Abstract

We demonstrate an optically compensated bend (OCB) cell with pixel-isolating polymer wall. The polymer wall is formed by anisotropic phase separation of LCs and UV-curable polymer. The fabricated cell is initially in ${\pi}-twisted$ state so that it shows uniform and fast bend transition without any transition nucleus. The proposed cell has lower driving voltage than conventional OCB cell. Also, the polymer wall provides mechanical stability, hence preventing distortion of display image from external pressure.
