| 摘要 |
An optical device such as an LCD has a package of optical films positioned between a backlight and a display panel for enhancing the optical performance of the device. The package of optical films includes a first layer and a third layer and a second layer disposed between the first and third layers. The second layer is smaller than the first layer, so that the second layer covers a first region of the first layer but not a second region of the first layer. The third layer is attached to the second region of the first layer. In some embodiments the first layer has a structured surface facing the second layer. In other embodiments, the second layer has a structured surface facing the third layer. In other embodiments, both the first and second layers have structured surfaces facing the third layer.
