A coating comprising a polymer layer is disclosed, wherein the polymer layer is a reaction product of a first monomer comprising at least two aromatic acetylene groups and a second monomer comprising at least two cyclopentadienone groups, or Includes cargo. The coating may or may not contain additional crosslinking agents and/or thermal acid generators. The optical thin film made of the coating exhibits a useful refractive index for use as an intermediate layer for matching the refractive index between adjacent layers of a display device; This improves the device output efficiency. |
