Patent ID: 7675063

Claim:
A liquid crystal display device, comprising: a plurality of gate lines and data lines on a first substrate defining a plurality of pixel regions; a thin film transistor within the pixel regions, thin film transistor including a gate electrode on the first substrate, a gate insulating layer on the first substrate, a semiconductor layer on the gate insulating layer, and source and drain electrodes on the semiconductor layer and the gate insulating layer; a passivation layer over the first substrate to cover the thin film transistor; a pixel electrode within the pixel regions; a first TiOx layer on the upper portion of the source and drain electrodes; and a second TiOx layer only directly contact on the upper portion of the semiconductor layer, wherein the source and drain electrodes are contacted with the gate insulating layer, and at least one of the first TiO x layer and the second TiO x layer has a hydrophilic surface.
