Abstract
Provided is a high-definition or high-resolution display device. This display device comprises a first light-emitting element and a second light-emitting element, the first light-emitting element and the second light-emitting element each having the function of emitting light of different colors. The first light-emitting element has a first pixel electrode, a first EL layer on the first pixel electrode, and a common electrode on the first EL layer. The second light-emitting element has a second pixel electrode, a second EL layer on the second pixel electrode, and a common electrode on the second EL layer. The first EL layer has a first layer on the first pixel electrode and a first light-emitting layer on the first layer. The first layer has a hole injection layer. The angle formed between a side surface of the first pixel electrode and the bottom surface of the first pixel electrode is 60 degrees to 140 degrees, inclusive. The ratio (T1 / T2) of the film thickness T1 of the first pixel electrode with respect to the film thickness T2 of the first layer being 0.5 or greater.
