Light source assembly, display apparatus having the same and method of manufacturing the same

A light source assembly comprising:

• a substrate extending in a first direction;
• and
• a plurality of light source parts arranged in the first direction, on the substrate, provided in plural,
• wherein among the plurality source parts arranged on the substrate, each light source comprises:
• a light source which is on the substrate and generates light;
• a first reflecting element on the substrate, provided in plural to be disconnected from each other along the substrate and comprising:
• a first area, and a second area adjacent to the first area, and
• a plurality of beads which is in the second area and diffuses the light in the second area;
• a first opening which is defined in the first reflecting element and exposes the light source;
• and
• a lens which is on the light source and the first reflecting element, and diffuses the light.

A display apparatus comprising:

• a liquid crystal display panel which displays an image;
• a light source assembly which generates and supplies light to the liquid crystal display panel, and is under the liquid crystal display panel;
• a reflecting sheet between the liquid crystal display panel and the light source assembly, and a plurality of lens openings defined in the reflecting sheet;
• and
• a receiving container which receives the liquid crystal display panel, the light source assembly and the reflecting sheet, and comprises a bottom portion, and side walls extending from the bottom portion substantially perpendicular to the bottom portion,
• wherein the light source assembly comprises:
• a substrate which extends in a first direction and is on the bottom portion of the receiving container;
• and
• a plurality of light source parts arranged in the first direction, on the substarte,
• wherein among the plurality of light source parts arranged on the substrate, each light source part comprises:
• a light source which is on the substrate and generates the light, provided in plural;
• a first reflecting element on the substrate, provided in plural to be disconnected from each other along the substrate, and a first opening which is defined in the first reflecting element and exposes the light source;
• a second reflecting element which is on the first reflecting element, provided in plural to be disconnected from each other along the substrate, and a second opening which is defined in the second reflecting element and exposes the light source, wherein the second reflecting element is smaller than the first reflecting element in a plan view;
• and
• a lens which is on the light source and the second reflecting element, and diffuses the light from the light source, and
• wherein the lens openings of the reflecting sheet respectively correspond to the light source parts of the light source assembly.

A method of manufacturing a display apparatus comprising:
