摘要： A ceramic filter for using in making liquid crystal display elements includes a plurality of rectangular apertures adapted to permit glass spacers having the size no more than a predetermined size to pass therethrough and a method thereof, capable of selecting easily glass spacers of a uniform size according to the use of the ceramic filter and of preventing glass spacers from lumping together by mixing them in a diluted solution and then pouring a liquid crystal orientation solution in the mixture, and of providing a uniform cell gap and a uniform ground color. It is possible to avoid entering of ionic materials by virtue of the use of ceramic filter, thereby providing a uniform cell gap.
