摘要： A liquid crystal display device includes a pixel electrode, a common electrode, and an insulating layer which is formed between the pixel electrode and the common electrode. The pixel electrode or the common electrode includes at least one strip shaped portion which is extended in a first direction. A first thickness of the insulating layer between the pixel and common electrodes at a first portion extending from a vicinity of end of the at least one strip shaped portion in the first direction toward the end of the at least one strip shaped portion is thicker than a second thickness of the insulating layer between the pixel and the common electrodes at a second portion extending from the vicinity of end of the at least one strip shaped portion in the first direction toward a center of the at least one strip shaped portion.

摘要： 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.

Aperture regions surrounded by the drain lines and the gate lines include an aperture region including the slits having a first inclined angle and an aperture region including the slits having a second inclined angle, the second inclined angle being different from the first inclined angle. The aperture region including the slits having the first inclined angle and the aperture region including the slits having the second inclined angle are alternately formed in the first direction. Within the aperture regions arranged adjacent to each other in the first direction, a first region and a second region forming a pair by being arranged so as to be opposed to each other via one of the gate lines form one of pixels.
