Claim Text:
1. A display panel, comprising an active area and a vacant area surrounding the active area, and a dummy pattern area without display functionality being along boundary between the active area and the vacant area; the active area, the vacant area and the dummy pattern area are disposed on pattern layers of the display panel for lithography or etching in a wet process, and the pattern layers comprise: a pixel electrode layer, a first metal layer and a second metal layer; the active area and the dummy pattern area are disposed on the pixel electrode layer and the dummy pattern area comprises a plurality of dummy pixels; the active area comprises a plurality of pixels having normal pattern design, and pattern design of the dummy pixels is identical to the normal pattern design of the pixels, and pattern of the dummy pixels near the vacant area is an irregular pattern; wherein the irregular pattern is generated from solution concentrations being existing at an intersection area of the dummy pattern area and the active area, at the active area, and at the dummy pattern area, and the solution concentration at the dummy patter area gradually decreases from the intersection area towards the vacant area during the wet process.
