Abstract
A liquid crystal display device includes a TFT substrate with gate lines and drain lines, and pixel electrodes each formed in a region surrounded by the gate lines and drain lines. Protrusions are formed below the gate lines, each of the protrusions having an upper surface and at least one inclined side surface. A gate insulating film is formed over the gate lines, a semiconductor layer formed on the gate insulating film, and drain electrodes formed and source electrodes formed over the semiconductor layer. Channel portions are 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 protrusions, the pixel and source electrode being in contact with each other on at least one inclined side surface of the protrusion.
