Abstract: A transparent substrate with optical compensation ability comprises polyimide having the following chemical formula: wherein A and A? are cyclic aliphatic or aromatic compounds, B and B? are cyclic aliphatic or aromatic compounds. In particular, the refractive index of the transparent polyimide is nx=ny>nz, that is, it has ability of adjusting the negative type c-plate phase difference, wherein 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.

Abstract: A method of fabricating a flexible thin film transistor array substrate is provided. First, a rigid substrate is provided, and a polymer material layer is coated on the rigid substrate. Then, an insulating layer is coated over the polymer material layer by a spin coating process. The insulating layer covers the sides of the polymer material layer. Thereafter, a thin film transistor array is formed over the insulating layer. Then, the polymer material layer having the thin film transistor array is separated from the rigid substrate.
