A ${\mathrm{d}}_{\mathrm{yz}}$orbital has

The nodal planes are the planes defined by the axes in the names with the remaining axes for three of the d-orbitals (${\mathrm{d}}_{\mathrm{xy}}, {\mathrm{d}}_{\mathrm{xz}},$ and ${\mathrm{d}}_{\mathrm{yz}}$), which have electron density between two axis. The xz and yz planes are the nodal planes in the case of ${\mathrm{d}}_{\mathrm{xy}}$.
