Abstract: A backlight assembly is provided to suppress a brightness difference between a surrounding region of a light source and the other region by forming grooves on both lateral surfaces of each of a plurality of pole-shaped light-guiding bodies. A backlight assembly is disposed below an LCD panel to supply light to the LCD panel. A bottom chassis is disposed below the backlight assembly to receive the backlight assembly. The backlight assembly comprises a light source(160), a light source-driving circuit board(165), pole-shaped light-guiding bodies(170), a reflecting plate(180), and a diffusing plate. The light-guiding bodies are disposed in parallel. A plurality of grooves are formed on both lateral surfaces of the light-guiding body at regular intervals. In the light-guiding body, the depth of the groove gradually increases from the end portion to the center portion in the longitudinal direction of the light-guiding body. The reflecting plate is positioned below the light-guiding bodies to reflect and refract light effectively.

Abstract: A backlight assembly and an LCD having the same are provided to convert a point light source type light into a line light source type light through a light-guiding pole, thereby improving the efficiency in use of the light. A light-guiding pole(220) is disposed at one side of a light-guiding plate(210). Grooves are formed in a surface of the light-guiding pole, which is opposite to the light-guiding plate. A point light source(230) is disposed at one end of the light-guiding pole to generate light. A reflection plate(240) wraps the light-guiding pole. The reflection plate reflects the light, which is emitted from the light-guiding pole, toward the light-guiding plate. The grooves have 'V' shape. The depth of the grooves gets deeper as the depth comes to the center from both ends of the light-guiding pole.
