Display apparatus, method of manufacturing display apparatus, and electronic apparatus including display apparatus

A method of manufacturing a display apparatus, the method comprising:

• forming a first functional layer over a first electrode;
• forming a first-1 light-emitting unit layer over the first functional layer by using a first-1 mask having a first-1 opening having a first-1 area;
• forming a first charge generation layer over the first-1 light-emitting unit layer by using a first-2 mask having a first-2 opening having a first-2 area that is less than the first-1 area;
• forming a first-2 light-emitting unit layer over the first charge generation layer by using a first-3 mask having a first-3 opening having a first-3 area;
• and
• forming a second electrode over the first-2 light-emitting unit layer,
• wherein the first-2 area is greater than or equal to 40% and less than 100% of the first-1 area.

An electronic apparatus comprising:

• a memory storing data information;
• a processor configured to generate a data signal and/or a control signal based on the data information;
• and
• a display apparatus configured to operate based on the data signal and/or the control signal,
• wherein the display apparatus comprises:
• a first electrode;
• a first functional layer over the first electrode;
• first to third light-emitting units over the first functional layer;
• and
• a second electrode over the first to third light-emitting units,
• wherein the first light-emitting unit comprises:
• a first-1 light-emitting unit layer having a first-1 area in a plan view;
• a first charge generation layer over the first-1 light-emitting unit layer, in the first-1 light-emitting unit layer in the plan view, and having a first-2 area that is less than the first-1 area;
• and
• a first-2 light-emitting unit layer over the first charge generation layer and overlapping the first-1 light-emitting unit layer,
• wherein the first-2 area is greater than or equal to 40% and less than 100% of the first-1 area.
