LCD panel having a plurality of shunt buses

摘要

An active matrix type LCD panel includes an active matrix portion including a plurality of this film transistors, a plurality of scan signal lines and a plurality of data lines, and a shunt bus formation portion including at least first and second bus lines formed independently of each other. The first shunt bus line is connected to the scan signal lines 1 and the second shunt bus line is connected to the data lines to thereby protect the transistors against a surge voltage such as electrostatic charges and facilitate a test for short-circuit conditions between the adjacent lines.
