Abstract
In this paper, we proposed the novel hybrid guest-host liquid crystal display using the negative charged black particles in order to improve the low contrast ratio. We designed patterned electrode in order to switch the charged particle to the opposite electrode and improved the electro-optical characteristics by optimize the mixture of guest materials. In Comparison with the Heilmeier Guest-Host mode, proposed hybrid guest-host structure showed 80% reduction of transmittance in dark state, and the performance was examined by comparing contrast ratio.
