1. A reflective transmission type thin film transistor liquid crystal display (TFT LCD) comprising:

  • a substrate;

    a thin film transistor formed on said substrate and including a source electrode;

    a passivation layer formed over said substrate and having a first contact hole exposing the source electrode;

    a transmissive pixel electrode formed on the passivation layer and connected to a source electrode of the source region through a contact hole;

    a reflective pixel electrode formed on the passivation layer and connected to the source electrode of the source region through a contact hole; and

    a buffer layer formed between the transmissive pixel electrode and the reflective pixel electrode wherein a pixel area of the TFT LCD has a transparent area excluding the reflective pixel electrode and a reflective area including the reflective pixel electrode.
