Display device and method for fabrication thereof

A method for fabricating a display device, the method comprising:

• forming a plurality of pixel electrodes spaced apart from each other and a pixel defining layer exposing the plurality of pixel electrodes;
• forming a first bank material layer on the pixel defining layer;
• forming a multi-layered second bank material layer on the first bank material layer;
• etching a portion of the multi-layered second bank material layer and the first bank material layer;
• etching a side of the first bank material layer to expose a lower surface of the multi-layered second bank material layer;
• forming a light emitting layer on one of the plurality of pixel electrodes;
• forming a light emitting pattern layer on the multi-layered second bank material layer;
• forming a common electrode on the light emitting layer;
• forming an electrode pattern layer on the light emitting pattern layer;
• forming an inorganic material layer on the electrode pattern layer;
• etching a portion of the inorganic material layer;
• and
• etching the light emitting pattern layer and the electrode pattern layer to expose the multi-layered second bank material layer.
