Abstract: Provided is a liquid crystal display panel, including an array substrate and a color filter substrate that are arranged oppositely, and a plurality of photo spacers disposed between the array substrate and the color filter substrate. The array substrate is provided with a plurality of via holes, wherein the plurality of via holes are arranged in an array along two directions. In at least one of the two directions, widths of target end faces of at least part of the plurality of photo spacers are greater than widths of first opening faces of the via holes, wherein the target end face of the photo spacer is an end face, proximal to the array substrate, of the photo spacer, and the first opening face of the via hole is an opening face, proximal to the color filter substrate, of the via hole.

Abstract: A safety footboard for a rail transit station comprises a fixed frame base, a sliding frame, and a footboard member, the footboard member being fixed in the front of the sliding frame. The sliding frame is arranged within the fixed frame base, being in sliding connection with the fixed frame base, and horizontally extending from and retracting to the fixed frame base with the guidance of guide rails and guiding means. A driving motor is fixed on the fixed frame base, and racks are fixed on the sliding frame, the racks being driven by the driving motor, pushing or pulling the sliding frame to extend from or retract to the fixed frame base.

Abstract: Disclosed is a safety footboard for a rail transit platform. The safety footboard for a rail transit station comprises a fixed frame base (401), a sliding frame (402), and a footboard member (403), the footboard member (403) being fixed in the front of the sliding frame. The sliding frame (402) is arranged within the fixed frame base (401), being in sliding connection with the fixed frame base, and horizontally extending from and retracting to the fixed frame base (401) with the guidance of guide rails and guiding means. A driving motor (404) is fixed on the fixed frame base (401), and racks (405) are fixed on the sliding frame (402), the racks (405) being driven by the driving motor, pushing or pulling the sliding frame (402) to extend from or retract to the fixed frame base (401). The safety footboard can effectively avoid potential safety hazards brought by a gap between a platform and a train door, and does not form obstruction to a moving train.
