The present invention is configured so that it has a first substrate, a
second substrate, a liquid crystal layer pinched between the first
substrate and second substrate, and a driving unit, wherein a
characteristic of a reflectivity versus an applied voltage is a normally
closed type and a characteristic of a transmissivity versus an applied
voltage is the normally closed type: wherein the first substrate has a
common electrode, and an upside polarization plate and upside phase plate
on an upper surface; wherein the second substrate has a reflective
electrode and transparent electrode connected with an active element, and
a downside polarization plate and downside phase plate on a lower
surface; wherein the liquid crystal layer has a twist angle not less than
40 degrees and not more than 65 degrees; wherein a retardation of the
liquid crystal layer in a reflective display unit is within a range of
not less than 230 nm and not more than 300 nm; and wherein a retardation
of the liquid crystal layer in a transmissive display unit is larger than
the retardation of the liquid crystal layer in the reflective display
unit. Thus, is obtained a display that is more luminous and wider in a
light reproduction range under a wide range of luminous environments
ranging from a dark place to direct sunlight.
