Claim:
A credit card, comprising: a light reflective substrate with a light reflective surface; and a latent image formation layer, the latent image formation layer containing a liquid crystalline polymer material and provided on the light reflective surface, wherein said latent image formation layer comprises at least one oriented portion in which chains of the liquid crystalline polymer material are orientationally arranged in a single direction substantially parallel to a major surface of the latent image formation layer, and at least one non-oriented portion in which an orientation degree of the chains of the liquid crystalline polymer material is lower than an orientation degree of the chains in the oriented portion, wherein said at least one oriented portion and said at least one non-oriented portion constitute a latent image which is unrecognizable by a direct visual observation of the credit card, and wherein said credit card is configured to visualize the latent image by arranging a polarizing member at an observer side close to the latent image formation layer.
