Abstract: In one embodiment, a first substrate is provided with first and second main pixel electrodes electrically connected each other extending along a first direction, respectively. A second substrate includes first to third main common electrodes electrically connected each other extending along the first direction, respectively. The first main pixel electrode is arranged between the first and second main common electrodes, and the second main pixel electrode is arranged between the second and third main common electrodes. Four inter-electrode distances are formed. One of the four inter-electrode distances is set to an optimal inter-electrode distance, and one of the four inter-electrode distances is different from at least one of the other three inter-electrode distances. Herein, the optimal inter-electrode distance is defined as follows: in a range of voltage which is applied between the electrodes, more than 90% of a peak transmissivity is obtained by the optimal inter-electrode distance.

Abstract: A liquid crystal display device includes a first substrate and a second substrate. The first substrate includes a pixel electrode having a contact portion and a main pixel electrode extending in a second direction from the contact portion so as to form one end opposite to the contact portion. The second substrate includes a pair of main common electrodes arranged on both sides sandwiching the main pixel electrode and extending in the second direction. The width of the contact portion in a first direction orthogonally crossing the second direction is larger than the width of the main pixel electrode in the first direction. The main common electrode includes a convex portion provided in a position more apart from the contact portion than the one end of the main pixel electrode and protruding in the first direction.

Abstract: A liquid crystal display device includes a first substrate, a second substrate and a liquid crystal layer held therebetween. In the first substrate, first and second semiconductor layers are arranged apart from each other. A gate line is arranged on an insulating film extending in a first direction so as to cross the first semiconductor layer. A source line extends in a second direction and contacts the first semiconductor layer. A connection portion is arranged extending in the second direction for electrically coupling the first semiconductor layer and the second semiconductor layer. A main common electrode is arranged extending in the second direction so as to face the source line. A pixel electrode passes a region facing the connection portion and extending in the second direction so as to be apart from the main common electrode. The pixel electrode is electrically coupled to the connection portion.
