摘要： Provided are a liquid crystal display device with horizontal electric field mode, in which a decrease in driving speed can be suppressed by reducing the resistance of a wiring even when the number of pixels is increased, and a manufacturing method thereof. One of a scan wiring and a signal wiring is divided in an intersection portion where the scan wiring and the signal wiring intersect with each other, and the separated wirings are connected with a connection electrode positioned over a thick insulating film. Accordingly, parasitic capacitance at the intersection portion can be reduced, preventing the decrease in the driving speed. The connection electrode is formed at the same time as formation of a pixel electrode and a common electrode using a low-resistance metal, which contributes to the reduction in manufacturing process of the liquid crystal display device.
