The shift register includes a first stage having first and second transistors and a second stage having a third and fourth transistor. A voltage of a control electrode of the first transistor is boosted by a voltage of a first pulse line changing from low to high. In an On state, the second transistor connects the control electrode of the first transistor and a constant voltage line. A voltage of a control electrode of the third transistor is boosted by a voltage of a second pulse line changing from low to high. In an On state, the fourth transistor connects the control electrode of the third transistor and a constant voltage line. The fourth transistor is switched on by a signal from the first stage.Type: GrantFiled: November 2, 2015Date of Patent: October 4, 2016Assignees: Japan Display Inc., PANASONIC LIQUID CRYSTAL DISPLAY CO., LTD.Inventors: Toshio Miyazawa, Iwao Takemoto, Atsushi Hasegawa, Masahiro Maki, Kazutaka Goto
