Title (EN) REFLECTIVE FILM FOR EDGE-LIGHT-TYPE BACKLIGHT, AND LIQUID CRYSTAL DISPLAY BACKLIGHT USING SAME
(FR) FILM RÉFLÉCHISSANT COLORÉ POUR RÉTROÉCLAIRAGE DU TYPE À LUMIÈRE DE BORD, ET RÉTROÉCLAIRAGE D'AFFICHEUR À CRISTAUX LIQUIDES L'UTILISANT
(JA) エッジライト型バックライト用反射フィルム及びそれを用いた液晶ディスプレイ用バックライト
Abstract:
(EN) Provided is a reflective film having excellent reduction of damage to the surface of the reflective film due to rubbing together of a light guide plate and the reflective film, and whereby uneven luminance of an edge-light-type liquid crystal backlight can be reduced. A reflective film for an edge-light-type backlight, having a particle-containing layer containing spherical particles on at least one side of a substrate film, and satisfying conditions (i) and (ii). (i): A compression-displacement curve of the spherical particles has at least two inflection points including a first inflection point and a second inflection point. (ii): The second inflection point in the compression-displacement curve is within a range of a displacement rate equal to or greater than 50% of the particle diameter.
(FR) L'invention concerne un film réfléchissant ayant une excellente réduction des dommages causés sur la surface du film réfléchissant dus au frottement conjoint d'une plaque de guidage de lumière et du film réfléchissant, et grâce auquel une luminance irrégulière rétroéclairage de cristaux liquides de type à lumière de bord peut être réduite. Un film réfléchissant pour un rétroéclairage de type à lumière de bord comprend une couche contenant des particules qui contient des particules sphériques sur au moins un côté d'un film de substrat, et satisfait aux conditions (i) et (ii). (i) : Une courbe de compression-déplacement des particules sphériques comprend au moins deux points d'inflexion comprenant un premier point d'inflexion et un second point d'inflexion. (ii) : Le second point d'inflexion de la courbe de compression-déplacement se situe dans une plage d'une vitesse de déplacement supérieure ou égale à 50 % du diamètre de particule.
(JA) エッジライト型液晶バックライトの輝度ムラ低減を図るとともに、導光板と反射フィルムが擦れ合うことにより発生する反射フィルム表面ダメージ低減に優れる反射フィルムを提供する。基材フィルムの少なくとも片面に球状粒子を含有する粒子含有層を有し、次の(i)および(ii)を満たす、エッジライト型バックライト用反射フィルム。(i)前記球状粒子の圧縮変位曲線が第1変曲点および第2変曲点の少なくとも2つの変曲点を有すること(ii)前記圧縮変位曲線において粒子径の50%以上の変位率の範囲内に第2変曲点を有すること
