each plate-like portion to a so-called drawing process. Such a pressing part 13 b has elasticity, and the contact part 13 b 1 elastically presses against the non-display part 120 of the liquid crystal panel 11. When the contact portion 13b1 of the pressing portion 13b presses the non-display portion 120, the connecting portion 13b2 of the pressing portion 13b is slightly bent and elastically deformed. When the contact portion 13b1 of the pressing portion 13b is separated from the non-display portion 120, the connection portion 13b2 of the pressing portion 13b is released from the bending and returns to the original shape.
　４つの押圧部１３ｂは、ベゼル１３の角部及び非表示部１２０の角部において、互いに交差しないように、互いに間隔を保つように離れている。つまり、ベゼル１３の角部（表側枠状本体部１３ａの角部）には、押圧部１３ｂが形成されておらず、隣り合った押圧部１３ｂ同士の間には隙間１３ｄが形成されている。そして、この隙間１３ｄは、矩形型の枠状をなす非表示部１２０のうち、４つの角部に１つずつ割り当てられている。この隙間１３ｄでは、ベゼル１３によって、液晶パネル１１の非表示部１２０が押圧されない個所となっている。この隙間１３ｄのことを、特に、非押圧部１３ｄと称する。本実施形態の場合、非押圧部１３ｄは、ベゼル１３の四隅に設けられている。つまり、押圧部１３ｂは、液晶パネル１１の非表示部１２０を全周に亘って押圧するものではなく、四隅（４つの角部）以外の非表示部１２０を押圧するものである。 The four pressing portions 13b are spaced apart from each other so as not to cross each other at the corner of the bezel 13 and the corner of the non-display portion 120. That is, the pressing portion 13b is not formed at the corner portion of the bezel 13 (the corner portion of the front side frame-shaped main body portion 13a), and a gap 13d is formed between the adjacent pressing portions 13b. The gaps 13d are assigned to four corners of the non-display part 120 having a rectangular frame shape. In the gap 13d, the non-display portion 120 of the liquid crystal panel 11 is not pressed by the bezel 13. This gap 13d is particularly referred to as a non-pressing portion 13d. In the case of the present embodiment, the non-pressing portion 13 d is provided at the four corners of the bezel 13. That is, the pressing portion 13b does not press the non-display portion 120 of the liquid crystal panel 11 over the entire circumference, but presses the non-display portion 120 other than the four corners (four corner portions).
　液晶表示装置１０は、液晶パネル１１の表示部１１０に画像を表示させる際、照明装置１２が備える各ＬＥＤユニットＬＵの各ＬＥＤ１６が発光（点灯）する。各ＬＥＤ１６が発光すると、導光板１９の端面（光入射面）１９ｃ，１９ｄから導光板１９の内部に光が入射する。入射した光は、導光板１９の裏側に敷かれている反射シート２０、導光板１９の裏面１９ｂ又は表面１９ａに形成されている反射部等によって反射等されて、導光板１９内を進みつつ、その表側の板面（光出射面）１９ａから出射する。板面１９ａから出射した光は、光学シート１５を通過して面状に広がった光となり、フレーム２１の内側の開口部を通過して液晶パネル１１の表示部１１０の裏側に照射される。液晶パネル１１は、この照明装置１２からの光を利用して、表示部１１０の表側に画像を表示させている。 When the liquid crystal display device 10 displays an image on the display unit 110 of the liquid crystal panel 11, each LED 16 of each LED unit LU included in the illumination device 12 emits light (lights up). When each LED 16 emits light, light enters the light guide plate 19 from the end faces (light incident surfaces) 19 c and 19 d of the light guide plate 19. The incident light is reflected by the reflecting sheet 20 laid on the back side of the light guide plate 19, the reflecting portion formed on the back surface 19 b or the front surface 19 a of the light guide plate 19, and the like while traveling through the light guide plate 19. The light is emitted from the front side plate surface (light emitting surface) 19a. The light emitted from the plate surface 19 a passes through the optical sheet 15 and spreads in a planar shape, passes through the opening inside the frame 21, and is irradiated to the back side of the display unit 110 of the liquid crystal panel 11. The liquid crystal panel 11 displays an image on the front side of the display unit 110 using light from the illumination device 12.
