Abstract
The present invention provides a liquid crystal grating substrate, a liquid crystal grating and a stereoscopic display device The liquid crystal grating substrate, the liquid crystal grating and the stereoscopic display device provided in the present invention can control the voltages of the electrode strips respectively, thereby not only improving the control precision of the liquid crystal grating, but also ensuring diversified control forms to meet various adjustment requirements for the width of the light transmissive area or non-light transmissive area of the liquid crystal grating; meanwhile, the liquid crystal grating is easy to drive and the sizes of the light transmissive areas can be controlled, thus the circuit design difficulty and the production cost are reduced, and the 3D crosstalk problem can be solved.
