Liquid crystal display device

摘要

A first substrate includes a gate line extending in a first direction and a source line extending in a second direction. A first sub-common electrode is formed on the gate line. A first main-common electrode is formed along the source line so as to be connected with the first sub-common electrode. A second main-common electrode is formed extending in the second direction and facing the source line. The second main-common electrode is set to the same potential as the first main-common electrode. A second substrate includes a third main-common electrode extending in the second direction so as to face the second main-common electrode. The third main-common electrode is set to the same potential as the second main-common electrode. A second sub-common electrode is connected with the third main common electrode. The second sub-common electrode is formed so as to face the first sub-common electrode on the gate line.
