A photoresist composition for a spinless coater includes a novolak resin having a weight average molecular weight of about 2,000 to about 15,000, a diazide based photosensitive compound and a volatile organic solvent. The photoresist composition is applied to a substrate of a liquid crystal display apparatus to reduce blots and enhance application uniformity. A highly volatile solvent, such as n-propyl acetate (nPAC) or n-butyl acetate (nBA) is used in the photoresist composition as the volatile organic solvent. The photoresist composition including the volatile organic solvent gives a photoresist film that has a uniform thickness. Hence, the generation of small resin blots and thick blots may be reduced. |
