光学片和使用它的背光源单元以及显示器
摘要：
本发明提供一种光学片和使用它的背光源单元以及显示器，在显示器用背光源单元的照明光路控制中使用的光学片(10)中，从照明光(L)的入射侧依次至少具备：光散射层(13)，将照明光向射出面(12)侧散射；粘接层或粘合层(18)；光反射层(14)，将由光散射层(13)散射的光向光散射层(13)侧反射，及透镜片(17)，平坦的背面被固定在光反射层(14)的另一个面上，并在表面上配置有多个单位透镜(16)。在光反射层(14)上，具有与各单位透镜(16)1∶1对应的开口部(15)，并且，粘接层或粘合层(18)的厚度比光反射层薄。
摘要（英）：

The invention provides an optical sheet, and a backlight unit and a display using the same. In the optical sheet (10) which is used for light control illumination in the backlight unit for the display, in order from an incident side of an illuminating light (L), there are provided at least a light scattering layer (13) which scatters the illuminating light (L) toward an outgoing surface (12) side, an adhesion layer or an adhesive layer (18), a light reflection layer (14) which reflects light scattered by the light scattering layer (13) toward the light scattering layer (13) side, and a lens sheet (17) whose flat rear face is fixed to the other side of the light reflection layer (14), and in which a plurality of unit lenses (16) are disposed on the surface. Opening portions (15) corresponding to the respective unit lenses (16) one-to-one are provided to the light reflection layer (14), and thickness of the adhesion layer or the adhesive layer (18) is thinner than that of the light reflection layer (14).
