    • PURPOSE: Backlight unit and the liquid crystal display apparatus including the same divide 'the semiconductor nanocrystal coated with the first polymer with an excellent affinity' into 'the first polymer and the second polymer which commerciality is superior'. In that way the semiconductor nanocrystal is evenly dispersed within the second polymer. CONSTITUTION: A light conversion layer [light converting layer] (130) is separated from the LED (Light Emitting Diode) light source (110). 'the light which is incoming from the LED light source' is converted into the white light. The white light is emitted to the liquid crystal panel side [LCD (Liquid Crystal Display) panel party]. A light guide plate (120) is located between the LED light source and light conversion layer. The light conversion layer includes the semiconductor nanocrystal [semiconductor nano crystal] and matrix macromolecule [matrix polymer]. The semiconductor nanocrystal is coated with 'the first polymer with an excellent affinity [affination]'. The matrix macromolecule includes 'second polymer with an excellent first polymer and compatibility [consistency]'.
    • 目的:背光单元和液晶显示装置将包含第一聚合物的第一聚合物的半导体纳米晶体与“第一聚合物和第二聚合物具有优异的亲和力”分开。 以这种方式,半导体纳米晶体均匀分散在第二聚合物内。 构成:将光转换层[光转换层](130)与LED(发光二极管)光源(110)分离。 “从LED光源入射的光”被转换成白光。 白光被发射到液晶面板侧[LCD(液晶显示器)面板方]。 导光板(120)位于LED光源和光转换层之间。 光转换层包括半导体纳米晶体[半导体纳米晶体]和基质高分子[基质聚合物]。 半导体纳米晶体涂覆有“亲和力优异的第一聚合物”。 基质高分子包括具有优异的第一聚合物和相容性[稠度]的第二聚合物。
