Abstract
In one example, a photoresist composition includes about 1 to about 70 parts by weight of a first binder resin including a repeat unit represented by the following Chemical Formula 1, about 1 to about 70 parts by weight of a second binder resin including a repeat unit represented by the following Chemical Formula 2, about 0.5 to about 10 parts by weight of a photo-acid generator, about 1 to about 20 parts by weight of a cross-linker and about 10 to about 200 parts by weight of a solvent. The photoresist composition may improve the heat resistance and adhesion ability of a photoresist pattern. wherein Rand Rindependently represent an alkyl group having 1 to 5 carbon atoms, and n and m independently represent a natural number.
