Title:
BACK LIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME
Document Type and Number:
WIPO Patent Application WO2004006002
Kind Code:
A3
Abstract:
A backlight assembly (600) of the present invention includes a light guide plate (LGP), a light reflecting member (200), two lamps (300). The LGP includes a light incidence face (136), a light reflecting face (150). and a light exiting face (160). The light reflecting face (150) reflects a first light toward the light exiting face (160) to transform the first light into a second light. The second light exits from the light exiting face (160). A width of the light incidence face (136) is a first distance. The light reflecting member (200) covers the light incidence face (136) so as to form a receiving space (240). The two lamps (300) are disposed in the receiving space (240). The two lamps (300) are spaced apart from each other by a second distance. A sum of diameters of the two lamps and the second distance is longer than the first distance. According to the present invention, a weight, a volume and a thickness of the LGP is reduced.
