Abstract: Provided is a display device including: a base material; a plurality of light-emitting elements located over a first surface of the base material and having an emission region; and a first trench located over a second surface of the base and overlapping with a non-emission region sandwiched between the emission regions of two adjacent light-emitting elements selected from the plurality of light-emitting elements. Alternatively, the display device includes: a base material; a plurality of pixels located over a first surface of the base material and having a light-emitting element; a first trench located over a second surface of the base material and overlapping with a region sandwiched between two adjacent pixels selected from the plurality of pixels; and a ridge located over the first surface of the base material, overlapping with the first trench, and consisting of the base material.

Abstract: Provided is a display device including a pixel. The pixel has: a conductive film; an interlayer insulating film over the conductive film; a first electrode over the interlayer insulating film; an insulating film over the first electrode; an organic layer over the first electrode and the insulating film; and a second electrode over the organic layer. The interlayer insulating film has a first opening portion overlapping with the conductive film. The insulating film covers the first opening portion. A first region of the organic layer in contact with the first electrode surrounds the insulating film. An area defined by a periphery of the first region has at least two symmetry axes in a direction parallel to a surface of the substrate.
