Beschreibung
Zusammenfassung:	The present transparent substrate with optical compensation ability possesses comprises polyimide having the following chemical formula: A and A' can be cycloaliphatic compounds or aromatic compounds, and B and B' can be cycloaliphatic compounds or aromatic compounds. In particular, the refractive index of the transparent polyimide is nx=ny > nz, nx represents the lateral refractive index, ny represents the longitudinal refractive index, nz represents the vertical refractive index along the thickness direction, and m and n are between 10 and 10,000.
