<P>PROBLEM TO BE SOLVED: To provide a transparent composite sheet which has reduced optical anisotropy. <P>SOLUTION: The transparent composite sheet includes: a cured product obtained by curing a curable composition; and a glass fiber buried into the cured product. The curable composition includes: first monomers forming a polymer having positive refractive index anisotropy; and second monomers forming a polymer having negative refractive index anisotropy. A difference between the refractive index of the cured product in a wavelength of 589 nm and the refractive index of the glass fiber in a wavelength of 589 nm is ≤0.01, and the in-plane phase difference in a wavelength of 550 nm of the transparent composite sheet in which the polymers are uniaxially oriented along the glass fiber is ≤5 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
