Abstract STN LCDs on plastic film substrates for mobile communication devices have been researched and developed at KETI in KOREA. The plastic film substrate is so weak to heat and pressure that its fabrication process is limited to 110°C. The ITO electrode layer was deposited on the bare plastic film substrate by rf‐magnetron sputtering. And in order to maintain uniform cell gap and press on the plastic film substrate without deformation of substrate surface, we utilized newly invented jig and fabrication process. Electro‐optical characteristics are better than or equivalent to those of typical glass LCDs though it is thinner, lighter‐weight, and more robust than glass LCD.
