광반도체 소자를 밀봉한 상태에 있어서, 외부로부터의 충격을 받은 경우라도 광반도체 소자가 발하는 광의 색감이 변화하기 어려운 광반도체 소자 밀봉용 시트를 제공한다. 광반도체 소자 밀봉용 시트(1)는, 기판(6) 상에 배치된 1 이상의 광반도체 소자(7)를 밀봉하기 위한 시트이다. 광반도체 소자 밀봉용 시트(1)는, 기재 필름(2)과, 기재 필름(2)에 적층된 착색 점착제층(4)을 구비한다. 기재 필름(2)의 25℃에 있어서의 저장 탄성률 E(MPa), 두께 h(mm), 기재 필름(2)의 상부 에지로부터 중립축까지의 거리를 λ(mm)로 했을 때, 기재 필름(2)은 E×(h-λ)3≥1.0을 충족한다. The invention relates to a sheet for sealing an optical semiconductor element and a display body. Provided is a sheet for sealing an optical semiconductor element in which the color tone of light emitted by the optical semiconductor element is not easily changed even when subjected to an external impact in a state in which the optical semiconductor element is sealed. A sheet (1) for sealing an optical semiconductor element is used for sealing one or more optical semiconductor elements (7) disposed on a substrate (6). A sheet (1) for sealing an optical semiconductor element is provided with a base film (2) and a colored adhesive layer (4) laminated on the base film (2). When the storage modulus of the base film (2) at 25 DEG C is E (MPa), the thickness is h (mm), and the distance from the upper edge of the base film (2) to the neutral axis is [lambda] (mm), the base film (2) satisfies E * (h-[lambda]) 3 ≥ 1.0.
