| Abstract(in English) | We measured how the response time characteristics of the microstrip-line type PDLC(polymer dispersed liquid crystal) devices. The physical significance of these results was also examined. By varying the PDLC layer thickness with a polymer concentration of 5wt% or 9wr% and keeping the applied electric field constant, we show that increasing the layer thickness causes the decay time to increase and the rise time to decrease. In the case of a polymer concentration of 5wt%, the rise time obtained with a PDLC layer thickness of 100μm is half the value obtained with thickness of 20μm, while the decay time is approximately 3.6 times larger. The layer thickness dependency of the response time characteristics with polymer concentration 9wt% becames the same tendency as 5wt%. However, comparing with the case of 5wt%, the rise time increases and the decay time decreases. |
