Organic thin film transistor display substrate, method of fabricating the same, and display apparatus having the same

A method of fabricating an organic thin film transistor display substrate, the method comprising:

• preparing a substrate including a plurality of pixel areas defined thereon;
• forming a gate electrode on the substrate;
• forming a gate insulating layer on the substrate to cover the gate electrode;
• forming a source electrode and a drain electrode spaced apart from the source electrode on the gate insulating layer;
• forming a color filter on the source electrode and the drain electrode, the color filter layer including a first opening formed therethrough to expose the source electrode and the drain electrode;
• and
• forming an organic active pattern in the first opening.

A display apparatus comprising:

• a first substrate including a plurality of pixel areas defined thereon;
• an organic thin film transistor arranged in each pixel area and including an organic active pattern;
• a color filter arranged in each pixel area and provided with a first opening filled with the organic active pattern;
• a pixel electrode arranged on the color filter and electrically connected to the organic thin film transistor;
• and
• a second substrate facing the first substrate.
