In this research, we have reported a method to realize grayscale operation of SSFLCDs by controlling the threshold voltage of the samples. The control of the threshold voltage is achieved by forming liquid crystalline polymer networks in a FLC cell using a UV curable liquid crystalline monomer. It is found that the threshold voltage of the samples decreases with increasing the concentration of the doped monomer. These results indicate that, if the amount of the polymer network formed in a FLC medium is varied from a region to a region in one pixel, we can get a quasi‐multi‐stable SSFLCD, resulting in a grayscale operation of the device by a passive matrix addressing.
