ABSTRACT:
In order to make the display of an LCD clearer than before, this invention provides an LCD which has a uniform cell gap between two soda lime glass substrates, which can be achieved by providing glass substrates having grooves on the outer surfaces. Further, this invention provides a method for making the same, comprising the steps of: applying a photoresister on the outer surfaces of two soda lime glasses each of which has an indium tin oxide transparent electrode layer or orientation layer; exposing the applied glasses to light through a mask; etching the exposed glasses to produce a pattern on the glasses; etching the patterned soda lime glasses with a hydrogen fluoride solution to produce glasses having grooves.
