Abstract
A display panel, a manufacturing method thereof, and a display device are provided. Through a configuration of a capacitor in the display panel, where the capacitor is connected to a first thin film transistor, a photosensitive pattern in the capacitor senses light, such that when the light varies, a varying charge quantity of the photosensitive pattern in the capacitor varies current of the first thin film transistor, increasing a sensitometric characteristic of the first thin film transistor, and increasing fingerprint recognition effect, and a second gate is configured to be a capacitor polar plate, decreasing a thickness of an array substrate.
