Abstract: Embodiments of the invention provide a self-capacitance touch liquid crystal grating, a manufacturing method thereof, a driving method thereof, a self-capacitance touch liquid crystal 3D display panel, and a self-capacitance touch liquid crystal 3D display device. In the grating provided by embodiments of the present invention, as orthographic projections of strip-shaped electrodes on a sensing electrode layer are respectively located in row spacing areas or column spacing areas formed through sensing electrodes arranged in a matrix form, the sensing electrode-to-earth capacitance is located between a surface-shaped electrode and the sensing electrodes, and the strip-shaped electrode will not cause the sensing electrode-to-earth capacitance to be increased. Therefore, RC loading of the sensing electrodes can be largely reduced, and also the interference between the sensing electrodes and the grating can be avoided, so that touch operations will not interfere with operations of the grating.
