Abstract
A liquid crystal antenna substrate and a manufacturing method thereof, and a liquid crystal antenna and a manufacturing method thereof are provided. The manufacturing method of the liquid crystal antenna substrate includes: forming a conductive pattern on a base substrate; coating a liquid photo-curable material at a side of the conductive pattern away from the base substrate; and using the conductive pattern as a mask to perform an exposure process from a side of the base substrate away from the conductive pattern, a portion of the liquid photo-curable material corresponding to the conductive pattern is cured to form spacers.
