1. A reflective type liquid crystal display device, comprising:

  • a first substrate having a plurality of thin film transistors and a plurality of pixel electrodes within a plurality of sub-pixels defined by a plurality of gate and data lines perpendicularly crossing with each other, respectively;

    a second substrate assembled to oppose the first substrate;

    a liquid crystal layer between the first and second substrates;

    a third substrate assembled to oppose the first substrate;

    a plurality of reflective electrodes on the third substrate to correspond to a plurality of the sub-pixels, respectively;

    a counter electrode directly on the first substrate and facing the third substrate; and

    a color filter layer having a plurality of electrophoretic bodies on a plurality of the reflective electrodes wherein each of the electrophoretic bodies is micro-encapsulated with ionic pigment particles,wherein each electrophoretic body has two pigment particles among R, G and B pigment particles, and the color filter layer is formed between the first substrate and the third substrate.
