Abstract: In this work, we studied the alignment stablity of the ULH mode by controlling pretilt angle continuously. To control the pretilt angle, we stacked the vertical alignment layer onto the planar alignment layer. In a chiral nematic LC mode, the Grandjean texture was observed in the planar alignment layer, on the other hand, the ULH texture was observed in the intermediate and vertical alignment layers. As a result, in the higher pretilt conditions, the better stable ULH texture was obtained. However, we found that the optic axis of the ULH texture was uncontrollable in the vertical alignment layer
