A display device manufacturing method including arraying pixels 20 comprising plural sub-pixels with different light-emitting colors in two intersecting directions on a flexible substrate 12 by patterning plural sub-pixels 14, 16, 18 with different light-emitting colors onto the flexible substrate 12, wherein patterning of the sub-pixels is performed such that from the two directions of pixel array, the plural sub-pixels with different light-emitting colors are arrayed within the pixels in a rows along the direction X with the smaller substrate dimensional change ratio.
