Abstract

A display device is provided and includes pixel electrodes, each of the pixel electrodes including a plurality of electrode sections which are arranged parallel to each other. Each electrode section is bent approximately in the middle along its extension direction in plan view. The pixel electrodes include a center connection portion adapted to connect together the electrode sections at their bent portions, and include end connection portions adapted to connect together the electrode sections at their end portions, and include protruding portions each of which is formed by extending the end connection portion in such a manner as to protrude from the arranged electrode sections. The display device also includes a substrate on which the pixel electrodes are arranged, an opposed substrate provided to face the side of the substrate on which the pixel electrodes are formed, and a liquid crystal layer filled and sealed between the substrate and opposed substrate.

Claims (21)

1. A display device comprising:

pixel electrodes, each of the pixel electrodes including

a plurality of electrode sections which are arranged parallel to each other, each electrode section being bent approximately in the middle along its extension direction in plan view,

a center connection portion adapted to connect the electrode sections together at their bent portions,

end connection portions adapted to connect together the electrode sections at their end portions, and

protruding portions each of which is formed by extending the end connection portion in such a manner as to protrude from the arranged electrode sections;

a substrate on which the pixel electrodes are arranged;

an opposed substrate provided to face the side of the substrate on which the pixel electrodes are formed; and

a liquid crystal layer filled and sealed between the substrate and opposed substrate,

wherein the protruding portions are extended only on the inner angle side in the bending direction of the electrode sections comprising the pixel electrodes.

2. A display device comprising:

pixel electrodes, each of the pixel electrodes including

a plurality of electrode sections which are arranged parallel to each other, each electrode section being bent approximately in the middle along its extension direction in plan view,

a center connection portion adapted to connect the electrode sections together at their bent portions,

end connection portions adapted to connect together the electrode sections at their end portions, and

protruding portions each of which is formed by extending the end connection portion in such a manner as to protrude from the arranged electrode sections;

a substrate on which the pixel electrodes are arranged;

an opposed substrate provided to face the side of the substrate on which the pixel electrodes are formed; and

a liquid crystal layer filled and sealed between the substrate and opposed substrate,

wherein each of space portions enclosed by the electrode sections, center connection portion and end connection portion has a shape in plan view all of whose inner angles are obtuse angles.

3. The display device of claim 2 , wherein each of the space portions is hexagonal in plan view.
