The invention provides a 
liquid crystal display mother board and a manufacturing method thereof. The 
liquid crystal display mother board comprises an array substrate and a 
color film substrate which are oppositely arranged, a clamping structure which is arranged between the array substrate, the 
color film substrate and is made of a 
photoresist and a residual material supporting the non-display region of the 
liquid crystal display mother board and connecting the array substrate and the 
color film substrate, wherein the array substrate is provided with a plurality of TFT substrates arranged in an arrayed mode; the clamping structure is used for replacing a virtual sealing frame 
adhesive and an annular sealing frame 
adhesive. The clamping structure made of the 
photoresist replaces the commonvirtual sealing frame 
adhesive and the annular sealing frame adhesive to achieve the same effect, and due to the fact that the clamping structure can be manufactured through a common 
exposure technology in the manufacturing process of the array substrate or the color film substrate, the requirement for the manufacturing process of 
coating the virtual sealing frame adhesive and the annular sealingframe adhesive is lowered, and the product 
pitch time is shortened; the clamping structure is manufactured in an 
exposure mode, the precision is higher, the floor area is small, and therefore the product cost is lowered.
