    • A display device is provided to connect test pads capable of supplying a test signal to signal lines to test the operation of an element in a display area and couple the signal lines to the test pads through bridge lines formed of a corrosion-resistant material to protect the signal lines from corrosion. A display device includes a display panel, a plurality of signal lines(210,220), and test pad parts(310,320,330,340,350). The display panel includes a display area(D) and a peripheral area(P). The plurality of signal lines are formed in the peripheral area and provide signals for displaying images to the display panel. The test pad parts are formed in the peripheral area of the display panel and connected to at least part of the plurality of signal lines. The test pad parts respectively include test pads, lines respectively extended from the test pads, and bridge lines respectively connecting the extended lines to the signal lines. The bridge lines are formed of a corrosion-resistant material.
    • 提供了一种显示装置,用于连接能够将测试信号提供给信号线的测试点,以测试显示区域中的元件的操作,并通过由耐腐蚀材料形成的桥接线将信号线耦合到测试焊盘,以保护 信号线从腐蚀。 显示装置包括显示面板,多条信号线(210,220)和测试垫部分(310,320,330,340,350)。 显示面板包括显示区域(D)和外围区域(P)。 多个信号线形成在周边区域中,并提供用于向显示面板显示图像的信号。 测试焊盘部分形成在显示面板的周边区域中,并连接到多条信号线的至少一部分。 测试焊盘部分分别包括测试焊盘,分别从测试焊盘延伸的线以及分别将扩展线连接到信号线的桥接线。 桥线由耐腐蚀材料形成。
