Claim 0:
1. A liquid crystal display device, comprising:
a first substrate;
a second substrate facing the first substrate and located closer to an observer than the first substrate; and
a liquid crystal layer provided between the first substrate and the second substrate, and further including
a plurality of pixels arrayed in a matrix shape including a plurality of rows and a plurality of columns,
the liquid crystal display device configured to perform display in a twisted vertical alignment mode in which liquid crystal molecules are in a vertical alignment state when no voltage is applied to the liquid crystal layer and the liquid crystal molecules are in a twisted alignment state when a predetermined voltage is applied to the liquid crystal layer,
wherein each of the plurality of pixels includes a reflective region in which display is performed in a reflection mode,
the first substrate includes a reflective electrode including a portion located in the reflective region, and a first vertical alignment film located on a surface on the liquid crystal layer side,
the second substrate includes a second vertical alignment film located on a surface on the liquid crystal layer side,
the liquid crystal layer includes a liquid crystal material having negative dielectric anisotropy, and a chiral agent,
the reflective electrode includes silver or a silver alloy,
at least one of the first vertical alignment film and the second vertical alignment film is a photo-alignment film including an alignment film material having a reaction wavelength with respect to light of at least 313 nm, and
the reflective region includes a plurality of liquid crystal domains in which reference alignment azimuths of liquid crystal molecules are different from each other.
