Backlight assembly and display apparatus having the same

A display apparatus comprising:

• a backlight assembly comprising a light source that generates a light and a first optical member that diffuses the light;
• and
• a display panel receiving the light from the backlight assembly to display an image,
• wherein the first optical member comprises:
• a body including an incident surface to which the tiara is incident and an exit surface facing the incident surface, from which the light exits;
• and
• a first diffusion member disposed on the exit surface to diffuse the light,
• wherein the first diffusion member comprises:
• a single vertex;
• four inclined surfaces, wherein the four inclined surfaces meet at the single vertex, each of the four inclined surfaces is inclined with respect to a flat portion of the exit surface, and each of the inclined surfaces has a curved shape;
• four edges, wherein each of the four edges is disposed between the exit surface and the single vertex and has a curved shape;
• and
• a second diffusion member that has a shape that protrudes from the incident surface to diffuse the light, wherein the incident surface comprises a first area corresponding to an area on the incident surface covered by each point light source and a second area corresponding to an area on the incident surface between two point light sources adjacent to each other, and the second diffusion members are spaced farther apart in the second area than in the first area and a space between each second diffusion member is greatest in a center of the second area and decreases toward the first area.
