Patent ID: 8599325

Claim:
A liquid crystal display device comprising: a TFT substrate; gate lines formed over the TFT substrate; drain lines formed over the TFT substrate; pixel electrodes each formed in a region surrounded by the gate lines and drain lines; protrusions formed below the gate lines, each of the protrusions having an upper surface and at least one inclined side surface; a gate insulating film formed over the gate lines; a semiconductor layer formed on the gate insulating film; drain electrodes formed by the drain lines over the semiconductor layer; source electrodes formed over the semiconductor layer; and channel portions defined by the space between the drain electrodes and the source electrodes, each of the channel portions being formed covering the upper surface and at least one of the at least one inclined side surface of one of the protrusion; wherein the pixel electrode and the source electrode are in contact with each other on at least one of the at least one inclined side surface of the protrusion.
