Abstract
- The cell gap dependence of the electro-optical properties of reverse-mode polymer-stabilised cholesteric texture has been investigated. In this study, the morphology and electro-optical properties were analysed as a function of the thickness of the cells. The scanning electron microscopy indicates that the polymer networks become tighter with the decrease of cell gap. Increasing cell gap can improve the contrast ratio exponentially, while the threshold voltage increases linearly. The field-off response time increases, which is ascribed to the decreasing elastic force between the polymer network and the LC molecules.
