6. Which statement best describes the role of the liquid crystals in a liquid crystal
display (LCD)?
a) The liquid crystals emit light in direct response to an applied voltage.
b) The liquid crystals change the direction of polarization of light in direct
response to an applied voltage.
c) The liquid crystals transmit light in direct response to an applied voltage; the
larger the voltage, the greater their transmission.
d) The liquid crystals change phase (from solid to liquid) in direct response to an
applied voltage.
