Abstract
A liquid crystal display device includes a pair of substrate; a liquid crystal layer that is formed between the pair of substrates, and that is composed of liquid crystal having negative dielectric anisotropy, the liquid crystal being vertically aligned in an initial state; dot regions each having a transmissive display region and a reflective display region; a liquid-crystal-layer-thickness adjusting layer that is provided between the liquid crystal layer and at least one of the pair of substrates to make the thickness of the liquid crystal layer in the reflective display region smaller than the thickness of the liquid crystal layer in the transmissive display region; a color filter layer that includes plural types of colored layers having different colors corresponding to the respective dot regions, and that is provided on at least one of the pair of substrates; and alignment regulators that are provided on an inner surface of at least one of the pair of substrates to regulate the alignment of the liquid crystal in the reflective display regions. In the above-mentioned structure, a colored region having the colored layer formed therein and a non-colored region not having the colored layer formed therein are provided in a portion of the colored layer that is arranged in the reflective display region, and the alignment regulators are arranged so as to overlap the non-colored regions of the color filter layer in the reflective display regions in plan view.
