ABSTRACT:
An IPS mode LCD for improving image quality and a manufacturing method thereof are provided. When a common-voltage supply line and common lines are formed on different layers using different materials and connected via a contact hole, a contact resistance is increased due to an increase of a contact area and thus common signals are delayed. To solve the common signal delay, the common-voltage supply line and the common lines are integrally formed using the same material so that common signals are applied to the common lines without delay. Thus, preventing image quality deterioration due to the delay of the common signals.
