Potential shift circuit and display device having same

The invention discloses a potential shifting circuit and a display device. The potential shifting circuit comprises a differential input circuit, a current limiting circuit, a latch circuit and a voltage shielding circuit. The voltage shielding circuit includes first to fourth shielding transistors. The first shielding transistor and the second shielding transistor are connected in series betweenthe differential input circuit and the second output end, and the third shielding transistor and the fourth shielding transistor are connected in series between the differential input circuit and thefirst output end. Grids of the first shielding transistor and the third shielding transistor receive a first voltage, and grids of the second shielding transistor and the fourth shielding transistor receive a second voltage smaller than the first voltage. Substrates of the first shielding transistor and the third shielding transistor receive a third voltage, and substrates of the second shieldingtransistor and the fourth s
