Abstract
An apparatus for manufacturing a display apparatus includes at least one test table on which a droplet is disposed, at least one profile measurement portion disposed adjacent to the at least one test table to measure a surface profile of the at least one test table and a surface profile of the droplet disposed on the at least one test table, and a controller electrically connected to the at least one profile measurement portion to measure a volume of the droplet from a difference between the surface profile of the at least one test table and the surface profile of the droplet disposed on the at least one test table.
