The present disclosure discloses a display panel, a display device and a manufacturing method of a display panel. The display panel includes: a substrate; a pixel definition layer disposed on the substrate, with a plurality of pixel regions being defined in the pixel definition layer; and an organic common layer disposed on the pixel regions and the pixel definition layer; wherein, a thickness of at least one portion of the organic common layer corresponding to the pixel definition layer is less than that of at least one portion of the organic common layer corresponding to the pixel region; or at least one recess is disposed in a portion of the pixel definition layer between adjacent pixel regions or in every pixel definition layer between two adjacent pixel regions, and the organic common layer covers the recess.

Display panel, display device and manufacturing method of display panel

A pixel compensating circuit includes a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a driving transistor, a first capacitor, and an organic light emitting diode element. The first transistor controls transmission of a data signal to a first electrode plate of the first capacitor. The second transistor controls transmission of a reference voltage signal to the first electrode plate of the first capacitor. The driving transistor determines an amount of a driving current. The third transistor controls connection and disconnection between the gate electrode and a drain electrode of the driving transistor. The fourth transistor transmits the driving current from the driving transistor to the organic light emitting diode element. The fifth transistor controls transmission of a supply voltage to the source electrode of the driving transistor; and the organic light emitting diode element emits light in response to the driving current.

Pixel compensating circuit and method of organic light emitting display

An inverter includes first, second, third, fourth, and fifth transistors, and first and second capacitors. The transistors and capacitors are connected in such way that the reverse conduction of the second transistor is prevented through controlling the gate electrode of the second transistor and maintaining the electrical potential at the gate electrode of the fifth transistor by the second capacitor. The electrical potential at the gate electrode of the fifth transistor is maintained stable when a first clock signal changes from high to low (when the first to fifth transistors are NMOS transistors) or from low to high (when the first to fifth transistors are PMOS transistors), so that the output signal of the inverter may not be affected by a change of the first clock signal, thus enabling the inverter to generate a stable output signal and a display panel comprising the inverter to obtain a better display effect.
