    摘要： A display panel includes a plurality of display elements over a substrate, each comprising 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 for driving is configured to drive the display panel.
