Abstract
In an organic thin film transistor display substrate, a thin film transistor and a pixel electrode electrically connected to the thin film transistor are formed on an array substrate in which a plurality of pixel areas is defined. Also, color filters are formed in the pixel areas. Each color filter is provided with an opening formed therethrough and an active pattern of thin film transistor is received into the opening. Since the active pattern is formed on the array substrate through an inkjet method, the color filter may receive the active pattern therein in lieu of a bank pattern, thereby simplifying the structure of the organic thin film transistor display substrate and improving its productivity.
