Display apparatus and backlight unit thereof

A display apparatus comprising:

• a frame;
• a plurality of light emitting diode packages regularly arranged on the frame;
• and
• an optical part disposed above the plurality of light emitting diode packages and comprising a display panel and at least one of a phosphor sheet and an optical sheet,
• wherein each of the light emitting diode packages comprises:
• a light emitting diode chip;
• a molding part covering an upper surface and side surfaces of the light emitting diode chip, the molding part including a transparent material to transmit light emitted from the light emitting diode chip therethrough;
• and
• a reflector disposed on the upper surface of the light emitting diode chip and contacting the upper surface of the light emitting diode chip, the reflector comprising a distributed Bragg reflector including alternately stacked layers having different indices of refraction to reflect at least part of light emitted from the light emitting diode chip, and
• wherein the molding part has a width from one of the side surfaces of the light emitting diode chip to a side surface of the molding part which is 1.5 times to 4 times greater than a thickness of the molding part from the upper surface of the light emitting diode chip to an upper surface of the molding part.
