The invention provides a display panel. The display panel comprises a substrate, a semiconductor active layer, a gate insulating layer and a gate positioned on the substrate successively, and a fluorescent layer. The fluorescent layer is positioned on the substrate, and used to shield light irradiated on the semiconductor when the substrate is peeled by a laser peeling technology subsequently. Theinvention also discloses a manufacturing method of the display panel and a display device. A metal shielding layer is replaced by the fluorescent layer, the fluorescent layer can absorbs high-energylight and then generates electron transition, and the electrons are transited from an original ground state electron track to a higher excitation state track. The excitation state track is instable, and when the higher excitation state track is transited back to the ground state of lower energy, low-energy light does not influence the semiconductor active layer. The fluorescent layer can absorb the high energy light but not reflect the high energy light. Thus, a better shielding effect can be realized, and the semiconductor active layer is avoided from deterioration.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Due to the characteristics of organic light-emitting diodes such as self-illumination, wide viewing angle, low energy consumption, and high contrast ratio, organic light-emitting diodes are known as the next-generation products of liquid crystal displays. Compared with the current low-temperature polysilicon technology, oxidation technology has obvious advantages in the direction of large-scale organic light-emitting diodes, with simple process and good uniformity. Among them, the top gate structure prevents the channel from being affected by the light from the display. However, flexible bending is an important direction for the development of organic light-emitting diodes. When the flexible thin film substrate is laser-stripped from the glass surface, the channel will be irradia...
