Reflective display using multiple liquid crystal layers for controlable reflection










Image Number 16 for United States Patent #6147726.

A display device including a composite multi-layer film obtained by alternately laminating films and liquid crystal layers a plurality of times is held between one pair of substrates, and a voltage is applied to the composite multi-layer film to control the reflection factor of the composite multi-layer film. In the display device comprising a composite multi-layer film obtained by alternately laminating films and liquid crystal layers, a voltage being applied to the composite multi-layer film to control the reflection factor of the composite multi-layer film, a refractive factor n.sub.LC1(.lambda.n), in a major axis direction, and a refractive factor n.sub.LC2(.lambda.n), in a minor axis direction, of a liquid crystal used in the liquid crystal layers with respect to light having a predetermined wavelength (.lambda.n), and a refractive factor n.sub.F1(.lambda.n) and a refractive factor n.sub.F2(.lambda.n), in X- and Y-axis directions which are perpendicular to each other in the film surface, of the films with respect to light having the predetermined wavelength (.lambda.n) are set in at least one of combinations of films and liquid crystal layers, which are adjacent to each other, of the films and the liquid crystal layers of the composite multi-layer film, to satisfy the following conditions [1] and [2]:
