Claim:
1. A method for producing spacers in a liquid crystal panel, comprising the following steps: (a) exposing a material layer adjacent to a side of a thin film transistor (TFT) substrate of said liquid crystal panel by a mask with a pre-set pattern, to form a groove in said material layer, wherein the material layer on the side of said TFT substrate being a color film layer or an organic protective layer and an exposure energy of said exposure ranges from 10 to 100 mJ/cm2; (b) forming a main spacer and a side spacer in an opposite substrate, wherein the height of the side spacer is higher than that of the main spacer; and (c) assembling said TFT substrate and the opposite substrate together, such that the main spacer of the opposite substrate abuts against the TFT substrate and the side spacer extends into said groove; wherein: a layer of ITO pixel electrodes is further provided on said material layer where the groove is formed, and the opposite substrate is provided with a black matrix on an outside surface thereof so that the main spacer and the side spacer are separated from the black matrix.
