Abstract: An apparatus for manufacturing a display apparatus includes a movable portion to which a display substrate including a pattern part is attached, wherein the pattern part includes a dummy electrode and an organic functional layer covering the dummy electrode, a processor configured to cause a laser to irradiate the display substrate in a first irradiating process, a measurement unit configured to measure the display substrate to which the laser has irradiated in the first irradiating process, and a controller configured to receive data measured by the measurement unit and control the processor to cause the laser to irradiate the laser in a second irradiating process using at least one different parameter than what was used in the first irradiating process.
