Abstract
[화학식 1]
MMA-PMI-BA
여기서, MMA는 메틸 메트아크릴레이트(Methyl Methacrylate) 단위, PMI는 페닐 말레이 이미드(Phenyl Male Imide) 단위, BA는 부틸 아크릴레이트(Butyl Acrylate) 단위를 나타낸다.
[수학식 1]
Ro = (nx- ny) ×d,
Rth = (nx + ny)/2-nz ×d
상기 수학식 중, nx는 필름면 내의 지상축 방향의 굴절률을, ny는 지상축에 직교하는 방향의 굴절률을, nz는 필름 두께 방향의 굴절률을, d는 필름의 막 두께(nm)를 각각 나타낸다.
