Abstract: A substrate and a display device are provided. A first film layer of the substrate is formed on a third film layer and patterned to form a target pattern. A second film layer is formed on the third film layer and the first film layer. Within a distribution area of the target pattern, film edges of the first film layer are formed with protrusion structures facing the second film layer. Based on the protrusion structures, a deformable margin of the first film layer and the second film layer at a stacking position is increased, and a pattern of the second film layer is thus prevented from being cracked to generate cracks.

Abstract: An organic light-emitting diode display panel includes a thin-film transistor substrate, a plurality of thin-film transistors, and a plurality of organic light-emitting diodes. The thin-film transistors are disposed on a side of the thin-film transistor substrate. The organic light-emitting diodes are disposed on a side of the thin-film transistor substrate away from the thin-film transistors. The organic light-emitting diodes are disposed on a flat surface and will not be affected by surface fluctuations caused by the thin-film transistors. A space usage of the organic light-emitting diodes can be maximized, thereby increasing a pixel density of the organic light-emitting diode display panel.