　本実施形態の液晶表示装置１０は、画像が表側に表示される表示部１１０と、この表示部１１０の周縁に設けられる枠状をなした非表示部１２０とを有する液晶パネル１１と、表示部１１０を囲む形で非表示部１２０の裏側に宛がわる枠状をなしたフレーム（裏側枠状部材）２１と、表示部１１０を囲む形で非表示部１２０の表側と対向する枠状をなした表側枠状本体部（枠状本体部）１３ａと、この表側枠状本体部１３ａから非表示部１２０の表側に向かって各々が盛り上がった形をなし、互いに交差しないように、各々が表示部１１０を囲む形で非表示部１２０の各枠辺に沿って延び、各々が非表示部１２０の表側を押圧しつつフレーム（裏側枠状部材）２１との間で非表示部１２０を挟持する複数の押圧部１３ｂと、隣り合った押圧部１３ｂ同士の間に形成される隙間からなる複数の非押圧部１３ｄとを有するベゼル（表側枠状部材）１３と、を備える。 The liquid crystal display device 10 of the present embodiment includes a liquid crystal panel 11 having a display unit 110 on which an image is displayed on the front side, and a non-display unit 120 having a frame shape provided at the periphery of the display unit 110, and a display unit A frame (back frame member) 21 having a frame shape that surrounds the non-display portion 120 so as to surround the 110 and a frame shape that faces the front side of the non-display portion 120 so as to surround the display portion 110 are formed. The front-side frame-like main body portion (frame-like main-body portion) 13a and the front-side frame-like main body portion 13a are swelled from the front-side frame-like main body portion 13a toward the front side of the non-display portion 120. 110, extending along each frame side of the non-display portion 120 so as to surround 110, and each holding the non-display portion 120 with the frame (back frame member) 21 while pressing the front side of the non-display portion 120. The pressing portion 13b and the adjacent pressing It comprises a bezel (front frame member) 13, a and a plurality of non-pressing portion 13d formed of a gap formed between 13b together.
　前記液晶表示装置１０において、液晶パネル１１の非表示部１２０は、ベゼル（表側枠状部材）１３が有する複数の押圧部１３ｂと、フレーム（裏側枠状部材）２１との間で挟持される。そして、ベゼル（表側枠状部材）１３は、隣り合った押圧部１３ｂ同士の間に形成される隙間からなる複数の非押圧部１３ｄを有しているため、液晶パネル１１の非表示部１２０は、表側から押圧されない個所を備えている。仮に、隣り合った押圧部１３ｂ同士が互いに交差するように繋がっていると、その繋がった部分による押圧力が非表示部１２０のみならず、表示部１１０にまで伝播して影響するため、液晶パネル１１に押しムラと呼ばれる表示ムラが発生してしまうことがある。しかしながら、液晶表示装置１０では、上記構成を備えることにより、ベゼル（表側枠状部材）１３とフレーム（裏側枠状部材）２１で挟持された液晶パネル１１に押しムラが発生することが抑制される。 In the liquid crystal display device 10, the non-display portion 120 of the liquid crystal panel 11 is sandwiched between a plurality of pressing portions 13 b included in the bezel (front frame member) 13 and the frame (back frame member) 21. And since the bezel (front side frame-shaped member) 13 has a plurality of non-pressing parts 13d consisting of gaps formed between adjacent pressing parts 13b, the non-display part 120 of the liquid crystal panel 11 is , It has a part that is not pressed from the front side. If the adjacent pressing portions 13b are connected so as to cross each other, the pressing force by the connected portions propagates and affects not only the non-display portion 120 but also the display portion 110, so that the liquid crystal panel 11 may cause display unevenness called push unevenness. However, in the liquid crystal display device 10, by providing the above configuration, it is possible to suppress the occurrence of pressing unevenness in the liquid crystal panel 11 sandwiched between the bezel (front frame member) 13 and the frame (back frame member) 21. .
