Abstract: The present application provides a liquid crystal display panel and a display device. Invalid pixels of the liquid crystal display panel include a test pixel. In this structure, when no tests are required, the test pixel is in an off state, and there is no voltage difference between a pixel electrode and a common electrode to cause rotation of liquid crystals. When a test is required, the test pixel is in an on state, and the pixel electrode is disconnected from the common electrode to cause a voltage difference, so that the liquid crystals are normally rotated.

Abstract: The present invention provides a display panel and a chip. A frequency of a signal in a first frequency signal transmission line is greater than a frequency of a signal in a second frequency signal transmission line. A distance between a first signal input pad and a first signal output pad is smaller than a distance between a second signal input pad and a second signal output pad, and the distance between the second signal input pad and the second signal output pad is smaller than a distance between a third signal input pad and a third signal output pad. The invention can reduce the influence of the impedance of the signal transmission line on the signal.

Abstract: A display panel and a fabricating method thereof are provided. The display panel is provided with a bending region and a non-bending region. The display panel has a flexible substrate, a first line layer, an insulating layer, and a second line layer, which are layer-stacked. The first line layer has first lines. The insulating layer corresponding to each of the first lines is provided with at least two through holes penetrating the insulating layer. The through holes are defined at two ends of the bending region adjacent to the non-bending region. The second line layer has second lines. The second lines are aligned with the first lines in a one-to-one manner. The second lines extend and penetrate the through holes to electrically connect to the first lines. The fabricating method has steps: providing a flexible substrate, fabricating a first line layer, an insulating layer, a second line layer.
