We demonstrated a single-substrate polymer-stabilized blue phase liquid crystal (PSBP LC) display using a bar-coating technique. The BP temperature range and the electro-optical (EO) properties of PSBP LC cells fabricated on a single-substrate of glass, polycarbonate (PC) and polyethylene terephthalate (PET) were investigated. It was found that PSBP LC cells fabricated on the single-substrate of glass, PC, and PET exhibited a narrower BP temperature range in comparison with the conventional PSBP LC cell. This is necessary to improve the mechanical stability, the thermal stability and the EO performance of the single-substrate PSBP LC cells.
