We report a flexible transparent display based on a plasma display platform. The test panel was designed to 42-in VGA resolution since the proposed flexible transparent plasma display is targeted for use in large-area and lightweight displays in order to replace windows. A test panel was fabricated with organic materials, with the exception of an electrode and the MgO protective layer. A polyethylene terephthalate (PET) plastic film was used as the substrate. The maximum temperature applied to PET substrates during the test panel fabrication was 60 degrees C. Each inner component had a high transparency of over 90%. The average transmittance of the test panel was 57.5% in the visible spectral range.
