Abstract:
1. A method for fabricating a liquid crystal display panel comprising: providing at least two substrates; performing an array process or a color filter process on the substrates; providing an apparatus for forming an alignment film, wherein an alignment film inspecting unit is installed between two lines of rubbing equipment, forming an alignment film on a surface of the substrates that have been array processed or color filter processed; aligning the alignment film-formed substrates at a predetermined angle using the align/turn unit; temporarily waiting the substrates in the buffer before subjecting the substrates to a rubbing process; cleaning the substrates before and after the rubbing process; performing the rubbing process on the cleaned substrates using the two rubbing units; sequentially providing rubbed substrates to the alignment film inspecting unit from the two lines of rubbing equipment in two directions; positioning received substrates on a steam generator in the alignment film inspecting unit, wherein each substrate is positioned to be slanted at a predetermined angle toward the steam generator; applying steam onto a front surface of the substrates on which the alignment film is formed; inspecting the alignment film by observing the substrates from a back surface of the substrates using the alignment film inspecting unit; measuring uniformity of the alignment film by measuring a color change or a light and shade difference; attaching the two substrates which have completely undergone the alignment film inspecting step; and cutting the attached substrates into a plurality of unit liquid crystal display panels.
