Recently the in‐plane switching (IPS) has been heavily exploited in particular for high‐resolution mobile displays. The IPS displays offer good optical quality, however, the complex fabrication and manufacturing cost offers several limitations for their application. On the other hand, electrically suppressed helix ferroelectric liquid crystals (ESHFLC's) because of their intrinsic in‐plane switching offer better solutions with simpler and cheaper fabrication for high‐resolution displays. In this article, the ESHFLC's with fast response time (˜10µs), high contrast ratio (˜ 10k: 1) with low driving voltage (2˜5V/µm) has been achieved through photo alignment technology with acceptable shock stability and without natural diffraction. The ESHFLC's provide good optical quality with simpler fabrication procedures and therefore could secure application for high–resolution displays.
