US Patent 7847872 Liquid crystal display and test method thereof

A liquid crystal display includes a plurality of pixel electrodes arranged in a matrix and having first and second sub-pixel electrodes differentiated in size from each other. First and second switching elements are connected to the first and second sub-pixel electrodes, respectively. First and second gate lines are connected to the first and second switching elements, respectively. A data line is connected to the first and second switching elements to transmit a data voltage. First and second gate shorting bars are connected to the first and second gate lines, respectively. The gate lines connected to the respective sub-pixels are connected to two or four gate shorting bars to allow an array test and a visual inspection test, and to thereby detect a bridge between respective sub-pixel electrode neighbors in a simplified manner.
