A simple model for investigating the optical performance of LCDs with respect to external forces is presented in this paper. Based on the continuum theory of a liquid crystal (LC) under an electric field, the simple model is established by adding the stress energy density term to Gibb’s free energy density. Besides, the change in cell gap due to external forces is also considered. The parameters in the model are determined by comparing the calculated results with the vertical tensile experiment data. After then, the tilting tensile experiment is performed to verify the simple model. In addition, the LC director distribution and optical performance changes are further discussed. The proposed model can help predict the possible change in the optical performance of LCDs in complex environments and save the product costs.
