The present invention relates to a method of manufacturing a liquid crystal display device having a TFT substrate and a counter substrate, and prevents brightness unevenness from being caused by orientation film thickness unevenness. Orientation films for the TFT substrate (10) and the counter substrate (20) are formed by offset printing that is performed to transfer an orientation film material from a printing plate to the TFT substrate (10).The direction in which the printing plate for an offset printing machine rotates during offset printing is the long-axis direction of the TFT substrate (10) in the case of the TFT substrate (10) or the short-axis direction of the counter substrate in the case of the counter substrate. This ensures that brightness unevenness caused by orientation film thickness unevenness is inconspicuous even when the orientation film thickness unevenness is produced during offset printing.
