A light-emitting array includes a semiconductor LED structure, multiple outcoupling structures, multiple independent first electrical contacts, and second electrical contact(s). The LED structure extends contiguously over the array. The second electrical contacts are in electrical contact with the second semiconductor layer. Each outcoupling structure is a protruding portion of the second semiconductor layer. Each first electrical contact includes a circumscribed electrode layer opposite a corresponding outcoupling structure. Each outcoupling structure and corresponding first electrical contact define a corresponding discrete, circumscribed pixel region within the contiguous area of the array, each pixel region separate from the others. Some light emitted in the pixel region is collected or redirected by the outcoupling structure to exit the outcoupling structure and propagate away from the array.

The lighting device disclosed at an embodiment of the invention includes a substrate; a first reflective layer disposed on the substrate and having a plurality of reflection patterns; a light source disposed on the substrate; a resin layer disposed on the first reflective layer, and a second reflective layer disposed on the resin layer and having a plurality of holes, wherein an arrangement form of the plurality of holes is the same as that of the plurality of reflection patterns.

A light-emitting substrate and a manufacturing method are provided. The light-emitting substrate includes a substrate and light-emitting devices arranged at intervals thereon. Light-shielding structure is at a gap between the light-emitting devices and shields light emitted from the light-emitting devices laterally. The light-shielding structure and light-emitting devices do not overlap in a target light-emitting direction of the light-emitting devices, or overlap in a target light-emitting direction of the light-emitting devices by being less than a width. Since the light-shielding structure is at the gap between the light-emitting devices, light emitted by the light-emitting devices laterally is shielded, avoiding light from irradiating other devices and causing light crosstalk. Light from the light-emitting devices in the target light-emitting direction is not shielded or not completely shielded, eliminating an adverse effect on light efficiency of the light-emitting devices, improving the light-emitting effect of the light-emitting surface of the light-emitting substrate.
