Flexible substrate materials and handling method are the key factor for flexible liquid crystal displays (LCDs). A 3.47 inch flexible LCD designed for wearable applications was successfully fabricated using an optical clear fiber-reinforcedplastic (FRP) substrate and a film lamination followed by mechanical peeling process. This is the first flexible liquid crystal display applied for wearable smart device

Colorless polyimide liquid crystal display (CPI-LCD) was successfully fabricated by PI-LCD handling process which contained substrate coating, LCD manufacture and dualsubstrate laser lift-off (LLO) process. Plastic substrate was made by high transmittance CPI material (T > 91%). Total cell thickness without polarizer is less than 25 ȝm.

A special cell structure design using in plastic liquid crystal display (LCD) was successfully fabricated to overcome upper and bottom substrate alignment shift during bending situation. Bending shift for plastic LCD before and after the application of dual substrate photo spacer (PS) design were 66.5 and less than 5 um, respectively.
