Abstract:
A method of manufacturing a liquid crystal display having a thin film transistor including a gate electrode extending from a gate line, a first insulation layer covering the gate electrode, a semiconductor layer over the first insulating layer, a source electrode extending from a data bus line and connected to a portion of the semiconductor layer through an ohmic contact layer, a drain electrode connected to another portion of the semiconductor layer through an ohmic contact layer, and a second insulation layer covering the semiconductor layer, the method comprising the steps of:performing a surface-treatment on a surface of the semiconductor layer; andforming the second insulation layer made of an organic material on the treated surface of the semiconductor layer,wherein the step of performing a surface-treatment and the step of forming the second insulating layer are performed in such a way as to provide a stable bond structure substantially free from bonding defects at an interface between the semiconductor layer and the second insulation layer so that detachment of the second insulation layer from the semiconductor layer is prevented and a stable ON-characteristic of the thin film transistor is obtained.
