2.3.2 The Mechanical and Stability of the Transparent Polymer
Electrode

The polymer electrode has better bending strength than ITO-PET as shown in
Table 3 . The variation of the sheet resistance of the film is less than ITO-PET. The
ITO-PET is vulnerable to the bending stress: extensive cracks are developed if the
ITO surface is subject to just one time excessive bending stress. Thus in the case of
PLED, we could not observe the light emission from the device after the several
bending cycles.
