Display apparatus and light source device thereof

A display apparatus comprising:

• a light source device configured to output surface light;
• and
• a liquid crystal panel configured to block and transmit the output surface light, wherein the light source device comprises:
• a reflective sheet through which a through hole is formed;
• and
• a light source module exposed through the through hole, and comprising:
• a substrate on which the reflective sheet is disposed;
• a light emitting diode disposed on a first portion of the substrate, the first portion corresponding to the through hole;
• an optical dome covering the light emitting diode and comprising silicon;
• a first light pattern disposed on a second portion of the substrate and completely inside the through hole, the second portion being exposed through the through hole;
• and
• a second light pattern provided on a third portion of the substrate, the second light pattern being disposed completely inside the through hole and outside of the optical dome, the third portion being exposed through the through hole, and the second light pattern comprising a material different from a material of the first light pattern.
