Abstract: The present disclosure provides a touch electrode structure, a touch panel and a display device, which relate to the field of touch control technologies. First touch electrodes and second touch electrodes of touch electrode patterns of the touch electrode structure are insulated. Branch electrodes of the first touch electrode and branch electrodes of the second touch electrode are disposed in at least one of a first region defined by first main body electrodes of two first touch electrodes and a second region defined by second main body electrodes of two second touch electrodes, such that a mutual capacitance of the at least one region is greater. When a user's finger approaches the at least one region, an induction amount of the touch electrode pattern changes greatly, such that the detection circuit accurately determines a touch position of the user's finger based on the greater change in the induction amount, and the touch performance of the touch panel is improved.

Abstract: 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.
