Director tilt angle distribution in VANs for different voltages.
Pretilt vs deposition angle measured by ellipsometry. Mean values are shown as well to give pretilt dependence on deposition angle.
Tilt profile simulated by the elastic theory (dashed lines) and by the sinusoidal model of the ellipsometry software (full lines) vs applied voltage: (a) symmetric cell 50-50 and (b) asymmetric cell 50-80.
Electro-optical parameters for cells with different angles of deposition on the two substrates.
Pretilt in cells with different deposition angles: is the pretilt at the upper alignment substrate; is the pretilt at the lower alignment substrate.
