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.
