    • PURPOSE: An optical assembly, a backlight unit thereof and a display apparatus thereof are provided to enhance the quality of a display image. CONSTITUTION: display panel(100) includes a color filter substrate(110) and a TFT(Thin Film Transistor) substrate(120) that are positioned opposite each other and are attached to each other with a uniform cell gap therebetween. A liquid crystal layer is interposed between the two substrates. The color filter substrate includes a plurality of color filters each including red, green, and blue color filters and generates a red, green, or blue image when light is applied to a display device. The TFT substrate is a substrate on which a plurality of switching elements are formed, and may switch on and off selectively a plurality of corresponding pixel electrodes. The liquid crystal layer comprises the liquid crystal molecules. The arrangement of the liquid crystal molecules varies depending on a voltage difference between the pixel electrode and the common electrode. Hence, light provided by a backlight unit(200) may be incident on the color filter substrate based on changes in the arrangement of the liquid crystal molecules of the liquid crystal layer. An upper polarizing plate(130) and a lower polarizing plate(140) may be respectively positioned on and under the display panel.
