METHOD FOR MANUFACTURING GLASS SUBSTRATE FOR LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is a method for manufacturing a glass substrate for a liquid crystal display device, wherein frequency of generation of watermarks after removing a liquid such as a detergent with an air jet is significantly reduced in comparison to that in conventional methods. In a washing process, the liquid such as a detergent is sprayed onto the surface of the glass substrate (3) to wash. Thereafter, in a removing process an air jet extending long is supplied from a slit (10g) of the nozzle assembly (10) of an air jetting device (1) onto the surface of the glass substrate (3) to remove the liquid such as a detergent. The air speed of the air jet from the slit (10g) is adjusted so as to be uniform in an extending direction by use of an air speed measuring device (40) and an air speed measuring tool (30).
