PURPOSE: A thinner composition is provided, for removing the photoresist for a thin film transistor LCD device, which is aggregated at the edge of a board completely, thereby improving the production yield in TFT-LCD preparation. CONSTITUTION: The thinner composition comprises 1-25 wt% of an alkyl amide of the formula 1; and 75-99 wt% of an organic solvent of the formula 2, wherein R1, R2 and R3 are independent each another and are H or a straight alkyl group of C1-C2, and at least one among them is an alkyl group; and R4, R5 and R6 are independent each another and are a straight alkyl group of C1-C3. Preferably the alkyl amide is selected from the group consisting of N-methyl acetamide, dimethyl formamide, dimethyl acetamide and their mixtures; and the organic solvent is selected from the group consisting of propylene glycol monomethyl ether acetate, β-methoxy isobutyric acid methyl ester, methyl 3-methoxy propionate and their mixtures. |
