Abstract:
A liquid crystal display device includes a pair of substrates; a liquid crystal sealed between the substrates; plural pixel regions each having a first pixel electrode formed on one of the pair of substrates and a second pixel electrode separated from the first pixel electrode; a TFT having a source electrode which is electrically connected to the first pixel electrode; a control capacitance portion which has a control capacitance electrode electrically connected to the source electrode and opposed to at least part of the second pixel electrode via an insulating film, and which thereby establishes capacitive coupling between the source electrode and the second pixel electrode; linear projections formed on the other substrate; and apertures formed in the first and second pixel electrodes so as to occupy parts of overlap regions of the linear projections and the first and second pixel electrodes as viewed perpendicularly to the substrate surfaces, for controlling the positions of singular points of alignment vectors of the liquid crystal.
