Claim:
1. A liquid crystal display device comprising: a first gate signal line and a second gate signal line extending in a first direction, a first drain signal line and a second drain signal line extending in a second direction intersecting with the first gate line and the second gate line, a first pixel and a second pixel surrounded by the first gate signal line, the second gate signal line, the first drain signal line, and the second drain signal line, a first thin-film transistor connected to the first drain signal line and placed close to the first gate signal line, a second thin-film transistor connected to the second drain signal line and placed close to the second gate signal line, wherein the first pixel has a first pixel electrode, and the second pixel has a second pixel electrode, wherein the first pixel electrode and the second pixel electrode are opposed to a common electrode through a first insulation film, wherein the first thin-film transistor has a first source electrode electrically connected to the first pixel electrode, and the second thin-film transistor has a second source electrode electrically connected to the second pixel electrode, wherein the first source electrode has a first portion extending in the first direction from the first thin film transistor toward the second drain signal line and a second portion extending in the second direction from an end of the first portion toward the second gate signal line, wherein the second source electrode has a third portion extending in the first direction from the second thin film transistor toward the first drain signal line and a fourth portion extending in the second direction from an end of the third portion toward the first gate signal line, wherein the first portion, the second portion, the third portion and the fourth portion are formed on a same layer as each of the first source electrode and the second source electrode, and formed on a different layer from each of the first pixel electrode and the second pixel electrode, and wherein at least one of the first portion and the second portion are forming a capacitive element with the common electrode, and at least one of the third portion and the fourth portion are forming a capacitive element with the common electrode.
