Abstract
A display apparatus including a flexible substrate, a plurality of light emitting devices spaced apart from one another and disposed on the flexible substrate, and a light shielding layer disposed between the light emitting devices, and partially covering the light emitting devices to define light extraction surfaces, in which a distance between adjacent light extraction areas is the same.
Claims19
A light emitting device comprising:
- a first insulating layer including a first area and a second area having a greater thickness than the first area;
- a light emitting stacked structure including a plurality of light emitting parts sequentially disposed one over another along a first direction on the first area of the first insulating layer;
- a plurality of via patterns disposed on the light emitting stacked structure and having substantially the same length along the first direction;
