    摘要: Provided in the present disclosure are a light-emitting device, a display apparatus having the same, and a lighting apparatus. The light-emitting device includes a light-emitting unit disposed in a sub-region. The light-emitting unit includes a light-emitting functional layer, a light extraction functional layer and a part of a light transmissive substrate, which are disposed in a stacked manner. The light extraction functional layer is located on a light-exiting side of the light-emitting functional layer. A straight line segment that passes through geometric center of a light-exiting surface of each light-emitting unit and whose two ends are respectively connected with edge line of the light-exiting surface is defined as a first straight line segment, and the shortest length of the first straight line segment is defined as W. In a direction perpendicular to the light transmissive substrate, a thickness of the light-emitting unit without reflective electrode is T.
