Title (EN) LIQUID CRYSTAL BACKLIGHT DEVICE
(FR) DISPOSITIF DE RÉTROÉCLAIRAGE À CRISTAUX LIQUIDES
(JA) 液晶バックライト装置
Abstract:
(EN) A liquid crystal backlight device (100) is provided with: a frame (120) that has a first frame (106) and a second frame (105), which form a space; a liquid crystal panel (101) covering an opening (106b); a backlight unit that irradiates the liquid crystal panel (101) with light; an optical sheet (102); a cushion member (110) disposed between the liquid crystal panel (101) and the first frame (106) such that the cushion member surrounds the opening (106b) without a gap therebetween; a cushion member (111) disposed between the first frame (106) and the optical sheet (102) such that the cushion member surrounds the opening (106b) with a predetermined gap therebetween; and a sealing material (113), which is provided on a side surface of the frame (120), said side surface being on the side portion side of the frame when viewed from the front surface side, and which seals a hole communicating the space with the outside.
(FR) La présente invention concerne un dispositif de rétroéclairage à cristaux liquides (100) qui comporte : un cadre (120) possédant un premier cadre (106) et un second cadre (105) qui forment un espace ; un panneau à cristaux liquides (101) recouvrant une ouverture (106b) ; une unité de rétroéclairage exposant le panneau à cristaux liquides (101) à de la lumière ; une feuille optique (102) ; un élément d'amortissement (110) disposé entre ce panneau à cristaux liquides (101) et le premier cadre (106) de telle sorte que l'élément d'amortissement entoure l'ouverture (106b) sans interstice entre eux ; un élément d'amortissement (111) disposé entre ledit premier cadre (106) et la feuille optique (102) de telle sorte que l'élément d'amortissement entoure l'ouverture (106b) avec un interstice prédéfini entre eux ; et un matériau d'étanchéité (113) qui se situe sur une surface latérale du cadre (120), ladite surface latérale se trouvant sur le côté partie latérale du cadre lorsqu'elle est vue à partir du côté surface avant, et qui obture de manière étanche un orifice faisant communiquer l'espace avec l'extérieur.
(JA) 液晶バックライト装置(100)は、空間を形成する第1フレーム(106)及び第2フレーム(105)を有するフレーム(120)と、開口(106b)を塞ぐ液晶パネル(101)と、液晶パネル(101)に光を照射するバックライトユニットと、光学シート(102)と、液晶パネル(101)と第1フレーム(106)との間において、開口(106b)を隙間なく囲んで配置されるクッション部材(110)と、第1フレーム(106)と光学シート(102)との間において、開口(106b)を囲み、かつ、所定間隔を空けて配置されるクッション部材(111)と、前面側から見て、フレーム(120)の側方側の側面に設けられ、空間と外部とを連通する孔を封止する封止材(113)と、を備える。
