  • Patent number: 8053767
    Abstract: Provided are a flexible and transparent carbon nano tube (CNT) thin film transistor using a degradable polymer substrate, and a display adapting the CNT thin film transistor. The polymer substrate is formed of a polymer material that is naturally degraded, and a CNT channel, where a semiconductive CNT is dispersed on a transparent organic material, is prepared on the polymer substrate. Source and drain electrodes, where a conductive CNT is ejected on a transparent organic material, are connected to both sides of the CNT channel. A gate, where a conductive CNT is dispersed on a transparent organic material, is disposed on or below the CNT channel, and a gate insulation layer including a transparent organic material is disposed between the CNT channel and the gate.
    Type: Grant
