PURPOSE: To provide a reflection ferroelectric liquid crystal display element of which display is bright and at coloring of display image can be prevented.
CONSTITUTION: A ferroelectric liquid crystal display element is constituted of a pair of substrates 11, 12 formed with electrodes 13, 17, ferroelectric liquid crystal 21 which is arranged between the substrates 11, 12 and oriented according to impressed voltage in an oriented state nearly arranging the liquid crystal molecules in a first direction, in an oriented state nearly arranging the molecules in a second direction, and in an intermediate oriented state arranging the mean direction of the molecules in an optional direction between the first and second directions, dichroic dyestuff 26 added to the ferroelectric liquid crystal 21, a polarising plate 23 of which the transmission axis is set in parallel with the middle line of the first and second oriented directions, and a reflecting plate 27 arranged outside the polarising plate 23. When voltage is impressed between the electrodes 13, 17 to change the oriented state of liquid crystal, the oriented state of the dichroic dyestuff 26 is changed, absorbing rate of linearly polarized light reflected by the reflecting plate 27 and transmitted through the polarising plate 23 by dichroic dyestuff 26 is changed, and hence the transmission factor is changed.