　また、本実施形態の液晶表示装置１０では、非表示部１２０が、矩形型の枠状をなし、押圧部１３ｂが、非表示部１２０の各角部（四隅）において互いに交差しないように、各々が表示部１１０を囲む形で非表示部１２０の各枠辺に沿って延び、非押圧部１３ｄが、非表示部１２０の各角部に１つずつ割り当てられている。このように、非表示部１２０が矩形型の枠状をなす場合（つまり、液晶パネル１１が矩形状の場合）、液晶パネル１１の非表示部１２０の四隅に、非押圧部１３ｄが割り当てられることが好ましい。なお、他の実施形態においては、非表示部１２０が、正方形型の枠状をなすものであってもよい。 Further, in the liquid crystal display device 10 of the present embodiment, the non-display portion 120 has a rectangular frame shape, and the pressing portion 13b does not cross each other at each corner (four corners) of the non-display portion 120. Extends along each frame side of the non-display portion 120 so as to surround the display portion 110, and one non-pressing portion 13 d is assigned to each corner of the non-display portion 120. As described above, when the non-display portion 120 has a rectangular frame shape (that is, when the liquid crystal panel 11 is rectangular), the non-pressing portions 13d are assigned to the four corners of the non-display portion 120 of the liquid crystal panel 11. Is preferred. In other embodiments, the non-display unit 120 may have a square frame shape.
　また、本実施形態の液晶表示装置１０おいて、押圧部１３ｂは、弾性を備えており、非表示部１２０の表側を弾性的に押圧するものである。このような、押圧部１３ｂを備えることにより、上述したように押しムラの発生を抑制しつつ、ベゼル１３とフレーム２１との間で液晶パネル１１を確実に挟持することができる。 Further, in the liquid crystal display device 10 of the present embodiment, the pressing portion 13b has elasticity, and elastically presses the front side of the non-display portion 120. By providing such a pressing portion 13b, the liquid crystal panel 11 can be securely sandwiched between the bezel 13 and the frame 21 while suppressing the occurrence of uneven pressing as described above.
　また、本実施形態の液晶表示装置１０において、押圧部１３ｂは、表側枠状本体部１３ａの内周縁に延設され、表側枠状本体部１３ａの枠辺毎に割り当てられた板状部分の加工物からなり、非押圧部１３ｄが、表側枠状本体部１３ａの内周縁に前記板状部分が延設されていない部分からなる。このような構成の押圧部１３ｂ及び非押圧部１３ｄは、例えば、絞り加工等によって加工することが可能であり、生産性に優れる。 Further, in the liquid crystal display device 10 of the present embodiment, the pressing portion 13b extends to the inner peripheral edge of the front side frame-like main body portion 13a, and processes the plate-like portion assigned to each frame side of the front-side frame-like main body portion 13a. The non-pressing part 13d consists of a part in which the said plate-shaped part is not extended in the inner periphery of the front side frame-shaped main-body part 13a. The pressing portion 13b and the non-pressing portion 13d having such a configuration can be processed by, for example, drawing, and are excellent in productivity.
　また、本実施形態の液晶表示装置１０において、フレーム（裏側枠状部材）２１は、フレーム（裏側枠状部材）２１の内側の開口部を通過するように表示部１１０の裏側に向けて光を出射する照明装置１２の一部からなる。このように、照明装置１２の一部を構成する枠状部材を、液晶パネル１１を挟持するための裏側枠状部材として利用してもよい。他の実施形態においては、裏側枠状部材として、照明装置１２の構成部品以外のものを利用してもよい。 Further, in the liquid crystal display device 10 of the present embodiment, the frame (back frame member) 21 emits light toward the back side of the display unit 110 so as to pass through the opening inside the frame (back frame member) 21. It consists of a part of the illuminating device 12 to emit. Thus, the frame-shaped member that constitutes a part of the lighting device 12 may be used as a back-side frame-shaped member for sandwiching the liquid crystal panel 11. In other embodiment, you may utilize things other than the component of the illuminating device 12 as a back side frame-shaped member.
