Abstract

The disclosure provides a display panel and display device, relating to the field of display technology, and optimizes the design of pixel circuit. The display panel includes pixel circuit including driving transistor, first light-emitting control transistor, second light-emitting control transistor, and first transistor. Driving transistor is N-type transistor. Gate of first light-emitting control transistor and gate of second light-emitting control transistor are electrically connected to same light-emitting control line. First electrode of first light-emitting control transistor is electrically connected to first power line, and second electrode of first light-emitting control transistor is electrically connected to first electrode of driving transistor. First electrode of second light-emitting control transistor is electrically connected to second electrode of driving transistor, and second electrode of second light-emitting control transistor is electrically connected to light-emitting element. Gate of first transistor is electrically connected to first scanning line, first electrode of first transistor is electrically connected to first power line, and second electrode of first transistor is electrically connected to driving transistor.
