The shrinkage of Indium Tin Oxide (ITO) coated Polyethylene Terephthalate (PET) for flexible display applications is investigated using a Thermal Mechanical Analyzer (TMA). The effect of temperature on the resistance of the ITO coated PET was measured using a custom built 4‐wire resistance probe in a temperature enclosure. Thermal shrinkage of the substrate effects the resistance of the ITO and is temperature and substrate dependent. The shrinkage is also anisotropic with the greatest shrinkage in the machine direction. Shrinkage of up to 4% was obtained for samples maintained at 180° C. This shrinkage can greatly influence the reliability of the ITO layer and must be considered during fabrication of flexible displays.
