The invention discloses a display panel and a
display device. A threshold compensation circuit comprises a first threshold compensation
transistor, a second threshold compensation
transistor and a shielding
capacitor. Wherein a first threshold compensation
transistor and a second threshold compensation transistor are arranged; the length L of the channel region of the transistor can be increased equivalently, and the current I of the transistor is inversely proportional to the length L of the channel region, so that when the length L of the channel region is increased, the current I of the transistor can be reduced, and the quantity of charges flowing into the node N1 from the node N4 can be reduced. Moreover, by arranging the shielding
capacitor, the charge of the node N4 can be stored inthe shielding
capacitor by utilizing the charge
storage effect of the shielding capacitor. Therefore, during
signal switching on the scanning
signal line, charges of the node N4 can be prevented frombeing injected into the node N1, so that the
voltage of the grid
electrode of the driving transistor can be kept stable, and the display uniformity of the display panel is improved.
