A pixel electrode having a first belt-like main electrode is arranged approximately in a central portion between the first source line and the second source line and extending in the second direction. A first belt-like sub-electrode covers the gate line between the first source line and the second source line and extending in the first direction. The second substrate includes a counter electrode having a second main electrode arranged on the first and second source lines and extending in the second direction. A liquid crystal layer is held between the first substrate and the second substrate.
