Abstract
A thin film transistor array panel according to an exemplary embodiment includes a first colored member overlapping a thin film transistor and a plurality of second colored members simultaneously formed on the first colored member. Accordingly, it is possible to prevent light leakage current of the thin film transistor, to easily repair deterioration of the thin film transistor, to prevent light leakage of a peripheral area and between color filters, and to form stable patterns.