　＜実施形態２＞
　次いで、本発明の実施形態２を、図６から図９を参照しつつ説明する。なお、以降の各実施形態では、実施形態１と同じ部分については、実施形態１のものと同じ符号を付して、その詳細な説明は省略する。図６は、実施形態２に係る表側から見た液晶表示装置１０Ａの平面図であり、図７は、実施形態２におけるベゼル１３Ａの角部の拡大図であり、図８は、実施形態２のベゼル１３Ａを裏側から見た平面図であり、図９は、図６のＢ－Ｂ’線断面図である。 <Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIGS. In the following embodiments, the same parts as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted. FIG. 6 is a plan view of the liquid crystal display device 10A viewed from the front side according to the second embodiment, FIG. 7 is an enlarged view of a corner portion of the bezel 13A in the second embodiment, and FIG. FIG. 9 is a plan view of the bezel 13A viewed from the back side, and FIG. 9 is a cross-sectional view taken along line BB ′ of FIG.
　本実施形態の液晶表示装置１０Ａの基本的な構成は、実施形態１の液晶表示装置１０と同様であり、実施形態１と同様の構成の照明装置１２Ａを備えている。本実施形態の液晶表示装置１０Ａは、実施形態１の液晶表示装置１０に、弱押圧部（スペーサ部）２２を追加した構成となっている。弱押圧部２２は、実施形態１と同様の構成を備えるベゼル１３Ａの四隅に、それぞれ１つずつ割り当てられている。ベゼル１３Ａの四隅には、実施形態１と同様、隣り合った押圧部１３ｂ同士の間に形成される隙間１３ｄがある。弱押圧部２２は、この隙間１３ｄを塞ぐような形で、非表示部１２０の各角部に配されている。 The basic configuration of the liquid crystal display device 10A of the present embodiment is the same as that of the liquid crystal display device 10 of the first embodiment, and includes a lighting device 12A having the same configuration as that of the first embodiment. The liquid crystal display device 10A of the present embodiment has a configuration in which a weak pressing portion (spacer portion) 22 is added to the liquid crystal display device 10 of the first embodiment. One weak pressing portion 22 is assigned to each of the four corners of the bezel 13A having the same configuration as in the first embodiment. At the four corners of the bezel 13A, there are gaps 13d formed between the adjacent pressing portions 13b as in the first embodiment. The weak pressing portion 22 is arranged at each corner portion of the non-display portion 120 so as to close the gap 13d.
　弱押圧部２２は、図８に示されるように、平面視した際に、略Ｌ字状をなしており、ベゼル１３Ａの角部（表側枠状本体部１３ａの角部）に沿った形をなしている。弱押圧部２２は、液晶パネル１１の非表示部１２０と表側枠状本体部１３ａとの間の間隔（距離）と同程度の厚みを備えている。弱押圧部２２は、例えば、ポリエチレンテレフタレート（ＰＥＴ）等のプラスチック材料から形成される。本実施形態の弱押圧部２２は、黒色顔料が添加されたＰＥＴ樹脂の成型品からなる。弱押圧部２２は、ベゼル１３Ａの表側枠状本体部１３ａに対して、両面粘着シート等を利用して固定されている。なお、弱押圧部２２の厚み（Ｘ軸方向の長さ）は、上述したように、液晶パネル１１の非表示部１２０と表側枠状本体部１３ａとの間の間隔（距離）と同程度に設定されており、非表示部１２０を表側から押圧部１３ｂよりも強く押圧しないように設定されている。弱押圧部２２の押圧力は、押圧部１３ｂと比べて非常に小さく、液晶パネル１１に押しムラ（表示ムラ）が発生しない程度に設定されている。つまり、弱押圧部２２は、押圧部１３ｂと比べて、押圧力がかなり弱くなっている。本実施形態の弱押圧部２２は、金属製の押圧部１３ｂよりも柔らかい材質から形成されている。このように、押圧部１３ｂよりも柔らかい材質で、弱押圧部２２が形成されていると、押しムラが発生するような強い力で非表示部１２０の角部を押圧することが抑制される。 