The present disclosure provides a liquid crystal display panel and a manufacturing method thereof. The manufacturing method includes providing a first substrate and a second substrate; forming a color filter layer on the second substrate; forming a protective layer on the color filter layer; removing a portion of the protective layer; installing a first photo spacer and a second photo spacer on the protective layer, where the first photo spacer is disposed on a partial region of removing the protective layer; forming a liquid crystal layer between the first substrate and the second substrate; and a first distance between a top of the first photo spacer and the first substrate is less than a second distance between a to of the second photo spacer and the first substrate.
