At low cost, without the diffracted light generated, also provides a retardation film never wavefront aberration occurs.
A first region disposed on a glass substrate, a second region and a third region, the second region and the first region has a uniaxial birefringent in at least a part, the third region has a uniaxial birefringent, the third region, there is disposed between the first region and the second region, said first region wherein the fast axis of the birefringence of the second region are substantially parallel, wherein the fast axis of the birefringence of the third region, the fast axis of the birefringence of said first and said second region to solve the above problems by providing a phase difference plate which is a substantially orthogonal.
