OG exemplary drawing
 
1. A liquid crystal film for automotive glass, the liquid crystal film comprising:
a first base layer;
a first conductive layer;
a microstructured liquid crystal layer;
a second conductive layer; and
a second base layer, wherein:
the microstructured liquid crystal layer is disposed between the first conductive layer and the second conductive layer,
the first base layer and the second base layer are oppositely disposed,
the first conductive layer is attached to the first base layer,
the second conductive layer is attached to the second base layer,
the microstructured liquid crystal layer comprises:
a bottom plate;
a partition plate; and
a liquid crystal mixture, and wherein:
the partition plate comprises sidewalls vertically arranged on the bottom plate, and the bottom plate is attached to the second conductive layer without a liquid crystal mixture therebetween,
the partition plate divides a space between the bottom plate and the first conductive layer into a plurality of polygonal receiving spaces, and
the liquid crystal mixture is positioned in the plurality of polygonal receiving spaces,
wherein a top surface of the sidewalls of the partition plate and the liquid crystal mixture directly contact the first conductive layer,
wherein a planar bottom surface of each of the plurality of polygonal receiving spaces is flat, and
wherein the bottom plate is disposed between the liquid crystal mixture and the second conductive layer and between the partition plate and the second conductive layer.
