    • A backlight unit and a liquid crystal display device are provided. The backlight unit includes light emitting diodes; and a plurality of temperature adjusting members which reduce a temperature difference formed by emission of heat of the backlight unit, the heat being caused by a convection current of air in a vicinity of the light emitting diodes and by heat emitted from the plurality of light emitting diodes. The liquid crystal display device includes a plurality of circuit boards which are provided with light emitting diodes; a frame on which the circuit boards are installed; and a plurality of temperature adjusting members provided between the plurality of circuit boards and the frame, wherein the plurality of temperature adjusting members having different heat resistances are arranged according to a temperature distribution of heat emitted from the light emitting diodes such that a uniform temperature distribution is maintained across the display device.
    • 提供背光单元和液晶显示装置。 背光单元包括发光二极管; 以及多个温度调节构件,其减少由背光单元的热量发射形成的温度差,所述热量是由发光二极管附近的空气的对流电流和由多个发光二极管发出的热量引起的 二极管。 液晶显示装置包括设置有发光二极管的多个电路板; 安装电路板的框架; 以及设置在多个电路板和框架之间的多个温度调节构件,其中根据从发光二极管发出的热的温度分布布置具有不同耐热性的多个温度调节构件,使得均匀的温度分布 跨越显示设备进行维护。
