Abstract: A display substrate and a display device including the display substrate are provided. The display substrate includes an alignment mark in an alignment region of the display substrate; and a blocking structure in a preset region around the alignment mark, wherein the blocking structure is arranged to block residual particles carried by a rubbing roller during rubbing.

Abstract: Embodiments of the present invention disclose a method for detecting a bright spot of a liquid crystal display panel, which belongs to the field of display. The method can solve a technical problem of miss detecting by the bright spot detection method in the prior art which o can not detect a bright spot caused by the short circuit between a data line and a pixel electrode. The method for detecting a bright spot of a liquid crystal display panel comprises: scanning gate lines of the liquid crystal display panel, and simultaneously outputting low level signals by data lines of the liquid crystal display panel; and, stopping the scanning of the gate lines of the liquid crystal display panel, and simultaneously outputting high level signals by the data lines. The method may be used for detecting liquid crystal display panels of ADS type.

Abstract: The embodiment of the present invention discloses a method for detecting the bright point in the liquid crystal display panel. The method comprises applying a cutoff voltage to a gate, remaining a thin film transistor TFT switch turning-off, applying a voltage higher than the voltage of a common electrode to a data line, and detecting a bright point under a black image based on the voltages applied to the gate and the data line. The present invention realizes the bright point detecting under a black image.
