Abstract:
The display device includes first and second gate driver circuits. Each gate driver circuit including a shift register and a plurality of amplifier circuits connected to one end of a gate line. The first and second gate driver circuits respectively have only a first and a second non-complementary switch provided in a last stage of their amplifier circuits, where at least one of the first and second switches is an NMOS switch or a PMOS switch. As a result, a display device is provided, which has driver circuits arranged in a well-balanced manner to achieve a left-right symmetrical display area.
