ABSTRACT:
A photoresist composition, a method for forming a film pattern using the photoresist composition, and a method for manufacturing a thin film transistor array panel using the photoresist composition are provided. In one embodiment, a photoresist composition includes an alkali-soluble resin, a photosensitive compound, and an additive, for advantageously providing a uniform photoresist in a channel region.
