We created a no-bias-bend (NBB) pi cell on a blended polyimide (PI) layer with intermediate pretilt angles using the ion-beam method. Various pretilt angles were easily obtained depending on the concentration of homeotropic PI. The plot of surface tension corresponded to the variation of the pretilt angle. We also observed a uniform alignment of the liquid crystals on the blended PI layer. The NBB pi cell had a low threshold voltage of 0.9 V and a fast response time of 5.4 ms.
