摘要：
We present a dynamic light-scattering experiment on a planarly oriented nematic liquid crystal in the presence of a symmetry-breaking electric field applied normally to the cell planes. This experiment gives direct evidence for the critical behavior of the lowest splay fluctuation mode. A detailed theoretical analysis of the dynamics of this mode is worked out and compared with the experimental results.
