<P>PROBLEM TO BE SOLVED: To provide a retardation element capable of reducing ghosts caused by optical anisotropy of a base film, and to provide a cisplay device with the retardation element. <P>SOLUTION: The base film 31 consists of a thin resin film having optical anisotropy. The slow axis AX3 of the base film 31 is oriented in the vertical direction being the direction intersecting with the slow axis AX1 of a right-eye region 32A of the retardation element 30 and the slow axis AX2 of a left-eye region 32B thereof. Each of the slow axes AX1 and AX2 is oriented in the direction intersecting with the slow axis AX3 of the base film 31 at the angle larger than 45°. <P>COPYRIGHT: (C)2010,JPO&INPIT |
