Display apparatus and method for fabricating display apparatus

A display apparatus comprising:

• a first pixel;
• a second pixel adjacent to the first pixel;
• a first insulating layer;
• and
• a second insulating layer over the first insulating layer,
• wherein the first pixel comprises:
• a first pixel electrode;
• a first EL layer covering the first pixel electrode;
• a third insulating layer in contact with a first part of a top surface of the first EL layer;
• and
• a common electrode over the first EL layer and the third insulating layer,
• wherein the common electrode is in contact with a second part of the top surface of the first EL layer,
• wherein the first EL layer is sandwiched between the first pixel electrode and the common electrode,
• wherein the first EL layer comprises a first organic compound,
• wherein an amount of an organic compound that comprises an oxide of the first organic compound or a partial structure of the first organic compound and is contained in the first EL layer is greater than 0 and less than or equal to 1/10 of an amount of the first organic compound contained in the first EL layer,
• wherein the second pixel comprises:
• a second pixel electrode;
• a second EL layer covering the second pixel electrode;
• a fourth insulating layer in contact with a first part of a top surface of the second EL layer;
• and
• the common electrode over the second EL layer and the fourth insulating layer,
• wherein the first insulating layer is in contact with a top surface and a side surface of the third insulating layer, a top surface and a side surface of the fourth insulating layer, a side surface of the first EL layer, and a side surface of the second EL layer,
• wherein the first insulating layer, the third insulating layer, and the fourth insulating layer each comprise an inorganic material,
• wherein the second insulating layer comprises an organic material,
• wherein a first part of the second insulating layer overlaps with the first pixel electrode,
• wherein a second part of the second insulating layer overlaps with the second pixel electrode,
• wherein, in a cross-sectional view, a side surface of the second insulating layer has a tapered shape and a top surface of the second insulating layer has a convex shape,
• wherein a taper angle of the tapered shape of the side surface of the second insulating layer is less than 90°, and
• wherein the common electrode overlaps with the second insulating layer.
