Abstract:
The present invention provides a manufacturing method of a color filter substrate, in which a layer of photoresist layer of a negative photoresist resin material is first formed on the color filter film layer; then, back side exposure is conducted on the photoresist layer from the underside of the backing plate so that a part of the photoresist layer that is adjacent to the backing plate gets cured for subsequently forming a planarization layer; afterwards, a mask is used to conduct front side exposure on the photoresist layer from the backing plate to form post spacers; and finally, the photoresist layer that has been subjected to exposure twice is subjected to development to remove a portion of the photoresist layer that has not been cured so as to form, simultaneously, a planarization layer and post spacers located on the planarization layer. This, when compared to an existing manufacturing method of a color filter substrate, can greatly simplify operation flow and thus greatly reduce investment on manufacturing line facility and lower down manufacturing costs of products and potential risks of unexpected problems occurring in the manufacturing process and shortening product manufacturing cycle.

Claim (Index 5):
The manufacturing method of the color filter substrate as claimed in  claim 2 , wherein the main post spacer and the sub post spacer are located above and correspond to the black matrix.
