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