Display device comprising partition covering adjacent pixel electrodes and manufacturing method of display device

A display device comprising:

• a first display element comprising a first pixel electrode, a first EL layer, and a common electrode;
• a second display element comprising a second pixel electrode, a second EL layer, and the common electrode;
• a first insulating layer covering an end portion of the first pixel electrode and an end portion of the second pixel electrode;
• and
• a second insulating layer over the first insulating layer,
• wherein the first EL layer is placed over the first pixel electrode and the second insulating layer,
• wherein the second EL layer is placed over the second pixel electrode and the second insulating layer,
• wherein the first insulating layer comprises an inorganic material,
• wherein the second insulating layer comprises an organic material,
• wherein the first insulating layer and the second insulating layer are part of a first partition, and
• wherein each layer of the first partition overlaps with the end portion of the first pixel electrode and the end portion of the second pixel electrode.

A method for manufacturing a display device, comprising steps of:

• forming a pixel electrode;
• forming a first insulating film over the pixel electrode;
• forming a second insulating layer over the first insulating film to cover an end portion of the pixel electrode;
• forming a first insulating layer covering the end portion of the pixel electrode by etching the first insulating film using a resist mask;
• forming an EL layer over the pixel electrode and the second insulating layer;
• and
• forming a common electrode over the EL layer,
• wherein the first insulating layer comprises an inorganic material,
• wherein the second insulating layer comprises an organic material, and
• wherein the common electrode is not in contact with the first insulating layer and the second insulating layer.
