Patent ID: 7952672

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate; and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein the first substrate includes a plurality of scanning signal lines; a plurality of video signal lines which intersects the plurality of scanning signal lines, a first insulation film which is formed above the video signal lines, a counter electrode which is formed above the first insulation film, a second insulation film which is formed above the counter electrode, and a pixel electrode which is formed above the second insulation film and to which a video signal is supplied from the video signal line via a switching element, the liquid crystal layer is configured to be driven by an electric field generated due to difference in potential between the pixel electrode and the counter electrode, the video signal line is covered with the counter electrode by way of the first insulation film, and one pixel region sandwiched between two video signal lines arranged adjacent to each other is divided into a first pixel region, a second pixel region and a third pixel region in order from one video signal line to another video signal line, wherein in the first pixel region and the third pixel region, the pixel electrode has a linear pixel electrode and has a line width of 4.0 μm or less and overlaps with the counter electrode by way of the second insulation film, and the counter electrode is provided in a projecting manner on both sides of the linear pixel electrode as viewed in a plan view, and in the second pixel region, the pixel electrode has a linear pixel electrode and has a line width of 2.5 μm or less and does not overlap with the counter electrode, and the pixel electrode and the counter electrode are alternately arranged to in a spaced-apart manner from each other in a plan view.
