Abstract: A display panel includes a plurality of touch blocks matrix-arranged and corresponding to each of two or more adjacent pixel areas of the plurality of pixel areas, and first, second, third and fourth test signal lines through which first, second, third and fourth test signals are supplied by an auto probing unit. Accordingly, not only a defect in an image output function, but also a defect in a touch sensing function can be inspected prior to a modularization process by using the first, second, third and fourth test signals.

Abstract: A display panel having a touch sensor includes a pixel array, touch sensor blocks, a touch inspection pad unit, and an image inspection pad unit. In the pixel array, a plurality of pixels is disposed in a matrix form. The touch sensor blocks are connected to respective pluralities of the pixels in the pixel array. The touch inspection pad unit divides the touch sensor blocks into odd-numbered touch sensor blocks and even-numbered touch sensor blocks and a first touch inspection pad is coupled to the odd-numbered touch sensor blocks, while a second touch inspection pad is coupled to the odd-numbered touch sensor blocks. The image inspection pad part is commonly coupled to the odd-numbered touch sensor blocks and the even-numbered touch sensor blocks.
