Abstract

A liquid crystal display panel with reduced flicker comprises an active matrix substrate equipped with a plurality of thin film transistors. The active matrix substrate has an active area that is formed with a plurality of first signal lines and a plurality of second signal lines crossing each other. The active area includes a plurality of pixels arranged in a matrix. There are outer-lead bonding areas around the active area. There are a plurality of pad areas within the outer-lead bonding areas. A plurality of second wires arranged in a fan-out configuration extend from the pad areas and stretch toward the active area. The second wires are connected to their respective first signal lines by their serpentine or zigzag routes resulting in various wire lengths. A frame-like lead overlaps the second wires, and a capacitor exists between each of the second wires and the closed frame-like lead. The induced capacitor and the resistance of the corresponding second wire together result in a compensation effect so as to uniform the time constants of the plurality of first signal lines.
