This paper reports surface treatment effect on liquid crystalline blue phase morphology and electro-optical performances at various temperatures. We have succeeded to achieve homogeneous monodomain blue phase morphology by surface treatment. Operating voltage and hysteresis of the proposed device is greatly reduced compared to the non surface treated cell, owing to dramatic increase in Kerr constant. Uniform mono domain morphology has better electric field withstand capability so that its original texture restored after electric field addressing. [ABSTRACT FROM AUTHOR]
