Abstract
A liquid crystal display device of the invention comprises a transparent substrate a transparent electrode formed on the inner surface of the transparent substrate an alignment layer formed over the transparent electrode a composite formed over the alignment layer and a transparent electrode on the upper surface of the composite The composite comprises a transparent polymer and a liquid crystal droplet The liquid crystal droplet is configured in a substantially hemispherical shape such that a bottom surface of the droplet is in contact with the alignment layer and the remaining surface excluding the bottom surface bulges towards an upper surface of the composite The polymer constitutes the other surface of the composite such that the polymer covers the hemispherical liquid crystal droplets Thus, the invention achieves a liquid crystal display device in which one of the pair of substrates is eliminated and thereby the weight of the device is significantly reduced.
