According to one embodiment, a liquid crystal display device includes an insulation film disposed over a gate line, a storage capacitance line, a source line, and first main common electrodes disposed on the insulation film. The first main common electrodes include a discontinuous part in at least one of a first intersection part at an intersection between the storage capacitance line and the first source line and a second intersection part at an intersection between the storage capacitance line and the second source line. The liquid crystal display device also includes a main pixel electrode and a sub-pixel electrode which are disposed on the insulation film.
