Abstract
A method of manufacturing a liquid crystal display apparatus includes forming at least one assembly for forming a plurality of finished liquid crystal display apparatuses, by opposing two glass substrates to have a space therebetween and sealing a periphery of the space between the two glass substrates by an outer peripheral seal member. Outer surfaces of the two glass substrates are etched by soaking the assembly in an etching solution within an etching bath while maintaining a temperature and a concentration of the etching solution within the etching bath at a substantially constant temperature and at a substantially constant concentration. The etched outer surfaces of the glass substrates are flattened by polishing the outer surfaces of the glass substrates.
