Abstract
A display panel is provided. The display panel includes a plurality of pixel units arranged in a fingerprint recognition region. Each of the plurality of pixel units includes a first electrode and a light-emitting layer. A driving unit of each pixel unit includes a storage capacitor. An orthographic projection of the storage capacitor on a plane of the display panel is located within an orthographic projection of the corresponding first electrode on the plane of the display panel. An orthographic projection of the light-emitting layer of each organic light-emitting device on the plane of the display panel is located within an orthographic projection of the corresponding first electrode. A distance between an edge of an orthographic projection of the first electrode and an edge of an orthographic projection of the light-emitting layer of each red and/or green organic light-emitting device is larger that of each blue organic light-emitting device.
