Liquid crystal display panel for testing line on glass type signal lines

Abstract

A liquid crystal display panel for making a LOG-type signal line test for detecting a short imperfection with a LOG-type signal line group even upon shorting of a shorting bar. In the panel, a picture display part has a plurality of liquid crystal cells, each of which is arranged at each intersection area between gate lines and data lines. Line on glass type signal lines are provided at an outer area of the picture display part by a line on glass system to apply signals required for driving external drive integrated circuits. At least two gate-shorting bars apply a test signal by separating the gate lines into two groups and separating partial signal lines of the line on glass type signal lines into at least two groups. At least two data shorting bars apply a test signal by separating the data lines into two groups and separating the remaining signal lines of the line on glass type signal lines into at least two groups.
