A liquid crystal panel and a LCD are provided. The liquid crystal panel comprises an array substrate (1) and a color filter substrate disposed (2) as opposed to each other and a liquid crystal layer (3) disposed therebetween, wherein a first barrier layer (5) is disposed on the array substrate (1), the first barrier layer (5) comprises a first part (11) configured to reflect light and a second part (12) configured to transmit light, the first and second parts (11, 12) are arranged alternately; a second barrier layer (6) is disposed on the color filter substrate (2), the second barrier layer (6) comprises a third part (13) configured to reflect light and a fourth part (14) configured to transmit light, the third and fourth parts (13, 14) are arranged alternately; the first part (11) of the first barrier layer (5) and the fourth part (14) of the second barrier layer (6) are equal in width and aligned to each other, the second part (12) of the first barrier layer (5) and the third part (13) of the second barrier layer (6) are equal in width and aligned to each other, such that light passing through the second part (12) of the first barrier layer (5) is reflected by the third part (13) of the second barrier layer (6), and light passing through the fourth part (14) of the second barrier layer (6) is reflected by the first part (11) of the first barrier layer (5). The liquid crystal panel of the invention realizes dual-side display at a lower cost.
