The present invention relates to a liquid crystal display (LCD) panel and its manufacturing method. The LCD panel comprises a first substrate, a second substrate, a sealant, and a barrier wall. The first substrate and the second substrate are disposed relatively. The sealant disposed surrounding between the first substrate and the second substrate. The barrier wall is disposed at the outer side of the area surrounded by the sealant, and the barrier wall is respectively abutted against the first substrate and the second substrate. In summary, the present invention could improve the overflow of the sealant, reducing the difficulty for narrow frame design and the requirement for cutting precision of the LCD panel.
