Liquid crystal display device including common voltage compensating circuit

摘要

A liquid crystal display device may include: a liquid crystal display panel comprising a first and a second common voltage supply line formed in a first direction at both side ends of the substrate, and at least one feedback line formed in the first direction and connected to the first common voltage supply line and/or the second common voltage supply line; and at least one common voltage compensating circuit, an output terminal of which is connected to the first and the second common voltage supply lines, and an input terminal of which is connected to the feedback line.

1. A liquid crystal display device, comprising:
a liquid crystal display panel comprising a first and a second common voltage supply line formed in a first direction at both side ends of the substrate, and at least one feedback line formed in the first direction and connected to the first common voltage supply line and/or the second common voltage supply line; and a third common voltage supply line formed in the first direction an end of which is connected to the other one of the first and the second common voltage supply line, wherein at least one common voltage compensating circuit is disposed at a side end of the liquid crystal display panel, the output terminal of which is connected to the other end of the first and the second common voltage supply line, and the input terminal of which is connected to the other end of the feedback line, wherein the at least one common voltage compensating circuit comprises a first common voltage compensating circuit and a second common voltage compensating circuit, and wherein the first and the second common voltage compensating circuit are set to have different voltage gains to each other.
