The disclosure discloses an organic electroluminescent display panel and a display panel, where initialization transistor and the control transistor are connected by a second power source signal line, and if the initialization transistor is turned on by first scan signal line, and if the control transistor is turned on by light emitting control line, then different electrical signal will be loaded on the second power source signal line to thereby reset the gate of a drive transistor in an initialization stage, and to load power source voltage to the source of the drive transistor for light emission and displaying, in a light emitting stage.
