The invention provides a display apparatus comprising: a plurality of thin film transistors; a protective film formed on the thin film transistor; a plurality of pixel electrodes formed on the protective film and electrically connected with the thin film transistors; a partition wall layer partitioning the pixel electrodes adjacent to each other, the partition wall layer including a main exposure portion exposing the pixel electrode and a sub-exposure portion protruded and extended from the main exposure portion whereby the problem of non-uniform coating of ink in the corners of pixel electrodes is overcome.
