Abstract: The present disclosure provides a shift register unit, a gate driver circuit, and a display device, belonging to the field of display technology, which can solve the problem of unstable threshold voltage and current leakage of thin film transistors in existing shift register units. The shift register unit in the present disclosure includes: an input subcircuit, an output subcircuit, a pull-down control subcircuit, a pull-down subcircuit, a first noise reduction subcircuit, a first auxiliary control subcircuit, and a second auxiliary control subcircuit. The first auxiliary control subcircuit is configured to write the third reference level signal to the pull-down control node when the pull-down node is the first reference level signal, and control the pull-down subcircuit to be closed to control the first noise reduction subcircuit to be open.

Abstract: A semi-transparent semi-retroreflective film and an air display device are provided. The air display device includes: a first polarizer and a second polarizer assembled with each other to form a cell; a semi-transparent semi-reflective structure and a semi-transparent semi-retroreflective film disposed between the first polarizer and the second polarizer; a first ¼ wave plate disposed at a side of the air display device adjacent to the first polarizer; and a second ¼ wave plate disposed between the semi-transparent semi-reflective structure and the semi-transparent semi-retroreflective film. The air display device is configured such that polarized light incident from the first polarizer, after being processed by an internal optical path of the air display device, exits from the second polarizer to form an air image at a side of the air display device away from the first polarizer.
