BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY DEVICE HAVING BACKLIGHT ASSEMBLY

PURPOSE: An LCD device having a backlight assembly is provided to laminate a reflective polarized film on a lower polarizer of an LCD panel, and to laminate a prism sheet on the polarizer, thereby preventing the LCD panel from being easily broken owing to shock and improving glass stability.

Zusammenfassung:	PURPOSE: An LCD device having a backlight assembly is provided to laminate a reflective polarized film on a lower polarizer of an LCD panel, and to laminate a prism sheet on the polarizer, thereby preventing the LCD panel from being easily broken owing to shock and improving glass stability. CONSTITUTION: An LCD panel(210) consists of the first polarizer(212) configured on a top surface and the second polarizer(214) configured on a bottom surface. A reflecting polarized film(200) is adhered to the second polarizer(214) for laminating. The second polarizer(214) selectively transmits a light only having a certain polarized axis among lights supplied to the LCD panel(210). The first polarizer(212) changes the selectively transmitted light into other polarized axis. The reflective polarized film(200) reflects the lights having the selectively transmitted polarized axis and the other polarized axis.
