摘要：

We propose a mechanism for breaking tilted nematic anchorings using an electric field normal to the plates. This breaking is a discontinuous first-order transition, unlike the known second-order breaking of planar anchorings. The elastic coupling of the tilted orientations on both plates is used to initialize the first-order transition. We observe the breaking experimentally by fast (in the mu s range) bulk texture changes, resulting in an additional pi twist in the final state. [S1063-651X(98)05312-4].
