Abstract:
1. A stereoscopic image recognition apparatus comprising: a liquid crystal display device including a liquid crystal cell and a pair of polarizing plates on both sides of the liquid crystal cell; and a time divisional image display interception device including a polarizer, a liquid crystal encapsulation body, a λ/4 plate A, and a λ/4 plate B, wherein the λ/4 plate A is disposed on a visible side of the liquid crystal encapsulation body in the time divisional image display interception device, the λ/4 plate B is disposed on a liquid crystal display device side of the polarizer in the time divisional image display interception device, an angle formed by an absorption axis of a display side polarizer and a slow axis of the λ/4 plate A is 45° or I 35°, the λ/4 plate A and the λ/4 plate B include a transparent support, an alignment film, and an optically anisotropic layer containing a discotic liquid crystal compound, the discotic liquid crystal compound in the optically anisotropic layer is aligned substantially perpendicular to a plane of the optically anisotropic layer, and a polarizer of the display side polarizing plate in the liquid crystal device, the transparent support of the λ/4 plate A, the alignment film of the λ/4 plate A, and the optically anisotropic layer of the λ/4 plate A are arranged toward the visible side in this order.
