Abstract: A display device manufacturing method includes annealing a display substrate by irradiating a laser to the display substrate in different energy values, measuring a transmittance of the annealed display substrate, and determining an optimal crystallization value of the display substrate based on the transmittance, wherein the determining of the optimal crystallization value includes calculating an absorbance of the display substrate for each energy value of the laser based on the transmittance, calculating a band gap energy of the annealed display substrate for each energy value of the laser based on the absorbance, and determining an energy value of the laser corresponding to a minimum value of the band gap energy as the optimal crystallization value. Also provided is a display device manufacturing apparatus that may implement the manufacturing method.
