Benefits of technology

[0008]The present invention provides a display panel in which damage from test lines that are corroded by heat or moisture is effectively prevented from being transmitted to the display panel.

Problems solved by technology

However, the separated test lines are exposed outside the liquid crystal display, and the separated test lines are thereby often damaged, such as from corrosion due to heat or moisture from outside the liquid crystal display, for example.
Moreover, this damage can be transmitted to the signal lines of the liquid crystal display.

Abstract

A display panel includes an insulation substrate having a display area and a peripheral area, wires disposed on the insulation substrate in the display area, first and second testing lines disposed on the insulation substrate and aligned substantially parallel to each other, and a diode unit disposed between the wires and one of the first testing line and the second testing line. The wires extend from the display area into the peripheral area and through diodes included in the diode unit, and the wires are electrically connected to the one of the first testing line and the second testing line.

Description

[0001]This application claims priority to Korean Patent Application No. 10-2009-0102475, filed on Oct. 27, 2009, and all the benefits accruing therefrom under 35 U.S.C. §119, the content of which in its entirety is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002](1) Field of the Invention[0003]The present invention relates to a display panel and, more particularly, the present invention relates to a display panel that executes an array test.[0004](2) Description of the Related Art[0005]Liquid crystal displays (“LCDs”) are a type of flat panel display that is frequently used as a display device. A liquid crystal display typically includes two display panels on which field generating electrodes, such as pixel electrodes and a common electrode, are disposed, and a liquid crystal layer interposed between the two display panels. The liquid crystal display applies voltages to the field generating electrodes to generate an electric field in the liquid crystal layer. As a ...
