ABSTRACT:
A vertical alignment liquid crystal layer is sealed between a first substrate having a first electrode and a second substrate having a second electrode, each pixel region has a reflective region and a transmissive region, and a gap adjusting section is provided on one of sides of the first substrate and the second substrate which sets a thickness (gap) d of the liquid crystal layer which controls a phase difference of incident light to the liquid crystal layer so that a gap dr in the reflective region is smaller than a gap dt in the transmissive region. An alignment controller which divides alignment of the liquid crystal within a pixel region is provided in the pixel region on at least one of the sides of the first substrate and the second substrate. It is also possible to optimize by changing the gap in red, green, and blue.
