Lighting device, display device and television device

A lighting device comprising:

• a chassis including:
• a rectangular bottom plate having an inner surface;
• and
• side plates projecting at an angle from corresponding edges of the inner surface such that the chassis has an opening on a side opposite to the bottom plate;
• a plurality of light sources arranged in a matrix on the inner surface of the bottom plate of the chassis, wherein the light sources are configured to emit light toward the opening of the chassis;
• and
• a reflector including:
• a bottom portion arranged on the inner surface of the bottom plate of the chassis, the bottom portion including a plurality of through holes through which the light sources extend, respectively;
• at least one first projecting portion projecting from the bottom portion between the light sources that are adjacent to each other, wherein
• the at least one first projecting portion has an elongated ridge-shaped configuration including a first surface and a second surface,
• the first surface projects from the bottom portion at an angle to reflect the light toward the opening of the chassis,
• the second surface projects from the bottom portion at an angle toward the first surface such that a distal end of the first surface and a distal end of the second surface are connected together to reflect the light toward the opening of the chassis, and
• the at least one first projecting portion is arranged parallel to one of long and short edges of the bottom plate of the chassis;
• and
• second projecting portions each projecting from the bottom portion between the adjacent light sources, wherein
• each of the second projecting portions includes a rhombic top surface and side surfaces that extend between the top surface and the bottom portion, and
• the second projecting portions are arranged in a matrix such that the second projecting portions and the light sources are arranged alternately along a longitudinal direction of the at least one first projecting portion.
