A light emitting display panel includes a driving transistor, and a storage capacitor including at least three electrodes to reduce a size of the driving transistor or the storage capacitor. The light emitting display panel comprises a light emitting element, the driving transistor connected to the light emitting element, and the storage capacitor connected to a gate and a first electrode of the driving transistor. The driving transistor includes a light shielding electrode used as the gate of the driving transistor, a buffer covering the light shielding electrode, an active portion provided on an upper surface of the buffer, forming the first electrode, a second electrode and a semiconductor portion of the driving transistor, a gate insulating layer covering the active portion, and a gate electrode provided on an upper surface of the gate insulating layer and connected to the light shielding electrode.