As shown in FIG. 8, the weak pressing portion 22 is substantially L-shaped when viewed in plan, and has a shape along the corner of the bezel 13A (the corner of the front-side frame-shaped main body 13a). There is no. The weak pressing portion 22 has a thickness comparable to the interval (distance) between the non-display portion 120 of the liquid crystal panel 11 and the front side frame-shaped main body portion 13a. The weak pressing part 22 is formed from plastic materials, such as a polyethylene terephthalate (PET), for example. The weak pressing part 22 of this embodiment consists of a molded product of PET resin to which a black pigment is added. The weak pressing portion 22 is fixed to the front side frame-like main body portion 13a of the bezel 13A using a double-sided adhesive sheet or the like. As described above, the thickness (length in the X-axis direction) of the weak pressing portion 22 is approximately the same as the interval (distance) between the non-display portion 120 of the liquid crystal panel 11 and the front side frame-shaped main body portion 13a. It is set so that the non-display part 120 is not pressed more strongly than the pressing part 13b from the front side. The pressing force of the weak pressing portion 22 is very small as compared with the pressing portion 13b, and is set to such an extent that uneven pressing (display unevenness) does not occur in the liquid crystal panel 11. In other words, the pressing force of the weak pressing portion 22 is considerably weaker than that of the pressing portion 13b. The weak pressing part 22 of this embodiment is formed of a softer material than the metal pressing part 13b. As described above, when the weak pressing portion 22 is formed of a material softer than the pressing portion 13b, it is possible to suppress the corner portion of the non-display portion 120 from being pressed with a strong force that causes pressing unevenness.
　本実施形態の液晶表示装置１０Ａは、このような弱押圧部（スペーサ部）２２を備えることにより、隣り合った押圧部１３ｂ同士の間に形成される隙間１３ｄを塞ぐことができ、その隙間１３ｄから液晶表示装置１０Ａの内部にゴミ等の異物が進入することが抑制される。なお、弱押圧部（スペーサ部）２２は、ベゼル１３Ａと液晶パネル１１の非表示部１２０との間に介在しつつ、隣り合った押圧部１３ｂ同士の間に形成される隙間１３ｄを塞ぐものである。その都合上、弱押圧部（スペーサ部）２２は、結果的に、液晶パネル１１の非表示部１２０と接触して、非表示部１２０を非常に弱い力で押圧する構成となっている。 The liquid crystal display device 10A according to the present embodiment includes such a weak pressing portion (spacer portion) 22 so that the gap 13d formed between the adjacent pressing portions 13b can be closed, and the gap 13d. From entering foreign matter such as dust into the liquid crystal display device 10A. The weak pressing portion (spacer portion) 22 is interposed between the bezel 13A and the non-display portion 120 of the liquid crystal panel 11 and closes the gap 13d formed between the adjacent pressing portions 13b. is there. Therefore, the weak pressing portion (spacer portion) 22 is configured to come into contact with the non-display portion 120 of the liquid crystal panel 11 and press the non-display portion 120 with a very weak force.
