Abstract
A liquid crystal display device of this invention includes a substrate having a pixel electrode on one major surface, a liquid crystal layer including first and second liquid crystal microcapsule layers sequentially stacked on the pixel electrode of the substrate, and a counter electrode formed on the liquid crystal layer. Each of the first and second liquid crystal microcapsule layers contains a plurality of aspherical liquid crystal microcapsules each formed by encapsulating a liquid crystal material containing a liquid crystal compound and a dichroic dye with a transparent film. The major axes of aspherical liquid crystal microcapsules contained in the first liquid crystal microcapsule layer are aligned in a first direction. The major axes of aspherical liquid crystal microcapsules contained in the second liquid crystal microcapsule layer are aligned in a second direction different from the first direction.
