Abstract
A method for manufacturing a glass plate using laser etching includes a dipping step for dipping a glass plate, which will be etched, into an etching solution, a patterning step for irradiating laser to the glass plate dipped in the etching solution to form a pattern therein, and a washing step for washing the patterned glass plate. This method allows making a plate with a high aspect ratio and fine line widths in comparison to a conventional plate manufacturing method using photoresist for etching, and also ensures more efficient energy consumption and higher etching efficiency rather than an etching method using laser only.
