Zusammenfassung:	The present invention relates to a light source package and a backlight unit including the same. In a light source package which includes a light emitting part including a light emitting layer disposed between two electrode layers, a light transmitting layer disposed over the light emitting part, and a light conversion sealing part surrounding both side surfaces of the light emitting part and the light transmitting layer and the upper surface of the light transmitting layer, a transreflective type optical member of a certain thickness is arranged between the upper part of the light transmitting layer and the light conversion sealing part or on the upper part of the light conversion sealing part. So, uniform diffusion can be performed on the entire display device even without a light diffusion lens. 본 발명은 광원 패키지 및 그를 포함하는 백라이트 유닛에 관한 것으로서, 2개의 전극층과 전극층 사이에 배치되는 발광층을 포함하는 발광부와, 발광부 상부에 배치되는 광투과층과, 상기 발광부 및 광투과층 양측면과 상기 광투과층 상면을 둘러싸는 광변환 밀봉부로 구성되는 광원 패키지에서, 광투과층 상부와 광변환 밀봉부 사이 또는 광변환 밀봉부 상부에 일정 두께의 반사투과형 광부재를 배치함으로써, 광확산 렌즈 없이도 표시장치 전면에 고른 광확산이 가능하다.
