Display device and manufacturing method thereof

摘要

The present invention is to reduce display unevenness in a display device caused by dispersion of energy density of a laser beam. It is difficult for a periodical pattern to be recognized as display unevenness in display image. The display device of the present invention can visually reduce the display unevenness in the display image by utilizing the visual advantage described above. The display device can be manufactured using a TFT array substrate in which electric characteristic of plural TFTs arranged in a line in the minor axis direction of an linear shaped laser beam periodically fluctuates depending on the place in which each TFT is formed.