　特に、本実施形態の弱押圧部２２は、黒色であり遮光性を備えている。そのため、液晶表示装置１０Ａの内部（内部の光源）から外部に、隣り合った押圧部１３ｂ同士の間に形成される隙間１３ｄを通って光が漏れ出すことが抑制される。仮に、隙間１３ｄから光が漏れ出すと、その光が表示パネルの表示ムラの原因となってしまうため、本実施形態のように、弱押圧部２２が遮光性を備えていることが好ましい。なお、他の実施形態においては、遮光性を備えていない弱押圧部２２を利用してもよい。 Particularly, the weak pressing portion 22 of the present embodiment is black and has a light shielding property. Therefore, light is prevented from leaking from the inside (internal light source) of the liquid crystal display device 10A to the outside through the gap 13d formed between the adjacent pressing portions 13b. If light leaks from the gap 13d, the light causes display unevenness of the display panel. Therefore, it is preferable that the weak pressing portion 22 has light shielding properties as in the present embodiment. In other embodiments, a weak pressing portion 22 that does not have light shielding properties may be used.

　本実施形態の液晶表示装置１０Ｂは、実施形態１と同様の構成を備えた照明装置１２Ｂを備えている。本実施形態の液晶表示装置１０Ｂは、実施形態１のベゼル１３に替えて、ベゼル１３Ｂを用いたものからなる。ベゼル１３側枠状本体部１３Ｂａ及び周壁部１３Ｂｃの構成は、実施形態１のベゼル１３と同様である。ただし、本実施形態のベゼル１３Ｂの押圧部１３Ｂｂ及び非押圧部１３Ｂｄの構成が、実施形態１のベゼル１３とは異なっている。以下、主として、押圧部１３Ｂｂ及び非押圧部１３Ｂｄについて、詳細に説明する。 The liquid crystal display device 10B of the present embodiment includes an illumination device 12B having the same configuration as that of the first embodiment. The liquid crystal display device 10B according to the present embodiment is configured by using the bezel 13B instead of the bezel 13 according to the first embodiment. The configurations of the bezel 13 side frame-shaped main body portion 13Ba and the peripheral wall portion 13Bc are the same as those of the bezel 13 of the first embodiment. However, the configuration of the pressing portion 13Bb and the non-pressing portion 13Bd of the bezel 13B of the present embodiment is different from the bezel 13 of the first embodiment. Hereinafter, the pressing portion 13Bb and the non-pressing portion 13Bd will be mainly described in detail.
　ベゼル１３Ｂが備える押圧部１３Ｂｂ及び非押圧部１３Ｂｄは、表側枠状本体部１３Ｂａの内周縁に延設された環状をなす板状部分を加工した物からなる。そのため、図１０に示されるように、ベゼル１３Ｂを表側から平面視した際、押圧部１３Ｂｂ及び非押圧部１３Ｂｄが、環状に繋がった形をなしている。押圧部１３Ｂｂ及び非押圧部１３Ｂｄは、形成される前は、環状に繋がった枠状の板状部材（板状部分）となっている。 The pressing portion 13Bb and the non-pressing portion 13Bd included in the bezel 13B are formed by processing an annular plate-like portion extending on the inner peripheral edge of the front side frame-like main body portion 13Ba. Therefore, as shown in FIG. 10, when the bezel 13B is viewed from the front side, the pressing portion 13Bb and the non-pressing portion 13Bd are connected in a ring shape. Before being formed, the pressing portion 13Bb and the non-pressing portion 13Bd are frame-like plate-like members (plate-like portions) connected in an annular shape.
　押圧部１３Ｂｂは、表側枠状本体部１３Ｂａの内周縁に延設された環状をなす前記板状部材（板状部分）のうち、表側枠状本体部１３Ｂａの枠辺毎に割り当てられてられる。つまり、押圧部１３Ｂｂは、表側枠状本体部１３Ｂａに対して、実施形態１の押圧部１３ｂと同様の個所に割り当てられている。押圧部１３Ｂｂは、実施形態１と略同様な構成を備える接触部１３Ｂｂ１及び接続部１３Ｂｂ２からなる。 The pressing portion 13Bb is assigned to each frame side of the front-side frame-like main body portion 13Ba among the annular plate-like members (plate-like portions) extending around the inner peripheral edge of the front-side frame-like main body portion 13Ba. That is, the pressing portion 13Bb is assigned to the same position as the pressing portion 13b of the first embodiment with respect to the front side frame-shaped main body portion 13Ba. The pressing portion 13Bb includes a contact portion 13Bb1 and a connection portion 13Bb2 that have substantially the same configuration as that of the first embodiment.
