1=1 μm, H=3 μm and W=3 μm, L=4 μm, W
1=1 μm, H=3 μm of two curves are known); When exterior electrode width and electrode gap one timing, along with broadening of projection, driving voltage decreases thereupon, (contrast W=2 μm, L=4 μm, W but transmitance declines by a big margin thereupon
1=1 μm, H=3 μm and W=3 μm, L=4 μm, W
