Manufacturing method of display device

A manufacturing method of a display device, comprising:

• a first step of forming a first pixel electrode and a second pixel electrode;
• a second step of depositing a first EL film over and in contact with each of the first pixel electrode and the second pixel electrode;
• a third step of forming a first sacrificial film to cover the first EL film;
• a fourth step of processing the first sacrificial film and the first EL film to expose the second pixel electrode and form a first EL layer over the first pixel electrode and a first sacrificial layer over the first EL layer;
• a fifth step of depositing a second EL film over the first sacrificial layer and the second pixel electrode;
• a sixth step of forming a second sacrificial film to cover the second EL film;
• a seventh step of processing the second sacrificial film and the second EL film to expose the first sacrificial layer and form a second EL layer over the second pixel electrode and a second sacrificial layer over the second EL layer;
• and
• an eighth step of removing the first sacrificial layer and the second sacrificial layer.
