Abstract
In a backlight apparatus used in an LCD, in which upper and lower reflective plates are installed under upper and lower transparent plates, respectively. The lower transparent plates and the lower reflective plates introduce light generated by lower light sources in upward directions and the upper transparent plate and the upper reflective plates introduce light generated by an upper light source into those areas, which are not lighted by the lower light sources. This can prevent the formation of dark areas above the lower light sources thereby enhancing the overall uniformity of light.
