In one embodiment of the present invention, an optical device is manufactured by printing a pixel, wherein said method includes deciding plural discharging positions inside each pixel of the optical device, arranging these plural discharging positions on different positions in lateral direction of the pixel respectively, specifying each of the plural nozzles by a natural number n counted sequentially from the end of the ink jet head, defining a surplus as b when dividing the natural number n with the repetitive number a (b is an integer satisfying: 0&#x2266;b&#x2266;a&#x2212;1), corresponding the surplus b to each of the plural nozzles, repeating a unit step of discharging an ink from nozzles corresponding to the surplus b, finding 'discharge coefficient' by measuring unevenness of ink discharging and changing the number of times of ink discharging.
