Abstract
A smart window, and production method therefor, uses glass beads made from glass material instead of a polymer matrix of the conventional smart window. This makes the liquid crystal's size, shape and arrangement constant by placing the liquid crystal outside the glass beads, thereby securing high stability and chemical resistance, avoiding haze, having low operating voltage, and having improved optical, for example, broad variable range of light transmittance between OFF (light impermeable) and ON (light permeable) states.
