PCb09 配向膜表面凹凸周期とプレティルトとの相関

抄録

The relationship between pretilt and period of polyimide (PI) surface morphology was investigated, by using cells that the polyimide surfaces have various morphology with constant optical structure. As the result, the pretilt angle monotonically decreased as amplitude of surface roughness increased. The change of pretilt angle was strongly correlated with the wave component with period of 40 nm in the surface morphology. The same tendency observed in case of different structure of PI.
