本実施形態では、上記のように、表示パネル支持部材４が反射シート１１の後面のうち外周部近傍を除く内側領域（図９の斜線部分Ａ）を押圧するように反射シート１１に向かって窪んだ第１凹部４１（図８の斜線部分Ｂ）を有することによって、たとえば、反射シート１１の外周部近傍のみを押さえる場合と異なり、表示パネル支持部材４の第１凹部４１により、反射シート１１の後面の内側領域を押圧することができるので、反射シート１１の内側領域が後方に離間するのを抑制することができる。また、表示パネル支持部材４の第１凹部４１により反射シート１１の後面の内側領域を押圧することができるので、反射シート１１を押圧するための専用の部材を別途設ける必要がない。 In the present embodiment, as described above, the display panel support member 4 is depressed toward the reflection sheet 11 so as to press the inner area (shaded portion A in FIG. 9) excluding the vicinity of the outer peripheral portion of the rear surface of the reflection sheet 11. Unlike the case where only the vicinity of the outer peripheral portion of the reflective sheet 11 is pressed, the first concave portion 41 of the display panel support member 4 causes the reflective sheet 11 to have the first concave portion 41 (shaded portion B in FIG. 8). Since the inner area of the rear surface can be pressed, it is possible to suppress the inner area of the reflection sheet 11 from being separated rearward. Moreover, since the inner area | region of the rear surface of the reflective sheet 11 can be pressed by the 1st recessed part 41 of the display panel support member 4, it is not necessary to provide the member for exclusive use for pressing the reflective sheet 11 separately.

また、本実施形態では、上記のように、表示パネル支持部材４の第１凹部４１の前面（図８の斜線部分Ｂ）が、反射シート１１の後面のうち外周部近傍を除く内側領域（図９の斜線部分Ａ）と面接触した状態で、反射シート１１の後面のうち外周部近傍を除く内側領域を押圧することによって、表示パネル支持部材４の第１凹部４１の前面が、反射シート１１の後面のうち外周部近傍を除く内側領域と点接触または線接触する場合と比べて、反射シート１１を押圧する面積を大きくすることができるので、反射シート１１の内側領域が後方に離間するのを確実に抑制することができる。 In the present embodiment, as described above, the front surface (shaded portion B in FIG. 8) of the first recess 41 of the display panel support member 4 is the inner region excluding the vicinity of the outer peripheral portion of the rear surface of the reflection sheet 11 (FIG. 9 in a state of being in surface contact with the hatched portion A), the front surface of the first recess 41 of the display panel support member 4 is brought into contact with the reflection sheet 11 by pressing the inner region excluding the vicinity of the outer peripheral portion of the rear surface of the reflection sheet 11. Compared to the case of point contact or line contact with the inner region excluding the vicinity of the outer peripheral portion of the rear surface, the area for pressing the reflection sheet 11 can be increased, so that the inner region of the reflection sheet 11 is separated backward. Can be reliably suppressed.

また、本実施形態では、上記のように、表示パネル支持部材４の第１凹部４１の前面の反射シート１１の後面と面接触している領域のうちの外縁部に対応する領域の断面形状を、曲面形状に形成することによって、たとえば、表示パネル支持部材４の第１凹部４１の前面の反射シート１１の後面と面接触している領域のうちの外縁部に対応する領域の断面形状が曲面形状ではなくＬ字形状（直角）に形成されている場合と異なり、反射シート１１の後面の表示パネル支持部材４の第１凹部４１の前面と面接触している領域のうちの外縁部に対応する領域近傍が圧迫されるのを抑制することができる。 Moreover, in this embodiment, as mentioned above, the cross-sectional shape of the area | region corresponding to the outer edge part in the area | region which is in surface contact with the rear surface of the reflection sheet 11 of the front surface of the 1st recessed part 41 of the display panel support member 4 is used. By forming the curved surface, for example, the cross-sectional shape of the region corresponding to the outer edge portion of the region in surface contact with the rear surface of the reflection sheet 11 on the front surface of the first recess 41 of the display panel support member 4 is curved. Unlike the case where it is formed in an L-shape (right angle) instead of a shape, it corresponds to the outer edge portion of the area in surface contact with the front surface of the first recess 41 of the display panel support member 4 on the rear surface of the reflective sheet 11. It is possible to suppress the vicinity of the area to be pressed.

また、本実施形態では、上記のように、表示パネル支持部材４の第１凹部４１が反射シート１１の後面のうち外周部近傍を除く内側領域（図９の斜線部分Ａ）を押圧するのに加えて、ヒートシンク１０が反射シート１１の後面のうち外周部近傍を押圧することによって、第１凹部４１とヒートシンク１０とにより、反射シート１１の後面のうちの内側領域（図９の斜線部分Ａ）と外周部近傍との両方が押圧されるので、より確実に反射シート１１を押さえることができる。また、ＬＥＤ光源１７ａから発生した熱を放熱させるヒートシンク１０により反射シート１１の外周部近傍を押圧することができるので、反射シート１１の外周部近傍を押圧するための専用の部材を別途設ける必要がない。 Further, in the present embodiment, as described above, the first recess 41 of the display panel support member 4 presses the inner region (shaded portion A in FIG. 9) excluding the vicinity of the outer peripheral portion of the rear surface of the reflection sheet 11. In addition, when the heat sink 10 presses the vicinity of the outer peripheral portion of the rear surface of the reflection sheet 11, the first recess 41 and the heat sink 10 cause an inner region (shaded portion A in FIG. 9) of the rear surface of the reflection sheet 11. And the vicinity of the outer peripheral portion are pressed, so that the reflection sheet 11 can be pressed more reliably. Moreover, since the heat sink 10 that dissipates the heat generated from the LED light source 17a can press the vicinity of the outer periphery of the reflection sheet 11, it is necessary to provide a dedicated member for pressing the vicinity of the outer periphery of the reflection sheet 11. Absent.
