  • Publication number: 20060267891
    Abstract: A liquid crystal device includes first and second substrates which are arranged so as to face each other with a liquid crystal layer interposed therebetween, and first and second electrodes which are provided on the first substrate facing the liquid crystal layer. The liquid crystal layer is driven by electric fields generated between the first and second electrodes. A reflective display region for reflective display and a transmissive display region for transmissive display are provided in each of a plurality of subpixel regions. A liquid-crystal-layer-thickness-adjusting layer is provided in at least the reflective display region so as to vary the thickness of the liquid crystal layer in the subpixel region. A gap between the first and second electrodes in a main direction of an electric field in the transmissive display region is narrower than a gap between the first and second electrodes in a main direction of an electric field in the reflective display region.
