Abstract

A sealant contains a plurality of conductive members, and is formed in a closed pattern, when viewed from a direction normal to a surface of a first substrate or a second substrate. A second electrode is formed on a surface located on the first substrate side of the second substrate, and a first electrode, which is provided so as to face a part of the second electrode, and is electrically connected to the second electrode through the conductive members contained in the sealant, is formed over the first substrate. The first electrode is provided so as to at least partially overlap a crossing portion of the sealant.

Claims (17)

1. A liquid crystal display device, comprising:

a first substrate;

a second substrate provided so as to face the first substrate; and

a liquid crystal layer enclosed between the first substrate and the second substrate and surrounded by a sealant, wherein

the sealant contains a plurality of conductive members, and has a crossing portion formed so that a part of the sealant crosses another part thereof, when viewed from a direction normal to a surface of the first substrate or the second substrate,

a second electrode is formed on a surface located on the first substrate side of the second substrate,

a plurality of first electrodes, which are provided so as to face a part of the second electrode, and are electrically connected to the second electrode through the conductive members contained in the sealant, are formed over the first substrate, and

the first electrodes comprise a main electrode and at least one sub-electrode having a smaller area than an area of the main electrode, wherein the main electrode is provided so as to at least partially overlap the crossing portion of the sealant proximate a first corner of the second substrate and the sub-electrode having the smaller area is located proximate a second corner of the second substrate.

2. A liquid crystal display device, comprising:

a first substrate;

a second substrate provided so as to face the first substrate; and

a liquid crystal layer enclosed between the first substrate and the second substrate and surrounded by a sealant, wherein

a second electrode is formed on a surface located on the first substrate side of the second substrate,

a plurality of first electrodes, which are provided so as to face a part of the second electrode, and are electrically connected to the second electrode through a conductive member, are formed over the first substrate,

the first electrodes comprise a main electrode, and a sub-electrode having a different shape from that of the main electrode, when viewed from a direction normal to a surface of the first substrate,

the sub-electrode is shaped so as to extend along the sealant, when viewed from the direction normal to the surface of the first substrate; and

wherein the sub-electrode is formed in an L shape wherein the main electrode is provided to at least partially overlap the crossing portion of the sealant proximate a first corner of the second substrate and the sub-electrode having the different shape is located proximate a second corner of the second substrate.
