Paper Abstract

Gray scale was obtained with a ferroelectric liquid crystal (FLC) cell in which the twisted state of FLC molecules is gradually unwound by an applied voltage. The cell has an extinction ratio of 60 at 632. 8 nm and a response time of 300 jtsec. A spatial light modulator (SLM) with 256 x 256 pixels was fabricated by incorporating the FLC cell with an amorphous silicon thin film transistor array. This offers us a promising technology to realize a FLC-SLM with gray scale a fast frame time of 300 psec and a pixel number as large as 1000 x 1000.
