Abstract
A liquid crystal display device has data signal lines consisting of recurrently formed first, second, and third lines that have open ends and are used for data entry, first diodes formed on the first lines, and second diodes formed on the second lines and having an opposite polarity to the first diodes. In this liquid crystal display device, a test for uneven display of colors is conducted by putting a short-circuiting bar for supplying testing voltages to the data signal lines in contact with the data signal lines.
