Abstract
A backlight assembly and a display apparatus having the backlight assembly are disclosed. A diffusion plate is provided above a plurality of lamps. Diffusion patterns that cause contrast inversion and diffusion patterns that do not cause contrast inversion are arranged on a surface of a diffusion plate, in an alternating manner along a longitudinal direction of the lamps. Thus, a brightness difference between a first area in which the lamps are positioned and a second area between two adjacent lamps is reduced, thereby improving a brightness uniformity of light from the backlight assembly.
