Organic light emitting diode display device and manufacturing method thereof

A manufacturing method of an organic light emitting diode display, the method comprising:

• forming a first piezoelectric material layer and a second piezoelectric material layer inside a flexible upper substrate using a piezoelectric material;
• forming a first electrode inside the first piezoelectric material layer and a second electrode inside the second piezoelectric material layer;
• forming a pixel definition layer having an opening by stacking an organic material inside a flexible lower substrate and performing exposure thereon;
• forming a conductive spacer on the pixel definition layer;
• forming an organic light emission layer in the opening of the pixel definition layer;
• and
• forming a common electrode to cover the pixel definition layer and organic light emission layer except at the projection and a protrusion electrode.
