Illumination unit and display apparatus using the same

An illumination unit comprising:

• a first reflector;
• a second reflector arranged at either side of the first reflector;
• at least one light source module arranged between the first reflector and the second reflector;
• a cover member for covering the second reflector;
• and
• an optical member arranged between the cover member and the second reflector while facing the first reflector,
• wherein the optical member comprises
• a central region, and
• a peripheral region surrounding the central region, and
• wherein the peripheral region of the optical member has a greater weight than a weight of the central region of the optical member.

A display apparatus comprising:

• a display panel;
• and
• an illumination unit for irradiating light onto the display panel,
• wherein the illumination unit comprises
• a first reflector,
• a second reflector arranged at either side of the first reflector,
• at least one light source module arranged between the first reflector and the second reflector,
• a cover member for covering the second reflector,
• an optical member arranged between the cover member and the second reflector while facing the first reflector,
• a first projection member interposed between the optical member and the cover member, and
• a second projection member interposed between the optical member and the second reflector,
• wherein a distance from the cover member to one side surface of the first projection member is longer than a distance from the cover member to one side surface of the second projection member.
