METHOD FOR MEASURING CELL GAP, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY INCLUDING THE METHOD, DEVICE FOR MEASURING THE CELL GAP, AND IN-LINE SYSTEM INCLUDING THE DEVICE
METHOD FOR MEASURING CELL GAP, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY INCLUDING THE METHOD, DEVICE FOR MEASURING THE CELL GAP, AND IN-LINE SYSTEM INCLUDING THE DEVICE
A system for manufacturing liquid crystal displays is provided, which includes: a sealant-applying unit for depositing a sealant on one of the two panels having at least one liquid crystal cell area and a cell gap measuring pattern formed outside of the liquid crystal cell area; a liquid crystal depositing unit for depositing liquid crystal material on the liquid crystal cell area and the cell gap measuring pattern; a substrate-attaching unit for receiving the two panels from the sealant-applying unit or the liquid crystal depositing unit, then conjoining the panels in a vacuum state to complete the manufacture of a liquid crystal panel; and a the cell gap measuring unit for measuring a cell gap between the two panels by detecting the spread areas of liquid crystal material deposited on the cell gap measuring pattern.
