    • A liquid crystal display device according to the present invention prevents the thermal deformation of a backlight unit by preventing a twist phenomenon due to the difference of a thermal expansion coefficient by minimizing the expansion interference of an LED housing with regard to a cover bottom by dividing the LED housing and changing a coupling hole which is located on the outside of each divided LED housing part into a slot. The liquid crystal display device includes: a liquid crystal panel which outputs an image by forming a liquid crystal layer between a color filter substrate and an array substrate; a plurality of LED arrays which are installed on the lower side of one side of the liquid crystal panel and supply light to the liquid crystal panel; a light guide plate which is installed in the light output direction of the LED array; the LED housing to which the LED array and an LED printed circuit board for driving the LED array are attached; and the cover bottom which is arranged on the lower side of the light guide plate and is coupled to the LED housing by a plurality of coupling units. The LED housing is divided into at least two LED housing parts and the coupling hole which is located on the outside of each divided LED housing part has a slot shape.
    • 根据本发明的液晶显示装置通过防止由于热膨胀系数的差异引起的扭转现象来防止背光单元的热变形,通过将LED壳体相对于盖底部的膨胀干涉最小化, LED壳体,并将位于每个分开的LED壳体部分的外侧上的耦合孔改变成槽。 液晶显示装置包括:液晶面板,其通过在滤色器基板和阵列基板之间形成液晶层来输出图像; 多个LED阵列,其安装在液晶面板的一侧的下侧,并向液晶面板供给光; 导光板,其安装在LED阵列的光输出方向上; 连接LED阵列的LED外壳和用于驱动LED阵列的LED印刷电路板; 以及布置在导光板的下侧上的盖底部,并且通过多个联接单元联接到LED壳体。 LED壳体被分成至少两个LED壳体部分,并且位于每个分开的LED壳体部分的外侧上的耦合孔具有槽形状。

    • PURPOSE: A back light assembly is provided to prevent light from leaking to an adjacent light guide part by using a partition arranged between the light guide parts. CONSTITUTION: A first partition(170a) is arranged in the empty space between a second light guide part(131b) and a first light guide part(131a). A second partition(170b) is arranged in the empty space between a third light guide part(131c) and a second light guide part. A partition(170) and a supporter support a diffusing plate. The light emitted from the lateral surface of a light guide part(131n) runs to an adjacent light guide part. The lateral surface of the partition reflects the light to an upper direction.
    • 目的:提供背光组件以通过使用布置在导光部分之间的隔板来防止光泄露到相邻导光部分。 构成:第一分隔件(170a)布置在第二导光部分(131b)和第一导光部分(131a)之间的空白空间中。 第二分隔件(170b)布置在第三导光部分(131c)和第二导光部分之间的空白空间中。 分隔件(170)和支撑件支撑扩散板。 从导光部(131n)的侧面射出的光向相邻的导光部延伸。 分区的侧表面将光反射到上方。
