In order to protect from the electrostatic damage it is common to deposit ITO thin layer on the rear side of CF substrate for the IPS based LCDs. But some polarizer assay of an IPS cell was found losing its protection ability as stored in the humid environment at relatively high temperature while the cell itself did not show the significant change. We clarified the root‐cause and found the quality control factors.
