1. A liquid crystal display device, comprising:

  • a first substrate;

    a second substrate;

    a liquid crystal layer interposed between the first and second substrates; and

    a plurality of picture-element regions for providing display,wherein;

    each of the plurality of picture-element regions has a transmission region for providing display in a transmission mode by using light incident through the first substrate, and a reflection region for providing display in a reflection mode by using light incident through the second substrate,the second substrate comprises a transparent substrate and a color filter layer provided in the transmission region and the reflection region,a thickness of the color filter layer in at least a part of the reflection region is smaller than a thickness of the color filter layer in the transmission region,at least in the reflection region of one or more of the picture-element regions, the second substrate includes a plurality of spaced apart transparent dielectric layers between the transparent substrate and the color filter layer, andthe plurality of transparent dielectric layers have a light-diffusing function.
