ABSTRACT:
A liquid crystal display device of the present invention includes: two substrates facing each other, at least one of the substrates being transparent; electrodes disposed on inside surfaces of the respective substrates; a display medium which is provided between the two substrates and formed of polymer walls containing a polymer as their main component and liquid crystal regions containing liquid crystal as their main component; and a plurality of pixels, wherein the liquid crystal regions are partitioned by the polymer walls and are close to the substrates, portions of the liquid crystal regions close to the substrates being in parallel with the substrates, an interval a between the center of one liquid crystal region and the center of an adjacent liquid crystal region in a direction along the surface of the substrate is within a width of one pixel along the direction, and 80% or more of the intervals a satisfy the relationship: 3b/2>a>b/2, where b is an average of the intervals a.
