Abstract: A display panel includes a plurality of display elements over a substrate, each including at least one first light-emitting element for emitting a first light out of a first light-emitting surface and at least one second light-emitting element for emitting a second light out of a second light-emitting surface opposing to the first light-emitting surface. Each first light-emitting element has a first light-emitting layer between two first electrodes, which are respectively transparent and reflective so that the first light can transmit out of the first light-emitting surface. Each second light-emitting element includes a second light-emitting layer between two second electrodes, which are respectively transparent and reflective so that the second light transmits out of the second light-emitting surface. The first and second light-emitting surface are below and over the substrate respectively. A driving circuit is configured to drive the display panel.

Abstract: The present disclosure provides a transistor and a manufacturing method thereof, a display substrate and a display device. The transistor includes: a base structure; an active layer on the base structure; and a gate electrode, a source electrode and a drain electrode that are all located on a side of the active layer distal to the base structure. The active layer includes a first region corresponding to an orthographic projection of the gate electrode on the base structure and a second region outside the orthographic projection. A surface of the base structure in contact with the active layer in the first region is not in the same plane as a surface of the base structure in contact with the active layer in the second region. The active layer in the first region has substantially the same thickness as a thickness of the active layer in the second region.
