<P>PROBLEM TO BE SOLVED: To suppress display unevenness by reducing deviation of impurity ions adsorbed to a TFT substrate and an opposite substrate even when rubbing processing performed on alignment layers formed on opposite surfaces of both substrates is uneven. Ž<P>SOLUTION: Thin film layers are formed on the TFT substrate 10 and opposite substrate 20 (S1, S11), and alignment layers 16 and 22 are formed on the thin film layers of both substrates 10 and 20 respectively (S2, S12) and subjected to rubbing processing (S3, S13). Then when a potential difference ΔVcom due to variation in common voltage measured by a liquid crystal device 1 completed in advance has a plus value, the alignment layer 16 formed on the TFT substrate 10 is heat-treated at predetermined temperature for a predetermined time based upon the potential difference ΔVcom (S5). Then both substrates 10 and 20 are stuck together with a seal material 31 interposed, and liquid crystal 32 is sealed in a region sectioned by both substrates 10 and 20 and the seal material (S21).
