基板の表面濡れ性を用いた液晶/モノマ混合液の相分離形態制御

Flexible liquid crystal displays (LCDs) are required to keep the cell thickness in a curved state. The polymer walls structure fabricated by the photo-polymerization of monomer materials using a pattern UV irradiation has been proposed to stabilize the cell thickness. However, the pattern UV irradiation using photo-mask has a problem of UV light leakage to the pixel area and degrade the image quality of flexible LCDs. In this study, we have investigated the separation of the polymer walls and liquid crystals by controlling a wettability on the substrate surface instead of the pattern UV irradiation using a photo-mask.
