There are provided an optical element resin composition, an optical element, and a projection screen that, even upon the application of pressure to the surface of a lens in the optical element, do not cause collapse of the shape of the lens and, even when the shape of the lens has been collapsed, enable the collapsed shape to be immediately returned to the original shape, and can ensure good quality (that is, have high friction resistance). The optical element resin composition is a resin composition for constituting an optical element, which has a glass transition temperature of 5 to 36 DEG C and an equilibrium modulus of elasticity of 0.859 x 10<8> to 3.06 x 10<8> dyne/cm<2>. <IMAGE>
