LCD DEVICE AND LIGHT GUIDE PANEL USED FOR THE SAME

摘要

PURPOSE: An LCD device and a light guide panel used for the same are provided to prevent lowering of luminance of a backlight assembly by improving structures and manufacturing methods of a light guide plate for forming the backlight assembly and a reflection sheet formed on a bottom face of the light guide plate. CONSTITUTION: A plurality of V-shaped groove(155) of a V-CUT type is formed to a horizontal direction of a lamp(55) on a bottom face of a light guide plate(150). A beam emitted from the lamp(55) is reflected vertically by an incline plane of the V-shaped groove(155). A reflective layer(170) is formed on a bottom face of the light guide plate(150) by using a vacuum deposition method. The beam passing through the V-shaped groove(155) is reflected vertically by the reflective layer(170).
