Abstract

See full text

The present disclosure provides a mask plate, a display panel and a display device. The mask plate comprises: a transparent substrate; an opaque film layer, the opaque film layer being disposed on the transparent substrate. The opaque film layer includes a plurality of first regions and a plurality of second regions, a first sub-region in the first region and the second region are transmissive, and the remaining portion in the first region is semi-transmissive. The mask plate is used to form via holes in the planarization layer of the display panel by exposure, so that the angles between the metal electrode layers disposed in the via holes and the source/drain layers of the display panel are small and diversified, decreasing the visibility of the metal electrode layers.
