The present disclosure provides a pixel circuit, a driving method and a display device. The pixel circuit includes a light-emitting element, a driving circuitry, a first resetting circuitry, a first control circuitry and a second control circuitry. The first resetting circuitry writes a first initial voltage into a first node under the control of a first scanning signal. The first control circuitry controls a power supply voltage end to be electrically coupled to a second node under the control of a second light-emission control signal. The second control circuitry controls a third node to be electrically coupled a first electrode of the light-emitting element under the control of a first light-emission control signal. The driving circuitry controls the second node to be electrically coupled to the third node under the control of a potential at the first node.
