Abstract:
A display apparatus with a wide viewing angle is provided. The display apparatus includes a first light-emitting element and a second light-emitting element over a substrate. The first light-emitting element includes a first pixel electrode, a first organic layer, and a common electrode, and the second light-emitting element includes a second pixel electrode, a second organic layer, and the common electrode. In a top view of the substrate, the first light-emitting element includes a first side and a second side that is shorter than the first side. An absolute value of a difference between a chromaticity difference between a chromaticity in a front direction and a chromaticity in a first direction and a chromaticity difference between the chromaticity in the front direction and a chromaticity in a second direction is less than or equal to 0.05. A projection of the first direction onto the substrate is parallel to the first side, and a projection of the second direction onto the substrate is parallel to the second side. An angle formed by the first direction and a normal direction of a surface of the substrate is 70°, and an angle formed by the second direction and the normal direction of the surface of the substrate is 70°.
