Abstract

Aspects of the invention can provide a fast-response, homeotropic-mode, liquid crystal display device performing bright and high-quality display having a feature of wide-viewing angle. The liquid crystal display device includes a pair of substrates, each having electrodes on one surface thereof, a liquid crystal layer sandwiched between the pair of substrates, having the electrodes interposed therebetween, and a display area having a plurality of dot areas two-dimensionally arrayed therein. The liquid crystal layer can include liquid crystal vertically aligned in an initial state. In a single dot area, each pixel electrode has a plurality of island-shaped portions and connecting portions electrically connecting adjacent two of the island-shaped portions to each other, and the pluralities of island-shaped portions are arrayed in a stagger pattern in plan view.

Dependent claims

A liquid crystal display device, comprising:

a pair of substrates having a display area including dot areas;
an electrode in each of the dot areas, each of the electrodes including at least two island-shaped portions aligned in a first direction;
a connecting portion electrically connecting adjacent two island-shaped portions in each of the dot areas;
a liquid crystal layer sandwiched between the pair of substrates, including liquid crystal with homeotropic orientation;
and
the island-shaped portions being arrayed in the display area substantially in a honeycomb pattern in a plan view, the adjacent island-shaped portions being shifted out of alignment in the first direction in which the island-shaped portions of each dot area are aligned so that the center of an island-shaped portion in one dot area is aligned with the connecting portion of an adjacent dot area in a second direction that intersects the first direction.