　これに対して、非押圧部１３Ｂｄは、表側枠状本体部１３Ｂａの内周縁に延設された環状をなす前記板状部材（板状部分）のうち、液晶パネル１１の非表示部１２０の表側に接触しないように非表示部１２０から浮き上がった形をなす部分からなる。図１１に示されるように、非押圧部１３Ｂｄは、液晶パネル１１の非表示部１２０と接触しないように、非表示部１２０から離されている。つまり、本実施形態においても、実施形態１と同様、液晶パネル１１の非表示部１２０の四隅（角部）は、ベゼル１３Ｂの押圧部１３Ｂｂによって押圧されない構成となっている。このように、表側枠状本体部１３Ｂａに環状に設けた板状部材（板状部分）を、部分的に、液晶パネル１１の非表示部１２０から浮き上がる形で曲げ加工等して、ベゼル１３Ｂに非押圧部１３Ｂｄを形成してもよい。このような押圧部１３Ｂｂ及び非押圧部１３Ｂｄは、例えば、絞り加工によって形成されてもよい。 On the other hand, the non-pressing portion 13Bd is a front side of the non-display portion 120 of the liquid crystal panel 11 among the plate-like members (plate-like portions) that form an annular shape extending on the inner peripheral edge of the front side frame-like main body portion 13Ba. It consists of the part which makes the shape which floated from the non-display part 120 so that it may not contact. As shown in FIG. 11, the non-pressing portion 13 </ b> Bd is separated from the non-display portion 120 so as not to contact the non-display portion 120 of the liquid crystal panel 11. That is, also in the present embodiment, like the first embodiment, the four corners (corner portions) of the non-display portion 120 of the liquid crystal panel 11 are not pressed by the pressing portion 13Bb of the bezel 13B. In this manner, the plate-like member (plate-like portion) provided in an annular shape on the front side frame-like main body portion 13Ba is partially bent and lifted from the non-display portion 120 of the liquid crystal panel 11 to form the bezel 13B. The non-pressing part 13Bd may be formed. Such pressing part 13Bb and non-pressing part 13Bd may be formed by drawing, for example.
　本実施形態の場合、非押圧部１３Ｂｄにも、板状部分が形成されているため、実施形態１と比べて、異物等が液晶表示装置１０Ｂの内部に進入し難く、光が外部に漏れにくくなっている。また、本実施形態の場合、実施形態１と比べて、液晶表示装置１０Ｂの表側に露出する押圧部１３Ｂｂの端部（エッジ）が少ない構成となっている。そのため、例えば、液晶表示装置１０Ｂの組み立て作業時において、押圧部１３Ｂｂの端部（エッジ）が他の部品や作業者に接触して引っ掛かることが抑制される。 In the case of the present embodiment, since a plate-like portion is also formed in the non-pressing portion 13Bd, compared to the first embodiment, foreign substances and the like are less likely to enter the liquid crystal display device 10B, and light is less likely to leak to the outside. It has become. Further, in the case of the present embodiment, the end portion (edge) of the pressing portion 13Bb exposed to the front side of the liquid crystal display device 10B is less than that in the first embodiment. Therefore, for example, at the time of assembling the liquid crystal display device 10B, it is suppressed that the end (edge) of the pressing portion 13Bb comes into contact with other parts or an operator and is caught.
　なお、本実施形態の液晶表示装置１０Ｂにおいても、実施形態１と同様、ベゼル（表側枠状部材）１３Ｂとフレーム（裏側枠状部材）２１で挟持された液晶パネル１１に押しムラが発生することが抑制される。 In the liquid crystal display device 10B of the present embodiment, as in the first embodiment, the liquid crystal panel 11 sandwiched between the bezel (front side frame-like member) 13B and the frame (back side frame-like member) 21 may cause uneven pressing. Is suppressed.
