    • PURPOSE: A complex prism sheet and a manufacturing method thereof are provided to reduce a failure due to the entry of foreign materials or scratch in assembling the backlight unit by combining a diffusion layer and a protection layer with the prism sheet. CONSTITUTION: A lower layer(120) is provided. A middle layer(130) is stacked on the upper side of the lower layer and has a plurality of parallel pillar prisms on the upper side thereof. An upper layer(150) is stacked on the upper side of the middle layer and has a light diffusion structure on the upper side thereof. The lower layer, the middle layer, and the upper layer are integrated. An air layer is formed in a valley between the lower side of the upper layer and the prism of the middle layer.
    • 目的:提供一种复杂的棱镜片及其制造方法,以通过将扩散层和保护层与棱镜片组合来减少由于异物进入或组装背光单元而导致的划痕的故障。 构成:提供下层(120)。 中间层(130)堆叠在下层的上侧,并且在其上侧具有多个平行柱状棱镜。 上层(150)层叠在中间层的上侧,并且在其上侧具有光漫射结构。 下层,中间层和上层被集成。 在上层的下侧和中间层的棱镜之间的谷部中形成空气层。
