The invention provides a light-diffusing resin composition capable of realizing high color-rendering and brightness when used in light-diffusing sheets, and a light-diffusing sheet and a light source unit using same. Provided are: a light-diffusing resin composition comprising preferably 1 - 80 mass% of a binder resin (A), preferably 15 - 95 mass% of a light-diffusing agent (B), and preferably 0.0001 - 5 mass% of a trimethine cyanine compound (C) represented by formula (I); and a light-diffusing sheet using said light-diffusing resin composition in the light-diffusing layer. The light source unit is equipped with said light-diffusing sheet and a light source, preferably a white LED. |
