In the existing liquid crystal display panel, spacers are usually provided to maintain the cell gap between the upper substrate and the lower substrate of the display panel. However, in the process of manufacturing a curved display panel, if the upper and lower substrates are misaligned, problems such as gap errors, spacers scratching other film surfaces, or spacers overlapping with ridges (Tsuno) will be caused.
