Patent ID: 7990503

Claim:
A liquid crystal display device comprising: a pair of substrates opposed to each other; a liquid crystal sealed between the pair of substrates; plural gate bus lines formed on one of the pair of substrates; plural drain bus lines formed so as to cross the gate bus lines with an insulating film interposed in between; plural pixel regions each having a first pixel electrode formed on the one substrate and a second pixel electrode formed on the one substrate and separated from the first pixel electrode; a transistor disposed for each of the pixel regions and 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 alignment restriction structures formed on the other substrate, for restricting alignment of the liquid crystal; and singular point control apertures formed in the first and/or second pixel electrode so as to occupy parts of overlap regions of the alignment restriction structures and the first and/or second pixel electrode as viewed perpendicularly to surfaces of the substrates, for controlling positions of singular points of alignment vectors of the liquid crystal.
