Film laminate, smart window including the same, and method for manufacturing the smart window

Abstract

Disclosed is a film laminate including: an optical laminate; and a gap layer formed at ends of the optical laminate and including a polyvinyl butyral (PVB) film, wherein the thickness of the gap layer is larger than the thickness of the optical laminate. By providing a structure in which the gap layer thicker than the optical laminate is formed in a pillar shape at ends of the optical laminate so as to minimize the pressure applied to a liquid crystal layer during glass bonding, the uneven distribution of liquid crystals due to the fluidity thereof does not occur, and thus the occurrence of liquid crystal mura may be prevented.
