Liquid crystal antenna substrate and manufacturing method thereof, and liquid crystal antenna and manufacturing method thereof

A manufacturing method of a liquid crystal antenna substrate, comprising:

• 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;
• providing a liquid crystal material at a position corresponding to the conductive pattern;
• and
• performing an exposure process on the liquid photo-curable material from a side of the base substrate away from the conductive pattern by using the conductive pattern as a mask,
• wherein a portion of the liquid photo-curable material not corresponding to the conductive pattern is cured to form spacers;
• the manufacturing method further comprises:
• removing all of a portion of the liquid photo-curable material that is uncured after performing the exposure process from the side of the base substrate away from the conductive pattern by using the conductive pattern as a mask;
• wherein the forming the conductive pattern on the base substrate comprises forming bent conductive lines on the base substrate, and an orthographic projection of the bent conductive lines on the base substrate is not overlapped with the orthographic projection of the spacers on the base substrate, and the orthographic projection of the bent conductive lines on the base substrate abuts against the orthographic projection of the spacers on the base substrate to occupy a complete area.
