ITO electrodes are used broadly for displays. Patterning can cause micro‐cracks and for flexible devices ITO is also often amorphous. Amorphous ITO can be etched by acid containing polymer layers. The combined effect of etching and stress can also lead to stress corrosion cracking. We report on these phenomena.
