The effects of cell gap on the electro-optical properties of normal-mode polymer-stabilised cholesteric texture (PSCT) have been investigated. In this study, the size of the domain and electro-optical properties of PSCT are analysed as a function of the thickness of the cells. Increasing cell gap helps to improve the contrast ratio, but the threshold voltage would increase simultaneously. The scanning electron microscopy indicates that the polymer networks are tightened with increasing cell gap. A denser polymer network leads to smaller domain size, higher effective electric field and decreased field-off response time.
