Low-Voltage Driven Reflective-Type Flexible Display Devices with Micro-Structured Inner Reflectors and Pillar-Shaped Spacers

초록

We report theoretical and experimental results for high performance reflective flexible ferroelectric liquid crystal displays (FLCDs). For the improvement of electro-optical and mechanical properties of the displays, structure of reflector, optimum cell-gap, and density of pillar-type spacer were systematically investigated. Additionally, photo-defined cusp-shape reflector was built on the bottom substrate to increase optical reflectance and mechanical stability. Based on the experimental results the fabricated flexible FLCD with cell-gap of 1.8 mu m and spacer density of 8% have shown the contrast ratio of more than 4.5:1 at 3 similar to 5 V driving voltage in reflective mode.
