    Abstract: A light-emitting substrate and a display device are provided. Each light-emitting unit includes a first voltage terminal. The first voltage line includes a first portion, a first connecting portion, and a second portion. The first portion is electrically connected with first voltage terminals of a first row to a Y-th row of light-emitting units in a corresponding column. An extension direction of a second portion of the first voltage line has an included angle with both the first direction and the second direction. The first connecting portion is at boundary of the Y-th row and a (Y+1)-th row of light-emitting units. The first transmission line is electrically connected with first voltage terminals of the (Y+1)-th row to an N-th row of light-emitting units in a corresponding column, and is electrically connected with the first connecting portion of the first voltage line corresponding to light-emitting units of a corresponding column.

    Abstract: The present disclosure provides a liquid crystal grating, a method for driving the liquid crystal grating, and a display device. In the embodiments of the present disclosure, by applying the second voltage and the third voltage that are mutually inverted with respect to the common electrode voltage, the situation in which a single phase voltage is applied to all grating electrodes corresponding to the power-on optical state can be avoided. Due to the capacitance of liquid crystal, the influence of the second voltage on the common electrode voltage and the influence of the third voltage on the common electrode voltage cancel each other out. Therefore, the fluctuation of the common electrode voltage caused by the capacitance of liquid crystal can be effectively reduced or eliminated, thereby avoiding the failure of the liquid crystal grating.
