The present invention provides a display body in which color shift is unlikely to occur and which has high brightness. According to the present invention, a display body (1) comprises: a substrate (2); a plurality of optical semiconductor elements (3a to 3c) arranged on the substrate (2); and a sealing resin layer (4) which seals the plurality of optical semiconductor elements (3a to 3c). The sealing resin layer (4) includes a colored layer (41) and a non-colored layer (42) in order from an optical semiconductor element (3a to 3c) side. In a vertical cross-section with respect to a surface of the substrate (2) which passes through the center of gravity (G_A) of the optical semiconductor element (3a) and the center of gravity (G_B) of the optical semiconductor element (3b) adjacent to the optical semiconductor element (3a) within the same pixel (3), a cross-sectional area (S1) of the colored layer (41) located on a front surface side of the optical semiconductor element (3a) is smaller than a cross-sectional area (S2) of the colored layer (41) located between the optical semiconductor element (3a) and the optical semiconductor element (3b). 본 발명은, 컬러 시프트가 일어나기 어렵고, 또한 휘도가 높은 표시체를 제공한다. 표시체(1)은, 기판(2)과, 기판(2) 상에 배치된 복수의 광반도체 소자(3a 내지 3c)와, 복수의 광반도체 소자(3a 내지 3c)를 밀봉하는 밀봉 수지층(4)을 구비한다. 밀봉 수지층(4)은, 광반도체 소자(3a 내지 3c)측으로부터 순서대로 착색층(41) 및 비착색층(42)을 포함한다. 광반도체 소자(3a)의 무게 중심(GA)과, 광반도체 소자(3a)와 동일 픽셀(3) 내에서 인접하는 광반도체 소자(3b)의 무게 중심(GB)을 통과하는, 기판(2) 표면에 대한 수직면 단면에 있어서, 광반도체 소자(3a)의 정면측에 위치하는 착색층(41)의 단면적(S1)은, 광반도체 소자(3a) 및 광반도체 소자(3b) 사이에 위치하는 착색층(41)의 단면적(S2)보다도 작다.
